3. Transport Common
DANGER-

Do not step under a unit suspended by a crane or other lifting mechanism for transport; otherwise, injury or death may
result.

CAUTION-Be careful not to drop the unit.

	When a hanging bolt or hole is provided, be sure to use it. After mounting a unit on a machine, do not hoist the entire
machine by using the hanging bolt or hole; otherwise, personal injury or damage to the equipment and/ or lifting device
may result.
-

Before hoisting, refer to the nameplate, crate, outline drawing, catalog, etc. for the weight of the unit. Never hoist a unitthat exceeds the load capacity of the crane or other mechanism being used to lift it; otherwise, personal injury or damage
to the equipment and/ or lifting device may result.

-

When the products are lifted, use suitable lifting parts, and confirm that eye-bolts and nuts are not loose.

-

Always drain oil before mounting, moving, and transporting the machine lubricated by oil.
Moving the machine with lubricating oil in may cause oil to escape from the air vent, etc.

9Common

4. Installation
DANGER-

Do not use a standard unit in an explosive atmosphere (which is likely to be filled with explosive gas or steam). Under
such conditions, an explosion proof motor should be used; otherwise, electric shock, personal injury, explosion fire, or
damage to the equipment may result.

-

In the case of an explosion proof motor , use a motor that has specifications that are appropriate for a dangerous
location (a location where gas or volatile vapor is present); otherwise explosion, ignition, electric shock, injury, fire, or
equipment damage may result.
When a flameproof motor is driven by an inverter , install an inverter in a place free from explosive gas since the inverter
itself is not explosion proof. Otherwise, electric shock, personal injury, explosion fire, or damage to the equipment may result.

-

CAUTION--

Do not use the products for purposes other than those shown on the nameplate or in the manufacturing specifications;otherwise, electric shock, personal injury, or damage to the equipment may result.
Do not place flammable objects around the gearmotor; otherwise, fire may result.
Do not place any object around the gearmotor or reducer that will hinder ventilation. Insufficient ventilation can cause
excessive heat that may result in burns or fire.
Do not step on or hang from the gearmotor or reducer; otherwise injury may result.
Do not touch the shaft end of the gearmotor or reducer, inside keyways, or the edge of the motor cooling fan withbare hands; otherwise, injury may result.
Please install loss prevention device such as oil pan to the machine which is vulnerable to oil especially (machine for foodprocessing and machine for clean room, and so on) in case oil or grease leaks; otherwise, the product may fail because ofoil leakage.
Always drain oil before mounting, moving, and transporting the model lubricated by oil. Moving the machine with the
lubricating oil in may cause oil to escape from the air vent, etc.

4-3 When Load Condition Is Critical
In cases of extreme vibration or frequent startup, it is recommended to use dowell pin for the foot unit, and use a mounting bolt of atleast class 8.8 (JIS B 1051) strength.

4-4 Flange Type Assembly Points (Models: CNFM, CHFM, CNF, CHF, etc.)[1] R emove the fan cover if there is one installed (reducer frame size of 6160 or more).
[2] R emove the nut and bolt for ring gear housing. Take care when loosening the nut, as the bolt for ring gear housing may rotate together.
[3] When the device is shipped, different size of nut from the one for ring gear housing may be assembled between nut for ring gear
housing and flanged casing. Remove this nut, as it is used as a spacer for preventing damage to the faces of the nut for ring gear
housing and flanged casing, as well as for covering non-threaded portion of bolt for ring gear housing.
[4] Install the device to the driven machine, and tighten the nut and bolt for ring gear housing with the tightening torque shown in Table 4.2.
- Disassembly prevention nuts are installed at 2 locations of the bolt for ring gear housing (opposing angles) to prevent disassembly of
the reducer in case the bolt for ring gear housing is removed. Do not remove the disassembly prevention nuts. Removing them may
result in the flanged casing, ring gear housing, internal cover, motor and other parts disassembling and falling off, and may cause injury.
- Using only the disassembly prevention nuts with the nut for ring gear housing removed does not generate a sufficient level of
torque. Do not use only the disassembly prevention nuts for ring gear housing for long periods of time, move them excessively or
subject them to shock. Lubricant or grease may leak if there gaps develop between any of the mating faces.
- Tightening the nut for ring gear housing changes the axial force of the disassembly prevention nuts, and may result in them coming
loose. To remove the CYCLO Drive after temporarily assembling the device to the driven machine, check that the disassembly
prevention nuts have not become loose.

shafts are slanted, misaligned, or if the key is partially engaged.
[6] F asten the motor and adapter plate (internal cover) using the motor mounting bolt. Tighten after confirming that the motor spigot
is securely inserted into the adapter plate (internal cover) spigot. If the bolt is tightened when the spigot is not inserted, uneventightening will result in damage to the internal bearing and other components.

125. Coupling With Other Machines Common
CAUTION-

Confirm the rotation direction before coupling the unit with the driven machine. Incorrect rotation direction may
cause personal injury or damage to the equipment.

-

When operating the product alone (uncoupled), remove the key that is temporarily attached to the slow speed shaft;otherwise the key could fly off, and injury may result.

-

Cover rotating parts; otherwise, injury may result.

-

When coupling the product with another machine, check that the centering, the belt tension and parallelism of
the pulleys are within the specified limits. When the unit is directly coupled with another machine, check that thedirect coupling accuracy is within the specified limits. When a belt is used for coupling the unit with another machine,
check the belt tension. Correctly tighten bolts on the pulley and coupling before operation; otherwise there is a risk of
injury due to scattering the broken pieces or of damage to the products.

5-1 Checking Rotational Direction(1) For Gearmotor
Table 5-1 shows the direction of slow speed shaft rotation when wiring is performed as on P18–31.
Table 5-1 Slow Speed Shaft Rotation Direction (Gearmotor)

When using a vector motor, or other manufacturer’s motor (There are some models made by other manufacture.), follow the operation manual for that motor.
This manual shows wiring for motors with Japanese standard specifications. Please consult with us for motors with overseas
specifications.

DANGER-

Do not handle the unit when cables are energized. Be sure to turn off the power; otherwise, electric shock may result.

-Connect a power cable to the unit according to the diagram shown inside the terminal box or in the maintenancemanual; otherwise, electric shock or fire may result.

-

Do not forcibly bend, pull, or clamp the power cable and lead wires; otherwise, electric shock or fire may result.

-

Correctly ground the grounding bolt; otherwise, electric shock may result.

-

The lead-in condition of an explosion proof motor shall conform to the facility’s regulations, electrical codes, andexplosion proofing standard, as well as the maintenance manual; otherwise, electric shock, personal injury, explosion, fireor damage to the equipment may result.

CAUTION-

When wiring, follow the facility’s regulations and electrical codes; otherwise, burning, electric shock,injury, or fire may result.

-

The motor is not equipped with a protection device. However, it is compulsory to install an overload protector according
to facility electrical codes. It is recommended to install other protective devices (earth leakage breaker,etc.), in addition to an overload protector, in order to prevent burning, electric shock, injury, and fire.

-

Never touch the terminals when measuring insulation resistance; otherwise, electric shock may result.

-

When using a star-delta starter , select one with an electromagnetic switch on the primary side (3-contact point type);
otherwise, fire may result.

-

Voltage PWM inverters that use IGBT generate high-voltage surges at the motor terminals, which may degrade theinsulation on the motor windings. Especially such as when the cable is long in the 400V class, a surge voltage over 1300V
occurs. Therefore, in this case, install an LCR filter, AC reactor, etc. between the inverter and motor to inhibit the surge
voltage.

-

When using a motor with brake , do not turn on connection power to the brake coil when the motor is stopped.
Otherwise coil burnout fire, may result. Also, mistaken wiring could damage the rectifier.
When using an explosion proof motor driven by an inverter , use one inverter for one motor. Use the approved inverter
for the motor.

-

When measuring the insulation resistance of an explosion proof motor , confirm that there is no gas or explosive vapor
in the vicinity, in order to prevent possible explosion or ignition.

-

If ambient temperature exceeds 60℃ , place the rectifier in a location where the temperature is 60℃ or less. In this case,always protect the entire rectifier with a cover. However, ambient temperature conditions for standard units with andwithout brakes must be −10 to 40℃ . (Manufacture with special specification is required for operation in an environment
where ambient temperature exceeds 40℃ .)-Long cables cause large voltage drops. Select cables with appropriate diameter so that the voltage drop will be no
greater than 2%.

-

After wiring outdoor types and explosion proof types , check that terminal box mounting bolts are not loose, andcorrectly attach the terminal box cover.

6-2 Measuring Insulation Resistance
When measuring insulation resistance, always disconnect the control board and measure the motor alone.
Measure insulation resistance before wiring. Insulation resistance (R) is changed by a number of factors, including motor output,
voltage, type of insulation, winding temperature, moisture, degree of fouling, time used, and amount of time test voltage is applied.
However, normally, it must be above the values in Table 6-1.

Low insulation resistance is a sign that there is an insulation failure. Do not apply power. Consult an accredited maintenance shop.

6-3 Coordination of System Protection- Use a wiring breaker for short circuit proofing.
- Use an overload protection device designed to handle currents that exceed the rated current on the nameplate.
- For Increased safety motor , use an overload protection device capable of protecting the locked rotor current on the nameplate
within the allowable locking time.

- This diagram shows cases for motors with standard Japanese domestic specifications. Please consult with us for motors withoverseas specifications.
- When using inverter for 400V class 3-phase motor / high-efficiency 3-phase motor, the motor must be insulated.
In the case of motor with axial fan (totally enclosed, fan motor ventilation type) , note the following items.
- Also connect a power source to the axial fan.
- For an indoor 400V class ( except flameproof type ), the axial fan power source voltage will be 200V class. For the motor with special
specifications, specifications may differ from the above. Check the manufacturing specifications.
- Connect the fan so that it rotates in the same direction as that shown on the nameplate for direction of rotation.
(Normally, the air from the fan will blow in a direction from the anti-load side to the load side.)- When the motor is shut down for a long period, also shut down the axial fan motor.
- Wire the mounted thermostat.
- Thermostat specification: Terminal symbols: T1, T2 and P1, P2
Operating function: Normal close (b contact point)
Operating temperature: 135℃ (for thermal class 155 (F)) Maximum current: DC 24V, 18A; AC 230V, 13A

Temperature rises during operation will differ according to model and type. However the difference between the gear unit surface temperatureand the ambient temperature should be approximately 60℃ . (For frame size 6060 – 6125, and SK series , approximately 40℃ ) In thiscase, there is no particular problem if fluctuation is slight.

)

Is the oil level below the red line at the top of the oil gauge when the machine is at rest?
If the oil level is below the top red mark when the machine is at rest, fill up lubricating oil to the mark. Do not add while the machine isrunning.
Is the oil level significantly different compared to the level when the lubrication state is stable?
The bottom red mark is an auxiliary mark serving as a guideline to check oil level while the machine is running.
Are the oil signal and flow gauge working properly?
Not working properly is a sign of improper reducer lubrication, due to factors including insufficient oil, pump damage and plugged
pipes. In this case, immediately stop the machine and inspect it.
Is the lubricating oil contaminated?
To check oil contamination, extracting oil while the machine stops and using the oil gauge are effective.
If the oil gauge is contaminated, promptly change it.
Are oil or grease leaking from the gear unit? Are the oil seal sliding surfaces corroded?
Are the mounting bolts loose?
Are the chain or V-belt loose?

- If any abnormality is discovered during the daily inspection, take measures in accordance with “9. Troubleshooting” (P73, 74). If these actions do not solve the issue,
immediately contact the nearest authorized maintenance shop.

- It will take some time for high-viscosity oil to reach a uniform level. Be careful not to fill with too much oil. (If oil is filled above the
top red line, churning heat may raise the temperature.)- Use the lower red line of the oil gauge as a guideline for the oil level while the machine is running. (The oil level may drop below
the bottom red line immediately after the machine starts. It will return when oil viscosity drops as the machine runs. Therefore, thisis not a problem.)- For daily oil level management see Table 8-1 on P36.

8. Daily Inspection and Maintenance Common(4) Procedures for Filling and Discharging
Grease replenishment procedure for grease lubricated models (excluding long-life grease lubricated models)[1] Remove the grease discharge plug from the flanged casing.
[2]Use a grease gun to replenish through the grease fittings of the internal cover or the motor flange bracket. Use the quantities
of grease shown on P42, Table 8-13 as guidelines. If a grease fitting has a metal cap, remove the cap before replenishing. After
replenishing, attach the metal cap.
[3] Replace the grease discharge plug.

Table 8-5 Location of Grease Fill andDischarge Port
(Example: Vertical, Gearmotor,
2 Stage Reduction)

Table 8-6 Grease Fitting with Metal Cap- Supply grease while the machine is running to improve grease distribution.
- In addition to being used for discharging grease, the grease discharge plug also functions as a pressure vent when replenishinggrease. Make certain to remove when replenishing.
- Replenish grease slowly.
- Replenishing more than the quantity shown in Table 8-13 may cause agitation heat, which raises the temperature, and may cause
grease to leak into the motor unit.
- Grease may leak out of the grease fitting after starting the machine. In such a case replace the grease fitting with one that has ametal cap.
- Be careful when handling the metal cap for the grease fitting as dropping it from a high place is dangerous.
- Contact the nearest authorized maintenance shop concerning changing all of the grease in a grease lubricated model.

8-5 Main Unit Maintenance- Although it will depend on operation conditions, maintenance with disassembly after approximately 20,000 hours or 3 to 5 years will
increase lifetime. Contact the nearest authorized maintenance shop regarding maintenance with disassembly.
- Oil seals have a lifetime. During long use, natural degradation and frictional wear will reduce effectiveness. Reducer operating
conditions and ambient environment will cause lifetime to widely vary. Given normal operation, (uniform load, running 10 hours perday, normal temperature) it is recommended to change them every 1 to 3 years. If the sliding surfaces of oil seals or V-rings show
signs of wear or corrosion, replace them with new ones. Because sliding surfaces for oil seals are made of carbon steel, take periodic
rust prevention measures not to spread rust on them by applying rustproof oil and so on, if there are exposed surfaces of steel. Please
consult with the nearest maintenance shop for the replacement of oil seal or V-ring.
- If stop and start are frequent, mounting bolts (or nuts) and ring gear housing fastening bolts (or nuts) may come loose. Periodicallycheck for looseness as this is a source of miss-alignment, oil leakages, and load unbalance.

8. Daily Inspection and Maintenance(4) Procedures for Filling and Discharging Grease for Open Bearings
See construction diagram 8-7.
[1]Remove the discharge port plug, and discharge the old grease. While the machine is running, replenish with new grease throughthe grease fitting.
      (Grease change will be incomplete if replenishing is done while the machine is stopped.)[2] Run the machine for approximately 10 minutes after the grease is inserted. Then fasten the discharge port plug.

- Overfilling could cause the bearing to overheat, grease to leak and other problems. Be careful.
- Do not think that it is allowable to replenish with a large quantity to extend the replenishment interval.
- Please maintain the machine properly. Neglecting replenishment when resuming operation, or periodic replenishment when themachine is operating could lead to abnormal wear, bearing noise, bearing burnout, and other problems.

8-7 Brake Maintenance and Inspection
DANGER-

Do not handle the unit when cables are energized. Be sure to turn off the power when working on the unit; otherwise, electric
shock may result.

-

When using the product for lifting, do not release the brake while an object is suspended; otherwise it could fall, causing an
accident.

-

Do not operate the machine while the brake is released by the manual brake release bolt; otherwise, falling, going out ofcontrol, or damage to the equipment may result.

-

Before operation turn power on and off to check brake action; otherwise falling or running out of control could occur.

-

Do not bring water or oils in contact with the brake. Brake torque degradation could cause falling or running out of control.

CAUTION-

After gap inspection and adjustment, do not operate with the fan cover removed; otherwise loose clothing may became caught
in these rotating parts and cause serious injury or death.

-

Changing brake linings requires experience. Consult with the nearest authorized maintenance shop.

Given normal operation conditions, brake mechanical lifetime is quite long at 2 million times (1 million times for FB-30, ESB-250
and ESB-250-2). These conditions include the moment of inertia for the load being no greater than the moment of inertia for thebrakemotor. However, please periodically inspect the brake gap (G). The brake lining wears after long hours of running time, making it impossible for the brake to release. When 2 million times is exceeded (1 million times for FB-30, ESB-250 and ESB-250-2), wear
and damage to mechanical parts may cause dropping or overdrive problems.

8-8 Brake Construction and Gap Inspection and Adjustment- The brake is spring activated (power-off type).
- The brake lining wears after long hours of operating the brake, making it impossible for the brake to release. Therefore please
periodically inspect the brake gap (G).
- If on inspection the gap is close to the limit, adjust the gap.
- In FB-1E – FB-4E a shock absorber is inserted between the stationary core and the armature plate to reduce the noise that results fromthe braking action.
When inspecting, be careful so that the gap gauge, other measuring tool or anything else does not damage the shock absorber orcause it to fall out.
There is danger that brake noise will increase and the brake will not function properly if the shock absorber is damaged or falls out.

2.0- Gap Adjustment(1)

Manually release the brake following the procedure on P72.

(2)	Loosen the stopper [16] on the periphery of the center ring [1], and remove it. This will free the gap adjusting screws [2].
(See Figure 8-19)(3)	Insert the gap adjusting bar (customer to prepare an angle plate. See Figure 8-21) from between the outer disc [14] and thecenter ring [1] into a hole for a gap adjusting screw [2].
Rotating to the left as seen from the field [4] side, will narrow the gap. (See Figure 8-20)(4)Six attachment bolts [3] and 6 lock bolts [11] alternately pass through the space between the outer disc [14] and the center ring[1]. Rotating the gap adjusting bar will contact these bolts. There are 8 equally distributed holes for gap adjusting screws [2].
Adjust the gap G to the required value by repeating (3) each time the gap adjusting bar contacts a bolt,.

(5)

Select the point where hole and screw hole are closest to the required gap and attach the stopper [16] there.

(6)

After returning the manual brake release to its original state, turn power on and off to check brake action.

(7)

Attach the fan [7] and cover [8]. At this time coat the fan set screw [10] with Three Bond TB2365.

- Brake torque may not be at the prescribed level during initial operation. In such case, turn motor and brake power on and off underas lightest load as possible to rub the brake lining and the inner disc friction surfaces.
- When changing the brake lining and the inner disc, change the boss and leaf springs (for FB-5E – FB-15E, FB-20, FB-30, include thegap adjusting nuts) as a set.
- After 2 million or more cycles of operation, (for FB-30, ESB-250 1 million cycles or more), or after 10 years or more have passed since
shipment from the factory, inspect to check whether continued operation is possible, even if the lining or the inner disc has notreached the usable thickness limit.
- Check the following items concerning the condition of each mechanical part.
Are the material of linings split or chipped?
Is there any peeling or gap between the material of lining and the disc?
Does the spline unit of the brake lining and the inner disc exhibit any cracking, chipping, or stepped wear?
Is there any stepped wear on the surfaces around the stud bolts or armature plate?
- Change the brake lining and the inner disc, even if it has not reached the usable thickness limit, if 10 or more years have elapsed since
the manufacturing date and the brake is used outdoors or in a high-humidity environment, or if it is stored or rested for a long
period of time.

8-11 Changing the V-Ring and Waterproof Seal (Outdoor Type)V-rings and waterproof seals degrade over the years, losing their waterproofing abilities. Contact the nearest authorized maintenanceshop about every 3 years. If the sliding surfaces of oil seals or V-rings show signs of wear or corrosion, replace them with new ones.
Sliding surfaces are made of carbon steel, so rain water, condensation and other factors could cause rust to form and spread. Because
this could lead to oil seal damage, take periodic rust prevention measures.

8-12 Manually Releasing the Brake
To manually release the brake with the power off, operate the brake release mechanism as shown below.

■ FB Brakes (excluding FB-20, FB-30) (FB-01A1 – FB-05A1 are options)(1)First remove the brake release bolts from the 2 opposing angles and remove the release prevention spacers. Reinsert the bolts androtate with a hexagonal wrench to release the brake. Be careful not to over rotate the brake release bolts. (Rotate the brake releasebolts while checking if the brake is released.) (See Figures 8-37, 8-38)(2)After releasing the brake, to return it to its original condition, for safety, return the manual release prevention spacers that were

■ FB-20, FB-30(1)In the case of outdoor types, remove the lid on the window part of the the outdoor cover [33]. Remove the grommet [28] (indoortype), remove the brake release bolt [2] by using a hexagonal wrench (for an M8 hole bolt), and remove the rubber gasket [3] andthe manual release prevention spacer [4]. The brake will release when you again rotate the bolt by using the hexagonal wrench.
Be careful not to over rotate the brake release bolt. (Rotate the brake release bolt [2] while checking if the brake is released.) (SeeFigure 8-39)(2)After releasing the brake, to return it to its original condition, for safety, return the manual release prevention spacer and the rubber
gasket [3] that were removed in (1) to their original positions, and firmly tighten the brake release bolt [2]. (See Figure 8-40)N ext re-attach the grommet [28] (indoor type) in its original state. In the case of outdoor types, attach the lid on the window partof the the outdoor cover [33] as it was before.
- Note that if the rubber gasket [3] and the seal washer [5] for the brake release bolt [2] unit are not attached when returning tothe original state, dust-proofing and waterproofing capabilities will be lost.
Also, firmly tighten the brake release bolt [2]. Otherwise waterproofing capability may be lost.
Also make certain to return the grommet [28] (indoor type) or outdoor cover [33] window lid (outdoor type) to their originalstates.
- If the machine is operated when the brake release bolt has not been returned to its original position, in the worst case it ispossible that the manual release would function before maximum gap is obtained, and the brake would cease to function.
Therefore, make certain to always operate with the manual release prevention spacer attached.

11. Wiring

CYCLO Drive with Torque Limiter
DANGER- Do not handle the unit when cables are energized. Be sure to turn off the power when performing operations on the unit;
otherwise, electric shock may result.
- Connect a power cable to the unit in accordance with the maintenance manual; otherwise, electric shock or fire may result.
- Do not forcibly bend, pull, or clamp the power cable and lead wires; otherwise, electric shock or fire may result.

CAUTION- When wiring, follow the facility’s regulations and electrical codes to prevent burns, electric shocks, injuries, and fire.

11-1 Wiring for a Spring-Loaded Limit Switch(1) Limit Switch Type (1-Point Signal, 2-Point Signal, 3-Point Signal)
Dog- When the preset torque is reached, the dog activates the limit switch, which
outputs a signal.
- Depending on manufacturing specifications 1 – 3 point signal output isavailable.
(Types that have 1 – 3 limit switches.)

- The preset torque is shown at the center of the adjusting scale plate [1] in the figure below.
Torque values indicated by T1 and T2 are positioned at ± 150° from the center. Use T1 and T2 as points of reference when changing
the preset torque.
- When it is necessary to increase or decrease the original preset torque, use the adjustment bolt [2].
Adjust torque within a range of ± 25% of the preset torque.
Overscaling T1 and T2 is permitted within ± 25%. However, do not make adjustment in excess of the maximum preset torque. (See theselection table in the catalog.)- An index [4] is stamped in the cut on the side of the threaded section of the adjustment bolt [2]. The index [4] is aligned with the end
face of the case cover [3] when the mark [5] on the adjusting bolt [2] is located at the position of the preset torque on the adjusting
scale plate [1]. Make fine adjustments by using this alignment as a base. If the adjustment bolt is too tight or too loose, first reset theadjustment bolt to align the index [4] with the end face of the case cover [3]. Then make adjustments.

Application
Product

13-1 Torque Limiter, Daily Check
Open the switch box and check every time that oil is replenished or changed.

(1) Limit Switch- Use a tester to see if the limit switch activates normally.
- If it is possible to run the device, force the limit switch to activate while the machine is running to determine whether the torquelimiter works properly.

(2) Dog- Check to determine whether the nut that secures the dog is loose.
- If it is possible to run the device, confirm that, on startup, the dog moves from its stopped condition.

(3) Oil leakage- Check whether oil has leaked into the switch box.
- If oil leaks in, the limit switch may not activate, preventing the torque limiter from working.
- Do not move the position of the limit switch because moving it will change the preset torque value. This will prevent the torquelimiter from working properly.
- A load test is performed and preset torque is adjusted when the device is shipped from the factory.
If the customer disassembles and reassembles the device, the preset torque could change, causing the torque limiter to stop
working properly. This is a source of damage to the device. Therefore, if disassembly or reassembly is required, contact the nearest
accredited maintenance shop.

14. Torque IndicatorCYCLO Drive with Torque Limiter14-1 Torque Indicator(1) Checking the Torque Indicator- The torque indicator is performed zero point adjustment, and the preset torque is adjusted before shipment.
After the reducer has been connected to equipment, if zero is not indicated when the reducer is at rest, it is possible that a small load
is already being applied to the output shaft. Do not readjust to the zero point.
- The relationship between the direction of pointer deflection and slow speed shaft rotation (seen from the slow speed shaft side) isshown below.
1 stage reduction type: pointer opposite direction of the slow speed shaft
2, 3 stage reduction types: pointer in the same direction as the slow speed shaft- The indicator scale displays the load factor, with 100% being the preset torque. Accuracy is within ±10% of the overall load range.

(2) A-Type Torque Indicator
The A-type torque indicator displays load factors of 60 – 100% (depending on the combination of preset torque and reduction ratio, it
displays 50 – 100%).

		2. Replenishment quantities are the same for 2 and 3 stage reduction types.

(4) Replenishment Procedure
Using a grease gun, replenish through grease fittings [2] and [8] (see P95, for C3VM, use [6]). See Table 17-3 for guidelines on quantity.
- If the product has not been operated for one year or longer, make certain to replenish grease before resuming operation.
- Grease while the machine is running to improve grease distribution.
- Replenish grease slowly.
- Contact the nearest authorized maintenance shop concerning a complete grease change.

17-2 Main Unit MaintenanceOil seals have lifetimes. During long use, natural degradation and frictional wear will reduce effectiveness. Reducer operating
conditions and ambient environment will cause lifetime to widely vary. Given normal operation, (uniform load, running 10 hours perday, normal temperature) as a guideline it is recommended to change them every 1 to 3 years. If the sliding surfaces of oil seals or
V-rings show signs of wear or corrosion, replace them with new ones. Because sliding surfaces for oil seals are made of carbon steel,take periodic rust prevention measures regularly not to spread rust on them by applying rustproof oil and so on, if there are exposed
surfaces of steel.
Please consult with the nearest maintenance shop for the replacement of oil seal or V-ring.
