Cautions when in use.

⚠ WARNING


Do not disassemble or alter the unit.
Do not disassemble the unit including a pump except for such components as oil
feeding plug as instructed for working. Especially, do not change pressure set at a relief
valve. Otherwise, it will cause insufficient pressing force, damage of press frame orworking tools.



Avoid any condition which could create an electrical hazard.
Do not pull out power supply plug with a wet hand. Use a grounded outlet or a plug
adaptor with a grounding attachment in order to protect the operator from electric
shock.
Do not operate the unit hard by an electric welder or on materials or machine parts
which are grounded.



Recommend to use Model UP-35RH-FL or UP-45SVG-FL hydraulic pump.
These pump units are rated at 68.6Mpa(700 kgf/㎠) pressure. Other makes withdifferent specifications will cause too much or too little pressing force resulting indamage of a frame or tools.

⚠ CAUTION

Do not work beyond capacity.
Processing beyond capacity will result in defectiveness.

Processing must be done alone.
It is dangerous to work together with several persons.



Voltage of hydraulic pumps will be AC110V or 220V 50/ 60 Hz single phase.
Your line voltage must be the same as the voltage your pump is wire for (e.g. 220 volt
pump plugged into 220/230 volt power source.). Use on wrong voltage, especiallyplugged into lowered voltage will cause motor burning or heating. Be careful on voltage
drop when used with generators.

Disconnect the power supply, keeping a grip on a power plug before performing
repairs or maintenance.

Extension cords of 1.25 ㎟ or sufficient gauge and 10M length must be used to avoid
voltage drop or damage of the solenoid valves and electric motors.

3. PREPARATION BEFORE WORKING
Read and carefully follow these instructions. Most problems with new equipment are caused
by improper operation or installation.
3-1) Confirmation of the products
Carefully inspect the machine upon arrival. The carrier, not the manufacture, is responsible
for any damage resulting from shipment.
3-2) Confirmation of pump voltage
Voltage of a motor-driven hydraulic pump is AC 110V or 220V (50/60Hz) single phase. Usea grounded outlet or a plug adaptor with a grounding attachment to protect the operator fromelectric shock.
3-3) Confirmation of working oil. When working efficiency has been lowered, there issomething abnormal about the pump unit.
In case of lowering of working efficiency and/or happening of anything abnormal, one of thepossible causes is considered shortage of oil quantity. The pump has been shipped with oil in
the reservoir. Fulfil the following steps and confirm if oil volume in the reservoir is sufficient.
① Confirm if the cylinder pistons have been retracted fully.
② Disconnect the power supply.
③ Erect the pump (UP-35RH-FL) oil tank down as sketched next page.
④ Turn the oil feeding plug counter-clockwise with a screwdriver and remove the plug. Be
careful you do not miss an O-ring.
⑤ Clean the oil gauge of the removed the plug with a cloth and put it in again, without
screwing in, to see an oil level.
⑥ If oil level is high up to the marking of the gauge, it is O.K. But, if the oil has got low
replenish oil.
⑦ After normal oil quantity has been confirmed, replace the oil feeding plug by screwing in.
Do not overtighten plug to avoid damage of the O-ring.

4. HOW TO OPERATEa) Bring the change -over lever down in a direction you want to work (one is V notching sideand the other is bending side.). For example, If the lever is brought down in bending side
direction, you are ready to operate the cylinder of the bending unit.

7b) Depress “A” button of the pendant switch to run the pump motor and go down the upper
die for forming. If the button is released, the motor stops and the die also stops at that
position.
c) After processing ( cutting or bending) is over, depress “B” button to retract the upper die.
The standard type pump does not allow the die to stop on the way at retracting stroke.
Contact us for such specially designed pumps.

5. MAINTENANCE
5-1) Hydraulic working oila)Type
Use only an approved, high-grade hydraulic oil (ISO 32 cSt).

b)

Temperature
Proper temperature available is max. 55℃. If color of temperature seal fitted on the oiltank changes, it indicates that oil temperature rises over 55℃. At that time, stop working
until temperature goes down properly. Even if “55” marking disappears, do not operate
the pump for the time being.

8c)Exchange of hydraulic oil

The frequency of oil changes will depend upon the general working conditions, severity ofuse , and overall cleanliness and care given the pump. One year or 300 hours (working time)of use is considered as a standard oil change interval. Change oil as follows;① Retract the cylinder fully and disconnect the power supply.
② Disconnect the quick coupler.
③ Erect the pump (UP-35RH-FL) oil tank down.
④ Turn the oil feeding plug counter-clockwise and remove it. Be careful you do not missthe O-Ring.
⑤ Remove the oil fully. If necessary, clean the inside of the reservoir and fill with a suitableflushing oil. Rinse the filter clean.
⑥ Refill the reservoir with new oil. The proper oil level is the same as the marking of the oillevel gauge (oil feeding plug). Refer to [3-3 Confirmation of working oil, Page [5]⑦ Screw the oil feeding plug in. be careful about the O-Ring and overtightening.
⑧ Clean all the areas around the oil feeding plug and oil port of the pump. After refilling,
air may accumulate in the pump or hydraulic system. This air will cause the cylinders to
respond in an unstable or slow manner. Remove this air, referring to [5-4 Bleeding air
from the system, Page 9]5-2) High pressure hose
Since high pressure hoses might have been deteriorated after long use, it is recommended that
hoses will be exchanged every two years. Required hoses are rated at 68.6Mpa (700 kgf/㎠)
or over and with fitting threads of PT3/8.
Avoid any condition which could damage the hose and impair the pump’s performance . Neverallow the hose to kink, twist or bend so tightly that the oil flow within the hose is blocked or
restricted. Periodically inspect the hoses for signs of wear. Never use a defective hose withany pressurized equipment.
Apply two layers of Teflon tape to the external threads to seal hydraulic connections. Tighten
the connections in accordance with the following tightening torque table. Do not overtighten
the connections. When reconnected, firstly remove surviving tapes left on the threads, whichshould not enter into hydraulic system.

100 – 110 (6.0 – 7.0 )5-3) Couplers
Recommend to use our standard Nittoh couplers. If it is not available, choose 70Mpa hydrauliccouplers for both pump side and FN30 side. Couplers must be the same type.
5-4) Bleeding air from the system
After changes of hydraulic oil and/or hydraulic hoses, air may accumulate in the system if thereservoir oil level had been permitted to get too low. This air will cause the cylinder to respondin an unstable or slow manner or the pump to build up required pressure. In this case, takethe following steps.
① Disconnect the coupler.
② Check oil quantity. Refer to [3-3 Confirmation of working oil, Page 5].
③ Even if a trouble has been solved by adding oil to the reservoir, erect the pump (UP35RH-FL) the oil tank down as sketched and depress both “A“ and “B” button of thependant switch intermittently and alternately.

105-5) Substitution of cutting blades and re-polishing
In case cutting sharpness of V notching lower blades have been dull, sharpness can be restored
one time by rotation of the blades as per the arrows as sketched below. The bladed which havebeen rotated one time are no longer used and must be exchanged.
There is the possibility that sharpness of V notching upper blades can be restored by repolishing. Contact us if desired.
