3.Installation of Core Bit◎ Thread Core Bit onto main shaft.

4.Installation of Water Collector◎ Secure Water Collector with Water Collector Fitting.

 WARNING
Be sure to use Water Collector to prevent spattered water from getting into motor
during operation.

5.Arrangement for water disposal◎ Receive water into a bucket by connecting a hose with drain port of water collector orsuck water through drain port using a vacuum cleaner.

－10－

6.Arrangement for water supply◎ Connect a hose between a water source and water cock using Hose Adapter.

 WARNING
Do not stop water supply during operation.

7.Core Drilling WARNING
When drilling a through-hole, take proper measures to provide for protection on theother side where Core Bit penetrates.
1) Turn switch off and plug in.

 WARNING
To prevent accidental starting, make certain that motor switch is in OFF position
before plugging your machine.
2) Turn on a water tap and open water cock slowly, adjusting water flow.

 CAUTION
Allow water to flow at about 2L per minute.
3) Turn switch on to drill with feeding handle. Start drilling by turning feeding handle slowly
until Core Bit in light contact with work surface. While starting to drill, apply lightpressure on feeding handle until drill bit penetrates to 5-10mm depth. Then keep
drilling under uniform pressure.

 WARNING
1. If motor is switched on with Core Bit contacts on the work surface, it causes CoreBit fracturing or Core Drill failure, resting in hazardous accidents.
2. Wait until the rotation of Core Bit increases to the full and then start drilling.
3. Since drill bit often wanders at the starting, turn feeding handle slowly applying lightpressure to prevent bit wandering. Allow water to flow at about 2L per minute.

8.After completion of drilling
1) Remove water hose and Water Collector.
2) Remove Core Bit.
3) Remove Drill Head from Pole Base.
4) Loosen hex. nut and dismount Pole Base.

－11－8. MAINTENANCE AND INSPECTION【1】 Maintenance1) Clean the surface of the machine after using.
Regarding the outer frame of the Drill Head, the part of the gear case is made ofaluminum, and the part of the motor is made of the sturdy synthetic resin.
If gasoline, thinner, petroleum or kerosene are adhered to the outer frame of the Drill
Head, the surface of the Drill Head will be damaged.
When you clean the out frame of the Drill Head, use the dried cloth or the cloth which issoaked with the soapy water.
2) Maintenance for motor.

After entire operation is over, secure Drill Head onto Pole Base, run motor with no-loadand remove dirt and dust from motor interior.

【2】 Regular Servicing
1. Checking of carbon brush1) How to check

Remove Carbon Brush Cap using flathead screw
driver etc., and take Carbon Brush out. Afterreplacement, secure carbon cap.

Carbon Brush2) Item to be checked
If the wearing of the Carbon Brush increases, it will
be caused motor failure. Check it regularly, and if thelength of carbon brush is worn up to the wear limit
line (6mm), replace with new ones.
Keep the Carbon Brush clean for free sliding inbrush holder.

 CAUTION
Use CONSEC specified carbon brush.

2.Checking and adjustment of Drill Carriage Assy.
(In case of combination with □59 Drill Carriage Assy.)◎ Set Drill Head onto Pole Base. While moving
feeding handle, tighten 8 pieces of hex. socket set
screws on Drill Carriage Assy. in good balancewith hex. bar wrench and adjust the gap between
Pole and Drill Carriage Assy.
As for the degree of adjustment from ① side,firsttighten hex. socket set screw till the rattling stops.
As for the degree of adjustment from ② side, firsttighten hex. socket set screw till the rattling stops.
Then loosen them back by one quarter of one
turning.(When core drill is fixed on the floor, drill
head do not slide (fall) down because of its
weight.)①②

 CAUTION
If hex. socket set screw are fastened too tight,
feeding handle gets heavy. When slide plate isworn and starts to rattle, replace it.

3. Checking and adjustment of clutch◎ As Friction Plates wear out, the clutch becomes easy to slip. When this happens,readjust the clutch using clutch adjusting tools.

1) Set the speed change at HI.
2) Remove Hex. Socket Cap Plug 1/8” from Gear Case by Hex. Bar Wrench (5mm).
3) Insert the tip of Clutch Adjusting Pin into the hole, where the plug 1/8” is removed,in parallel with the main shaft. While doing this, slowly turn the Main Shaft by handand further insert Clutch Adjusting Pin till the Main Shaft is locked.
4) Hold Clutch Adjusting Pin by your hand, hang the Spanner 36mm on the Main
Shaft. Using Torque Wrench, fasten the clutch.
