●Secure the safe scaffold, and do not operate the machine 1.5 m higher than the scaffold.
●When you work at high place, secure the enough scaffold space and secured scaffold.
●When you work at high place, keep any person away under your working area.
5. Be sure to wear the rubber gloves and the rubber shoes.
●Wear the rubber glove and the rubber boot during working due to using the water.
6. Use the proper voltage which is indicated on the nameplate.
●Use the proper voltage which is indicated on the name plate of the Core Drill.
●If you use the Core Drill over the indicated voltage, the rotation of Drill Motor will be high speed which will
cause the injury.
7. Properly connect the plug of the Drill Head and the waterproof connector.
8. Turn off the switch immediately when the abnormal is conrmed.
●When the Core Bit stops or the abnormal sound generates, turn off the switch by pressing drill button.
CAUTION
1. Adjust the Core Drill.
●The drill carriage adjustment is needed in order not to being rattled for the pole base and the drill carriage
of the Core Drill.
2. Away from direct sunlight.
●If the surface temperature of the control box increases more than 40°C, the control function could not oper-
ate properly. If you use the machine outside, away from direct sunlight.
3. Warming up is needed If you use the Core Drill in the cold place.
●The control function will not operate under - 5°C. If you use the machine under such condition, wait for 30
minutes after turning on the power switch and do not start the operation until the inside of the temperature
increases.
※Do not warm up directly by using the stove or the burner.
4. Be careful of cutting.
●When starting to cut to the cutting object, operate manually. After the core drill cuts 5 mm for the cutting
object by the feeding handle of Drill Head, then, operate the automatic feeding.
5. Be careful of not being caught in your body or the power supply cord into the feeding handle of Drill
Head during the operation.

7
CAUTION
6. When you set the Core Drill vertically and the clutch is off, be careful that the Drill Head could fall
down with sliding due to its own weight.
7. Set the load properly and work efciently.
●The proper load of the Drill Motor is different from the condition of cutting object, the size of Core Bit, cut-
ting edge, the horsepower of the Drill Motor, the rotation speed and feeding load etc. The drill load setting
can be judged by the worker such as the sound of the Drill Motor, the condition of the rotation of Core Bit,
feeding speed, and the condition of the camber of the pole base etc. Start from the low load, then set the
proper load.
●When you drill deeply with overload, interference against the drilled core could be generated. Be careful of
load setting.
●In case you set the drill load forcedly, be careful that the machine will get the overload which will cause the
breakdown.
8. Before starting operation, test PRCD in the following procedures.
●Plug power cord and press green ON(RESET) button. Make certain red lamp is on.
●Press blue TEST button and make certain red lamp is off.
●Press green ON(RESET) button again and make certain red lamp is on.
【3】Notes for Usage of the Reinforced Sensor Mode of Automatic Feeding System EHA
WARNING
1. Do not use except the antiseismic reinforcement construction.
●Do not use [Reinforced Sensor Mode], because it might cut or penetrate through except the reinforced
steel (diameter is more than 9mm) such as the electronic piping, telephone wiring piping, water pipe, gas
pipe, resin pipe, steel wire, and other.
2. Use the Core Bit more than 25mm and less than 77mm (3”).
●When you use the Core Bit which is not designated size, the Core Drill might not stop by hitting to the rein-
forced steel during the operation.
3. Do not use the blunt Core Bit.
●The blade edge of the Core Bit plays a role in tentacle of [Reinforced Steel Detector]. If you use the blunt
Core Bit which is caused by clogging, the detection will be difcult and the Core Drill might not stop even
hitting to the reinforced steel during the operation.
4. Depending on the condition of machine and working place, it will be possible to cut the reinforced
steel, so do not being away from the machine during the operation and control the sound of the drill-
ing, the rotation speed of feeding handle shaft and the color of the cutting water etc.

8
CAUTION
1. When interference against drilled core generates during the operation, it will be possible to stop even
though the Core Bit does not hit to the reinforced steel.
● Fix the pole base rmly and adjust the Drill Carriage properly, then start to cut carefully. Cut by manual
feeding until the head of Core Bit cuts the cutting object from 5mm to 10mm.
2. When the Core Bit hits to the reinforced steel during drilling, it stops. But, there will be the scratch by
cutting of the reinforced steel.
●The Automatic Feeding System SIDAF80 (installed reinforced sensor function) detects the load which the
Core Bit cuts the reinforced steel, and stops the rotation of the Core Bit and feeding at one time. There-
fore, there will be the scratch (23mm) on the reinforced steel, but depending on the machines or the
Core Bits, the scratch could be deeper (45mm).
3. When drilling from just before the reinforced steel, there will be the case that the scratch could be
deeper which is caused by cutting to the reinforced steel.
●Regarding drilling deeply, when you stop drilling in order to connect with the tube, then restart. When you
cut from just before the reinforced steel, the cutting depth toward the reinforced steel could be 45 mm.
4. It might be possible to stop except the reinforced steel (such as tree or resin etc).
5. The mode changing (｢Reinforced Sensor Mode｣↔｢Normal Mode｣) can not operate during drilling.
