1.3 IMPORTANT OPERATING INSTRUCTIONS
WARNING!!
Following instructions are essential measures that the operators must take.
[1]
Ensure that the adequate water is supplied to the Core-Bit during operation, unless Dry-Bit is used. Do not allow
excessive heat to be generated at segments of the Core-Bit. The overheat may result in breakage of the segments, and
may lead to injury of the operator.
[2]
Do not block the cooling air inlets of the Drill Motor. If the inlets are blocked, the cooling might be insufficient and the Drill
Motor could burn.
[3]
Do not let water get into the Drill Motor. The water in the motor can decrease the insulation capacity and the Drill Motor
could burn out. Also, do not expose the Drill Motor to rain or snow.
[4]
Do not push the Core-Bit too hard. Too much pressure on the Core-Bit will decrease the drilling capacity and might burn
the Drill Motor.
[5]
When using with Drill Stand, make sure the Carriage Block (Feed House) is properly adjusted and that the tool is in line
with the Drill Stand, before start drilling. When you adjust it, make sure the plug is disconnected from the main power
source.
[6]
Check for damaged parts. Inspect guards and other parts before use. Check for misalignment, binding of moving parts,
improper mounting, broken parts, and any other conditions that may affect operation. If abnormal noise or vibration
occurs, turn off the machine immediately and have the problem corrected before further use. Do not use a damaged
machine as it is. Tag damaged machine “DO NOT USE” until repaired
or replaced by an authorized service center unless
otherwise indicated in this manual.
[7]
Maintain tools carefully. Keep handle and grip dry, clean, and free from oil and grease. Keep cutting edges sharp and
clean. Follow instructions for lubricating and changing accessories. Periodically inspect the machine’s cord for damage.
Have damaged parts repaired or replaced by authorized service center.
If the switch does not turn on it on and off, do not
use the tool. Have defective switches replaced by an authorized service center.
[8]
When the tool is used outdoors, use only extension cord intended use for outdoors use and so marked.
[9]
When not in use, store the machine in a dry secured place. Keep out of reach of children.
CAUTION!
[1]
Maintain Labels and Name Plates. These carry important information. If unreadable or missing, contact Shibuya’s
authorized service center.

TROUBLE SHOOTING – WHEN YOUR CORE-BIT IS JAMMED
Never turn on the switch till the Core-Bit is released if your Core-Bit is jammed during operation, because it will lead to
fatal damage of electrical parts in the Drill Motor. (Refer to 12.0 TROUBLESHOOTING for more details.)
[3]
TROUBLE SHOOTING – WHEN CIRCUIT PROTECTOR TRIPS FREQUENTLY
Wait until temperature of bi-metal in the Circuit Protector is cooled down. If you try to continue drilling it may result in the
burn of the Circuit Protector. (Refer to 12.0 TROUBLESHOOTING and 6.0[1] OVERLOAD SWITCH & CIRCUIT
PROTECTOR for more details.)
