SAFETY
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]
Before start drilling, make sure the Carriage Block (Feed House) is properly adjusted and that the tool is in
line with the Drill Stand. 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.
[7]
Maintain tools carefully. Keep handles dry, clean, and fee 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.
[8]
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] CIRCUIT PROTECTOR for more details.)
