○ Kickback Protection
The kickback protection feature cuts off the power
to the motor and stops the power tool in the event of
a sudden drop in the rotational speed of the wheel
during operation (for example, if the wheel locks
during cutting operation, etc.).
○ 0 Voltage Re-start Protection
The 0 voltage restart protection feature prevents the
power tool from restarting after the power has been
temporarily cut off during operation.
○ Overload Protection
The overload protection feature shuts off the power
to the motor in the event of overloading of the motor
or a conspicuous reduction in rotational speed during
operation.

power outage or unplugging during operation in order
to avoid unexpected accident.
NOTE
The grinder is equipped with a rotational speed control
circuit. The rotational speed may fl uctuate slightly due
to the conditions of use and working voltage.
3. Extension cord
When the work area is far away from the power
source, use an extension cord of suffi cient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
WARNING
Damaged cord must be replaced
or repaired.
4. Check the receptacle
If the receptacle only loosely accepts the plug, the

electrician to make appropriate repairs.
If such a faulty receptacle is used, it may cause
overheating, resulting in a serious hazard.
5. Check your work environment
Ensure the following before operation;
○ No fl ammable gas, liquid, or object at worksite.
