Ensure that the power source to be utilized conforms to the power source
requirements specified on the product nameplate.

receptacle while the switch is in the ON position, the power tool will start operating
immediately and can cause serious injury.

3. Extension cord

When the work area is far away from the power source, use an extension cord of
sufficient thickness and rated capacity. The extension cord should be kept as
short as practicable.

If the receptacle only loosely accepts the plug, the receptacle must be repaired.
Contact a licensed electrician to make appropriate repairs.
If such a fautly receptacle is used, it may cause overheating, resulting in a serious
hazard.

5. Confirming condition of the environment

Confirm that the work site is placed under appropriate conditions conforming to
prescribed precautions.
