PRIOR TO OPERATION

1. Power source
Ensure that the power source to be utilized conforms to the power requirements specified
on the name plate of this demolition hammer.

thickness and rated capacity. The extension cord should be kept as short as practicable.

the nearest authorized service center for repair service.
If such a faulty receptacle is used, it may cause overheating, resulting in a serious
hazard.

prescribed precautions.
