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

Damaged cord must be replaced
or repaired.

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

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