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.

unwanted noise in this instance, place a rubber mat beneath the material to be ground.

Confirm that the sanding disc is mounted under the specified condition and is firmly
clamped.
For details, refer to the item "Assembling and Disassembling the Sanding Disc and Wool

Confirm that the lock pin is disengaged by pushing lock pin two or three times before
switching the power tool on.
