5. Confirming condition of the environment:
Confirm that the work site is placed under appropriate conditions conforming to
prescribed precautions.
When sanding a thin steel plate, depending upon the state of the workbench, a loud
noise will be created due to resounding noise from the steel plate being ground. To
eliminate unwanted noise in this instance, place a rubber mat beneath the material to
be ground.
6. Confirming and mounting the wool bonnet and sanding disc
Confirm that the wool bonnet and sanding disc is mounted under the specified condition
and is firmly clamped.
For details, refer to the item “Assembling and Disassembling the Wool Bonnet and
Sanding Disc”.
7. Confirm the lock pin
Confirm that the lock pin is disengaged by pushing lock pin two or three times before
switching the power tool on.
8. Fixing the loop handle
Fix the loop handle with a bolt and a washer to the gear cover.
9. Keep the Hook and Loop fastener clean
Always keep the Hook and Loop fastener of the backing pad and sponge pad (Magic
type) clean. If the Hook and Loop fastener becomes dirty, the sponge pad will separate
possibly from the backing pad and fly off.

Motor speed can be varied as desired by rotating the dial:
It is increased by turning the dial towards “6”, decreased by turning it towards “1” (Fig. 2).
