OPERATION
PREPARING FOR OPERATION
For ease of operation, this tool has a front auxiliary handle
and rear handle. See Figure I. This provides for two-hand
operation, which is necessary in order to maintain proper
control and keep both hands clear of the sanding disc and
sanding area. When operating your sander/polisher, always
use both hands. Check the auxiliary handle before each use
and make sure the handle bolt is tight against the housing.
SANDING
Clamp or otherwise secure the work to prevent it from moving
under your sander/polisher. Secure small workpieces in a
vise or use clamps to secure them to a workbench.
WARNING:
Unsecured work could be thrown towards the operator
causing injury.
i
Hold the tool in front and away from you, keeping it clear of the
workpiece. Start the tool by depressing the switch trigger and
letting the motor build to its maximum speed. Gradually lower
sander/polisher to the workpiece at a slight 5° to 8° angle. See
Figure 5.
DO NOT ATTEMPT TO HOLD THE SANDING DISC FLAT
ON THE WORKPIECE.
Always keep the tool in motion moving over the work, allowing
it to operate freely without unnecessary pressure. The weight
of the unit supplies adequate pressure, so let the sanding disc
and sander do the work. Applying additional pressure only
slows the motor, rapidly wears sanding discs and greatly
reduces sander speed. Excessive pressure will overload the
motor causing possible damage from motor overheating and
can result in inferior work. Any finish or resin on wood may
soften from the frictional heat. Do not allow sanding on one
spot too long. Sanding in one spot too long will cause
uneven sanding and gouging of the work.

Upon completion of a sanding operation, lift tool away
from work surface before turning off.
, WARNING:
Sanding disc must come to a complete stop before setting
tool down on workbench. Failure to do so can cause the
tool to be thrown from workbench because of sanding
disc rotation. This could result in damage to the tool or
possible serious injury to the operator.

, WARNING:
Keep a firm grip on the tool with both hands at all times.
Failure to do so could result in loss of control leading to
possible serious injury.
