WARNING:
Before connecting your sander to
power supply source, always check to be sure it
is not in lock-on position (depress and release
switch trigger). Failure to do so could result in
accidental starting of sander resulting in possible
serious injury. Also, do not lock the trigger on
jobs where your sander may need to be stopped
suddenly.
APPLICATIONS
(Use only for the purposes listed below)
Sanding on wood surfaces.
Removing rust from and sanding steel surfaces.
PREPARING FOR OPERATION
For ease of operation, your sander has both a front
handle and rear handle. See Figure 4. This provides
for two-hand operation, which is necessary in order to
maintain proper control of your sander and keep both
hands clear of the sanding disc and sanding area.
When operating your sander, always use both hands.
See Figures 4 and 5.
OPERATION
Flush sanding can be performed with your sander
when the front handle is removed from sander. See
Figure 5. Remove front handle by depressing tab
under front handle while pulling handle up and off of
sander. See Figure 6.
SANDING
Clamp or otherwise secure the work to prevent it from
moving under your sander.
WARNING:
towards the operator causing injury.
Place sander on workpiece so that all of sanding disc
surface is in contact with workpiece. Start your sander
and move it slowly over workpiece making successive
passes in parallel lines, circles, or crosswise
movements. Upon completion of sanding operation,
Fig. 4
turn sander off and wait until sanding disc comes to a
complete stop before removing from workpiece.
WARNING:
when entire surface of sanding disc is in contact
with workpiece. Failure to follow this sanding
procedure could result in loose sanding disc
which could result in possible serious injury.
Do not force. 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 disc 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 as
Fig. 5
the sander's rapid action may remove too much
material, making the surface uneven.
