Always wear safety goggles or
safety glasses with side shields when operating
your sander. Failure to do so could result in
foreign objects being thrown into your eyes

LOCK-ON BUTTON
See Figure 2.
Your sander is equipped with a "lock-on" feature,
which is convenient when continuous sanding for
extended periods of time is required. To lock-on,
depress the switch trigger, push in and hold the lock-
on button located on the side of the handle, then
release switch trigger. Release lock-on button and
your sander will continue running. To release the
lock, depress switch trigger and release it.
If you have the "lock-on" feature engaged during use
and your sander becomes disconnected from power
supply, disengage the "lock-on" feature immediately.
WARNING:
Your sander should never be
connected to power supply when you are
assembling parts, making adjustments, installing
or removing sandpaper, when cleaning, or when
not in use. Disconnecting your sander will
prevent accidental starting that could cause
serious injury.
WARNING:
Do not wear loose clothing or
jewelry when operating sander. They could get
caught in moving parts causing serious injury.

SANDING DISC SELECTION
Selecting the correct size grit and type sanding disc is
an extremely important step in achieving a high
quality sanded finish. Aluminum oxide, silicon carbide,
and other synthetic abrasives are best for power
sanding. Natural abrasives, such as flint and garnet
are too soft for economical use in power sanding.
In general, coarse grit will remove the most material
and finer grit will produce the best finish in all sanding
operations. The condition of the surface to be sanded
will determine which grit will do the job. If the surface
is rough, start with a coarse grit and sand until the
surface is uniform. Medium grit may then be used to
remove scratches left by the coarser grit and finer grit
used for finishing of the surface. Always continue
sanding with each grit until surface is uniform.
TO ATTACH SANDING DISC
See Figure 3.
Unplug your sander.
WARNING:
Failure to unplug your sander could
result in accidental starting causing serious
injury.
Carefully peel adhesive backing from new
sanding disc.
Align holes in sanding disc with holes in backing
pad, then carefully press sticky side of disc
against pad as tight as possible. NOTE: Holes in
sanding disc must line up with holes in the
backing pad in order for the dustless feature of
your sander to function properly.
