OPERATION
PREPARING FOR OPERATION
Your Sander is equipped with its own built-in auxiliary handle
located at the front of the unit, This handle allows for two-
hand use which wilt aid in maintaining complete control and
keeping sanding area level with work piece (See Fig, 1),
Selecting the correct size and type sanding belt is an extremely
important step in achieving a high quality sanded finish,.
Aluminum oxide silicone carbide and other synthetic abrasives
are best for power sanding.
In general, coarse grit will remove the most material and finer
grit will produce best finish in all sanding operations, The
condition of the surface to be sanded will determine which grit
belt will do the job, If the surface is rough, start with a coarse
grit belt sanding until surface is uniform., Medium grit belt may
then be used to remove scratches left by the coarser belt and
finer grit belt used for finishing of the surface. Always con-
tinue sanding with each grit belt until surface is uniform°
INSTALLING AND ADJUSTING SANDING BELT
Be sure power cord is disconnected from power supply.
1. Release tension on belt by pushing the front pulley
squarely against the top or edge of workbench (See Fig. 2).
When the pulley is pushed back it will lock in that position,
allowing slack in the belt so it can be removed. NOTE: Idler
pulley rubbing housing when in the released position,
without sandpaper, does not damage toot operation. The
sanding belt, when assembled, will not allow pulley to
project as far.
2, To install new belt, place belt over both pulleys, making
sure that arrow on inside of belt is pointing in the direction
of rotation which is clockwise when looking into open side
of sander.
3,. Make sure fingers are not in a position to get mashed. Pull
hard on lever (A) until pulley is released and tension is
applied to bett. The lever will move freely at first and then
become harder to pull
4,, To adjust belt, connect sander to power supply,, Stand
sander on end as illustrated (See Fig,, 3), Pull switch trigger
and release immediately while observing tracking of belt.
5o tf belt runs outward, turn tracking screw (B) clockwise and
counterclockwise if belt runs inward. This should be done
until you are sure belt will not come in contact with rub
strip,
6 Start sander and fine adjust the tracking screw (B) until belt
stabilizes. When correctly adjusted, the outer edge of the
belt will be even with outer edge of wear plate,
Note: Belt life will be increased if a few seconds are spent
adjusting the belt tracking properly°
TO OPERATE
Clamp or otherwise secure the work to prevent it moving under
the Sander., With Sander off work, press the trigger switch and
when the motor reaches its maximum speed, lower the Sander
on the work with a slight forward motion Using the main
handle to control the Sander and the front handle only to guide
it, move it slowly over the work, Allowing the Sander to remain
in one place will result in an uneven surface, The Sander was
designed to provide the proper weight on the sand belt and
extra pressure wil! only result in uneven work, stow cutting
from slow belt speed, clogged belts and possible motor burn-
ouL
Use the proper belt when heavy cutting is desired, not heavy
pressure. The importance of this cannot be over-emphasized,
the weight has been built into the tool to give the most ef-
ficient pressure at the proper location.
