ADJUSTMENTS
Make sure that your
machine is unplugged
during any adjustment
procedures unless
instructed to do differ-
ent! If this warning is
ignored, serious person-
al injury may occur!
General Information
The adjustments in this section have been fac-
tory set and generally do not need to be per-
formed when you first receive your sander; how-
ever, we suggest that you become familiar with
these adjustments before operating your
sander. This information will help you under-
stand the machine better and will prepare you
for the types of adjustments that can be made
in the event of any troubleshooting.
Oscillation Timing
When adjusting the oscillation action of the
sander, the first thing you should do is adjust
the balance of the sanding belt side-to-side
movement. When the timing is right, the belt
will take the same amount of time to move in
one direction, as it moved in the other direc-
tion.
Time the oscillation as follows:
1.
With the sanding belt installed and properly
tensioned, open both access doors on the
upper part of the sander, then turn the
sanding belt
ON
and determine the oscilla-
tion timing status.
•
If the oscillation timing is correct
the sand-
ing belt will move back and forth evenly,
and no further adjustments to the timing
will be needed.
•
If the oscillation is incorrect
, the belt will
move faster to one side, then slower to the
other—follow
step 4
to adjust; or if the belt
comes off the rollers and immediately stops
the sander—follow
steps 3-4
to adjust.
3.
If the belt moves too far to one side and
stops the sander, then re-adjust the timing
control knob (shown in
Figure 15
) approxi-
Always wear safety glass-
es during operations.
Serious injury may occur
if this is warning is ig-
nored!
Always keep loose
clothing and long hair
secured and away from
moving parts.
