ADJUSTMENTS

Feed Belt Tension
The feed belt tension has been set at the facto-
ry and should not need to be adjusted when the
machine is new; however, if at any point you
notice that your feed belt is slipping on the
rollers, it should be tensioned.
Tension the
feed belt as follows:
1.
Unplug the sander from the power source!
2.
Position the emergency brake plate up as
far as it will go, so that it is out of the way
of the tension screws (one is shown in
Figure 24
). The back feed roller is not
adjustable, and therefore, no adjustment
screws are located at the back of the
sander.
3.
Turn the adjustment bolt clockwise to
increase the tension and turn it counter-
clockwise to decrease the tension. Adjust
each side evenly so that the tracking does
not become misaligned.
4.
When the tension is correct, run the belt for
at least three minutes to check the tracking
before resuming sanding operations.
Feed Belt Tracking
If you notice that the feed belt is tracking more
to one side, turn the feed belt
OFF
immediately
and adjust the tracking. The belt tracking is
adjusted by using the same adjustment screws
that were used during feed belt tensioning.
Tension the feed belt tracking as follows:
1.
Use the adjustment screws to position the
feed belt roller evenly on each side.
Measure the roller shaft location in the
mounting brackets with a caliper or fine
ruler to get each side even.
2.
Run the feed belt for at least three minutes
to determine if the tracking is correct. If
the belt does not track evenly, make small
adjustments to the side opposite of the belt
travel and repeat this step until it tracks
evenly.
