ADJUSTMENTS
-14-
Belt Tracking
The belt tracking is adjusted by lengthening or
shortening a air cylinder pushrod (
Figure 14).
This adjustment is responsible for keeping the
belt in “same-speed” left-to-right motion
during sanding. Your goal is to adjust the
pushrod length until the belt left-and-right
movement takes approximately the same
amount of time.
To adjust the belt tracking, do these steps:
1. Make sure the air flow is set to 57 PSI at
the regulator
.
2.
Put on safety glasses, tie back all loose
clothing, remove jewelry, pull back
sleeves, and tie back long hair so it will
not get caught by the sanding belt.
3. Turn the sander
ON
.
4. Observe the left-to-right motion of the
belt as it moves along the drum while
looking from the front of the sander.
• If the belt tracks faster to the right, but
is slow to track back to the left, loosen
the jam nut and rotate the pushrod to
lengthen the rod until the tracking is
correct. See
Figure 14.
• If the belt tracks faster to the left, but is
slow to track back to the right, loosen
the jam nut and rotate the pushrod to
shorten the rod until the tracking is
correct. See
Figure 14.
5. Make sure the belt tracks left and right at
approximately the same speed.
6.
Keep the sander running, and now
complete the
Belt Oscillation Speed
adjustment as outlined on
page 15
.
KEEP your hands clear of the sanding belt
when making these adjustments!
KEEP loose clothing and
long hair secured and
away from moving
parts.
