Belt Tracking Adjustment
The Belt Tracking Adjustment is a fine adjustment
procedure. The Motor Mount Tracking Adjustment
(following section) is a course adjustment.
To adjust the belt tracking:
1. Disconnect the machine from the power
source.
2. Push the belt by hand from left to right (the
direction indicated top of the platen) and
observe the belt’s position on the rollers. The
oscillating movement of the belt is by design.
Observe the belt's range of movement from its
highest to lowest position. The edges of the
belt should not have a tendency to move
above or below the edges of the rollers.
If adjustment is still necessary:
3. Insert the round shaft of the belt tracking tool
(provided) into the micro adjust lock nut (A)
and turn away from you to loosen.
4. Turn the micro adjusting screw (B) in 1/4 turn
increments until the belt tracks evenly on the
rollers when rotated by hand.
Tip: Moving the belt tracking tool away from
you raises the belt on the drum and towards
you lowers the belt on the drum.
5. Tighten the micro adjusting nut (A).

6. Connect the machine to power.
7. Turn on the power to the machine and observe
the belt’s up and down range of movement.
Adjustment is correct when the edges of the
belt do not move above or below the edges of
the rollers.
8. When adjustment is complete, tighten the micro
adjust lock n ut (A).
If the tracking cannot be corrected go to the Motor
Mount Tracking Adjustment section (next page).
