TRACKING ABRASIVE BELT
Refer to Figure 9, page 7.
• Test the tracking. Plug in power cord. Turn switch ON
and immediately OFF. If the abrasive belt is centered
on wheels and did not move to the right or left, it is
tracking properly. If the belt moved to the right or left,
adjustment is necessary.
• To adjust the tracking wheel, loosen the locking nut
on adjusting bolt. Use a 4mm hex wrench to turn
adjusting bolt.
