Figure 26. Belt tracking adjustment.
Belt Tracking
The belt tracking knob and lever ( Figure 26) stops the
belt from tracking off of the drums and shutting down
the machine. Your goal is to position the belt tracking
lever so the belt tracks in the center of the drums and
the left-and-right belt movement takes a similar amount
of time.
Note: To fine-tune the left-and-right movement you will
adjust Belt Oscillation Speed outlined on Page 23.
To set the belt tracking, do these steps:
1. Complete the Jet Air Flow adjustment on Page 21.
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 belt tracking
knob and push it slightly to the left and retighten
the knob. See Figure 26.
—If the belt tracks faster to the left, but is slow to
track back to the right, loosen the belt tracking
knob and push it slightly to the right and retighten
the knob. See Figure 26.
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 23.
Note: You may have to repeat the belt tracking
adjustment after the Belt Oscillation Speed
adjustment as both of these adjustment affect one
another.
KEEP your hands clear of the sanding belt when
making these adjustments!
KEEP loose clothing and long hair
secured and away from moving parts.
