TO REPLACE ThE SANdINg
BELT
1. Lift the upper guard up and tilt it toward the rear of
the machine to expose the drums.
2. Locate the spring-loaded locking clamp (A) on the
right end of the drum. Squeeze the clamp open
and remove the end of the sanding belt (B) from the
drum slot. See Fig. 4.
3. Slowly pull the old sanding belt off the drum.
4. Squeeze the spring-loaded locking clamp on the left
end of the drum and remove the old sanding belt.
5. Squeeze the spring-loaded locking clamp on the
left end of the drum and insert the end of the new
sanding belt approximately 2 inches into the drum
slot.
6. Release the clamp to lock the belt end in place.
7. Rolling the roller by hand, carefully wind the
sanding belt around the drum, making sure to keep
it snug. The edges of the belt should meet without
overlapping.
NOTE: The Dual Drum Sander is designed to achieve coarse and fine sanding in a single pass. Therefore, the
coarser sanding belt should always be installed on the front roller with the finer belt on the rear roller.
TO AdjUST ThE FEEd BELT
TRACkINg
For proper stock feed, both sides of the feed belt must
travel at exactly the same rate. If the feed belt tracks to
the right or left during operation, you will need to adjust
the tension.
NOTE: If the belt tracks to the left, tighten the left
tensioning bolt. If it tracks to the right, tighten the right
tensioning bolt.
1. Locate the feed belt tensioning bolts as shown in
Fig. 5.
2. Turn the sander on and, depending on which
direction the feed belt is tracking, use a 6mm Allen
wrench to tighten either the left or right adjustment
bolt in 1/4-turn increments until the feed belt tracks
evenly.
