3. Use a 9/16” socket with an extension (not supplied).
Place it in one of the two holes where the hole plugs were
removed. Loosen one hex bolt, then the other to relieve
tension on the motor. (One is shown at (D) Fig. 26). Apply
upward pressure on the motor (located under the machine)
to relieve tension on the belt. Replace or change the belt
positions on the pulleys. IMPORTANT: When the belt is on
the inner pulleys (F) Fig. 26, the sanding drum speed is 3300
SFM. When the belt is positioned on the outer pulleys (G)
Fig. 27, drum speed is 2210 SFM. NOTE: Position the poly-
v drive belt on the pulleys correctly to provide maximum
performance with minimal belt wear.
4. After the belt (E) Fig. 28 has been repositioned or
replaced on the pulleys, apply downward pressure on the
motor and tighten the two hex head bolts (D) (loosened in
STEP 3).
5. Use light finger pressure on the belt (E) Fig. 28 midway
between pulleys to check for proper tension. A deflection of
approximately 3/16" is correct.
6. Replace the hole plugs (B) Fig. 25.
