BELT, ALIGNING PULLEYS, AND
ADJUSTING BELT TENSION
1. Loosen two screws, one of which is shown at (A)
Fig. 17, and remove cutterhead pulley guard (B)
2. Make certain the motor pulley (D) Fig. 18, is aligned
with the cutterhead pulley (C). If necessary, the motor
pulley (D) can be moved in or out on the motor shaft to
provide proper alignment. Then tighten two set screws
(C) Fig. 16.
3. Place the belt in groove of cutterhead pulley (C) Fig.
18, and motor pulley (D). To place belt onto pulleys, lift
up on motor. (Motor mounting hardware should still be
loose.)
4. Correct belt tension is obtained when there is ap-
proximately 1" deflection at the centerspan of the belt
using light finger pressure.
5. If an adjustment is required for belt tension, the
motor can be raised or lowered to obtain the correct belt
tension. Then tighten motor mounting hardware after
tension is applied, making sure alignment of the pulleys
is not disturbed.
6. Replace cutterhead pulley guard (B) Fig. 18, which
was removed in STEP 1 .
