Pulley Alignment
Pulley alignment is another important factor in power
transmission and belt life. The pulleys should be par-
allel to each other and in the same plane (coplanar)
for optimum performance.
Each pulley can be adjusted by loosening the motor
mount bolts, sliding the motor in or out, and retight-
ening the fasteners to lock the motor pulley in place.
To align the pulleys:
1. DISCONNECT MACHINE FROM POWER!
2. Open the back cover and remove the belt guard.
3. Visually check the alignment of the two pulleys
to make sure that they are aligned and that the
V-belts are straight up and down (see Figure
75).
— If the pulleys are aligned, go to Step 8.
— If the pulleys are NOT aligned, do Steps 4–7.

5. Shift the motor horizontally as needed to align
the motor pulley with the cutterhead pulley.
6. Tighten the motor mount bolts.
7. Close the back cover and reinstall the belt guard.
