4.
Loosen the motor mount fasteners shown in
Figure 59.
5.
Shift motor horizontally as needed to align
motor pulley with cutterhead pulley.
6.
Tighten motor mount fasteners. V-belt
should be parallel and aligned as shown in
Figure 58.
7.
Re-install fence assembly, rear access panel,
and V-belt guard.
Pulley Alignment
Pulley alignment is another important factor in
power transmission and belt life. The pulleys
should be parallel to each other and in the same
plane (coplaner) for optimum performance.
Each pulley can be adjusted by loosening the
motor mount fasteners, sliding the motor in or
out, and retightening the fasteners to lock the
motor pulley in place.
