Changing Drive Belt Position
WARNING: The saw must be turned off and
power disconnected before changing drive
belt positions.
Refer to Figure 9, below.
1. Unplug the electrical cord or open the circuit
breaker in the branch circuit.
2. Open the door on the machine base and the
door on the pulley case.
3. Push up on the motor to pivot the motor
upward and slacken the drive belt.
4. Move the drive belt to the desired pulley
position.
NOTE: Never force the belts to change pulley
location without pivoting the motor to loosen the
motor belt. Failure to do so can cause damage
to the drive mechanism, and accelerate belt
wear and possibly result in belt failure.
