clutch handle is all the way in, or all the way out, so the clutch dogs are in full engagement when the saw is started. 4. Close the pulley case door. 5. Plug the electrical cord into the power source or close the circuit breaker on the branch circuit. Changing Drive Belt Position WARNING: The saw must be turned off and power disconnected before changing drive belt positions. Refer to Figure 11, 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. 5. Release the weight of motor so the motor pivots downward. The weight of the motor will provide adequate belt tension. 6. Plug the electrical cord into the power source or close the circuit breaker on the branch circuit. Changing Pulley-to-Belt Position WARNING: NEVER attempt to change pulley shaft positions while the saw is running. The saw must be turned off and power disconnected any time pulley shaft positions are being changed. 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. With the motor drive belt loose, remove both pulley drive belts. 5. Both of the pulleys are secured to their shafts with two set screws. These are located in the bottoms of the V-grooves on the pulleys. Using a hex wrench, loosen (but do not remove) all four set screws. 6. Pull the pulleys straight off each shaft. 7. Put the lower pulley on the upper shaft and the upper pulley on the lower shaft. 8. Push the upper pulley firmly against the reduction gearbox and tighten the two setscrews which secure it to the shaft. 9. Using a straight edge against the pulley flanges, make certain the bottom pulley is aligned with the upper pulley. Then tighten the two set screws that secure the lower pulley to the shaft. 10. Install the belts as required (refer to Figure 11). 11. Release the weight of motor so the motor Figure 11: Clutch to Pulley Speed Settings pivots downward. The weight of the motor will provide adequate belt tension. 16

4.
Close the pulley case door.
5.
Plug the electrical cord into the power source
or close the circuit breaker on the branch
circuit.
Changing Drive Belt Position
WARNING: The saw must be turned off and
power disconnected before changing drive belt
positions.
Refer to Figure 11, 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.
5.
Release the weight of motor so the motor
pivots downward. The weight of the motor will
provide adequate belt tension.
6.
Plug the electrical cord into the power source
or close the circuit breaker on the branch
circuit.
Changing Pulley-to-Belt Position
WARNING:
NEVER attempt to change pulley
shaft positions while the saw is running. The
saw
must
be
turned
off
and
power
disconnected any time pulley shaft positions
are being changed.
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.
With the motor drive belt loose, remove both

6.
Pull the pulleys straight off each shaft.
7.
Put the lower pulley on the upper shaft and the
upper pulley on the lower shaft.
8.
Push the upper pulley firmly against the
reduction
gearbox
and
tighten
the
two
setscrews which secure it to the shaft.
9.
Using a straight edge against the pulley
flanges, make certain the bottom pulley is
aligned with the upper pulley. Then tighten the
two set screws that secure the lower pulley to
the shaft.
10. Install the belts as required (refer to Figure
11).
