CHANGING SPINDLE SPEED RANGE
TURN OFF AND UNPLUG THE MACHINE FROM THE POWER SOURCE BEFORE OPENING THE BELT GUARD OR BEFORE PERFORMING
ANY MAINTENANCE OR ADJUSTMENTS.
1. To access the belt and pulleys, loosen the belt
guard lock knob A and open the belt guard locat-
ed on the headstock.
4. Set the belt by hand to the required pulley posi-
tion (High/Low), D.
5. Push the belt tension release lever C forward to re-
tension the belt, and then tighten the belt tension
locking lever B.
6. To verify the belt positioning and ensure the belt
will run smooth on the pulleys; rotate the flywheel E
by hand to turn the spindle while observing the belt
movement. If the belt moves smoothly close the belt
guard – if the belt wobbles between the pulleys
repeat steps 2-5 as needed.
