ADJUSTING YOUR CUTTING SPEED
WARNING: Disconnect machine from the power source!
Never make adjustments with the machine running! Fail-
ure to comply may cause serious injury!
1. Open the lower cover. Slacken the drive belt by unscrewing the
hex bolt used to fasten the motor in place on the backside of the
lower housing. This will allow the motor to freely move about.
2. Slide the motor towards the middle of the bandsaw. This will
loosen the spindles of the lower housing enough to adjust the belt
from one speed to another.
3. Place drive belt on the desired combination of wheel and motor
pulleys (refer to diagram, Fig. Q), making sure the grooved surface
of the belt is on the inside.
4. Pull the motor back into its original position, making sure that
the speed belt is properly taut, moderate finger pressure on the belt
between the two pulleys causing a 1/2" deflection. Fasten the hex
bolt again to hold the motor in place.
REPLACING THE DRIVE BELT (Figure 13)
WARNING: Disconnect machine from the power source!
Never make adjustments with the machine running! Failure to
comply may cause serious injury!
1. Unplug the machine from the power source.
2. Open the upper and lower doors.
3. Remove the saw blade as described in Changing Blades section.
4. Remove tension on the drive belt (D) by loosening the screw (13mm
wrench required) on the back of the cabinet that secures the motor.
(Fig. R)
5. Using snap ring pliers, remove the snap ring (E) that secures the lower wheel (B) to the shaft (A).
6. Slide the lower wheel assembly off the shaft (A) which will dislodge the belt (D) and discard the old belt.
7. Place the new belt onto the lower wheel pulley.
8. Reinstall lower wheel assembly by sliding it back onto the shaft (A).
9. Replace snap ring (E).
10. Place the new belt (D) partially around the motor pulley (C) to get it started, then turn the wheel (B) by hand
until the belt (D) is completely seated on the motor pulley (C).
11. Push the motor down to add tension to the belt (E). The belt is properly tensioned when moderate finger
pressure on the belt between the two pulleys causes a 1/2" deflection.
12. Tighten the screw on the back of the cabinet that secures the motor.
Re-install the blade as described in Changing Blades section.
