SERVICE
Belt Service
To ensure optimum power transmission from the motor to
the blade, the belt must be in good condition and operate
under proper tension. The belt should be checked for
cracks, fraying, and wear. Belt tension should be checked
at least every 3 months—more often if the bandsaw is
used daily.
Checking Belt
1. DISCONNECT BANDSAW FROM POWER!
2. Open the lower wheel cover.
3. Note the condition of the belt. If the belt is cracked,
frayed, or glazed, it should be replaced.
4. Press the belt with moderate pressure midway
between the pulleys. The deflection should be
approximately
1
⁄4", as illustrated in Figure 52.
— If the deflection is not approximately
1
⁄4",
continue with the next procedure to properly
tension the belt.
Adjusting Belt Tension
Tools Needed Qty

To tension the belt, do these steps:
1. DISCONNECT BANDSAW FROM POWER!
2. Open the lower wheel cover and loosen the motor
mount bolts (adjustment and hinge) shown in
Figure 53.
4. Move the motor so that the motor adjustment bolt
slides to the left-hand side (facing bandsaw front) of
the adjustment slot.
5. Hold the motor in position with one hand and tighten
the motor adjustment bolt with the other hand.
6. Press the center of the belt. If deflection is
approximately
1
⁄4" with moderate pressure from your
thumb or finger, then the tension is correct. If the
deflection is more than
1
⁄4", repeat Steps 4-6.
7. When the belt tension is correct, tighten the motor
hinge bolt and close the lower wheel cover.
