To ensure optimum power transfer from the motor
to the blade, the belt must be in good condition
and operate under proper tension. The belt should
be replaced if has for cracks, fraying, or excessive
wear. Belt tension should be checked at least
every 3 months—more often if the bandsaw is
used daily.
To check the belt:
1. DISCONNECT BANDSAW FROM POWER!
2. Open the lower wheel cover.
3. Check the belt tension. When tensioned
correctly, the middle of the belt will deflect
approximately
1
⁄4" when pushed with moder-
ate pressure (see Figure 42).
To tension the belt:
1. DISCONNECT BANDSAW FROM POWER!
2. Open the lower wheel cover.
3. Loosen the motor mount bolts shown in
Figure 43.

4. Move the body of the motor so the motor
adjustment bolt slides to the left-hand side of
the adjustment slot.
5. Hold the motor in position with one hand and
tighten the motor adjustment bolt with the
other hand.
6. Push 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 3–6.
7. When the belt tension is correct, tighten the
motor hinge bolt and close the lower wheel
cover.

4. Note the condition of the belt. If the belt
is cracked, frayed, or glazed; it should be
replaced as soon as convenient.
