Tensioning/Replacing
V-Belt
4. Check V-belt tension by applying moderate pressure
between pulleys (see Figure 84).
— If V-belt deflection is approximately
1
⁄4", belt
is correctly tensioned and no adjustment is
necessary.
— If deflection is not approximately
1
⁄4", V-belt is not
correctly tensioned. Proceed to Step 5.
To ensure optimum power transmission from the motor
to the blade, the V-belt must be properly tensioned,
and free of cracks, fraying, and wear. Belt tension and
condition should be checked at least every 3 months—
more often if the bandsaw is used daily.

To check/adjust V-belt tension, do these steps:
1. DISCONNECT MACHINE FROM POWER!
2. Open lower wheel cover.
3. Inspect V-belt; if it is cracked, frayed, or glazed,
replace it (refer to Replacing V-Belt on Page 64).

5. Loosen both motor mount cap screws (see
Figure 85).
6. Apply pressure against motor to tension belt.
7. While applying pressure, retighten motor cap screws
to secure adjustment.
8. Re-check belt tension.
MAKE SURE that your machine is
