G0636X 17" Ultimate Bandsaw
Checking and
Tensioning V-Belts
To ensure optimum power transmission from the
motor to the blade, the V-belts must be in good
condition and operate under proper tension. The
belts 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.

To check the V-belts:
1. DISCONNECT BANDSAW FROM POWER!
2. Open the wheel covers.
3. Note the condition of the V-belts. If the V-
belts are cracked, frayed, or glazed; they
should be replaced.
4. Push the center of the V-belts. Note the
amount of deflection (
Figure 61). If deflec-
tion is more than
3
⁄4", tension the V-belt.

To tension the V-belt:
1. DISCONNECT BANDSAW FROM POWER!
2. Open the wheel covers.
3. Loosen the motor adjustment bolts shown in
Figure 62.

4. Adjust the belt tension:
—If the belt is too loose, turn the tension nut
clockwise to tighten the belts.
—If the belt is too tight, turn the tension nut
counterclockwise to loosen the belts
5. Push the center of the V-belt. If deflection is
approximately
3
⁄4" with moderate pressure,
then the tension is correct. If the deflection is
more than
3
⁄4", repeat Step 4.
6. When the V-belt tension is correct, tighten
the motor adjustment bolts, and close the
wheel covers.
