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.

Tools Needed:

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 (

tion is more than
