V-Belt Tension
To ensure optimum power transmission from the
motor to the blade, the V-belt must be in good
condition and operate under proper tension.
V-belt tension should be checked at least every
month—more often if the bandsaw is used daily. If
the belt shows signs of cracks, fraying, and exces-
sive wear, replace it as instructed in
Replacing
V-Belt on Page 48.
Checking V-Belt Tension
1. DISCONNECT BANDSAW FROM POWER!
2. Open the lower wheel cover.
3. The V-belt is properly tensioned if there is
approximately 1 ⁄

" deflection of the V-belt
when you apply moderate pressure to it
between the pulleys (see the illustration in the
following figure).
— If the V-belt is not properly tensioned,
perform the following
