Checking/Adjusting
Belt Tension
To ensure optimum power transmission from the
motor to the blade, the belt must be in good condi-
tion and operate under proper tension.
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
Belt on Page 43.
Checking Belt Tension
1. DISCONNECT MACHINE FROM POWER!
2. Open lower wheel cover.
3. Check belt condition and deflection. The belt
is properly tensioned if there is approximately
1
⁄
4
" deflection. Deflection is checked by push-
ing belt with moderate pressure, as shown in
Figure 50, and noting how much it moves.
— If the belt is not properly tensioned, per-
form the
Tensioning Belt procedure.
