V-Belt pulley
Alignment
periodically check the V-belt for signs of wear. if
you notice one side of the belt is worn more than
the other, the belt pulleys are likely misaligned.
the correct alignment of the motor and lower
wheel pulleys help to ensure proper power trans-
mission and reduce V-belt heat and wear during
operation.
To align the V-belt pulleys:
1. disConneCt FroM poWer!
2. remove the right side base cover and use a
straightedge across both pulleys, as shown in
figure 52, to check the pulley alignment.
—if the pulleys are aligned, no further action
is necessary.
—if they are not aligned, continue with Step
3.
3. loosen the motor pulley set screw, align the
motor pulley with the gearbox pulley, then
tighten the set screw.
4. replace the right side base cover.

Replacing V-Belt
tensioning/replacing v-belts
to ensure optimum power transfer from the motor
to the blade without slipping, the V-belt must be in
good condition and operate under proper tension.
Blade tension is maintained by the weight of the
motor and requires no adjustments. Check the
condition of the belt at least every three months
for signs of wear, slipping, or oiliness—check
more often if the bandsaw is used daily.
To check/replace the V-belt:
1. disConneCt BAndsAW FroM poWer!
2. remove the right side base cover.
3. Make sure the motor and lower wheel pulleys
are correctly aligned.
4. inspect the V-belt for any signs of glazing,
cracking, side wear, fraying, or any other
excessive wear.
—if the V-belt is in good shape, no further
action is required. replace the right side
base cover. if not, continue below.
5. lift up on the motor to release pressure from
the belt, then roll the belt off the motor pulley.
remove the belt.
6. place the new belt over the gearbox pulley.
lift the motor and roll the belt over the motor
pulley, then carefully lower the motor.
7. replace the right side base cover.
