Tensioning/
Replacing V-Belts
To ensure optimum power transfer from the motor
to the blade, the V-belts must be in good condition
and operate under proper tension.
Check V-belt tension at least once every three
months—more often if the bandsaw is used daily.
V-belts stretch with use and must be periodi-
cally retensioned. Replace the V-belts if they are
cracked, frayed, or badly worn. Refer to Figure 61
to identify V-belt locations.

DISCONNECT BANDSAW FROM POWER!
2.
Remove the rear motor access panel.

Push the center of each V-belt with moderate
force. When tensioned correctly, there should

overtighten the belts or the bearings will wear
prematurely.
Speed Hub Belts
Rotate the speed handwheel left or right until the
belts are loose. Roll the belts off the pulleys to
replace them. (If you get them mixed up when
replacing, the belt on left is the larger of the two.)
Note: When the machine is started, the belts will
automatically adjust to the correct tension.
Sprocket Drive Belt
Loosen the tensioner hex bolt, then loosen the
three intermediate pulley retaining cap screws so
the belt is loose. Replace the sprocket drive belt.
Retighten the intermediate hub and adjust the
tensioner hub to tension the new belt.
Air Pump Belt
Loosen the pump mounting bolts, replace the belt
and tension it by positioning the air pump, then
tighten the mounting bolts.
Note: Make sure that when tightened, the pump
pulley is aligned with the motor drive pulley.
