LOWER BLADE GUIDES
Note: The lower blade guides and support bearings
should always be adjusted after the blade is tensioned,
tracking is adjusted, and the upper blade guides and
upper support bearings are properly adjusted.
1. Loosen both front hex socket screws with a hex
wrench and move the bearings as close to the sides
of the blade as possible without pinching it.
2. Using the feeler gauge, measure the spaces between
the guide and the blade. Adjust to 0.02”.
3. Tighten the hex screws and loosen the side hex sock-
et screw . Move the guide support bracket in or out
until the guides are at least 1/32” behind the saw teeth.
Tighten the screw.
LOWER SUPPORT BEARING
1. Loosen the bearing hex socket screw with the hex
wrench.
2. Move the blade support bearing shaft in or out until
the support bearing is 1/64” behind the saw blade.
3. Tighten the bearing hex socket screw .
PULLEY ALIGNMENT
Note: The pulley alignment has been pre-set and verified
at the factory and should not need re-adjustment. If
adjustment is needed or the belt needs replacing:
1. Place a straight edge in the front groove of both pul-
leys, behind the blade wheel.
2. Turn the set screw in the side of the motor pulley to
loosen the pulley on the shaft.
3. Adjust the pulley in or out on the shaft to align the
edges of the two pulleys.
4. When aligned, re-tighten the set screw on the side of the
motor pulley.
