feel the lock engage. Continue to hold the lock button in to
keep the spindle from turning.
3) Using the blade wrench, remove the blade screw and
carefully remove the blade.
The inner clamp washer is installed first, then the blade
adapter. The blade adapter is designed to permit the use of
saw blades with 1" (25.4mm) arbor holes as well as those
with 5/8" (15.8mm) arbor holes.
When using blades with 1" (25.4mm) arbor holes, install the
blade adapter over the spindle shaft and against the inner
clamp washer. Next, install the saw blade making sure
that the arbor hole in the blade fits on the blade adapter.
Make sure that the teeth at the bottom of the blade are
pointing toward the back of the saw (away from the
operator). Install the outer clamp washer and install the
blade screw. Tighten firmly using the spindle lock and the
provided wrench (left hand threads). When using saw
blades with 5/8" (15.8mm) arbor holes, remove the blade
adapter! Save it in a safe place for future use. The rest of
the blade assembly is exactly the same.

Removing and Replacing Belt

The belt is designed to last the life of the tool. However,
abuse of the tool could cause the belt to fail.
If the blade does not turn when the motor is running, the
belt has failed. To inspect or replace the belt, remove the
belt cover screw. Remove the belt cover. Inspect the ribs of
the belt for wear or failure. Check belt tension by squeezing
the belt as shown in Figure 38. The belt should contact the
center boss with medium pressure.
To adjust the tension, loosen, but do not remove, the six
Phillips head screws (Figure 38). Then rotate the set
screw on the top of the motor plate casting until the proper
tension is achieved. Tighten the six screws securely and
replace the belt cover. NOTE: Overtightening the belt will
cause premature motor failure.

Maintenance

1. All bearings are sealed ball bearings. They are
lubricated for life and need no further maintenance. Do
not use WD-40 or any other lubricant.
2. Periodically clean all dust and wood chips from around
the area of the saw. Even though slots are provided to
allow debris to pass through, some dust will accumulate.
3. The brushes are designed to give you several years of
use. If they ever need replacement follow the
instructions on page 9 or return the tool to the nearest
service center for repair. Service center locations are
