WARNING: Do not cut material using the special setup
without properly installing the backfence screws, otherwise
the material will not be supported properly and may cause
loss of control and possible injury.
3. Make a platform using a piece of 1.5 inch (38 mm)
thick particleboard or similar flat strong 1.5 inch thick
wood to the dimensions: 14.5" x 26" (368 x 660 mm).
The platform must be flat otherwise the material could
move during cutting and cause injury.
4. Mount the 14.5" x 26" platform to the saw using
4 three-inch long wood screws through the holes in
the base fence (Fig. 24). Four screws must be used to
properly secure the material. When the special set up
is used, the platform will be cut into two pieces. Ensure
the screws are tightened properly otherwise material
could loosen and cause injury. Ensure the platform is
firmly flat on the table, against the fence, and centered
evenly from left to right.
_&WARNING: Ensure the saw is mounted firmly to a
stable flat surface. Failure to do so could cause the saw
to be unstable and fall causing personal injury.
5. Place the workpiece to be cut on top of the platform
mounted to the table. Ensure the workpiece is firmly
against the backfence screws (Fig. 25).
6. Secure the material before cutting. Cut slowly through
the material using a out-down-and-back motion.
Failure to clamp securely or cut slowly could result in
the material coming loose and causing injury.
After several cuts are made at various miter angles other
than 0°, the platform may weaken and not properly support

the work. Install a new, unused platform to the saw after
presetting the desired miter angle.
_&CAUTION: Continued use of a platform with several
kerfs may cause loss of material control and possible
injury.
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 screws. 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 26. The belt halves should almost
touch when squeezing firmly with the thumb and index
finger. To adjust the tension, loosen, but do not remove,
the four Phillips head screws shown. Then rotate the set
screw on the top of the motor plate casting until the proper
tension is achieved. Tighten the four screws securely and
replace the belt cover.
NOTE: Over tightening the belt will cause premature motor
failure.
Maintenance
DO NOT use lubricants or cleaners (particularly spray
or aerosol) in the vicinity of the plastic guard. The
polycarbonate material used in the guard is subject to
attack by certain chemicals.
1. All bearings are sealed. They are lubricated for life and
need no further maintenance.
2. Periodically clean all dust and wood chips from around
AND UNDER the base and the rotary table. 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
packed with your tool.
