Special Cuts

FIG. 33
NEVER MAKE ANY CUT UNLESS THE MATERIAL IS
SECURED ON THE TABLE AND AGAINST THE FENCE.
Aluminum Cutting:
Certain workpieces, due to their size, shape or surface
finish, may require the use of a clamp or fixture to prevent
movement during the cut. Position the material so that you
will be cutting the thinnest cross section, as shown in Figure
32. Figure 33 illustrates the wrong way to cut these
extrusions. Use a wax lubricant when cutting aluminum
BLADE
such as Johnson's Stick Wax No. 140. Apply the stick wax
directly to the saw blade before cutting. Never apply stick
wax to a moving blade.
The wax, available at most hardware stores and industrial
mill supply houses, provides proper lubrication and keeps
chips from adhering to the blade.
WRONG
Be sure to properly secure workpiece. Refer to page 5 for
correct saw blade,
Bowed Material:
When cutting bowed material always position it
as shown in Figure 34 and never like that shown in Figure
35. Positioning the material incorrectly will cause it to pinch
the blade near the completion of the cut.
Cutting Plastic Pipe and Other Round Cross-Sectional
Material
Plastic pipe and similar material can be easily cut with your
saw. It should be cut just like wood and CLAMPED OR HELD
FIRMLY TO THE FENCE TO KEEP IT FROM ROLLING
PARTICULARLY WHEN CUTTING ANGLES.
Cutting Large Material
Occasionally you will encounter a piece of wood a little too
large to fit beneath the blade guard. A little extra height can be
gained by rolling the guard up out of the way, as shown in
Figure 28. Avoid doing this as much as possible, but if need
be, the saw will operate properly and make the bigger cut.
NEVER TIE, TAPE, OR OTHERWISE HOLD THE GUARD
OPEN WHEN OPERATING THIS SAW.
GROOVING
Your sliding compound miter saw is equipped with a grooving
lever and thumbscrew and wingnut to allow for groove cutting.
To use the grooving feature, flip the grooving lever toward the
front of the saw, as shown in Figure 36.
Loosen the wingnut and adjust the thumbscrew to change the
depth of the groove cut. To lock the thumbscrew in
position,retighten the wingnut. ALWAYS MAKE DRY RUNS
(UNPOWERED) BEFORE FINISH CUTS SO THAT YOU
CAN CHECK THE DEPTH OF THE BLADE.
NOTE: Your saw is not designed for use with dado blades.

Installing a New Saw Blade

UNPLUG THE SLIDING COMPOUND MITER SAW
DO NOT CUT FERROUS METAL (THAT WITH AN IRON
OR STEEL CONTENT) OR MASONRY WITH THIS
SLIDING COMPOUND MITER SAW.
Before installing or removing a blade, always lock the miter
adjustment/lock handle, lock the rail lock knob, and lock the
bevel adjustment/lock handle.
1) Loosen the arbor cover screw, and pivot the arbor cover
2) While holding the spindle lock, use the supplied blade
NOTE: To use the spindle lock (Figure 38), depress the
button as shown and rotate the blade by hand until you 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
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
counterclockwise 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.
REPLACE AND SECURE ARBOR COVER TO PREVENT
BLADE SCREW AND BLADE SEPARATION FROM
SPINDLE SHAFT.
NEVER DEPRESS THE SPINDLE LOCK PIN WHILE
THE BLADE IS ROTATING.

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 39. The belt should contact the center
boss with medium pressure.

up, as shown in Figure 37. NOTE: This screw is a specific
length to provide a caliper for the blade to prevent guard
damage. Do not replace this screw with a different screw.

carefully remove the blade.
