Pretesting with scrap material is extremely important!
Place the bottom side (the side that will be against the
wall) against the Miter SAW FENCE. Place the top (that
part that will be against the ceiling) against the saw
table and the crown molding fence.
Instructions for cutting crown MOLDING angled
between the fence and the TABLE of the saw for all
cuts:
1. Angle the molding so the bottom of the molding (part
which goes against the wall when installed) is against
the fence and the top of the molding is resting on the
table of the saw.
2. The angled "flats" on the back of the molding must
rest squarely on the fence and table of the saw.

SPECIAL CUTS

NEVER MAKE ANY CUTS UNLESS THE MATERIAL IS
SECURED ON THE TABLE AND AGAINST THE FENCE.
Aluminum Cutting (Carbide tipped blade only)
Aluminum extrusions such as those used when making
aluminum screens and storm windows can easily be cut
with your saw using the proper blade designed for non-fer-
rous metal cutting. Position the material so that you will be
cutting the thinnest cross section, as shown in Figure 9.
Figure 10 illustrates the wrong way to cut these extrusions.
Use a wax lubricant when cutting aluminum 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.
Be sure to properly secure work. Certain workpieces, due
to their size, shape or surface finish, may require the use of
a clamp, jig or fixture to prevent movement during the cut.
Bowed Material
When cutting bowed material always position it as shown
in Figure 11 and never like that shown in Figure 12.
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 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 making angle cuts.

MAINTENANCE

(PERFORM ALL MAINTENANCE WITH MITER SAW
UNPLUGGED.)
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 in this manual or return the tool to the
nearest service center for repair.
Important
To assure product SAFETY and RELIABILITY, repairs,
maintenance and adjustment (including brush inspection
and replacement) should be performed by authorized
service centers or other qualified service organizations,
always using identical replacement parts.
