•
Double insulation eliminates the need for the three-wire grounded power
cord and grounded power-supply
system. Applicable only to Class II (doubleinsulated) tools. This compound miter saw is a double insulated tool.
_,
WARNING:
precautions
Double insulation does not take the place of normal safety
when operating this tool.
•
Before plugging in the tool, be sure that the outlet voltage supplied is within
the voltage marked on the tool's data plate. Do not use "AC only" rated tools
with a DC power supply.
•
Avoid body contact with grounded surfaces, such as pipes, radiators,
ranges, and refrigerators. There is an increased risk of electric shock if your
body is grounded while using the tool.
•
Do not expose power tools to rain or wet conditions or use power tools in
wet or damp locations. Water entering a power tool will increase the risk of
electric shock. This tool is intended for indoor use only.
•
If operating a power tool in damp locations is unavoidable, always use a
ground-fault circuit interrupter to supply power to your tool. Always wear
electrician's rubber gloves and footwear in damp conditions.
•
Inspect tool cords for damage. Have damaged tool cords repaired at a Sears
Service Center. Be sure to stay constantly aware of the cord's location and
keep the cord well away from the moving blade.
•
Do not abuse the cord. Never use the cord to carry the tool by or to pull
the plug from the outlet. Keep the cord away from heat, oil, sharp edges,
and moving parts. Replace damaged cords immediately. Damaged cords
increase the risk of electric shock.
EXTENSION CORDS
Use a proper extension cord. Make sure that extension cords are in good
condition. When using an extension cord, be sure to use a cord heavy
enough to carry the drawn current needed by the compound miter saw. An
undersized cord will cause a drop in line voltage, resulting in loss of power
and overheating. The table on the following page shows the correct size
to use, depending on the cord length and nameplate ampere rating. If in
doubt, use the next heavier gauge: the smaller the gauge number, the heavier
the cord.
•
Be sure extension cords are properly wired and in good condition. Always
replace a damaged extension cord or have it repaired by a qualified person
before using it. Protect extension cords from sharp objects, excessive heat,
and damp or wet areas.
•
Use a separate electrical
circuit for power tools. This circuit must not
be less than #6 wire and should be protected with a time-delay fuse. Before
connecting the tool to the power line, make sure the switch is in the "OFF"
position and the electric current is rated the same as the current stamped on
the motor nameplate; running at a lower voltage will damage the motor.

KNOW THE COMPOUND
MITER
SAW (Fig. 1)
NOTE: Before attempting to use your saw, familiarize yourself with all of the
features, operating instructions, and safety requirements.
Your miter saw has a precision-built
electric motor which should be connected
only to a 120-volt, 60-Hz AC ONLY power supply (normal household current).
Do not operate on direct current (DC): the large voltage drop will cause a loss of
power and the motor will overheat. If the saw does not operate when plugged
into a correct 120-volt, 60-Hz AC ONLY outlet, check the power supply. The saw
comes with an 8-ft. power cord (no adapter needed).

CUTTING
BASE MOLDING
(Fig. 36)
Base moldings and many other moldings
can be cut on a miter saw. The proper
setup of the saw depends on base molding
characteristics and applications, as
described below. Perform practice cuts on
scrap materials to achieve best results.

2.
Always make sure moldings rest firmly
against the fence and table. Use holddown clamp provided, a crown molding
vise, or C-clamps and place tape on the
area being clamped to avoid marks on
the workpiece.
Reduce splintering by taping the cut
area prior to making the cut. Mark the cut
line directly on the tape.

A compound miter cut is a cut made using a miter angle and a bevel angle at the
same time. This type of cut is used for decorative moldings, picture frames, and
other fine joinery.
To make this type of cut, the miter table must be rotated to the correct
angle and the saw arm must be tilted to the correct bevel angle.
Always take special care when making compound

Adjustments of miter and bevel settings are dependent on one another. Each time the
miter setting is adjusted, the effect of the bevel setting also changes. Each time the
bevel setting is adjusted, the effect of the miter setting is changed.
It may take several settings to obtain the desired cut. The first angle setting
should be checked after setting the second angle, since adjusting the second
angle affects the first.

0.005 °
(Fig. 38)
Your miter saw is ideal for cutting crown molding. In order to fit properly, crown
molding must be compound-mitered
with extreme accuracy. To fit flat against the
ceiling and wall, the sum of the angles of the crown molding's two connecting
surfaces must equal 90 °
Most crown molding has a high top rear spring angle (the section that fits flat
against the ceiling) of 52 ° and a bottom rear spring angle (the section that fits flat
against the wall) of 38 °
In order to accurately cut crown molding for a 90 ° inside or outside corner,
lay the molding with its broad back surface flat on the miter table and against
the fence. When setting the bevel and miter angles for compound miter cuts,
remember that the settings are interdependent;
changing one changes the other.
Keep in mind that, since it is very easy for the angles of crown molding to shift
slightly, all settings should be tested on scrap molding. Also, most walls do not
have angles of precisely 90 ° , therefore, you will need to fine tune your settings.
When cutting crown molding using this method, the bevel angle should be set
at 33.9 o. The miter angle should be set at 31.6 ° either left or right, depending
upon the desired cut for the application. See the following table for correct angle
setting and correct positioning of the crown molding on the miter table.
The settings in the table below can be used for cutting all standard (U.S.) crown
molding with 52 °And 38 o spring angles. The crown molding is placed flat on the
miter table, using the compound features of your miter saw.
Always use the hold-down clamp, and place tape on the area being clamped
avoid marks on the workpiece.
