ELECTRICAL  
DOUBLE INSULATION  
EXTENSION CORDS  
Double insulation is a concept in safety in electric power  
tools, which eliminates the need for the usual three-  
wire grounded power cord. All exposed metal parts are  
isolated from the internal metal motor components with  
protecting insulation. Double insulated tools do not need  
to be grounded.  
When using a power tool at a considerable distance from  
a power source, be sure to use an extension cord that has  
the capacity to handle the current the tool will draw. An  
undersized cord will cause a drop in line voltage, resulting in  
overheating and loss of power. Use the chart to determine  
the minimum wire size required in an extension cord. Only  
round jacketed cords listed by Underwriter’s Laboratories  
(UL) should be used.  
WARNING:  
When working outdoors with a tool, use an extension  
cord that is designed for outside use. This type of cord is  
designated with “WA” on the cord’s jacket.  
The double insulated system is intended to protect  
the user from shock resulting from a break in the tool’s  
internal insulation. Observe all normal safety precautions  
to avoid electrical shock.  
Before using any extension cord, inspect it for loose or  
exposed wires and cut or worn insulation.  
NOTE: Servicing of a tool with double insulation requires  
extreme care and knowledge of the system and should be  
performedonlybyaqualifiedservicetechnician. Forservice,  
we suggest you return the tool to the nearest authorized  
service center for repair. Always use original factory replace-  
ment parts when servicing.

**Used on 12 gauge - 20 amp circuit.  
NOTE: AWG = American Wire Gauge  
This tool has a precision-built electric motor. It should be  
connected to a power supply that is 120 volts, 60 Hz, AC  
only (normal household current). Do not operate this tool  
on direct current (DC). A substantial voltage drop will cause  
a loss of power and the motor will overheat. If the tool does  
not operate when plugged into an outlet, double-check the  
power supply.  
WARNING:  
Keep the extension cord clear of the working area.  
Position the cord so that it will not get caught on lumber,  
tools or other obstructions while you are working with a  
power tool. Failure to do so can result in serious personal  
injury.  
WARNING:  
Check extension cords before each use. If damaged  
replace immediately. Never use tool with a damaged cord  
since touching the damaged area could cause electrical  
shock resulting in serious injury.

WARNING:  
Always make sure the compound miter saw is securely  
mounted to a workbench or an approved workstand.  
Failure to heed this warning can result in serious  
personal injury.  
The compound miter saw should be mounted to a firm  
supporting surface such as a workbench. Four bolt holes  
have been provided in the saw base for this purpose. Each  
of the four mounting holes should be bolted securely using  
3/8 in. machine bolts, lock washers, and hex nuts (not  
included). Bolts should be of sufficient length to accommodate  
the saw base, lock washers, hex nuts, and the thickness of the  
workbench. Tighten all four bolts securely.  
WARNING:  
If any parts are damaged or missing do not operate this tool  
until the parts are replaced. Failure to heed this warning  
could result in serious personal injury.  
WARNING:  
The hole pattern for mounting to a workbench is shown in fig-  
ure 7. Carefully check the workbench after mounting to make  
sure that no movement can occur during use. If any tipping,  
sliding, or walking is noted, secure the workbench to the floor  
before operating.

WORK CLAMP  
See Figure 10.  
The work clamp provides greater control by clamping the  
workpiece to the fence. It also prevents the workpiece from  
creeping toward the saw blade. This is very helpful when  
cutting compound miters.  
Depending on the cutting operation and the size of the  
workpiece, it may be necessary to use a C-clamp instead  
of the work clamp to secure the workpiece to the miter table  
prior to making the cut.

PORT  
WARNING:  
In some operations, the work clamp assembly may  
interfere with the operation of the blade guard assembly.  
Always make sure there is no interference with the blade  
guard prior to beginning any cutting operation to reduce  
the risk of serious personal injury.  
Fig. 9  
To install the work clamp:  
Place the shaft of the work clamp in either hole on the  
miter table base.  
Rotate the knob on the work clamp clockwise to move  
it in or counterclockwise to move it out as needed.

ALIGNING THE LASER GUIDE LINE  
See Figure 12.  
Unplug the saw. Draw a line on the workpiece. When the  
laser guide switch is turned on it will generate a red line on  
the work surface. This line will let you see your mark and the  
laser guide line at the same time, and will assist you in lining  
up the mark for more accurate cutting of the workpiece.  
Align the laser line and the mark with the blade at the up-  
permost position. Once both lines are in alignment, do not  
move the workpiece.

OPERATION  
CUTTING WITH YOUR COMPOUND  
MITER SAW  
WARNING:  
Do not allow familiarity with tools to make you care-  
less. Remember that a careless fraction of a second is  
sufficient to inflict serious injury.  
WARNING:  
When using a work clamp or C-clamp to secure the  
workpiece, clamp workpiece on one side of the blade  
only. The workpiece must remain free on one side of the  
blade to prevent the blade from binding in workpiece. The  
workpiece binding the blade will cause motor stalling and  
kickback. This situation could cause an accident resulting  
in possible serious personal injury.  
WARNING:  
Always wear eye protection with side shields marked to  
comply with ANSI Z87.1. Failure to do so could result in  
objects being thrown into your eyes, resulting in possible  
serious injury.  
WARNING:  
WARNING:  
NEVER move the workpiece or make adjustment to any  
cutting angle while the saw is running and the blade is  
rotating. Any slip can result in contact with the blade  
causing serious personal injury.  
Do not use any attachments or accessories not  
recommended by the manufacturer of this tool. The use  
of attachments or accessories not recommended can  
result in serious personal injury.  
TO CROSS CUT  
See Figure 23.  
APPLICATIONS  
You may use this tool for the following purposes:  
A cross cut is made by cutting across the grain of the  
workpiece. A straight cross cut is made with the miter  
table set at the 0° position. Miter cross cuts are made  
with the miter table set at some angle other than zero.  
Cross cutting wood and plastic

CROSS CUT  
WARNING:  
Before starting any cutting operation, clamp or bolt the  
compound miter saw to a workbench. Never operate the  
miter saw on the floor or in a crouched position. Failure  
to heed this warning can result in serious personal injury.  
WARNING:  
To avoid serious personal injury, always tighten the miter  
lock handle and bevel lock knob securely before making  
a cut. Failure to do so could result in movement of the  
control arm or miter table while making a cut.  
WARNING:  
To avoid serious personal injury, keep hands outside  
the no hands zone, at least 3 in. from blade. Never per-  
form any cutting operation freehand (without holding  
workpiece against the fence). The blade could grab the  
workpiece if it slips or twists.

TO COMPOUND MITER CUT  
See Figures 26 - 27.  
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 to  
make picture frames, cut molding, make boxes with sloping  
sides, and for certain roof framing cuts.  
WORK  
To make this type of cut the control arm on the miter table  
must be rotated to the correct angle and the saw arm must  
be tilted to the correct bevel angle. Care should always  
be taken when making compound miter setups due to the  
interaction of the two angle settings.  
CLAMP  
Fig. 26  
Before turning on the saw, perform a dry run of the cutting  
operation just to make sure that no problems will occur  
when the cut is made. Make a test cut in scrap material.  
Adjustments of miter and bevel settings are interdependent  
with one another. Each time you adjust the miter setting you  
change the effect of the bevel setting. Also, each time you  
adjust the bevel setting you change the effect of the miter  
setting.  
Place the workpiece flat on the miter table with one edge  
securely against the fence. If the board is warped, place  
the convex side against the fence. If the concave edge  
of a board could collapse on the blade at the end of the  
cut, jamming the blade.  
It may take several settings to obtain the desired cut. The

When cutting long pieces of lumber or molding, support  
the opposite end of the stock with a roller stand or with  
a work surface level with the miter table. See Figure 28.  
Once the two correct settings for a particular cut have been  
obtained, always make a test cut in scrap material before  
making a finish cut in good material.

OPERATION  
Whensettingthebevelandmiteranglesforcompoundmiters,  
remember that the settings are interdependent; changing  
one angle changes the other angle as well.  
CUTTING CROWN MOLDING  
The compound miter saw does an excellent job of cutting  
crown molding. In general, compound miter saws do a bet-  
ter job of cutting crown molding than any other tool made.  
Keep in mind that the angles for crown moldings are very  
precise and difficult to set. Since it is very easy for these  
angles to shift, all settings should first be tested on scrap  
molding. Also most walls do not have angles of exactly 90°,  
therefore, you will need to fine tune your settings.  
In order to fit properly, crown molding must be compound  
mitered with extreme accuracy.  
The two contact surfaces on a piece of crown molding that  
fit flat against the ceiling and the wall of a room are at angles  
that, when added together, equal exactly 90°. Most crown  
molding has a top rear angle (the section that fits flat against  
the ceiling) of 52° and a bottom rear angle (the section that  
fits flat against the wall) of 38°.  
When cutting crown molding by this method the bevel angle  
should be set at 33.9°. The miter angle should be set at 31.6°  
either right or left, depending on the desired cut for the ap-  
plication. See the chart below for correct angle settings and  
correct positioning of crown molding on miter table.  
LAYING MOLDING FLAT ON THE MITER  
TABLE  
See Figure 29.  
The settings in the chart on page 24 can be used for cutting  
All Standard (U.S.) crown molding with 52° and 38° angles.  
The crown molding is placed flat on the miter table using  
the compound features of your miter saw.  
To use this method for accurately cutting 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.

WARNING:  
To avoid a kickback and to avoid serious personal injury,  
never position the concave edge of bowed or warped  
material against the fence.  
CUTTING WARPED MATERIAL  
See Figures 30 - 31.  
When cutting warped material, always make sure it is posi-  
tioned on the miter table with the convex side against the  
fence as shown in figure 30.  
CLAMPING WIDE WORKPIECES  
See Figure 32.  
If the warped material is positioned the wrong way as shown  
in figure 31, it will pinch the blade near the completion of  
the cut.  
When cutting wide workpieces, such as 2 in. x 6 in., boards  
should be clamped with a C-clamp as shown in figure 32.

ADJUSTMENTS  
POSITIVE STOP ADJUSTMENTS  
See Figure 33.  
WARNING:  
Before performing any adjustment, make sure the tool is  
unplugged from the power supply. Failure to heed this  
warning could result in serious personal injury.  
These adjustments were made at the factory and normally  
do not require readjustment.  
To adjust:  
Unplug the saw.  
The compound miter saw has been adjusted at the  
factory for making very accurate cuts. However, some of  
the components might have been jarred out of alignment  
during shipping. Also, over a period of time, readjustment  
willprobablybecomenecessaryduetowear.Afterunpacking  
the saw, check the following adjustments before you begin  
using saw. Make any readjustments that are necessary and  
periodically check the parts alignment to make sure that the  
saw is cutting accurately.  
Loosen the bevel lock knob by turning the knob coun-  
terclockwise.  
Square the blade to the miter table as described in the  
Assembly section of this manual.  
If the blade is out of square, adjust by tightening or loos-  
ening the positive stop adjustment screw to bring blade  
into alignment.  
Retightenbevellockknob. Recheckblade-to-tablealign-  
ment.  
NOTE: The above procedure can be used to check blade  
squareness of the saw blade to the miter table at both 0°  
and 45° angles.  
CAUTION:  
Do not start the compound miter saw without checking  
for interference between the blade and the throat plate.  
Damage could result to the blade if it strikes the throat  
plate during operation of the saw.  
The saw has two scale indicators, one on the bevel scale  
and one on the miter scale. After squaring adjustments have  
been made, it may be necessary to loosen the indicator  
screws and reset them to zero.  
PIVOT ADJUSTMENTS  
NOTE: These adjustments were made at the factory and  
normally do not require readjustment.
