ELECTRICAL SAFETY
GENERAL ELECTRICAL CONNECTIONS

DANGER: To reduce the risk of electrocution:

1. Use only identical replacement parts when servicing. Servicing should be
performed by a qualified service technician.

2. Do not use in rain or where floor is wet. This tool is intended for indoor use only.

110-120-Volt, 60 Hz. Tool Information

The plug supplied on your tool may not fit into the outlet you are planning to use."Yourlocal
electrical code may require slightly different power cord plug connections. If these

differences exist refer to and make the proper adjustments per your local code before your
tool is plugged in and turned on.

In the event of a malfunction or breakdown, grounding provides a path of least resistance

for electric current to reduce the risk of electric shock. This tool is equipped with an electric
cord having an equipment-grounding conductor and a grounding plug, as shown in

Figure A. The plug must be plugged into a matching outlet that is properly installed and

grounded in accordance with all local codes and ordinances.

Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed
by a qualified electrician.

A temporary adapter may be used to connect this plug to a 2-prong outlet (as shown in

Figure A), if a properly grounded 3-prong outlet is not available. This temporary adapter
should be used only until a properly grounded 3-prong outlet can be installed by a qualified
electrician. The green colored rigid ear, lug or the like, extending from the adapter must be

connected to a permanent ground, such as a properly grounded outlet box.

Improper connection of the equipment-grounding conductor can result in a risk of electric
shock. The conductor with insulation having an outer surface that is green with or without
yellow stripes is the equipment-grounding conductor. If repair or replacement of the electric

cord or plug is necessary, do not connect the equipment-grounding conductor to a live

terminal.

WARNING: : Do not permit fingers to touch the terminals of plug when

installing or removing the plug to or from the outlet.

If the grounding instructions are not completely understood, or if you are in doubt as to

whether the tool is properly grounded, check with a qualified electrician or service

personnel.

WARNING: :If not properly grounded, this tool can cause an electrical

shock, particularly when used in damp locations, in proximity to plumbing, or out
of doors. If an electrical shock occurs there is the potential of a secondary

hazard, such as your hands contacting the saw blade.

GENERAL ELECTRICAL CONNECTIONS cont.

NOTE: The adapter illustrated is for use
only if you already have a properly
grounded 2-prong outlet.

NOTE: In Canada, the use of a temporary
adapter is not permitted by the Canadian

1. If operating the 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.

2. DO NOT expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.

3. ALWAYS periodically inspect tool cords and extension cords for damage. Have
damaged cords repaired at a Sears Service Center. BE SURE to stay constantly aware
of the cord location and keep itwell away from the moving blade.

4. ALWAYS use the proper extension cord and MAKE SURE the cord is in good
condition. ONLY USE a cord that is heavy enough to carry the current your tool
will draw. An undersized cord will cause a current drop in line voltage resulting in a loss
of power and overheating. A wire gauge size AWG (American Wire Gauge) of at least

14 is recommended for an extension cord 25 feet or less in length. If in doubt, use the
next heavier size. Smaller gauge wires, have greater capacity (14 gauge wire has more

capacity than 16 gauge wire).

5. DO NOT abuse the cord. NEVER use the cord to pull the plug from the outlet. Keep
cord away from heat, oil, sharp edges or moving parts. Replace damaged cords

immediately. Damaged cords increase the risk of electric shock.

6. When operating a power tool outside, ALWAYS use an outdoor extension cord marked
"W-A" or "W". These cords are rated for outdoor use and reduce the risk of electric

shock.

/_ WARNING: DO NOT attemptto modify this tool or create accessories not recommended for

this tool. Any such alteration or modification is misuse and could result in a hazardous condition

leading to possible serious personal injury.

/ WARNING: DO NOT connect to power supply untilassembly is complete. Failure to comply

could result in accidental starting and possible serious personal injury.

/ WARNING: ALWAYS make sure your compound miter saw is securely mounted to a

workbench or an approved work stand. Failureto do so could result in an accident, resulting

in possibleserious personal injury.

Mounting Holes (See Fig. 10)

Your compound miter saw should be permanently mounted to a firm, stable supporting surface,
such as a workbench. Four bolt holes have been provided in the saw base for this purpose.

Each of these four mounting holes should be securely bolted using 3/8-in. machine bolts, lock

washers and hex nuts (not included). Bolts should be long enough to fit through the saw base,

lockwashers, hex nuts and the thickness of the workbench.

Tighten all four bolts securely.
The hole pattern for an 18 x 24-in. workbench isshown in Figure 10. Carefully check the workbench

after mounting the saw 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 Fig. 11)
The work clamp provides greater control by clamping the workpiece to the fence or the saw table.

It also prevents the workpiece from creeping towards the saw blade. This isvery 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 (not included) instead of the work clamp to secure the workpiece prior to making the cut.

\ 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

priorto beginning any cutting operation to reduce the risk of serious personal injury.

Follow these instructions to install the work clamp:

1. Place the shaft of the work clamp in either hole on the saw table base.

2. Rotate the knob on the work clamp to move it in or out as needed.

WARNING: When usingany clamp with a stop block, installthe clamp on the same side as

the stop block.This will eliminate the possibilityof trapping the workpiece, resulting in the saw

blade and workpiece kickingup. Failure to heed thiswarning can result in serious personal injury.

Your compound miter saw has been adjusted at the factory for making very accurate cuts.

However, some of the components may have been jarred out of alignment during shipping.
Also over a period of time, some readjustment will probably become necessary due to wear.
After unpacking your saw, check the following adjustments BEFORE using your saw.
Make any adjustments that are necessary and periodically check the parts alignment to be sure
that your saw is cutting accurately.

NOTE: Many of the drawings in this manual show only portions of your compound miter saw.
This was intentional, so we can clearly illustrate the points being made. NEVER operate your saw
without all the guards securely in place and in good operating condition.

PIVOT ADJUSTMENTS
NOTE: These adjustments were made at the factory and under normal circumstances do not

require readjustment.

Travel Pivot Adjustment
Your saw arm should rise completely to the up position by itself.

To avoid risk of personal injury, if your saw arm does not rise by itself or if there is play

in the pivot joints, have your saw serviced at a Sears Service Center before using.
Bevel Pivot Adjustment

Your compound miter saw arm should bevel easily by loosening the bevel lock knob and tilting
the saw arm to the left.

To avoid risk of personal injury, if movement is tight or if there is play in the pivot, have
your saw serviced at a Sears Service Center before using

DEPTH STOP (see Figure 24)

The depth stop limitsthe downward travel of the blade. It allows the blade to go below the miter
table enough to maintain full cutting capacities. The depth stop positions the blade 1/4-inch from
the miter table support.

NOTE: The miter table support is located inside the miter table.

The depth stop is factory set to provide maximum cutting capacity for the 10-inch blade included
with your saw.Therefore the blade included with your saw should never need adjustments.

However, when the diameter of the blade has been reduced due to sharpening, it may become
necessary to adjust the depth stop in order to provide the maximum cutting capacity.

Also, when a new blade is installed, itis necessary to check the clearance of the blade to the miter
table support before starting the saw. Make adjustments if necessary.

COMPOUND MITER CUTTING
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 moldings, picture frames, and boxes with sloping sides.
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.
ALWAYS take special care when making compound miter setups due to the interaction of the

two angle settings.
Adjustments of miter and bevel settings are dependent on 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.

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.
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.

CUTTING CROWN MOLDING
Your compound miter saw is excellent for cutting crown molding.

In order for it 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 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 °.

Laying Molding Flat on the Miter Table (See Figure 31)

To use this method foraccurately 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.
Remember that when you set the bevel and miter angles for compound miters, the settings are

interdependent. When you change one angle, the other angle ischanged as well.
Keep in mind that the angles for crown molding are very precise and difficult to set. Since it isvery

easy for these angles to shift, all settings should first 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 33.85 ° .The miter
angle should be set at 31.62 ° either left or right, depending upon the desired cut for the application.

See the following Cutting Crown Molding 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° angles. The crown molding is placed flat on the miter table, using the compound features
of your miter saw.

CUTTING WARPED MATERIAL (See Figures 32 - 33)

When cutting warped material, ALWAYS make sure that it is positioned on the
miter table with the convex side against the fence, as shown in Figure 32.

If the warped material is positioned the wrong way, as shown in Figure 33,

it will pinch the blade near the end of the cut.

/ WARNING: To avoid kickback and to avoid serious personal injury NEVER

position the concave side of bowed or warped material against the fence.

39

CLAMPING WIDE WORKPIECES
When cutting wide workpieces (such as 2-in x 6-in. boards), the boards should ALWAYS be

clamped with a hold-down clamp or a C-clamp.

/_WARNING: When servicing, use only identical replacement parts. Use of any other part

may create a hazard or cause product damage.

Z_WARNING: ALWAYS wear safety goggles or safety glasses with side shields during power

tool operation, or when blowing dust. If operation is dusty, also wear a dust mask.

GENERAL

• Avoid solvents when cleaning plastic parts. Most plastics are susceptible to damage from various
types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt,

carbon dust, etc.

i_WARNING: DO NOT at any time let brake fluids, gasoline, petroleum-based products,

penetrating oils, etc. come in contact with plastic parts. Chemicals can damage, weaken or destroy
plastic which may result in serious personal injury.

It has been found that electric tools are subject to accelerated wear and possible premature failure
when they are used to work on fiber glass boats and sports cars, wallboard, spackling compounds
or plaster. The chips and grindings from these materials are highly abrasive to electrical tool parts,
such as bearings, brushes, commutators, etc. Consequently, it is not recommended that this tool
be used for extended work on any fiber glass material, wallboard, spackling compound, or plaster.

During any use on these materials, itis extremely important that the tool is cleaned frequently
by blowing with an air jet.

LUBRICATION
All of the bearings in this tool are lubricated with a sufficient amount of high-grade lubricant for the

life of the tool under normal operating conditions.Therefore, no further lubrication is required.

i_WARNING: To ensure safety and reliability, all repairs with the exception of the externally

accessible brushes should be performed by a qualified service technician at a Sears store to avoid
the risk of personal injury.

40

BRUSH REPLACEMENT (See Figure 34-35)
Your saw has externally accessible brushes that should be periodically checked for wear.

When replacement is necessary, follow these steps:

1. Unplug the saw.

/ WARNING: To prevent personal injury, ALWAYS disconnect the plug from power source

BEFORE assembling parts, making adjustments or changing blades.

2. Remove brush cap with a screwdriver. Brush assembly is spring loaded and will pop out

when you remove brush cap.

3. Remove brush assembly.

4. Check for wear. Replace both brushes when either has less than 1/4-inch length of carbon

remaining. DO NOT replace one side without replacing the other.

5. Reassemble using new brush assemblies. Make sure the curvature of brush matches curvature

of motor and the brush moves freely in brush tube.

6. Make sure the brush cap is oriented correctly (straight) and replace.

7. Retighten brush cap securely. DO NOT overtighten.

Sears offers a large selection of blades, table extensions, roller tables, extension cords and more

that are ideal for use with your 10-inch compound miter saw for a variety of cutting needs.

/ .kWARNING: The use of attachments or accessories not sold by Sears may result

in serious personal injury.

EXTENSION CORDS

The use of any extension cord will cause some loss of power. To keep the loss at a minimum
and to prevent overheating, use an extension cord that is heavy enough to carry the current

that the tool will draw.
A wire gauge (AWG) of at least 14 is recommended for an extension cord 25 feet or less in

length. When working outdoors ALWAYS use an extension cord that is suitable for outdoor use.

The cord's jacket will be marked WA.

/t kCAUTION: Keep extension cords away from the cutting area and position the cord so it

will not get caught on lumber, tools, etc. during the cutting operation.

, WARNING: Check extension cord before each use. If damaged, replace it immediately.

NEVER use a tool with a damaged cord because touching the damaged area could cause

electrical shock, resulting in serious injury.
