POWER TOOL SAFETY

GENERAL SAFETY INSTRUCTIONS

BEFORE USING THIS POWER TOOL

Safety is a combination of common sense, staying alert

and knowing how to use your power tool.

To avoid mistakes that could cause serious injury, do not

plug the tool in until you have read and understood the

following.

1. READ

and become familiar with the entire Operators

Manual. LEARN the tool’s application, limitations and

possible hazards.

2. KEEP GUARDS IN PLACE and in working order.

3. REMOVE ADJUSTING KEYS AND WRENCHES.

Form the habit of checking to see that keys and

adjusting wrenches are removed from the tool before

turning ON.

4. KEEP WORK AREA CLEAN. Cluttered areas and

benches invite accidents.

5. DON’T USE IN DANGEROUS ENVIRONMENTS.

Don’t use power tools in damp locations, or expose

them to rain or snow. Keep work area well lighted.

6. KEEP CHILDREN AWAY.

All visitors and bystanders

should be kept a safe distance from work area.

7. MAKE WORKSHOP CHILD PROOF with padlocks,

master switches, or by removing starter keys.

8. DON’T FORCE THE TOOL. It will do the job better

and safer at the rate for which it was designed.

9. USE THE RIGHT TOOL. Do not force the tool or an

attachment to do a job for which it was not designed.

10. USE PROPER EXTENSION CORDS. Make sure

your extension cord is in good condition. When using

an extension cord, be sure to use one heavy enough

to carry the current your product will draw. An

undersized cord will result in a drop in line voltage

and in loss of power which will cause the tool to

overheat. The table on page 5 shows the correct size

to use depending on cord length and nameplate

ampere rating. If in doubt, use the next heavier gauge.

The smaller the gauge number, the heavier the cord.

11. WEAR PROPER APPAREL. Do not wear loose

clothing, gloves, neckties, rings, bracelets, or other

jewelry which may get caught in moving parts.

Nonslip footwear is recommended. Wear protective

hair covering to contain long hair.

12. ALWAYS WEAR EYE PROTECTION. Any power tool

can throw foreign objects into the eyes and

could cause permanent eye damage.

ALWAYS wear Safety Goggles (not

glasses) that comply with ANSI Safety

standard Z87.1 Everyday eyeglasses

have only impact –resistance lenses.

They ARE NOT safety glasses. Safety Goggles are

available at Sears. NOTE: Glasses or goggles not in

compliance with ANSI Z87.1 could seriously injure

you when they break.

13. WEAR A FACE MASK OR DUST MASK. Sawing

operation produces dust.

14. SECURE WORK. Use clamps or a vise to hold work

when practical. It’s safer than using your hand and it

frees both hands to operate the tool.

15. DISCONNECT TOOLS FROM POWER SOURCE

before servicing, and when changing accessories

such as blades, bits and cutters.

16. REDUCE THE RISK OF UNINTENTIONAL

STARTING. Make sure switch is in the OFF position

before plugging the tool in.

17. U SE RECOMMENDED ACCE SSORIES. Consult this

Operators Manual for recommended accessories.

The use of improper accessories may cause risk of

injury to yourself or others.

18. NEVER STAND ON THE TOOL. Serious injury could

occur if the tool is tipped or if the cutting tool is

unintentionally contacted.

19. C HECK FOR DAMAGE D PARTS. Before further use

of the tool, a guard or other part that is damaged

should be carefully checked to determine that it will

operate properly and perform its intended function –

check for alignment of moving parts, binding of

moving parts, breakage of parts, mounting, and any

other conditions that may affect its operation. A guard

or other part that is damaged should be properly

repaired or replaced.

20.

NEVER LEAVE THE TOOL RUNNING UNATTENDED.

TURN THE POWER “OFF”. Don’t walk away from a

running tool until the blade comes to a complete stop

& unplug the unit.

21. D ON'T OVER REACH . Keep proper footing and

balance at all times.

22. MAINTAIN TOOLS WITH CARE. Keep tools sharp

and clean for best and safest performance. Follow

instructions for lubricating and changing accessories.

23. WARNING: Dust generated from certain materials

can be hazardous to your health. Always operate saw

in well-ventilated area and provide for proper dust

removal.

COMPOUND MITER SAW SAFETY

SPECIFIC SAFETY INSTRUCTIONS FOR

THIS COMPOUND MITER SAW

1. USE ONLY CROSS-CUTTING SAW BLADES. When

using carbide tipped blades, make sure they have a

negative hook angle.

IMPORTANT: DO NOT USE THIN KERF BLADES-

they can deflect and contact guard and can cause

possible injury to the operator.

2. DO NOT operate the miter saw until it is completely

assembled and installed according to these

instructions.

3. IF YOU ARE NOT thoroughly familiar with the

operation of miter saws, seek guidance from your

supervisor, instructor, or other qualified person.

4. ALWAYS

hold the work firmly against the fence and

table. DO NOT perform any operation free hand (use

clamp wherever possible).

5. KEEP HANDS

out of the path of the saw blade. If the

workpiece you are cutting would cause your hands to

be within 7-1/4” inches of the saw blade, the

workpiece should be clamped in place before making

the cut.

6. BE SURE the blade is sharp, runs freely, and is free

of vibration.

7. ALLOW the motor to come up to full speed before

starting a cut.

8. KEEP THE MOTOR AIR SLOTS CLEAN and free of

chips or dust.

9. ALWAYS MAKE SURE all handles are tight before

cutting, even if the table is positioned in one of the

positive stops.

10. BE SURE both the blade and the collar are clean and

the arbor bolt is tightened securely.

11. USE only blade collars specified for your saw.

12. NEVER use blades larger or smaller in diameter

than 10-inches.

13. NEVER apply lubricants to the blade when it is

running.

14. ALWAYS check the blade for cracks or damage

before operation. Replace a cracked or damaged

blade immediately.

15. NEVER use blades recommended for operation at

less than 4800 RPM.

16. ALWAYS keep the blade guards in place and use at

all times.

17. NEVER reach around the saw blade.

18. MAKE SUR E the blade is not contacting the

workpiece before the switch is turned ON.

19. IMPORTANT: After completing the cut, release the

power switch and wait for the blade to stop before

returning the saw to the raised position.

20. MAKE SUR E the blade has come to a complete stop

before removing or securing the workpiece, changing

the workpiece angle, or changing the angle of the

blade.

21. NEVER cut metals or masonry products with this tool.

This miter saw is designed for use on wood and

wood-like products.

22. NEVER cut small pieces. If the workpiece being cut

would cause your hand or fingers to be within 7-1/4”

inches of the saw blade the workpiece is too small.

23. PROVIDE adequate support to the sides of the saw

table for long work pieces.

24. NEVER use the miter saw in an area with flammable

liquids or gases.

25. NEVER use solvents to clean plastic parts. Solvents

could possibly dissolve or otherwise damage the

material.

26. SHUT OFF the power before servicing or adjusting

the tool.

27. D ISCON NECT the saw from the power source and

clean the machine when finished using.

28. MAKE SUR E the work area is clean before leaving

the machine.

29. SHOULD any part of your miter saw be missing,

damaged, or fail in any way, or any electrical

component fail to perform properly, shut off the switch

and remove the plug from the power supply outlet.

Replace missing, damaged, or failed parts before

resuming operation.

ELECTRICAL REQUIREMENTS

POWER SUPPLY AND MOTOR SPECIFICATIONS

The AC motor used in this saw is a universal,

nonreversible type. See “MOTOR” in the “PRODUCT

SPECIFICATIONS” section on page 2.

To avoid electrical hazards, fire hazards, or damage to

the tool, use proper circuit protection. Your saw is wired

at the factory for 120V operation. Connect to a 120V, 15

Amp circuit and use a 15 amp. time delay fuse or circuit

breaker. To avoid shock or fire, if power cord is worn or

cut, or damaged in any way, have it replaced

immediately.

4

ELECTRICAL REQUIREMENTS – cont’d

DOUBLE INSULATED

The power tool is double insulated to provide a double

thickness of insulation between you and tool’s electrical

system. All exposed metal parts are isolated from the

internal metal motor components with protecting

insulation.

Replacement parts – When servicing use only identical

replacement parts.

Polarized plugs – This saw has a plug that looks like

the one shown below:

To reduce the risk of electrical shock, this saw has a

polarized plug (one blade is wider than the other). This

plug will fit in a polarized outlet only one way. If the plug

does not fit fully in the outlet, reverse the plug. If it still

does not fit, contact a qualified electrician to install the

proper outlet. Do not change the plug in any way.

Double insulation does not take the place of normal

safety precautions when operating this tool.

To avoid electrocution:

1. Use only identical replacement parts when servicing a

tool with double insulation. Servicing should be

performed by a qualified technician.

2. Do not use power tools in wet or damp locations or

expose them to rain or snow.

MOTOR SAFETY PROTECTION

IMPORTANT:

To avoid motor damage, the motor should be blown out

or vacuumed frequently to keep sawdust from interfering

with the motor ventilation.

1.

CONNECT this saw to a 120V, 15 amp. circuit with a

15 amp. time delay fuse or circuit breaker. Using the

wrong size fuse can damage the motor.

2.

If the motor won’t start, release the trigger switch

immediately. UNPLUG THE SAW. Check the saw

blade to make sure it turns freely. If the blade is free,

try to start the saw again. If the motor still does not

start, refer to the “TROUBLESHOOTING GUIDE”

3.

If the tool suddenly stalls while cutting wood, release

the trigger switch, unplug the tool, and free the blade

from the wood. The saw may now be started and the

cut finished.

4.

FUSES may “blow” or circuit breakers may trip

frequently if:

a. MOTOR is overloaded – overloading can occur if

you feed too rapidly or make too many start/stops

in a short time.

b. LINE VOLTAGE is more than 10% above or below

the nameplate voltage rating. For heavy loads, the

voltage at motor terminals must equal the voltage

specified on the nameplate.

c. IMPROPER or dull saw blades are used.

5. Most motor troubles may be traced to loose or

incorrect connections, overload, low voltage or

inadequate power supply wiring. Always check the

connections, the load and supply circuit if the motor

doesn’t run well. Check minimum gauge for the length

of cord you are using on the chart below.

GUIDELINES FOR EXTENSION CORDS

Use a proper extension cord. Make sure your

extension cord is in good condition. When using an

extension cord, be sure to use one heavy enough to

carry the current your product will draw. An undersized

cord will cause a drop in line voltage, resulting in loss of

power and cause overheating. The table below shows

the correct size to use depending on 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 your extension cord is properly wired and in

good condition. Always replace a damaged extension

cord or have it repaired by a qualified person before

using it. Protect your extension cords from sharp objects,

excessive heat and damp or wet areas.

Use a separate electrical circuit for your tools. This

circuit must not be less than # 12 wire and should be

protected with a 15 Amp 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.

MOUNTING THE MITER SAW (Fig. O)

To avoid injury from unexpected saw movement:

 Before moving the saw, disconnect the power cord

from the outlet, and lock the cutting arm in the lower

position using the stop latch.

NOTE: The stop latch is for carrying or storing the tool. It is

NOT to be used holding the saw while cutting.

 Never carry the miter saw by the power cord or by the

switched handle. Carrying the tool by the power cord

could cause damage to the insulation or wire

connections resulting in electric shock or fire.

 To avoid injury from flying debris, do not allow visitors

to stand behind the saw.

 Place the saw on a firm, level work-surface where

there is room for handling and properly supporting the

workpiece.

 Support the saw on a level work surface.

 Bolt or clamp the saw to its support.

Place the saw in the desired location, either on a work

bench or recommended leg set. The base of the saw has

three mounting holes (1).

should fully close. Follow instructions in

TROUBLESHOOTING GUIDE for

adjustment if necessary.

 Other conditions that may affect the way the

miter saw works.

Keep all guards in place, in working order and properly

adjusted.

If any part of this miter saw is missing, bent

damaged or broken in any way, or any electrical

parts don’t work, turn the saw off and unplug it.

Replace damaged, missing, or defective parts

before using the saw again.

 Maintain tools with care. Keep the miter saw

clean for best and safest performance. Follow

instructions for lubricating. Don’t put lubricants on

the blade while it’s spinning.

 Remove all adjusting wrenches from the tool

before turning it on.

USE ONLY RECOMMENDED ACCESSORIES

 Consult the ACCESSORIES and ATTACHMENTS

section of this Operators Manual for

recommended accessories. Follow the

instructions that come with the accessory. The

use of improper accessories may cause risk of

injury to persons.

 Choose the correct 10 inch diameter blade for the

material and the type of cutting you plan to do. Do

not use Thin Kerf blades.

 Make sure the blade is sharp, undamaged and

properly aligned. With the saw unplugged, push

the cutting arm all the way down. Manually spin

the blade and check for clearance. Tilt the miter

head to a 45° bevel and repeat the test.

 Make sure the blade and arbor collars are clean.

 Make sure all clamps and locks are tight and

there is no excessive play in any parts.

KEEP YOUR WORK AREA CLEAN

Cluttered areas and benches invite accidents.

To avoid burns or other fire damage, never use the

miter saw near flammable liquids, vapors, or gases.

 Plan ahead to protect your eyes, hands, face

and ears.

 Know your miter saw.

Read and understand the Operator’s Manual and

labels affixed to the tool. Learn its application and

limitations as well as the specific potential hazards

specific to this tool. To avoid injury from accidental

contact with moving parts, don’t do layout, assembly,

or setup work on the miter saw.

 Avoid accidental starting

Make sure the switch is OFF before plugging the

miter saw into a power outlet.

15

PLAN YOUR WORK

 Use the right tool. Don’t force a tool or attachment

to do a job it was not designed to do. Use a

different tool for any workpiece that can’t be held

in a solidly braced, fixed position.

CAUTION: This machine is NOT designed for cutting

masonry, masonry products & ferrous metals (steel,

iron, and iron-based metals.) Use this miter saw to cut

only wood and wood by-products. Other material may

shatter, bind the blade, or create other dangers.

Remove all nails that may be in the workpiece to

prevent sparking that could cause a fire.

DRESS FOR SAFETY

Any power tool can throw foreign objects into the eyes.

This can result in permanent eye damage. Everyday

eyeglasses have only impact resistant lenses and are

not safety glasses. Glasses or goggles not in

compliance with ANSI Z87.1 could seriously injure you

when they break.

 Do not wear loose clothing, gloves, neckties or

jewelry (rings, watches). They can get caught and

draw you into moving parts.

 Wear non-slip footwear.

 Tie back long hair.

 Roll long sleeves above the elbow.

 Noise levels vary widely. To avoid possible

hearing damage, wear ear plugs when using any

miter saw.

 For dusty operations, wear a dust mask along

with safety goggles.

INSPECT YOUR WORKPIECE

Make sure there are no nails or foreign objects in the

part of the workpiece being cut.

Plan your work to avoid small pieces that may bind,

or that are too small to clamp and get a solid grasp

on.

Plan the way you will grasp the workpiece from start to

finish. Avoid awkward operations and hand positions.

A sudden slip could cause your fingers or hand to

move into the blade.

DON’T OVER-REACH

Keep good footing and balance. Keep your face and

body to one side, out of the line of a possible kickback.

NEVER stand in the line of the blade.

Never cut freehand:

 Brace your workpiece firmly against the fence and

table stop so it will not rock or twist during the cut.

 Make sure there is no debris between the

workpiece and the table or fence.

 Make sure there are no gaps between the

workpiece, fence and table that will let the

workpiece shift after it is cut.

 Keep the cut off piece free to move sideways after

it is cut off. Otherwise, it could get wedged

against the blade and thrown violently.

 Only the workpiece should be on the saw’s table.

 Secure work. Use clamps or a vise to help hold

the work when it’s practical.

USE EXTRA CAUTION WITH LARGE OR ODD

SHAPED WORKPIECES.

 Use extra supports (tables, sawhorses, blocks,

etc.) for workpieces large enough to tip.

 Never use another person as a substitute for a

table extension, or as an additional support for a

workpiece that is longer or wider than the basic

miter saw table, or to help feed, support, or pull

the workpiece.

 Do not use this saw to cut small pieces. If the

workpiece being cut would cause your hand or

fingers to be within 7-1/4” inches of the saw blade

workpiece is too small. Keep hands and fingers

out of the “no hands zone” area marked on the

saws table.

 When cutting odd shaped workpieces, plan your

work so it will not bind in the blade and cause

possible injury. Molding, for example, must lie flat

or be held by a fixture or jig that will not let it move

when cut.

 Properly support round material such as dowel

rods, or tubing, which have a tendency to roll

when cut, causing the blade to “bite”.

To avoid injury, follow all applicable safety instructions,

when cutting non-ferrous metals:

 Use only saw blades specifically recommended

for non-ferrous metal cutting.

 Do not cut metal workpieces that must be hand

held. Clamp workpieces securely.

 Cut non-ferrous metals only if you are under the

supervision of an experienced person.

WHEN SAW IS RUNNING

Don’t allow familiarity from frequent use of your miter

saw to result in a careless mistake. A careless fraction

of a second is enough to cause a severe injury.

Before cutting, if the saw makes an unfamiliar noise or

vibrates, stop immediately. Turn the saw OFF. Unplug

the saw. Do not restart until finding and correcting the

problem.

16

TURNING THE SAW ON (Fig. Q)

To reduce the likelihood of accidental starting, a thumb

activated lock-OFF switch is located on top of the

switch handle. The safety lock-OFF button (1) must be

pushed forward before the trigger switch (2) can be

activated and the miter saw started.

Make the switch child-proof. Insert a padlock through

the hole (3) in the trigger switch and lock it. This will

prevent children and other unauthorized users from

turning the switch ON.

THE LASER -TRAC®

Your tool is equipped with our latest innovation,

the Laser -Trac®, a battery powered device using

Class IIIa laser beams. The laser beams will

enable you to preview the miter blade path on the

workpiece to be cut before you begin your

operation.

Laser is activated when blade is rotating. Do not stare

into beam or view directly with optical instruments. Do

not remove the warning label affixed to the blade

guard. Avoid direct eye contact with light source.

NOTE - The red laser line will appear as a dotted line

when the motor is activated and the blade assembly is

in the uppermost position. This broken line will assist

you in aligning the mark on your workpiece with the

cutting path of the saw blade. As you lower the blade

assembly, the retractable guard will lift and turn the

broken line into a solid red laser line.

Laser Warning label: Max output <5mW DIODE

LASER: 630-670nm, Complies with 21CFR 1040.10

and 1040. 11.

OPERATION OF LASER

With the blade assembly in the uppermost position:

1. Position your workpiece onto the miter saw.

2. Turn on the miter saw to activate the laser beam.

3. Verify the laser beam is aligned with the mark on

the workpiece (WARNING - Do not lower the blade

assembly during the alignment process).

4. If the mark on the workpiece is not aligned with the

dotted laser line, turn off machine, wait for the

blade to stop and reposition workpiece.

5. Turn on the miter saw and verify alignment.

6. Once alignment is achieved, secure workpiece

with a clamping device and perform the cut.

BODY AND HAND POSITION (FIG. P)

Proper positioning of your body and hands when

operating the miter saw will make cutting easier and

safer. Never place hands near the cutting area. Position

hands at least 7-1/4” away from the path of the blade.

Hold workpiece firmly against the fence to prevent

movement toward the blade. Keep hands in position

until the trigger has been released and the blade has

completely stopped. Before making a cut, with the

power switch in the OFF position bring the saw blade

down to the workpiece to see the cutting path of the

blade.

 Keep children away. Keep all visitors a safe

distance from the miter saw. Make sure

bystanders are clear of the miter saw and

workpiece.

 Don’t force tool. It will do the job better and safer

at its designed rate. Feed the saw into the

workpiece slowly with a firm downward motion.

 Before freeing jammed material:

 Turn switch OFF.

 Unplug the miter saw.

 Wait for all moving parts to stop.

 After finishing a cut, keep holding the upper

blade assembly in the down position.

 Release the switch, and wait for all moving

parts to stop before moving your hands.

 If the blade doesn’t stop within 6 seconds, unplug

the saw and follow the instructions in

TROUBLESHOOTING GUIDE section for

adjusting the blade brake before using the saw

turning the miter handle (1) counterclockwise. While

holding the miter handle, press down on the positive

stop locking lever (2). Rotate the miter table to the right

or left with the miter handle. When the table is in the

desired position as shown on the miter scale (3),

release the positive stop locking lever and tighten the

miter handle. The table is now locked at the desired

angle. Positive stops are provided at 0°,15°,22.5°,31.6°

and 45°.

IMPORTANT: Always tighten the miter table lock

handle before performing a cut.

Fig. R

BEVEL CUT (FIG. S)

When a bevel cut is required, loosen the bevel lock

handle (1). Tilt the cutting head to the desired angle as

shown on the bevel scale (2). The blade can be

positioned at any angle, from a 90° straight cut (0° on

the scale) to a 45° left bevel. Tighten the lock handle

(1) to lock the desired cutting head in position. Positive

stops are provided at 0 and 45°.

COMPOUND CUT (FIG. T)

A compound cut is the combination of a miter and a

bevel cut simultaneously.

1. Loosen the bevel lock handle (1) and position the

cutting head at the desired bevel position. Lock the

bevel lock handle.

2. Loosen the miter table lock handle (2). Press down

the positive stop locking lever (3) and position the

table at the desired angle. Release the positive

stop locking lever and lock the miter handle.

Fig. T

CUTTING BOWED MATERIAL (FIG. U)

A bowed workpiece must be positioned against the

fence and secured with a clamping devise before

cutting. Do not position workpiece incorrectly or try to

cut the workpiece without the support of the fence.

This will cause the blade to bind and could result in

personal injury.

Fig. U

Fig. S

18

WORKPIECE SUPPORT (FIG. V)

Long pieces need extra support. The support should

be placed under the workpiece. Keep your hands out

of the “no-hands” zone, positioned 7-1/4” or more

away from the blade. The support must let the

workpiece lay flat on the worktable during the cutting

operation.

NOTE: When mounted on a flat surface, the miter saw

table is 3-1/8 inches high.

Fig. V

AUXILARY WOOD FENCE (FIG. W)

When making multiple or repetitive cuts that result in

cut-off pieces of one inch or less, it is possible for the

saw blade to catch the cut-off piece and throw it out of

the saw or into the blade guard and housing, possibly

causing damage or injury. To minimize this an auxiliary

wood fence can be mounted to your saw.

Holes are provided in the saw fence to attach an

auxiliary wood fence. This fence is constructed of

straight auxiliary wood approximately 3/4 inch thick by

2-1/2 inches high by 18 inches long.

Attach the wood fence securely and make a full depth

cut to make a blade slot.

Check for interference between the wood fence and

the lower blade guard. Adjust if necessary.

NOTE: This auxiliary fence is used only with the saw

blade in the 0° bevel position (90° to the table). The

auxiliary wood fence must be removed when bevel

cutting.

WOOD FENCE” section is required.

Fig. Y

CUTTING BASE MOLDING (FIG. Z)

Base moldings and many other moldings can be cut

on a compound miter saw. The setup of the saw

depends on molding characteristics and applications,

as shown. Perform practice cuts on scrap material to

achieve best results:

1. Always make sure moldings rest firmly against fence

and table. Use hold-down or C-clamps, whenever

possible, and place tape on the area being clamped

to avoid marks.

2. Reduce splintering by taping the cut area prior to

making cut. Mark cut line directly on the tape.

3. Splintering typically happens due to wrong blade

application and thinness of the material.

Fig. Z

NOTE: Always perform a dry run cut so you can

determine if the operation being attempted is possible

before power is applied to the saw.

20

1

CUTTING CROWN MOLDING (FIG. AA, BB)

Your compound miter saw is suited for the difficult task

of cutting crown molding. To fit properly, crown molding

must be compound-mitered with extreme accuracy.

The two surfaces on a piece of crown molding that fit

flat against the ceiling and wall 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°.

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 saw table.

When setting the bevel and miter angles for compound

miters, remember that the settings are interdependent;

changing one changes the other, as well. Also keep in

mind that the angles from crown molding are very easy

for these angles to shift slightly, all settings should be

tested on scrap molding.

MAINTENANCE

MAINTENANCE

DANGER

Never put lubricants on the blade while it is spinning.

To avoid fire or toxic reaction, never use gasoline,

naphtha acetone, lacquer thinner or similar highly

volatile solvents to clean the miter saw.

To avoid injury from unexpected starting or electrical

shock, unplug the power cord before working on the

saw.

For your safety, this saw is double-insulated. To avoid

electrical shock, fire or injury, use only parts identical

to those identified in the parts list. Reassemble

exactly as the original assembly to avoid electrical

shock.

REPLACING CARBON BRUSHES (FIG. DD)

The carbon brushes furnished will last approximately

50 hours of running time, or 10,000 ON/OFF cycles.

Replace both carbon brushes when either has less

than 1/4” length of carbon remaining, or if the spring

or wire is damaged or burned. To inspect or replace

brushes, first unplug the saw. Then remove the black

plastic cap (1) on the side of the motor (2). Remove

the cap cautiously, because it is springloaded. Then

pull out the brush and replace. Replace for the other

side. To reassemble reverse the procedure. The ears

on the metal end of the assembly go in the same hole

the carbon part fits into. Tighten the cap snugly, but

do not overtighten.

NOTE: To reinstall the same brushes, first make sure

the brushes go back in the way they came out. This

will avoid a break-in period that reduces motor

performance and increase wear.

Fig. DD

LOWER BLADE GUARD

Do not use the saw without the lower blade guard.

The lower blade guard is attached to the saw for your

protection. Should the lower guard become damaged,

do not use the saw until the damaged guard has been

replaced. Develop a regular check to make sure the

lower guard is working properly. Clean the lower

guard of any dust or buildup with a damp cloth.

AUTION: Do not use solvents on the guard. They

could make the plastic “cloudy” and brittle.

When cleaning the lower guard, unplug the saw from

the power source receptacle to avoid unexpected

startup.

SAWDUST

Periodically, sawdust will accumulate under the work

table and base. This could cause difficulty in the

movement of the worktable when setting up a miter

cut. Frequently blow out or vacuum up the sawdust.

If blowing sawdust, wear proper eye protection to

keep debris from blowing into eyes.

LUBRICATION

All the motor bearings in this tool are lubricated with a

sufficient amount of high grade lubricant for the life of

the unit under normal operating conditions; therefore,

no further lubrication is required.

Lubrication the Following as Required:

Chop pivot: light machine oil or aerosol will penetrate

from the ends of the junction points. A qualified

service technician can remove the pivot upstop to

relieve tension, and the 2 metric set screws holding

the shaft, in order to drive the shaft about 3/4” right.

Exposed surfaces are lubricated with automotive type

oil.

Central pivot of plastic guard: Use light household oil

(sewing machine oil ) on metal-to–metal or

metal-to-plastic guard contact areas as required for

smooth, quiet operation. Avoid excessive oil, to which

sawdust will cling.

Link: (which actuates the lower guard movement)

may be oiled at the rear pivot, greased at ball bearing

contact, and oiled where the link actuates the acetyl

roller of the lower guard, if the down chop motion is

hard to start.
