SA VE ALL W ARNINGS AND

INSTRUCTIONS FOR FUTURE

The term “power tool” in the warnings

REFERENCE

refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1) WORK AREA SAFETY a) Keep work area clean and well

lit. Cluttered or dark areas invite

accidents.

b) Do not operate power tools in explosive atmospheres, such

as in the presence of ammable

liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

c) Keep children and bystanders

away while operating a power tool.

Distractions can cause you to lose

control.

2) ELECTRICAL SAFETY a) Power tool plugs must match the

outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodied plugs and

matching outlets will reduce risk of electric shock.

b) Avoid body contact with earthed

or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased

risk of electric shock if your body is earthed or grounded.

c) Do not expose power tools to rain

or wet conditions. Water entering

a power tool will increase the risk of electric shock.

d) Do not abuse the cord. Never use

the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged

or entangled cords increase the risk of electric shock.

e) When operating a power tool

outdoors, use an extension cord suitable for outdoor use. Use

of a cord suitable for outdoor use reduces the risk of electric shock.

f) If operating a power tool in damp

location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of

a GFCI reduces the risk of electric shock.

3) PERSONAL SAFETY a) Stay alert, watch what you are

doing and use common sense when operating a power tool. Do not use a power tool while you

are tired or under the inuence

of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

b) Use personal protective

equipment. Always wear eye protection. Protective equipment

such as dust mask, nonskid safety shoes, hard hat, or hearing

Page 3

protection used for appropriate conditions will reduce personal injuries.

c) Prevent unintentional starting.

Ensure the switch is in the off position before connecting to power source and/ or battery

pack, picking up or carrying the tool. Carrying power tools with your

nger on the switch or energizing

power tools that have the switch on invites accidents.

d) Remove any adjusting key or

wrench before turning the power tool on. A wrench or a key left

attached to a rotating part of the power tool may result in personal injury.

e) Do not overreach. Keep proper

footing and balance at all times.

This enables better control of the power tool in unexpected situations.

f) Dress properly. Do not wear loose

clothing or jewelry. Keep your hair, clothing and gloves away from moving parts. Loose clothes,

jewelry or long hair can be caught in moving parts.

g) If devices are provided for the

connection of dust extraction and collection facilities, ensure these are connected and properly used.

Use of dust collection can reduce dust-related hazards.

4) POWER TOOL USE AND CARE a) Do not force the power tool. Use

the correct power tool for your application. The correct power tool

will do the job better and safer at the rate for which it was designed.

b) Do not use the power tool if the

switch does not turn it on and off. Any power tool that cannot

be controlled with the switch is dangerous and must be repaired.

c) Disconnect the plug from the

power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety

measures reduce the risk of starting the power tool accidentally.

d) Store idle power tools out of

the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power

tools are dangerous in the hands of untrained users.

e) Maintain power tools. Check

for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many

accidents are caused by poorly maintained power tools.

f) Keep cutting tools sharp and

clean. Properly maintained cutting

tools with sharp cutting edges are less likely to bind and are easier to control.

g) Use the power tool, accessories

and tool bits, etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool

for operations different from those intended could result in a hazardous situation.

5) SERVICE a) Have your power tool serviced by

a qualied repair person using

only identical replacement parts.

This will ensure that the safety of the power tool is maintained.

ADDITIONAL SAFETY RULES FOR MITER SAWS

WARNING

(gained from frequent use of your saw) to replace safety rules. Always remember that a careless fraction of

a second is sufcient to inict severe

injury.

• DO NOT OPERATE THIS MACHINE until it is completely assembled and installed according to the instructions. A machine incorrectly assembled can cause serious injury.

• OBTAIN ADVICE from your supervisor,

instructor, or another qualied person if

you are not thoroughly familiar with the operation of this machine. Knowledge is safety.

• STABILITY. Make sure the miter saw is placed on a secure supporting surface and does not slip or move during use.

• FOLLOW ALL WIRING CODES and recommended electrical connections

to prevent shock or electrocution.

Protect electric supply line with at least a 15 ampere time-delay fuse or

a circuit breaker.

• MAKE CERTAIN the blade rotates in the correct direction. The teeth on the blade should point in the direction of rotation as marked on the saw.

Do not allow familiarity

Page 4

• TIGHTEN ALL CLAMP HANDLES, knobs and levers prior to operation. Loose clamps can cause parts or the workpiece to be thrown at high speeds.

• BE SURE all blade and blade clamps are clean, recessed sides of blade clamps are against blade and arbor screw is tightened securely. Loose or improper blade clamping may result in damage to the saw and possible personal injury.

• ALWAYS USE A SHARP BLADE. Check the blade to see if it runs true and is free from vibration. A dull or a vibrating blade can cause damage to

the machine and/or serious injury.

• DO NOT OPERATE ON ANYTHING OTHER THAN THE DESIGNATED VOLTAGE for the saw. Overheating,

damage to the tool and personal injury may occur.

• DO NOT WEDGE ANYTHING AGAINST THE FAN to hold the motor shaft. Damage to tool and possible personal injury may occur.

• DO NOT FORCE CUTTING ACTION. Stalling or partial stalling of motor can cause damage to the machine or blade

and/or serious injury.

• ALLOW THE MOTOR TO COME TO FULL SPEED prior to starting cut.

Starting the cut too soon may cause

damage to the machine or blade and/or

serious injury.

• NEVER CUT METALS or masonry. Either of these can cause the carbide

tips to y off the blade at high speeds

causing serious injury.

• DO NOT USE ABRASIVE WHEELS. The excessive heat and abrasive particles generated by them may damage the saw and cause personal injury.

• NEVER HAVE ANY PART OF YOUR

BODY IN LINE WITH THE PATH OF THE SAW BLADE. Personal injury will

occur.

• NEVER APPLY BLADE LUBRICANT TO A RUNNING BLADE. Applying lubricant could cause your hand to move into the blade resulting in serious injury.

• DO NOT place either hand in the blade area when the saw is connected to the power source. Inadvertent blade activation may result in serious injury.

• DO NOT PERFORM FREEHAND OPERATIONS (workpiece not supported by table and fence). Hold the

work rmly against the fence and table.

Freehand operations on a miter saw

could cause the workpiece to be thrown

at high speeds, causing serious injury.

• NEVER REACH AROUND OR BEHIND THE SAW BLADE. A blade can cause serious injury.

• DO NOT REACH UNDERNEATH THE SAW unless it is unplugged and turned off. Contact with saw blade may cause personal injury.

• SECURE THE MACHINE TO A STABLE SUPPORTING SURFACE. Vibration can possibly cause the machine to slide, walk, or tip over, causing serious injury.

• USE ONLY CROSSCUT SAW BLADES recommended for miter saws. For best results, do not use carbide tipped blades with hook angles in excess of 7 degrees. Do not use blades

with deep gullets. These can deect

and contact the guard, and can cause

damage to the machine and/or serious

injury.

• USE ONLY BLADES OF THE

CORRECT SIZE AND TYPE specied

for this tool to prevent damage to the

machine and/or serious injury.

• INSPECT BLADE FOR CRACKS or other damage prior to operation. A cracked or damaged blade can come apart and pieces can be thrown at high speeds, causing serious injury. Replace cracked or damaged blades immediately.

• CLEAN THE BLADE AND BLADE CLAMPS prior to operation. Cleaning the blade and blade clamps allows you to check for any damage to the blade or blade clamps. A cracked or damaged blade or blade clamp can come apart and pieces can be thrown at high speeds, causing serious injury.

• DO NOT use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the plastic guard. The plastic material used in the guard is subject to attack by certain chemicals.

• ALWAYS USE THE KERF PLATE

AND REPLACE THIS PLATE WHEN DAMAGED. Small chip accumulation

under the saw may interfere with the saw blade or may cause instability of workpiece when cutting.

• USE ONLY BLADE CLAMPS SPECIFIED FOR THIS TOOL to

prevent damage to the machine and/or

serious injury.

• CLEAN THE MOTOR AIR SLOTS of chips and sawdust. Clogged motor air slots can cause the machine to overheat, damaging the machine and

Page 5

possibly causing a short which could

cause serious injury.

• KEEP ARMS, HANDS, AND FINGERS AWAY FROM THE BLADE to prevent severe cuts. Clamp all workpieces that would cause your hand to be within 6" (152 mm) of the saw blade.

• NEVER LOCK THE SWITCH IN THE “ON” POSITION. Severe personal injury may result.

• TURN OFF THE MACHINE and allow the blade to come to a complete stop before raising the arm and prior to cleaning the blade area, removing debris in the path of the blade, before servicing or adjusting tool. A moving blade can cause serious injury.

• PROPERLY SUPPORT LONG OR WIDE WORKPIECES. Loss of control of the workpiece can cause injury.

• NEVER CROSS ARMS IN FRONT OF BLADE while using tool. Always make a dry run (unpowered) before making

a nish cut so that you can check the

path of the blade or severe personal injury may result.

ELECTRICAL REQUIREMENTS AND SAFETY

POWER SUPPLY AND MOTOR SPECIFICATIONS

The AC motor used in this saw is a universal, nonreversible type.

WARNING

hazards, re hazards, or damage to the

tool, use proper circuit protection. Your saw is wired at the factory for 120 V operation. Connect to a 120 V, 9 A circuit and use a 9 A time delay fuse or circuit breaker. To avoid shock

or re, if power cord is worn or cut, or

damaged in any way, have it replaced immediately.

ELECTRICAL REQUIREMENTS 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:

Polarized plugs

To reduce the risk of electrical shock, this saw has a polarized plug (one blade

is wider than the other). This plug will t

in a polarized outlet only one way. If the

plug does not t fully in the outlet, reverse the plug. If it still does not t, contact a qualied electrician to install the proper

outlet. Do not change the plug in any way.

To avoid electrical

WARNING

not take the place of normal safety precautions when operating this tool.

To avoid electrocution:

• Use only identical replacement parts

when servicing a tool with double insulation. Servicing should be

performed by a qualied technician.

• 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.

• Connect this saw to a 120 V, 9 A circuit

with a 9 A time-delay fuse or circuit breaker. Using the wrong size fuse can damage the motor.

• If the motor will not 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.

• 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 nished.

• FUSES may “blow” or circuit breakers

may trip frequently if:

• MOTOR is overloaded – overloading can occur if you feed too rapidly or

make too many start/stops in a short

time.

• 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 specied on the

nameplate.

• IMPROPER or dull saw blades are used.

Double insulation does

Page 7

• 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 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 qualied 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 a #18 wire with a 9 A time lag fuse. NOTE: When using an extension cord on a circuit with a #18 wire, the extension cord must not exceed 25 feet in length. 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.

• Be sure the arbor lock button (4) is released so the blade turns freely by spinning the blade until the arbor lock disengages.

(Figure H)

WARNING

• To avoid injury, never use the saw

without the cover plate secure in place. It keeps the arbor bolt from falling out if it accidentally loosens, and helps prevent the spinning blade from coming off the saw. It also keeps the guard from contacting a spinning blade.

• Make sure the collars are clean and

properly arranged. Lower the blade into the table and check for any contact with the metal base or the turn table.

MOUNTING THE MITER SAW (FIGURE J, K)

WARNING

To avoid injury form

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 hold-down latch.

miter saw.

BEFORE EACH USE INSPECT YOUR SAW

• Disconnect the miter saw. To avoid injury from accidental starting, unplug the saw before any adjustments, including set-up and blade changes.

Page 19

• Compare the direction of rotation arrow on the guard to the direction

arrow on the blade. The blade teeth should always point downward at the front of the saw.

• Tighten the arbor bolt.

• Tighten the cover plate screw.

• Check for damaged parts. Check for:

• Alignment of moving parts

• Damaged electric cords

• Binding of moving parts

• Mounting holes

• Function of arm return spring and lower guard: Push the cutting arm all the way down, then let it rise until it stops. The lower guard should fully close. Follow instructions in TROUBLESHOOTING for adjustment

if necessary.

• Other conditions that may affect the way the miter saw works.

• Keep all guards in place, in working order and proper adjustment. If any part of this miter saw is missing, bent, damaged or broken in any way, or any electrical parts do not work, turn the saw off and unplug it.

• Replace bent, 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. Do not put lubricants on the blade while it is spinning.

• Remove adjusting wrench from the tool before turning it on.

• To avoid injury from jams, slips, or thrown pieces, use only recommended accessories.

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 7-1/4 in. diameter blade (with a 5/8 inch round arbor hole,

and no more that 7 degree hook angle) 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 power-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.

WARNING

To avoid burns or other

re damage, never use the miter saw near ammable liquids, vapors, or

gases.

• Plan ahead to protect your eyes, hands, face and ears.

• Know your miter saw. Read and understand the Instruction Manual

and labels afxed to the tool. Learn

its application and limitations as well

as the specic potential hazards

peculiar to this tool. To avoid injury from accidental contact with moving parts, do not do layout, assembly, or setup work on the miter saw while any parts are moving.

• Avoid accidental starting, make sure the trigger switch is disengaged before plugging the miter saw into a power outlet.

PLAN YOUR WORK

• Use the right tool. Do not 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, xed position.

Page 20

CAUTION

This machine is not designed for cutting masonry, masonry products, metals. Use this miter saw to cut only wood, or wood-like 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 re. Remove dust bag when cutting

non-ferrous metals.

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 nish. Avoid awkward operations and

hand positions. Keep your hands at least 6 inches away from the blade path.

A sudden slip could cause your ngers

or hand to move into the blade.

WARNING

TO ENSURE THE BLADE PATH IS CLEAR OF OBSTRUCTIONS, ALWAYS MAKE A DRY RUN OF THE CUT WITHOUT POWER BEFORE MAKING ANY CUTS ON THE WORKPIECE.

DO NOT 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 rmly 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

saws table.

• Secure work. Use clamps or a vise to

help hold the work when it is 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 ngers to be within 6 in.

of the saw blade the workpiece is too

small. Keep hands and ngers 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 at or be held by a xture or jig that will not let it

move when cut.

Page 21

• Properly support round material such as dowel rods, or tubing, which have a tendency to roll when cut, causing the blade to “bite”. This is especially important when making angle cuts.

• NEVER tie, tape or hold the guard open when operating the saw.

WARNING

A workpiece that is clamped, balanced and secure before a cut may become unbalanced after a cut is completed. An unbalanced load may tip the saw or anything the saw is attached to, such as a table or workbench. When making a cut that may become unbalanced, properly support the workpiece and ensure the

saw is rmly bolted to a stable surface.

Personal injury may occur.

WARNING

The clamp foot must remain clamped above the base of the saw whenever the clamp is used. Always clamp the workpiece to the base of the saw – not to any other part of the work area. Ensure the clamp foot is not clamped on the edge of the base of the saw.

CAUTION

Always use a work clamp to maintain control and reduce the risk of workpiece damage and personal injury.

WHEN SAW IS RUNNING

WARNING

Do not 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 nding and correcting

the problem.

BODY AND HAND POSITION (FIGURE R, S, T, U, V)

WARNING

Never place hands near the cutting

area. Proper positioning of your body and hands when operating the miter saw will make cutting easier and safer. Keep children away. Keep all visitors at a safe distance from the miter saw. Make sure bystanders are clear of the saw and workpiece. Do not force the saw. It will do the job better and safer at its designed rate.

ALWAYS MAKE DRY RUNS (UNPOWERED) BEFORE FINISH CUTS SO THAT YOU CAN CHECK THE PATH OF THE BLADE. DO NOT CROSS HANDS, AS SHOWN IN FIGURE R, S, T & U.

BASIC SAW OPERATIONS

WARNING

Never connect the plug to the power source outlet until all installations and adjustments are completed and you have read and understood the safety and operational instructions.

Starting a cut:

• Place hands at least 6 in. away on both sides of the blade path - “no-hands zone (1)”. (Figure V)

• Hold workpiece rmly against the fence

to prevent movement toward the blade.

• With the power switch OFF, bring the saw blade down to the workpiece to see the cutting path of the blade.

• Squeeze trigger switch to start saw.

• Lower blade into workpiece with a rm

downward motion.

Finishing a cut:

• Hold the cutting arm in the down position.

• Release trigger switch and wait for all moving parts to stop before moving your hands and raising the cutting arm.

• Unplug the miter saw.

Before freeing jammed material:

• Release trigger switch.

• Wait for all moving parts to stop.

• Unplug the miter saw.

TURNING THE SAW ON (FIGURE W)

• To reduce the likelihood of accidental starting, a thumb activated lock-off switch is located on top of the switch handle. The lock-off switch (1) must

be pushed in before the trigger switch (2) can be activated and the

miter saw started.

NOTE: To make the ON/OFF trigger switch

childproof, insert a padlock (not provided) or chain with padlock through the hole (3) in the trigger switch. Lock the tool’s switch

to prevent children and other unqualied

users from turning the machine on.

Page 23

BEFORE LEAVING THE SAW

• Never leave tool running unattended. Turn power OFF. Wait for all moving parts to stop.

• Make workshop childproof. Lock the shop. Disconnect master switches. Store tool away from children and other

unqualied users.

WARNING

To avoid injury from materials being thrown, always unplug the saw to avoid accidental starting, and remove small pieces of material from the table cavity.

MITER CUT (FIGURE X)

• When a miter cut is required, unlock the miter table locking lever (1).

• Hold the base of saw arm to move the table to the desired angle.

• When the table is in the desired position, as shown on the miter scale (2), tighten the miter table locking lever. The table is now locked at the desired angle. Positive stops are provided at 0°, 15°,

22.5°, 31.6° and 45° left and right.

IMPORTANT: Always tighten the miter

table locking lever before performing every cutting operation.

COMPOUND CUT (FIGURE Z)

A compound cut is the combination of a miter and a bevel cut simultaneously.

• Loosen the bevel lock handle and position the cutting head at the desired bevel position. Lock the bevel lock handle. See "BEVEL CUT."

• Loosen the miter table locking lever and position the table at the desired angle. Lock the miter table locking lever. See "MITER CUT."

BEVEL CUT (FIGURE Y)

• 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 bevel lock handle (1) to lock the cutting head in position. Positive stops are provided at 0° and 45°.

CUTTING BOWED MATERIAL (FIGURE AA) To avoid injury from

WARNING

materials being thrown, always unplug the saw to avoid accidental starting and remove small pieces of material from the table cavity.

• The table insert may be removed for this purpose, but always reattach table insert prior to performing a cutting operation.

• A bowed workpiece (1) must be positioned against the fence and secured with a clamping device (2) as shown 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.

Page 24

WORKPIECE SUPPORT (FIGURE BB)

Long pieces need extra support. The support should be placed under the workpiece. Keep your hand holding the

workpiece positioned 6-3/4 inches or more

away from the blade. The support must

let the workpiece lay at on the work table

during the cutting operation.

NOTE: When mounted on a at surface, the saw table is 2-4/5 inches high.

2-4/5 in.

CUTTING CROWN MOLDING (FIGURE DD, EE)

Your compound miter saw is suited for

the difcult task of cutting crown molding. To t properly, crown molding must be

compound-miterd with extreme accuracy. The two surfaces on a piece of crown

molding that t at 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 ts at against

the ceiling) of 52°and a bottom rear

angle (the section that ts at against

the wall) of 38°.

CUTTING BASE MOLDING (FIGURE CC)

Base moldings and many other moldings can be cut on a compound miter saw. The setup of the saw depends on molding characteristics and application, as shown. Perform practice cuts on scrap material to achieve best results:

• Always make sure moldings rest rmly

against fence and table. Use hold-down,

crown molding vise or C-clamps,

whenever possible, and place tape on the area being clamped to avoid marks.

• Reduce splintering by taping the cut area prior to making the cut. Mark the cut line directly on the tape.

• Splintering typically happens due to an incorrect blade application and thinness of the material.

In order to accurately cut crown molding for a 90° inside or outside corner, lay the molding with its broad

back surface at 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.

MAINTENANCE

WARNING

•

DO NOT touch the sharp points on

the blade with ngers or hands while

performing any maintenance.

DANGER

•

To avoid injury, never put lubricants on the blade while it is spinning.

•

DO NOT use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the plastic guard. The plastic material used in the guard is subject to attack by certain chemicals.

WARNING

•

To avoid re 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,

re or injury, use only parts identical to those identied in the parts list.

Reassemble exactly as the original assembly to avoid electrical shock.

REPLACING CARBON BRUSHES (FIGURE FF)

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 in. length of carbon remaining, or if

the spring or wire is damaged or burned.

To inspect or replace brushes, rst unplug

the saw. Then remove the 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 ts into. Tighten the

cap snugly, but do not overtighten. Repeat for the carbon brush located on the other side of motor. NOTE: To reinstall the same brushes,

rst make sure the brushes go back in

exactly the way they came out. This will avoid a break-in period that reduces motor performance and increases wear.

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.

WARNING

• When cleaning the lower guard,

unplug the saw from the power source receptacle to avoid unexpected startup.

•

Do not use solvents on the guard. They could make the plastic “cloudy” and brittle.

SAWDUST

Periodically, sawdust will accumulate under the work table and base. This

could cause difculty in the movement

of the worktable when setting up a miter cut. Frequently blow out or vacuum up the sawdust.

Page 29

To empty the dust bag, remove the sawdust bag from the dust collection port. Open the zipper on the sawdust bag and empty out the sawdust inside. Close the zipper and reinstall the dust bag as described on page 13.

WARNING

Wear proper eye protection to keep debris from entering eyes when removing sawdust from unit.

LUBRICATION (FIGURE GG)

All the motor bearings in this tool are

lubricated with a sufcient amount of

high grade lubricant for the life of the unit under normal operating conditions; therefore, no further bearing lubrication is required.

Lubricate the following as necessary:

Chop pivot (1):

points indicated in illustration.

Apply light machine oil to
