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

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

• 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

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

• 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.
