Keep your work area clean and well lit. Cluttered work benches and dark work areas may cause accidents or injury.
Do not operate power tools in explosive areas, such as in the presence of flammable liquids, gases or dust. Power tools create
sparks which may ignite the dust or fumes.
Keep bystanders, children and visitors away while operating a power tool. Distractions can cause you to lose control.
Double insulated tools are equipped with 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 a polarized outlet. Do not change the plug in any way. Double insulation eliminates the need for the three wire
grounded power cord and grounded power supply system.
Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of
electric shock if your body is grounded.
Do not abuse the cord. Never use the cord to carry the tool or pull the plug from an outlet. Keep the cord away from heat, oil,
sharp edges, or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.
When operating the tool outside, use an outdoor extension cord marked “WA” or “W.” These cords are rated for outdoor use
and reduce the risk of electric shock. Make sure the extension cord being used is in good condition. If there are any cuts or nicks (no
matter how deep) in the insulation, DO NOT use that cord. Also, make sure the extension cord is heavy enough to carry the current
needed. DO NOT use small "around-the-house” lamp extension cords. These cords can easily overheat and/or catch fire when used
with power tools.
Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is
designed.
Do not use the tool if the power switch does not turn it “ON” or “OFF”. Any tool that cannot be controlled with the switch is
dangerous and must be repaired.
Disconnect the power cord plug from the power source before making any adjustments, changing accessories or storing the
tool. Such preventive safety measures reduce the risk of starting the tool accidentally.
Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
People with pacemakers or other electronic devices should consult with a physician before operating this product. Interruption
or failure of the pacemaker could occur when electrical equipment is operated within close proximity of electrical devices.
Wash hands after handling the power cord. Touching the power cord could expose you to lead, which is known in the State of
California to cause cancer, birth defects and other reproductive harm.
All work areas should be clean and well lit. Accidents are more likely to occur in poorly lit and cluttered areas.
Keep children, and other distractions at a distance while operating power tools.

Keep the power cord in good condition, and replace damaged cords immediately. Do not use the cord to pull the plug from the
outlet. Keep the cord away from materials and surfaces that could damage cords. The risk of electric shock increases when the power
cord is damaged.
Always use the appropriate extension cord, making sure it is rated for use with power tools. Always be sure the extension cords
are in good condition, free of cuts or nicks in the insulation. If using the power tool in an outside area with an extension cord, make sure
the cord is rated for outdoor use.

Feeling tired or are under the influence of alcohol or drugs.
Wearing loose clothing or jewelry. Keep long hair pulled back and away from moving parts.
Overreaching or have improper footing. Handling the tool in this way could cause serious injury.
When using this power tool always:
•
•
•
Wear the proper safety equipment, such as safety goggles, dust masks, non-skid shoes, etc.
Check to be sure all adjusting keys or wrenches have been removed before starting the power tool.
Check to be sure the power switch is in the “OFF” position before plugging the power tool into an electrical outlet.
Follow these steps to maintain safe working conditions and good working condition of power tools. Improper care can result in
electric shock or serious injury.
•
•
•
Secure and support the work piece using clamps. Do not use your hands to hold the piece in place.
Use the correct tool for the job. Using the correct tool is safer and faster.

discontinue use, and have the tool replaced or repaired.
•
•
•
Remove the power cord from the power source before storage, changing accessories, or moving the tool.
Keep out of reach of children, or any untrained person. Store tools in a safe and dry place.
Keep tools clean, and cutting tools sharp. Maintaining tools with proper care will increase the life of the power tool, and
reduce the risk of injury.
•
•
•
Check to be sure all moving parts are free from binding and are properly aligned.
Use only accessories that are recommended by the manufacturer for your tool model.
Hold the tool by the insulated grip when using in an area where contact with a “live” wire is a possibility.

OPERATION
MAKING A STRAIGHT CUT
Unpack product from package and review contents. Keep all packaging until product has been reviewed.
Connect the miter saw to the outlet and make sure the cable is clear of the saw blade and base plate.
Place the material (A, Figure 2) on the machine bed and place it tight against the straight guide,
assuring that it doesn’t move during the cut. If necessary, use clamps to hold it in place.
Press the trigger on the handle to start the motor, allowing the saw blade to run up to full speed before
cutting.
A
Once the blade has reached full speed, move the saw blade down into the material, exerting only
enough pressure to cut. Let the saw do the work. Excessive pressure may damage the saw and may
lead to personal injury should the material or saw break.

MAKING MITER CUTS, BEVEL CUTS, AND COMPOUND CUTS
To make miter cuts, loosen the two rotary table-locking knobs (A)
and move the rotary table to the desired angle, then retighten the
knobs. Figure 2 shows the rotary table at a 45º angle.
Bevel cuts are achieved by moving the saw from a normal 90º
perpendicular position down to a 45º angle from the horizontal
position.
A
Turn the Head Tilt Clamping Knob (A, Figure 3) and tilt the saw
head to the desired angle and retighten the knob.
NOTE: Bevel cuts can only be made to the left only. (Figure 4)
A
Using the miter and bevel cutting feature simultaneously makes
compound angle cuts possible.

D
To confirm the 0º rotary table setting, set the rotary table at 0º.
Check the angle between the straight guide and blade to
ensure it is 90º by using a speed square (not included). If the
angle requires adjustment, loosen the straight guide clamp
screws (A, Figure 6) and align the straight guide against the
speed square before retightening.
A
B
Figure 6
Figure 7
Check the angle of the blade to the face of the rotary table to
confirm it is 90º. If necessary, adjust the angle by adjusting the
setscrew (A, Figure 7). When the proper angle is achieved,
tighten the locknut (B, Figure 7).
Use a 45º-miter gauge or set square to check the accuracy of the tilt angle. If necessary, loosen the setscrew (C, Figure 7), adjust to the correct
angle, and then tighten the locknut (D, Figure 7).

TIPS TO AVOID KICKBACK
Be prepared for kickback when using the saw. Kickback may cause the saw to jump backwards, and cause serious injury to the user.
Using the saw to cut imperfect, wet or warped material may cause kickback.
Kickback can occur when the saw blade becomes misaligned, pinched or bound, which causes the saw to lift up and out of the work piece, and
move toward the operator. Using the tool correctly can reduce the risk of kickback. Observe the following procedures to reduce the risk of
kickback:
●
When the saw blade becomes bound, or the cut begins to be interrupted, release the trigger & hold the saw in place until the saw blade
stops moving.
●
●
●
When restarting a cut in the work piece, center the saw blade in the cut, and make sure it is NOT touching the work piece.
Do not begin the cut until the saw blade has reached its full speed.
Always support large pieces of material with saw horses or clamps. Large pieces can sag under their own weight, and can cause the
saw blade to bind while making the cut.
●
Always use new saw blades. Old or damaged saw blades may cause excessive friction on the work piece, and increase the risk of
kickback.
●
●
Do not make saw blades adjustments during the cut. Check that the bevel and depth adjustments are set and secure before beginning.
Cut depth should always be set for no more than 1/8" to 1/4" larger than the thickness of the material to be cut. Always expose as little
of the saw blade as possible.
MAINTENANCE
Disconnect the power supply before cleaning. Wear safety eyewear before cleaning. Used compressed dry air to blow off dust and
debris. Use a soft bristle brush if compressed air is not available.
Applying excessive force to the tool can overload the motor, decrease the life and increase the wear on the tool.
Some chemicals can damage the product. Do not use harsh chemicals such as gasoline, carbon tetrachloride, paint thinner, etc. to
clean this product.
A qualified repair technician must perform any tool service or repair. Service or maintenance performed by unqualified personnel could
result in injury. Use only identical replacement parts. Use of unauthorized parts or failure to follow maintenance instructions may create a risk
of electric shock or injury.
Do not make contact with a grounded surface while using this power tool. Contact with surfaces like pipes, radiators or major appliances
increases your risk of electric shock.
Keep the air vents unclogged to prevent overheating. Remove dust and debris from the machine on a regular basis. Lubricate all moving
parts on a regular basis. Never use caustic agents to clean this machine.
ACCESSORIES
Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool
may become hazardous when used on another tool.
If you must use an extension cord, be sure that the gauge is large enough to carry the amount of current necessary for your
power tool. If not, your tool may experience a loss of power, excessive voltage drop or overheating. The smaller the gauge number, the
heavier the cord.
