GENERAL SAFETY RULES
WARNING! Read all instructions
Failure to follow all instructions listed below may result in electric shock,
re, and/or serious injury. The term “power tool” in all of the warnings listed
below refers to your line-operated (corded) power tool or battery-operated
(cordless) power tool.

WORK AREA
1.
2.
Keep your work area clean and well lit. Cluttered benches and dark areas
invite accidents.
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 ammables.

Grounded tools must be plugged into an outlet properly installed and
grounded in accordance with all codes and ordinances. Never remove the
grounding prong or modify the plug in any way. Do not use any adapter
plugs. Check with a qualied electrician if you are in doubt as to whether
the outlet is properly grounded. If the tools should electrically malfunction or
break down, grounding provides a low resistance path to carry electricity away
from the user.
Double insulated tools are equipped with 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 qualied 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 expose power tools to rain or wet conditions. Water entering a power
tool will increase the risk of electric shock.

Do not abuse the Power Cord. Never use Power Cord to carry the tools or
pull Plug from an outlet. Keep the Power Cord away from heat, oil, sharp
edges, or moving parts. Replace damaged Power Cords immediately.
Damaged Power Cords increase the risk of electric shock.
When operating a power tool outside, use an outdoor extension cord
marked “W-A” or “W”. These extension cords are rated for outdoor use, and
reduce the risk of electric shock.
PERSONAL SAFETY
Stay alert. Watch what you are doing, and use common sense when
operating a power tool. Do not use a power tool while tired or under the
inuence of drugs, alcohol, or medication. A moment of inattention while
operating power tools may result in serious personal injury.
Dress properly. Do not wear loose clothing or jewelry. Contain long
hair. Keep your hair, clothing, and gloves away from moving parts. Loose
clothes, jewelry, or long hair can be caught in moving parts.

Remove adjusting keys or wrenches before turning the power tool on. A
wrench or a key that is left attached to a rotating part of the power tool may result
in personal injury.
Do not overreach. Keep proper footing and balance at all times. Proper
footing and balance enables better control of the power tool in unexpected
situations.
Use safety equipment. Always wear ANSI approved safety glasses
underneath a full face shield, a dust mask or respirator, and hearing
protection.
TOOL USE AND CARE
Use clamps or other practical ways to secure and support the workpiece to
a stable platform. Holding the work by hand is unstable and may lead to loss of
control. Only work on a workpiece that is properly secured.
Do not force the 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 power tool if the Power Switch does not turn it on or off.
Any tool that cannot be controlled with the Power Switch is dangerous and must
be replaced.

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.
Maintain tools with care. Do not use a damaged tool. Tag damaged tools “Do
not use” until repaired.
Check for misalignment or binding of moving parts, breakage of parts,
cracking or breakage of the Saw Blade, and any other condition that may
affect the tool’s operation. If damaged, have the tool serviced before using.
Many accidents are caused by poorly maintained tools.
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.

Keep all guards in place and in working order. Never remove or disable
guards.
Remove all adjusting wrenches from the Miter Saw before turning it on.
Do not abuse the Power Cord. Do not use the Power Cord to pull its Plug from
an electrical outlet. Keep the Power Cord away from heat, oil, sharp edges, and
moving parts. Route the Power Cord safely. Protect the Power Cord from being
damaged by other equipment in the work area. Do not route the Power Cord
where it can be walked on or tripped over. Replace a damaged Power Cord
immediately.
Do not use this Miter Saw for cutting metals or brittle materials. Do not cut

Before using the Miter Saw, make sure the Saw Blade is properly mounted
on the Saw Spindle. Make sure the Saw Blade is balanced, and is not cracked
or bent.
11.

14.
The Saw Blade will become hot while cutting. Allow the Saw Blade to
completely cool before touching.
Make sure the workpiece is free from nails and any other foreign objects
which can damage the Saw Blade.
Keep your body positioned to either side of the Saw Blade, but not in line
with the Saw Blade. “Kickback” can cause the Saw to jump backwards.
Causes and operator prevention of “kickback”: Kickback is a sudden
reaction to a pinched, bound, or misaligned Saw Blade, causing an uncontrolled
Saw to lift up and out of the workpiece toward the operator. When the Saw Blade
is pinched or bound tightly by the kerf closing down, the Saw Blade stalls and
the Motor reaction drives the tool rapidly toward the operator. If the Saw Blade
becomes twisted or misaligned in the cut, the teeth at the back edge of the Saw
Blade can dig into the top surface of the workpiece, causing the Saw Blade to
climb out of the kerf and jump toward the operator. Kickback is a result of tool
misuse and/or incorrect operating procedures or conditions and can be
minimized by taking proper precautions as given below:
Maintain a rm grip with both hands on the Saw, and position your body
a.
and arm to allow you to resist kickback forces.
When the Saw Blade is binding, or when interrupting a cut for any
b.
reason, release the Power Switch and hold the Saw motionless in the
workpiece until the Saw Blade comes to a complete stop. Never attempt
to remove the Saw Blade from the workpiece or pull the Saw backward while
the Saw Blade is in motion or kickback can occur.
When restarting the Saw in the workpiece, center the Saw Blade in the
c.
kerf and check that the saw teeth are not engaged into the workpiece. If
the Saw Blade is binding, it may walk up or kickback from the workpiece as
the Saw is restarted.
Support large panels to minimize the risk of Saw Blade pinching and
d.
kickback. Large panels tend to sag under their own weight. Supports must
be placed under the panel on both sides, near the line of cut and near the
edge of the panel.
Do not use a dull or damaged Saw Blade. Unsharpened or improperly set
e.
Saw Blades produce a narrow kerf causing excessive friction, Saw Blade
binding and kickback.
Make sure all Saw adjustments are tight and secure before making a cut.
f.
If Saw adjustments shift while cutting, it may cause binding and kickback.

15.
The Cross Pin (28) should always be in the “locked down” position when
the Saw is not being used and when the Saw is being transported. The
Cross Pin should be activated in the “locked up” position when changing
Saw Blades. NEVER use the Cross Pin in any cutting operation. The Cross
Pin allows the operator to lock the Saw Blade in position, preventing the Saw
Blade from being raised or lowered.
16.
17.
18.
19.
20.
21.
Allow the Saw Blade to spin up to full speed before feeding it into the
workpiece. Do not force the Saw Blade into the workpiece when cutting. Apply
moderate pressure, allowing the Saw Blade to cut without being forced. When
turning off the Saw, allow the Saw Blade to spin down and stop on its own. Do
not press against the Saw Blade to stop it.
Turn off the Saw and allow the Saw Blade to stop on its own if the Saw
Blade is to be backed out of an uncompleted cut.
Industrial applications must follow OSHA requirements.
Proper Miter Saw location: Make sure the Miter Saw is located on a at, level,
sturdy surface capable of supporting the weight of the Miter Saw, workpieces,
and all other tools and accessories.
Do not abuse the Power Cord. Do not use the Power Cord to pull the Power
Plug from an electrical outlet. Keep the Power Cord away from heat, oil, sharp
edges, and moving parts. Route the Power Cord safely. Do not route the Power
Cord where it can be walked on or tripped over. Replace a damaged Power Cord
immediately.
Keep all safety guards in place, in proper adjustment, and in proper
alignment.

26.
Never attempt to remove material stuck in the moving parts of the Miter
Saw while the machine is plugged in and running.
Whenever possible, use clamps or other safe, practical ways to hold and
support the workpiece. Do not attempt to cut material that does not have a at
surface, unless a suitable support is used.
Always keep hands and ngers away from the spinning Saw Blade.
Use eye, hearing, and breathing protection. Always wear ANSI-approved
safety impact eye goggles, hearing protectors, and dust masks or respirator
when working with the Miter Saw.
