GENERAL SAFETY RULES
WARNING:
Read and understand all instructions. Failure to
follow all instructions listed below may result in electric
shock, fire, and/or serious personal injury.
SAVE THESE INSTRUCTIONS
WORK AREA
Keep your work area clean and well lit. Cluttered
benches and dark areas invite accidents. Floor must
not be slippery from wax or dust.
Do not operate power tools in explosive atmo-
spheres, 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 tools. Distractions can cause you to lose
control.
Operate air compressor in an open area at least 18
in. away from any wall or object that could restrict
the flow of fresh air to ventilation openings.
ELECTRICAL SAFETY
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.
Don’t expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
Do not abuse the cord. Never use the cord to carry
the tool or pull the plug from an outlet. Keep cord
away from heat, oil, sharp edges, or moving parts.
Replace damaged cords immediately. Damaged
cords increase the risk of electric shock.
When operating a power tool outside, use an
outdoor extension cord marked “W-A” or “W”.
These cords are rated for outdoor use and reduce the
risk of electric shock.
PERSONAL SAFETY
Eye protection which conforms to ANSI specifica-
tions and provides protection against flying
particles both from the FRONT and SIDE should
ALWAYS be worn by the operator and others in the
work area when loading, operating, or servicing
this tool. Eye protection is required to guard against
flying fasteners and debris, which could cause severe
eye injury.
The employer and/or user must ensure that proper
eye protection is worn. We recommend a Wide Vision
Safety Mask for use over eyeglasses or standard safety
glasses that provide protection against flying particles
both from the front and side. Always use eye protection
which is marked to comply with ANSI Z87.1.
Additional safety protection will be required in
some environments. For example, the working area
may include exposure to a noise level which can lead to
hearing damage. The employer and user must ensure
that any necessary hearing protection is provided
and used by the operator and others in the work
area. Some environments will require the use of head
protection equipment. When required, the employer
and user must ensure that head protection marked to
comply with ANSI Z89.1 is used.

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
by an authorized service center. Following this rule
will reduce the risk of shock, fire or serious injury.
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. A wire gauge size (A.W.G.) of at
least 14 is recommended for an extension cord 50
feet or less in length. A cord exceeding 100 feet is
not recommended. If in doubt, use the next heavier
gauge. The smaller the gauge number, the heavier
the cord. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating.
