   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.

 

Stay alert, watch what you are doing, and use 
common sense when operating a power tool. Do 
not use tool while tired or under the influence 
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.

 

Do not overreach. Keep proper footing and balance 
at all times.

 Proper footing and balance enables better 

control of the tool in unexpected situations.

 

Use safety equipment. Always wear eye protection. 

Dust mask, nonskid safety shoes, hard hat, or hearing 
protection must be used for appropriate conditions.

 

Do not use on a ladder or unstable support.

 Stable 

footing on a solid surface enables better control of the 
tool in unexpected situations.

TOOL USE AND CARE

 

Do not exceed the pressure rating of any 
component in the system.

 

Never use this compressor to inflate low pressure 
objects (i.e. toys, footballs, etc.).

 

Protect material lines and air lines from damage or 
puncture.

 Keep hose and power cord away from sharp 

objects, chemical spills, oil, solvents, and wet floors.

 

Check hoses for weak or worn condition before 

GENERAL SAFETY RULES

   WARNING:

Failure to comply with safety precautions and 
procedures outlined in this manual may void your
