Read Operating Instructions
Always become familiar with all the instructions and
warnings before operating any pneumatic tool.
Always Wear Approved Eye Protection Impact
resistant eye protection should meet or exceed the
standards as set forth in the United States ANSI Z87.1,
Occupational and Educational Eye and Face Protection.
Look for the marking Z87.1 on your eye protection to
insure that it is an approved style. For further
information, ANSI Z87.1, Occupational and Educational
Eye and Face Protection, is available from the American
National Standards Institute, Inc., 11 West 42nd Street,
New York, NY 10036.
Hearing Protection is Recommended
Hearing protection should be used when the noise level
exposure equals or exceeds an 8 hour time-weighted
average sound level of 85dBA. Process noise, reflective
surfaces, other tools being operated nearby, all add to
the noise level present in your work area. If you are
unable to determine your noise level exposure, we
recommend the use of hearing protection.
WARNING: SOME DUST CREATED BY POWER SANDING,
SAWING, GRINDING, DRILLING, AND OTHER CONSTRUCTION
ACTIVITIES CONTAINS CHEMICALS KNOWN TO CAUSE
CANCER, BIRTH DEFECTS OR REPRODUCTIVE HARM. SOME
EXAMPLES OF THESE CHEMICALS ARE:
Avoid Prolonged Exposure to Vibration
Pneumatic tools can vibrate during use. Prolonged
exposure to vibration or very repetitive hand and arm
movements, can cause injury. Stop using any tool if
discomfort, tingling feeling or pain occurs. You should
consult your physician before resuming use of the tool.

90 PSIG Maximum
90 psig
6.2bar/620kPa
Husky impact wrenches are designed to operate at an air
pressure of 90 pounds per square inch gauge pressure
(90 PSIG) maximum, at the tool. Use of higher air pressure
can, and may cause injury. Also use of higher air pressure
places the internal components under loads and stresses
they were not designed for, causing premature tool failure.
The air supply should be clean and dry, preferably
lubricated. For best results drain the moisture from your
compressor daily.
LEAD FROM LEAD-BASED PAINTS
CRYSTALLINE SILICA FROM BRICKS, CEMENT AND OTHER
MASONRY PRODUCTS
ARSENIC AND CHROMIUM FROM CHEMICALLY TREATED
LUMBER
YOUR RISK FROM THESE EXPOSURES VARIES, DEPENDING ON
HOW OFTEN YOU DO THIS TYPE OF WORK. TO REDUCE YOUR
EXPOSURE TO THESE CHEMICALS, WORK IN A WELL VENTI-
LATED AREA AND WORK WITH APPROVED SAFETY EQUIPMENT
SUCH AS THOSE DUST MASKS THAT ARE SPECIALLY DE-
SIGNED TO FILTER OUT MICROSCOPIC PARTICLES.
