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.

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
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.
Use Only Impact Sockets and Accessories
Only use sockets designated “For Use With Impact
Wrenches.” Hand tool sockets can break creating a
hazard from flying pieces. Always check sockets,
retainers and drives regularly for wear or damage and
replace when necessary.
