Read Operating Instructions
Please 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 set forth in ANSI Z87.1, Occupational
and
Educational Eye and Face Protection. Look for marking
Z87.1 on your eye protection to ensure that it is an
approved style.
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 in a given 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. Discontinue the use of any
tool if you experience tingling, numbness, discomfort or
pain in your hands or arms. You should consult your
physician before resuming use of tool.
90 PSI Maximum
This tool is designed to operate at an air pressure of 90
pounds per square inch gauge pressure (90 PSI)
maximum, at the toot. Use of higher air pressure can,
and may cause injury. Also, the use of higher air pressure
places the internal components
under loads and
stresses they were not designed for, causing premature
tool failure.
NOTE: THEAIR SUPPLYSHOULD BE CLEAN, DRYAND
PREFERABLY LUBRICATED. F OR BESTRESULTSDRAINTHE

Use Only Impact Sockets & 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.

WARNING: Some dust created by using power tools
contains chemicals known to the state of California to
cause cancer and birth defects or other reproductive
harm.
Some examples of these chemicals
are:
•
Lead from lead based paint
•
crystalline
silica from bricks and cement
and other masonry products, and
•
arsenic and chromium
from chemically-
treated lumber.
, WARNING]
Your risk from those exposures varies, depending on
how often you do this type of work. To reduce your
exposure to these chemicals: work in a well ventilated
area, and work with approved safety equipment,
such as
dust masks that are specifically designed to filter out
microscopic
particles.

Pre-Operation
Before the tool is connected to the air supply, clear the air
hose of accumulated
dust and moisture by running air
freely through the air hose for 5-10 seconds.
Before
removing a toot for service or changing sockets, make
sure the air line is shut-off at the compressor.
This will
prevent the tool from operating if the throttle is accidentty
engaged.
Installation
(See figure
1)
This toot is designed to operate at 90 psi. Lower pres-
sure (below 90 psi) will reduce performance
of the toot
while higher air pressure (over 90 psi) raises the perfor-
mance of the toot beyond its rated capacity and could
cause serious damage to tool and user.
Always use clean dry air. Excessive moisture and dirt wilt
greatly reduce the life of any air motor. We recommend
the installation of an in-line filter-regulator-lubricator
as
close to the toot as possible.
A 3/8" air hose is required up to a length of 8 ft. If more
length is required a 1/2" air hose should be used at the
compressor.
Attach a 3/8" whip hose for the remaining
4 - 8 ft. for flexibility. Be sure all hoses and fittings are the
correct size and tightly secured before using air tool.
