EXPOSURE TO
VIBRATION
Some dust created by power sanding, sawing, grinding, drilling,
and other construction activities contains chemicals known to
cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement
and other masonry products, and
• 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 ventilated area, and work with
approved safety equipment, such as those dust masks that are
specially designed to filter out microscopic particles.

THIS INSTRUCTION MANUAL CONTAINS
IMPORTANT SAFETY INFORMATION.
READ THIS INSTRUCTION MANUAL
CAREFULLY AND UNDERSTAND ALL
INFORMATION BEFORE OPERATING
THIS TOOL.
• Always operate, inspect and maintain this
tool in accordance with American National
Standards Institute Safety Code of Portable
Air Tools (ANSI B186.1) and any other
applicable safety codes and regulations.
• For safety, top performance and maximum
durability of parts, operate this tool at 90
psig 6.2 bar max air pressure with 3/8"
diameter air supply hose.
• Always wear impact-resistant eye and face
protection when operating or performing
maintenance on this tool. Always wear
hearing protection when using this tool.
• High sound levels can cause permanent
hearing loss. Use hearing protection as
recommended by your employer or OSHA
regulation.
• Keep the tool in efficient operating condition.
• Operators and maintenance personnel must
be physically able to handle the bulk,
weight and power of this tool.
• Air under pressure can cause severe injury.
Never direct air at yourself or others.
Always turn off the air supply, drain hose of
air pressure and detach tool from air supply
before installing, removing or adjusting any
accessory on this tool, or before performing any
maintenance on this tool. Failure to do so
could result in injury. Whip hoses can cause
serious injury. Always check for damaged,
frayed or loose hoses and fittings, and
replace immediately. Do not use quick
detach couplings at tool. See instructions for
correct set-up.
• Air powered tools can vibrate in use.
Vibration, repetitive motions or
uncomfortable positions over extended
periods of time may be harmful to your
hands and arms. Discontinue use of tool if
discomfort, tingling feeling or pain occurs.
Seek medical advice before resuming use.
• Place the tool on the work before starting
the tool.
• Slipping, tripping and/or falling while
operating air tools can be a major cause of
serious injury or death. Be aware of excess
hose left on the walking or work surface.
• Keep body working stance balanced and
firm. Do not overreach when operating the tool.
• Anticipate and be alert for sudden changes
in motion during start up and operation of
any power tool.
• Do not carry tool by the hose. Protect the
hose from sharp objects and heat.
• Tool shaft may continue to rotate briefly
after throttle is released. Avoid direct
contact with accessories during and after
use. Gloves will reduce the risk of cuts or burns.
• Keep away from rotating end of tool. Do
not wear jewelry or loose clothing. Secure
long hair. Scalping can occur if hair is not
kept away from tool and accessories.
Choking can occur if neckwear is not kept
away from tool and accessories.
• Impact wrenches are not torque control
devices. Fasteners with specific torque
requirements must be checked with suitable
torque measuring devices after installation
with an impact wrench.
• Use only impact wrench sockets and
accessories on this tool. Do not use hand
sockets and accessories.
• Do not lubricate tools with flammable or
volatile liquids such as kerosene, diesel or
jet fuel.
• Don’t force tool beyond its rated capacity.
• Do not remove any labels. Replace any
damaged labels.
FAILURE TO OBSERVE THESE WARNINGS COULD RESULT IN INJURY.

Air Supply...
Tools of this class operate on a wide range of air pressures. It is
recommended that air pressure of these tools measure 90 PSI at
the tool while running free. Higher pressure (over 90 psig; 6.2
bar) raises performance beyond the rated capacity of the tool
which will shorten the tool’s life because of faster wear and could
cause injury.
Always use clean, dry air. Dust, corrosive fumes and/or water in
the air line will cause damage to the tool. Drain the air tank
daily. Clean the air inlet filter screen on at least a weekly
schedule. The recommended hookup procedure can be viewed in
the above figure.
The air inlet used for connecting air supply, has standard 1/4"
NPT. Line pressure should be increased to compensate for
unusually long air hoses (over 25 feet). Minimum hose diameter
should be 3/8" I.D. and fittings should have the same inside
dimensions and be tightly secured.
Lubrication...
Lubricate the air motor daily with quality air tool oil. If no air line
oiler is used, run a teaspoon of oil through the tool. The oil can
be squirted into the tool air inlet or into the hose at the nearest
connection to the air supply, then run the tool. The amount of oil
to be used is 1 ounce. Overfilling will cause a reduction in the
power of the tool.
Operation...
The air regulator knob can be used as an air throttle, if there are
no other means of regulating air. Turn the air regulator knob all
the way to position 4 for maximum power.
The air regulator can be used to adjust torque to the
approximate tightness of a known fastener.To set the tool to
desired torque, select a nut or screw of known tightness of the
same size, thread pitch and thread condition as those on the job.
Turn air regulator to low position, apply wrench to nut and
gradually increase power (turn regulator to admit more air) until
nut moves slightly in the direction it was originally set. The tool is
now set to duplicate that tightness - note regulator setting for
future use. When tightening nuts not requiring critical torque
values, run nut up flush and then tighten an additional one-
quarter to one-half turn (slight additional turning is necessary if
gaskets are being clamped). For additional power needed on
disassembly work, turn regulator to its fully open position. This
impact wrench is rated at 3/8" USS bolt size. Rating must be
down graded for spring U bolts, tie bolts, long cap screws,
double depth nuts, badly rusted conditions and spring fasteners
as they absorb much of the impact power. When possible, clamp
or wedge the bolt to prevent springback.
Soak rusted nuts in penetrating oil and break rust seal before
removing with impact wrench. If nut does not start to move in
three to five seconds use a larger size impact wrench. Do not use
impact wrench beyond rated capacity as this will drastically
reduce tool life.
The reversing valve is used to change the rotation of the tool.
When the valve is out, the tool is in a forward or right hand
rotation. When the valve is pushed in, the rotation is reverse or
left hand.
NOTE: Actual torque on a fastener is directly related to joint
hardness, tool speed, condition of socket and the time the tool is
allowed to impact.
Use the simplest possible tool-to-socket hook up. Every
connection absorbs energy and reduces power.
