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.

FAILURE TO OBSERVE THESE WARNINGS COULD RESULT IN INJURY.
This Instruction Manual Contains Important Safety
Information.
Read THIS INSTRUCTION MANUAL
Carefully and understand ALL INFORMA-
TION 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. Do
not point or indulge in any horseplay with this 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

Operating Instructions • Warning Information • Parts Breakdown
Air Supply
Tools of this class operate on a wide range
of air pressures. It is recommended that air
pressure of these tools measures 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 tool 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 recom-
mended 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.
Operation
This ratchet 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 ratchet
wrench. If nut does not start to move in
three to five seconds use an impact wrench.
Do not use impact wrench beyond rated
capacity as this will drastically reduce tool
life.
The forward/reversing button is used to
change the rotation of the tool. When the
button is set to the right, the tool will turn
in a right hand rotation. When the button
is set to the left, the tool will turn in a left
hand rotation.
NOTE: Actual torque on a fastener is direct-
ly 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.
Troubleshooting
Other factors outside the tool may cause
loss of power or erratic action. Reduced
compressor output, excessive drain on the
air line, moisture or restrictions in air pipes
or the use of hose connections of improper
size or poor conditions may reduce air
supply. Grit or gum deposits in the tool
may cut power and may be corrected by
cleaning the air strainer and flushing out
the tool with gum solvent oil or an equal
mixture of SAE #10 and kerosene. If
outside conditions are in order and the tool
continues to perform erratically, disconnect
tool from hose and take tool to your nearest
authorized service center.
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.
Grease ratchet yoke as needed.
