WARNING
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 INFORMATION BEFORE
OPERATING THIS TOOL.
• It is the responsibility of the owner to make sure all
personnel read this manual prior to using this air tool.
It is also the responsibility of the air tool owner to keep
this manual intact and in a convenient location for all
to see and read. If the manual or product labels are
lost or not legible, contact Cornwell for replacements.
If the operator is not fluent in English, the product and
safety instructions shall be read to and discussed
with the operator in the operator's native language by
the purchaser/owner or his designee, making sure
that the operator comprehends its contents.
• 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 protection when
operating or performing maintenance on this tool
(users and bystanders).
• Always wear hearing protection when using this tool
(users and bystanders). 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.
• Keep tool out of reach of children.
• 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 on page 4.
• Air powered tools can vibrate during 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.
• Note direction of rotation BEFORE operating 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.

CAT4112 / CAT4112G 4 06/12/18
AIR SUPPLY
Tools operate on a wide range of air pressures. It is recommended
that air pressure of these tools measures 90 psig at the tool with
the trigger fully depressed and no load applied to the tool. Higher
pressure (over 90 psig; 6.2 bar) raises performance beyond the
rated capacity of the tool, which will shorten tool life 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 water from air lines
and compressor prior to running tool. Clean the air inlet filter screen
weekly. 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.
Ensure an accessible emergency shut off valve has been installed in
the air supply line and make others aware of its location.
LUBRICATION
Lubricate the air motor daily with high quality air tool oil. If no air
line oiler is used, run 1/2 oz. of oil through the tool. The oil can be
squirted into the tool air inlet or into the hose at the nearest con-
nection to the air supply, then run the tool. A rust inhibitive oil is
acceptable for air tools.
WARNING: After an air tool has been lubricated, oil will discharge
through the exhaust port during the first few seconds of operation.
The exhaust port must be covered with a towel before applying air
pressure to prevent serious injury.
OPERATION
This tool is an impacting tool and not a torque meter. When specific
torque is required, it must be checked with a torque meter after
fitting the fastener with the impact. This impact wrench is rated
at 3/4"SAE bolt size. Rating must be downgraded for spring
U bolts, tie bolts, long cap screws, double depth nuts, badly rusted
conditions and spring fastener, as they absorb much of the impact
power. When possible, clamp or wedge the bolt to prevent spring
back.
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 direction of the tool.
When the valve is out, the tool is in forward or right hand direction.
When the valve is pushed in, the tool is in reverse or left hand
direction.
NOTE: 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.
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 condition absorbs energy and reduces power.
NOTE: During operation, safety goggles must always be worn
to guard against flying debris (users and bystanders).
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, disconnect tool from hose and
take tool to your nearest authorized service center.
