READ OPERATING INSTRUCTIONS
Always become familiar with all the instructions and
warnings before operating any pneumatic tool.
RECOGNIZE SAFETY INFORMATION
This is the safety alert symbol. When you see this symbol on
your pneumatic tool or in this manual, be alert to the potential
for personal injury.
Follow recommended precautions and safe operating
practices.
UNDERSTAND SIGNAL WORDS
A "DANGER, WARNING or CAUTION" safety warning will be
surrounded by a "SAFETY ALERT BOX." This box is used to
designate and emphasize Safety Warnings that must be
followed when operating this tool.
Accompanying the Safety Warnings are "signal words" which
designate the degree or level of hazard seriousness. The
"signal words" used in this manual are as follows:
DANGER: Indicates an imminently hazardous situation
which, if not avoided, WILL result in death or
serious injury.
WARNING: Indicates a potentially hazardous situation
which, if not avoided, COULD result in death or
serious injury.
CAUTION: Indicates a potentially hazardous situation
which, if not avoided MAY result in minor or
moderate injury.
ALWAYS PROVIDE A COPY OF THIS MANUAL TO
ANYONE USING THIS EQUIPMENT. READ ALL
INSTRUCTIONS BEFORE OPERATING THIS TOOL
AND ESPECIALLY POINT OUT THE "SAFETY
WARNINGS" TO PREVENT THE POSSIBILITY OF
PERSONAL INJURY TO THE OPERATOR.

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 85 dBA. 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.
WEAR RESPIRATORY PROTECTION
It is advisable, when using this tool for extended
periods of time, to wear a protective mask. This will
help prevent the inhalation of the fine dust produced
while using this tool. Prolonged breathing of dust
particles may lead to future respiratory problems.
Some dust created by power sanding, sawing,
grinding, drilling and other construction activities
contain chemicals known to cause cancer, birth
defects or reproductive harm. Some examples of
these chemicals are:
• Lead from lead-base paints
• Crystalline Silica from bricks, cement and other
masonry products.
• 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.
WARNING
6 3/4-Inch High Torque Impact Wrench Operator's Manual
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
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.
NOTE: 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.
WARNING
CAUTION
3/4-Inch High Torque Impact Wrench Operator's Manual

Always use clean dry air. Excessive moisture and dirt will greatly reduce the life of any
air motor. We recommend the installation of an in-line filter-regulator-lubricator as
close to the tool 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 connected to the 3/8" hose to ensure the tool has the necessary air
supply. Be sure all hoses and fittings are the correct size and tightly secured.
Designed to operate on 90 PSIG, lower pressure (below
90 PSIG) will reduce performance of the tool while higher air
pressure (over 90 PSIG) raises the performance of the tool
beyond its rated capacity and could cause serious damage to
tool and user.

RECOMMENDED AIR LINE SET-UP
8 3/4-Inch High Torque Impact Wrench Operator's Manual
Maintenance
LUBRICATION:
An automatic in-line filter-regulator-lubricator is recommended as it increases tool life
and keeps the tool in sustained operation. The in-line lubricator should be regularly
checked and filled with air tool oil. Proper adjustment of the in-line lubricator is
performed by placing a sheet of paper next to the exhaust ports and holding the throttle
open approximately 30 seconds. The lubricator is properly set when a light stain of oil
collects on the paper. Excessive amounts of oil should be avoided.
The oil reservoir in the anvil housing should be checked every 40 hours of operation.
Remove the oil plug from the housing and hold tool so the oil port is lower than the
anvil housing. Drain oil. Measure and refill with approximately 1 oz. (30 ml) of John
Deere AT-4003 oil. Never overfill the anvil mechanism or excessive pressure will be
created reducing tool speed and power. If the tool becomes sluggish after adding oil,
remove a small amount of oil and check performance again.
In the event that it becomes necessary to store the tool for an extended period of time
(overnight, weekend, etc.), it should receive a generous amount of lubrication at that
time. The tool should be run for approximately 30 seconds to ensure oil has been
evenly distributed throughout the tool. The tool should be stored in a clean and dry
environment.
Recommended lubricants: Use John Deere AT-4003 air tool oil or any other high
grade turbine oil containing moisture absorbent, rust inhibitors, metal wetting agents
and an EP (extreme pressure) additive.
Operation
PRE-OPERATION:
Before the tool is connected to the air supply, clear the air hose of accumulated dust
and moisture. Before removing a tool for service or changing sockets, make sure the
air line is shut-off and drained of air. This will prevent the tool from operating if the
throttle is accidentally engaged.
OPERATION:
This tool features a built-in-oiler to provide lubrication to the air motor. The fill plug is
located on the housing near the handle and is marked for easy identification. Remove
plug and fill with recommended air tool oil. Oil will be inducted into motor during
regular use and help prevent excessive wear and moisture build-up inside tool.
Once a bolt or fastener is seated, impacting for longer than five seconds will cause
excessive wear and damage to the impacting mechanism. If it takes longer than five
seconds to tighten your bolt or fastener, we recommend the use of a larger size
impact wrench.
CAUTION: ONLY USE SOCKETS DESIGNED FOR IMPACT
TOOLS. USING HAND TOOL SOCKETS CAN BE
HAZARDOUS AND MAY RESULT IN PERSONAL
INJURY. ALWAYSCHECK ACCESSORIES FOR
WEAR, CRACKS AND OTHER DEFECTS BEFORE
USE.
THE DESIGN OF THIS TOOL REQUIRES THAT
EXTRA CARE MUST BE TAKEN WHEN USING THE
WRENCH IN TIGHT AREAS. HANDS AND FINGERS
SHOULD NOT BE HELD BETWEEN TOOL AND
WORK SURFACE. PERSONAL INJURY MAY
RESULT.
