Safety
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.
READ OPERATING INSTRUCTIONS
Always become familiar with all the instructions and warnings before operating any pneumatic tool.
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.

WARNING
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 timeweighted 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
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.
CAUTION
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.

3/4-Inch High Torque Impact Wrench Operator's Manual |
Installation
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.
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.

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. ALWAYS CHECK 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.
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.
