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.

Safety

3/4-Inch Heavy Duty Impact Wrench Operator's Manual 5

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 Heavy Duty 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 Heavy Duty Impact Wrench Operator's Manual 7

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 Heavy Duty 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 John Deere AT-4003 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 1½ oz. (45ml) of John

Deere AT-4003 oil. Never over fill the anvil mechanism. 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 of tool 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:

Impact wrench has a built-in power regulator, which can be adjusted by turning the

valve counter-clockwise to increase and clockwise to decrease. The numbers on the

dial are only for reference and do not denote a specific power output.

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

RATCHET IN TIGHT AREAS. HANDS AND FINGERS

SHOULD NOT BE HELD BETWEEN TOOL AND

WORK SURFACE. PERSONAL INJURY MAY

RESULT.

Troubleshooting

Specifications

Loss of Power

1. Low air pressure

2. Improper lubrication or dirt

build up

3. Worn motor parts, or other

problems

1. Check air supply. For

rated performance, 90

PSI air pressure is

required at the tool, with

tool operating

2. Check for wet or dirty air.

Wet air tends to wash

lubricant away. Dirt or

foreign matter will

impede the action of the

motor. If dirt or water has

entered the tool, flush

with John Deere AT-

4003.

3. Contact your customer

service.
