cause accidents.

• Do not use your Impact Wrench where there is a risk of causing a ﬁre or an

explosion; e.g. in the presence of ﬂammable liquids, gasses, or dust. An Impact

Wrench can create sparks, which may ignite the dust or fumes.

• Keep children and bystanders away while operating the Impact Wrench. Distractions

can cause you to lose control, so visitors should remain at a safe distance from the

work area.

• Be aware of all power lines, electrical circuits, water pipes and other mechanical

hazards in your work area, particularly those hazards below the work surface hidden

from the operator’s view that may be unintentionally contacted and may cause

personal harm or property damage.

• Be alert of your surroundings. Using the Impact Wrench in conﬁned work areas may

put you dangerously close to cutting tools and rotating parts.

WORK AREA

SAVE THESE INSTRUCTIONS

PERSONAL SAFETY

• Stay alert, watch what you are doing and use common sense when operating the

Impact Wrench. Do not use the Impact Wrench while you are tired or under the

inﬂuence of drugs, alcohol or medication. A moment of inattention while operating the

Impact Wrench may result in serious personal injury.

• Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your

hair, clothing and gloves away from moving parts. Loose clothes, jewelry or long hair

can be caught in moving parts. Air vents often cover moving parts and should be

avoided.

• Use safety apparel and equipment. Use safety goggles or safety glasses with side

shields which comply with current national standards, or when needed, a face shield.

Use a dust mask in dusty work conditions. This applies to all persons in the work area.

Also use non-skid safety shoes, hardhat, gloves, dust collection systems, and hearing

protection when appropriate.

• Do not overreach. Keep proper footing and balance at all times.

• Remove sockets or wrenches before connecting to the power supply or turning on the

tool. A wrench or socket that is left attached to a rotating part of the tool may result in

personal injury.

• Do not force the tool. Pneumatic tools do a better and safer job when used in the

manner for which they are designed. Plan your work, and use the correct tool for the

job.

• Never use a tool with a malfunctioning throttle switch. Any power tool that cannot be

controlled with the throttle switch is dangerous and must be repaired by an authorized

service representative before using.

• Disconnect air supply from tool and place the throttle switch in the locked or “off”

position before making any adjustments, changing accessories, or storing power

tools. Such preventive safety measures reduce the risk of starting the power tool

accidentally.

• Secure work with clamps or a vise instead of your hand to hold work when practical.

This safety precaution allows for proper tool operation using both hands.

• Store idle tools. When tools are not is use, store them in a dry, secure place out of the

reach of children. Inspect tools for good working condition prior to storage and before

re-use.

• Use only impact sockets and accessories that are recommended by the manufacturer

for your model. Impact sockets and accessories that may be suitable for one tool may

create a risk of injury when used on another tool. Never use chrome hand tool

sockets as they may break and cause personal injury.

• Keep guards in place and in working order.

• Never leave tool running unattended.

• USE COMPRESSED AIR ONLY. Use clean, dry and regulated compressed air to power

this tool. Never use oxygen, carbon dioxide or any other bottled gas as a power

source for this tool.

PNEUMATIC TOOL USE AND CARE

WARNING: Ensure the air supply is clean and does not exceed 90 PSI. while operating the

tool. Too much air pressure and unclean air will shorten the product life due to excessive

wear, and may cause damage and/or personal injury.

1. Make sure that the air valve (or trigger) is in the “off” position before connecting to

the air supply.

2. An air pressure of 90 PSI. is required.

3. Drain the air tank daily. Water in the airline can damage the tool.

4. Clean the air inlet ﬁlter weekly.

5. Line pressure should be increased to compensate for longer air hoses (over 26 feet or

8 meters). The hose diameter should be 3/8" I.D.

6. Keep the hose away from heat, oil and sharp edges. Check the hose for wear and

make certain that all connections are secure.

TOOL SET UP

AIR SUPPLY

Air Supply Requirements

Tool is designed to operate at 90 psi (6.2 bar) at free speed measured at the tool, of

clean, dry air. Operating this tool at higher pressures will drastically reduce the tool life

and could cause injury.

The air inlet thread on this tool is a standard 1/4” NPT. Line pressure should be

increased for any unusually long air hose run (over 25 feet). Minimum hose diameter

should be 3/8” I.D. and all ﬁttings should have the same inside diameter. See diagram

below for proper air supply setup.

Lubrication

Lubricate the tool each day after use with quality SAE #10 air motor oil. Add the oil to

the air inlet or into the hose at the nearest connection to the air supply, then run the

tool until all excess oil is expelled from the exhaust. Total oil quantity needed for this

procedure is approximately 1 ounce.

WARNING: Make sure the Impact Wrench is disconnected from its power source before

attempting any maintenance, cleaning, or inspection.

MAINTENANCE

tool be examined before it is used. Keep your Impact Wrench in good repair by

adopting a program of conscientious repair and maintenance in accordance with

the recommended procedures found in this manual. If any abnormal vibrations or

noise occurs, turn the Impact Wrench off immediately and have the problem corrected

before further use. Have necessary repairs made by qualiﬁed service personnel.

• Keep handles dry, clean, and free from oil and grease.

• Cleaning. Use only soap and a damp cloth to clean your Impact Wrench. Many
