WARNING
To avoid respiration or inhalation risk: Always wear a face mask or respirator adjusted
correctly when using these tools. Some materials such as adhesives and tar gases contain
chemicals that can cause serious injury due to prolonged exposure.
Always work in a clean, dry and well ventilated area.
To avoid risk of fire or explosion: Never operate pneumatic tools near flammable substances
such as gasoline, naphtha, solvents for cleaning etc. Work in a clean and well ventilated area
free of combustible materials.
To avoid risk of injury never operate the tools under the influence of drugs, alcohol, or when
tired.
To avoid risk of injury do not use excessive force, always allow the tool to perform its work
thoroughly.
To avoid risk of injury: Never use tools that have fallen or have been impacted or damaged by
use. Always check the moving parts for lose or broken pieces that can affect the operation of
the tool. Repair services should only be performed through one of the authorized service
centers.
Read and understand this instruction manual and tool labels before installing, operating or
servicing this tool. Keep these instructions in a safe accessible place.
Operators and others in work area must wear ANSI Z87.1 approved safety glasses with side
shields.
Operators and others in work area must wear ear protection.
Always disconnect from air source when oiling or servicing the tool, or when changing
attachments.
Avoid prolonged use: repetitive motion or exposure to vibration may be harmful to your hands
or arms.
Do Not Use oxygen or reactive gases; explosion may occur.
Do Not Exceed air pressure of 90 PSI (6.2 BAR).
Oil daily for optimal performance.

General Safety Rules for
Pneumatic Tools
WARNING:
1. Read all instructions before using this tool. All operators must
be fully trained in its use and aware of these safety rules.
2. Do not exceed the maximum working air pressure of 90 psi/
6.2 bar.
3. Use personal safety equipment.
4. Use only compressed air at the recommended conditions.
5. If the tool appears to malfunction, remove from use
immediately and arrange for service and repair.
6. If the tool is used with a balancer or other support device,
ensure that it is fixed securely.
7. Always keep hands away from the working attachment fitted
to the tool.
8. The tool is not electrically insulated. Never use the tool if there
is any chance of it coming into contact with live electricity.
9. When using the tool, always adopt a firm footing and/or
position and grip the tool firmly to counteract any forces or
reaction forces that may be generated while using the tool.
10. Use only correct spare parts. Do not improvise or make
temporary repairs.
11. Do not lock, tape, wire, etc. the on/off trigger in the run
position. The trigger must always be free to return to the "off"
position when it is released.
12. Always shut off the air supply to the tool and depress the
trigger to release air from the feed hose before fitting, adjusting
or removing the working attachment.
13. Check hoses and fittings regularly for wear.Replace if
necessary. Do not carry the tool by its hose. Ensure the hand is
removed from the on/off trigger when carrying the tool with
the air supply connected.
14. Take care against entanglement of moving tool parts with
clothing, ties, hair, cleaning rags, etc. This will cause the body
to be drawn towards the tool and can be very dangerous.
15. It is expected that users will adopt safe working practices and
observe all relevant legal requirements when installing, using or
maintaining the tool.
16. Only install the tool when an easily accessible and easily
operable on/off switch is incorporated in the air supply.
17. Take care that the tool exhaust air does not cause problems or
blow onto another person.
18. Never lay a tool down unless the working attachment has
stopped moving.
Proper Use Of The Tool
Your new 1/2" drive impact wrench is designed for driving,
tightening and loosening threaded fasteners, usually nuts and bolts,
when fitted with a suitable impact socket. Always use impact-rated
extension bars, universal joints and socket adapters between the
square output drive of the impact wrench and the female square
drive of the socket. Do not use the tool for any other purpose than
that specified without consulting the manufacturer or the
manufacturer's authorized supplier. To do so may be dangerous.
Never use the impact wrench as a hammer to dislodge or
straighten cross threaded fasteners. Never attempt to modify the
tool for other uses.
Work Stations
Your impact wrench should only be used as a hand operated tool.
It is always recommended that the tool is used when standing
with solid footing. It can be used in other positions but before any
such use, the operator must be in a secure position having a firm
grip and footing and be aware that when loosening fasteners the
tool can move quite quickly away from the fastener being undone.
An allowance must always be made for this rearward movement
so as to avoid the possibility of hand/arm/body entrapment.

Putting Into Service

Air Supply
Use a clean lubricated air supply that will give a measured air
pressure at the tool of 90 psi/6.2 bar when the tool is running with
the trigger fully depressed. Use recommended hose size and
length. It is recommended that the tool is connected to the air
supply as shown in Figure A. Do not connect the tool to the air line
system without incorporating an easy to reach and operate air shut
off valve. The air supply should be lubricated. It is strongly
recommended that an air filter, regulator, lubricator (FRL) is used as
shown in Figure A as this will supply clean, lubricated air at the
correct pressure to the tool. Details of such equipment can be
obtained from your supplier. If such equipment is not used then the
tool should be lubricated by shutting off the air supply to the tool
and then depressurizing the line by pressing the trigger on the tool.
Disconnect the air line and pour into the intake bushing a teaspoon
(5 ml) of a suitable pneumatic motor lubricating oil, preferably
incorporating a rust inhibitor. Reconnect tool to air supply and
run tool slowly for a few seconds to allow air to circulate the oil.
Lubricate tool daily if used frequently, or when it starts to slow or
lose power.
