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. It is recommended that the tool is connected to the air supply as shown
in figure A on page 7 . 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 on page 7 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 air inlet 1 teaspoon (5cc.) 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.
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.
19) Always ensure that the forward/reverse switch is in the desired position before starting the tool.
20) Do not use sockets with excessive wear to the input or output drives. Periodically check the squae
drive on the impact wrench. Make surer the socket, extension bar, or other attachment is securely
fitted before operating tool.
21) When loosening fasteners first ensure that there is sufficient clearance behind the tool to avoid
hand entrapment. The tool will move away from the threaded joint as the nut/bolt is loosened and
rides up the thread, moving the tool with it.
