Do not use impact wrench beyond rated capacity as this will drastically reduce tool life.
NOTE: Actual torque on a fastener is directly related to joint hardness, tool speed, condition of socket and the time the tool is
allowed to impact. Use the simplest possible tool-to-socket hook up.
Every connection absorbs energy and reduces power.
Safe Rules When Using an Impact
Wrench
1) Read all the instructions before using this tool. All operators must be fully trained in its use and aware of these safety
rules. All service and repair must be carried out by trained personnel.
2) The socket used must be of the correct drive size and the “impact” type. Never use sockets other than impact type.
3) Do not use sockets with excessive wear to the input and output drives. Check that the square on any other type of drive
or the impact wrench is not cracked or excessively worn before fitting or changing socket, extension, etc. make sure that
the socket is firmly fixed to the tool.
4) Always ensure that a stable position or footing is adopted before using the tool.
5) Ensure that the tool has been correctly set up on a test joint. Incorrect set up could cause joint breakage with sudden
and unexpected movement of the tool.
6) Use only correct spare parts for repair.
7) Check hose and fittings regularly for wear. Use quick connect couplings only as recommended. See “Putting into
Service”. Do not carry the tool by hose and ensure that the hand is away from the on /off valve when carrying.
8) Do not attempt to hold or guide the socket by hand when the tool is running.
9) Do not exceed maximum recommended air pressure.
10) Use safety equipment as recommended.
11) Take care against entanglement of moving parts of the tool with clothing, ties, hair, cleaning rags, etc.
12) Only use extensions, adaptors and universal joints suitable for use with impact wrenches.
13) If the tool appears to malfunction, remove from use immediately and arrange for service and repair.
14) Release the on/off valve in case if a failure of energy supply.
15) Use only the lubricant recommended by the manufacturer.
Warning
1) The tool shall not be used in explosive atmospheres unless specially designed for that purpose.
2) The tool is not electrically insulated. Do not use where there is a possibility of coming into contact with live electricity.
3) Unexpected tool movement due to reaction forces or breakage of inserted tool or reaction bar may cause injuries.
4) Preferably shut off the air supply before changing socket or at least ensure that the hands are well clear of the operating
trigger.
5) Be aware of the risk of crushing by torque between a reaction bar and the workplace.
6) 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 etc. is loosened and rides up the thread moving the tool with
it.
7) There is a risk of being injured specially when unscrewing in confined work place if hands are not kept away from the
reaction bar. Keep hands away from the nut runner socket.
8) In case of nut runner socket failure, it may danger to person from high speed splinters being emitted from impact
wrench.
9) Be aware of the whipping compressed air hose.
10) Always ensure that the reverse valve is in the correct position before operating the tool. Do not run the tool unless the
socket is first located on the joint.
11) Prevent the loose clothes, long hair, or any other personal accessories from closing to the moving part to reduce the risk
of being caught, trapped or drawn in the rotating spindle.
