Fit the correct size socket to the anvil of the impact wrench. Hold the
impact wrench with one hand and place the socket onto the nut/bolt
to be tightened or removed. Press the trigger and stop the operation
once the nut/bolt is removed or tightened.
WARNING
: Once a bolt or fastener is seated, impacting for longer
than five (5) seconds will cause excessive wear and possible damage to
the impact mechanism. If it takes longer to tighten or loosen your bolt or
fastener, we recommend the use of a larger sized impact wrench.
Operating
This Impact Wrench is designed to
operate on 90 PSI. Lower pressure
(below 90 PSI) will reduce
performance of the tool. Higher air
pressure (over 90 PSI) raises the
performance of the tool beyond its
rated capacity and could cause
serious damage to the tool and the
user.
This tool features a reverse switch
to change the output torque
direction to tighten (assemble) or
loosen (disassemble) the bolt or
fastener. Control the output torque
direction by pushing the reverse
switch button to the F (Forward) or
R (Reverse) position to change the
direction.
This tool features a high and low
torque switch. Push the torque
switch to the higher (H) or lower (L)
position. In the high position torque
output is 800 ft lbs and in the low
position 150 ft lbs.
tool to air supply and run tool slowly for a few seconds to allow air to
circulate the oil. If tool is used frequently lubricate on daily basis and if
tool starts to slow or lose power. When lubricating, also ensure that
screen is clean.
It is recommended that the air pressure at the tool whilst the tool is
running is 90 p.s.i./6.3 bar. The tool can run at lower and higher
pressures with the maximum permitted working air pressure of 100
p.s.i./7.0 bar. For a lower air pressure the tool will give a lower output for
a given setting of the air regulator set for 90 psi operation and an
increased output for higher pressures. Hence it is possible that changes
in supply pressure can give situations where the fastener is under or
over tightened. For changes in pressure, the regulator position and
application should be reassessed.
It is recommended that joint tightness of the threaded fastener
assembly be checked with suitable measuring equipment.

Tool Maintenance
It shall be the tool owner’s and/or employer’s responsibility to assure
that tools are maintained in a safe operating condition. Tool
maintenance and repair shall be performed by authorised, trained,
competent personnel. Tools shall be disconnected from their
compressed air supply before repairs are attempted. Repairs shall be
consistent with the manufacturer’s recommended procedures. Tool,
hoses and fittings shall be replaced if unsuitable for safe operation. It
shall be the tool owner’s and/or employer’s responsibility to keep
required rating markings and warnings on the tool in legible condition.
Safety 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) 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.
8) Check hose and fittings regularly for wear. Use quick connect
couplings only as recommended. See "Putting into Service". Do not
carry the tool by the hose and ensure that the hand is away from the
on/off valve when carrying.
9) Do not attempt to hold or guide the socket by hand when the tool is
running.
10) Do not exceed maximum recommended air pressure.
11) Use safety equipment as recommended.
12) The tool is not electrically insulated. Do not use where there is a
possibility of coming into contact with live electricity.
13) Preferably shut off the air supply before changing sockets or at least
ensure that the hands are well clear of the operating trigger.
14) Take care against entanglement of moving parts of the tool with
clothing, ties, hair, cleaning rags, etc.
15) 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.
16) Only use extensions, adaptors and universal joints suitable for use
with impact wrenches.
17) If the tool appears to malfunction remove from use immediately
and arrange for service and repair.
