SAFETY INSTRUCTIONS….cont
DO NOT dismantle or tamper with the impact wrench, as this may be dangerous and
will invalidate the warranty.
If a problem with the impact wrench is experienced or suspected stop using the im-
pact wrench immediately and contact your distributor for repair.
Regularly inspect and lubricate the impact wrench, ensuring that it is in good working
order and condition.
Always ensure that the work area is clean and tidy, free from unrelated materials and
has adequate lighting.
Clean and stow the impact wrench correctly.
Failure to follow the warnings in this manual, may result in personal injury and/or prop-
erty damage.
DO ensure that only compressed air is used to supply the air tool.
The compressed air supply MUST be at a suitable regulated pressure. Pipe work, reg-
ulators, hoses, isolation valves and connection devices MUST be suitable for the in-
tended application correctly installed and maintained in good condition by a com-
petent person.
Appropriate Personal protective equipment MUST be worn and MUST be designed to
protect against all hazards created. Severe permanent injury can result from using
inappropriate or insufficient protective equipment - Eyes in particular are at risk.
Long hair MUST be tied back; loose clothing MUST NOT be worn. There is a severe risk
of these being drawn in or trapped by the moving parts of the air tool.
Open or damaged compressed air lines present a significant ‘whip’ hazard; isolate
the problem hose from the air supply and repair / replace the hose immediately.
This air tool is electrically conductive DO NOT allow them to come into contact with
any source of electrical supply.
After use wait for the air tool to STOP completely before putting it aside.
When putting the air tool aside you MUST ensure that it placed in a stable position. To
avoid inadvertent operation DO NOT place the air tool where it can be knocked or
moved accidentally either directly or by the air connection hose.
If the air tool is not required or the air supply is interrupted, disconnect the air tool
from the air supply and place in secure storage to prevent unauthorised use.
Ensure the air valve (or trigger) is in the “off” position before connecting to the air sup-
ply.
Disconnect the impact wrench from the air supply before making adjustments,
changing impact wrench bits etc. and before servicing the tool.
Always keep your air tool clean and lubricated. Daily lubrication is essential to avoid
internal corrosion and possible failure.
Do not overload the tool. Allow the tool to operate at its optimum speed for maxi-
mum efficiency.
Do not increase the air pressure above the manufacturers recommended level, as
excessive pressure can cause the tool casing to split. This can also create excessive
wear on moving parts and possible failure.

CAUTION: The warnings and cautions mentioned in this user manual can not
cover all possible conditions and situations that may occur. It must be under-
stood by the operator that common sense and caution are factors which can-
not be built into this product, but must be applied.
We recommend wearing ear protection - particularly during extended
periods of operation.
We recommend wearing a face mask or respiratory equipment when
using any air tool; particularly during drilling, sanding, grinding, sawing or
other operations likely to cause airborne particles.
Always wear approved safety goggles / glasses when using or maintain-
ing any air tool, everyday eyeglasses have only impact resistant lenses,
they are not safety glasses.
SAFETY INSTRUCTIONS….cont
Always ensure that the work-piece is firmly secured leaving both hands free to control
the impact wrench.
Always wear safety goggles or glasses during operation.
Do not wear watches, rings bracelets or loose clothing when using air tools.
Use as light weight a hose as possible from the tool to the wall or compressor cou-
pling.
In the interests of safety and possible damage to the machine/operator, always en-
sure that the impact wrench has stopped before putting it down after use.
Always ensure that the accessories such as impact wrench bits are rated / designed
for use with this impact wrench as well as the required application, and are correctly
and securely fastened before connecting the tool to the air supply.
Do not carry or move the air impact wrench by its air hose.
Never allow the tool to come into contact with harsh solvents such as petrol.
11
DO NOT use the tool if it is, or has parts that are worn, damaged or missing; re-
move from service and have the parts repaired / replaced using original spare
parts.
Ensure that the air tool is lubricated daily with a few drops of air tool oil dripped
into the air inlet.
Clean the air tool after each use.
Check hose and fittings for wear or damage before each use.
Drain the air tank / receiver of the compressor daily; Water in the air line will
damage the impact wrench.
In the event that it becomes necessary to store the tool for an extended period
of time (overnight, weekend, etc.), it should receive a generous amount of lubri-
cation at that time. The tool should be run for approximately 30 seconds to en-
sure oil has been evenly distributed throughout the tool.
The tool should be stored in a clean and dry environment.
Disconnect the air tool from the air supply before changing accessories, servicing
or performing maintenance. Replace or repair damaged parts. Use genuine parts
only. Non-authorised parts may be dangerous and will invalidate the warranty.
MAINTENANCE

10
CAUTION: If a filter/regulator/lubricator is not installed on the air system,
air operated tools should be lubricated at least once a day or after 2
hours work with 2 to 6 drops of oil, depending on the work environment,
directly through the male fitting in the tool housing.
LUBRICATION
An automatic in-line filter-regulator-lubricator is recommended (Fig.1) as it in-
creases tool life and keeps the tool in sustained operation. The in-line lubricator
should be regularly checked and filled with air tool oil.
Proper adjustment of the in-line lubricator is performed by placing a sheet of
paper next to the exhaust ports and holding the throttle open approximately 30
seconds. The lubricator is properly set when a light stain of oil collects on the
paper. Excessive amounts of oil should be avoided.
In the event that it becomes necessary to store the tool for an extended period
of time (overnight, weekend, etc.), it should receive a generous amount of lubri-
cation at that time. The tool should be run for approximately 30 seconds to en-
sure oil has been evenly distributed throughout the tool. The tool should be
stored in a clean and dry environment.
It is most important that the tool be properly lubricated by keeping the air line
lubricator filled and correctly adjusted. Without proper lubrication the tool will not
work properly and parts will wear prematurely.
Use the proper lubricant in the air line lubricator. The lubricator should be of low
air flow or changing air flow type, and should be kept filled to the correct level.
Use only recommended lubricants, specially made for pneumatic applications.
Substitutes may harm the rubber compounds in the tools O-rings and other rub-
ber parts.
The rocking dog mechanism at the front of the wrench should be oiled monthly,
or sooner if the wrench is used heavily; Remove the oil filler bung (6) and pour a
few drops of airtool oil into it. Replace the bung and run the wrench for a short
period to ensure that the oil is distributed around the mechanism.
