BEFORE USE
AIR SUPPLY
• Use only clean, dry, regulated compressed air as a power source for
the impact wrench.
• Air compressors used with the impact wrench must comply with the
appropriate European Community safety directives.
• A build up of moisture or oil in the air compressor will accelerate
wear and corrosion in the impact wrench.
• Never exceed the maximum operating pressure for the impact
wrench.
AIR HOSE
• The air hose must be rated at least 150% of the maximum operating
pressure of the tool.
RECOMMENDED AIR SUPPLY CONNECTION
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF
COMPRESSORS AND COMPRESSED AIR SUPPLY.

BEFORE USE
NOTE: Ensure the compressor is turned off.
1. Remove the travel plug from the
1/4” BSP (Female Air Inlet) as
shown.
2. Fit the inline mini oiler.
• A mini oiler helps to prolong the
life of the impact wrench.
Remove the oil fill screw from
the side of the mini oiler and fill
with Air Line Oil available from
your CLARKE dealer. Replace
the screw before using the
impact wrench.
3. Connect a suitable hose as shown.
• Use the adapter supplied if
required.
4. Connect the other end of the hose
to the compressor.
5. Your impact wrench is now ready
for use.
You can fit a whip hose with a quick fit
coupling if required (available from
your Clarke dealer.)

wrench.
3. Release the trigger switch to stop
the wrench.
• The anvil will continue to rotate
briefly after the trigger has been
released.
DISCONNECTING THE AIR SUPPLY
Do not disconnect the air supply hose until the compressor has been shut
down and the compressed air released.
1. Refer to the compressor instruction manual for the procedure to shut down
and release the compressed air.
2. Once the pressure has been released, disconnect the air supply hose from
the impact wrench.
3. Store the impact wrench safely in its box in a dry, secure environment.

MAINTENANCE
DAILY
• Drain water from the air tank, air line and compressor.
• Pour a few drops of CLARKE air line oil, into the air inlet. This should be
carried out regardless of whether or not the inline mini oiler is used. If
the inline mini oiler is not used, this procedure should be repeated
after every two to three hours of use.
WEEKLY
• Check the air inlet screen filter and clean if necessary.
• Remove the grub screw and
insert a few drops of oil into the
oil port on the side of the
impact wrench.
CLEANING
• Keep the body of the impact
wrench clean and free from
debris. Grit or gum deposits in
the tool may reduce efficiency.
SERVICE AND REPAIR
• All servicing and repair must be carried out by qualified service
technicians.
NOTES
• Please note that factors other than the tool may effect its operation
and efficiency such as reduced compressor output, excessive drain
on the airline, moisture or restrictions in the line, or the use of
connectors of improper size or poor condition which will reduce air
supply.
• **Clarke Air Line Oil (part no. 3050825) is available from your CLARKE
dealer .
WARNING: MAKE SURE THAT THE IMPACT WRENCH IS DISCONNECTED
FROM THE AIR SUPPLY BEFORE STARTING ANY CLEANING, OR
MAINTENANCE PROCEDURES.

STORAGE
• If the tool is to be stored, or is idle for longer than 24 hours, run a few
drops of Clarke air line oil into the air inlet, and run the tool for 5
seconds in order to lubricate the internal parts.
• When not in use, disconnect from air supply, clean tool and store in
a safe, dry place.

VIBRATION EMISSIONS
Employers are advised to refer to the HSE publication “Guide for Employers”.
All hand held power tools vibrate to some extent, and this vibration is
transmitted to the operator via the handle, or hand used to steady the tool.
Vibration from about 2 to 1500 hertz is potentially damaging and is most
hazardous in the range from about 5 to 20 hertz.
Operators who are regularly exposed to vibration may suffer from Hand Arm
Vibration Syndrome (HAVS), which includes ‘dead hand’, ‘dead finger’, and
‘white finger’. These are painful conditions and are widespread in industries
where vibrating tools are used.
The health risk depends upon the vibration level and the length of time of
exposure to it……in effect, a daily vibration dose.
Tools are tested using specialised equipment, to approximate the vibration
level generated under normal, acceptable operating conditions for the tool in
question. For example, a grinder used at 45° on mild steel plate, or a sander on
soft wood in a horizontal plane etc.
These tests produce a value ‘a’, expressed in metres per second per second,
which represents the average vibration level of all tests taken, in three axes
where necessary, and a second figure ‘K’, which represents the uncertainty
factor, i.e. a value in excess of ‘a’, to which the tool could vibrate under
normal conditions. These values appear in the specification panel below.
You will note that a third value is given in the specification - the highest
measured reading in a single plane. This is the maximum level of vibration
measured during testing in one of the axes, and this should also be taken into
account when making a risk assessment.
‘a’ values in excess of 2.5 m/s2are considered hazardous when used for
prolonged periods. A tool with a vibration value of 2.8 m/s2may be used for up
to 8 hours (cumulative) per day, whereas a tool with a value of 11.2 m/s2may
be used for ½ hour per day only.

The graph on the right shows the
vibration value against the maximum
time the respective tool may be
used, per day.
The uncertainty factor should also be
taken into account when assessing a
risk. The two figures ‘a’ and ‘K’ may
be added together and the resultant
value used to assess the risk.
It should be noted that if a tool is
used under abnormal, or unusual
conditions, then the vibration level
could possibly increase significantly. Users must always take this into account
and make their own risk assessment, using the graph above as a reference.
Some tools with a high vibration value, such as impact wrenches, are
generally used for a few seconds at a time, therefore the cumulative time
may only be in the order of a few minutes per day. Nevertheless, the
cumulative effect, particularly when added to that of other hand held power
tools that may be used, must always be taken into account when the total
daily dose rate is determined.
