AIR SUPPLY
• Use only clean, dry, regulated compressed air as a power source for
the Air Hammer.
• Air compressors used with the Air Hammer 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 Air Hammer.
• Never exceed the maximum operating pressure for the Air Hammer.
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
Ensure the compressor is turned off.
1. Remove the travel plug from the
bottom of the tool as shown.
2. Pour 2-3 drops of CLARKE airline oil
into the air inlet. This should be
done regardless of whether or not
a lubricated air supply is to be
used.
3. Connect a suitable hose to the
tool as shown.
• Use the adapter supplied if
required.
4. Connect the other end of the hose
to the compressor.
You can fit a whip hose with a quick fit
coupling if required (available from
your Clarke dealer.)
FITTING THE CHISEL
1. First remove the retaining spring
from the nose by unscrewing it.
• Use the inboard lug to gain
purchase.
2. Insert the end of the chisel into the
air hammer.
3. Replace the retaining spring, as
shown.
• Use the lugs to tighten.

ADJUSTING THE FORCE
Chisel force may be adjusted by
turning the speed controler/air
regulator knob, located at the base
of the handle grip.
• Turn anticlockwise to increase
force.
• Turn clockwise to reduce.the
force.
USING THE AIR HAMMER
1. Hold the tool with one hand
around the handle and one hand
around the barrel, then bring the
tool towards the work at an angle
of approximately 60-70 degrees.
2. Pull the trigger with the chisel in
light contact with the work.
3. Move slowly across the work
surface and proceed to remove
scale, rust or other contaminants, a light force only should be required.
4. Release the trigger to stop operation, whilst maintaining contact with the
work, noting that the tool may impact briefly after the trigger is released.
NOTE: The Retaining Spring has a life expectancy, depending upon the
intensity of usage. It is strongly recommended that you procure
one or two spare springs, for use in the event of failure occurring
during the course of a particular job.
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 book for the procedures to shut down
and release the compressed air.
2. Once the pressure has been released, disconnect the air supply hose from
the tool.
3. Store the tool safely in its box in a dry, secure environment.

MAINTENANCE
DAILY
• Drain water from 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.
• When not in use, disconnect from air supply, clean tool and store in
a safe, dry place.
NOTE: **Clarke Air Line Oil (part no. 3050825) is available from your
CLARKE dealer.
WEEKLY
• Remove the grub screw from the oil port on the side of the Air Hammer
and insert a few drops of oil.
CLEANING
• Keep the body of the tool clean and free from debris, grit or gum
deposits in the tool which may reduce efficiency.
SERVICE AND REPAIR
All servicing and repair must be carried out by qualified service technicians.
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.
WARNING: MAKE SURE THAT THE AIR HAMMER IS DISCONNECTED FROM
THE AIR SUPPLY BEFORE STARTING ANY CLEANING, OR MAINTENANCE
PROCEDURES.

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.
Model Number CAT114
Description Air Hammer
Declared vibration emission value in accordance with EN12096
Measured vibration emission value - a: 14.6 m/s2 at the Main Handle
K = 0.99 m/s2
Value determined according to EN28622-1

Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
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 Air Hammeres, 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.
