COMPRESSED AIR REQUIREMENTS
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF
COMPRESSORS AND COMPRESSED AIR SUPPLY.
• Use only clean, dry, regulated compressed air as a power source.
• 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. ensure any moisture is
drained from the compressor daily and the inlet filter is kept clean.
• If an unusually long air hose is required, (over 8 metres), the line
pressure or the hose inside diameter may need to be increased.
• The air hose must be rated at least 150% of the maximum operating
pressure of the tool.
• A typical air line layout is shown above. If an automatic in-line filter/
regulator is used, it will keep the tool in good condition, but should
be regularly checked and topped up with oil. SAE 10 oil should be
used, and the lubricator adjusted to approx 2 drops per minute.
• Never exceed the maximum operating pressure for the tool. It is
recommended that air pressure to this tool does not exceed 90 psi
at the tool when running. Higher pressures and unclean air will
shorten the life of the tool due to faster wear and is a possible safety
hazard.

OPERATION
NOTE: Ensure the compressed air supply is turned off.
1. If required, connect an in-line mini oiler to the tool.
• A mini oiler helps to prolong the life of the air tool. Read the
instructions supplied with the mini-oiler before use.
NOTE: If a mini-oiler is not being used, insert a few drops of oil into the tool
through the air inlet before use.
NOTE: Ensure the compressed air supply is turned off.

1. If required, connect an in-line mini oiler to the tool.
• A mini oiler helps to prolong the life of the air tool. Read the
instructions supplied with the mini-oiler before use.
2. Connect a suitable hose to the tool and the other end of the hose to the
compressed air supply.
3. Turn on the air supply and check for air leaks. Rectify any found before
proceeding.
• PTFE tape may be helpful for sealing threaded connections.
• Your air tool is now ready for use.
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 chisel into the air
hammer as shown.
3. Replace the retaining spring as
shown.
• Use the lugs to tighten.
USING THE AIR HAMMER
1. Hold the tool firmly, then bring it
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. To remove scale, rust or
other contaminants, only a light
force should be required.
4. Release the trigger to stop operation, whilst maintaining contact with the
work.
5. Chisel force may be adjusted by turning the regulator knob, located at the
base of the handle grip. Turn anti-clockwise (unscrew) to increase force,
clockwise (screw in) to reduce.
NOTE: that the tool may impact briefly after the trigger is released.

• The retaining spring has a life expectancy, depending upon the
intensity of usage. It is recommended that you procure a spare
spring 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 air supply has been shut down
and the compressed air pressure released. Refer to the compressor instruction
manual for the procedure to shut down and release the compressed air. Once
the pressure has been released, disconnect the air supply hose from the tool.
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. Clarke air-line oil is available from your Clarke
dealer, part no. 3050825.

MAINTENANCE
WARNING: MAKE SURE THAT THE TOOL IS DISCONNECTED FROM THE AIR
SUPPLY BEFORE STARTING ANY CLEANING, OR MAINTENANCE
PROCEDURES.
DAILY
1. Before use, drain water from the air tank, air line and compressor.
2. Pour a few drops of CLARKE airline oil, into the air inlet. This should be
carried out regardless of whether or not an in-line mini oiler is used. If an
inline mini oiler is not used, this procedure should be repeated after every
two to three hours of use.
3. Check the air inlet screen filter for blockage and clean if necessary.
CLEANING
1. Keep the body of the tool clean and free from debris.
2. Grit or gum deposits in the tool may also reduce efficiency. This condition
can be corrected by cleaning the air strainer and flushing out the tool with
gum solvent oil, or failing this, the tool should be disassembled, thoroughly
cleaned, dried and reassembled.
3. After extensive use, remove the inlet screen filter and flush out the
mechanism with gum solvent oil or an equal mixture of SAE No10 oil and
paraffin. Allow to dry before use.
4. If the tool runs erratically or becomes inefficient, and the air supply is of
good quality, it may be necessary to dismantle the air motor and replace
worn or damaged parts. You may prefer to take the tool to your CLARKE
dealer if internal maintenance is required.
Your Clarke air tool has been designed to give long and trouble free service. If,
however, having followed the instructions in this booklet carefully, you
encounter problems, take the unit to your local Clarke dealer.
PERFORMANCE
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 air-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.
