COMPRESSED AIR REQUIREMENTS
• Use only clean, dry, regulated compressed air as a power source.
• Air compressors used with the tool 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 tool. 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.
• For optimum performance it is recommended that a 3/8” ID hose is
used.
• 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 dirty air will shorten
the life of the tool due to faster wear and is a possible safety hazard.
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF
COMPRESSORS AND COMPRESSED AIR SUPPLY.

OPERATION
1. Connect the gun to a suitable water supply using a standard snap-on hose
connector. The gun should be connected to a pressurised water supply or
it will function at a significantly reduced rate.
2. Set the compressed air pressure to suit at the compressed airline regulator
and set the water pressure at the tap.
3. The water flow adjusting knob (item 6 on page 7) must be rotated to
obtain the required spray volume. The direction of rotation (+/-) is marked
on the nozzle.
DISCONNECTING THE AIR SUPPLY
1. Do not disconnect the air supply hose until the compressor has been shut
down and the compressed air released.
2. Refer to the compressor instruction manual for the procedure to shut down
and vent the compressed air.
3. Once the pressure has been released, disconnect the air supply hose from
the air tool.
MAINTENANCE
1. Clean thoroughly after use with a suitable solvent (one that will not harm
the O-rings or plastic parts).
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.
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, contact the Clarke service department.
WARNING: MAKE SURE THAT THE AIR TOOL IS DISCONNECTED FROM THE
AIR SUPPLY BEFORE STARTING ANY CLEANING, OR MAINTENANCE
PROCEDURES.
