COMPRESSED AIR REQUIREMENTS
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF
COMPRESSORS AND A COMPRESSED AIR SUPPLY.
• 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, but should
be regularly checked & topped up with oil. Clarke air-line 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.

BEFORE USE
NOTE: Ensure the compressor 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.
2. If a mini-oiler is not being used, run a few drops of oil through the tool
before use. It can be entered through the inlet connector or via the hose
at the nearest connection to the air supply.
3. Connect a suitable hose as shown.
4. Connect the other end of the hose
to the compressor.
5. Turn on the air supply and check
for air leaks. Rectify any found
before proceeding. PTFE tape may
be helpful for sealing threaded
connections.
6. Your air tool is now ready for use.
You can fit a whip hose with a quick fit coupling if required (available from
your Clarke dealer).

6. Press the air vent valve to release any excess air trapped inside.
OPERATING THE GREASE GUN
1. Connect the gun to the air hose.
NOTE: It is recommended that a whip hose with a swivel (not included)
be used to prevent twisting, kinking and resultant wear to the air
hose.
2. Squeeze the trigger completely to operate the grease gun.
• The grease is applied in shots, not in a continuous flow.
3. Release the trigger after each shot.
DISCONNECTING THE AIR SUPPLY

MAINTENANCE
WARNING: MAKE SURE THAT THE AIR TOOL IS DISCONNECTED FROM THE
AIR SUPPLY BEFORE STARTING ANY CLEANING, OR MAINTENANCE
PROCEDURES.
DAILY
1. Before use, drain water from the air-line and compressor.
2. This air tool should be lubricated before use. Turn the tool upside down and
pour 1-2 drops of Clarke air-line oil into the air inlet. This should be carried
out regardless of whether or not an in-line mini oiler is used. If an in-line mini
oiler is not used, this procedure should be repeated after every two to
three hours of constant use.
CLEANING
1. Keep the body and nozzle of the tool clean.
2. Deposits in the tool may also reduce efficiency. This can be corrected by
cleaning the air inlet and flushing out the tool with gum solvent oil, or failing
this, the tool should be disassembled, thoroughly cleaned, dried and
reassembled.
3. If the tool becomes inefficient and the air supply is of good quality, it may
be necessary to 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.
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 depress the trigger in order to lubricate
the internal parts.
