USE

1. Stay alert and use common sense - do not operate this tool when you are

source of power for the grease gun. This product should only be used with
a suitably rated compressed air supply.

5. Do not connect the air supply hose with your finger on the trigger of the
gun.

6. Do not exceed the maximum pressure for the gun of 90 psi / 6.2 bar.

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.

A typical air line layout is shown below. 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.

.

Use only clean, dry, regulated compressed air as a power source.

6

Parts & Service: 020 8988 7400 / E-mail: [email protected] or [email protected]

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 air tool.

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).

OPERATION

LOADING WITH GREASE

This air driven grease gun is designed to be loaded in one of three ways:

• Using a standard 400 gram grease cartridge.

• Loading the container with a filler pump.

• Loading the container by bulk filling.

WARNING: MAKE SURE THE AIR SUPPLY IS DISCONNECTED BEFORE FILLING
THE GREASE CHAMBER.

CARTRIDGE LOADING

head of the grease gun.

2. Pull the plunger handle on the
container completely out.

3. Remove any seal or end cap from
the end of the grease cartridge.

4. Insert the grease cartridge all the
way into the container.

5. Re-fit the container to the head of
the grease gun.

6. Press the handle release tab to release the plunger handle.

7. Press the air vent valve to release any excess air trapped inside the gun.

LOADING USING A FILLER PUMP (IF AVAILABLE)

1. Pull the plunger handle on the container completely out.

2. Fit the filler pump to the grease gun inlet valve.

3. Fill the container by pumping the filler pump handle.

4. Disconnect the grease gun inlet valve from the filler pump.

5. Press the handle release tab to release the plunger handle.

BULK FILL LOADING

1. Remove the container from the head of the grease gun.

2. Pull the plunger handle on the container completely out.

3. Fill the container with bulk grease.

4. Re-fit the container to the grease gun.

5. Press the handle release tab to release the plunger handle.

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

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 air tool.

3. Store the tool safely in its box in a dry, secure environment.

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-lne 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.
