from fatigue. Always use sharp tools.

4. NEVER mis-use the tool by prising which can result in a broken tool.

5. ALWAYS ensure there are no hidden electrical cables, gas pipes etc, which
could cause a hazard if damaged by action of the chisels.

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
& topped up with oil. CLARKE air-line oil should be used, and the lubricator
adjusted to approx 2 drops per minute.

5

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

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

Air compressors used with the air 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.

DO NOT exceed the maximum operating pressure for the air 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 an air
tool due to faster wear and is a possible safety hazard.

BEFORE USE

WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF AIR
COMPRESSORS AND A COMPRESSED AIR SUPPLY.

CONNECTING THE AIRLINE

1. Remove the travel plug.

2. Pour 2-3 drops of CLARKE airline oil
into the oil filling port. This should
be done regardless of whether or
not a lubricated air supply is used.

3. If required, connect an in-line mini
oiler to the tool. Read the
instructions supplied with the mini­oiler before use.

• A mini oiler helps to prolong the

life of any air tool.

4. Connect a suitable hose. This can
be done using either the male
adaptor supplied or using a mini
oiler from your CLARKE dealer.

5. Connect the other end of the hose
to the compressor.

• PTFE tape may be useful for

sealing threaded connections.

6. Turn on the air supply and check
for air leaks. Rectify any found
before proceeding. Set the working pressure to 90psi (6.2 bar) for best
performance

7. Place a sheet of paper next the exhaust port and squeeze the trigger for
approximately 30 seconds. The oil volume is correctly set when a light stain
of oil can be seen on the paper. Excessive oil should be avoided.

OPERATION

FITTING THE CHISEL

1. Select which chisel is best
suited to the task. A
selection of chisels is
supplied as shown.

2. First remove the retaining spring
from the nose by unscrewing it.

• Use the inboard lug to gain

purchase.

3. Insert the chisel into the air
hammer as shown.

4. Replace the retaining spring.

• Use the lugs to help tighten.

USING THE AIR HAMMER

1. Hold the tool firmly, then bring the
tool towards the work at an angle
of approximately 60-70 degrees.

2. Squeeze the trigger with the chisel
in light contact with the work.

• The chisel speed is controlled by

squeezing the trigger.

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.

NOTE: The air tool may operate briefly after the trigger is released.

NOTE: 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

1. Do not disconnect the air hose until the supply is isolated at a shut-off
valve.

2. Once the pressure has been isolated, disconnect the air supply hose from
the air tool.

3. Shut down the compressor at the end of the work session.

MAINTENANCE

WARNING: MAKE SURE THAT THE AIR TOOL IS DISCONNECTED FROM THE
COMPRESSED AIR SUPPLY BEFORE STARTING ANY CLEANING OR
MAINTENANCE PROCEDURES.

DAILY

1. Before use, drain water from the compressed air supply.

2. If no line lubricator or mini oiler is used, ensure that oil is applied to the tool
on a daily basis through the air inlet connection. Run a few drops of oil
through the tool before use. It may be entered into the tool air inlet,
(ensuring the strainer is clear), or into the hose at the nearest connection to
the air supply. Then operate the tool.

3. This procedure should be repeated after every two to three hours of use, or
at the start of the working day.

4. Keep the body of the tool clean and free from debris.

CLEANING

1. Grit or gum deposits in the tool may reduce efficiency.

2. After extensive use, remove the inlet screen filter and flush out the
mechanism with gum solvent oil or an equal mixture of CLARKE air-line oil
and paraffin. Allow to dry before use.

3. If the tool still 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.

PERFORMANCE

Please note that outside factors may affect the operation and efficiency of
the air tool, 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 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.

order to lubricate the internal parts.

When storing, replace the blanking plug on the airline inlet once the airline has
been disconnected.
