THE COMPRESSED AIR SUPPLY

AIR SUPPLY 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 air tool.

• A typical air line layout is shown above. If an automatic in-line filter/

regulator is used, it will keep the air 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.

6

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

• The minimum hose diameter should be 5/16”(8mm) ID and fittings

should have the same internal dimensions.

• 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

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.

NOTE: Ensure the air supply is turned off.

1. Remove the protective plug from
the air inlet and connect a suitable
hose as shown.

2. Connect 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 useful for

sealing threaded connections.

4. If required, connect an in-line mini oiler to the drill.

• A mini oiler helps to prolong the life of any air tool.

5. 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 airline inlet or via the hose at the
nearest connection to the air supply.

6. A gauze filter is fitted within the air inlet. Ensure this filter is always in place
and is kept clean. An air line is connected to the adapter, preferably via a
quick release coupling (not supplied).

7. Ensure the trigger is NOT depressed when connecting the air line.

• Your drill is now ready for use

• You can fit a whip hose with a quick fit coupling if required

(available from your Clarke dealer.)

body of the drill, ensuring it rests
against the flat shoulder shown.

2. Twist the handle to tighten the
clamping ring around the drill
body.

• The handle can be rotated to

any position around the drill by
loosening the handle and adjusting its position.

INSERTING/REMOVING THE DRILL BIT

1. Open the chuck jaws by gripping
the lower part of the chuck and
turning the upper part counter­clockwise by hand.

• The direction of twist is

embossed on the upper chuck
body.

2. Place the drill bit in the jaws of the
chuck as far as it will go.

3. Close the chuck jaws and tighten
to grip the drill bit by turning the upper chuck clockwise by hand while
holding the lower part.

firmly.

5. Your drill is now ready for use.

OPERATION

OPERATING THE DRILL

1. Squeeze the trigger to start the
drill.

2. Release the trigger to stop the drill.

3. To change the direction of rotation
move the lever behind the trigger
from F to R.

4. Always ensure the drill has stopped
before putting it down.

DISCONNECTING THE AIR SUPPLY

1. Do not disconnect the air supply hose until the air supply has been shut
down and the compressed air released from the hose.

• 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 drill.

MAINTENANCE

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

Please note that factors other than the drills condition 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.

DAILY

1. Before use, drain water from the air-line and compressor.

2. Lubricate the drill daily for optimum performance. Use a high quality airline
oil either via a lubricator in the air supply system or by placing a few drops
into the air inlet immediately before use. This should be carried out
regardless of whether or not an in-line lubricator is used.

CLEANING & OVERHAUL

1. Keep the drill clean and free from debris.

2. If the drill becomes sluggish and the air supply is of good quality, it may be
necessary to replace worn or damaged parts.

3. Grit or gum deposits in the
mechanism may eventually
reduce efficiency. This condition
can be corrected by cleaning the
air inlet filter and flushing out the
drill with gum solvent oil or an
equal mixture of SAE No10 oil and
paraffin.

4. Failing this, the drill should be
disassembled, thoroughly
cleaned, dried and reassembled.
You may prefer to take the drill to your CLARKE dealer if internal
maintenance is required.

STORAGE

If the drill 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.

When not in use, the drill should be disconnected from the air supply and
stored in a dry place out of the reach of children. Avoid storing in a damp
environment.

ACCESSORIES

A wide range of accessories is available including filter/regulators, lubricators,
high-pressure hoses (5 to 50 metres) etc.

Contact your CLARKE dealer for further information or CLARKE International
Service Department on 01992 565333.

**Clarke Air Line Oil (part no. 3050825) is available from your CLARKE dealer.
