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 and topped up with oil. clarke airline oil should
be used, and the lubricator adjusted to approx 2 drops per minute.

• For optimum performance it is recommended that a minimum 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.

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

NOTE: Ensure the air supply 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. Read the

instructions supplied with the mini-oiler before use.

2. If a mini-oiler is not being used, insert a few drops of oil into the tool through
the air inlet before use.

3. Connect a suitable hose as shown.

4. Connect the other end of the hose
to the compressed air supply.

5. Turn on the air supply and check
for air leaks.

• Rectify any found before

proceeding. PTFE tape may be
useful for sealing threaded
connections.

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).

ACCESSORIES

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

• Contact your Clarke dealer or the Clarke International Service

Department for further information.

BEFORE OPERATING THE DIRECTION CONTROL.

To select the direction of rotation turn
the direction control as follows.

• For tightening, turn the direction

control anti-clockwise to F
(Forward).

• For loosening, turn the direction

control clockwise to R (Reverse).

USING THE AIR RATCHET

1. Select the socket you require.

• Push the socket onto the square

drive shaft. It clicks into place
when secure.

2. Place the socket over the nut.

firmly engaged.

3. Squeeze the trigger against the
body of the tool to start.

4. Release the trigger to stop the tool.

5. Always ensure the tool has stopped before putting it down.

6. When releasing very tight fastenings initially break loose by hand. Squeeze
the trigger and the air tool will complete the job.

7. If necessary, use penetrating oil to assist in freeing off rusted fasteners.

8. When assembling, start turning fasteners by hand, then set the rotation
forward or reverse. Apply the tool gently and squeeze the trigger to tighten
with power.

9. Final tightening should be completed by hand.

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.

TROUBLESHOOTING

SYMPTOM PROBLEM SOLUTION

speed but slows down
under any load.

Tool runs slowly. Air flows
weakly from exhaust.

Tool will not run. Air flows
freely from exhaust.

2. Worn or sticking
mechanism due to
lack of lubricant.

1. Motor parts jammed
with gum/dirt.

2. Air-line regulator in
closed position.

3. General airflow
blocked by dirt.

1. Motor vanes stuck
due to buildup of
foreign material.

1. Return to Clarke dealer
for repair.

2. Drip air tool lubricating
oil into air inlet. Allow oil
to soak moving parts
before using.

1. Examine inlet air filter for
blockage. Drip a few
drops of air tool lubricat­ ing oil into air inlet.

2. Adjust in-line regulator to
open position.

3. Operate tool in short
bursts.

1. Disconnect air supply
and rotate tool assembly
manually.

2. Try operating tool in
short bursts.

3. Tap motor housing gently

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. Pour a few drops of Clarke air-line oil, into the tool air inlet. This should be
carried out regardless of whether or not an in-line mini oiler is used. If an in­line mini oiler is not used, this procedure should be repeated after every
two to three hours of use.

WEEKLY

1. Check the air inlet screen filter for
blockage and clean if necessary.

CLEANING

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

2. Grit or gum deposits in the tool
may also reduce efficiency. This
condition can be corrected by
cleaning the air strainer and
flushing out the tool with gum solvent oil, or failing this, the tool should be
disassembled, thoroughly cleaned, dried and reassembled. This is better
left to your Clarke dealer.

3. 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.

4. Clean the air inlet filter screen inside the air inlet.

5. If the tool 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 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.

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.

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 run the tool for 5 seconds in order to
lubricate the internal parts.

When not in use, disconnect from air supply, clean & store in a safe, dry place.
