COMPRESSED AIR REQUIREMENTS

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

A typical air line layout is shown below. If an automatic in-line filter/regulator is
used, it will keep air tools in good condition but should be regularly checked
and topped up with oil. CLARKE airline oil should be used and the lubricator
be adjusted to approx 2 drops per minute.

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

5

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

Air compressors used with the tool must comply with the appropriate
European Community Safety Directives.

The air hose must be rated at least 150% of the maximum operating pressure of
the tool.

For optimum performance it is recommended that a 3/8” ID airline hose is
used.

A build-up of moisture or oil in the air compressor will accelerate wear and
corrosion in the air 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 to maintain air pressure at the
tool.

Never exceed the maximum operating pressure for the air tool. It is
recommended that air pressure to this tool does not exceed 90 psi (6.2 Bar) at
the air 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.

Check hoses for wear or damage before use.

BEFORE USE

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

NOTE: Ensure the compressor is turned off.

1. Remove the travel plug and connect either a suitable hose directly or
using the male adaptor supplied.

2. If required, connect an in-line mini
oiler to the tool.

• A mini oiler helps to prolong the

life of any air tool.

3. 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 connector or
via the hose at the nearest
connection to the air supply.

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. Set the
working pressure to 90psi/6.2 bar
for best performance

• PTFE tape may be useful for

sealing threaded connections.

Your air tool is now ready for use.

OPERATION

SETTING THE DIRECTION OF ROTATION

WARNING: ALWAYS WAIT UNTIL THE DRIVE SHAFT HAS STOPPED ROTATING
BEFORE SETTING THE DIRECTION OF ROTATION.

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

• For tightening bolts/nuts, turn

the direction control anti­clockwise to F (Forward).

• For loosening bolts/nuts, turn the

direction control clockwise to R
(Reverse).

FITTING THE SOCKETS AND USING THE WRENCH

1. Select the socket required and
push it onto the square drive shaft.

• It clicks into place when secure.

2. Place the socket over the nut.

• Take care that the socket is

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 to the required torque
values.

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 and drain daily as
recommended.

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.

Store the tool safely in its box in a dry, secure environment. When storing,
replace the blanking plug on the airline inlet once the airline has been
disconnected.

o

Avoid storing the air tool where the temperature is below 0

C.

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 airline filter and compressor.

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. Only then should you 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.

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 reduce efficiency.

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. 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 tool’s 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.
