COMPRESSED AIR REQUIREMENTS
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.
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.

6
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
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.
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.
Set the tool in the OFF position before connecting it to the air supply.
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 by up to 15 psi 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 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.
USEFUL ACCESSORIES
A wide range of accessories are available including filter/regulators,
lubricators, high pressure hoses, etc. Contact your CLARKE dealer for further
information, or call CLARKE International on 01992 565333.

BEFORE USE
CONNECTING THE AIRLINE
NOTE: Ensure the air supply is turned off.
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 to be used.
3. If required, connect an in-line mini
oiler to the tool. Refer to the
instructions supplied with the mini-
oiler 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. 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.
6. Connect the other end of the hose to the compressor.
7. 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.
8. Place a sheet of paper next the exhaust port and hold the throttle open 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.
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).
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.

OPERATION
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 anti-
clockwise to F (Forward).
• For loosening bolts/nuts, turn the
direction control clockwise to R
(Reverse).
FITTING SOCKETS AND USING THE AIR RATCHET
IMPORTANT: Only use sockets designed for use with a ratchet wrench;-
either 3/8" (10mm) for the CAT109 or 1/2” (13mm) for the CAT108.
1. Select the socket you require 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.
WARNING: ALWAYS WAIT UNTIL THE DRIVE SHAFT HAS STOPPED ROTATING
BEFORE SETTING THE DIRECTION CONTROL.

9. Final tightening should be completed by hand to the required torque
settings.
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
When not in use, disconnect from the air supply, clean & store in a safe, dry
place.
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 storing, replace the blanking plug on the
airline inlet.
Avoid storing the tool where the temperature is below 0oC.

MAINTENANCE
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.
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.
WEEKLY
1. Check the air inlet screen filter for
blockage and clean if necessary.
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 effect the operation and efficiency of
the 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.
WARNING: MAKE SURE THAT THE AIR TOOL IS DISCONNECTED FROM THE
COMPRESSED AIR SUPPLY BEFORE STARTING ANY CLEANING OR
MAINTENANCE PROCEDURES.
