SAFETY PRECAUTIONS
WORK ENVIRONMENT
• Keep the work area clean and tidy.
• Dress appropriately - Do not wear loose clothing or jewellery. Tie long hair
out of the way.
• Keep children and visitors away - Do not let children handle the tool.
Make sure that any other persons in the work area are dressed suitably
and are wearing eye and ear protectors.
• Keep the air supply hose away from heat, oil and sharp edges.
• Do not fit the tool to any stand or clamping device that may damage the
tool.
GENERAL USE
• Stay alert and use common sense - do not use the tool when you are tired
or under the influence of alcohol, drugs or medication.
• Always wear eye protection when using the tool - eye protection must
provide protection from the front and the side.
• Always wear ear protectors when using the tool.
• Do not over-reach - keep proper footing and balance at all times.
• Never use any type of bottled gas as a source of power for the tool.
• Do not connect the air supply hose with your finger on the trigger of the
tool.
• Do not exceed the maximum pressure for the tool: 90 psi / 6.2 bar.
• Check hoses for leaks or worn condition before use and ensure that all
connections are secure.
• Do not use the tool for any other purpose than that described in this
booklet.
• Do not carry out any alterations or modifications to the tool.
• The tool should be serviced as required by your CLARKE dealer.
• Never use the tool if it is defective or operating abnormally.
• ALWAYS ensure the workpiece is firmly secured leaving both hands free to
control the tool.
• ALWAYS ensure the tool has stopped before putting it down after use.
• ALWAYS ensure that any attachments are correctly fastened before
connecting the tool to the power supply.

5
• Always disconnect from the air supply when:
a) Performing any maintenance.
b) The tool is not in use.
c) The tool will be left unattended.
d) Moving to another work area.
• Avoid damaging the tool for example by applying excessive force.
• ALWAYS maintain the tool with care. Keep it clean for best and safest
performance.
• Quick change air-line couplings should not be located at the tool. They
add weight and could fail due to vibration.
• DO NOT force or misuse the tool. It will do a better and safer job at the
rate for which it was designed.
• This tool vibrates during use. Vibration may be harmful to your hands or
arms. Stop using the tool if discomfort, a tingling feeling or pain occurs and
seek medical advice before resuming use.
TRANSPORTATION
• Never carry the tool by the air supply hose.
• Never carry the tool with your finger on the trigger.
STORAGE
• When not in use the tool must be disconnected from the air supply and
stored in a dry place out of the reach of children (preferably in a locked
cabinet).
• Avoid storage in environments where the temperature is below 0oC.
AIR SUPPLY REQUIREMENTS
WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU
ARE THOROUGHLY FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE
USE OF COMPRESSORS AND COMPRESSED AIR SUPPLY.
• Air compressors used with the tool must comply with the appropriate
European Community safety directives.
• Use only clean, dry, regulated compressed air as a power source.
• A build up of moisture in the air compressor will accelerate wear and
corrosion in the moving parts. Ensure any moisture is drained from the
compressor daily and the inlet filter is kept clean.

ASSEMBLY
1. Remove the plastic blanking plug from the connection port of the tool as
shown in Fig 1.
2. Pour 2-3 drops of CLARKE airline oil into
the air inlet. This should be done
regardless of whether or not a
lubricated air supply is to be used.
3. Connect a suitable hose to the tool as
shown. Use the screw-in adapter
supplied if required.
4. Connect the other end of the hose to
the compressor.
(A whip hose with a quick fit coupling is
available from your CLARKE dealer).
5. Turn on the air supply and check for air
leaks. Rectify any found before
proceding.
The tool is now ready for use.
• If an unusually long air hose is required, (over 8 metres), line presure may
need to be increased.
A typical airline layout is
shown on the right. If an
automatic in-line filter/
regulator/lubricator unit
is used it will keep the
tool in good condition,
but should be regularly
checked and topped
up with oil.
IMPORTANT: If a filter/
lubricator unit is not used, the tool should be lubricated with 2 to 6 drops of oil,
at least once a day or after 2 hours work, depending upon the working
environment. The oil can be inserted through the airline connection point.
AIRLINE SAFETY
• Never exceed the maximum operating pressure for the tool. A pressure of
90psi with a flow of 4 cfm is required. Too high an air pressure will shorten
the life of the tool due to excessive wear.
• The air hose must be rated at least 150% of the maximum operating
pressure of the tool.

OPERATING INSTRUCTIONS
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.
2. Press the socket until it clicks into
place on the square drive.
3. Place the socket over the subject
nut.
• Take care that the socket is firmly
engaged on the nut to be
tightened or removed.
4. Squeeze the trigger against the
body of the tool to start as in Fig
2.
5. Release the trigger to stop the
tool.
6. Always ensure the tool has
stopped before putting it down.
7. To change the direction, twist the
control at the tip of the tool to
either ‘F’ for forward or ‘R’ for
reverse as in Fig 3.
DISCONNECTING THE AIR SUPPLY
1. Do not disconnect the air supply hose until the compressor has been shut
down and the compressed air pressure released.
2. Once the pressure has been released, disconnect the air supply hose from
the tool.
STORAGE
1. Store the tool safely in its box in a dry, secure environment.
2. If the tool is not to be used for longer than 24 hours, run a few drops of
CLARKE airline oil into the air inlet and run the tool for a few seconds to
ensure that the oil has been well distributed throughout the tool.
3. When storing, ensure the blanking plug is replaced on the airline
connector once the airline has been disconnected.

MAINTENANCE
WARNING! Make sure that the ratchet wrench is disconnected from the air
supply before starting any cleaning or maintenance procedures.
DAILY
• Drain water from the compressor air
tank and air-line.
• Pour a few drops of CLARKE air line
oil**, into the air inlet. This should be
carried out regardless of whether or
not an air line lubricator is used. If an
air-line lubricator is not used, this
procedure should be repeated after
every two to three hours of use.
WEEKLY
• Check the air inlet screen filter shown
in Fig 4 and clean if necessary.
CLEANING
• Keep the body of the tool clean and free from debris. Grit or gum deposits
in the tool may reduce efficiency.
• After extensive use, remove the inlet screen filter and flush out the
mechanism with gum solvent oil or an equal mixture of SAE No10 oil and
paraffin. Allow to dry before use.
SERVICE AND REPAIR
• Any major servicing and repairs should be carried out by your local
CLARKE dealer.
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 line, or the use of connectors of improper size or
poor condition which will reduce air supply.

VIBRATION EMISSIONS
MODEL No: CAT108 & CAT109
DESCRIPTION: REVERSIBLE RATCHETS
Declared vibration emission value in accordance
with EN12096
Measured vibration emission value - a: less than
2.5m/s2
Values determined according to EN28622-1
Employers are advised to refer to the HSE publication “Guide for Employers”.
All hand held power tools vibrate to some extent, and this vibration is
transmitted to the operator via the handle, or hand used to steady the tool.
Vibration from about 2 to 1500 herz is potentially damaging and is most
hazardous in the range from about 5 to 20 herz.
Operators who are regularly exposed to vibration may suffer from Hand Arm
Vibration Syndrome (HAVS), which includes ‘dead hand’, ‘dead finger’, and
‘white finger’. These are painful conditions and are widespread in industries
where vibrating tools are used.
The health risk depends upon the vibration level and the length of time of
exposure to it……in effect, a daily vibration dose.
Tools are tested using specialised equipment, to approximate the vibration
level generated under normal, acceptable operating conditions for the tool
in question. For example, a grinder used at 45° on mild steel plate, or a
sander on softwood in a horizontal plane etc.
These tests produce a value ‘a
’ , expressed in metres per second per second,
which represents the average vibration level of all tests taken, in three axes
where necessary, and a second figure ‘K’, which represents the uncertainty
factor, i.e. a value in excess of ‘a’, to which the tool could vibrate under
normal conditions. These values appear in the specification panel below.
HAND-ARM VIBRATION

13
You will note that a third value is given in the specification - the highest
measured reading in a single plane. This is the maximum level of vibration
measured during testing in one of the axes, and this should also be taken into
account when making a risk assessment.
‘
a ’ values in excess of 2.5 m/s2are considered hazardous when used for
prolonged periods. A tool with a vibration value of 2.8 m/s2may be used for
up to 8 hours (cumulative) per day, whereas a tool with a value of 11.2 m/s2
may be used for ½ hour per day only.
The graph below shows the vibration value against the maximum time the
respective tool may be used, per day.
The uncertainty factor should also be taken into account when assessing a
risk. The two figures ‘ a ’ and ‘ K ’may be added together and the resultant
value used to assess the risk.
It should be noted that if a tool is used under abnormal, or unusual conditions,
then the vibration level could possibly increase significantly. Users must always
take this into account and make their own risk assessment, using the graph
above as a reference.
Some tools with a high vibration value, such as impact wrenches, are
generally used for a few seconds at a time, therefore the cumulative time
may only be in the order of a few minutes per day. Nevertheless, the
cumulative effect, particularly when added to that of other hand held power
tools that may be used, must always be taken into account when the total
daily dose rate is determined.
