GENERAL SAFETY RULES

CAUTION: FAILURE TO FOLLOW THESE PRECAUTIONS COULD RESULT IN
PERSONAL INJURY, AND/OR DAMAGE TO PROPERTY.

WORK ENVIRONMENT

1. Keep the work area clean and tidy.

2. Dress appropriately - Do not wear loose clothing or jewellery. Tie long hair
out of the way.

3. Keep children and visitors away - Do not let children handle the air tool.

4. Do not operate the air tool where there are flammable liquids or gases.

5. Keep the air supply hose away from heat, oil and sharp edges.

6. Do not fit the air tool to any stand or clamping device that may damage
the tool.

USE

1. Stay alert and use common sense - Do not operate the air tool when you
are tired or under the influence of alcohol, drugs or medication.

2. Always wear eye protectors when using the air tool - Eye protectors must
provide protection from flying particles from the front and the side.

3. Always wear ear protectors when using the air tool.

4. Do not overreach - Keep proper footing and balance at all times.

5. Never use any type of bottled gas as a source of power for the air tool.

6. Do not connect the air supply hose with your finger on the trigger of the air
tool.

7. Do not exceed the maximum pressure of 90 psi / 6.2 bar.

8. Check hoses for leaks or worn condition before use, and ensure that all
connections are secure.

BEFORE USE

AIR SUPPLY

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

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

the ratchet.

• Air compressors used with the ratchet must comply with the

appropriate EC safety directives.

• A build up of moisture or oil in the air compressor will accelerate

wear and corrosion in the ratchet.

• Never exceed the maximum operating pressure for the ratchet.

AIR HOSE

• The air hose must be rated at least 150% of the maximum operating

pressure of the tool.

DISCONNECTING THE AIR SUPPLY

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

1. Refer to the compressor instruction book for the procedures to shut down
and release the compressed air.

2. Once the pressure has been released, disconnect the air supply hose from
the ratchet.

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 tool and store in

a safe,dry place.

• Store the ratchet safely in its box in a dry, secure environment.

ACCESSORIES

A wide range of accessories are available, including Filter/Regulators,
Lubricators, High Pressure Hoses (5 to 100 Metres), etc.

MAINTENANCE

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

DAILY

• Drain water from air tank, air line and compressor.

• Pour a few drops of CLARKE air line oil, into the air inlet. This should be

carried out regardless of whether or not the inline mini oiler is used. If
the inline mini oiler is not used, this procedure should be repeated
after every two to three hours of use.

CLEANING

• Keep the body of the ratchet clean and free from debris, grit or gum

deposits.

SERVICE AND REPAIR

• All servicing and repair must be carried out by qualified service

technicians.

NOTES

• Please note that factors other than the tool may effect its operation

and efficiency such as reduced compressor output, excessive
demand 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.

• **Clarke air line oil (part no. 3050825) is available from your CLARKE

dealer.

VIBRATION EMMISIONS

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 soft wood 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.

Model Number CAT115

Description Reversible Rachet

Declared vibration emission value in accordance with EN12096

Measured vibration emission value - a:

Value determined according to EN28622-1

1.2 m/s

2

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.

2

‘a’ values in excess of 2.5 m/s

are considered hazardous when used for

prolonged periods. A tool with a vibration value of 2.8 m/s2 may be used for

2

up to 8 hours (cumulative) per day, whereas a tool with a value of 11.2 m/s
may be used for ½ hour per day only.

12

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

The graph on the right 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 ratchetes, 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.
