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.
• 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 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.
• If an unusually long air hose is required, (over 8 metres), line pressure may
need to be increased.
• Never exceed the maximum operating pressure for the tool.
• The air hose must be rated at least 150% of the maximum operating
pressure of the tool.
5
• A pressure of 90 psi with a flow of 7.44 cfm is required. Too high an air
pressure will shorten the life of the tool due to excessive wear.
A typical airline layout is shown. 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 air 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 fitting.
BEFORE USE
CONNECTING THE 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 SUPPLIES.
Note: Ensure the compressor is turned off.
1. Remove the plastic blanking plug from the connection port of the tool as
shown.
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.
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.
6
OPERATION
CAUTION: ALWAYS BE SURE THAT THE TOOL IS OFF BEFORE ATTACHING
OR REMOVING A SOCKET. ALWAYS TAKE CARE TO USE THE CORRECT
SIZE SOCKET FOR BOLTS AND NUTS. AN INCORRECT SOCKET WILL CAUSE
DAMAGE TO THE BOLT OR NUT.
1. The side handle is supplied loose and must be fitted to the impact wrench
using the bolt provided.
2. Select an appropriate impact socket, which must be in good condition,
and fits the anvil and nut closely. Use only 1”square drive impact wrench
sockets. (NEVER use standard hand sockets).
3. Select Forward or Reverse drive by moving the lever, on the base of the
wrench, to the ‘F’ or ‘R’ position. Always check the direction of rotation
before operation. Select the appropriate lever when the spindle is
moving.
4. Squeeze the trigger to start the wrench. Release the trigger to stop.
5. Turn the airline regulator to its lowest setting, then apply the wrench to a
nut or bolt of known tightness (or torque setting), size, thread pitch, and
thread condition as those on the job.
6. Start the wrench, in the FORWARD position, and gradually turn the air
regulator until the nut or bolt moves very slightly in the direction in which it
was set. The tool is now set to duplicate that tightness. For future use, note
that specific setting.
7. When critical torque values are not required, turn nut or bolt until it fits
snugly, and then turn a further one quarter to one half a turn - slightly
more if gaskets are used between surfaces.
8. For additional power during disassembly work, turn the air line regulator to
its highest setting.
This tool is rated at 1" bolt size, and is downgraded for spring ‘U’ bolts, tie
bolts, long cap screws, double depth nuts, badly rusted conditions, and
spring loaded fasteners as these conditions absorb much of the impact
power.
9. Turn off the wrench as soon as the impact sound is heard.
IMPORTANT: Where the torque setting is critical, the final tightening of nuts or
bolts, must be by hand using a properly calibrated torque wrench.
7
LOOSENING A WHEEL NUT
1. Remove any wheel trim, before selecting the appropriate socket and
placing firmly on the square drive of the wrench.
2. With the FORWARD/NEUTRAL/REVERSE switch in the REVERSE running
position, and holding the wrench firmly in BOTH HANDS, pull the trigger. The
nut will be impacted repeatedly until it is loosened. IMPORTANT! Release
the trigger immediately the nut begins to loosen.
3. Jack up the vehicle according to the vehicles handbook so that the
wheel is clear of the ground, then proceed to fully undo the wheel nuts.
4. Soak rusted nuts in penetrating oil, and break rust seal before twisting off
with the wrench.
ENSURE THAT THE CORRECT SOCKET IS BEING USED FOR THE NUTS ON
YOUR PARTICULAR VEHICLE. AN INCORRECT SOCKET SIZE IS LIKELY TO
DAMAGE THE HEADS OF THE BOLTS/NUTS.
TIGHTENING A NUT
1
Start the nut by hand, ensuring it is not cross threaded, then with the
appropriate socket installed on the wrench, place it on the nut.
2. With the FORWARD/NEUTRAL/REVERSE switch in the clockwise (FORWARD)
running position, and holding the wrench firmly in BOTH HANDS, pull the
trigger.
3. Run each nut up in turn until it is ‘nipped’ up only - do not tighten. When
all nuts are nipped up, tighten progressively by pulling the trigger fully and
allowing the action to operate for 3 to 4 impacts only to prevent
overtightening.
4. ALWAYS finish tightening with a torque wrench. The weight of the vehicle
will need to be placed on the wheel to prevent it from rotating while the
nuts are tightened. Ensure the final torque applied to the nuts meets the
vehicle manufacturer’s recommendations.
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.
MAINTENANCE
DAILY
1. Before use, drain water from air reservoir, air line and compressor as
appropriate.
8
2. If no line lubricator is used, ensure that oil is applied to the tool on a daily
basis through the air inlet connection.
3. For lubricating the air motor, an air line lubricator should be used,
containing Clarke Air Line Oil, adjusted to 2 drops per minute. If this is not
possible, run a few drops of oil through the tool. 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. Then operate the tool.
Clarke Air-line Oil is available from your Clarke dealer, part no 3050825.
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.
3. 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.
4. Clean the air inlet filter screen.
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 hammer
mechanism and replace worn or damaged parts. You may prefer to take
the tool to your Clarke dealer if internal maintenance is required.
Your Clarke Impact Wrench 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.
General
1. Keep the tool clean at all times, and ensure that the bolts securing the
case remain tight.
• All bearings etc, in this machine are lubricated with sufficient high grade
lubricant for the machines lifetime under normal operating conditions,
therefore no further lubrication is required.
• Be aware that outside factors may effect the wrench’s operation and
efficiency, These may include reduced compressor output, excessive
drain on the airline, moisture in suspension or restrictions in the line, or the
use of connectors of improper size or poor condition which will reduce air
supply.
SERVICE AND REPAIR
• Any major servicing and repairs should be carried out by your local Clarke
dealer or a qualified service technician.
9
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.
**Clarke Airline Oil is available from your Clarke dealer: Part no 3050825.

VIBRATION EMISSIONS
HAND-ARM VIBRATION
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.
MODEL No:
CAT47
DESCRIPTION:
IMPACT WRENCH
Declared vibration emission value in accordance
with EN12096
Measured vibration emission value - a:
5.8m/s2
Uncertainty value - K:
1.5m/s2
Values determined according to EN28622-1
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/s2 are considered hazardous when used for
prolonged periods. A tool with a vibration value of 2.8 m/s2 may 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.
