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 presure 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.

• A pressure of 90psi with a flow of 6 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 COM-

PRESSORS 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.

OPERATION

CAUTION: ALWAYS BE SURE THAT THE TOOL IS SWITCHED 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. Select an appropriate impact socket, which must be in good condition,

and fits the anvil and nut closely. Use only square drive impact wrench

sockets as listed on page 10. (NEVER use standard hand sockets).

2. Select Forward or Reverse drive by moving the rod, in the body 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.

3. Squeeze the trigger to start the wrench. Release the trigger to stop.

4. 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.

5. 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

Parts & Service: 020 8988 7400/E-mail:Part[email protected] or [email protected]

was set. The tool is now set to duplicate that tightness. For future use, note

that specific setting.

6. 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.

7. For additional power during disassembly work, turn the air line regulator to

its highest setting.

This tool is rated at 5/8" 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.

8. 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.

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.

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

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.

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 inside the hose adaptor.

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.

SERVICE AND REPAIRS

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.

• Any major servicing and repairs should be carried out by your local

CLARKE dealer or a qualified service technician.

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.
