Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com COMPRESSED AIR REQUIREMENTS A typical air line layout is shown below. If an automatic in-line filter/regulator is used, it will keep the tool in good condition, but should be regularly checked and topped up with oil. CLARKE airline oil should be used and the lubricator 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 COMPRESSED AIR SUPPLY.
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com A build-up of moisture or oil in the air compressor will accelerate wear and corrosion in the 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. The air hose must be rated at least 150% of the maximum operating pressure of the tool. For best performance it is recommended that a 3/8” ID hose is used. Never exceed the maximum operating pressure for the tool. It is recommended that air pressure to this tool does not exceed 90 psi at the 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.

Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com BEFORE USE NOTE: Ensure the compressor is turned off. 1. Remove the plastic blanking plug from the air inlet connection. 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 a CAT150 in- line mini oiler to the tool. A mini oiler helps to prolong the life of any air tool. 4. Connect a suitable hose as shown or use the snap connector supplied to connect directly to the hose. 5. Connect the other end of the hose to the compressor. 6. Turn on the air supply and check for air leaks. Rectify any found before proceeding. PTFE tape may be useful for sealing threaded connections. 7. If using a mini oiler, 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 impact wrench is now ready for use. WARNING: COMPRESSED AIR CAN BE DANGEROUS. ENSURE THAT YOU ARE FAMILIAR WITH ALL PRECAUTIONS RELATING TO THE USE OF AIR COMPRESSORS AND COMPRESSED AIR SUPPLY.

Select the impact socket you require which must be in good condition and fit the tool exactly. 2. Push the socket onto the square drive shaft. SETTING THE DIRECTION AND SPEED 1. To adjust the speed, move the switch left or right until the desired output is achieved. The embossed dots give an indication of the power and the embossed arrows indicate the direction. (3 speed forward and 1 speed reverse) For normal tightening, the wrench should be operated in the forward direction. For loosening, the wrench should be operated in the reverse direction. WARNING: NEVER USE STANDARD SOCKETS. THESE MAY SHATTER WITH SERIOUS CONSEQUENCES. ONLY USE IMPACT SOCKETS DESIGNED FOR USE WITH IMPACT TOOLS.
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com OPERATION 1. Locate the socket over the nut to be tightened or loosened. 2. Squeeze the trigger to start the wrench. 3. Release the trigger to stop the wrench. The anvil will continue to rotate briefly after the trigger has been released. NOTE: Where the torque setting is critical, the final tightening must be by hand using a correctly calibrated torque wrench. LOOSENING A WHEEL NUT/BOLT 1. Remove any wheel trim, before se lecting the appropriate socket and placing firmly on the square drive of the wrench. 2. With the control switch in the REVERS E running position (anti-clockwise) and holding the wrench firmly in BOTH HANDS, squeeze the trigger. The nut will be impacted repeatedly until it is loosened. IMPORTANT! Release the trigger as soon as 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 fully undo the wheel nuts. 4. Soak rusted nuts in penetrating oil, and break any rust seal before twisting off with the wrench. TIGHTENING A NUT 1. Start the nut/bolt by hand, ensuring it is not cross threaded, then with the appropriate socket installed on the wrench, place it on the nut/bolt. 2. With the selector switch in the cloc kwise (forward running) position and holding the wrench firmly in BOTH HANDS, squeeze the trigger. 3. Run each nut/bolt up in turn until it is ‘nipped’ up only - do not tighten. When all nuts/bolts are nipped up, tighten progressively by squeezing the WARNING: WAIT UNTIL THE WRENCH HAS STOPPED ROTATING BEFORE OPERATING THE FORWARD/REVERSE SWITCH. WARNING: ENSURE THAT THE CORRECT SOCKET IS BEING USED FOR THE NUTS/BOLTS ON YOUR PARTICULAR VEHICLE. USING AN INCORRECT SOCKET SIZE IS LIKELY TO DAMAGE THE HEADS OF THE BOLTS/NUTS.
Parts & Service: 020 8988 7400 / E-mail: Parts@clarkeinternational.com or Service@clarkeinternational.com trigger fully and allowing the action to operate briefly to prevent overtightening. 4. ALWAYS finish tightening nuts and bolts 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/bolts are tightened. Ensure the final torque applied to the nuts/bolts meets the vehicle manufacturer’s recommendations. 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. MAINTENANCE DAILY 1. Before use, drain water from th e airline filter and compressor. 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. After this you can operate the tool. 3. This procedure should be repeated after every two to three hours of use, or at the start of the working day. WARNING: MAKE SURE THAT THE WRENCH IS DISCONNECTED FROM THE AIR SUPPLY BEFORE STARTING ANY CLEANING OR MAINTENANCE PROCEDURES.

Check the air inlet screen filter and exhaust vent for blockage and clean out if necessary. CLEANING & OVERHAUL 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 beco mes 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. 4. The air tool may be dismantled by unfastening the bolts and removing the rear cover prior to replacing any worn or damaged parts. 5. While is a dismantl ed state, it will be desirable to grease the hammer mechanism with a small amount of good quality bearing grease. This may be better left to your CLARKE dealer.
