COMPRESSED AIR REQUIREMENTS 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. • Air compressors used with the tool must comply with the appropriate European Community Safety Directives. • A build-up of moisture or oil in the air compressor will accelerate wear and corrosion in the tool.
BEFORE 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. NOTE: Ensure the compressor is turned off. 1. If required, connect an in-line mini oiler to the tool. • A mini oiler helps to prolong the life of the impact wrench. 2. If a mini-oiler is not being used, run a few drops of oil through the tool before use.
OPERATION WARNING: WAIT UNTIL THE ANVIL HAS STOPPED ROTATING BEFORE OPERATING THE FORWARD/REVERSE BUTTON. Forward/Reverse rotation is selected by pushing the combined Forward/ Reverse knob/power regulator in the direction shown by the arrow on the back of the wrench. 1. For normal tightening, the wrench should be operated in the forward (F) direction. 2. For loosening, the wrench should be operated in the reverse (R) direction. FITTING THE IMPACT SOCKET WARNING: NEVER USE STANDARD SOCKETS.
OPERATING THE IMPACT WRENCH 1. Locate the socket over the nut to be tightened or loosened. 2. Squeeze the trigger to start the wrench. 3. Release the trigger switch to stop the wrench. • The square drive shaft will continue to rotate very briefly after the trigger has been released. ADJUSTING THE POWER 1. To adjust the power, set the air regulator to one of the 3 settings available. (Setting 1-Low, 3 -High) • These numbers are only for reference and do not denote a specific amount of power.
MAINTENANCE WARNING: MAKE SURE THAT THE AIR TOOL IS DISCONNECTED FROM THE AIR SUPPLY BEFORE STARTING ANY CLEANING, OR MAINTENANCE PROCEDURES. DAILY 1. Before use, drain water from the airline filter and compressor. 2. Pour a few drops of Clarke air-line oil, into the tool air inlet. This should be carried out regardless of whether or not an in-line mini oiler is used. If an inline mini oiler is not used, this procedure should be repeated after every two to three hours of use. 3.
TROUBLESHOOTING SYMPTOM PROBLEM SOLUTION Tool runs at normal speed but slows down under any load. 1. Motor parts worn. Tool runs slowly. Air flows weakly from exhaust. 1. Motor parts jammed with gum/dirt. 2. Air-line regulator in closed position. 3. General airflow blocked by dirt. 1. Examine inlet air filter for blockage. Drip a few drops of air tool lubricating oil into air inlet. 2. Adjust in-line regulator to open position. 3. Operate tool in short bursts. Tool will not run.
