manual abstract
There is an increased risk of electric shock if your body is grounded. • Thoroughly investigate the workpiece for possible hidden wiring before performing work. HAZARD RISK OF ENTANGLEMENT WHAT COULD HAPPEN HOW TO PREVENT IT • Tools which contain moving elements, or drive other moving tools, such as grinding wheels, sockets, sanding discs, etc. can become entangled in hair, clothing, jewelry and other loose objects, resulting in severe injury. • Never wear loose fitting clothes, or apparel which contains loose straps or ties, etc. which could become entangled in moving parts of the tool. • Remove any jewelry, watches, identifications, bracelets, necklaces, etc. which might become caught by the tool. • Keep hands away from moving parts. Tie up or cover long hair. • Always wear proper fitting clothing and other safety equipment when using this tool. HAZARD RISK OF CUT OR BURNS WHAT COULD HAPPEN HOW TO PREVENT IT • Tools which cut, shear, drill, staple, punch, chisel, etc. are capable of causing serious injury. • Keep the working part of the tool away from hands and body. D22725 4- ENG SPECIFICATIONS Maximum Torque 400 ft./lbs. Blows Per Minute 1000 Free Speed RPM @ 90 PSI 7000 Maximum Working Pressure 90 PSI Air Inlet 1/4” NPT Recommended Hose Size 3/8” I.D. Air Consumption @ 90 PSI 4.2 SCFM ASSEMBLY Accessories Required IMPORTANT: Line pressure or hose inside diameter should be increased to compensate for unusually long air hoses (over 25 feet). Minimum hose diameter should be 3/8” I.D. and fittings should have 1/4” NPT thread. OPERATION Operation Before each use: . Drain water from air compressor tank and condensation from air lines. See air compressor’s operators manual. Disconnect the tool from the air supply before lubricating or changing sockets. . Lubricate tool, see “Maintenance” section in this manual. Impact wrench sockets and accessories must be used with this tool. Do not use hand sockets and accessories. . Select the required impact socket. This tool has a 1/2" square drive, use 1/2” deep sockets. Use 1/2” extensions only when needed. . Connect tool to air hose of recommended size. NOTE: The use of a quick connect set makes connecting easier. See the “Accessories” section of this manual. IMPORTANT: The use of air filters and air line lubricators is recommended. To use: . Turn air compressor on and allow air tank to fill. . Set the air compressor’s regulator to 90 PSI. This tool operates at a maximum 90 PSI pressure. . Set torque regulator, see chart, to set the desired setting to avoid over tightening. IMPORTANT: These torque values can vary depending on the size of the air compressor and the cubic feet of air (SCFM) the air compressor delivers. Line up desired torque # with raised pin #1 approximately 190-250 ft./lbs. Torque #2 approximately 250-300 ft./lbs. Torque #3 approximately 300-350 ft./lbs. Torque #4 approximately 350-400 ft./lbs. Torque 5- ENG D22725 . Place tool in forward or reverse position. Push button in on “F” side for forward or “R” side for reverse. Push button all the way in on the “F” side for Forward position. Push button all the way in on the “R” side for Reverse position. . Depress the trigger to operate tool. . Release trigger to stop tool. . Always disconnect air supply when changing sockets. . When job is complete, turn the air compressor off and store as described in the air compressor operator manual. MAINTENANCE Lubrication Air tools require lubrication throughout the life of the tool. The air motor and bearing uses compressed air to power the tool. Because moisture in compressed air will rust the air motor, you must lubricate the motor daily. An inline oiler is recommended. To lubricate the air motor manually: 1. Disconnect the tool from the air supply holding it so the air inlet faces up. 2. Depress the trigger and place one to two drops of air tool oil in the air inlet Depressing the trigger helps circulate oil in the motor. NOTE: Use SAE #10 weight oil if air tool oil is not available. 3. Connect the tool to an air source, cover the exhaust end with a towel and run for a few seconds. Any excess oil in the motor is immediately expelled from the exhaust port. Always direct exhaust port away from people or objects. Failure to lubricate the tool at the air inlet will void your warranty.
