PSV 6 2 bar rating The output of the impact tool in prime working condition is governed by mainly three factors a the input air pressure _ b the time the impact tool is operated on the joint Normal time for joints of average tension requirement 3 to 5 seconds c the setting of the air regulator for a given joint at a given pressure operated for a given time i The alr regulator 14 can be used to regulate the output of the impact tool if no other means of control is available It is strongly recommended that an external pressure regulator ideally as part of a filter regulatorAubricator FAL is used to control air intet pressure 80 that the pressure can be set to help contro the tension required to be applied to the threaded fastener joint There is no consistent reliable torque adjustment on an Impact tool of thls type However the air regulator can be used to adjust torque to the approximate tightness of a known threaded joint To set the too to the desired torque select a nut or screw of known tightness of the same size thread pitch and thread condition as those on the job Turn air regulator to tow position apply tool to nut and gradually Increase power turn regulator to admit more air until nut moves slightly in the direction it was originally set The tool is now set to duplicate that tightness note regulator setting for future use When tightening nuts not requiring critical torque values tun nut up flu
