It is always recommended that the tool is used when standing on the solid floor. It can be used in other positions, but before any such use, the operator must be in a secure position having a firm grip and footing and be aware that when loosening fasteners the tool can move quite quickly away from the fastener being undone. An allowance must always be made lor this rearward movement so as to avoid the possibility of handferm/body entrapment. Putting Into Service Air Supply Use a clean lubricated air supply that will give a measured air pressure at the tool of 90 p.s.iJ6.2 bar when the tod is running with the trigger fully depressed and the air regulator in its maximum opening flow position. Use recommended hose size and length. It is recommended that the tool is connected to the air supply as shown in figure 1. Do not connect a quick connect coupling directly to the tool, but use a whip or leader hose of approximately 12 inches length. Do not connect the cool to the air line system without incorporating an easy to teach and operate air shut off valve. The air supply should be lubricated. It is strongly recommended that an air filter, regulator, lubricator (FRL) is used, as shown in Figure 1, as this will supply clean, lubricated air at (he correct pressure to the tool. Details of such equipment can be obtained from your supplier. If such equipment is not used, then the tool should be lubricated by shutting off the air supply to the tool, depressurizing the line by pressing the throttle lever on the tool. Disconnect the air line and pour into the hose adaptor (16) a teaspoonful (5ml) of a suitable pneumatic motor lubricating oil preferably incorporating a rust inhibitor. Reconnect tool to air supply and run tool slowly for a few seconds to allow air to circulate the oil. If tool is used frequently, lubricate on daily basis and if tool starts to slow or lose power. When lubricating, also ensure that the air strainer in hose adaptor (16) is clean. It is recommended that joint tightness of the threaded fastener assembly be checked with suitable measuring equipment. It is recommended that the air pressure at the tool while (he tool is running is 90 p.s.i./6.2 bar. Operating The output ol the impact wrench in prime working condition is governed by mainly three factors: a) the input air pressure; b) the time the impact wrench 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. The air regulator (20) can be used to regulate the output of the impact wrench if no other means of control is available, tt is strongly recommended that an external pressure regulator, ideally as part of a filter/regulatorflubricator (FRL). is used to control air inlet pressure so that the pressure can be set to help control the tension required to be applied to the threaded fastener joint. There is no consistent, reliable torque adjustment on an impact wrench of this type. However, the air regulator can be used to adjust torque to the approximate tightness of a known threaded joint. To set the tool 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 low position, apply wrench 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 iuture use. When tightening nuts not requiring critical torque values, run nut up Hush and then tighten an additional one-quarter to one-half turn (slight additional turning is necessary if gaskets are being clamped). For additional power needed on disassembly work, turn regulator to its fully open position. This impact wrench is rated a 1/2’ bolt size. Rating must be downgraded for spring U bolts, tie bolts, long cap screws, double depth nuts, badly rusted conditions and spring fasteners as they absorb much of the impact power. When possible, damp or wedge tt» bolt to prevent spring back. Soak rusted nuts in penetrating oil and break rust seal before removing with impact wrench. If nut does not start to move in three to • five seconds use a larger si2e impact wrench. Do not use impact wrench beyond rated capacity as this w3l drastically reduce tool fife. NOTE: Actual torque on a fastener is directly related to joint hardness, tool speed, condition of socket and the time the tool is a flowed to impart. Page No 2 Use the simplest possible tooMo-socket hook up. Every connection absorbs energy and reduces power. The forward and reverse control and the air regulator on this tool are combined into a single feature and operated by air regulator/reverse valve knob (20), This knob can be rotated to give 3 speed/power outputs (position 3 being the highest output position) and a single full power in reverse...
