1. 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 tum 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 run nut up flush and then tighten an additional one quarter to one half tum slight additional tuming 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 3 8 bolt size Rating must be downgraded for spring U boits tie bolts long cap screws double depth nuts badly rusted conditions and spring fasteners as they absorb much of the impact power When possible clamp or wedge the bolt to prevent springback Soak rusted nuts in penetrating oll and break rust seal before removing with impact wrench if nut does not start to move in three to five seconds use a larger size impact wrench Do not use impact wrench beyond rated capacity as this will drastically reduce tool2. ment fitted to the tool Before using the tool make sure that a shut off device has been fitted to the supply line and the position is known and easily accessible so that the air supply to the tool can be shut off in an emergency Check hose and fittings regularly for wear Take care against entanglement of the moving parts of the tool with clothing hair ties cleaning rags rings jewelry watches bracelets etc This could cause the body pom of border y to be drawn towards contact wi moving parts of the tool and could be very It is expected that users will adopt safe working practices and observe all local regional or country legal Use personal protection equipment as recommended Never lay the tool down until the working attachment has Use compressed air only at the recommended conditions If the tool appears to malfunction remove from use stopped moving When the tool is not in use shut off the air supply and press throttle trigger ever to drain the supply line If the tool is not to be used for a period of time first lubricate disconnect from air supply and store in a dry average room temperature environment If the tool is passed from one user to a new or inexperi enced user make sure these instructions are available to be passed with the tool Do not remove any manufacturer fitted safety devices where fitted i e wheel guards safety trigger speed governors etc Wherever possible secure workpiece

5. To do so may be dangerous i Never use an impact wrench as a hammer to dislodge or straighten cross threaded fasteners Never attempt to modify the tool for other uses and never modify the tool for even its recommended use as a nutrunner Work Stations The too should only be used as a handheld hand operated tool tt is always recommended that the tool is used when standing on a 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 for this rearward movement so as to avoid the possibility of hand amv 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 PSIG 6 2 bar when the tool is running with the trigger ever fully depressed Use recommended hose size and length it is recommended that the tool is connected to the air supply as shown in figure 1 0 not connect the tool to the air line system without incorporating an easy to reach 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 the correct pressure to the tool Details of such equipment can be obtained from your sup
