Important
Read these instruction carefully before installing, operating, servicing or repairing this tool. Keep these instructions in a safe accessible place.

Foreseen Use Of Tool

The impact wrench is designed for the tightening and loosening of threaded fasteners within the rang as specified by manufacturer It should only be used in conjunction with suitable impact type 1 2 13 mm) square female driver nut running sockets Only use sockets which are of the impact type It is allowed to use suitable extension bars, universal joints and socket adaptors between the square output driver of the impact wrench and the square female drive of the socket Do not use the tool for any other purpose than that specified without consulting the manufacturer or the manufacturer’s authorized supplier To do so may be dangerous Never use an impact wrench as 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 nut runner.

Work Stations

The tool should only be used as a handheld hand operated tool. It is always recommended that the tool is used when standing on the solid floor. It can be 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/arm/body entrapment.

Do not connect a quick connect coupling directly to the tool but use a whip or a leader hose of say approximately 12 inches 300 mm) length Do not connect the tool to the airline 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 ( 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 supplier If such equipment is nit used then the tool should be lubricated by shutting off the air supply to the tool, depressurizing the line by pressing the trigger on the tool Disconnect the air line and pour into the intake bushing a teaspoonful 5 mL) 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 screen in intake bushing is clean It is recommended that the air pressure at the tool whilst the tool is running at 90 psi 6 3 bar The tool can run at lower and higher pressure with the maximum permitted working air pressure of 100 psi 7 0 bar For a lower air pressure the tool will give a lower output for a given setting of the sir regulator set for 90 psi 6 3 bar operation and increased output for higher pressure Hence it is possible that changes in supply pressure can give situation where the fastener is under over tightened For changes in pressure, the regulator position and application should be reassessed It is recommended that joint tightness of the threaded fastener assembly be checked with suitable measuring equipment Follow the national legislation of waste disposal.

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.i ./6.3 bar when the tool 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.

Operating

The output of the impact wrench in prime working condition is governed by mainly three factors:

• The input air pressure.
• The time the impact wrench is operated on joint Normal time for joints of average tension requirement 3 to 5 seconds.
• The setting of air regulator for a given joint at a given pressure operated for a given time.

The air regulator can be used to the regulate the output of the impact wrench if no other control means is available. It is strongly recommended that an external pressure regulator ideally as part of a fitter/regulator/lubricator (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 known threaded joint. To set the tool to the desired torque, select an 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 future use. When tightness nuts not requiring critical torque values, run nut up flush 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 bolt size(please refer technical specification of tool). Rating must be down graded 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, clamp or wedge the 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 large size impact wrench. Do not use impact wrench beyond rated capacity as this will drastically reduce tool life.
Note: Actual torque on a fastener is directly related to joint hardness, tool speed, condition of socket and the time the tool is allowed to impact. Use the simplest possible tool=to-socket hook up. Every connection absorbs energy and reduces power.
