Foreseen Use Of The Tool - 5038Bl
50396
The impact wrench is designed for the tighteningand loosening of threaded fasteners within the range as specified by the manufacturer It should only be used 10 conjunction with suitable impact type 318' square female drive nut running sockets. Only use sockets which are of the impact type.
It is allowed to use suitable extension bars. univefsat joints and socket adaptors between the square output drive of the impact wrench and the square female drive oi the socket.
Do not use the tool for any other purpose than that specified without consulting the manufacturer or the manufacturer's authorizedsupplier To do so may tie dangerous,

Work Stations
The toolshould only beused as a handheld, handoperated tool. It is always recommendedthat the tool is usedwhen 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 quickty away from the fastener being undone. An allowance must always be made for this rearwardmovementso as

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.16.2 tsar when the tool is running with the trigger fully depressed and the air regulator in its maximumopeningflow position.Use recommeridedhose size and length. 1; 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 8001, but use a whip or leader hose of approximtely 12 inches length. Do not connect the tool to the air line system without incorporatingan easy to reachand 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, lubricatedairat the 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 40 the tool, depressurizing the line by pressing the ihronle lever on the too). Disconnect the air line and pour into the hose adaptor (9) 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 (9) is clean.
It is recommended that joint tightness of the threaded fastener assembly be checked with suitabie measuring equipment.
It is recommendedthat the air pressurea! the tool while the tool is
-running is 90 p.s.i./6.2 bar.
Operating
The output of the impact wench in prime working condition is governedby mainly three factors:
a)the input air pressure;
b)thetime the impact wrench is operated on the joint. Normal time for joints of averagetension requirement3 to 5 seconds;
c)the selling of the air regulatorfor a given joint at a given pressure
operatedfor a given time.
The air regulator (26) can be used to regulate the output of the impact wench if no other means of control is available. It is strongly
rm m d e d that an externalpressure regulator, ideallyas part of a filter/rqulator/ltibricator(FRL). is usedto control air inlet pressure so that thepressure can be set to help control the tension required to he applied to Ihe threaded fastener joint
