return to the 'Off' position when released.

-Always shut off the air supply to the tool and press the 'OntOff'valve to exhaust the air from the feed hose before fitting, removing or adjusting the working attachment fitted to the tool.

-Before using the tool, make sure that a shut off device has been fitted to the air supply line and the positionis 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 or parts of the body to be drawn towards and in contact with the moving parts of the tool and could be very dangerous.

-It is expected that users will adopt safe working practices and observe all local, regional and country legal r e q u i r e m e n t s when installing, using or maintaining the tool.

-Take care that the exhaust air does not point towards any other person or material or substance that could be contaminated by oil droplets. When first lubricating a tool or if the tool exhaust has a high oil content, do not allow the exhaust air to come near very hot surfaces or flames.

N e v e r lay the tool down until the working attachment

has stopped moving.

-When the tool is no?in use, shut off the air supply and press the triggerflever to drain the supply line. If the toot 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.

-I f the tool is passed from one user to a new or inexperienced user, make sure these instructions are 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 workplace with clamps, a vise, etc. to make it rigid so it does not move during the work operation. Keep good balance at all times.

Do not stretch or overreach.

-Try to match the too! to the work operation. Do not use a tool that is too light or heavy for the work operation. If in doubt, seek advice.

-i n general terms, this too! is not suitable for

underwater use or use in explosive environments - seek advice from manufacturer.

-Tryto make sure that the work area is dear to enable the work task to be performedsafely. If practical and

possible, try to clear unnecessary obstructionsbefore

starting work.

-Alwaysuse air hose and couplings with minimum working pressure ratings at least 1 112 times the maximum working pressure rating of the tool.

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

-to avoid the oossibilitv of hand/arm/bodventrapment.

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

There is no consistent. reliable torque adjustment on an impact wrenchof thistype. However, the air regulatorcan be used to adjust torqueto theapproximatetightnessof a known threadedjoint.Toset the toolto the desired torque, select a nut or screw of known

For additionalpower neededon disassembly work, turn regulator to its fully open position. This impact wrencti is rated a 3/8" bolt size. Rating must be downgraded far spring U bolts, tie bolts, long cap screws, double depth nuts, badly rusted conditions and spring fastenersas they absorb much of the impact power. When possible, clamp or wedge thebolt to preventspringback.

Soak rusted nuts in penetrating oil and break rust seal before removingwith impactwrench. tf mt doesrat start to move inthree to five seconds use a larger size impact wrench. Do not use impact wrench beyond ratedcapacity asthis will drastically reducetool life. NOTE: Actual torque on a fastener is directly related to joint hardness, tool speed, condition of socket and the time me tool is allowed to impact.
