Foreseen Use Of Tool

The impact wrench is designed for the tightening and loosening of
threaded fasteners within the range as specified by the manufacturer.
It should only be used in conjunction with suitable impact type 1"
square female drive 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 drive 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 authorised
supplier. To do so may be dangerous.
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 tool should only be used as a handheld
hand operated tool. It is always recom-
mended 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.

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. Do
not connect a quick connect coupling directly to the tool but use a
whip or leader hose of say approximately 12 inches length. Do 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 supplier. If such equipment is
not used then the tool should be lubricated by shutting off the air
supply to the tool, depressurising the line by pressing the trigger on
the tool. Disconnect the air line and pour into the intake bushing a
teaspoonful (5ml) of a suitable pneumatic motor lubricating oil
