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 3/4" 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.
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 hose adaptor (7) a teaspoonful (5ml) of a suitable
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.
