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 1/2"
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 a teaspoonful (5ml) of a suitable pneumatic motor
lubricating oil preferably incorporating a rust inhibitor. Reconnect tool to
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 oth-
er positions but before any such use, the opera-
tor must be in a secure position having a firm
grip and footing and be aware that when loos-
ening fasteners the tool can move quite quickly
away from the fastener being undone. An al-
lowance must always be made for this rear-
ward movement so as to avoid the possibility of
hand/arm/body entrapment.
