Foreseen Use of Tool
This tool is designed for the purpose of driving staples for only
the sizes as indicated in the section “Operating”. Do not use the

any other purpose or for its use as a stapler without first
agreeing any such modifications with the manufacturer or an
authorised distributor.
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. 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 the tool to the air line
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

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
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.
It is recommended that the air pressure at the tool whilst the
tool is running is 90 p.s.i./6.3 bar. The tool can run at lower and
higher pressures with the maximum permitted working air
pressure of 100 p.s.i./7.0 bar.

position. The trigger/lever etc. must always be free to return to
the 'off' position when it is released.
12) Always shut off the air supply to the tool, and depress the
trigger/lever etc. to exhaust air from the feed hose before fitting,
adjusting or removing the working attachment.
13) Check hose and fittings regularly for wear. Replace if
necessary. Do not carry the tool by its hose and ensure the hand
is remote from the on/off control when carrying the tool with
the air supply connected.
14) Take care against entanglement of moving parts of the tool
with clothing, ties, hair, cleaning rags, etc. This will cause the
