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
tool for any other purpose. Do not modify the tool to be used for
any other purpose or for its use as a stapler without first
agreeing any such modifications with the manufacturer or an
authorised distributor.

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 an d run tool slowly for a fe w seconds to allow a ir 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.

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 show n in fig ure 1. Do not
connect the tool to the air line
