COMPRESSED AIR SYSTEM
WARNING! Never free-fire the tool while it is connected to the air supply.
-
Proper functioning of the fastener driving tool requires filtered, dry and lubricated compressed
air in adequate quantities.
-
If the air pressure in the line system exceeds the maximum allowable of the fastener driving
tool, a pressure reducing valve followed by a downstream safety valve shall additionally be fit-
ted in the supply line to the tool.
-
NOTE! When compressed air is generated by compressors, the natural moisture in the air con-
denses and collects as condensed water in pressure vessels and pipelines. This condensate must
be removed by water separators. These water separators must be checked on a daily basis and if
necessary drained, since corrosion can otherwise develop in the compressed air system and in
the fastener driving tool which serves to accelerate wear.
-
The compressor plant shall be adequately dimensioned in terms of pressure output and perfor-
mance for the consumption which is to be expected. Line sections which are too small in rela-
tion to the length of the line (pipes and hoses) as well as overloading the compressor will result
in pressure drops.
-
Permanently laid compressed air pipelines should have an internal diameter of at least 19 mm
and a corresponding large diameter where relatively long pipelines or multiple users are in-
volved.
-
Compressed air pipelines should be laid so as to form a gradient (highest point in the direction
to the compressor). Easily accessible water separators should be installed at the lowest points.
-
Junctions for users should be joined to the pipelines from above.
-
Connecting points for fastener driving tools should be fitted with a compressed air servicing
unit (filter/water separator/oiler) directly at the junction point.
-
Oilers must be checked on a daily basis and if necessary topped up with recommended oil.
Where hose lengths of over 10 m are used, the oil supply for the fastener driving tool cannot be
guaranteed. We therefore recommend that 2 to 6 drops (depending on the loading of the fastener
driving tool) of recommended oil should be added via the air inlet of the tool or an oiler attached
directly to the fastener driving tool.
CONNECTION TO THE COMPRESSED AIR SYSTEM
-
Ensure that the pressure supplied by the compressed air system does not exceed the maximum
allowable pressure of the fastener driving tool. Set the air pressure initially to the lower value of
the recommended allowable pressure (see TECHNICAL DATA).
-
Empty the magazine to prevent a fastener from being ejected unintentionally in the event that
internal parts of the fastener driving tool are not in the starting position following maintenance
or repair work or transportation.
-
Connect the fastener driving tool to the compressed air supply using suitable pressure hose
equipped with quick-action connectors.
