2. COMPRESSED AIR SYSTEM
Proper functioning of the fastener driving tool requires fil-
tered, dry and oiled compressed air in adequate quanti-
ties.
If the air pressure in the line system exceeds the maxi-
mum permissible operating pressure of the fastener driv-
ing tool, a pressure reducing valve followed by a
downstream safety valve shall additionally be fitted in the
supply line to the tool.
Note: When compressed air is generated by compres-
sors, the natural moisture in the air condenses and col-
lects 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 drained if necessary, 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 performance (volumetric
flow) for the consumption which is to be expected. Line
sections which are too small in relation 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 least 19 mm (0.75 inch) and a
correspondingly larger diameter where relatively long
pipelines or multiple users are involved. Compressed air
pipelines should be laid so as to form a gradient (highest
point in the direction to the compressor). Easily accessi-
ble 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 fit-
ted with a compressed air servicing unit (filter/ water sep-
arator/ lubricator) directly at the junction point.
Lubricators must be checked on a daily basis and topped
up with the recommended grade of oil(see technical
data) if necessary. Adjust the lubricator of the mainte-
nance unit to 1 drop for approx. every 15 blows of the fas-
tener. Check the oil level in the reservoir regularly.
Where hose lengths of over 10 m (33 ft) are used, the oil
supply for the fastener driving tool cannot be guaranteed.
We therefore recommend an lubricator attached directly
to the fastener driving tool. Adjust the dosing so that it
has to be refilled approximately every 30 000 blows.
3. PREPARING THE TOOL FOR USE
3.1 PREPARING A TOOL FOR FIRST TIME
OPERATION
Please read and observe these operating instructions
before using the tool. Basic safety measures should
always be strictly followed to protect against damage to
the equipment and personal injury to the user or other
people working in the vicinity of operation.
3.2 CONNECTION TO THE COMPRESSED AIR
SYSTEM
Ensure that the pressure supplied by the compressed air
system does not exceed the maximum permissible oper-
ating pressure of the fastener driving tool. Set the air
pressure initially to the lower value of the recommended
operating pressure (see technical data). Empty the mag-
azine to prevent a fastener from being ejected at the next
stage of work in the event that internal parts of the fas-
tener driving tool are not in the starting position following
maintenance and repair work or transportation.
Connect the fastener driving tool to the compressed air
supply using suitable pressure hose equipped with quick-
action connectors.
Refer to the technical data sheet for the size of plug-in
nipple.
3.3 FILLING THE MAGAZINE
Only those fasteners specified under technical data (see
2) may be used.
When filling the magazine, hold the tool so that the muz-
zle is not pointing towards your own body or towards any
other person. Do not load the tool with fasteners with the
safety yoke or trigger depressed. Further design-related
specifications such as the fastener insertion or removal
as well as filling can be found in the technical data sheet.
3.4 HANDLING THE TOOL
Note section 1. Special references of these operating
instructions.
Having checked that the fastener driving tool is function-
ing correctly, apply the tool to a workpiece and actuate
the trigger.
You should endeavour in any event to work with the low-
est possible air pressure. This will give you three signifi
cant advantages:
1.
energy will be saved,
2. less noise will be produced,
3. a reduction in fastener driving tool wear will be
achieved.
