ENGLISH
24
• Don’t use the tool for attaching transportation
safety devices e.g. on vehicles and carriages.
• Before use check proper function of contact
trip. Never use this tool when either trigger
switch or contact trip is damaged.
• Use quick-action couplings for connection to
the compressed air system. The non-sealable
nipple must be fitted to the tool in such a way
that no compressed air remains in the tool after
disconnection.
• ALWAYS use clean, dry compressed air. Do not
use oxygen or combustible gases as an energy
source for this tool.
• The maximum allowable air pressure of the tool
shall NEVER be exceeded.
• Only connect this tool to an air supply where
the maximum allowable pressure of the tool
cannot be exceeded by more than 10%. In case
of higher pressures, a pressure reducing valve
including a downstream safety valve shall be
built into the compressed air supply.
• Only use hoses with a rating exceeding the
maximum operating pressure of the tool.
• To prevent an unnecessarily high noise level,
increased wear and resulting failures, the nailer
should be operated with the lowest pressure
required for the work process.
• DO NOT use oxygen, combustible gases
or any other reactive gases for operating
compressed air. Danger of explosion and/or
serious personal injury may result.
• Before transporting the tool, disconnect it from
the compressed air system, especially where
ladders are used or where unusual physical
posture is adopted while moving.
• Disconnect the tool from the air supply when it
is not in use.
• Avoid weakening or damaging the tool,
for example by:
– punching or engraving
– modifications not authorised by the
manufacturer
– guiding against templates made of hard
material such as steel
– dropping or pushing across the floor
– applying excessive force of any kind
• Do not use the equipment as a hammer.
WARNING! Keep the nailer, loaded or
unloaded, pointed away from yourself and
others. Serious personal injury may result.
• While working, hold the tool in such a way that
no injuries can be caused to the head or to the
body in the event of a possible recoil due to a
disruption in the energy supply or hard areas
within the workpiece.
• NEVER actuate the fastener driving tool into
free space.
• In the work area, carry the tool at the workplace
using only one handle, and NEVER with the
trigger actuated.
• Consider the conditions in the work area.
Fasteners can penetrate thin workpieces or slip
off corners and edges of the workpiece, and
thus put people at risk. The length of the nails
used should be no longer than the thickness of
the workpieces. If the nails are longer than the
workpiece thickness this could cause a rebound
of the nails if the workpiece is placed on a hard
surface e.g., concrete, steel.
• Do not drive fasteners close to the edge of the
workpiece. ALWAYS keep a distance of at least
25 mm from the edge of the workpiece so nails
will not destroy the workpiece.
• Do not drive fasteners on top of other fasteners.
• Only use spare parts specified by the
manufacturer or his authorised agents.
• Have repairs carried out only by the
manufacturer or authorised agents having due
regard to the information given in the manual
and using the appropriate tools and equipment.
• Replacement of contact trip spring is
recommended every 3–4 years to ensure
personal safety.
• Do not disassemble or block any parts of the
fastener driving tool such as the safety yoke.
• Have the tool serviced properly and at regular
intervals.
• ALWAYS wear safety gloves to reduce the risk
of personal injuries.
Residual Risks
• The following risks are inherent to the use of
these machines:
– Injuries caused by improper handling of
the tool.
– Loss of control due to not grippring tool
firmly.
– Muscle strain of arms and hands,
especially when working overhead.
Always take regular breaks when
working for long periods of time.
