parts repaired before using the pneumatic tool. Many accidents are
caused by poorly maintained pneumatic tools.
Use the pneumatic tool, accessories, application tools, etc. accord-
ing to these instructions. Take into consideration the working con-
ditions and the activities to be carried out. Use of the pneumatic tool
for operations different from those intended could result in hazardous
situations.
Service
Have your pneumatic tool repaired only through a qualified repair
person and only using original replacement parts. This will ensure
that the safety of the pneumatic tool is maintained.
Safety Warnings for Compressed-air Nailers/Staplers
Wear safety goggles.
Always assume that the pneumatic tool is loaded with fasteners.
Careless handling of the pneumatic tool can lead to unexpected shot
actuation of fasteners and cause injury.
When working, hold the pneumatic tool in such a manner that your
head and body cannot be injured in case of sudden kickback due to
a malfunction of the energy supply or from hard objects/locations
in the workpiece.
Never point the pneumatic tool at yourself or at persons close by.
Unexpected actuation will expel a fastener, which can lead to injury.
Do not actuate the pneumatic tool until firmly placed against the
workpiece. When the pneumatic tool is not in contact with the work-
piece, the fastener can bounce away from the fastening point and over-
load the pneumatic tool.
Do not work on ladders or scaffolds when the actuation
system "Contact actuation" is set. In particular, do not
move from one fastening location to another, close
boxes or enclosures, or fasten transport-securing fix-
tures on e.g., vehicles and waggons, via scaffolds,
stairs, ladders or ladder-like constructions, such as
roof battens. With this actuation system, a fastener will be
discharged each time when accidentally applying the
pneumatic tool while the discharge lock-off is pressed in.
This can lead to injury.
Observe the conditions of the job site. It is possible that fasteners
can burst through thin workpieces or be deflected when working in cor-
ners or against edges, and harm persons.
Disconnect the air supply, when the fastener is
jammed in the pneumatic tool. When the pneumatic tool
is still connected to the power supply, it can accidentally
be actuated when removing a jammed fastener.
Use caution when removing a jammed or stuck fastener. The sys-
tem can be under tension and cause the fastener to be shot or thrust
out, while attempting to clear the jam.
Do not use this to pneumatic tool to fasten electrical wiring. It is not
suitable for fastening electrical wiring, can damage the insulation of
electric cables and thus lead to electric shock and danger of fire.
Never use oxygen or flammable gases as the energy source for the
pneumatic tool. Flammable gases are dangerous and can cause the
pneumatic tool to explode.
1 609 929 Y30 | (25.3.11)
Use appropriate detectors to determine if utility lines are hidden in
the work area or call the local utility company for assistance. Con-
tact with electric lines can lead to fire and electric shock. Damaging a
gas line can lead to explosion. Penetrating a water line causes property
damage or may cause an electric shock.
The pneumatic tool may only be connected to lines, for which the
maximal permissible pressure of the pneumatic tool cannot be ex-
ceeded by more than 10 %; for higher pressures, a pressure con-
trol valve (pressure reducer) with preceding pressure-limitation
valve in the compressed-air line must be installed. Excessive pres-
sure leads to abnormal operation or breakage of the pneumatic tool,
which can lead to injury.
