caused to the head or to the body in the event of
a possible recoil following a disruption in the en-
ergy supply or hard areas within the workpiece.
Make sure there are no nail heads or other hard
objects at the penetration spot.
–
Never actuate the fastener driving tool into free
space. This will avoid any hazard caused by free
flying fasteners and excessive strain of the tool.
–
The tool must be disconnected from the com-
pressed air system for the purpose of transporta-
tion, especially where ladders are used or where
an unusual physical posture is adopted whilst
moving.
–
Carry the fastener driving tool at the workplace
using only the handgrip, and never with the trig-
ger actuated.
–
Take conditions at the workplace into account.
Fasteners can penetrate thin work-
pieces or slip off corners and edges
of workpieces, and thus put people
at risk.
–
Use protective equipment such as
ear and eye protection.
1.6 TRIGGERING DEVICES
This fastener driving tool is operated by actuating the
trigger using fi nger pressure.
Some fastener driving tools are fitted with an addi-
tional safety yoke which enables the driving oper-
ation to be carried out only after the muzzle of the
tool is pressed against a workpiece. These tools are
marked with an inverted triangle (
8
) and may not be
used unless fitted with an effective safety yoke.
1.7 ACTUATING SYSTEMS
Depending on their purpose, fastener driving tools
may be fitted with different actuating systems. See
the respective technical data sheet for details of the
actuating system of the tools.
Single sequential actuation (preferred version)
: An
actuating system in which the safety yoke and the
trigger have to be activated in such a way that one
single driving operation is actuated via the trigger
after the muzzle of the tool has been applied to the
driving location. Thereafter any further driving oper-
ations can only be actuated after the trigger has been
returned to the starting position.
Full sequential actuation:
This is an actuating system
in which the safety yoke and the trigger have to be
activated in such a way that one single driving opera-
tion is actuated via the trigger after the muzzle of the
tool has been applied to the driving location. There-
after any further driving operations can only be actu-
ated only after the trigger and the safety yoke have
been returned to the starting position.
Contact actuation (restricted version):
An actuating
system in which the trigger and the safety yoke have
to be actuated for each driving operation, with the or-
der of actuation not being specifi ed. For subsequent
driving operations it is sufficient if either the trigger
remains activated and the safety yoke is activated
thereafter, or vice versa.
Fastener driving tools equipped with contact actua-
tion must be marked with the symbol »Do not use on
scaffoldings, ladders« and must not be used for spe-
cific applications for example:
–
when moving from one driving location to an-
other involves the use of scaffoldings, stairs, lad-
ders, or ladder-like constructions,
e.g. roof laths,
–
closing boxes or crates,
– fitting transportation safety sys-
tems e.g. on vehicles and wagons.
Single sequential actuation with trigger lock:
Some
models have a safety system consisting of a small le-
ver attached behind the trigger which blocks automat-
ically every time the trigger is released, preventing
unintentional triggering. If a fastener is to be driven,
the safety lever must be pulled first, which enables
the main trigger and makes it possible to press.

tools
