pieces or slip off corners and edges of workplaces, and thus put people at risk.
For personal safety, use protective equipment such ad hearing and eye
protection (see fig 2)
IMPORTANT: DO NOT direct the adjustable vent hole to the operator or other
person or animals during the use.
2.6 Triggering devices
Fastener driving tools are operated by actuating the trigger using finger pressure.
In addition, fastener driving tool is fitted with a safety yoke which enables the driving
operation to be carried out only after the muzzle of the tool is pressed against a work
piece, These tool are marked with an inverted triangle(
) behind the serial number
and are not permitted for use without an effective safety yoke.
2.7 Actuating systems
Depending on their purpose, fastener driving tool is fitted with actuating system of
single sequential actuation and contact actuation.
You could switch to one nail figure to choose single sequential actuation, and switch
to two nail figure to choose contact actuation.
- Single sequential actuation: An actuating system in which the trigger and the safety
yoke have to be activated so the only one single driving operation is actuated via the
trigger after the muzzle of the tool has been applied to the driving location,
Thereafter further driving operations can only be performed after the trigger has
been returned to the non driving position whilst the safety yoke remains depressed.
-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 order of
actuation not being specified .For repeated 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 actuation must be marked with the
symbol" Do not use on scaffoldings, ladders' (see Fig.4) and shall not be used for
specific application for example:
- when changing one driving location to another involves the use of scaffoldings,
stairs, ladders, or ladder alike constructions, e.g. roof laths;
