caused to the head or to the body in the event of possible recoil consequent upon a disruption in the energy supply or
hard areas within the workplace.（see fig 2）
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 shall be disconnected from the compressed air system for the purpose of transportation, especially where
ladders are used or where an unusual physical posture is adopted whilst moving (see Fig 3).
Carry the fastener driving tool at the workplace using only the handle, and never with the
trigger actuated.
Take conditions at the workplace into account. Fasteners can penetrate thin work 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;
- closing boxes or crates;
- fitting transportation safety systems e.g. on vehicles and wagons.
