Avoid any weakening and damage whatsoever of the
pneumatic tool, e.g., through:
– Imprinting or engraving,
– Retrofitting measures not approved by the manufactur-
er,
– Guiding along templates manufactured of hard materi-
al, e.g. steel,
– Dropping on or sliding over the floor,
– Using as a hammer,
– Applying any kind of force.
Make sure to check whatever is below or behind your
workpiece. Do not shoot staples (GTK 40) or brads
(GSK 50) into walls, ceilings or floors, when persons are
behind them. The fasteners can burst through the work-
piece and injure someone.
Do not shoot a staple (GTK 40) or brad (GSK 50) on al-
ready driven-in fasteners. This could cause the fastener to
deform, the fasteners could become jammed or the pneu-
matic tool could move uncontrolled.
When the pneumatic tool is used under cold ambient con-
ditions, the first staples (GTK 40) or brads (GSK 50) are
driven in slower than usual. Once the pneumatic tool has
warmed up during working, normal operating speed will
be regained.
Avoid blank shots in order to reduce the wear of the im-
pact striker.
For longer work breaks or after finishing work, discon-
nect the pneumatic tool from the air supply and empty
the magazine.
