Problem
The staples (GTK 40) or brads
(GSK 50) are not driven in deep
enough.
The pneumatic tool skips sta-
ples (GTK 40) or brads
(GSK 50) or has a too large cy-
cle feed.
The staples (GTK 40) or brads
(GSK 50) frequently jam in the
shot duct.
The driven staples (GTK 40) or
brads (GSK 50) are bent.
Contrary to working with nor-
mal operating speed, the sta-
ples (GTK 40) or brads
(GSK 50) are not driven in deep
enough enough at higher oper-
ating speeds.
