Fault Analysis: STIHL Engine Check
When a unit is running poorly or not at all, using a systematic
approach to identify any and all faults present will allow the
Service Technician to quickly and efficiently determine what is
wrong
It is just as
important to
know what
faults are not
present as well
as faults that
do need to be
addressed

DG Screws
It is imperative that the Service Technician keep track of which
screw is which and not screw them into the wrong base
material or the threads will be damaged
It is also best practice that when starting a DG screw into the
hole, slowly rotate it backwards until it “clicks” to index the
threads, then turn it clockwise to tighten it
For Plastic
For Metal
STIHL uses the DG type of
fastener in manufacturing because
they cut their own threads the first
time they are used
Notice that the ones holding into
plastic have a different pitch and
profile than the ones that hold into
metal
