Stihl FS 45 Manual

Warning! Exercise extreme
caution when carrying out
maintenance and repair work on
the ignition system. The high
voltages which occur can cause
serious or even fatal accidents!
Troubleshooting on the ignition
system should always begin at
the spark plug. See "Standard
Repairs, Troubleshooting"
handbook.
Note: The electronic (breakerless)
ignition system basically consists
of an ignition module (1) and
flywheel (2).
The ignition module accommoda-
tes all the components required to
control ignition timing.
There are two electrical connec-
tions on the coil body:
1. the high voltage output (1) with
ignition lead (2)
2. the connector tag (3) for the
short circuit wire
Accurate testing of the ignition
module is only possible with
sophisticated test equipment.
For this reason it is only necessary
to carry out a spark test in the
work-shop. A new ignition module
must be installed if no ignition
spark is obtained (after checking
that wiring and stop switch are in
good condition).
Ignition timing is not adjustable.
Since there is no mechanical wear
in these systems, ignition timing
cannot get out of adjustment.
However, an internal fault in the
circuit can alter the switching point
in such a way that a spark test will
stillshowthesystemtobeinorder
although timing is outside the
permissible tolerance. This will
impair engine starting and running
behavior.
