The spark in an electronic ignition system
has a very short burn time and can therefore
be interpreted as weak and can be difficult to
see while trouble shooting.
Deviations:
The cylinder cover is located using four
screws instead of three. (325HS)
325HS:The speed is limited to 11,600
rpm.
325HDA55/325HE:
The speed is limited
to 10,000 rpm.
General
325HS75, 325HS99, 325HE2, 325HE3,
325HE4: See Brushcutter 325.
The thick threaded screw (for the clip
set) should be placed in the hole
closest to the gearbox.
Assembling the cylinder
cover
325HS75, 325HS99:
Check that the ignition cable is in
position in the cut-out in the gearbox.
Align the cylinder cover with the slot for
the screw pin, make sure that when the
cover is moved down that the ignition
cable is secured by the wedge shaped
cut-out in the cylinder cover.
Assembling the cylinder
cover
325HS75, 325HS99:
Fit the cylinder cover.
NOTE!
Risk for incorrect assembly.
The ignition cable can be damaged by
the flywheel if incorrectly routed. The
protective casing on the ignition cable
must be clamped in the securing ear (to
get sufficient length of ignition cable to
the wedge shaped cut-out).
If the wrong screw is placed in the hole
closest to the gearbox the threads in
the clip set will be crossed.
Ignition system
The engine is equipped with an electronic ignition
system completely without moving parts.
Consequently, a faulty component cannot be
repaired, but must be replaced by a new compo-
nent.

3Fuel system
In addition to the fuel tank and carburettor, the
fuel system consists of the air filter, fuel filter and
tank venting.
All these components interact so that the engine
receives the optimal mixture of fuel and air to
make it as efficient as possible.Very small devia-
tions in the carburettor setting or a blocked air
filter have a large effect on the running and
efficiency of the engine.
The carburettor can come from several differ-
ent manufacturers on our models, yet the
function and repair methods are essentially the
same.
