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.
