Spark Plug; Air Filter; Cleaning The Air Filter - Husqvarna 325HE3 Manuel D'utilisation

The cooling system consists of:
1 Air intake on the starter.
2 Fins on the flywheel.
3 Cooling fins on the cylinder.
4 Cylinder cover (directs cold air over the cylinder).
Clean the cooling system with a brush once a week, more
often in demanding conditions. A dirty or blocked cooling
system results in the machine overheating which causes
damage to the piston and cylinder.

Spark plug

The spark plug condition is influenced by:
• Incorrect carburetor adjustment.
• An incorrect fuel mixture (too much or incorrect type
of oil).
• A dirty air filter.
These factors cause deposits on the spark plug
electrodes, which may result in operating problems and
starting difficulties.
If the machine is low on power, difficult to start or runs
poorly at idle speed: always check the spark plug first
before taking any further action. If the spark plug is dirty,
clean it and check that the electrode gap is 0.026 inch
(0.65 mm). The spark plug should be replaced after about
a month in operation or earlier if necessary.
0,65
CAUTION! Always use the recommended spark plug
type! Use of the wrong spark plug can damage the piston/
cylinder. Check that the spark plug is fitted with a
suppressor.

MAINTENANCE
Air filter
The air filter must be regularly cleaned to remove dust
and dirt in order to avoid:
• Carburettor malfunctions.
• Starting problems.
• Loss of engine power.
• Unnecessary wear to engine parts
• Excessive fuel consumption.
Clean the filter every 25 hours, or more regularly if
conditions are exceptionally dusty.
Cleaning the air filter
Close the choke valve by moving the choke control up.
Remove the air filter cover and take out the filter. Wash it
clean in warm, soapy water. Ensure that the filter is dry
before refitting it.
An air filter that has been in use for a long time cannot be
cleaned completely. The filter must therefore be replaced
with a new one at regular intervals. A damaged air filter
must always be replaced.
If the machine is used in dusty conditions the air filter
should be soaked in oil. See instructions under the
heading Oiling the air filter.
