Cooling System; Air Filter; Fuel Filter; Bevel Gear - McCulloch B40 P ELITE Operator's Manual

Cooling system

To keep the working temperature as low as possible the
machine is equipped with a cooling system.
The cooling system consists of:
1 Cooling fins on the cylinder.
2 Air intake.
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.
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
Remove the air filter cover and take out the filter. Blow
clean with compressed air.

MAINTENANCE

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.
Fuel filter
1 Fuel filter
When the engine runs short of fuel supply, check the fuel
cap and the fuel filter for blockage.

Bevel gear

The bevel gear is filled with the right quantity of grease at
the factory. However, before using the machine you
should check that the bevel gear is filled three-quarters
full with grease. Use HUSQVARNA special grease.
The grease in the bevel gear does not normally need to
be changed except if repairs are carried out.

Spark plug

The spark plug condition is influenced by:
• Incorrect carburettor 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.
