Spark Plug; Lubricating The Bar Tip Sprocket; Needle Bearing Lubrication; Adjustment Of The Oil Pump - Husqvarna 365 SPECIAL Operator's Manual

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 0.5 mm
(0,020"). The spark plug should be replaced after about a
month in operation or earlier if necessary.
Note! 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.

Needle bearing lubrication

The clutch drum has a needle bearing on the output shaft.
This needle bearing must be lubricated regularly (once a
week). CAUTION! Use only high quality bearing grease or
engine oil. See instructions under the heading Cutting
equipment.

Adjustment of the oil pump

The oil pump is adjustable. Adjustments are made by
turning the screw using a screwdriver or combination
spanner. The machine is supplied from the factory set to
1 turn open. Turning the screw clockwise will reduce the

oil flow and turning the screw anti-clockwise will increase
the oil flow.
Recommended settings:
Bar 15" -18":
Bar 18" -24":
Bar 24" -:
These recommendations apply to Husqvarna's chain oil,
for other chain oils increase the oil flow by one step.

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 Air intake on the starter.
2 Air guide plate.
3 Fins on the flywheel.
4 Cooling fins on the cylinder.
5 Cylinder cover (directs cold air over the cylinder).
3
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.
2 turns from the closed position.
3 turns from the closed position.
4 turns from the closed position.
WARNING! The engine must not be
running when making adjustments.
