Drive Shaft; Spark Plug; Winter Use - Husqvarna 335LX Operator's Manual

Drive shaft

The drive shaft must be greased every three months
during full-time use. Contact your dealer if you are
uncertain about the procedure.

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 0.020 inch (0.5
mm). The spark plug should be replaced after about a
month in operation or earlier if necessary.
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.

Winter use

Running problems can occur when using the machine in
the cold and snowy conditions caused by:
• Too low engine temperature.
• Icing of the air filter and carburetor.
Special measures are therefore often required:
• Partly mask the air inlet on the starter to increase the
working temperature of the engine.
• Preheat the intake air to the carburetor by using the
heat from the cylinder.

MAINTENANCE
Temperature 5°C (41°F) or colder:
The air filter holder is prepared so it can be changed for
use in the cold. Remove the air filter cover and air filter.
Turn the winter cover anticlockwise using a screwdriver so
that the preheated air from the engine can pass inside the
carburettor compartment and prevent, for example, the air
filter from icing up (see figure).
For temperatures below 5°C (41°F) and/or in snow
conditions there is also:
• a special cover for the starter housing
• a cover for cylinder cover's air inlet should be fitted as
illustrated.
These reduce the cooling air and prevent large amounts
of snow from being sucked into the engine.
IMPORTANT! The machine MUST be returned to its
standard design at temperatures warmer than 5°C
(41°F). Otherwise there is a risk of overheating resulting
in serious engine damage.
IMPORTANT! Any maintenance other than that
described in this manual must be carried out by your
servicing dealer (retailer).
IMPORTANT! Use only HUSQVARNA replacement
parts. Use of other brands of replacement parts can
cause damage to your unit or injury to the operator or
others. Your warranty does not cover damage or liability
caused by the use of accessories and/or attachments
not specifically recommended by HUSQVARNA.
