Air Filter; Bevel Gear; Drive Shaft - Husqvarna 343F Operator's Manual

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.
An oiled foam plastic filter (available as an accessory) must
be used if the machine is operated in extremely dusty
conditions. See instructions under the heading Oiling the air
filter.

MAINTENANCE
Oiling the air filter
Always use HUSQVARNA filter oil, art. no. 531 00 92-48.
The filter oil contains a solvent to make it spread evenly
through the filter. You should therefore avoid skin contact.
Put the filter in a plastic bag and pour the filter oil over it.
Knead the plastic bag to distribute the oil. Squeeze the
excess oil out of the filter inside the plastic bag and pour off
the excess before fitting the filter to the machine. Never use
common engine oil. This would drain through the filter quite
quickly and collect in the bottom.
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.

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.

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.
