MAINTENANCE
32 – English
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.
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.
Oiling the air filter
Always use special filter oil. 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 amount of grease at
the factory. However, before using the machine you
should check that the bevel gear is filled 3/4 full with
grease. Use JONSERED 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.
