MAINTENANCE
Maintenance schedule
Below follows some general maintenance instructions.
If you need further information please contact your service
workshop.
Daily maintenance
1.Clean the outside of the
machine.
2.Make sure the throttle
trigger lock and the
throttle function correctly
from a safety point of
view.
3.Check that the stop switch
functions.
4.Check that the cutting
head does not rotate while
idling.
5.Clean the air filter.
Replace if necessary.
6.Check that the guard is
undamaged and not
cracked. Replace the
guards if they have been
exposed to impact or are
cracked.
7.Check that the trimmer
head is undamaged and
not cracked. Replace the
trimmer head if necessary.
8.Check that the locking
nut is tight.
9.Check that all nuts and
screws are tightened.
10. Make sure the harness is
not damaged.
11. Check that the blade is
well centred, is sharp, and
is not cracked. An
uncentred blade causes
vibrations that can result
in damage to the machine.
12. Check that the blade‘s
transport guard is intact
and that it can be secured
correctly.
Air filter
The air filter should be
cleaned regularly removing
dust and dirt to avoid:
• carburettor malfunction
• starting problems
• reduced engine power
• unnecessary wear to
engine parts
• abnormal fuel
consumption
Clean the filter after every
25 hours or more regularly
if operating conditions are
exceptionally dusty.
Cleaning the air filter
Dismantle the air filter cover and remove the air filter. Wash in
clean, warm soapy water. Ensure that the filter is dry before
refitting. An air filter used for a long period of time can never
be cleaned completely. Therefore it is necessary to replace the
filter from time to time with a new filter. A damaged air filter
must always be replaced.
If the machine is used in dusty conditions the air filter
should be soaked in oil, see the section on “Oiling the air
filter“.
The angle gear is filled with a
sufficient quantity of grease
at the factory. However,
before using the machine you
should check that the angle
gear is filled to 3/4 with
grease. Use HUSQVARNA
special grease.
Normally, the grease does not
need to be changed except
when repairs are carried out.
Oiling the air filter
Always use HUSQVARNA
filter oil, order no. 503 47
73-01. 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 the 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
on the machine. Never use common engine oil. This would
drain through the filter quite quickly and collect in the
bottom.
