MAINTENANCE
Spark plug
The condition of the spark plug is affected by:
• An incorrect carburetor setting.
• An incorrect fuel mixture (too much or faulty oil).
• A dirty air filter.
These factors cause deposits on the spark plug electrode that
may result in malfunction or starting difficulties.
Air filter
The air filter (A) should be
cleaned regularly removing
dust and dirt to avoid:
• carburetor malfunction
• starting problems
• reduced engine power
• unnecessary wear to
engine parts
• abnormal fuel consump-
tion
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 (B) 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.
0,5 mm
If the machine is low on
power, difficult to start or
runs poorly while idling
always check the spark plug
first before taking other
action.
If the spark plug is dirty,
clean it and at the same time
check that the electrode gap is
0.5 mm. The spark plug
should be changed after about
one month of operation or
earlier if necessary.
NOTE! Always use the recommended type of spark plug. An
incorrect spark plug can damage the cylinder/piston.
Cleaning and
lubrication
After you have used the
machine clean any resin and
plant residue from the blades
using cleaning agent 531 00
60-75 (UL22).
Always lubricate the blade
runners with special grease
531 00 60-74 (UL 2001)
before use.
Gearbox
There is a grease nipple (A)
on the gearbox. Use a grease
gun to top up with grease.
This should be carried out
after approximately every 20
working hours. Use
Husqvarna special grease,
No. 503 98 96-01.
Note that the gearbox must
not be filled completely with
grease. The grease expands
as the machine heats up
during operation. If the
gearbox was completely
filled with grease it could
damage the seals and lead to leakage.
The lubricant in the gearbox does not normally need to be
replaced other than with repair.
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.
