Gearbox
There is a grease plug on the
gearbox (A). Remove the
plug and insert a 4-5 cm
string from the tube of
grease supplied with the
hedge trimmer. This should
be carried out after approxi-
mately every 20 working
hours. Use Husqvarna
special grease,
No 503 98 96-01.
The lubricant in the gearbox
does not normally need to
be replaced other than with
repair.
Lubrication
Always lubricate the blade
runners with special grease
531 00 60-74 (UL 21)
before use.
Spark plug
The condition of the spark plug is affected by:
• An incorrect carburettor 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.
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.
The spark plug is accessed
from under the cylinder
cover, which is removed by
loosening the four bolts (A).
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.

Air filter
The air filter (A) should be
cleaned regularly removing
dust and dirt to avoid:
• carburettor 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.
