CAUTION: Contamination in the
tanks causes malfunction. Clean the fuel
tank and chain oil tank regularly and
replace the fuel filter one time a year or
more.
To do a run-in
• During the first 10 hours of operation, do not
apply full throttle without load for extended
periods.
To use the correct chain oil
WARNING: Do not use waste oil,
which can cause injury to you and
the environment. Waste oil also causes
damage to the oil pump, the guide bar
and the saw chain.
WARNING: The saw chain can
break if the lubrication of the cutting
equipment is not sufficient. Risk of
serious injury or death to the operator.
WARNING: This product has a
function that lets the fuel run out before
the chain oil. Use the correct chain oil for
this safety function to operate correctly.
Speak to your servicing dealer when you
select your chain oil.
Note: This product has an automatic chain
lubrication system. You can also adjust the oil flow.
Refer to
To check the chain lubrication on page 20
.
• Use Husqvarna chain oil for maximum saw chain
life and to minimise environmental damage.
If Husqvarna chain oil is not available, we
recommend you to use a standard chain oil.
• Use a chain oil with good adherence to the saw
chain.
• Use a chain oil with correct viscosity range that
agrees with the air temperature.
CAUTION:
If the oil is too
thin, it runs out before the fuel. In
temperatures below 0°C/32°F some
chain oils become too thick, which
can cause damage to the oil pump
components.
• Use the recommended cutting equipment. Refer
to
Accessories on page 23
.
To use the product
• Hold the product as close to your body as
possible to get the best balance. Use the
harness to support the weight of the machine
and make it easier to handle.
• Make sure that the tip does not touch the ground.
• Do not rush the work, but work steadily until all
the branches have been cut back cleanly.
• Always slow the engine to idle speed after each
working operation. Long periods at full throttle
without any load on the engine can lead to
serious engine damage.
• Always work at full throttle.
• Whenever possible position yourself so that you
can make the cut at right angles to the branch.
• Do not work with the shaft held straight out in
front of you as this increases the apparent weight
of the cutting attachment.
• Cut large branches in sections so that you have
better control over where they fall.
