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
adjust chain lubrication on page 22 .
• 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 25 .
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.
To
• Cut large branches in sections so that you have
better control over where they fall.
• Never cut through the swelling at the root of the
branch as this will slow down healing and increase
the risk of fungal attack.
