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 function to
operate correctly. Speak to your servicing
dealer when you select your chain oil.
• Use Husqvarna chain oil for maximum saw chain life
and to prevent negative effects on the environment.
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 34 .
• Remove the cap to the chain oil tank.
• Fill the chain oil tank with chain oil.
• Attach the cap carefully.
