The machine is fitted with a two-stroke engine and must
always be run on a mixture of petrol and two-stroke oil. It is
important to measure the quantity of oil accurately, to ensure
the correct mixture ratio. Small discrepancies in the amount of
oil have a great bearing on the proportions of the fuel mixture
when mixing small amounts of fuel.
Always provide good ventilation when
Always use an oil-mixed

octane). If your machine is
equipped with a catalytic
converter, (see "technical
data") an unleaded, oil
mixed quality petrol should
always be used. A leaded

• If HUSQVARNA two-stroke oil is not available you can
use a high quality two-stroke oil intended for air cooled
engines. Contact your dealer when selecting an oil.
Mixing ratio: 1:33 (3%).
• Never use two-stroke oil intended for water cooled out-
board motors, so-called outboard motor oil.
• Never use oil intended for four-stroke engines.

• Always start by filling half the quantity of petrol required.
Then add the entire oil quantity. Mix (shake) the fuel
mixture. Fill the remaining quantity of petrol.
• Mix (shake) the fuel mixture carefully before filling in the
machine's fuel tank.
• Do not mix more than max. one month's supply of fuel.
• If the machine is not used for a long period of time, the fuel
tank should be emptied and cleaned.
• Clean around the fuel cap. Contamination in the tank can
• Ensure that the fuel is well mixed by shaking the container
before filling the tank.
The catalytic converter muffler gets very hot
during and after use. This also applies
during idling. Be aware of the fire hazard,
especially when handling the saw near
flammable substances or vapours.
The following precautions reduce the risk
Do not smoke or place any sources of heat
in the vicinity of the fuel. Never refuel
when the engine is running. Always stop
the engine and let it cool for a few minutes
before refuelling. Open the fuel cap slowly
when fuelling so that any over pressure is
released slowly. Tighten the fuel cap
carefully after refuelling. Always move the
machine from the fuelling place before
