FUEL HANDLING
Two-stroke oil
• For best results and performance use HUSQVARNA two-
stroke engine oil, which is specially formulated for our air-
cooled two-stroke engines.
• Never use two-stroke oil intended for water-cooled
engines, sometimes referred to as outboard oil (rated
TCW).
• Never use oil intended for four-stroke engines.
• A poor oil quality and/or too high oil/fuel ratio may
jeopardise function and decrease the life time of catalytic
converters.
• Mixing ratio
1:50 (2%) with HUSQVARNA two-stroke oil or equivalent.
1:33 (3%) with other oils designed for air-cooled, two-
stroke engines classified for JASO FB/ISA EGB, or higher.
Mixing
• Always mix the petrol and oil in a clean container intended
for fuel.
• Always start by filling half the amount of the petrol to be
used. Then add the entire amount of oil. Mix (shake) the
fuel mixture. Add the remaining amount of petrol.
• Mix (shake) the fuel mixture thoroughly before filling the
machine’s fuel tank.
• Do not mix more than one month’s supply of fuel at a time.
• If the machine is not used for some time the fuel tank
should be emptied and cleaned.
Fuelling
• Clean the area around the fuel cap. Contamination in the
tank can cause operating problems.
• Ensure that the fuel is well mixed by shaking the container
before filling the tank.

!
WARNING! The catalytic converter muffler
gets very hot during and after use. This also
applies during idling. Be aware of the fire
hazard, especially when working near
flammable substances and/or vapours.
!
WARNING! Taking the following precautions,
will lessen the risk of fire:
Do not smoke or place hot objects near fuel.
Always shut off the engine before refuelling.
Always stop the engine and let it cool for a
few minutes before refuelling.
When refuelling, open the fuel cap slowly so
that any excess pressure is released gently.
Tighten the fuel cap carefully after refuelling.
Always move the machine away from the
refuelling area before starting.
