Note! The machine is equipped with a two-stroke engine 
and must always be run using a mixture of gasoline and 
two-stroke oil. It is important to accurately measure the 
amount of oil to be mixed to ensure that the correct mixture 
is obtained. When mixing small amounts of fuel, even small 
inaccuracies can drastically affect the ratio of the mixture.

• Use good quality unleaded gasoline.
• The lowest recommended octane grade is 87 

((RON+MON)/2). If you run the engine on a lower octane 
grade than 87 so-called knocking can occur. This gives 
rise to a high engine temperature and increased bearing 
load, which can result in serious engine damage.

• When working with continuous high revs (e.g. limbing) a 

higher octane is recommended.

Avoid running at a too high speed for extended periods 
during the first 10 hours.

• 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.

1:50 (2%) for all engines.

• Always mix the gasoline and oil in a clean container 

intended for fuel.

• Always start by filling half the amount of the gasoline to 

be used. Then add the entire amount of oil. Mix (shake) 
the fuel mixture. Add the remaining amount of gasoline.

• 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.

• We recommend the use of special oil (chain oil) with 

good adhesion characteristics.

• Never use waste oil. This results in damage to the oil 

pump, the bar and the chain.

• It is important to use oil of the right grade (suitable 

viscosity range) to suit the air temperature.

• In temperatures below 32

°F (0°C) some oils become too 

viscous. This can overload the oil pump and result in 
damage to the oil pump components.

• Contact your service agent when choosing chain oil.

Clean the area around the fuel cap. Clean the fuel and 
chain oil tanks regularly. The fuel filter must be replaced at 
least once a year. Contamination in the tanks causes 
malfunction. Make sure the fuel is well mixed by shaking 
the container before refuelling. The capacities of the chain 
oil tank and fuel tank are carefully matched. You should 
therefore always fill the chain oil tank and fuel tank at the 
same time.

• Never refuel the machine while the engine is running.
• Make sure there is plenty of ventilation when refuelling 

or mixing fuel (gasoline and 2-stroke oil).

• Move the machine at least 10 ft (3 m) from the refuelling 

point before starting it.

• Never start the machine:
1 If you have spilled fuel or chain oil on the machine. Wipe 

off the spillage and allow remaining fuel to evaporate.

2 If you have spilled fuel on yourself or your clothes, 

change your clothes. Wash any part of your body that 
has come in contact with fuel. Use soap and water.

3 If the machine is leaking fuel. Check regularly for leaks 

from the fuel cap and fuel lines.
