Note! The machine is equipped with a two-stroke engine 
and must always be run using a mixture of petrol 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 or leaded petrol.
• The lowest recommended octane grade is 90 (RON). If 

you run the engine on a lower octane grade than 90 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.
• A poor oil quality and/or too high oil/fuel ratio may 

jeopardise function and decrease the life time of 
catalytic converters.

1:50 (2%) with HUSQVARNA two-stroke oil.

1:33 (3%) with oils class JASO FB or ISO EGB formulated 
for air-cooled, two-stroke engines.

• 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.

• 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 0

°

C (32

°

F) 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 (petrol and 2-stroke oil).

• Move the machine at least 3 m from the refuelling point 

before starting it.

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

off the spillage and allow remaining fuel to evaporate.

2 If you have spilt 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.
