Fuel safety

Never start the machine:
1 If you have spilt fuel on it. 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.
Transport and storage
• Store and transport the machine and fuel so that there is
no risk of any leakage or fumes coming into contact with
sparks or naked flames, for example, from electrical
machinery, electric motors, electrical relays/switches or
boilers.
• When storing and transporting fuel always use approved
containers intended for this purpose.
• When storing the machine for long periods the fuel tank
must be emptied. Contact your local petrol station to find
out where to dispose of excess fuel.
• Ensure the machine is cleaned and that a complete
service is carried out before long-term storage.
• The transport guard must always be fitted to the cutting
attachment when the machine is being transported or in
storage.
WARNING! Take care when handling fuel.
!
Bear in mind the risk of fire, explosion and
inhaling fumes.

Fuel

CAUTION! The machine is equipped with a two-stroke engine
and must always been run using a mixture of petrol and two-
stroke engine 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.
WARNING! Fuel and fuel fumes are highly
!
inflammable and can cause serious injury
when inhaled or allowed to come in contact
with the skin. For this reason observe
caution when handling fuel and make sure
there is adequate ventilation.

FUEL HANDLING

Petrol
CAUTION! Always use a quality petrol/oil mixture at least 90
octane (RON). If your machine is equipped with a catalytic
converter (see chapter on Technical data) always use a good
quality unleaded petrol/oil mixture. Leaded petrol will destroy
the catalytic converter.
Use low-emission petrol, also known as alkylate petrol, if it is
available.
• The lowest octane recommended 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, which can result in serious engine damage.
• When working at continuous high revs a higher octane
rating is recommended.
Two-stroke oil
• For best results and performance use JONSERED 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.
• Mixing ratio
1:50 (2%) with JONSERED 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.
