FUEL HANDLING
Fuel safety
Never start the machine:
1 If you have spilled fuel on it. 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.
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 gas 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.
Fuel
CAUTION! The machine is equipped with a two-stroke engine
and must always been run using a mixture of gasoline 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.
Gasoline
CAUTION! Always use a quality gasoline/oil mixture with an
octane rating of at least 87 octane ((RON+MON)/2). If your
machine is equipped with a catalytic converter (see chapter
on Technical data) always use a good quality unleaded
gasoline/oil mixture. Leaded gasoline will destroy the catalytic
converter.
Use low-emission gasoline, also known as alkylate gasoline,
if it is available.
This engine is certified to operate on 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 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.
!
WARNING! Take care when handling fuel.
Bear in mind the risk of fire, explosion and
inhaling fumes.
!
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.
