FUEL HANDLING
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.
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.
Petrol
CAUTION! Always use a good quality petrol/oil mixture (at
least 90 octane). 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 and it will no longer serve its purpose.
Use low-emission petrol, also known as alkylate petrol, if it is
available.
• The lowest octane recommended is 90. If you run the
engine on a lower octane than 90 it can result in knocking.
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 HUSQVARNA two-
stroke oil, which is specially formulated for our two-stroke
engines. Mixture 1:50 (2%).
• If HUSQVARNA two-stroke oil is not available, you may
use another two-stroke oil of good quality that is intended
for air cooled engines. Contact your dealer when selecting
an oil. Mixing ratio 1:33 (3%).
• Never use two-stroke oil intended for water-cooled
outboard engines, sometimes referred to as outboard oil.
• Never use oil intended for four-stroke engines.
!
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.
