Fuel and Refuelling
WARNING
■ The fuel used for this engine is petrol. Petrol is
extremely inflammable. If petrol comes into
contact with an open flame or hot objects, it
may cause fires or explosions. This may result
in serious or fatal injury to people and damage
to property.
Protect petrol from heat and fire.
► Do not spill petrol.
► If petrol is spilled: wipe up the petrol with a
cloth and wait until all parts of the machine
are dry before starting the engine.
► Do not smoke.
► Do not refuel in the vicinity of flames.
► Before refuelling, stop the engine and allow
it to cool.
► If the tank needs to be emptied: do this out
of doors.
► Start the engine at least 3 m away from the
refuelling site.
► Never store the engine with petrol in the
tank inside closed rooms.
■ Breathing in petrol fumes may result in poison‐
ing.
Do not breathe in petrol fumes.
► Refuel in a well-ventilated place.
■ The engine warms up while working. The pet‐
rol expands and overpressure may occur in
the fuel tank. Petrol may gush out when the
fuel tank cap is opened. The gushing petrol
may ignite. This may result in serious injury to
the user.
Allow the engine to cool down before
opening the fuel tank cap.
■ Clothing that comes into contact with petrol is
highly inflammable. This may result in serious
or fatal injury to people and damage to prop‐
erty.

tions and in an environmentally acceptable
