4.7 Fuel and Refuelling
WARNING
■
The fuel used for this lawn mower 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 lawn
mower are dry before attempting to start the
engine.
►
Do not smoke.
► Do not refuel in the vicinity of flames.
► Before refilling the tank, 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 lawn mower with petrol in
the tank inside a building.
■ Breathing in petrol fumes may result in poison‐
ing.
► Do not breathe in petrol fumes.
► Refuel in a well-ventilated place.
■ The lawn mower warms up while working. The
petrol 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 lawn mower 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.
►
If clothing comes into contact with petrol:
change clothing.
■ Petrol poses a risk to the environment.
► Do not spill fuel.
► Dispose of petrol in accordance with regula‐
tions and in an environmentally acceptable
way.
■
If petrol comes into contact with the skin or
eyes, this may cause irritation.
► Avoid contact with petrol.
► In the event of contact with the skin: wash
the affected areas with plenty of soap and
water.
►
In the event of contact with the eyes: rinse
the eyes with plenty of water for at least 15
minutes and seek medical attention.
■
The lawn mower's ignition system generates
sparks. Sparks may escape and cause fires
and explosions in highly inflammable or explo‐
sive environments. This may result in serious
or fatal injury to people and damage to prop‐
erty.
►
Use the spark plugs described in the engine
instruction manual.
► Screw in the spark plug and tighten.
► Press on the spark plug socket firmly.
