Preparing The Engine For Operation - Stihl EVC 4000 Gebrauchsanleitung

English
■ 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.
► 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.
■ Overflowed petrol may ignite. This may result
in serious or fatal injury to people and damage
to property.
► Clean any surfaces contaminated with pet‐
rol.
► Avoid attempts at starting until the petrol
fumes have dispersed.
■ The engine'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.
Start the engine only with the spark
plug screwed in.
► Use the spark plugs described in this
instruction manual.
► Screw in the spark plug and tighten firmly.
► Press on the spark plug socket firmly.
■ The engine may be damaged if it is refuelled
with petrol that is not suitable.
► Use fresh, good-quality unleaded petrol.
► Note the specifications in this instruction
manual.

WARNING
■ Exhaust gases are produced when the engine
is running.
Breathing in exhaust gases may result
in poisoning.
► Do not breathe in exhaust gases.
► Work in a well-ventilated place.
► If nausea, headaches, vision problems,
hearing problems or dizziness occur: stop
working and consult a doctor.
■ The engine may be hot after it has been run‐
ning.
This may result in people burning
themselves.
► Wait until the engine has cooled down
before cleaning.
■ If the user is wearing hearing protection and
the engine is running, their perception and
assessment of noise may be limited.
► Work calmly and carefully.
■ Misfires or late ignition may occur if the engine
is switched off while it is running at high
speed.
► Allow the engine to run at minimum speed
for 20 seconds before stopping it.
5 Preparing the Engine for
Operation
5.1 Fuel
The engine is supplied with petrol from the tank
of the STIHL machine.
The engine is approved for unleaded petrol.
Unleaded petrol burns with fewer residues,
reduces deposits on the spark plug and extends
the service life of the exhaust system. The petrol
must meet the following requirements:
– The petrol is fresh, clean and unleaded.
– The octane rating of the petrol is at least 90.
– The maximum ethanol content of the petrol is
10% (E10).
STIHL recommends STIHL MotoPlus. This fuel is
virtually free of benzene, sulphur and toxic aro‐
matics.
CAUTION
■ The engine may be damaged if the correct
petrol is not used.
