English 5 Preparing the Engine for Operation
► 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.
5.1 Refuelling the Engine
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 85.
– The maximum ethanol content of the petrol is 10% (E10).
STIHL recommends STIHL MotoPlus. This fuel is virtually
free of benzene, sulphur and toxic aromatics.
The tank capacity is 0.9 litres.
CAUTION
￭ The engine may be damaged if the correct petrol is not
used.
STIHL recommends always using fresh, good-quality fuel
and never using a 2-stroke mixture (petrol with an oil
additive).
Do not use stale or contaminated petrol.
Avoid contaminating the tank contents with dirt and water.
Only use approved petrol (not E85).
Change the petrol brand if you hear knocking or ringing.
► If necessary, contact your specialist dealer; STIHL
recommends STIHL specialist dealers.
► Stop the engine.
► Place the STIHL machine on a level surface.
► Clean the area around the fuel tank cap with a damp cloth.
► Turn fuel tank cap (1) anti-clockwise until it can be
removed.
► Remove the fuel tank cap.
► Check the seating of the fuel filter.
► Add the petrol using a suitable funnel so that none is
spilled. Add petrol, stopping at least 15 mm short of the
fuel tank brim.
► Place the fuel tank cap on the fuel tank.
► Turn the fuel tank cap clockwise and hand tighten.
The fuel tank is sealed.
5.2 Adding Engine Oil
The engine oil lubricates and cools the engine.
CAUTION
￭ The engine is delivered without engine oil.
This may result in people burning themselves.
