5.1 Fuel information

A high performance two-stroke engine operated
with a petrol:oil mixture (petrol + oil = fuel mixture)
or with a special fuel mixture for two-stroke
engines available from specialists powers this
machine.
We recommend the proprietary "Aspen 2-takt"
special fuel mixture. Please observe the special
fuel manufacturer's instructions.
Information on individual mixing of the fuel mixture
Normal or super unleaded petrol can be used for
individual mixing purposes (minimum octane
number 92 RON).
When using a particularly high quality proprietary
2-stroke engine oil such as the "solo by AL-KO
Profi 2T-Motoröl" which we supply, we
recommend an oil:petrol mixing ratio of 1:50 (2%).
When using other brands of 2-stroke oil we
recommend a mixing ratio of 1:25 (4%).
Only use proprietary 2-stroke engine oil!
Never store fuel mixture longer than 3 - 4 weeks.

5.2 Fuelling
While fuelling always follow all safety instructions
and take all safety precautions.
Handle fuel only with the engine turned off.
Carefully clean the area around the filler inlet.
Place the machine with the fuel inlet pointing
upwards. Unscrew the tank lid and fill the fuel
mixture up to the lower edge of the filler neck. Use
a funnel with filter to prevent tank contamination.
After filling the tank replace the tank lid and tighten
firmly.

6 Starting
Observe the safety instructions when starting.
Take up a safe position
When first starting or if the fuel tank has been
completely drained and has been refilled, press
primer (8) several times (at least 5x) until the fuel
is visible in the plastic bulb.
Press the decompression valve (6) every time
before pulling on the starter handle to make the
startup process easier. After starting, the
decompression valve automatically returns to its
normal position.
When the engine is cold:
With the choke lever up ( ) and with the
decompression valve held down, start the engine
by pulling the starter handle up in a straight line
several times until the motor is briefly audible
(ignition).
Then immediately move the choke lever down (
). Continue to start (with decompression valve
held down) until the engine runs evenly.
When the engine is warm:
With the choke lever down ( ) and with the
decompression valve activated, start the engine
by pulling the starter handle up in a straight line
several times until the motor runs evenly.
The following instructions are aimed at increasing
the service life of the starter rope and of the starter
mechanism:
• Always pull the rope out in a straight line.
• Do not let the rope drag across the edge of the
rope eyelet.
• Do not pull rope all the way out - risk of the rope
breaking.
• Always manually guide the rope back into its
start position with your hand on the starter grip -
do not let it retract on its own.
