3. CORRECT USE OF THE VEHICLE

3.1. Starting of the engine

Before starting the engine, check whether
the fuel tank is filled with fuel and 2-stroke oil at the correct mixing ratio
battery is charged and connected
battery voltage is higher than 12.4 V
Note: If "LO BA" is indicated during the starting procedure, this is not a sign for a bad
charging status of the battery. Due to the load on the battery at the starting
procedure there is a voltage drop below 12.4 V. If however the indication "LO BA"
still appears after longer standstill (approx. 10 – 15 minutes) of the vehicle, this is a
sign of bad charging status of the battery.
throttle cable is moving freely and the carburetor piston is at position of engine idling
shifting paddle is in position „NEUTRAL" (no gear engaged)
When starting take care of the following procedure:
When engine is cold, turn choke lever on carburettor into vertical position.
Push the switch to position "START" (maximum 5 seconds) until the engine starts. If the
engine does not start, repeat the starting procedure after 5 seconds.
When the engine is running, slowly return the choke lever to its previous position.

3.2. Running-in of vehicle (engine)

To achieve longer lifetime of the single engine components , it must undergo a defined running-in
procedure when operating it for the first time or after repair of parts of the crankshaft drive and/or
the cylinder/piston components.
To assure an optimum running-in phase we recommend to use for the first fuel tank filling a
somewhat richer oil/fuel mixture at a ratio of
1 : 33 (= 3 % 2-stroke oil, or 0,3 l / at 10 l of fuel).
After the running-in phase however use the prescribed oil/fuel mixture of
1 : 50 (= 2 % 2-stroke oil, or 0,20 l at 10 l of fuel)
to avoid problems like carbonization of the exhaust valve.
Attention: Before running-in the engine, adjust the main jet to the ambient atmospheric
conditions (ambient temperature and sea level). See also chapter "Carburetor
adjustment". Operating the engine with too lean jetting can cause engine damage.
