MAINTENANCE WORK ON CHASSIS AND ENGINE »
Activating the ignition curve for low-octane fuel
If you are traveling to a country where fuel having at least 95 octane (ROZ)
is not available, you can easily activate the corresponding ignition curve.
A socket connector [1] is located on a brown-black cable near the digital box.
If the two connectors are connected to each other, the ignition curve for fuel
having at least 95 octane (ROZ) is activated.
If you disconnect the plug and socket connection, the ignition curve for fuel
having 80 - 94 octane (ROZ) is activated. Although this causes the engine to
lose some of its power output, it prevents poor glow ignitions and engine
damage.
IF FUEL HAVING AT LEAST 95 OCTANE (ROZ) IS NOT AVAILABLE, THE IGNITION
CURVE FOR 80 - 94 OCTANE (ROZ) MUST BE ACTIVATED TO PREVENT ENGINE
DAMAGE.
Adjust idling speed *
Use the adjusting screw [2] to adjust the basic position of the throttle valve
and, thus, the idle speed.Turning in clockwise direction will increase the idling
speed, turning in counterclockwise direction will reduce the idling speed. Normal
idling speed 1400 - 1500 rpm.
Draining the carburetor float chamber *
Following every wet-cleaning procedure, the float chamber of the carburetor
should be drained in order to remove any water that may have penetrated into
it. Water in the float chamber causes engine malfunction.
Carry out this job with the engine being cold.
Close the fuel tap.
Put one end of the hose [3] that leads downward behind the engine into a
collecting vessel.
Open the drain plug [4] (turning it counterclockwise) by several turns, and
drain the fuel from the float chamber.
Then, retighten the drain plug and open the fuel tap.
FUEL IS HIGHLY FLAMMABLE AND TOXIC. BE EXTREMELY CAUTIOUS WHEN HAN-
DLING FUEL. NEVER PERFORM ANY WORK ON THE FUEL SYSTEM NEAR OPEN
FIRE OR BURNING CIGARETTES. ALWAYS ALLOW THE ENGINE TO COOL DOWN FIRST.
WIPE UP ANY SPILT FUEL IMMEDIATELY. MATERIALS SATURATED WITH FUEL ARE
HIGHLY FLAMMABLE, AS WELL. IF YOU HAVE ACCIDENTALLY SWALLOWED FUEL
OR IF IT HAS GOTTEN INTO YOUR EYES, GO SEE A PHYSICIAN IMMEDIATELY.
