cold and the outside temperature is low. To help the engine burn
the increased amount of fuel, it must be supplied with additional
oxygen by pulling the cold start button.
Info
If the engine is warm, the cold start button must be deacti-
vated.
Possible states
• The cold start button is activated – The cold start button is
pulled out all the way and turned by a ¼ turn.
• The cold start button is deactivated – A further ¼ turn returns
the cold start button back to the basic position.
6.19 Idle speed adjusting screw
H02419-11
The idle setting of the throttle valve body has a big influence on
the vehicle's starting behavior, on stable idling, and on vehicle
response when the throttle is opened.
An engine with a correctly set idle speed is easier to start than an
engine with the idle speed set incorrectly.
The idle speed is adjusted using the idle speed adjusting
screw
1
.
Decrease the idle speed by turning the idle speed adjusting screw
clockwise.
Increase the idle speed by turning the idle speed adjusting screw
counterclockwise.
