Hand decompression lever (450/525 SX)
The hand decompression lever [2] is needed only if the carburetor overflows
after a fall. To "pump the engine free", pull the hand decompression lever
during the starting procedure.
The outer end of the lever must provide for a backlash of approx. 10mm (0.4
in) at all times. Only thereafter may it cause valve motion (to be
recognized by the stronger resistance which the hand decompression lever
encounters).
Hand brake lever
The hand brake lever [3] is mounted on the handlebars on the right and
actuates the front wheel brake. The adjusting screw [B] can be used to change
the basic position of the hand brake lever (see "Maintenance").
Short circuit button (SX/XC)
The short circuit button [4] turns off the engine. When pressing this button,
the ignition circuit is short-circuited.
Combination switch (EXC)
The light switch has 2, respectively 3 switch positions.
[A] = Light off (this function is not available in all models)
[B] = Low beam on
[C] = High beam on
You may use button [5] to actuate the horn.
The red short circuit button [6] serves to switch off the engine. Leave the
switch pressed until the engine stops.

Hot start lever (250 SX-F)
If you pull the red hot start lever [1] during the starting procedure backward,
a bore in the carburetor will be opened through which the engine may take in
additional air. The result is a „lean“ fuel-air mixture of the type needed for
hot starts.
