CONTROL FUNCTIONS
REAR BRAKE PEDAL
The rear brake pedal "1" is located on the right
side of the machine. Press down on the brake
pedal to activate the rear brake.
FUEL COCK
The fuel cock supplies fuel from the tank to car-
buretor and also filters the fuel. The fuel cock
has the two positions:
OFF:
With the lever in this position, fuel will not flow.
Always return the lever to this position when the
engine is not running.
ON:
With the lever in this position, fuel flows to the
carburetor. Normal riding is done with the lever
in this position.
STARTER KNOB (CHOKE)
When cold, the engine requires a richer air-fuel
mixture for starting. A separate starter circuit,
which is controlled by the starter knob "1", sup-
plies this mixture. Pull the starter knob out to
open the circuit for starting. When the engine
has warmed up, push it in to close the circuit.
