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
carburetor and also filters the fuel. The fuel
cock has three 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.
RES: With the lever in this position fuel flows
to the carburetor from the reserve sec-
tion of the fuel tank after the main sup-
ply of the fuel has been depleted.
Normal riding is possible with the lever
is in this position, but it is recommended
to add fuel as soon as possible.
COLD STARTER KNOB
When cold, the engine requires a richer air-fuel
mixture for starting. A separate starter circuit,
which is controlled by the cold starter knob 1,
supplies this mixture. Pull the cold starter knob
out to open the circuit for starting. When the
engine has warmed up, push it in to close the
circuit.
HOT STARTER LEVER
The hot starter lever 1 is used when starting a
warm engine.
Use the hot starter lever when starting the
engine again immediately after it was stopped
(the engine is still warm). Pulling the hot starter
lever injects secondary air to thin the air-fuel
mixture temporarily, allowing the engine to be
started more easily.
