Gas Tank Valve

The ATV has a valve attached to the gas tank. There are
three positions: ON, RES, and OFF.
78
In the OFF position, the valve will not allow gasoline to
flow to the carburetor. In the ON position (the normal
operating position), gasoline will flow from the tank to
the carburetor. In this position, 4.54 L (1.2 U.S. gal.) will
remain in the tank as a reserve quantity. Moving the
valve to the RES position will allow the operator to use
the remaining gasoline in the tank. When turning the
valve to any of the three positions, make sure the indica-
tor is pointed directly at the position desired.
REMOVING/INSPECTING
Drain the gas tank prior to this procedure.

vent hose is securely connected to the carburetor and the
opposite end is always open.
