2003 YAMAHA KODIAK 400 engine

4-45
CAUTION:_

Do not use accessories requiring more
than the above maximum capacity. This
may overload the circuit and cause the
fuse to blow.


If accessories are used without the engine
running or with the headlights turned on,
the battery will lose its charge and engine
starting may become difficult.


Do not use an automotive cigarette lighter
or other accessories with a plug that gets
hot because the jack can be damaged.

CAUTION:_ Use only unleaded gasoline. The use of leaded
gasoline will cause severe damage to internal
engine parts, such as the valves and piston
rings, as well as to the exhaust system. _
WARNING
_

Do not overfill the fuel tank. Fuel expands
when it heats up. If the fuel tank is over-
filled, fuel could spill out due to heat from
the engine or the sun.


Be careful not to spill fuel, especially on
the engine or exhaust pipe which can
cause a fire and severe injury. Wipe up any
spilled fuel immediately.


Do not refuel right after the engine has
been running and is still very hot.


Be sure the fuel tank cap is closed secure-
ly.

or oils of a higher quality than specified. In
addition, do not use oils labeled “ENERGY
CONSERVING II” or higher.

Coolant
Check the coolant level in the coolant reservoir
when the engine is cold. (The coolant level will
vary with engine temperature.) The coolant level is
satisfactory if it is between the minimum and max-
imum level marks on the coolant reservoir. If the
coolant level is at or below the minimum level
mark, add distilled water to bring the level up to the
maximum level mark. Change the coolant every
two years. (See pages 8-45–8-55 for details.)CAUTION:_ Hard water or salt water is harmful to the en-
gine. You may use soft water if you cannot get
distilled water. _
Coolant reservoir capacity
(up to the maximum level mark):
0.25 L

to escape before completely removing the cap. _
EBU01083
Throttle lever
Check to see that the throttle lever operates cor-
rectly. It must open smoothly and spring back to
