NOTE:_

When the switch is set to “LOCK”, the differ-
ential gear lock indicator and indicator light
will flash until the differential gear is locked.


When the indicator and indicator light are
flashing, turning the steering wheel back and
forth will help the differential gear lock to en-
gage.


Riding before the differential gear lock is
properly engaged (e.g., when the indicator
and indicator light are flashing) will cause the
engine speed to be limited until engagement
is complete.

Accelerator pedal
Press the accelerator pedal down to increase en-
gine speed. Spring pressure returns the pedal to
the rest position when released. Always check that
the accelerator pedal returns normally before start-
ing the engine.
Before starting the engine, check the accelerator
pedal to be sure it is operating smoothly. Make
sure the accelerator pedal fully returns to the idle
position as soon as it is released.
WARNING
Malfunction of the accelerator pedal could
make it difficult to speed up or slow down
when you need to. This could cause an acci-
dent. Check the operation of the accelerator
pedal before you start the engine. If the accel-
erator pedal does not work smoothly, check
for the cause. Correct the problem before oper-
ating the vehicle or consult a Yamaha dealer.

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.


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

Engine oil
Make sure the engine oil is at the specified level.
Add oil as necessary. (See pages 8-23–8-33.)CAUTION:_

In order to prevent clutch slippage (since
the engine oil also lubricates the clutch),
do not mix any chemical additives. Do not
use oils with a diesel specification of “CD”
or oils of a higher quality than specified. In
addition, do not use oils labeled “ENERGY
CONSERVING II” or higher.


Make sure that no foreign material enters
the crankcase.

quantity:
See page 10-2.

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 additional coolant to bring the level up to
maximum level mark. If coolant is not available,
add distilled water. Change the coolant every two
years. (See pages 8-47–8-49 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):
0.35 L (0.31 Imp qt, 0.37 US qt)

WARNING
Wait for the engine and radiator to cool before
removing the radiator cap. You could be
burned by hot fluid and steam blown out under
pressure. Always put a thick rag over the cap
when opening. Allow any remaining pressure
to escape before completely removing the cap.
