NOTICE
In order to prevent clutch slippage (since
the engine oil also lubricates the clutch),
do not mix any chemical additives with oil.
Do not use oils with a diesel specification
of “CD” or oils of a higher quality than
specified. In addition, do not use oils la-
beled “ENERGY CONSERVING II” or high-
er.
Make sure that no foreign material enters
the crankcase.
12. Start the engine, and then let it idle for sever-
al minutes while checking it for oil leakage. If
oil is leaking, immediately turn the engine off
and check for the cause.
13. Turn the engine off, wait at least ten minutes,
and then check the oil level and correct it if
necessary.
14. Install the engine guard by installing the bolts,
and then tightening them to the specified
torque.

sure no foreign material enters the front
differential gear case.
4. Tighten the oil level check bolt to the speci-
fied torque.

Rear differential gear oil
Checking the rear differential gear oil level
1. Park the vehicle on a level surface.
2. Remove the rear differential gear oil filler bolt,
and then check the oil level in the rear differ-
ential gear case. The oil level should be at the
brim of the filler hole.
3. If the oil is below the brim of the filler hole,
add sufficient oil of the recommended type to
raise it to the correct level. NOTICE: Be sure
no foreign material enters the rear differ-
ential gear case.
4. Reinstall the oil filler bolt, and then tighten it to
the specified torque.
Tightening torque:

Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reaction
and lead to poor braking performance.
Be careful that water does not enter the brake
fluid reservoir when refilling. Water will signifi-
cantly lower the boiling point of the fluid and
may result in vapor lock.
Brake fluid may deteriorate painted surfaces or
plastic parts. Always clean up spilled fluid im-
mediately.
Have a Yamaha dealer inspect the brake sys-
tem if the brake fluid level goes down.
