In order to prevent clutch slippage, do
not mix any chemical additives. TIPBe sure to wipe up any spilled oil. 7. Start the engine and drive the vehicle for
a few minutes to circulate the transmis-
sion oil.
8. Park the vehicle on a level surface, stop
the engine, and then check the transmis-
sion case for oil leakage.TIPIf oil is leaking confirm that the transmission
oil filler cap is properly installed and then have
a Yamaha dealer check the transmission. 9. Check the transmission oil level and cor-rect if necessary.

oil at the intervals specified in the general
maintenance and lubrication chart.
Checking the final gear oil level 1. Park the vehicle on a level surface.
2. Remove the final gear oil filler bolt and its gasket, and then check the oil level in the
final gear case. The oil level should be at
the brim of the filler hole.

EBU35110CoolantCheck the coolant level prior to each time you
operate the vehicle, and have a Yamaha deal-
er change the coolant every two years.
Checking the coolant level1. Park the vehicle on a level surface.
2. Remove the hood. (See page 8-10.)
3. Check the coolant level when the engine is cold (the coolant level will vary with en-
gine temperature).TIPThe coolant level in the coolant reservoir
should be between the minimum and maxi-
mum level marks.
4. If the coolant level is at or below the mini-mum level mark, remove the coolant res-
ervoir cap and add coolant to the
maximum level mark. NOTICE: If cool-
ant is not available, use distilled water
or soft tap water instead. Do not use
hard water or salt water since they are
harmful to the engine. If water has
been used instead of coolant, replace
it with coolant as soon as possible,
otherwise the cooling system will not1. Coolant reservoir cap

sion. If water has been added to the
coolant, have a Yamaha dealer check
the antifreeze content of the coolant
as soon as possible, otherwise the ef-
fectiveness of the coolant will be re-
duced.

6. Install the hood when finished servicingthe vehicle.TIPThe radiator fan automatically switches on
or off according to the temperature of the
coolant in the radiator.
If the engine overheats, see page 8-66 for
instructions.
