NOTICEECB00301In order to prevent cl utch 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 la-
beled “ENERGY CONSERVING II” or
higher.
 Make sure that no foreign material en-
ters the crankcase. EBU31761CoolantCheck the coolant level in the reservoir and
replenish if necessary. (See page 8-25.)
EBU36020Final gearMake sure there is no oil leaking from the final
gear case.EBU36030Differential gearMake sure there is no oil leaking from the dif-
ferential gear case.EBU31791Accelerator pedalBefore starting the engine, confirm that the
accelerator pedal operates correctly. It
should depress smoothly and spring back to
the idle position when released. Also check
the accelerator pedal for excessive free play.
If the accelerator pedal is not in correct work-
ing order, have the vehicle inspected before
starting off.

EBU33661CoolantThe coolant level should be checked regular-
ly. In addition, the coolant must be changed
at the intervals specified in the periodic main-
tenance chart.TIPIf genuine Yamaha coolant is not available,
use an ethylene glycol antifreeze containing
corrosion inhibitors for aluminum engines and
mix with distilled water at a 1:1 ratio.
NOTICEECB02190Mix antifreeze with distilled water only.
However, if distilled water is not available,
soft water may be used for refilling. Do not
use hard water or salt water since they are
harmful to the engine. To check the coolant level1. Park the vehicle on a level surface.
2. Wait for the engine to cool for an accurate reading.
3. Look the coolant level in the coolant res- ervoir.
Recommended coolant:YAMALUBE coolant
Coolant quantity: Coolant reservoir (up to full level):0.28 L (0.30 US qt, 0.25 Imp.qt)
Radiator (including all routes): 2.85 L (3.01 US qt, 2.51 Imp.qt)

4. If the coolant is at or below the minimumlevel mark, remove the coolant reservoir
cap and add coolant to the maximum lev-
el mark.
5. Install the reservoir cap.
To change the coolant 1. Park the vehicle on a level surface.
2. Remove the hood. (See page 8-10.) 3. When the engine is cool, remove the radi-
ator cap. WARNING! Never attempt to
remove the radiator cap when the en-
gine is hot.
