Lubrication (oil injection models)
1. Grease the spark plug threads and in-
stall the spark plug(s) and torque to
proper specification. For information on
spark plug installation, see page 44.
2. Fill the oil tanks. This prevents the for-
mation of condensation. For models with
a remote oil tank, it may be necessary to
manually override the control unit to
completely fill the engine oil tank.
3. Change the gear oil. For instructions,
see page 50. Inspect the oil for the pres-
ence of water which indicates a leaky
seal. Seal replacement should be per-
formed by an authorized Yamaha dealer
prior to use.
4. Grease all grease fittings. For further de-
tails, see page 43.

Battery care
WARNING
EWM00330
Battery electrolytic fluid is dangerous; it
contains sulfuric acid and therefore is
poisonous and highly caustic.
Always follow these preventive mea-
sures:
●
Avoid bodily contact with electrolytic
fluid as it can cause severe burns or
permanent eye injury.
●
Wear protective eye gear when han-
dling or working near batteries.
Antidote (EXTERNAL):
●
SKIN - Flush with water.
●
EYES - Flush with water for 15 minutes
and get immediate medical attention.
Antidote (INTERNAL):
●
Drink large quantities of water or milk
followed by milk of magnesia, beaten
egg, or vegetable oil. Get immediate
medical attention.
Batteries also generate explosive hydro-
gen gas; therefore, you should always
follow these preventive measures:
●
Charge batteries in a well-ventilated ar-
ea.
●
Keep batteries away from fire, sparks,
or open flames (for example: welding
equipment, lighted cigarettes, and so
on.)
●
DO NOT SMOKE when charging or han-
dling batteries.
KEEP BATTERIES AND ELECTROLYTIC
FLUID OUT OF REACH OF CHILDREN.
Batteries vary among manufacturers. There-
fore the following procedures may not al-
ways apply. Consult your battery
manufacturer’s instructions.
