inspecting the oil level.
 When inspecting the oil level, do not screw
the dipstick into the oil tank. Insert the gauge
lightly.

CAUTION:
 Do not add any chemical additives.
Engine oil also lubricates the clutch and
additives could cause clutch slippage.
 Do not allow foreign material to enter the
crankcase.
(Except for USA and CDN)
CAUTION:
 Do not add any chemical additives or use
oils with a grade of CD a or higher.
 Do not use oils labeled “ENERGY CON-
SERVING II ” b or higher. Engine oil also
lubricates the clutch and additives could
cause clutch slippage.
 Do not allow foreign materials to enter the
crankcase.

BATTERY INSPECTION AND CHARGING
WARNING
Batteries generate explosive hydrogen gas
and contain electrolyte which is made of
poisonous and highly caustic sulfuric acid.
Therefore, always follow these preventive
measures:
 Wear protective eye gear when handling
or working near batteries.
 Charge batteries in a well-ventilated area.
 Keep batteries away from fire, sparks or
open flames (e.g., welding equipment,
lighted cigarettes).
 DO NOT SMOKE when charging or han-
dling batteries.
 KEEP BATTERIES AND ELECTROLYTE
OUT OF REACH OF CHILDREN.
 Avoid bodily contact with electrolyte as it
can cause severe burns or permanent eye
injury.
FIRST AID IN CASE OF BODILY CONTACT:
EXTERNAL
 Skin — Wash with water.
 Eyes — Flush with water for 15 minutes
and get immediate medical attention.
INTERNAL
 Drink large quantities of water or milk fol-
lowed with milk of magnesia, beaten egg
or vegetable oil. Get immediate medical
attention.
CAUTION:
Charging time, charging amperage and
charging voltage for an MF battery are dif-
ferent from those of conventional batteries.
The MF battery should be charged as
explained in the charging method illustra-
tions. If the battery is overcharged, the
electrolyte level will drop considerably.
Therefore, take special care when charging
the battery.
