Battery Charging (Continued)
(For non-accessible maintenance-free type batteries.)
Maintenance-free, non-accessible batteries are designed to
eliminate the need to add water. Yet the volume of electrolyte (3)
above plates may eventually become depleted due to abnormal
conditions such as high heat or improper regulator setting. Use a
voltmeter to check the state of charge. (See reference chart below
to determine if charging is necessary.)
■
Direction for Storage
1. When storing the machine for long periods of time, remove the
battery from machine, adjust the electrolyte (3) to the proper level
and store in a dry place out of direct sunlight.
2. The battery self-discharges while it is stored.
Recharge it once every three months in hot seasons and once
every six months in cold seasons.

Changing Engine Oil
CAUTION
• Be sure to stop the engine and remove the key before
changing the oil.
• Allow engine to cool down sufficiently; oil can be hot and
may cause burns.
1. To change the used oil, remove the drain plug (1) at the bottom
of the engine and drain the oil completely. The used oil can be
drained out more easily if the engine is warm.
2. Fill with the new oil up to the upper notch on the dipstick.
3. To check the oil level. Remove the dipstick, wipe it clean, insert
it and draw it out again. Check to see the oil level is between the
two marks.
