Check battery electrolyte level
Carry out this check before operating the machine.
WARNING
z Do not use the battery if the battery electrolyte level is below
the (MINIMUM) LOWER LEVEL line. This will accelerate
deterioration of the inside of the battery and reduce the ser-
vice life of the battery. In addition, it may also cause an
explosion.
z The battery generates flammable gas and there is danger of
explosion, so do not bring fire or sparks near the battery.
z
Battery electrolyte is dangerous. If it gets in your eyes or on
your skin, wash it off with a large amount of water and con-
sult a doctor.
z
When adding distilled water to the battery, do not allow the
battery electrolyte to go above the (MAXIMUM) UPPER
LEVEL line. If the electrolyte level is too high, it may leak
and cause damage to the paint surface or corrode other
parts.
NOTE
When adding distilled water in cold weather, add it before start-
ing operations in the morning to prevent the electrolyte from
freezing.
Try to check the electrolyte level on the daily basis. Be sure to
check it at least once a month.
When checking electrolyte level from side of battery
If it is possible to check the electrolyte level from the side of the
battery, check as follows.
1. Use a wet cloth to clean the area around the electrolyte level
lines and check that the electrolyte level is between the
UPPER LEVEL (U.L.) and LOWER LEVEL (L.L.) lines.
If the battery is wiped with a dry cloth, static electricity may
cause a fire or explosion.
If the battery is wiped with a dry cloth, static electricity may
