10-1. Check batter
y
Check whether the electrolyte level is between upper and
lower limit lines.
If the electrolyte level is close to the lower limit line, add
purified (or distilled) water.
Adding water
(1) Remove vent plugs.
(2) Add purified water to the upper limit line.
(3) Tighten vent plugs.
IMPORTANT
Make sure the tractor is level when checking electrolyte
level.
Never add purified water over the upper limit line.
Be sure to use purified water specified for battery.
WARNING
It is recommended to replace battery promptly if under
mentioned situation occurs.
- If the electrolyte level is kept below the lower limit line
while operating, it may accelerate deterioration of internal
metals and decreasing of electrolyte. It may result
explosion of battery.
- If the inner metal plates are exposed because of
decreasing electrolyte, addition of water cannot
compensate and there is a risk of explosion.
