MAINTENANCE
4. Use a wet cloth to clean the area around the level
references and make sure that the electrolyte level is
between the MAXIMUM and MINIMUM reference marks.
Do not dry the battery with a dry cloth, because static
electricity may cause fire or explosion.
5. If the electrolyte level is below the intermediate point
between the MAXIMUM and MINIMUM reference marks,
remove the plug (2) and add distilled water up to the
MAXIMUM level.
REMARK
q Do not add distilled water or electrolyte beyond the level
indicated, as this would reduce the battery service life and
electrolyte leakage could result.
q If the distilled water added goes over the MAXIMUM
reference mark, take out excess electrolyte with a small
pump and neutralise it with sodium bicarbonate, then rinse
out with abundant running water or consult the Komatsu
distributor or the battery manufacturer.
6. After topping up, screw in the plug (2).
7. Refit the battery on the machine, making sure it is well
fixed and connect the cables. (For details, see "Removing
