OPERATION

Checking Battery

If electrolyte is spilled on the eyes, skin or clothes, wash immediately with plenty of water. If electrolyte enters
the eyes, flush immediately with lots of fresh water and see a physician.
Do not use flames near the battery. When handling the battery, be careful of sparks generated by accidental
shorting.
Regarding other cautions in handling the battery, refer to
Electrolyte level
Electrolyte evaporates during use and the fluid level
gradually decreases. The fluid surface should be
between the LOWER LEVEL and UPPER LEVEL
lines. If there are no level lines on the battery, make
sure that the fluid surface is about 10 to 15 mm
[0.394 to 0.591 in.] above the top edges of the
plate. If the fluid level is lower, remove the caps and
add distilled water to the proper level.
Note: When pouring fresh electrolyte, pour the fluid
carefully.
Checking specific gravity of electrolyte
Check the specific gravity of the electrolyte. If the
specific gravity measured at 20 °C [68 °F] is lower
than 1.22, then charge the battery.
