7.2 Maintenance of Battery
7.2.1 Measure Specific Gravity (Applicable to standard battery)
When the fluid level is found below the lower limit
without a trace of electrolyte leakage, refill with
distilled water so the level will be between upper
and lower limits.
To compensate for shortage of electrolyte due to
spilling, or to measure or change the specific
gravity, remove battery cap and measure specific
gravity of electrolyte by using a hydrometer.
Only authorized personnel is allowed for checking
and mixing electrolyte.
7.2.2 Charge Battery
Disconnect the cable between battery and the unit.
Charge the battery with a 12 V battery charger. Do
not charge two batteries at the same time.
