2-20 PERIODIC MAINTENANCE
BATTERY SOLUTION LEVEL CHECK
Battery solution level should be between UPPER level and
LOWER level.
If level is low, add distilled water only.
Once the battery has been initially serviced, NEVER
add diluted sulfuric acid, or you will damage the bat-
tery. Follow the battery manufacture’s instructions for
specific maintenance procedures.
BATTERY SOLUTION GRAVITY CHECK
Measure gravity of battery solution using hydrometer.
Battery solution gravity : 1.28 at 20°C
\ 09900-28403 : Hydrometer
