BATTERY MAINTENANCE
WARNING: Fire Or Explosion Hazard.
Batteries Emit Hydrogen Gas. Keep Sparks And
Open Flame Away. Keep Battery Compartment
Open When Charging.
FOR SAFETY: When servicing machine, wear
protective gloves and eye protection when
handling batteries and battery cables. Avoid
contact with battery acid.
1. Check the specific gravity using a hydrometer to
determine the charge level and the condition of the
batteries (Figure 32). If one or more of the battery
cells read lower than the other battery cells (0.050
or more), the cell is damaged, shorted, or is about
to fail. Check the hydrometer readings against the
following chart to determine the remaining battery
charge level.
NOTE: Do not take readings immediately after adding
distilled water. If the water and acid are not thoroughly
mixed, the readings may not be accurate.

the reading must be temperature corrected. Add or
subtract to the specific gravity reading 0.004, 4 points,
for each 6_C(43_F) above or below 27_C(80_F).
2. Always follow proper charging instructions
(See CHARGING BATTERIES).
3. Check the electrolyte level (A) in each battery cell
after charging batteries. The level should be

To clean batteries:
FOR SAFETY: When servicing machine, wear
protective gloves and eye protection when
handling batteries and battery cables. Avoid
contact with battery acid.
a. Mix a strong solution of baking soda and water
(Figure 34).
FIG. 34
b. Brush the solution sparingly over the battery
tops and cable connectors.
NOTE: Do not allow baking soda solution to enter
battery cells.
