OPERATION
3. Measuring the specific gravity using a hydrometer
is a way to determine the charge level, and
condition of the batteries (Figure 69). If one or
more of the battery cells test lower than the other
battery cells (0.050 or more), the cell is damaged,
shorted, or is about to fail.
FIG. 69
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. Check the
hydrometer readings against the following chart to
determine the remaining battery charge level:
SPECIFIC GRAVITY
at 275 C
1.265
1.223
1.185
1.148
1.110
NOTE: If the readings are taken when the battery
electrolyte is any temperature other than 27_C, the
reading must be temperature corrected. Add or
subtract to the specific gravity reading 0.004, 4 points,
for each 6_C above or below 27_C.
4. Keep battery tops and terminals clean and dry.
To clean batteries:
a. Mix a strong solution of baking soda and water
(Figure 70).

b. Brush solution sparingly over battery tops,
terminal and cable connectors.
NOTE: Do not allow baking soda solution to enter
battery cells.
c. Use wire brush to clean terminal post and
cable connections.
d. After cleaning, apply a coating of clear battery
post protectant to terminals and cable
connections.
5. Check for loose or worn cables. Replace if worn.

MACHINE JACKING

Use designated locations under the solution tank for
jacking up machine. Use a piece of wood to distribute
machine weight load (Figure 71).
Always stop machine on a flat level surface and block
machine tires before jacking up machine.
FIG. 71
FOR SAFETY: When servicing machine, block
machine tires before jacking machine up.
FOR SAFETY: When servicing machine, jack
machine up at designated locations only. Block
machine up with jack stands.
