Check Electrolyte Specific Gravity
--- every 250 hours
d
CAUTION:
Battery gas can explode. Keep sparks and flames
away from batteries. Use a flashlight and a mirror to
check the battery electrolyte solution level.
Sulfuric acid in battery electrolyte solution is
poisonous. It is strong enough to burn skin, eat
holes in clothing, and cause blindness if splashed
into the eyes.
Never check the battery charge by placing a metal
object across the posts. Use a battery tester or
hydrometer.
Always remove the grounded (-) battery lead first
and attach it last.
Avoid hazard by:
1. Filling batteries in a well-ventilated area.
2. Wearing eye protection and rubber gloves.
3. Avoiding breathing fumes when electrolyte solution
is added.
4. Avoiding spilling or dripping electrolyte solution.
5. Using proper booster battery starting procedures.

Specific gravity of battery fluid
If you spill acid on yourself, call 911, then:
1. Flush your skin with water.
2. Apply baking soda or lime to help neutralize
the acid.
3. If splashed in eyes, flush with water for
10 to 15 minutes. Get medical attention
immediately.
If acid is swallowed, call 911, then:
1. Drink large amounts of water or milk.
2. Then drink milk of magnesia, beaten eggs, or
vegetable oil.
3. Get medical attention immediately.
IMPORTANT: Check the specific gravity of the
electrolyte when it is cool, not immediately after
operation.
Check the electrolyte specific gravity in each battery
cell.
The lowest limit of the specific gravity for the
electrolyte varies depending on electrolyte
temperature. The specific gravity should be kept
within the range shown below. Charge the battery if
the specific gravity is below the limit.
