Check Electrolyte Specific Gravity--- every month
d
WARNING:
Battery gas can explode. Keep sparks and flames
away from batteries.
Use a flashlight to check the battery electrolyte level.
Sulfuric acid in battery electrolyte 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 voltmeter or
hydrometer.
Avoid hazard by:
1. Filling batteries in a well-ventilated area.
2. Wearing eye protection and rubber gloves.
3. Avoiding breathing fumes when electrolyte is added.
4. Avoiding spilling or dripping electrolyte.
5. Using proper booster battery starting procedures.

If you spill acid on yourself:
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 15 to 30
minutes. Get medical attention immediately.
If acid is swallowed:
1. Do not induce vomiting.
2. Drink large amounts of water or milk.
3. Get medical attention immediately.
IMPORTANT: Check the specific gravity of the
electrolyte after it is cooled, 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.
