BATTERY MAINTENANCE
WARNING
GASES FROM BATTERY can explode.
• Keep sparks, flame, and cigarettes away from battery.
BATTERY ACID can burn eyes and skin.
CHECKING SPECIFIC GRAVITY
Check each battery cell with a hydrometer. A fully charged battery will have a specific gravity of 1.260. Charge the battery if the reading is below 1.215.
NOTE: Correct the specific gravity reading by adding four gravity points (0.004) for every five degrees the electrolyte temperature is above 80 degrees F (27 degrees (C). Subtract four gravity points (.004) for every five degrees the electrolyte temperature is below 80 degrees F (27 degrees C).

CLEANING THE BATTERY
Keep the battery clean by wiping it with a damp cloth when dirty. If the terminals appear corroded, discon- nect the battery cables and wash the terminals with an ammonia solution or a solution of 1/4 pound (0.113 kg) of baking soda and 1 quart (0.946 l) of water. Be sure the battery vent plugs (if equipped) are tight so that none of the solution enters the cells.
After cleaning, flush the outside of the battery, the bat- tery compartment, and surrounding areas with clear water. Coat the battery terminals lightly with petroleum jelly or a
Keep the battery clean and dry. Moisture accumulation on the battery can lead to more rapid discharge and early battery failure.
