Battery

Warning
Battery posts, terminals, and related accessories
contain lead and lead compounds, chemicals
known to the State of California to cause cancer
and reproductive harm. Wash hands after
handling.
Check the electrolyte level in the battery every 25 hours.
Always keep the battery clean and fully charged. Use a
paper towel to clean the battery case. If the battery
terminals are corroded, clean them with a solution of four
parts water and one part baking soda. Apply a light
coating of grease to the battery terminals to prevent
corrosion.
Voltage: 12 v
Checking Electrolyte Level
1. Open covers to see into the cells. The electrolyte must
be up to the lower part of the tube (Fig. 62). Do not
allow the electrolyte to get below the plates (Fig. 62).
2. If the electrolyte is low, add the required amount of
distilled water; refer to Adding Water to the Battery.
