WARNING!
Battery electrolyte contains sulfuric acid and can quickly burn the skin and eat holes in clothing. If you spill acid on yourself, immediately flush the area with water.
Battery acid could cause blindness if splashed into the eyes. If acid gets into the eyes, flush them immediately with large quantities of water and see a doctor at once.
If you accidentally drink acid, drink a large quantity of water or milk, beaten egg or vegetable oil. Call a doctor or poison prevention center immediately.
When working with batteries, always wear safety glasses or goggles.
Battery generates hydrogen gas, so there is danger of an explosion. Do not bring lighted cigarettes near the battery, or do anything that will cause sparks.
Before working with batteries, shut down engine and turn the starter switch to the "O" (OFF) position.
Avoid short circuiting the battery terminals through accidental contact with metallic objects, such as tool.
When removing or installing, check which is the positive (+) terminal and negative (-) terminal.
When removing the battery, first disconnect the negative (-) terminal. When installing the battery, first connect the positive (+) terminal.

Batteries in Cold Weather
In colder weather a greater drain is placed on the batteries when they are used for the preheat cycle and when starting a cold engine. Battery performance decreases as the temperature gets lower.
In extremely cold weather, remove the batteries at night and move them to a warm location. This will help to keep them at a higher power level.
Inspection of Battery Electrolyte Level
This machine has two maintenance free batteries. They never require the addition to water.
When the charge indicator becomes transparency, it means low electrolyte state because of the leakage or charging system error. Determine the cause of problem and replace the batteries immediately.
Check Charging State
Check charging state through the charging indicator.
• GREEN: Sufficiently charged.
• BLACK: Insufficient charged.
• TRANSPARENT: Replace battery.

Check the Battery Terminals
Be certain that the battery is held securely in its compartment. Clean the battery terminals and the battery cable connectors. A solution of baking soda and water will neutralize acid on the battery surface, terminals, and cable connectors. Petroleum jelly or grease can be applied to the connectors to help prevent corrosion.
