SAFETY
precautionS on maintenance
Disconnect the battery wiring
Disconnect the battery wiring before working
on the electrical system or doing electric
welding. Disconnect the negative (–) battery
cable first. When reconnecting, connect the
negative (–) battery cable last.
Use caution when handling batteries
• Batteries contain sulfuric acid which will
damage the eyes or skin in case of
contact.
· If eye contact occurs, flush immediately
with clean water and get prompt medical
attention.
· If accidentally swallowed, drink large
quantities of water or milk and call a
physician immediately.
· If acid contacts skin or clothing, wash off
immediately with a lot of water.
• Wear protective goggle and gloves when
working with batteries.
• Batteries generate flammable hydrogen
gas which may explode. Keep away from
flame, sparks, fire or lighted cigarettes.
• When checking the level of the battery
fluid, use a flashlight.
• Be sure to stop the engine by turning off
the starter switch before inspecting or
handling the battery.
• Be careful not to let metal tools or any
metal objects come into contact with the
battery terminals and cause a short circuit.
• Loose battery terminals may result in
sparks. Be sure to fasten terminals tightly.
• Make sure the battery caps are tightened
securely.
• Do not charge a battery or jump-start the
engine if the battery is frozen; otherwise it
may explode. Warm the frozen battery to
15°C (60°F) before use.
• Do not use the battery when the fluid level
is below the lower level limit. Doing so will
hasten the deterioration of the internal
portions of the battery and shorten the
battery life. It also can cause rupturing
(explosion).
• Do not add the distilled water above the
upper level limit. Doing so could cause the
fluid to leak. This fluid can cause skin
damage if contacted, or can cause the
machine components to corrode.
• Use a dampened cloth to clean around the
fluid level line and check the fluid level. Do
not clean with a dry cloth; otherwise it
could cause static electricity to build up,
resulting in ignition or explosion.
