Electrical System Hazards
Before working on the electrical system, disconnect the
battery cable(s).
— Remove the battery negative (-) cable(s) first.
— When reconnecting the battery, connect the battery
negative (-) cable(s) last.
Battery electrolyte contains acid, which is a POISON
and can cause SEVERE CHEMICAL BURNS.
Avoid Injury
— Wear a face shield to prevent electrolyte contact with
your eyes.
— Wear chemical-resistant gloves and clothing to keep
electrolyte off your skin and regular clothing.
WARNING! Electrolyte will damage eyes or skin on
contact. Always wear a face shield to avoid getting
electrolyte in eyes. If electrolyte contacts eyes, flush
immediately with clean water and get medical attention.
Wear rubber gloves and protective clothing to keep
electrolyte off skin.
If electrolyte contacts exposed skin
or clothing, wash off immediately with clean water.
If electrolyte is ingested, seek MEDICAL ATTENTION
IMMEDIATELY. NEVER give fluids that would induce
vomiting.

Avoid Battery Explosion
WARNING! Avoid possible death or serious injury from
explosion. Lead-acid batteries produce extremely
explosive gases, especially when being charged.
Keep
arcs, sparks, flames and lighted tobacco away.
— Do not smoke near batteries.
— Check battery cables for worn or damaged insulation.
— Keep arcs, sparks and open flames away from
batteries.
— Provide adequate ventilation.
Never check the battery by placing a metal object
across the battery posts; the resulting spark could
cause an explosion.
WARNING! Avoid possible death or serious injury from
battery explosion. Do not charge a battery or boost-
start the engine if the battery is frozen. Warm to 60°F
(15.5°C) or the battery may explode.
Safety rules during battery boost-starting:
— Follow the instructions for proper “battery boost-
starting” as specified in the manufacturer’s manual.
— Be sure the machines are not touching.
— Observe the polarity of the batteries and connections.
— Make the final cable connection to the engine or the
ground point farthest from the battery and away from
fuel lines. Never make the final connection at the
starter or dead battery—sparks may ignite the
explosive gases present at the battery.
— When disconnecting cables after boost-starting,
remove the cables in reverse order of connection
(i.e., final connection first).
