WARNING
Sulfuric acid in batteries.
Can cause severe injury or death.
Use protective goggles and clothes. Can cause
permanent damage to eyes, burn skin, and eat holes
in clothing.
Sulfuric acid in batteries can cause severe injury or
death. Sulfuric acid in battery can cause permanent
damage to eyes, burn skin, and eat holes in clothing.
Always wear splash-proof safety goggles when working
around the battery. If battery electrolyte is splashed in
the eyes or on skin, immediately flush the affected area
for 15 minutes with large quantities of clean water. In the
case of eye contact, seek immediate medical aid. Never
add acid to a battery once the battery has been placed in
service. Doing so may result in hazardous spattering of
electrolyte.
WARNING
Hazardous voltage.
Do not operate generator set without all guards
and electrical enclosures in place.
Moving rotor.
Can cause severe injury or death.
Hazardous voltage can cause severe injury or
death. Electrical shock may occur if battery charger is
not properly grounded. Connect battery charger
enclosure to ground of a permanent wiring system. As
an alternative, run an equipment-grounding conductor
with circuit conductors and connect to
equipment-grounding terminal or lead on battery
charger. Battery charger installation should be
performed as prescribed in equipment manual and must
comply with all local codes and ordinances.
(Applies to Optional Battery Charger.)
WARNING
Explosion.
Can cause severe injury or death. Relays in
battery charger cause arcs or sparks.
Locate in a well ventilated area. Keep explosive
fumes away.
Explosion can cause severe injury or death. Battery
gases can cause an explosion. Do not smoke or permit
flame or spark to occur near a battery at any time,
particularly when it is being charged. Avoid contacting
terminals with tools, etc. to prevent burns and to prevent
sparks that could cause an explosion. Remove
wristwatch, rings, and any other jewelry before handling
battery. Never connect negative (–) battery cable to
positive (+) connection terminal of starter solenoid. Do
not test battery condition by shorting terminals together
or sparks could ignite battery gases or fuel vapors. Any
compartment containing batteries must be well
ventilated to prevent accumulation of explosive gases.
To avoid sparks, do not disturb battery charger
connections while battery is being charged and always
turn charger off before disconnecting battery
connections. When disconnecting battery, remove
negative lead first and reconnect it last.
Charge 6- or 12-cell lead-acid batteries according to the
following procedure.
1. Inspect battery for defective cables, loose posts,
or loose terminals. Battery terminals and battery
charger clips must be tight and cleaned of all
corrosion for efficient charging.
2. Check the fluid level in each cell. If fluid level is low,
add distilled water until fluid is at proper level. (No
maintenance is required for sealed batteries.)
When using a dry-charge battery, the battery must
be given a conditioning charge immediately after
the electrolyte fluid has been added. An automatic
charger will not operate properly on this type of
battery unless it has been given a conditioning
charge. Follow the battery manufacturer’s
recommendations for length of charge.
