Cleaning Battery; Battery Charger - Kohler 8.5RES Service

Battery electrolyte is a diluted sulfuric acid. Battery acid
can cause severe injury or death. Battery acid can cause
blindness and burn skin. Always wear splashproof safety
goggles, rubber gloves, and boots when servicing the battery.
Do not open a sealed battery or mutilate the battery case. If
battery acid splashes in the eyes or on the skin, immediately
flush the affected area for 15 minutes with large quantities of
clean water. Seek immediate medical aid in the case of eye
contact. Never add acid to a battery after placing the battery in
service, as this may result in hazardous spattering of battery
acid.
Battery acid cleanup. Battery acid can cause severe
injury or death. Battery acid is electrically conductive and
corrosive. Add 500 g (1 lb.) of bicarbonate of soda (baking
soda) to a container with 4 L (1 gal.) of water and mix the
neutralizing solution. Pour the neutralizing solution on the
spilled battery acid and continue to add the neutralizing
solution to the spilled battery acid until all evidence of a
chemical reaction (foaming) has ceased. Flush the resulting
liquid with water and dry the area.
Battery gases. Explosion can cause severe injury or
death. Battery gases can cause an explosion. Do not smoke
or permit flames or sparks to occur near a battery at any time,
particularly when it is charging. Do not dispose of a battery in a
fire. To prevent burns and sparks that could cause an
explosion, avoid touching the battery terminals with tools or
other metal objects. Remove all jewelry before servicing the
equipment. Discharge static electricity from your body before
touching batteries by first touching a grounded metal surface
away from the battery. To avoid sparks, do not disturb the
battery charger connections while the battery is charging.
Always turn the battery charger off before disconnecting the
battery connections. Ventilate the compartments containing
batteries to prevent accumulation of explosive gases.
Battery short circuits. Explosion can cause severe injury
or death. Short circuits can cause bodily injury and/or
equipment damage. Disconnect the battery before generator
set installation or maintenance. Remove all jewelry before
servicing the equipment. Use tools with insulated handles.
Remove the negative (--) lead first when disconnecting the
battery. Reconnect the negative (--) lead last when
reconnecting the battery. Never connect the negative (--)
battery cable to the positive (+) connection terminal of the
starter solenoid. Do not test the battery condition by shorting
the terminals together.
Use a 12-volt battery with a minimum rating of 525 cold
cranking amps at --18_C (0_F) The generator set uses a
negative ground with a 12-volt engine electrical system.
Make sure that the battery is correctly connected and
the terminals are tight. See Figure 2-12.
Note: The generator set will not start and circuit board
damage may result if the battery is connected in
reverse.

Clean the battery and cables and tighten battery
terminals using the service schedule recommendations.
Clean the battery by wiping it with a damp cloth. Keep
the electrical connections dry and tight.
Consult the battery manufacturer's instructions for
battery care and maintenance.

Cleaning Battery

To prevent dirt and grime buildup, occasionally wipe the
battery with a damp cloth.
To prevent corrosion, maintain tight, dry electrical
connections at the battery terminals.
corrosion from battery terminals, disconnect the cables
from the battery and scrub the terminals with a wire
brush. Clean the battery and cables with a solution of
baking soda and water. Do not allow the cleaning
solution to enter the battery's cells. After cleaning, flush
the battery and cables with clean water and wipe them
with a dry, lint-free cloth.
After reconnecting the battery cables, coat the battery
terminals with petroleum jelly, silicone grease, or other
nonconductive grease.
2.7.2

Battery Charger

Generator sets are equipped with a factory-installed
battery charger to keep the starting battery fully
charged. Observe the battery polarity when connecting
the battery charger. Check the battery charger fuse and
power supply.
See the generator set operation manual for information
about battery charger operation and troubleshooting.
