8. Check the air cleaner base. Make sure it is
secure and not bent or damaged. Also check the
element cover for damage and fit. Replace all
damaged air cleaner components. Remove any
loose dirt or debris from the air cleaner base.
Wipe the base carefully so that no dirt drops into
the intake throat. Check the condition of the
rubber seal on the air cleaner stud and replace
the seal if necessary.
9. Reinstall the paper element, precleaner, element
cover, element cover nut, and the air cleaner
cover. Secure the cover with the cover knob.
10. Reconnect the AC power to the generator set.
11. Reconnect the generator set engine starting
battery, negative (–) lead last.
4.5 Cooling System
The engine fan draws cooling air through the openings
in the sides. The alternator fan draws cooling air
through an opening on the side wall of the enclosure.
The cooling air mixes with the engine exhaust and is
discharged at the exhaust outlet. See the service view
in Section 1.7 for air intake and exhaust locations. To
prevent generator set damage caused by overheating,
keep the housing cooling inlets and outlets clean and
unobstructed at all times.
Note: Do not block the generator set cooling air inlets
or mount other equipment above them.
Overheating and severe generator damage may
occur.
4.6 Exhaust System
Remove all combustible materials from the exhaust
location. Combustible materials include building
materials as well as natural surroundings. Keep dry
field grass, foliage, and combustible landscaping
material a minimum of 1.5 m (5 ft.) from the exhaust
outlet.
Periodically inspect the exhaust system components
for cracks, leaks, and corrosion.
Check for corroded or broken metal parts and
replace them as needed.
Check that the exhaust outlet is clear.
4.7 Engine Starting Battery
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.
WARNING
!
Sulfuric acid in batteries.
Can cause severe injury or death.
Wear protective goggles and
clothing. Battery acid may cause
blindness and burn skin.
