3.6 Cooling S ystem
The engine fan draws cooling air through the openings
in the sides and end near the battery. The alternator fan
draws cooling air through openings on the side walls of
the enclosure. The cooling air mixes with the engine
exhaust and is discharged at the exhaust outlet. See
Figure 3-5. 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.

3.7 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
(exhaust manifold, exhaust line, flexible exhaust,
clamps, silencer, and outlet pipe) for cracks, leaks, and
corrosion.
D Check for corroded or broken metal parts and replace
them as needed.
D Check for loose, corroded, or missing clamps and
hangers. Tighten or replace clamps and/or hangers
as needed.
D Check for and remove loose insulation in the exhaust
duct.
D Check that the exhaust outlet is clear.
3.8 Battery
Sulfuric acid in batteries.
Can cause severe injury or death.
Wear protective goggles and clothing.
Battery acid may cause blindness and
burn skin.
WARNING
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 batteryafter 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 ischarging. Do not dispose of a battery ina
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.
