SET EXERCISING
Establish an exercise program if unit is not used for
long periods of time. Start and run unit, with a full load
connected if possible, for at least 30 minutes every
week. This exercise program will:
• Lubricate internal engine parts.
• Assure proper starting when set is needed.
• Remove moisture.
• Keep carburetor filled with fuel.
• Bring engine up to operating temperature.
• Recharge battery.
ELECTRICAL OUTPUT
The generator set's wiring provides for 120 volts, with
the total electrical load not to exceed 25 amperes.

HIGH OPERATING TEMPERATURES
1. See thatnothingobstructs air flow to and from the
set.
2. Keep cooling fins clean. Air housing should be
properly installed and undamaged.
3. Keep ignition timing properly adjusted.
LOW OPERATING TEMPERATURES
1. Use co; • :t SAE oil for temperature conditions.
Change oil only when engine is warm. If an
unexpected temperature drop causes an
emergency, move vehicle to a warm location.
2. Use fresh gasoline. Protect against moisture
condensation. Below 0° F (-18° C), adjust car¬
buretor main jet for a slightly richerfuel mixture.
3. Keep ignition system clean, properly adjusted
and batteries in a well charged condition.
4. Partially restrict cool airflow, but use care to avoid
overheating.
EXTREMELY DUSTY OR DIRTY
1. Keep unit clean. Keep cooling surfaces clean.
2. Service air cleaner as frequently as necessary.
3. Change crankcase oil every 50 operating hours.
4. Keep oil and gasoline in dust-tight containers.
5. Keep governor linkage clean.
6. Clean generator brushes, slip rings, and com¬
mutator:
do not
remove normal dark brown film.
Do
not
polish.
HIGH ALTITUDE OPERATION
For operation at altitudes of 2500 feet (775 m) above
sea level, close carburetor main jet adjustment slight¬
ly to maintain proper air-to-fuel ratio (refer to the
ADJUSTMENTS
section). Maximum power will be
reduced approximately four percent for each 1000
feet (310 m) above sea level after the first 1000 feet.
Do not use discharged air from blower scroll
for compartment heating. Poisonous gas
fumes may be present.
OUT-OF-SERVICE PROTECTION
Protect a generator set that will be out of service for
more than 30 days from damage caused by rust or
corrosion. Use the following procedure to properly
protect the set.
1. Run the generator set with at least a 50 percent
load until thoroughly warm (usually about 1
hour).
2. Turn off fuel supply and allow the engine to run
out of fuel. Also operate the choke manually as
the engine stops to help drain the carburetor
completely.
