NO
LOAD
OPERATION
Periods of no load operation should tie held to a
minimum.
If it is necessary to keep the engine running
for long periods of time when no electric output is
required,
best engine performance will be obtained
by connecting a "dummy" electrical
load.
Such a load
could consist of heater elements, etc.
HIGH
TEMPERATURES
1.
See that nothing obstructs air flow to-and-from
: the set.
2.
Keep cooling system clean. .
3. Use correct SAE No. oil for temperature
con-
ditions.
OUT-OF-SERVICE
PROTECTION
For storage periods of all durations, refer to Allis-
Chalmers manual.
LOW
TEMPERATURES
1.
Use correct SAE No. oil for temperature
con-
ditions. Change oil only when engine is warm.
2.
Use fresh
fuel.
Protect against moisture conden-
sation.
3. Keep fuel system clean and batteries in a well
charged condition.
4.
Partially restrict cool airflow but use
care
to avoid
overheating.
5. Gonnect water jacket heater when set. is not
running.
6. Refer to Allis-Chalmers manual for further infor-
mation.
Water Jacket Heater The function of'ttiis .optional
heater is to keep the engine warm enough to assure
starting under adverse-weather conditions. Connect
the heater to a source of power that will be on during
the time the engine is not
running.
Be
sure the voltage
rating is correct for the heater element rating.
HIGH
ALTITUDE
Ratings apply to altitudes up to 1000-feet (304.8m),
standard cooling, normal ambients and with No. 2
Diesel
fuel.
Consult factory or nearest authorized
Onan distributor for operating characteristics under
other conditions.
Engine horsepower loss Is approximately 3 percent for each IOOO-
feet (304.8m) of altitude above sea level for a naturally aspirated
engine. Use lower power requirement at high altitudes to prevent
i smoke, overfueling and high temperatures.
