NO L O A D O P E R A T I O N
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 T E M P E R A T U R E S
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.
O U T - O F - S E R V I C E P R O T E C T I O N
For storage periods of all durations, refer to Allis-
Chalmers manual.
LOW T E M P E R A T U R E S
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 A L T I T U D E
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.
