SAFETY
DEVICES
In case of dangerously high coolant (water)
temperature or low oil pressure, the cutoff switch
stops the unit. After an emergency stop, investigate
and correct the cause. Press reset button before
restarting.
BREAK-IN
PROCEDURE
The unit should be run in the following sequence:
1.
One half hour at 1/2
load.
2.
One half hour at 3/4
load.
3. Full
load.
Continuous running under one half load during the
first few hundred hours usually results in poor piston
ring seating, causing higher than normal oil
con-
sumption and blowby.
Drain and replace the crankcase oil after 50 hours of operation;
drain while the engine is still hot.
EXERCISE
STANDBY
PLANTS
Infrequent use results in hard starting. Operate
standby sets at least 30 minutes each week. Run
longer if battery needs charging.
LOW
TEMPERATURES
1.
Use correct SAE No. oil for temperature
con-
ditions. Change oil only when engine is warm. If
an unexpected temperature drop causes an
emergency, move the set to a warm location or
apply heated air (never use open flame) external-
ly until oil flows freely.
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. Use additional preheat time before cranking.
Between 30°
F
and 55°
F
preheat for one minute;
below 30°F preheat for two minutes. At low
temperatures, if engine won't start after cranking •
one minute, repeat preheating step.
6. If freezing temperature is anticipated during
stopped periods and engine is not protected with
anti-freeze, drain radiator and engine block.
Attach warning tag to refill before operation.
HIGH
TEMPERATURES
1.
See that nothing obstructs air flow to and from
set.
2.
Be sure set location is properly ventilated.
3. Check level of battery electrolyte frequently and
add approved water when necessary to maintain
proper level.
4.
Keep cooling system clean, radiatorfilled and see
that fan belt tension is properly adjusted.
DUST
AND DIRT
1.
Keep set clean. Keep cooling fins free of dirt, etc.
2.
Service air cleaner as frequently as necessary.
3. Change crankcase oil every 50 operating hours.
4.
Keep oil and fuel in dust-tight containers.
5. Keep governor linkage clean.
HIGH
ALTITUDE
Maximum power will be reduced approximately 4
percent for each 1000 feet above sea level, after the
first 1000 feet.
ENGINE
RATINGS
Ratings apply to altitudes up to 1000 feet, standard
cooling,
normal ambients and with No. 2 Diesel
fuel.
Consult nearest Onan service center or factory for
operating characteristics under other conditions.
OUT-OF-SERVICE
PROTECTION
The natural lubricating qualities of No. 2 diesel fuel
should protect a diesel engine for at least 30-days
when unit is not in service. Toprotectasetthatwill be
out of service for more than 30 days, proceed as
follows:
1.
Run set until thoroughly warm; generator under
at least 50 percent
load.
2.
Shut down engine and drain oil base while still
warm.
Refill and attach a warning tag indicating
viscosity of oil used.
3. Remove injectors. Pour
1-ounce
of rust inhibitor
(or SAE #10 oil) into each cylinder. Crank engine
over several times. Install injectors.
4.
Service air cleaner.
5. Clean throttle and governor linkage and protect
by wrapping with a clean cloth.
6. Plug exhaust outlets to prevent entrance of
moisture, bugs, dirt, etc.
7. Clean and wipeentire unit. Coat parts susceptible
to rust with a light coat of grease or oil.
