AUTOMATIC STARTING AND STOPPING
Optional controls may be used for automatic start
and stop, but must provide engine preheating.
The automatic control should have a time delay relay
to preheat glow plugs and the manifold heater for at
least
20
seconds before cranking occurs. The time
delay relay prevents immediate engagement of the
starter in case the load is reapplied before the engine
stops.
APPLYING LOAD
If practicable, allow engine to warm up before con-
necting a heavy load. Continuous overloading causes
high operating temperatures that can damage
the
engine. The exhaust system may form carbon depos-
its during operation at light loads; apply full load
occasionally before shut-down to prevent excessive
carbon accumulations.
Try to apply the load in steps instead of full load at
one time.
BREAK-IN
PROCEDURE
The unit should be run in the following sequence:
1.
One half hour at 112 load.
2. One half hour at
3/4
load.
3.
Full load.
Continuous running under one half load during the
first few hundred hours may result in poor piston ring
seating, causing higherthan normal oil consumption
and blowby.
Drain and replace the crankcase oil after
first
50
hours
of
opera-
tion; drain while the engine
is
still hot.
INSPECTION
Check for alignment of engine and load. Misalign-
ment will causeexcessive vibration and bearing wear.
Make a visual inspection of the entire installation.
Contact with rofafing rnachlnery
mighf cause serious personal injury
or
death. Stay clear
of
rofafing componenfs and
ensure fhaf profecfive shields and guards are in place
and secured before operafing machinery.
