SECTION C
Operating and Maintenance
Preparation for Starting
Check the radiator water level.
Check the engine sump oil level.
See that there is fuel oil in the tank.
Check that the starter battery is fully charged and that
all electrical connections are properly made and all
circuits in order.
Starting the Engine
If the engine is warm, turn starter switch in a
clockwise direction to the "HS" position (see Fig. C.1).
As soon as the engine starts. release the switch to the
"R" position.
Be sure that the starter pinion and engine have
stopped rotating before re-engaging the starter motor,
otherwise damage may result.

If weather is cold, turn starter switch to the "H" position
(see Fig. C.1) and hold it there for fifteen to twenty
seconds.
Then turn the starter switch to the "HS" position, thereby
engaging the starter motor.
If the engine does not start after twenty seconds,
return the switch to the "H" position for ten seconds and
then re-engage the starter motor by switching to the
"HS" position.
As soon at the engine starts, release the switch to the
"R" position.
Earlier Heat Start Switch
The cold start switch supplied with earlier engines is
shown in Fig. C.2.
With this type of switch, starting a warm engine is
effected by turning the switch in a clockwise direction to
the "S" position.
In cold weather, the switch should be turned to the "H"
position for fifteen to twenty seconds and then to the
"HS" position in order to engage the starter motor.
As soon as the engine starts, the switch should be
returned to the "0" position.
When this type of switch is used, it was sometimes
customary to have a separate switch for the electrical
circuits and this should be turned on before starting the
engine and turned off after stopping the engine.
Starting the Engine (Alternative Method)
With some engines. a different starter switch may be
found and the cold start aid operated by means of a
separate push button switch.
