STARTING AND STOPPING DIESEL ENGINE
Before starting the engine, make certain all
points of service and lubrication have been
checked.
Check the radiatoT for coolant and
crankcas e for oil level ..
Place range selector in the neutral
position~
Turn the key switch to the
HONI!
position and
depress starting button to crank engine.
CraILlt
engine 15 seconds to assure proper lubrication
of engine cornponents before engine is started.
Place throttle lever in a position to give 900 to
1000 RPM.
Pull out On fuel pump knob, located
on dash.
Depress starter button.. If engine does
not start in 30 seconds, allow starter to cool 2
minutes before engine is
started~
In cooler telnperatures use of the manifold air
heater will aid in starting.
Use of the air heater
should be started when temperatures drop below
60 o F.
To operate the manifold air heater, turn
the key switch past the ((ONt! position and hold
for approxirrately one lmnute to allow the heating
element to become hot.
Then depress starting
switch to crank
engine~
If
the temperature is near freezing
1
it rnay be
necessary to depress the air heater switch while
the engine is cranking.
Do
not crank the engine
over five or six seconds if it does not attempt to
start. Allow starter to cool between each inter-
val, while continuing with use of air heater.
If cranking speed increases after five to six
seconds of cranking, which indicates engine is
attempting to start, continue with use of air
heater and crank until engine starts.
Check the
heating elelTIent to see if it is working properly.
The battery ITlUst be kept in a full charged condi-
tion.
After the engine has started, keep at 900 to 1000
RP1vl and allow engine to run until temperature
reaches l200F. before placing a load on the
tractor~
Check oil pressure when e..YJ.gine starts.
In extremely cold temperatures, an ether starting
aid is available as optional equipment and can be
used to obtain quick starts in all temperatures.
The starting aid discharges metered amounts of
a low combustible starting fluid into intake air
stream, thus obtaining a lower ignition point
than diesel fuel; thereiore
1
eliminating unneces-
sary wear to starting motor and batteries ..
(t
.
CAUTIO)l:
When us
ether starting
~
aid~
do not use the air
heater~
as there is
' .
danger of igniting the ether vapor in intake
manifold.
There is a possibility of damage to the
dry type air filter element.
VVhen using starting
fluid. crank engine until smoke rises from ex-
haust stack, indicating diesel fuel is being in-
jected, before injecting starting fluid.
After engine starts, run at approximately 1000
RPM.
Check to see that engine oil pressure
light goes out after
has started.
Should
27
light continue to glow, stop engine, determine
and correct cause.
Fast Warm-Up Period
Condensation accumulates in any engine during
initial warm-up peTiod
Or
when operating at too
Iowa temperatuTe..
Reduce condensation and
undue engine wear - practice fast warm-up of
engine temperature.
""'gme is equipped with a thennostat by-pass
system to provide fast
warm-up~
This warm-up
peried
can
be further reduced by operating engine
at approximately 1000 RPM and slightly loading
engine for first five to ten minutes, such as
driving to field in third gear.
Never operate the
tractor under full load until the engine b,s reached
operating temperature.
Avoid unnecessary idling of the engine, as this
will cause engine operating temperature to fall
below its normal operating range and cause rapid
accurrulation of engine sludge. Irlling also causes
engirle oil dilution due to incomplete fuel burning
as well as forming deposits on valves and piston
rings. It is best to stop engine
if
tractor is to be
idling for a time.
Stopping The Engine
Never shut off a hot engine. Allow it to idle for a
couple
of
minutes.
This gives engine a chance to
cool gradually.
Now shut off engine by pushing
fuel injection shut-off control knob in.
DIESEL STARTING FLUID
Starting fluid must not be injected into the air
cleaner intake stack on tractors equipped '\vith a
dry type air cleaner.
This is not practical as
it requires an excessive amount of starting fluid
and provides a means of burning the air clea.'Yler
element if the air heater is accidently or pur-
pos
ely
used~
Never use the engine air heater and
fluid
at th.e
Satre
time.
Never use starting fluid
the engine is cranking. If starting fluld has been
used, do not use the air heater until engine has
been purged of all starting fluid.
If the air
heater has been used, crank engine for 15 seoon.ds
without use of air heater before using starting
fluid.
1£
it
is desired to use starting fluid, it should
be used in conjunction with the diesel engine
starting aid which is available as optional mis-
cellaneous equipment.
This starting aid injects
metered amounts of starting fluid through a
nozzle into the intake air stream of the intake
manifold,
Failure to follow the above instructions and pre-
cautions can cause ignition of starting fluid in
the intake manifold or air cleaner element.
This
burns the element to destruction and allows dirt
to be -drawn into the engine.
