Engine Starting Between 0°C and -32°C
(32°F and -25°F)
DO NOT SPRAY ETHER or other starting fluids into
the air intake. This diesel engine is equipped with an
electric air intake heater system to aid cold weather
starting and reduce white smoke. Do not spray ether
into the air inlet. It could contact the heater elements
and cause an explosion. Use ONLY the start-aid
system or immediate engine damage and personal
injury may result.
Inject starting aid (ether) only after initial start-up, until
the engine is running smoothly.
Wait approximately three seconds before each ether
Use ether for cold starting purposes only, as directed.
Use ether sparingly. Excessive ether without cranking
can cause piston and ring damage.
1. Follow Steps 1 through 7 of Engine Starting Above
0°C (32°F), in this section.
2. If start-aid indicator (1) comes on, wait until the
indicator turns off (approximately 30 seconds)
before attempting to start the engine.
3. When start-aid indicator (1) has turned off, hold
engine start switch in the START position to crank
4. If the engine does not start after 15 to 30 seconds
of cranking, release the engine start switch and
move it to the ON position to allow the intake air
heater to operate. Wait approximately 30 seconds
to allow the starting motor to cool and intake air to
heat before cranking the engine again. Repeat
Steps 2 through 4 until the engine starts.
NOTE: Do not use ether to help start the engine at
temperatures above -32°C (-25°F). At warmer
temperatures, ether reduces the amount of oxygen
available for combustion, which makes the engine
more difficult to start.
Do not keep the starting motor engaged for more than
60 seconds at a time. Wait 30 seconds to allow the
starting motor to cool and inlet air to heat before trying
again. If the engine does not start after three attempts,
determine the cause of the malfunction. Pumping the
accelerator pedal will not assist in starting the engine.
5. Release the engine start switch into the ON position
after the engine reaches 1000 rpm. If the engine
runs roughly, operate start-aid switch (3) manually
to inject ether sparingly until the engine is running
NOTE: The ECM will disengage the starter at 600
rpm. Holding the starter engaged after the engine has
started will not damage the starter.
Do not increase engine speed until the oil pressure
gauge indicates normal (between 250 and 450 kPa (30
and 70 psi)). The engine oil pressure indicator should
go off, and the oil pressure should raise within 15
seconds after the engine starts. If oil pressure is not
indicated on the gauge within 15 seconds, do not drive
the machine. Stop the engine, and report the problem
to Unit Maintenance. Do not operate the machine until
the problem has been corrected.
NOTE: Applying a light load will help the engine
reach normal operating temperature sooner. When
idling in cold weather, the ECM will increase the engine
speed to approximately 1000 to 1200 rpm. Do not race
the engine to speed warm-up.
