Starting and Stopping the
Engine
Important: The fuel system will automatically
bleed itself when any of the following situations
occur:
• Initial start up of a new machine.
• The engine has ceased running due to lack of fuel.
• Maintenance has been performed upon the fuel
system components.
1. Ensure that the parking brake is set. Remove your
foot from the traction pedal and ensure that it is in
neutral.
2. Move the throttle control to the mid-idle position.
3. Turn the ignition key to the Run position. The glow
indicator will light.
4. When the glow indicator dims, turn the ignition key
to the Start position. Release the key immediately
when the engine starts and allow it to return to the
Run position. Allow engine to warm up at mid
speed (without load), then move the throttle control
to the desired position.
Important: Do not run the starter motor
more than 15 seconds at a time or premature
starter failure may result. If the engine fails to
start after 15 seconds, turn the key to the Off
position, recheck the controls and procedures,
wait 15 additional seconds, and repeat the
starting procedure.
When the temperature is less than 20°F (-75C),
preheat glow plugs twice prior to initial cranking
attempt. The starter motor can be run for 30
seconds on then 60 seconds off for 2 attempts.
5. To stop the engine, move the throttle control
backward to the Slow position, move the PTO lever
to the Off position, set the parking brake, and rotate
the ignition key to Off. Remove the key from the
switch to prevent accidental starting.
