Cold Weather Starting
1. Engage the park brake. (Figure 4-2)
2. Insert key into the ignition and turn clockwise to
the START position. (The “Wait to Start” light will
illuminate for a few seconds on the steering control
panel). AFTER the Wait to Start light disappears,
turn key to the ON position to crank engine.
3. Allow the engine to idle about ten minutes before
driving the machine.
Stopping the Engine
Before leaving the operator station,
place the machine in neutral, lower the moldboard
(and any other attachments) to the ground, and apply
the park brake.
1. Lower all attachments to the ground.
2. Apply park brake.
3. Turn ignition key counterclockwise to the OFF
position and remove key.
NOTE: The electrical system will continue to
operate for approximately 20 seconds after
the ignition is turned off. This allows the
engine ECU (Engine Control Unit) to store
critical engine data as it powers down.
NOTE: You may also hear a slight noise for a few
seconds after turning off the engine. This
is the DEF (Diesel Exhaust Fluid) system
automatically purging.
Emergency Stop Button
The purpose of the Emergency Stop Button (E-Stop)
is to shut down the engine and all machine functions in
an emergency situation. This additional safety feature
should only be used if the operator needs to shut down
all machine operations quickly. (Figure 4-2)
ALWAYS wear your seat belt! If you
engage the E-Stop button, the grader will stop very
quickly and could result in serious injury if you are
not wearing seat belt securely.
