Key Switch
The key switch is used for the following functions:
NOTE:
When the key switch is turned to the OFF
position, the monitor display will remain on
for 15 seconds before shutting off.
•
HEAT – Turn the key switch to HEAT (1) and
release. The key switch returns to OFF. Use the
HEAT position to aid in starting a cold engine. If
the engine coolant temperature is below a preset
value, the preheat cycle begins. While in the
preheat cycle, the preheat icon is illuminated on the
monitor home screen and the engine glow plugs are
energized. When the glow plugs are heated for a set
period of time, the preheat cycle is complete. The
preheat icon is no longer illuminated and the engine
can be started.
•
OFF – When the key switch is turned to OFF (2),
the engine is shut down, power to the electrical
system is shut off, and the key can be removed or
inserted.
•
ON – The ON position (3) allows the engine to remain running (if already started). The electrical system is
energized when the key switch is turned to ON.
•
START – When the key switch is turned to START (4), the starter motor will turn on and engage the engine
flywheel. Release the key after the engine has started and the key switch will return to ON, allowing the
engine to run and maintain power to the electrical systems. See “Starting the Engine” on page 4-12.
Throttle Control Dial
The throttle control dial (5) is used to adjust engine speed. Turn the dial clockwise to increase engine speed, and
counterclockwise to decrease engine speed:
•
MIN (low idle): Turn the throttle control dial fully counterclockwise.
•
MAX (high idle): Turn the throttle control dial fully clockwise.
NOTICE!
Except in an emergency, never shut down the engine while it is running at high idle. Stopping
the engine at high idle could damage the machine or cause it to run improperly.
