Operator Controls
Key / Start Switch
The Key / Start Switch:
• Turns the truck electrical system on and off.
• Connects and tests the warning indicator lights.
• Connects the starter motor circuit when engine is to be started.
The Key / Start Switch has three
positions.
When the key is in the vertical "OFF"
position, all truck electrical circuits are
off, and the key can be removed.
From the "OFF" position, the key can
be turned clockwise to the "START"
position, where the starter motor is
engaged and part of the truck electrical system is energized.
When the key is released from the "START" position, it automatically
returns to the "RUN" position, where the starter is disengaged and
the entire truck electrical system is on.
The key switch has a mechanical "anti-restart" feature, which
prevents the engine starter from being engaged and damaged if the
operator attempts to start the engine when it is already running. The
key switch cannot be turned to the "START" position from the "RUN"
position without returning the key to the "OFF" position. If the engine
stops running, the key switch must be turned to the "OFF" position
before it can be restarted.
Engine Stop
Run the engine at idling speed briefly before shutting it off. Turn the
key switch to the "OFF" position to shut the engine down.
Engine shutdown function
The N.S controller or instrument pod circuit board receives signals
from sensors in various locations and shuts down the truck when
coolant temperature(30 seconds alarm), transaxle fluid temperature
are excessive or engine oil pressure is low. Before shutting down the
truck, the instrument pod sounds alarm for 5 seconds and flashes
indicator lights. After shutdown, the truck may be restarted, but if the
fault condition persists, the truck is shut down again.
