Operator’s Station
Warning Lights, Buzzers, “Limp Home” and Automatic Shut-down Modes
The machine is equipped with a variety of warning lamps and (optional) buzzers that alert
the operator of improper operating conditions. All warnings are indicated via a light, while
some have an optional buzzer in addition. Extreme conditions that may cause severe damage
to the machine also trigger “limp home” or automatic shut-down modes. If “limp home”
mode is activated, the engine’s RPM will automatically be reduced and there is approximately
60 seconds of operation remaining before the engine shuts down. Use this time to turn off
the augers, lift the conditioner and drive off the ice surface. If the ECU detects a low oil
pressure condition, it will shut off the engine immediately.
