Engine Temperature; Engine Oil Pressure; Electrical - MacDon M105 Operator's Manual

Engine Temperature

The normal engine operating temperature range is
180–225°F (82–107°C).
If the temperature exceeds 230°F (110°C), an ongoing
intermittent tone will be heard and the cab display module
(CDM) (A) will flash "ENGINE TEMP". Stop the engine
immediately and determine cause. The tone will stop and
the CDM (A) will return to normal when the temperature
drops below 225°F (107°C).

Engine Oil Pressure

The nominal engine oil pressure is 10 psi (69 kPa) at low idle and 55.1 psi (380 kPa) at maximum rated speed.
If the oil pressure drops below the preset level of 7.5 psi (52 kPa), the cab display module (CDM) flashes an error
code and error message.
If the STOP ENGINE light illuminates, stop the engine IMMEDIATELY and investigate.
If the yellow CAUTION light illuminates, stopping immediately is optional. You may continue operations and
investigate later, but you are STRONGLY advised to monitor the situation carefully.

Electrical

The electrical system voltage is displayed on the cab display module (CDM) when selected with the SELECT
button on the ground speed lever (GSL) handle or the SELECT switch on the CDM. The display indicates the
condition of the battery and alternator.
