COMBINATION DISPLAY INSTRUMENT
72 Operating manual T225 / T230
Motor oil pressure
Fig. 62: Warning light “Motor oil pressure”
The warning light is on the combination display instrument.
This warning light lights up during ignition. This warning light
should go out once the engine has started up.
If the warning light does not go out after the engine has
started, or if it relights, then the oil pressure of the lubrication
system is insufficient. The engine shuts off automatically.
Too little oil pressure leads to engine damage. Have
the cause of the problem determined immediately. For
help see “Displays of the combination display
instrument” on page 125.
Press the “Bypassing the safety switch-off” button in
order to move the MT out of the danger zone in the
case of an emergency, see “Bypassing the engine's
safety switch-off” on page 54.
Malfunction of air reserve pressure
Fig. 63: Warning light “Malfunction of air reserve pressure”
The warning light is on the combination display instrument.
This warning light is on if the air pressure level in the air
reserve tanks is below 5.2 bar. If the air pressure in the air
reserve tanks is too low, then the brakes on the MT and the
semi-trailer do not function properly. That means, do not move
the MT as long as the warning light is lit.
Let the engine run at a medium speed until the warning light
goes out.
If the warning light does not go out, determine the
cause of the problem immediately. For help see
“Displays of the combination display instrument” on
page 125.
