5. Oil-pressure gauge diesel engine
When starting this gauge will read approx. 5 bar. As soon as the oil of the diesel engine is warmed
up it will read approx. 3 bar.
6. Fuel gauge
This gauge only functions when the ignition is switched on.
7. Coolant temperature gauge
On this gauge you can read the coolant temperature. In the diesel engine safety system an
overheating sensor is built-in. As soon as the temperature exceeds 110 °C, it activates the horn.
Also the Indicator light “oil pressure” (15) will light up. The engine must be switched off immediately.
10. Warning lamp charging voltage batteries
If the charging voltage of the batteries is too low, this indicator lamp will light up.
12. Warning lamp air-pressure
If the air-pressure in brake circuit 1 or 2 is below 5.5 bar, this indicator lamp will light up. The crane
can and must not be driven. If this lamp is on after starting the engine, leave the engine running at
idling speed until the air-pressure is 5.5 bar. The lamp will go out.
14. Indicator lamp pre-heating diesel engine
This lamp lights up when pre-heating the diesel engine. The light remains on while holding the

36. Oil pressure suspension and outriggers
This lamp goes on and a buzzer sounds at the rear outriggers as soon as the pressure in the
outrigger/suspension system becomes too high, due to the fact, that the outriggers, axles or
outrigger beams are blocked while extending or retracting the cylinders.
During levelling operation and when moving the axles up or down, this light could also go on. This
does not present a problem.
If no outrigger/suspension function is operated, the lamp indicates a malfunction.
37. Switch all axles in/out
With this switch the cylinders of all axles are moved in and out simultaneously (e.g. when
supporting the crane on outriggers).
38. Switch axle 1 in/out
With this switch the cylinders of axle 1 are moved in and out.
39. Switch axles 2 and 3 left side in/out
With this switch the cylinders on the left side of axles 2 and 3 are moved in and out.
40. Switch axles 2 and 3 right side in/out
