CAUTION
Due to the higher viscosity in the hydraulic system and the engine oil circuit at temperatures below 0 °C,
severe damage may be caused if the speed is increased immediately.
Allow the engine to run at low speed for some time at temperatures below 0 °C.
The lower the outside temperatures, the longer the warm-up phases.
Under no circumstances should the engine be started by towing the wheel loader! The hydraulic system may be
damaged!
If the warning lights do not go out while the engine is running, stop the engine immediately.
Ensure that the fault is rectified immediately! Do not use the wheel loader before the fault has been rectified!
Do not stop the engine suddenly from full load, but allow it to idle for 3 more minutes to equalize the temperature
before you turn off the engine.
Description of starting procedure
Start the wheel loader's engine using the ignition key.
1. Press the foot gas pedal.
2. Starting:
- Insert the key – position 0 = no operating voltage.
- Turn the key anti-clockwise against the spring pressure until the preheat
monitor lamp lights up
Position -1 = preheating (the preheater lamp indicates preheating)
- Turn the key further clockwise against the spring pressure – position 2 = start
(it should be noted that on wheel loaders with a 2-stage drive, the red button
for drive position selection must protrude).
- Release the key as soon as the engine starts – the key returns to position 1 –
indicator lamps extinguish
3. Check that all indicator lamps have extinguished and rectify any defects before
moving off with the wheel loader.
If the engine doesn't start
CAUTION
It is not possible to start the engine by towing the wheel loader. The hydraulic system may be damaged!
• Attempt to start no more than 20 seconds continuously
• Wait one minute.
• Repeat the starting process.
• If the engine does not start after two attempts, find the cause by referring to the fault table ("Fault finding and
troubleshooting") or contact a specialist workshop.
