5.2.5 Starting
To start moving, you have to:
– Apply the parking brake,
– Step on the accelerator (starts clutching),
– Release the parking brake after coupling (motor sound changes).
Warning when starting
When the load during starting is so large that it would cause the clutch to
overheat, a warning buzzer sounds. The warning message CL is also dis-
played.
• In this case, remove your foot from the accelerator immediately and apply
the service brake.
• Switch to the neutral position N and leave the vehicle engine running until
the coupling has cooled down and CL is no longer shown on the display.
• Select a lower starting gear.
• Start to move again.
H
If you do not release the accelerator, the gear is engaged automatically
within a few seconds. This can cause the engine to be throttled, or the
wheels to spin.
Exception: Gears 1 and R are not engaged automatically. Be careful not to
allow the clutch to overheat.
G
Danger by unexpected rolling
Also apply the parking brake before starting on sloping ground. The gear
will only be engaged after you step on the accelerator. This can lead to the
truck crane starting to move (also backwards) while you are moving your
foot from the brake pedal to the accelerator.
S
Risk of clutch damage
Always release the accelerator when the CL warning is shown. The clutch
will become overheated and damaged if you do not stop the starting pro-
cedure.
