– shift into D position,
– Release the parking and service brakes,

– Do not apply the accelerator if you wish to brake with the engine.

If the truck crane starts to move forwards in neutral position you can still
switch to position D. A gear appropriate to the speed is engaged and the
engine brake power is effective.
To start reversing you must do the following:
– Shift into R position,
– apply the parking brake,
– press the accelerator,
– release the parking brake after the clutch has engaged.

Risk of accidents when driving in neutral position!
Never switch into neutral position whilst driving.
In neutral position, the truck crane may accelerate and the engine retarder
is ineffective.
G
Danger when starting to reverse!
When starting to reverse, always keep the truck crane stationary with the
parking brake until the transmission clutch is engaged. If the truck crane
starts to roll away before this (when changing from brake pedal to acceler-
ator), no gear will be engaged, and you can stop the truck crane only by
braking.
