"Lifting and tilting limitation" assistance
function
The "lifting and tilting limitation" assistance
function reduces the lifting and tilting speed
in critical situations that could lead to the
truck tipping over. For a standard lift mast, the
assistance function is active above a preset
lift height (between 1.80 m and 2.20 m). For
duplex or triplex lift masts, the assistance
function is active above the first stage of the lift
mast.
NOTE
If the truck is switched off immediately after
the assistance function has intervened (switch
key turned to the zero position, emergency
off switch actuated), the load-dependant
assistance system can fail when the truck is
switched back on. Therefore, after switching
the truck on, perform a lifting procedure
