Forced lever – checking correct functioning
On suspension struts with forced levers, the forced levers must be checked
for proper functioning when the suspension is switched on and off.
Risk of crushing when releasing the suspension locking system.
When the suspension is switched on, the wheels drop down suddenly.
Ensure that nobody is in close proximity to the wheels when you switch
on the suspension.
Risk of damage to the tyres.
Remove sharp-edged or pointed objects from below the wheels before
switching on the suspension.
In this way you prevent the tyres from bursting or being damaged when
the wheels come down.
