FIGURE 4.5 Locks of load box walls and wall extensions
(1) left wall locking lever, (2) rear wall locking lever, (3) side wall lock (rear left), (4) rear wall
lock (left), (5) wall extension lug
If a second trailer is hitched, it should be unloaded only when the load box of the first trailer
has been lowered and the hydraulic tipping system control lever is placed in position 2 --
tipping of the second trailer.
DANGER
Incorrectly secured tipping pins may cause serious damage to the trailer.
When opening the load box side wall locks take particular care because of the pressure
applied by the load to the walls.
When using the trailer with extra wall extensions, pay attention to the stability and
possible tipping over the trailer, monitor trailer body movements on uneven ground.
When unloading, make certain that there is nobody near the load box.
To prevent injury, use protective gloves when opening/closing the wall bolts and locks.
