Press the “FOLD” (4) push-button
on the remote control. The plat-

releasing the arrestor hooks.
If the arrester hooks engage every

The linear lift lowers the
platform slowly of its own
accord.

open.
Shut the emergency lowering val-
ve.
The roll-off guard does not
rest cleanly on the ground

pletely on the ground
when the lift is lowered to
the ground.

justed correctly.
Finely adjust the platform seg-
ments to one another (see Sec-
tion 11.3, page 44).
The platform is not exactly
horizontal when it stops at
the embarkation / disem-
barkation level.
The micro-switches on the same si-
de as the hydraulic aggregate requi-
re adjustment.
Finely adjust the micro-switches
(see Section 11.7, page 51).
