switch of the Emergency limit switch before the drive pinion leaves the

control to the right and hold in this position.
Then press the button
UP
(3). - Now the
load platform will move downwards out of
the EMERGENCY LIMIT position.
• Release the key switch (1).

−
the brake's air gap is too large,
−
The

−
The platform has been lowered with the manual brake release.
