Preparation
• Loosen and remove the plastic part (T-piece) of
the operating lever (9) at both screws on the side.
• Loosen and remove the stainless steel cover of
the unit.
• After the lift has been set down into the latch then

moves freely again. Then tie back the latch using,
e.g. a cable tie.

the same time slowly pull the operating lever (9).
The lowering procedure begins immediately. Low-
ering speed can be varied by the lever position.
• The lowering process must be continuously ob-
served.
• Release the operating lever (9) to stop or if there
is a danger.

Moving onto an obstacle

If the lift moves onto an obstacle during lowering,
then it remains in position due to the mechanical re-
sistance. In this case, move the lift upwards by push-
ing the operating lever (9) o "LIFT" (17) on the op-
erating panel until the obstacle can be removed.
Afterwards the lift is in a normal work condition and
can continue to be operated as described in the
operating manual.
