Do an emergency discharge
• Switch off the main switch and secure against re-
start (shut down).
• Loosen and remove all unit covers.
• For safety reasons, block off the endangered
area and the lift leaving ample room.
• Loosen and remove 2 counter nuts (spanner
width 41) at the upper end of the lift rails in the di-
rection of the arrow. This procedure must be done
on all lift rails.

• The piston rods can jam in the upper bore of the
lift rail when they are limited by any contamina-
tion deposits. To loosen these connections, we
recommend a commercially available solvent
and simultaneous lubricant (e.g. WD40). Spray
this penetrating spray generously between the
thread and bore. The treatment time depends on
the degree of contamination.

steps of 5-10 cm until the entire lift has reached
the lowest position.
