• Push the "LOWER" button
wering process.
• The 4 safety ratchets are pulled back electrically
and after approx. 1.5 sec, the lift starts to lower.
• An acoustic warning signal sounds during lowe-
ring until the floor is reached.
• Once the lift is at the lowest position, the vehicle
can be driven off the lift.

RFH rail height equalisation
Longer continuous operation of the wheel free lift
without ever reaching the lowest position can result
in asynchronous running of the drive in rails. In nor-
mal cases height equalisation resets after a longer
waiting time (cooling of the oil).
For a residual height difference proceed as follows:
• At the wheel free lift, move the RFH switch (14) to
"I".
• Push the "LOWER" button
both rails of the wheel free lift have reached the
lowest position.
• Wheel free lift is functioning normally.
5.10 Safety switch below the drive rails
The lift has a safety switch (4) fitted below the drive-
in rails used to monitor the cables. This triggers if,
• a cable breaks
• the lift moves onto an obstacle and the cable
loosens
• only one safety ratchet has a catch latched in
and the cable is loose.
The lift then remains in place with no functionality.
