D. Once the lift is in the lowest position, swing out the lifting arms to the
start position.
• Always lower the lift (lifting arms) into the lowest posi-

At the same time, lowering to the lowest position is re-
quired so safety equipment becomes active in case of
malfunction. (Put the capture hook into the latch).
• Move the vehicle out of the lift.
