Fit the ramps by slotting them into the platforms on the
required end and then fix the wheel stops on the opposite.
4.8 ADJUSTING THE LIFTING CABLES
Drive a vehicle onto the lift.
Raise the lift to the maximum height and check if the four
wedges are fitted inside the slots of the safety rods.
Check if the distance between the wedges and the slots of
the safety rods on the 4 posts is at least 20 mm from the
support; a lower value would not allow the safety device to
rotate, and it would stay attached to the rod.
If necessary, level the unit by adjusting the nuts on the
terminals of the cables and the limit micro switch.
When the adjustment is completed, lock with the lock nuts.
IMPORTANT: This adjustment must be repeated 1 or 2
weeks after setting up the lift.
