mechanical safety devices
• undo cap T of solenoid valve YVD;
• turn the brass screw B on solenoid valve YVD anticlockwise
• turn the cursors of the hydraulic solenoid valves
YVB1 and YVB2 with an open ended wrench, adjusting one valve then the other in alter-
nate small steps to minimise the misalignment between the runways
• once the lift is in the lowest position, restore the original operating conditions
(turn the brass screws on solenoid valve YVD completely clockwise and re-tighten the
cap T on the solenoid valve, then turn screw A on solenoid valve YVA anticlockwise)
Warning
Never interrupt an incomplete manual emergency manoeuvre as the lift runways may
become slowly misaligned. If necessary, stop or cancel the manual emergency manoeuvre.
