Passengers must not try to force open the

• Check that the operang condions of the main brake and
winch are safe for moving the cab.
To see if the main brake on the winch is
working properly, check:
- if the brake shoes are broken
- if the brake linings are damaged which
limits the contact surface
- if contact with the braking surface is uniform
• Check rotaon direcon of the winch for the cab movement
manoeuvre.
If the winch and/or the main brake are out
of use or the safety is inserted, perform the
rescue procedure and ensure that the cab
is secure by using a special device suitable
for the type of plant, place and operang
condions.
• Manually block rotaon of the winch's ywheel.
• Release the main brake using the special manual lever (POS 2).
• Begin manual operang to move the cab to the required oor by
manually rotang the ywheel in the right direcon.
• Release the manual release lever of the main brake on the winch
and check that it goes back to the o posion (POS 1).
• Open the cabin doors and help the passengers.
• Close the cabin and oor doors.
