7.13. Emergency descent procedure
In the case of a system defect preventing operation of the platform, proceed to a manual
emergency descent. Follow the following instructions:
• Connect the emergency descent levers (1) in the threaded holes of the engine brakes (2).
• Push one of the levers to the MAXIMUM position. Keep this lever completely pushed.
• Carefully push the second lever to let the platform descend by gravity. Important! Alternate
the pressure on the second lever to avoid excessive descent speed. A speed greater than
85 ft/min (24 m/min) will trigger the emergency centrifugal brake, leading to the complete stop
of the unit.
∞ SEE SECTION 7.14 CENTRIFUGAL EMERGENCY BRAKE ACTIVATION, ON PAGE 60.
• When ground level is reached, evacuate the platform and contact a certified technician.
• Warning! The brake lever must never be used to lower the platform during operation. This
system is intended for emergency use only.
