4 - Safety functional checks
To protect the user and the machine, safety systems prevent the movement of the machine beyond its
operating limits. These safety systems when activated immobilize the machine and prevent further
movement.
The operator must be familiar with this technology and understand that is not a malfunction but an
indication that the machine has reached an operation limit.
Aerial Work platforms are equipped with two control boxes which allow operators to safely use the
machine. An auxiliary device (T-handle) is available on the chassis to assist with the emergency
lowering of the machine. Each control box is equipped with an E-Stop button, which cuts all movements
when pushed in.
The following checks describe the operation of the machine and the specific controls required.
The speed selector buttons at the ground control box and the platform control box act as the enable
switch.
For the location and description of these controls : refer to section B 3.3 and D 2 Ground control
box and B 3.4 and D 3 Platform control box.
