FUNCTION CHECK
If delayed movement is detected in wire rope operation, lower platform to stowed
position, shut down machine, and have wire ropes inspected/serviced by a factory
trained service technician. Loose or misadjusted wire ropes could result in serious
injury or death.
Perform the Function Check as follows:
1. From the ground control panel with no load in the platform:
a. Ensure that all machine functions are disabled when the Emergency Stop
Button is pushed in.
b. Ensure all functions stop when the function switch is released.
c. Operate all functions and check all limiting and cut-out switches to ensure
proper operation.
All boom sections should extend/retract together at the same rate of speed.
Any difference would indicate delayed movement and loose wire ropes.
d. Ensure proper operation of the manual descent controls.
2. From the platform control console:
a. Ensure that the control console is firmly secured in the proper location.
b. Check that all guards protecting the switches or locks are in place.
c. Ensure that all machine functions are disabled when the Emergency Stop
Button is pushed in.
d. Ensure that all machine functions stop when the footswitch is released.
e. Operate all functions and ensure proper operation.
All boom sections should extend/retract together at the same rate of speed.
Any difference would indicate delayed movement and loose wire ropes.
3. With the platform in the stowed position:
a. Drive the machine on a grade, not to exceed the rated gradeability, and stop
to ensure the brakes hold.
b. Check the tilt indicator is illuminated to ensure proper operation.
4. Swing the boom over either of the rear tires and ensure that the Drive Orientation
indicator illuminates and the Drive Orientation Override switch must be used for
the drive function to operate.
5. With the machine positioned on a smooth, firm surface within the limits of the
maximum operating slope, elevate the boom above 11° of horizontal. Select high
speed drive mode. Carefully attempt to drive and ensure the drive speed is
reduced.
