Preparation and Inspection

Pre-Operation Inspection:
1. Inspect each of the SkySense tubes for dents, cracks, or other
damage.
2. Inspect each SkySense sensor for any damage to the hous-
ing or sensor.
To test the SkySense system:
1.
Ensure there are no obstructions within 10 feet around or
above the platform and the machine is on a smooth, firm
surface within the limits of the maximum operating slope.
2. From the platform control console, lift and lower the plat-
form.
3. Place a hand or object 6" to 12" above one of the sensors,
then lift up the platform. Platform movement should stop,
the LED indicator should be red, and the alarm should
sound. If the alarm is muted, the mute button light should
be red.
4.
Release the joystick and enable switch.
5. Place a hand or object 6" to 12" above one of the sensors.
Press the override button on the notification unit and lift the
platform. The platform should lift, the LED indicator should
5-24
be red, and the alarm should sound. If the alarm is muted,
the mute button light should be red.
6.
Remove hand or object from the sensor zone, then release
the joystick and enable switch. Lower the platform to
stowed.
7.
Lift the platform with no hand or object above the sensor.
The platform should lift without interruption.
8. Lower the platform to stowed.

Operation

SkySense slows a machine's drive speed to elevated drive speed
when it is a certain distance away from an object, known as the
"warning zone." If the machine continues to approach the object
and moves into the "stop zone," SkySense stops all machine func-
tions.
For proportional functions that are activated by the joystick, the
size of the warning zone varies based on the amount of joystick
activation. The stop zone always activates at the same distance
from the object regardless of the joystick's position.
SkySense is active during the following functions:
• Lift Up
• Drive Forward
• Drive Reverse
