Note
If the machine has a GM engine, there will be a 7 to 10
second delay after starting the engine, before the throttle
will go to mid or high. Start the engine and wait 10 seconds
before proceeding with machine operation.
5. Let the engine warm to operating temperature.
6. Hold the ground operation switch upward.
Danger
Pinch points may exist between moving components.
Death or serious injury will result from becoming
trapped between components, buildings, structures,
or other obstacles. Make sure all personnel stand
clear of the aerial platform while performing the pre-
start inspection.
Warning
The potential for an accident increases when operat-
ing an aerial platform that is damaged or malfunction-
ing. Death or serious injury could result from such
accidents. Do not operate the aerial platform if it is
damaged or malfunctioning.
7. Test the operation of each function in both direc-
tions.
Note
When checking the turntable rotation function in the
counterclockwise direction, the turntable will rotate to-
ward you.
Emergency Stop
To test the emergency stop button from the lower
controls:
. Push the emergency stop button inward to turn off
electrical power.
2. Test the lower control functions to make sure they no
longer operate.
Emergency Power
To test the emergency power system from the lower
controls:
. Place the battery disconnect switch, the emergency
stop switch, and the start switch in the on position.
2. Hold the engine/emergency power switch down
and the ground operation switch upward to operate
the aerial platform from the lower controls using the
emergency power system.
Emergency Lowering
The main boom can be lowered in an emergency using
the emergency lowering knob. The emergency lowering
knob is at the base of the main boom lift cylinder.
To inspect foam filled tires and wheels:
. Check the wheel lug nuts to see that none are miss-
ing, damaged, or loose.
2. Carefully inspect for large holes or cuts where foam
is coming out of the tire.
3. Look for large imbedded objects, such as angle iron,
that can rip a tire open.
Note
Punctures caused by bolts, screws, or nails are not a
problem for foam filled tires.
Lower Control Station
With no personnel in the platform, test the operation of each
control from the lower controls (refer to Figure 7.2).
Figure 7.12 – Lower Controls
