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.
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.
6. Test the platform foot switch by moving a boom
function control without stepping on the foot switch.
If movement occurs the interlock is not functioning
properly. Do not operate the machine until the prob-
lem is corrected.
7. Test the operation of each control in both directions
from the upper controls.
8. The drive range switch and maximum travel speeds
are interlocked through a limit switch on the main
boom that senses the position of the booms.
• When the main boom is raised a few degrees above
horizontal or extended approximately 6½″ (6.5
cm), the machine should travel in low speed only.
• To operate in high speed the booms must be
stowed.
