Chapter 7 – Prestart 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.
4. Test the platform foot valve by moving a boom
function control without stepping on the foot valve.
If movement occurs the interlock is not functioning
properly. Do not operate the machine until the prob-
lem is corrected.
5. Test the operation of each control in both directions
from the upper controls.
6. The drive range switch and maximum travel speeds
are interlocked through limit switches on the riser
and the main boom that senses the position of the
booms.
• When the main boom is raised approximately 1 ½"
(3.8 cm) or extended approximately 1" (2.5 cm),
the machine should travel in low speed only.
• To operate in high speed the booms must be
stowed.
