A
Warning
The potential for an accident increases when oper-
ating an aerial platform that is damaged or mal-
functioning. Death or serious injury can 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 func-
tion control without stepping on the foot switch. If
movement occurs the interlock is not functioning prop-
erly. Do not operate the machine until the problem 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 turn-
table that senses the main boom position. When the
main boom is raised approximately 8
′

machine should travel in low speed only. To operate
in high speed the booms must be stowed.
