A
Warning
The potential for an accident increases when operating
an aerial platform that is damaged or malfunctioning.
Death or serious injury can result from such accidents.
Do not operate the aerial platform if it is damaged or
malfunctioning.
6. Place the drive/boom selector switch in the boom
position.
7. 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.
8. Test the operation of each control in both directions
from the upper controls.
9. 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 2.4 m (8
′
) the
machine should travel in low speed only. To operate
in high speed the booms must be stowed.

gency power position and step on the platform foot switch
to operate the aerial platform from the upper controls us-
ing the emergency power system.

gate is closed.
Lanyard Anchors
There are two lanyard anchors below the upper control
panel (refer to Figure 7.20).
