2. Visually inspect the rail and toeboard welds for
cracks.
3. Visually check all bolts and nuts fastening the platform
in place. They must be present and not show any
signs of looseness.
4. Inspect the gravity gates to be sure they are present,
not damaged, and move freely.
Lanyard Anchors
There are two lanyard anchors below the upper control
panel (refer to Figure 8.16).
Figure 8.16 – Inside Rear of Platform
To inspect the lanyard anchors:
1. Visually inspect the lanyard anchors to make sure
they are in place and not deformed.
2. Look for visible cracks in the welds and at the weld
to parent material joints. A bright light may be used
to provide adequate visibility of the inspection area.
Operating Controls
Use the following procedure to operate the machine from
the upper controls:
1. Make sure the battery disconnect is plugged in.
2. At the lower controls, place the emergency stop
switch and the start switch in the on position.
4. At the upper controls, pull the emergency stop button
outward (refer to Figure 8.17).

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 interlock 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 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 limit switches on the riser and
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.
Emergency Stop
To test the emergency stop button from the upper con-
trols:
1. At the lower controls, turn the start switch to the on
position and place the control selector switch in the
upper control position.
