To inspect the guardrail system:
1. Inspect all components of the guardrail system. Make
sure the rails and toeboards are all in place and free
of any damage or deformation.
2. Visually inspect the rail and toeboard welds for
cracks.
3. Visually inspect all bolts and nuts fastening the plat-
form in place. They must be present and not show
any signs of looseness.
4. Inspect the gate(s) to be sure they are present, are
not damaged, and move freely.
Lanyard Anchors
There are two lanyard anchors below the upper control
panel (refer to Figure 7.18).
To inspect the lanyard anchors:
1. Visually inspect the lanyard anchors to make sure
they are in place and are 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 and test the ma-
chine from the upper controls:
1. Turn the battery disconnect switch on.
2. At the lower controls, place the emergency stop
switch and the start switch in the on position. Place
the control selector switch in the upper control posi-
tion.
3. At the upper controls (refer to Figure 7.19), pull the
emergency stop button outward.

4. Turn the start switch on the front of the upper control
panel to start until the engine starts, then release it.
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 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.
