Inspect the rotation bearing bolts to ensure that none
are missing, damaged, or loose.
Upper Control Station
Inspect the platform and upper controls only if all func-
tions operated properly from the lower controls.
Guardrail System
The guardrail system (refer to Figure 7.26) includes the
top rail, mid rail, toeboards and a gravity gate or optional
swinging gate.
Figure 7.26 – Guardrail System
Inspect all components of the guardrail system. The
rails and toeboards must all be in place and free of
any damage or deformation. Visually check the rail and
toeboard welds for cracks. All bolts and nuts fastening
the platform in place must be present and not show any
signs of looseness.
Inspect the gravity gate to be sure it is present, is not
damaged and moves freely.
Inspect the optional swinging gate to see that it swings
freely, closes firmly and is not deformed in any way.
Make sure the spring closes and secures the gate when
the gate is closed.
Lanyard Anchors
There are two lanyard anchors below the upper control
panel (refer to Figure 7.26).
Visually inspect the lanyard anchors to make sure they
are in place, are not deformed and are securely fastened
to the platform.
Operating Controls
Use the following procedure to operate the machine
from the upper controls.
1. Turn the battery disconnect switch on.
2. At the lower controls, pull the emergency stop but-
ton outward. Turn the switch to the upper control
position.
3. At the upper controls (refer to Figure 7.27), pull the
emergency stop button outward.
Figure 7.27 – Upper Controls
4. Turn the master 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.
A Danger
Pinch points may exist between moving compo-
nents. Death or serious injury can result from
becoming trapped between components, build-
ings, structures, or other obstacles. Make sure all
personnel stand clear of the aerial platform while
performing the prestart inspection.
A Warning
The potential for an accident increases when operat-
ing an aerial platform that is damaged or malfunc-
tioning. 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
function control without stepping on the foot switch.
If movement occurs the interlock is not function-
ing 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 a limit switch on the turn-
table that senses the main boom position. When
the main boom is raised slightly above horizontal
or extended approximately 2.4 m (8′) the machine
should travel in low speed only. To operate in high
speed the booms must be stowed.
