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 7.18) includes the
top rail, mid rail, toeboards and a gravity gate or op-
tional swinging gate.
Figure 7.18 – Guardrail System
Inspect all components of the guardrail system. The rails
and toeboards must all be in place and free of any dam-
age or deformation. Visually check the rail and toeboard
welds for cracks. All bolts and nuts fastening the plat-
form 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 7.18).
Visually inspect the lanyard anchors to make sure they
are in place, are not deformed and are securely fas-
tened 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. Insert the key in the control selector
and turn the switch to the upper control position.
3. At the upper controls (refer to Figure 7.19), pull the
emergency stop button outward.
Figure 7.16 – Boom Sections
Inspect the surface where the pads contact the inter-
mediate and tip booms. The paint must be in place with
no signs of bare metal.
Fasteners
Visually inspect all fasteners to see that none are miss-
ing or loose.
Pay particular attention to all of the bolts, nuts, rollpins,
collars, and snap rings that connect the booms and cyl-
inders. They should all be present, tight, and not dam-
aged in any way.
Raise the main boom to access the rotation bearing bolts
in the turntable (refer to Figure 7.17).
Inspect the rotation bearing bolts to ensure that none
are missing, damaged, or loose.
