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.
