Chapter 8 – Prestart Inspection
24 S1930 – 0361518EE
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 guard-
rails in place must be present and not show any signs of
looseness.
Inspect the gravity gate to be sure it is present and se-
curely fastened to the rail. The chain must be free of
damage and deformation that may prevent if from func-
tioning properly. Inspect the pin that secures the gate.
Inspect the wallboard loading gate to see that it swings
freely, closes firmly, and is not deformed in any way. Make
sure the gate is secure when it is closed.
Platform Extension
A pin at the left front of the platform secures the exten-
sion deck and the upper controls to the main platform
deck. Inspect the pin (refer to Figure 8.18) to ensure that
it properly secures the extension deck. Release the pin
to extend the platform. Extend the platform while check-
ing for proper operation.
Figure 8.18 – Platform Extension Pin
Extend the platform and inspect the weldments for defor-
mation and damage. Visually check the platform welds
for cracks. Retract the deck and install the pin to secure
it to the platform.
Swing-Down Rails
Inspect the pins that hold the rails in position (refer to
Figure 8.19) to make sure they are all in place and are
not deformed. There is one pin on the top rail, one on the
gravity gate and one on each of the vertical platform tubes.
There are also two pins on the front panel and two that
fasten the upper controls to the platform rails. One of the
pins that holds the upper controls in place is the platform
extension pin.
Raise the platform from the lower controls to visually in-
spect the slide blocks underneath the front of the plat-
form (refer to Figure 8.16).
Figure 8.16 – Platform Slide Blocks
There is one slide block on each side of the platform. The
slide blocks must be in good condition and free to move
without obstruction.
Fasteners
Visually inspect all fasteners to see that none are miss-
ing or loose.
Pay particular attention to all of the bolts, nuts, roll pins,
collars, and snap rings that connect the scissors arms.
They should all be present, tight, and not damaged in
any way.
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 8.17) includes the
top rail, mid rail, toeboards and an gravity gate.
