Guardrail System
The guardrail system (refer to Figure 6.17)
includes the top rail, mid rail, toeboards and a
gravity gate or optional swinging gate.
Figure 6.17—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 guardrails 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 latch 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 6.17).
Visually inspect the lanyard anchors to make sure
they are in place, are not deformed and are
securely fastened to the platform.
❑ Operating Controls
Place the battery disconnect switch in the on
position and pull the emergency stop button out on
the lower control panel.
From the upper controls, test the platform foot
switch by selecting a boom function and moving
the boom joystick without stepping on the foot
switch. If movement occurs the interlock is not
functioning properly. Do not operate the machine
until the problem is corrected.
Test the operation of each control in both directions
from the upper controls (refer to Figure 6.18).
Note
The SP20 does not have a jib boom.
