Guardrails
The guardrails (refer to Figure 4.6) help protect personnel
from falling off the platform.
The guardrail system includes:
A top rail
A mid rail
An entry gate
A wallboard loading gate
Toeboards around the sides of the platform.
Figure 4.6 – Upper Controls
The entry gate allows for access to the platform. The
gate must be securely latched except when personnel
are entering or leaving the platform.
The wallboard loading gate can be used for loading work
materials in the platform. The gate must be securely
fastened closed except when personnel are loading or
unloading work materials in the platform.
Lanyard Anchors
Four lanyard anchors for fall restraint anchorage are pro-
vided on the fl oor of the platform (refer to Figure 4.7):

Drive/Lift Level Sensor Interlock
The aerial platform drive and lift functions are interlocked
through a level sensor system. The drive/lift level sensor
interlock operates when the platform is elevated approxi-
mately 6′ (1.8 m).
If the chassis is tilted more than two degrees side-to-side
or front-to-rear, the drive and lift functions will not operate
and an alarm will sound.
Lower the platform and drive to a level surface when the
drive/lift level sensor alarm sounds.
The drive/lift level sensor system is for added protection
and does not justify operating on anything other than fi rm,
fl at, level surfaces.
Emergency Lowering Knob
The emergency lowering knob may be used to lower
the platform if there is a malfunction in the hydraulic or
electrical system. The knob is mounted at the rear of the
aerial platform (refer to Figure 4.4).
Figure 4.4 – Rear of Machine
Pull the emergency lowering knob outward to open the
cylinder bleed down valve for emergency lowering.
Safety Prop
The safety prop (refer to Figure 4.5) is used to support
the scissors structure when access to the scissors arm
components or the chassis is required. Always use the
safety prop when the platform is raised during inspection
and maintenance.
