Ground Controls Switch
The ground controls switch (refer to Figure 4.1) pre-
vents boom and platform movement if a control switch
on the lower control panel is accidentally moved.
Hold the switch in the controls on position to operate the
machine from the lower controls.
Platform Foot Switch
The platform foot switch (refer to Figure 4.4) prevents
boom and platform movement if a control on the upper
control panel is accidentally moved.
Figure 4.4—Platform
Step down on the platform foot switch to activate the
boom and platform controls.
Guardrails
The guardrail system includes a top rail, mid rail, and
toeboards around the sides of the platform (refer to Fig-
ure 4.4).
A gravity gate or an optional swinging gate allows for ac-
cess to the platform. The gates close automatically after
entering or exiting the platform. The gate is part of the
guardrail system and must be securely fastened after
entering the platform.
Lanyard Anchors
Two lanyard anchors for fall restraint anchorage are pro-
vided below the upper controls at the front of the plat-
form (refer to Figure 4.4).
Note
The lanyard anchors are not for lifting or tying the
machine down.
All personnel in the platform must connect their fall re-
straint device to a lanyard anchor before raising the plat-
form. Do not use the aerial platform for personal fall
arrest anchorage.
Ground Fault Circuit Interrupter
The electrical power outlet (refer to Figure 4.5), at the
platform contains a ground fault circuit interrupter
(GFCI) to help prevent accidental conductor grounding.

Tilt Alarm
If the aerial platform chassis is out of level more than
five degrees when the main boom is raised or extended,
an alarm will sound.
The aerial platform can tip over if it becomes unsta-
ble. Death or serious injury can result from a
tip-over accident. Do not drive or position the aerial
platform for elevated use near any drop-off, hole,
slope, soft or uneven ground, or other tip-over haz-
ard.
Completely lower and retract the main boom and then
drive to a level surface when the tilt alarm sounds.
The tilt alarm is for added protection and does not justify
operating on anything other than firm, flat, level sur-
faces.
Engine Protection Systems
A constant tone alarm will sound to warn against high
engine temperature or low oil pressure.
The engine will shut-down if the operating temperature
exceeds a preset level or if the oil pressure is too low for
safe operation. An engine temperature gauge is below
the lower control panel (refer to Figure 4.6).
