Platform Foot Switch
Step down on the platform foot switch (refer to Figure
4.3) to activate the upper controls.
Figure 4.3 – Platform
The foot switch must be engaged and a control must be
moved to operate the boom, drive, and/or platform from
the upper controls.
Guardrails
The guardrails (refer to Figure 4.3) help protect personnel
from falling off the platform.
The guardrail system includes:
• A top rail
• A mid rail
• Three gravity gates: one on each side and one rear
• Toeboards around the sides of the platform.
The gravity gates allow for access to the platform and
close automatically after entering or exiting the platform.
After entering the platform check to make sure the gates
are fully lowered and even with the mid rail.
Lanyard Anchors
Two lanyard anchors for fall restraint anchorage are pro-
vided below the upper controls at the front of the platform
(refer to Figure 4.3).
Note
The lanyard anchors are not for lifting or tying the ma-
chine down.
• All personnel in the platform must connect their fall
restraint device to a lanyard anchor before raising
the platform.
• Attach only one fall restraint device to each lanyard
anchor.
• Do not use the aerial platform for personal fall arrest
anchorage.
Ground Fault Circuit Interrupter
The electrical power outlet at the platform (refer to Figure
4.4) contains a ground fault circuit interrupter (GFCI) to
provide protection for personnel.

Tilt Alarm
If the aerial platform chassis is out of level more than five
degrees when the main boom is raised or extended, or
when the riser boom is raised, an alarm will sound. The
tilt alarm is located under the upper control panel.
A
Danger
The aerial platform can tip over if it becomes unstable.
Death or serious injury will result from a tip-over ac-
cident. 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 hazard.
Completely lower the booms 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
surfaces.
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.
High Engine Temperature Alarm
If the coolant exceeds the engine operating temperature
an alarm will sound and the engine will shut off.
Do not restart the engine until the condition that caused
the overheating has been corrected.
