Ground Operation Switch
The ground operation switch (refer to Figure 4.1) prevents
boom and platform movement if a control switch on the
lower control panel is accidentally moved.
Hold the switch up to operate the machine from the lower
controls.
Platform Foot Switch
Stepping down on the platform foot switch (refer to Figure
4.4) activates the upper controls.
Figure 4.4 – 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 guardrail system includes a top rail, mid rail, and
toeboards around the sides of the platform (refer to
Figure 4.4).
A gravity gate (refer to Figure 4.4) or an optional swing-
ing gate (refer to Figure 4.5) allows for access to the
platform.
Figure 4.5 – 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 platform
(refer to Figure 4.4).
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. Do not use the aerial platform for personal fall
arrest anchorage.
Tilt Alarm
If the aerial platform chassis is out of level more than 3.5
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 can 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.
Platform Overload Sensing System
All functions are stopped from the upper and lower
controls, when the platform overload limit is exceeded.
The horn will sound intermittently and the red overload
light (refer to Figure 4.6) will blink until the excess load
is removed from the platform. At that time, the machine
functions are again operational.
Note
If the platform overload sensing system is tripped while
operating the machine, the emergency power system
may still be used for emergency machine operation from
either the lower or upper controls.
