y
Hold the switch upward to raise the platform.
y
Hold the switch downward to lower the platform.
y
An alarm will sound as the platform lowers.
Upper Controls
The upper controls (refer to Figure 7.3) are located on the
control panel in the platform. The upper control pendant
is located at the right front of the platform. Platform and
drive functions can be operated from the upper controls.
Warning
The potential for an accident increases from improp-
erly driving or steering the aerial platform. Death or
serious injury could result from such accidents. Make
sure the upper control panel is securely fastened in-
side the platform and facing the front of the machine.
Avoid driving the platform with the upper controls facing
the rear or side of the machine. In this position the ma-
chine is difficult to control because the drive and steer
control movements and their resulting machine move-
ments will not correspond.
Only operate the upper controls when the upper control
panel is securely fastened inside the platform and facing
the front of the machine. Some machines may have an
optional removable upper control panel. Remove the pin
to remove the panel from the guardrails.
The following are located on the upper control panel:
y Emergency stop button
y
Drive/lift selector switch
y Drive range switch
y
Joystick to control platform lift, drive, and steer
y Horn button
y
Battery condition indicator
y Platform overload protection light
Emergency Stop Button
The emergency stop (refer to Figure 7.3) is a two-position,
red push button on the front of the upper control panel.
y Push the button inward to disconnect power from all
control circuits at the upper controls.
y
Pull the button outward to restore power. Some early
buttons require twisting to restore power.
y
Push the emergency stop button inward when the
upper controls are not in use to protect against
unintentional operation.
Note
On ANSI machines, the lower controls override the upper
controls. If the upper control emergency stop button is
engaged, the lower controls can still be used to operate
the aerial platform. On CE/AS/NZS machines, if one
emergency stop is engaged the machine will not operate.
Figure 7.3 – Upper Controls
