Note
On some machines it may be necessary to pause about
three seconds in the on position before going to start so
the starter can engage.
If the platform is to stay in a particular position for a long
time, turn the start switch to off to shut off the engine and
save fuel.
Emergency Stop Button
The emergency stop is a two-position, red push button on
the top of the upper control panel (refer to Figure 6.6).
• Push the button inward to disconnect power from all
control circuits at the upper controls.
• Pull the button outward to restore power.
Note
The lower controls override the upper controls. If the up-
per control emergency stop button is engaged the lower
controls can still be used to operate the aerial platform.
• Push the emergency stop button inward when the
upper controls are not in use to protect against un-
intentional operation.
Drive Joystick
The drive joystick (refer to Figure 6.6) is used to control
forward and reverse motion of the aerial platform. The
distance the joystick is moved is proportional to the ma-
chine drive speed.
Figure 6.7 – Upper Control Panel Front
Start Switch
The engine can be started from the platform using the
start switch on the front of the upper control panel (refer
to Figure 6.7).
This switch is similar to an automobile ignition switch.
• Turn the switch to start until the engine starts, then
release it to on.
• If the engine dies, the switch must be turned to off
before it can be turned back to start.
An alarm sounds, when the switch is turned on, to warn
others that the machine engine is being started.
