The emergency stop is a two-position, red push button
on the top of the upper control panel. Push the button in
to disconnect power to all control circuits at the upper
controls. Pull the button out to restore power.
Note
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 plat-
form.
Push the emergency stop button in when the upper con-
trols are not in use to protect against unintentional op-
eration.
Start Switch
The engine can be started from the platform using the
anti-restart master switch on the front of the upper con-
trol panel (refer to Figure 6.6).

This switch is similar to an automobile ignition switch.
Turn the switch to start until the engine starts, then re-
lease 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.
