(15) Alarm horn
Before moving the machine, sound the alarm
horn to warn the personnel around the machine.
(16) Overload Sensing System
This system disables all of the functions, the
overload warning light flashes and the alarm
buzzer sounds when the platform is overloaded.
(17) Boom / Travel Function Interlock System
This system does not allow the boom/
platform functions and the travel functions
simultaneously, unless the boom is retracted
fully and set below 5 degrees. (Area C of the
travel speed limit system: See Section 2.)
It allows the boom/platform functions or
the travel functions which is operated first,
and cancels the other functions, when these
functions are operated simultaneously.
(18) Boom Wire Rope Failure Detecting System
This system disables the boom extending
functions in the event of the boom extension
wire rope failure.
(19) Foot Switch, Enable Switch
To help prevent a misoperation, the boom,
platform, and traveling functions are disabled
unless the foot switch is depressed or the
enable switch is operated.
(20) Foot Switch Cancel System
This system cancels the foot switch/enable
switch if any of the boom platform, and
traveling function is not operatedfor more than
20 seconds after operating the foot switch/
enable switch.
The system also cancels the functions if the
foot switch/enable switch is not operated for
more than 20 seconds after operating any of
the boom, platform, and traveling function.
At this time, the power indicator light (on the
upper controls) or the preheat light (on the
lower controls) starts flashing to alert you.
In this case, release all controls and the power
indicator light will turn on or the preheat light
will turn off. And then operate again to enable
the functions.
2. Travel Speed Limit System
This system automatically limits the travel speed
according to the boom status as follows.
