3.4 CONTROLS AND INDICATORS
Precision Control Governor
This control allows the engine to remain at idle until any
function is activated, at which time the engine will acceler-
ate to perform that function. Upon release of the function
the engine will accelerate back to idle. High engine can
only be obtained if the drive handle is placed in the
extreme drive position, if the high engine switch is ON and
the boom is horizontal or below.
Ground Controls
DO NOT OPERATE FROM THE GROUND STATION WITH PERSON-
NEL IN THE PLATFORM EXCEPT IN AN EMERGENCY.
PERFORM PRE-OPERATIONAL CHECKS AND INSPECTIONS
FROM THE GROUND CONTROL STATION. WHEN PERSONNEL
ARE IN THE PLATFORM, OPERATION OF THE BOOM FROM THE
GROUND CONTROL WILL ONLY BE PERFORMED WITH THE PER-
MISSION OF THE PLATFORM OCCUPANT(S).
WHEN THE MACHINE IS SHUT DOWN THE MASTER/EMERGENCY
STOP SWITCH MUST BE POSITIONED TO THE “OFF” POSITION
TO PREVENT DRAINING THE BATTERY.
1. Master / Emergency Stop Switch.
A two-position key operated switch furnishes battery
power to the platform or ground control switches
when station power is selected from the ground con-
trol panel and the master switch is turned “ON”.
2. Control Station Selector.
A three position, center off, key activated PLAT-
FORM/GROUND SELECT switch supplies power to
the platform control console when positioned to
PLATFORM. With the switch in the GROUND posi-
tion, power is shut off to the platform station, and
only the controls on the ground control panel are
operable.
NOTE: With the Platform/Ground Select Switch in the center
position, power is shut off to controls at both operat-
ing stations.
TO AVOID SERIOUS INJURY, DO NOT OPERATE MACHINE IF ANY
CONTROL LEVERS OR TOGGLE SWITCHES CONTROLLING
PLATFORM MOVEMENT DO NOT RETURN TO THE OFF POSITION
WHEN RELEASED.
3. Ignition Switch.
The machine is equipped with an on-off ignition
switch and a separate start push button switch on
the ground control panel which supplies electrical
power to the starter solenoid when the ignition
switch is placed in the ON position and the START
button is depressed.
NOTE: One of the capacity indicator lights should be illumi-
nated at all times during operation. If no capacity
lights are on, a bulb could be burned out. Operation
of the machine must be halted until the lights are
working properly.
Check the capacity decal in the platform and at the
ground station for the machines operating capac-
ity(s).
4. Capacity Indicator.
The capacity indicator displays to the operator the
maximum rated platform capacity and the maximum
radius for that capacity using colored lights and a
reach diagram. The operator must not exceed the
rated capacity or the rated radius for the load (per-
sonnel, tools, and supplies) shown on the indicator.
A different color light for each different capacity is
used; blue indicates operating within maximum
capacity range, yellow indicates operating within
reduced capacity range. Models equipped with
Extend-A-Reach only have a blue and a red light.
When moving the platform from one capacity area to
another, one light will go out and another will come
on indicating the correct capacity for that area. A
steady red light indicates you have exceeded the
machines operating radius. You must immediately
stop all functions and then ’LIFT UP’’ or ‘’TELE IN’’
until the red light goes out. A blinking red light and a
buzzer sounding indicates you have exceeded the
platform load capacity (personnel, tools, and sup-
plies) and or radius. You must immediately stop and
then ‘’LIFT UP’’ or ‘’TELE IN’’ until the red light goes
out and the buzzer stops. Check to make sure the
load in the platform does not exceed the rated
capacity.
