SECTION 3 - MACHINE CONTROLS AND INDICATORS
Platform Control Indicator Panel
(See Figure 3-5., Platform Control Indicator Panel)
NOTE: The platform control indicator panel uses different shaped
symbols to alert the operator to different types of operational situations that could arise. The meaning of those
symbols are explained below.
Indicates a potentially hazardous situation, which
if not corrected, could result in serious injury or
death. This indicator will be red.
Indicates an abnormal operating condition,
which if not corrected, may result in machine
interruption or damage. This indicator will be yellow.
Indicates important information regarding the
operating condition, i.e. procedures essential for
safe operation. This indicator will be green with
the exception of the capacity indicator which will
be green or yellow depending upon platform
position.
1. Tilt Alarm Warning Light and Alarm
This illuminator indicates that the chassis is on a slope.
An alarm will also sound when the chassis is on a slope
and the boom is above horizontal. If lit when boom is
raised or extended, retract and lower to below horizontal
then reposition machine so that it is level before continuing operation. If the boom is above horizontal and the
machine is on a slope, the tilt alarm warning light will illuminate and an alarm will sound and CREEP is automatically activated.
IF TILT WARNING LIGHT IS ILLUMINATED WHEN BOOM IS RAISED OR
EXTENDED, RETRACT AND LOWER TO BELOW HORIZONTAL THEN
REPOSITION MACHINE SO THAT IT IS LEVEL BEFORE EXTENDING
BOOM OR RAISING BOOM ABOVE HORIZONTAL.

2. Platform Overload (If equipped)
Indicates the platform has been overloaded.
3. System Distress Indicator
The system distress indicator lights to signify an abnormal condition for the generator engine (high oil temperature or low oil pressure) or, on all electric machines, an
electrical system fault.
The four likely causes of a system fault are:
a. The seven second enable time has been allowed to
lapse or a function was selected before depressing
the footswitch. The system reads this condition as a
fault, just as it would if the footswitch were jammed
in the depressed position or a function switch were
stuck in the on position. Re-depress the footswitch
to power the controls and extinguish the light.
b. The maximum power limit has been reached and
the machine is not moving. This could happen
when the machine is stuck or when attempting to
travel over rough terrain or on steep grades which
exceed the rated gradeability of the machine. This
condition is comparable to stalling the engine by
asking it to provide more power than it was
designed to do.
c. The batteries are nearly depleted, and should be
charged very soon to prevent having the machine
stop at an inconvenient place.
d. There is some other fault in one of the circuits. If so
determine the cause by counting the flash code, a
number of flashes followed by a pause followed by
another number of flashes, and refer to the service
manual.
NOTE: The engine will automatically shut down under the follow-
ing conditions:
High Engine Oil Temperature
Low Engine Oil Pressure
Engine Overspeed
Generator Overvoltage
4. Posi-Track Indicator
This indicator lights to show that posi-traction is operating.
3-14– JLG Lift –3121210
Page 45
SECTION 3 - MACHINE CONTROLS AND INDICATORS
5. Enable Indicator/Footswitch
To operate any function, the footswitch must be
depressed and the function selected within seven seconds. The enable indicator shows that the controls are
enabled. If a function is not selected within seven seconds, or if a seven second lapse between ending one
function and beginning the next function, the enable
light will go out and the footswitch must be released and
depressed again to enable the controls.
Releasing the footswitch removes power from all controls and applies the drive brakes.
TO AVOID SERIOUS INJURY, DO NOT REMOVE, MODIFY OR DISABLE
THE FOOTSWITCH BY BLOCKING OR ANY OTHER MEANS.
FOOTSWITCH MUST BE ADJUSTED IF FUNCTIONS ACTIVATE WHEN
SWITCH ONLY OPERATES WITHIN LAST 1/4" OF TRAVEL, TOP OR BOTTOM.
6. Low Battery Indicator
Indicates the batteries are low and need to be charged.

Page 46
SECTION 3 - MACHINE CONTROLS AND INDICATORS
7. Creep Speed Indicator
When the Function Speed Control is turned to the creep
position, the indicator acts as a reminder that all functions are set to the slowest speed.
8. Drive Orientation Indicator
When the boom is swung beyond the rear drive tires or
further in either direction, the Drive Orientation indicator
will illuminate when the drive function is selected. This is
a signal for the operator to activate the Drive Orientation
Override Switch and verify the drive control direction is
correct.
9. Soft Touch Indicator (If Equipped)
When illuminated (Yellow) the Soft Touch bumper is
against an object. All controls are disabled until the
override button is pushed, at which time controls are
active in the Creep mode.

4.1DESCRIPTION
This machine is a self-propelled hydraulic personnel lift
equipped with a work platform on the end of an elevating
and rotating boom.
The primary operator control station is in the platform. From
this control station, the operator can drive and steer the
machine in both forward and reverse directions. The operator can raise or lower the upper or lower boom or swing the
boom to the left or right. Standard boom swing is 360 degree
non-continuous left and right of the stowed position. The
machine has a Ground Control Station which will override
the Platform Control Station. Ground Controls operate Upper
and Lower Boom Lift and Swing, and are to be used in an
emergency to lower the platform to the ground should the
operator in the platform be unable to do so.
4.2OPERATING CHARACTERISTICS AND
LIMITATIONS
Capacities
The boom can be raised above horizontal with or without any
load in platform, if:
1. Machine is positioned on a smooth, firm and level surface.
2. Load is within manufacturers rated design capacity.
