SECTION 4 - MACHINE OPERATION
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 main or tower boom or swing the boom to the left or
right. Standard boom swing is 360 degree 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 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.
3121170– JLG Lift –4-1
SECTION 4 - MACHINE OPERATION
4.2HYDRAULIC SYSTEM WARM UP
The control system monitors the hydraulic system in extremely
cold temperatures and provides optimal performance by automatically limiting the function speeds of the high demand functions. The warm up mode automatically shuts off when system oil
reaches allowable temperatures.
While the system is cold and in the warm up mode, the tower lift,
main lift, and main telescope functions are limited to creep
speeds and is indicated to the operator by flashing the creep light
on the platform control panel.
Functions being operated when the warm up mode turns off will
remain in the creep speed until the function is re-initiated.
4.3BOOM OPERATING CHARACTERISTICS AND
LIMITATIONS
Capacities
The boom can be raised from the transport position with or without any load in platform, if:
1. Machine is positioned on a smooth, firm and level surface.
2. Axles are extended.
3. Load is within manufacturer’s rated capacity.
4. All machine systems are functioning properly.
5. Proper tire pressure.
6. Machine is as originally equipped from JLG.
4-2– JLG Lift –3121170
SECTION 4 - MACHINE OPERATION
Envelope Control System
The Envelope Control System is the primary means of controlling
the working positions of the tower and main boom within the
stability and structural requirements of the machine.
The main boom must be controlled in maximum angle and minimum angle to avoid entering a position that could compromise
backward stability and avoid main boom to tower boom interference. The tower boom must be controlled by permitting only
specific combinations of tower length and tower angle to avoid
entering a position that could compromise forward and backward stability (see Tower Path Control System).
Recognized failures within this system will result in control by the
Electrical Retrieval System (refer to the Service Manual), reduced
function speeds, and BCS warning light illumination. After
retrieval the boom will be restricted from leaving the transport
position until the failure is resolved.
Boom position violations outside of the allowable envelope will
result in reduced function speeds, BCS warning light illumination,
and restriction of functions. Attempts to operate restricted functions will cause the BCS warning light to flash and the platform
alarm to sound.
Violations of the tower path (with a healthy control system) will
cause the automatic combined operation of tower lift and tower
telescope to be suspended. A forward tower path violation can
be resolved by operating the tower lift up switch (tower tele-
scope out without auto tower lift up) or the tower lift down
switch (tower lift down without auto tower telescope in). A backward tower path violation can be resolved by operating the tower
lift up switch (tower lift up without auto tower telescope out) or
the tower lift down switch (tower telescope in without auto
tower lift down).
The restricted functions due to backward tower envelope violations are disallowing automatic tower lift down, automatic tower
telescope out, main lift up and down, main telescope in, jib,
swing, drive and steer.
The restricted functions due to forward tower envelope violations are disallowing automatic tower lift up, automatic tower
telescope in, main lift up and down, main telescope out, jib,
swing, drive and steer.
The restricted functions due to maximum main boom envelope
violations are disallowing tower lift up and down, main lift up,
main telescope in, jib, swing and drive.
The restricted functions due to minimum main boom envelope
violations are disallowing main lift down, swing and drive.

Tower Path Control System
The Tower Path Control System uses the envelope control sensors
to enhance the control of the tower boom for increased user efficiency and is used as an integral part of the envelope control system.
Both the ground and platform control panels use one function
switch to control the tower. User commands for tower lift up or
tower lift down causes the control system to automatically introduce the correct combination of tower telescope and tower lift
for the tower boom to follow a pre-described path or trajectory of
the tower nose.
4-4– JLG Lift –3121170
SECTION 4 - MACHINE OPERATION
Automatic Main Boom Control System
During combined tower lift and main lift functions, the control
system will maintain the tower lift speed and automatically vary
the maximum main lift command as needed to compensate for
the movement of the tower.
The interaction of the main boom and the tower boom is slightly
different when the main boom is above or below 60° relative to
gravity.
TOWER LIFT UP/DOWN - MAIN BOOM BELOW 60°
During tower lift up or down with the main boom below 60°, the
control system will maintain the angle of the main boom read at
the start of the tower lift command or as read at the conclusion of
main lift during combined tower and main lift commands.
TOWER LIFT DOWN - MAIN BOOM ABOVE 60°
During tower lift down with the main boom initially above 60°,
the control system will lower the main boom to approximately
60° before starting tower movement. The control system will then
control the main boom to 60° for the remainder of the tower lift
down command.
TOWER LIFT UP - MAIN BOOM ABOVE 60°
During tower lift up with the main boom already above 60°, the
control system will delay automatic compensation of the main
boom angle during tower lift until the main boom reaches
approximately 60°. The control system will then control the main
boom to 60° until the tower boom has reached its maximum
height. Continuing to operate the tower lift up when the tower
reaches its maximum height will cause the control system to
automatically raise the main boom to its original angle.
Slow Down System
The control system uses the envelope control sensors to automatically slow down the tower lift up and tower lift down at the
top of the tower path and to automatically slow down main lift
up and main lift down as the minimum and maximum angles of
the working envelope are approached. The control system indicates to the operator this slow down by flashing the creep light
on the platform display. This applies to both platform and ground
controls, however, no indication is made on the ground control
panel.
3121170– JLG Lift –4-5
SECTION 4 - MACHINE OPERATION
Controlled Angle
The Controlled Boom Angle System minimizes the interaction of
swing and drive functions with the envelope edges. This interaction is due to two factors. First, the envelope is controlled relative
to gravity regardless of ground slope and second, the turntable/
boom mounting is effected by swing and drive functions when
the ground slope varies. This can cause the boom position to vary
within the envelope or even violate the envelope edges when
swinging or driving without intentionally moving the boom. The
controlled boom angle system automatically activates either the
tower or main boom lift up or down during swing and drive commands to maintain a constant boom angle relative to gravity.
Controlled boom angle is disabled with any envelope violation or
failure.
Swing Speed Proportioning
The boom control system sensors sense the distance the platform
is extended from the centerline of rotation, allowing higher
swing speeds with the platform nearest to the centerline of rotation and gradually slower swing speeds the further the platform
gets from the centerline of rotation.
Stability
Machine stability is based on two (2) conditions which are called
FORWARD and BACKWARD stability. The machine’s position of
least FORWARD stability is shown in (See Figure 4-2.), and its position of least BACKWARD stability is shown in (See Figure 4-4.)
TO AVOID FORWARD OR BACKWARD TIPPING, DO NOT OVERLOAD MACHINE OR OPERATE THE MACHINE ON AN OUT-OF-LEVEL SURFACE.

SECTION 4 - MACHINE OPERATION
4.4AUXILIARY POWER OPERATION
The Auxiliary Power System provides a means of moving the platform in the event of an engine malfunction. This system uses an
electric motor/pump unit capable of operating all boom functions needed to allow the platform to be lowered to ground level.
With auxiliary power activated, the control system will attempt to
use the force of gravity to operate main lift down, tower lift down,
and tower telescope in. If appropriate movement is not detected
by the boom sensors, the auxiliary power system will supply
hydraulic flow to power boom movement. Allow sufficient operating time for system to respond.
NOTE:To ensure sufficient battery life, where possible, use the Main Lift
and Main Telescope functions to lower the platform to ground
level before using Tower Lift. Movements of the boom using auxiliary power will be SLOW and the movements will momentarily
stop and alternate between other functions as needed. When
operating Tower Lift, the movements will alternate between
tower lift, tower telescope, and main lift. When operating Main
Lift, the movements will alternate between main lift, tower lift,
and platform level.
4.5CAPACITY SELECT
The Boom Control System allows the operator to select operation
in a 500 lb. (227 kg for ANSI markets and 230 kg for CE and Australia markets) capacity restriction envelope or a 1000 lb. (454 kg for
ANSI markets and 450 kg for CE and Australia markets) capacity
restriction envelope. The operator selects the desired capacity
restriction by positioning the Capacity Select switch on the platform console. The Capacity Indicator shows the capacity selected,
and both capacity lights will flash and an alarm sound if the platform is out of the selected capacity range.
NOTE:Operation in the 1000 lb. (454 kg for ANSI markets and 450 kg for
CE and Australia markets) envelope requires the jib to be fixed in
the centered position.

4.7TRAVELING (DRIVING)
See Figure 4-6., Grade and Side Slopes
NOTE:Refer to the Operating Specifications table for Gradeability and
Sideslope ratings.
All ratings for Gradeability and Sideslope are based upon the
machine’s boom being in the stowed position, fully lowered, and
retracted.
DO NOT DRIVE WITH BOOM OUT OF TRANSPORT MODE EXCEPT ON A SMOOTH, FIRM
AND LEVEL SURFACE.
TO AVOID LOSS OF TRAVEL CONTROL OR “TIP OVER”, DO NOT DRIVE MACHINE ON
GRADES EXCEEDING THOSE SPECIFIED ON THE SERIAL NUMBER PLATE.
DO NOT DRIVE ON SIDESLOPES WHICH EXCEED 5 DEGREES.
USE EXTREME CAUTION WHEN DRIVING IN REVERSE AND AT ALL TIMES WHEN THE
PLATFORM IS ELEVATED.
BEFORE DRIVING, LOCATE THE BLACK/WHITE ORIENTATION ARROWS ON BOTH THE
CHASSIS AND THE PLATFORM CONTROLS. MOVE THE DRIVE CONTROLS IN A DIRECTION MATCHING THE DIRECTIONAL ARROWS.
SECTION 4 - MACHINE OPERATION
Traveling is limited by two factors:
1. Gradeability, which is the percent of grade of the incline the
machine can climb.
2. Sideslope, which is the angle of the slope the machine can
be driven across.
When the boom is raised or extended, the machine must not be
operated on grades or sideslopes that are greater than that
detected by the tilt alarm. The tilt alarm will sound to alert the
operator when the machine is on an unsafe slope. The machines
high drive function will also be cut back to low drive.

Traveling Forward and Reverse
1. At Platform Controls, pull out Emergency Stop switch, start
engine, and activate footswitch.
2. Position Drive controller to FORWARD or REVERSE as desired.
This machine is equipped with a Drive Orientation Indicator. The
yellow light on the platform control console indicates that the
boom is swung beyond the rear drive tires and the machine may
Drive/Steer in the opposite direction from the movement of the
controls. If the indicator is illuminated, operate the Drive function
in the following manner:
1. Match the black and white direction arrows on both platform control panel and the chassis to determine the direction the machine will travel.
2. Push and release the Drive Orientation Override switch.
Within 3 seconds, slowly move the Drive control toward the
arrow matching the intended direction of machine travel.
The indicator light will flash during the 3 second interval
until the drive function is selected.

A LEVEL SURFACE BEFORE RAISING BOOM.
TO AVOID SERIOUS INJURY, DO NOT OPERATE MACHINE IF ANY CONTROL LEVER OR
TOGGLE SWITCH CONTROLLING PLATFORM MOVEMENT DOES NOT RETURN TO THE
‘OFF’ OR NEUTRAL POSITION WHEN RELEASED.
IF THE PLATFORM DOES NOT STOP WHEN A CONTROL SWITCH OR LEVER IS RELEASED,
REMOVE FOOT FROM FOOTSWITCH OR USE EMERGENCY STOP SWITCH TO STOP THE
MACHINE.
Swinging the Boom
To swing boom, use Swing control to select Right or Left direction.
WHEN SWINGING THE BOOM MAKE SURE THERE IS AMPLE ROOM FOR THE BOOM TO
CLEAR SURROUNDING WALLS, PARTITIONS AND EQUIPMENT.

Hydraulic Oil
NOTE:Hydraulic oils must have anti-wear qualities at least to API Ser-
vice Classification GL-3, and sufficient chemical stability for
mobile hydraulic system service. JLG Industries recommends
Mobilfluid 424 hydraulic oil, which has an SAE viscosity index of
152.
NOTE:When temperatures remain consistently below 20 degrees F. (-7
3121170– JLG Lift –6-7
degrees C.), JLG Industries recommends the use of Mobil DTE13.
Aside from JLG recommendations, it is not advisable to mix oils of different brands or types, as they may not contain the same required additives or be of comparable viscosities. If use of hydraulic oil other than
Mobilfluid 424 is desired, contact JLG Industries for proper recommendations.
