2. TECHNICAL INFORMATION
2.1. DESCRIPTION OF THE MACHINE
The machine is a self‑propelled hydraulic lifting device, fitted with a rotating basket positio‑
ned at the top of an extendable articulated structure, which also rotates. The lifting device is
intended for POSITIONING PERSONS AND THEIR EQUIPMENT AND MATERIALS AT A
HEIGHT ABOVE GROUND LEVEL.
2.1.1 CONTROL POSITION
The elevating platform was designed so that its carriage can be controlled by means of a
radio control that communicates with a receiver device located inside the distributor support
in the basket. All the controls for the movements of the carriage are grouped on the radio
control, and the radio control display shows all the information regarding the use of the
machine (both aerial part and carriage) and the diagnostic functions.
The aerial part of the machine is controlled by means of hydraulic levers located in the
basket and in the emergency control position on board the machine.
The control positions are defined according to the operations to be carried out as listed
below.
The aerial part control position is located inside the basket, at the level of the aerial part
hydraulic distributor. To ensure that this control position can be used, all the movements of
the aerial part must be enabled and the radio control must be positioned in its seat in the
basket; if the radio control is positioned incorrectly, the yellow warning light on the left side
of the distributor comes on.

1 Basket levelling control
This lever allows the basket levelling
cylinder to be operated in order to
compensate for possible misalignments
due to system failures.
Since this is an emergency device and
the manoeuvre is dangerous, the ope‑
rator must use a tool to activate the
distributor.
It is advisable to carry out this operation
with the aerial part completely closed.

AERIAL PART EMERGENCY
There is a second control position for the aerial part which is called aerial part emergency
control position. This position is on the ground, on the side of the machine, near the aerial
part hydraulic distributor on the ground. In order to enable this control position it is neces‑
sary to use the switch located on the left side of the distributor. This control position must be
used only for emergency manoeuvres or when servicing the machine.

The emergency control position was designed to operate on the extensible structure only
for emergency operations by emergency service personnel on the ground, who must in
any case be trained and know the operation of the machine and its safety devices, as well
as for maintenance and checks before starting work.
If an operator is in the basket, it is forbidden to move the structure from the ground posi
‑
tion, unless in an emergency situation (sudden operator illness, technical fault).
TRAVEL
The travel control position is not defined univocally but it is located within the area around
the machine, at a distance of minimum 1 m from the latter, and up to the limit distance
allowed by the radio signal (this data varies according to the conditions in the environment
where the machine is used).
When controlling the machine from the ground position, always make sure that the com‑
ponent that is being moved is completely visible and constantly check its trajectory.
It is absolutely forbidden to use the radio control to move the machine when this cannot
be seen by the operator.
The machine can travel only if there are no persons, animals or things in the basket.
When controlling the machine from the ground by means of the radio control, keep a
distance of at least 1 m from the tracks.

2.2 GENERAL SAFETY STANDARDS
The functioning of the MEWP must be in compliance with international standards of refe‑
rence (see paragraph “NORMATIVE REFERENCES” in the first pages of the manual) and
national or regional standards if stricter.
The operator must read, understand and follow all the instructions and warnings, contained
in this manual and on the machine, regarding the safe use of the MEWP.
FAILURE TO COMPLY WITH THE SAFETY PRECAUTIONS LISTED IN THIS SECTION
AND PROVIDED ON THE MACHINE CAN DAMAGE THE MACHINE AND CAUSE
INJURY OR EVEN DEATH, AND CONSTITUTES A SERIOUS BREACH OF THE SAFETY
RULES.
This section of the USER AND OPERATION MANUAL describes those procedures or dan‑
gerous situations that can cause damage/injury to objects/persons and explains what the
operator must do to prevent them.
‑ Operators must always act professionally, complying with safety standards, making sure
not to underestimate their responsibility to themselves and the surrounding objects and per‑
sons.
‑ Before starting work, operators must receive complete and clear training regarding the
use of the machine in standard and emergency conditions. They must examine, under‑
stand and take in all the instructions given in this user manual. They must be sure that
the safety devices are in perfect working order, perform the necessary checks on the
machine and be familiar with the conditions of the ground on which the machine is going
to be operated and stabilised.
‑ The presence of at least one specialist operator is necessary on the ground during work.
This person must know how to use the machine, be aware of the contents of the USER AND
OPERATION MANUAL and be able to intervene if necessary.
‑ It is prohibited to make modifications to the machine that could affect operation and safety,
without the previous written authorisation of the Constructor. The latter is not liable for any
injury or damage caused by such actions.
Clothing and protective equipment
Avoid wearing loose clothing, rings, watches or anything else
that may get caught in moving parts.
When using the machine or performing maintenance, wear a
hard hat, glasses, safety footwear, gloves and acoustic ear‑
muffs after making sure these and all other PPE that the
safety manager considers necessary based on the risk analy‑

GE POINTS ON THE BASKET. THE USE OF HARNESSES IS COMPULSORY IN ACCORDANCE WITH LOCAL
LEGISLATION IN EACH INDIVIDUAL COUNTRY
. IN CONTRIES WHERE THE LAW DOES NOT REQUIRE THE
USE OF SUCH SAFETY SYSTEMS
, THE EMPLOYER AND/OR USER IS RESPONSIBLE FOR CHOOSING THE
SYSTEM TO BE USED
.
Safety valves and electrical system safety components
It is prohibited to modify and/or tamper with the safety and control valves on the main
hydraulic system and the settings of the electrical system.
The Constructor is not liable for injury to persons and damage to objects or the machine if
the standard setting of any hydraulic and electrical/electronic component is tampered
with.
Fire prevention
Keep the area around the motor clean, removing fragments of
wood, paper and other flammable products; clean any fuel
leaks as these may be a potential cause of fire.
Petrol is extremely flammable and explosive in particular con‑
ditions. Refuel in well ventilated areas and with the engine at
rest.
Avoid smoking and producing sparks in the refuelling and fuel storage area.
After refuelling, make sure to put back the cap correctly. Take care to avoid touching the
exhaust silencer when this is hot, i.e. with the machine running or soon after stopping the
engine.
Preventing damage caused by washing the machine
Do not direct high pressure jets towards the electrical compo‑
nents while washing the machine. Do not use chemical deter‑
gents or petrol that would damage the plastic parts and the
painting

• Cleaning the machine
Always park the machine as shown in the figure in point 2.1.4.
When washing the machine, the ignition block must be disengaged, the key removed and the
emergency stop button pressed.
• Washing the outside of the machine
Never use flammable liquids. Adopt the above safety measures to
prevent sparks due to short‑circuits.
If washing the track with water cleaners, carefully protect all the
important parts and above all the electrical components. Follow the
instructions provided by the manufacturer of the detergent.
Clean the machine using water‑soluble detergents.
The more the elevating platform is cleaned, the more it will need to be greased (see par. 3.3
Grease points).
Do not wet the electric motors and the other electrical components directly. Do not aim the
spray directly onto adhesive labels and rating plates.
• Cleaning the electrical system
Never clean the inverter or the electric motor with water, as this may
cause damage to the electrical system.

Only use dry detergents, in accordance with the manufacturer’s instructions. Never remove
covers, guards and the like.
‑ Clean the electrical system using a dry, non‑metallic brush and low pressure air.
• After cleaning
Dry the machine carefully before starting it again (for example using compressed air).
If, despite all the precautions, moisture has penetrated into the electric motor or other parts
of the electric system, these must be dried using compressed air to avoid the risk of short‑cir‑
cuits.
Preventing damage that may be caused by the machine during work
When the machine has been stabilised and work has started, never enter its operating area.
Always operate the controls slowly and smoothly and avoid reversing the movements sud‑
denly.
When operating outside of the basket, ALWAYS keep a MINIMUM distance of 1 METRE
from the machine.

2.3 SAFETY WARNINGS
2.3.1 GENERALITIES
To avoid accidents, before starting work and before performing
any maintenance operations, it is necessary to read, understand
and follow all the precautions and warnings contained in this
manual.
The user/operator of the machine must decline all responsibility
for operation until having read this manual and fully under‑
stood how to use the machine under the supervision of an

3 SAFETY DEVICES
The information given below concerning the safety devices are provided to the user in order
to allow him/her to understand the machine behaviour and possible work sequences; moreo‑
ver, in this way it is possible to identify any breakdowns with greater precision and to sup‑
ply more detailed information to the after‑sales service for quicker, less expensive interven‑
tions.
The machine is fitted with safety devices used to prevent dangerous situations for the opera‑
tor. It is important that before starting any operation the operator checks the perfect working
order of these devices.
The malfunctioning of a safety device, whether caused by a fault or tampering, can cause
serious damage to the machine and consequently put the operator’s life at risk. The Con‑
structor designed the machine and the safety devices so as to guarantee the maximum safety
to its customers, however the devices must be checked periodically as described in this
manual and they must never be tampered with.
The service function on the radio control can be used as an aid in checking electrical safety
devices.
Never intervene on the safety devices. If they are tampered with the manufacturer declines
all liability regarding any accidents that may be due to such tampering.
It is prohibited to tamper with the lead sealing or setting of the maximum pressure valves
and the adjustments of the electrical components. If they are tampered with, the manufactu‑
rer declines all liability regarding any accidents that may be due to such tampering.
The Constructor is not liable for any damage/injury caused by the machine due to failure to
comply with the above instructions.

3.1 BATTERY CUTOUT SWITCH
This device, located on the left side of the electrical components compartment, is used to iso‑
late the machine’s electrical circuit, stopping any movements.
It is well‑visible and easily accessed without using tools. It only needs to be activated for pro‑
longed machine downtime or maintenance operations.
Turning the key clockwise closes the machine’s electrical circuit, while turning it anticlockwi‑
se isolates the machine’s electrical circuit and the key can be removed.
B
EFORE DISCONNECTING THE BATTERY BY MEANS OF THIS DEVICE, MAKE SURE THAT THE ENGINE
KEY IS IN POSITION
“OFF”, THE RADIO CONTROL EMERGENCY STOP BUTTON HAS BEEN PRESSED AND
THE RADIO CONTROL AND ELECTRONIC BOARD ARE OFF
.
3.2 D
ISTRIBUTOR PRESSURE RELIEF VALVES
All platform distributors have a pressure relief valve that limits the pressure inside the
system to the value set for the same valve.
These valves are set when the platform is tested by qualified personnel and must not be tam‑
pered with for any reason whatsoever.
IMPORTANT
THERMIC MOTOR
LITHIUM MOTOR
IMPORTANTE
3.3 CYLINDER STOP VALVES
The stabiliser cylinders have a double stop valve which in case of system breakdown or hose
breakage stops the cylinder preventing dangerous platform instability situations.
All cylinders that move the aerial part of the platform structure are fitted with a stop valve
which in case of system breakdown or hose breakage stops the cylinder preventing the
basket from falling due to gravity.
These valves are set when the platform is tested by qualified personnel and must not be
tampered with for any reason whatsoever.
3.4 A
LIGNMENT PHOTOCELLS ON THE AERIAL PART OF THE STRUCTURE AND THE BASE OF THE
MACHINE
The platform has two safety photocells that ensure that the aerial part of the machine is com‑
pletely lowered and aligned with the base and that the telescopic arm is completely retrac‑
ted.
When these conditions are not met, a signal is sent that disables the movement of the stabili‑
sers.
X17JR0420113
42
BOOM LIFT MODELS X17J
JLG
3.5 STABILISER POSITION MICROSWITCHES
The position of the stabilisers and their contact with the ground are detected by 4 microswit‑
ches positioned near the stabiliser cylinder rod fastening pin.
The microswitches fixed to the stabiliser must be released when the stabiliser rests on the
ground.
Check the correct operation of the microswitches every day.
3.6 J
IB POSITION MICROSWITCH
The position of the jib arm is detected by a microswitch
that is secured to the jib arm itself and works in a slot
made in the jib transmission.
The microswitch must be released when the jib arm is clo‑
sed.
Check the condition and correct operation of the JIB microswitch every day.
3.7 B
ASKET LOAD SENSOR
The load sensor on the basket is made up of a basket sup‑
port with two shafts that only allow the vertical move‑
ment of the basket. The basket support is supplied by the
load cell itself. Two strain gauges are positioned inside
the sensor positioned under the basket and convert the
relative weight inside the basket into an electrical signal.
The electrical signal is then sent to the electronic board,
which processes it and identifies any dangerous condi‑
tions.
X17JR0420113
BOOM LIFT MODELS X17J
JLG
43
The max load depends on the working mode. If the machine works with the jib open, the
load is 120 kg. In case of operation with the jib closed, the maximum load allowed is 200 kg.
The radio control display always shows the maximum load allowed according to the work
mode.
When the maximum allowable load is reached, an icon appears on the radio control display,
a sound signal is emitted and all platform movements are disabled. To restore platform ope‑
ration the excess weight must be removed in order to return below the maximum allowable
weight (see paragraph on the display).
The Constructor recommends that maximum attention is paid
to the conditions of all safety components and in particular of
the system that makes up the basket load sensor; always check
correct operation whenever objects are struck with the basket or
if performing operations that may damage the system (e.g. pru‑
ning, painting etc.).
Before any elevating manoeuvre, always make sure that the two closing covers on the ver‑
tical pins are completely screwed in.
3.8 C
ONTROL PROTECTION
A protection structure is provided to protect the radio control against the accidental fall of
objects from above and involuntary activation by the operator.
Always make sure that this protection structure is intact before using the machine.
Special protection structures and plate casings are provided to protect the control levers of
all distributors against the accidental fall of objects from above and involuntary activation by
the operator.

PIRIT LEVEL
The spirit level is positioned on the turret and it is readily visible
from the basket and from the ground. The spirit level must be
used to make sure that during the platform levelling phase the
maximum allowable gradient of 1° is complied with. This condi‑
tion is met when the air bubble is inside the green area.
A second electronic spirit level contained in the control board makes sure that this condition
is effectively satisfied and checks the power supply to the controls for the aerial part.
Always check the correct levelling of the machine after every self‑levelling operation.
Approximate levelling outside of the limits set by the manufacturer is very dangerous and
can affect the stability of the platform, which represents a risk, even deadly, for the operator
and other persons working on the machine and near it.
Never tamper with the spirit level; this device is set by the Constructor during testing before
sale. Only technicians authorised by JLG using suitable tools may adjust the spirit level.
3.10 P
IN LOCKING BOLTS AND NUTS
All the pins used on the platform were treated against wear and are fitted with welded flan‑
ges (1) to prevent them from rotating inside their seat. Some pins have bolts to stop rotation
(2) while others pins have a joint in the structure of the machine (3).

The pins in the most delicate positions are threaded at the ends and are fitted with self‑
locking nuts (4) or self‑locking threaded ring nuts to prevent the structure from subsiding.
Check the correct tightness of all the pin locking devices according to the intervals indicated
by the manufacturer of the machine.
Never loosen the pin locking devices and periodically check they are correctly tightened. A
pin that comes off its housing, even partially, may cause unexpected and uncontrollable
movements and even cause the machine to lose stability and/or the basket to fall.
3.11 S
AFETY DEVICE ELECTRONIC CONTROL BOARD
The platform has an electronic control board (see photo)
that enables the power supply to the ON‑OFF proportional
coils after verification of the safety conditions by the sen‑
sors positioned on the machine.
The control procedure on the electronic board may be
bypassed using the key selector switch with spring return:
“safety device bypass key”.
The electronic board records every bypass action carried
out by the operator on the safety devices, filing them by
date, time and lapse of time during which the operator held
the “safety device bypass key” in position.
The board is also provided with an event record that stores all the operations performed on
the machine for a variable period of time.

4 INSTRUMENTS AND CONTROLS
Below is a description of all the controls and indicators present on the platform; each device
has a sticker that briefly describes its function applied nearby, often containing symbols that
are used to ensure quick and clear understanding. Before using the platform, the following
descriptions must be read in order to gain in‑depth knowledge of the functions of each devi‑
ce and to be aware of any suggestions provided by the manufacturer.
Before starting to use the platform, the operator must read and perfectly understand all the
instructions contained in this manual.
4.1 RADIO CONTROL
The radio control contains most of the controls required for normal operation of the machi‑
ne’s carriage.
The radio control comprises push buttons, joysticks and the display.
The radio control continuously exchanges data with the machine’s main board, which in turn
transmits the information to be shown on the display.

4.1.1 DISPLAY
The display is used to view the status of the machine and the operating information neces‑
sary or useful for the operator.
When the machine and the radio control are switched on, the main control board of the
machine sends the radio control the information to be displayed.
This operation has a variable duration. Normally a few seconds are sufficient, however the
following download screen may appear on the display:
The display shows the information
transmission status through the
increasing number on the bottom
left side.
In this case about 20 minutes are needed to send all the information from the main board to
the radio control.
The machine cannot work during this period.
Do not stop the machine or operate it during this period.
4.1.1.1 D
ISPLAY MAIN SCREEN

inactive (see photo). If the electronic board of the machine is on and the radio control is not
too far from the machine, the latter will synchronize to the receiver and will be ready for use
in about 10 seconds, while the display will show the main screen.
If the electronic board of the machine is off or the radio control
is too far from the machine, the latter will not complete the syn‑
chronization procedure and the signal search status will keep
appearing on the display.
To verify if the electronic board is on, make sure that the leds of
the receiver are on.
Once the machine and the radio control have been started, the main screen giving a general
overview of the machine status will appear. For the sake of simplicity and clarity a layout is
provided with 8 icon display positions.

5 EMERGENCY DEVICES
The following information concerning the emergency devices is provided to help understand
the behaviour of the machine and the possible work sequences; moreover, the devices can
thus be identified more clearly and quicker action can be taken if emergencies occur.
It is important that before starting any operation the operator checks the perfect
working order of the emergency devices.
5.1 E
MERGENCY STOP BUTTON
Allows immediate shutdown of all machine functions in emergency conditions.
The machine is provided with three emergency stop devices: the first is located on the carria‑
ge just above the turntable, the second on the radio control and the third is connected to the
basket. Once the device has been activated, the button must be turned and released to allow
the machine to operate again.
Selection of the emergency stop is indicated on the radio control display.
It is strongly recommended to comply with the rule whereby the platform must not be ope‑
rated without personnel available on the ground. Indeed, accidental operation (e.g. due to a
falling branch) or voluntary operation of the emergency button by unauthorised persons on
the ground would put the occupants of the basket in the unpleasant situation of not being
able to perform any movements, except descent using the emergency descent devices.

5.2 HAND PUMP
The hand pump (2) is used to pressurise oil for emergency movements made necessary by
any breakdown of the main hydraulic system.
The hand pump has a manual diverter (1) used to select whether to control the two right sta‑
bilisers (Position A) or to control the two left stabilisers and the aerial part of the structure
(Position B).
See paragraph “Emergency manoeuvres”.
5.3 S
OLENOID VALVES FOR EMERGENCY DESCENT
The cylinders of the first‑second arm, of the third arm and the jib
have a solenoid valve for emergency descent (1). Activating the
emergency descent button on the remote control energises these
solenoid valves, which allow the descent of the aerial part of the
structure due to gravity.
The use of this emergency device depends on the platform’s elec‑
trical system being powered.
5.4 S
AFETY DEVICE BYPASS KEY
The machine has a key device that acts on the electrical circuit, bypassing the platform safety
systems. The device is situated on the cover of the electrical components compartment.
The use of this selector switch is illustrated in the following paragraphs on how to use the
machine.
Considering the hazard deriving from the use of the platform during the bypass of the
safety devices, carefully read the paragraphs regarding the use of the safety device release
key selector switch.

PERICOLO
DANGER
The key used to activate the safety device bypass is lead‑sealed on the side of the electri‑
cal components compartment near the battery.
Force the lead‑sealing to remove it. After using the safety device bypass a JLG after‑sales
centre must be contacted in order to verify the causes that determined the necessity to use
the safety device bypass and to lead‑seal the key.
The safety device electronic control board records every time the safety device bypass key
is activated along with the movements made during these operations.
The safety device bypass system is used to move the machine with a higher load than the
limit load allowed inside the basket; the overload alarm is nonetheless displayed and the
beeper warns the operator of the dangerous conditions. This device must only be used by
expert personnel trained on how to use the machine, while the end user, who does not
fully know the machine’s operating principles, is not allowed to use this device.

5.6 SWITCH TO ENABLE EMERGENCY CONTROLS
This device (1) is a valve and allows the operator on the ground to switch the controls from
the position on the basket to the emergency position on the revolving turret (2).
Turn deviator, turn clockwise the key and keep it in position, then move levers and the struc‑
ture will move.
It is strongly recommended to comply with the rule whereby the platform must not be ope‑
rated without personnel available on the ground. In fact, operation of the switch by non
authorized personnel would place the operator in the basket in the unpleasant condition of
not being able to carry out any movement and of being subjected to the movements control‑
led from the ground. If this should occur, press the emergency button and call for help, or
use the emergency descent devices.
‑ AERIAL PART HYDRAULIC DISTRIBUTOR
The hydraulic distributor is fitted with levers for the selection of the required movement, its
direction and speed. The structure can be moved by using the levers after operating the swit‑
ch.
For more information on the function of the levers located on the distributor, see paragraph
“Control position”.

6.1.3 DANGER DUE TO THE WORK AREA
THE MACHINE CAN ONLY WORK ON COMPACT AND LEVEL GROUND.
Always verify that the slope of the ground in the platform positioning area does not exceed
the stabilization max inclination. During the stabilisation phase, use the spirit level positio‑
ned in proximity to the main controls to check that the maximum inclination of the coupling
with respect to horizontal does not exceed 1°.
Check the route for the presence of persons, holes, overhangs, obstacles, debris and cove‑
rings which may hide holes.
Before entering any high risk areas (refineries, power stations etc.) check accessibility with
plant safety staff.
6.2 PROCEDURES FOR CORRECT USE
Below are the procedures for using the platform as intended by the Constructor. Any use
other than that stated below is prohibited, unless authorised in writing by the Constructor .
6.2.1 S
UMMAY TABLE OF OPERATOR SAFETY STANDARDS
The summary table shown below lists the general safety standards that must be followed
scrupulously by the operator before using the platform.
Remember that a sticker with this table can be found near the controls positioned on the
basket, where it is well visible from the control position.
‑ The elevating platform can only be used by specialised, previously‑trained personnel.
‑ All operations of the extensible structures must be performed from the control position
in the basket. The travel and stabilisation operations must be carried out after checking
that there is complete visibility of the work area. If the machine is controlled from the
ground, keep a minimum distance of 1 metre from the machine.
‑ The instructions contained in the USER AND OPERATION MANUAL that is provided
together with the machine must be followed scrupulously.
‑ Do not exceed the maximum allowed capacity indicated in the USER AND OPERATION
MANUAL and on the basket.
‑ The operator must wear a hard hat and a safety harness appropriately attached to the
relevant anchorage points on the basket.
Remember that the safety harnesses must be checked periodically.
The use of harnesses is compulsory in accordance with local legislation in each indivi‑
dual country. In countries where the law does not require the use of such safety systems,
the employer and/or user is responsible for choosing the system to be used.
X17JR0420113

BOOM LIFT MODELS X17J
JLG
IMPORTANT
IMPORTANTE
‑ Before starting work, the operator must make sure that all the safety devices are in good
working order, and check the efficiency of the main mechanical parts as well as the fuel
and hydraulic oil level.
Never operate on soft, rough, slimy ground or on slopes that exceed the allowable gra‑
dient, in order to ensure that the platform is completely stable.
Make sure that the stabilisers rest on stable HORIZONTAL surfaces.
‑ Level the machine’s chassis perfectly respecting the maximum allowable gradient indica‑
ted in the USER AND OPERATION MANUAL and visible on the spirit level.
‑ Before performing any movement, check that there are no obstacles in the work area and
that no people are in the trajectory.
‑ It is prohibited to carry out work at a distance of less than 5 metres from power lines and
electrical equipment.
‑ It is prohibited to operate in unfavourable atmospheric conditions.
‑ It is prohibited to anchor cables, ropes or the like to the platform and to use the platform
as a lifting device.
‑ It is prohibited to secure ladders, stools or the like to the platform basket to increase the
working height.
‑ Always operate the controls slowly and smoothly, without reversing movements sud‑
denly.
‑ Remember that the basket must only be loaded and unloaded FROM THE GROUND.
‑ Do not use the machine at temperatures below ‑20°C and above 40°C. Do not recharge
the batteries at temperatures below 0°C and above 40°C.
6.2.2 O
PERATOR HOLDING AREAS IN THE BASKET

6.4 USING THE ELEVATING WORK PLATFORM
In the explanations contained in the following paragraphs, it is assumed that the operator
has already read and understood the contents of the previous sections of this manual. The‑
refore, warnings and photos which are already provided in other sections of this document
will be repeated only when absolutely necessary.
The JLG elevating work platforms are suitable for overhead jobs that are performed by an
operator from inside the basket. The platform must be used exclusively by skilled personnel
who are aware of the position and functions of all controls, instruments, indicators, warning
lights and the meaning of the stickers and indications on the machine.
The operator must have understood the platform operating procedures before using it.
Correct use of the platform requires, as well as the presence of the operator (or operators) in
the basket, also the presence of an expert operator on the ground who has to supervise work
and be ready to intervene in case of dangerous situations and for any emergency operations.
This implies that the personnel on the ground must be suitably trained regarding the func‑
tions of the controls and the procedures for use and that they have read the manual.
‑ Failure to comply with even one safety provision may cause injury/damage to the opera‑
tors and/or the machine.
‑ Keep a first aid box and a fire extinguisher near the work area. These must be used in
compliance with the regulations in force.
‑ Do not remain within the platform operating range. The area below must be cordoned
off; it is prohibited to throw objects from or towards the basket.
‑ Wear tight clothing and use all the PPE considered necessary based on the risk analysis
of each individual site (shoes, hard hats, gloves and safety belts).
‑ When the work needs to be performed by two or more persons, before starting always
agree on the correct procedure to follow. Always inform your fellow workers before star‑
ting the procedure.
‑ At low temperatures start the motor and let it run for a few minutes before operating
the platform, so that the hydraulic oil circulates and reaches at least 20°C.

‑ When climbing into the basket, fasten the safety harnesses immediately to the appro‑
priate fixing points before carrying out any operations. Remember that the safety har‑
nesses must be checked periodically.
‑ If the pressure of the stabilisers on the ground exceeds the allowable pressure on the
ground, the support surface must be increased by inserting appropriate plates or a sub‑
strate of stable material (e.g. wood) between the ground and the stabiliser plate. This
material must ensure good friction with the underlying ground and with the stabiliser
plate. Any risk of the machine sliding on the ground must be eliminated.
6.4.1 P
RELIMINARY CHECKS BEFORE STARTING WORK
Carry out the following checks every day before using the machine:
‑ Check that there are no leaks from the hydraulic system. If leaks are present, carry out
the necessary repairs and top up (see the paragraph on maintenance operations). Clean
the area using a solvent or a pressurised solution of water and detergent, taking care to
prevent contact with the electrical parts.
‑ Make sure there is no corrosion and there are no cracks around welded points.
‑ Check the condition and correct tensioning of the track belts (see the paragraph on main‑
tenance operations).
‑ Check that there are no broken, damaged or missing components. Check the correct
tightness of the pin locking bolts and nuts or the safety locknuts. Before using the machi‑
ne replace, tighten and adjust them according to the instructions of the platform manu‑
facturer.
‑ Eliminate debris that may cause fire or breakage, paying particular attention to the
machine control area and the area around the diesel/petrol engine.
‑ Clean the handrails, footboards and control levers removing any oil residues and debris
that may affect safety during the operations, thus putting the operator at risk. Check the
condition of the indicators and electric controls on the control board positioned on the
basket.
‑ Check the condition of the adhesive labels positioned on the machine to ensure they are
easily visible.
‑ Check that the quantity of fuel in the fuel tank is sufficient, in order to avoid useless
down time and emergency descents.
‑ Check the correct operation of all safety devices.

6.4.6 AUTOMATIC WORKING LOAD SELECTION
The elevating platform can work with two different loads: 200 kg or 120 kg. According to the
working load selected, one of the two work areas available on the machine will be enabled.
The working load depends on the position of the jib arm. If this is completely folded the
allowable working load is 200 kg and this is indicated by an icon in position 2 on the radio
control; if the jib is not completely folded the allowable working load is 120 kg and this is
indicated in position 2 on the radio control. If the operator attempts to open the jib with
more than 120 kg in the basket an error message appears in the middle of the display.
If the allowable load limits are exceeded all aerial movements are disabled, an alarm messa‑
ge appears on the radio control and the buzzer sounds. To restore operation, the excess load
needs to be removed.
BOOM LIFT MODELS X17J

X17JR0420113
6.4.7 TRAVEL
The MEWP is a self‑propelled machine able to easily move on any type of ground, over steep
slopes (up to 21°) and, considering the small dimensions, to enter narrow openings. One con‑
dition for travel is that the four stabilisers are lifted from the ground and the machine is in
the transport or stabilisation configuration.
Travel can only be controlled from the position on the ground, always keeping a minimum
distance of 1 metre from the machine during ALL control operations.
When controlling the machine, before travelling make sure that the control position guaran‑
tees a perfect view of the entire machine and EVERY obstacle that may be in the machine’s
trajectory.
If a very precise control of travel movements is required, the motor speed can be reduced by
means of the speed selector button on the remote control.
Pay attention to the overall dimensions of the machine, especially if the stabilisers are not
turned to the transport position.
It is prohibited to get on or off the basket if this is not completely lowered.
The machines are not type‑approved for road travel. The work and travel areas
must be appropriately cordoned off and warning signs displayed according to the
relevant laws in force. The machine must be loaded onto type‑approved vehicles for
transport on public roads.
‑ During control operations, always keep a minimum distance of 1 metre from the machi‑
ne.
‑ It is recommended to travel on flat surfaces with the stabilisers completely lifted and set
in the transport position, so as to reduce the overall dimensions of the machine.
Travel is only allowed with carriage extended to the maximum width whenever possible
in the place of travel. This makes steering easier and increases machine stability.
‑ The 2nd travel speed can only be used for travelling in a straight line on solid and
level ground.

TRAVEL PROCEDURE
Before travelling, proceed as follows:
‑ Check that all instructions previously given in this chapter have been complied with.
‑ Make sure that the ground is compact and can support the weight of the machine.
‑ Check that there are no obstacles in the travel area, considering the overall dimensions
of the machine.
‑ Check that the machine is completely closed and aligned, in the stabilisation or transport
position.
‑ Select the travel speed according to the need and as described above, operating the rele‑
vant button and checking the selection on display.
‑ Operate joysticks 1 and 8 to move the tracks.
‑ If the operator attempts to travel with one or more stabilisers on the ground, an error
message will appear on the display warning the user to raise the stabilisers in order to
allow the machine to travel.
T
RAVELLING ON SLOPES
The maximum slope for travel is shown in the
machine specifications at the beginning of this
manual.
When travelling on inclined surfaces, lower the
stabilisers on the downward side for further
safety in the event of sudden changes in slope.
Do not use the second travel speed to drive on sloping or uneven ground and when not
driving in a straight line.

6.4.8 PARKING THE MACHINE ON A SLOPE OR ON UNEVEN GROUND
When parking the machine on a slope or uneven ground with the stabilisers closed, make
sure that the carriage is in the open position and block the tracks using chocks to prevent the
machine from moving.
‑ Do not use the second travel speed to drive on sloping or uneven ground and when not
driving in a straight line.
6.4.9 S
TABILISING AND LEVELLING THE MACHINE
Once having decided where to park the machine, this can be stabilised and levelled. First of
all check that the surface can support the pressure exerted on the ground by the machine (see
the paragraph on technical specifications) and can contain the overall dimensions of the
machine with stabilisers lowered.
Stabilising the machine on a slope exceeding the allowed limits may cause instability and
consequently harm to or even death of operators or other persons in and around the
working area. Work must only be performed with the machine stabilised at an inclination
under the limits specified by the manufacturer.
‑ Always keep a distance from embankments or ditches that is equivalent to the depth of
such and observe the required safety distance from power lines.
‑ Avoid any contact with objects or persons when lowering the stabilisers.
STABILISATION PROCEDURE
‑ Before moving the stabilisers make sure that:
‑ All instructions provided in this chapter have been complied with.
‑ The ground where the machine is stabilised is compact and can support the weight of
the machine and the maximum possible reaction force on one stabiliser.
NOTE: when working the load on one individual stabiliser can increase greatly due to
the shifting of weight, especially if extension and/or rotation operations are performed.
THIS MUST ALSO BE CONSIDERED WHEN EXAMINING THE GROUND.
‑ There are no obstacles on the stabilisation area and in the trajectory of each individual
stabiliser.
‑ The machine is completely closed and aligned, in the stabilisation position.

The complete closure and alignment is displayed by the arrows on the machine (SEE
PHOTO) and the display of the icon in position 6 on the radio control.
‑ The stabilisers must be lowered from the control position in the basket. Make sure that
visibility of the trajectory of each stabiliser is perfect before moving it.
‑ Select the engine/motor speed as required and check the selection on the display. Always
perform stabilisation at slow speed.
‑ Press and hold the automatic stabilisation button 7 (see the corresponding paragraph). If
the movements are selected with the machine not completely closed and aligned, an
error message will be shown on the display.
‑ Stabilisation will be completed when the machine is in horizontal position with toleran‑
ce of 1° and lifted at least 5 cm from the ground. Correct stabilisation will be confirmed
by the icon in position 5 on the display.
Always check the spirit level and make sure the slope is actually less than 1°.

79
MANUAL STABILISER CONTROL
The manual control of the stabilisers must not be used to stabilise the machine but only to
correct its inclination in the event of stabilisation in difficult conditions. It can also be used to
lower or lift the stabilisers individually in order to increase the stability of the machine, if it is
necessary to transit areas with obstacles or steep slopes.
Pressing the button once shows the screen for the manual operation of stabiliser 1, pressing it
a second time shows the screen for stabiliser 2 and so on until stabiliser 4. Pressing it once
again shows the initial display.
In the manual menu, pressing buttons 1 and 7 raises or lowers the selected stabiliser.
To verify the inclination of the chassis a spirit level is provided on the machine; when the air
bubble it contains is completely inside the green area (see photo below) the machine is in
conditions that allow operation.
Please note that stabilize the machine on slopes greater than allowable limits (see technical
data of the machine) does not permit correct stabilization and is a serious danger for users.
On each stabiliser (see photo below), near the cylinder coupling, there is an orange light.
This light flashes to indicate that the stabiliser is resting on the ground.
X17JR0420113
80
BOOM LIFT MODELS X17J
JLG
Note: IT IS IMPORTANT TO REMIND THAT WHEN THE STABILISERS ARE LOWERED THE CARRIAGE
MUST
ALWAYS BE RAISED FROM THE GROUND.
After using the manual stabiliser control, remember to pressurise the bottom of the stabi‑
liser cylinders. To do this, run an auto‑stabilisation cycle or lower each stabiliser for one
second.
An electronic spirit level on the electronic control board checks that the machine is effectively
level within the allowable tolerance and enables the movements of the aerial part.
Incorrect machine stabilisation does not ensure suitable stability to perform operations. The
Constructor prohibits the use of the machine if it is not stabilised as described in this manual;
the machine overturning may cause serious injury to or even death of its occupants and per‑
sonnel on the ground.
If one of the orange lights positioned on each stabiliser should flash even when the stabi‑
liser is lifted from the ground, stop the machine immediately and call the after‑sales servi‑
ce as this signals the breakage of the corresponding stabiliser microswitch.
If working with the machine stabilised on slippery surfaces (marble, porphyry, polished
cement, smooth damp surfaces etc.) check that the movements of the basket do not cause the
tracks to move. If so, stop the operations and restore the safe operating conditions prescribed
by the manufacturer.stinare le condizioni di sicurezza operative stabilite dal costruttore.
Make sure that the stabilisers rest on horizontal ground. DO NOT REST THE STABILI‑
SERS ON VERTICAL OR INCLINED SURFACES.

6.4.10 AUTOMATIC LOWERING AND RAISING OF THE STABILISERS
The elevating platform is fitted with an innovative self‑levelling system that acts on the stabi‑
lisers and uses the electronic spirit level provided on the main control board.
For the self‑levelling procedure, all the precautions described to this point apply.
Before starting the self‑stabilization make sure that the machine is on a slope less than the
total permitted limit for stabilization (see technical data of the machine) and verify that the
trajectory of the stabilizers is free of obstacles and impediments.
The automatic procedure for levelling the machine extends and retracts the stabilisers,
and consequently moves the machine. Always check that there are no people, animals or
things in the stabilisation area.
• AUTOMATIC LOWERING OF THE STABILISERS
Press and hold button 7 on the radio control.
The success of the self‑levelling procedure is confirmed by an icon displayed on the screen
for several seconds.
At the end of the procedure, always make sure that the spirit level is in the green area. If this
is not the case, contact JLG after‑sales service.

OK
If during lowering one of the stabilisers does not touch the ground, the machine will conti‑
nue to operate the cylinder at the end of its stroke until the motor switches off or the self‑
levelling procedure ends. This situation is normal and indicates that the slope the machine is
situated on exceeds the allowable limit for stabilisation. If at the end of the stabilisation
phase the machine has to be lifted even further from the ground, a new self‑levelling proce‑
dure can be run.
NOTE: using the self‑levelling procedure does not affect the operation of the stabilisers in
manual mode.
• AUTOMATIC RAISING OF THE STABILISERS
Press and hold button 1 on the radio control.
The four stabilisers will start to lower the machine and then will retract completely.
The end of the automatic stabiliser raising cycle is shown on a screen for a few seconds. If
this screen is not shown, the automatic stabiliser raising procedure can still be considered
completed once all the four stabilisers have been completely retracted and consequently the
relevant cylinders are at the end of their stroke.
If problems occur during either of these procedures, immediately release the selected but‑
ton to stop all the movements. Stabilising the machine on a slope exceeding the allowed
limits may cause instability and consequently harm to or even death of operators or other
persons in and around the working area. Work must only be performed with the machine
stabilised at an inclination under the limits specified by the manufacturer.
The elevating platform is considered stabilised when the slope is less than 1° and the tracks
are raised at least 5 cm from the ground. NEVER WORK AT A HEIGHT WITH THE
TRACKS NOT COMPLETELY RAISED FROM THE GROUND.

OVING THE BASKET
Once the machine has been stabilised correctly (check the icon in pos. 5) the basket can be
moved.
• It is prohibited to load material of any type into the basket if the machine is not stabi‑
lised and completely closed. To load and unload the basket the icon in position 6 on
the radio control must be displayed. Loading material into the basket when it is lifted
(e.g. from roofs, balconies etc.) causes the machine to overturn, exposing the occu‑
pants and personnel on the ground to potential risk of death.
• It is absolutely forbidden to use the machine to lift loads both in the basket and con‑
nected in other way to the structure; the machine can lift two persons (80 kg each)
plus 40 kg of tools or using the jib arm one person (80 kg) and 40 kg of tools.
• During machine lowering, near where the upper arms rest on the lower ones, a poten‑
tial shearing risk is created, appropriately signalled by stickers; it is the user’s respon‑
sibility to move any persons away from this area.

• Pay maximum attention to obstacles that may collide with the various parts of the
machine during movement. Before carrying out ANY movement, make sure that
nothing can interfere with ANY part of the machine (branches, protruding parts of
buildings, etc.).
It is prohibited to introduce objects into the basket that provide high resistance to wind
pressure (e.g. large signs) even if they are within the machine’s capacity limits.
PROCEDURE FOR ROUTINE MOVEMENT OF THE AERIAL PART
• Before moving the aerial part, make sure that:
‑ all instructions provided in this chapter have been complied with;
‑ there are no obstacles in the work area;
‑ all the conditions necessary for working at a height are met:
‑ the machine is stabilised and levelled: icon 5 shown on the display,
‑ the weight in the basket is below the maximum allowed,
‑ the radio control is positioned in the basket.
• The aerial part can ONLY be moved from the control position in the basket.
• Select the motor speed as required and check the selection on the display.
• Use the distributor levers in the basket to move the aerial part of the machine according
to the instructions given in the paragraph describing the controls.
The use of the jib arm is only allowed if the working load is less than or equal to 120 kg.
ATTENTION
ATTENZIONE
• If the movements are selected when one of the conditions listed above is not satisfied, an
error message will be shown on the display indicating what conditions are OK and what
are not satisfied (FAIL). If the missing condition is stabilisation, the message will also
indicate what stabiliser is not resting on the ground.
ST1: if OK stabiliser 1 is resting on the ground
ST2: if OK stabiliser 2 is resting on the ground
ST3: if OK stabiliser 3 is resting on the ground
ST4: if OK stabiliser 4 is resting on the ground
INLC: if OK the machine is under the maximum inclination limit
LOAD: if OK, the load is less than the maximum working load allowed
CESTO: if OK, the remote control is in place in the basket
PEDAL: if OK, the footswitch is pushed
OVERLOAD ALARM
If during the basket loading phases the max allowable load is exceeded based on the position
of the jib arm, all movements of the aerial part will be disabled and an error message will be
shown on the display, first on the entire screen and then in position 5.
The alarm will only be reset when the overload is removed. Normal machine operation can
be resumed only then.

BASKET LIFTING ALARM
If when using the machine at a height, for whatever reason, the basket is lifted from its posi‑
tion on the load sensor, an alarm prevents all movements of the machine and the display on
the radio control shows an error message.
The alarm is reset only when the basket is fitted back on the load sensor
ROTATION WITH 1ST‑2ND ARM FOLDED AND 1ST‑2ND ARM DESCENT ON THE
ENGINE
If the turret is rotated with the first or second arm folded or nearly folded, there is the risk of
the first arm hitting against the engine. For this reason, free rotation areas and limited rota‑
tion areas are defined.
LIMITED ROTATION AREA: is an area near the engine where this may be hit by the first
arm.
FREE ROTATION AREA: is the rest of the rotation area that does not coincide with the limi‑
ted rotation area.
These two areas are identified through the combined control of two sensors: a microswitch
that verifies the height of the first and second arm, and a proximity switch mounted inside
the turntable that senses the position of the turret while it turns.
X17JR0420113
BOOM LIFT MODELS X17J
JLG
87
If during operation the arms enter the limited rotation area, the movement being performed
will be stopped and a message on the radio control display will urge the operator to raise the
first and second arm.
In order to be able to continue the movements that have been interrupted, raise the first and
second arm above the height controlled by the microswitch or rotate them in the opposite
direction.

6.4.13 MANUAL LEVELLING OF THE BASKET
The elevating work platform is provided with an automatic basket levelling device that was
designed so that the basket floor is always parallel to the ground independently of the move‑
ments of the arms.
However, due to causes such as leaks and malfunctions, it may be necessary to operate
manually to bring the basket to the optimal position. Proceed as follows to make such adjust‑
ments:
‑ try to move the basket to the travel position by closing the extensible structure comple‑
tely (this, only if the problem occurred while the basket was in a raised position);
‑ only carry out this operation if the basket angle exceeds 10°. If this is not the case, carry
out manual levelling at the minimum possible height, within the limit of 10°. The mini‑
mum height is reached by completely closing the 1st and 2nd arm, extension arm, jib
arm and, as much as possible, the 3rd arm;
‑ unscrew the safety screw, first loosening its lock nut
(two 13 mm fixed spanners are needed to perform this
operation) until releasing the control (see photo);
‑ raise the safety device against the accidental operation of the control and operate it very
gently until the basket is levelled, also lowering the engine speed;
‑ gently release the lever to the neutral point and put the safety screw back in position,
finally tightening its lock nut.
Basket levelling is subjected to some conditions:
‑ it is an exceptional manoeuvre to be performed only in case of slight malfunctions of the
self‑levelling procedure, therefore if the problem occurs frequently, have the basket
checked by an authorised workshop;
‑ the manual levelling control can be operated only from the basket, otherwise the opera‑
tor runs the risk of being injured following contact with moving parts of the machine;
‑ it is absolutely forbidden to use the levelling manoeuvre for purposes other than those
described herein (e.g. to lift objects, to increase the reach of the platform etc.), in order to
avoid serious and even fatal accidents.
ATTENTION
ATTENZIONE
6.5 EMERGENCY MANOEUVRES
The machine was designed considering possible emergency situations such as mechanical
and electrical breakdowns, sudden operator illness etc. In all of these cases the machine can
be operated both from the basket and from the ground so as to bring it back to the transport
configuration or however in such a way as to rescue the occupant/occupants from the basket.
These operations are described below.
Personnel must be present on the ground at all times during platform operation.
The operations described below must be performed in SEQUENCE, starting from the first
and then continuing with the following ones until the last only if the emergency opera‑
tion being performed has not been successful.
6.5.1 B
ASKET EMERGENCY DESCENT CONTROLLED FROM THE BASKET
The basket emergency descent procedure can be controlled from the basket itself only if the
electrical system of the machine is working; proceed as follows:
‑ hold button 4 on the radio control (paragraph 2.1.1 Control position);
‑ check the control through icon 8 on the display (paragraph 4.2.1 Display main screen);
‑ use the lever corresponding to the arm being folded until reaching the required height
(paragraph 2.1.1 Control position);
‑ release button 4.
As descent is due to gravity, the platform and basket cannot be rotated and the telescopic
arm cannot be extended or retracted, therefore the basket is lowered vertically at a distance
from the centre of rotation that depends on the configuration of the machine at the time
when the emergency situation occurred.
If a lever corresponding to a movement without emergency descent is activated, an error
icon is shown on the display:

The message disappears when the lever is released.
6.5.2 O
PERATING THE MACHINE FROM THE EMERGENCY CONTROL POSITION ON THE GROUND IF THE
OPERATOR IS TAKEN ILL
This emergency descent function can be used only if:
‑ the operator in the basket is taken ill.
The sole purpose of the emergency descent from the ground is to aid the operator or opera‑
tors in the basket by bringing them to the ground, all other uses are prohibited.
To perform the emergency descent in the conditions described above, proceed as follows:
a) Move the control distributor selection switch from the distributor in the basket to the
distributor on the ground.
b) If necessary, start the engine using the corresponding button.
c) Move the aerial part of the machine using the manual levers positioned on the distri‑
butor on the ground as described on the sticker placed near them and as specified in
this manual, until the basket carrying the operator reaches the ground.

IMPORTANTE
IMPORTANT
From this position the automatic device for preventing collisions between the first arm and
the engine cannot be activated, so be sure to avoid any contact between the two parts. Negli‑
gent use may cause serious damage to the structure and injury to operators both in the
basket and on the ground.
6.5.3 E
MERGENCY DESCENT IN THE CASE WHERE THE STABILISERS ARE ACCIDENTALLY RETRACTED
While it is recommended to follow the instructions provided in the paragraph on stabilising
the machine, for various reasons one of the stabilisers may lose contact with the ground,
thus changing the angle of the machine or causing a foot plate to lift from the ground. If this
occurs when the machine is at a height, movements are stopped and disabled immediately.
To restore operation of the platform (close the aerial part and then stabilise the machine
again) the electrical emergency descent function can be used, which involves only the return
of the aerial part.
If this is not possible due to the presence of objects that interfere with the operation, person‑
nel on the ground can allow the operator in the basket to close the machine.
The operators on the ground can bypass the machine’s safety devices and allow the operator
in the basket to close the machine or allow the manual operations as described in the pre‑
vious paragraphs, in order to bring the operator back to the ground.
Read the instructions provided below before performing the operation as it is potentially
dangerous for the operator in the basket.
Proceed as follows:
‑ Open the electrical components compartment.
‑ Position the emergency key on the electrical components compartment, removing it from
the side where this is lead‑sealed (see photo).

‑ Once the machine is closed, release the key, remove it and put it back in its original posi‑
tion.
‑ The electronic control board records every time the safety device bypass key is used.
Control the machine ONLY carrying out operations that allow the machine to be closed:
first/second arm folding, extension arm in, jib arm folding. The third arm can be rotated
and lowered only with the extension arm completely retracted.

6.5.4 EMERGENCY DESCENT CONTROLLED FROM THE GROUND IN THE EVENT OF SUDDEN OPERATOR
ILLNESS
, WITH THE MOTOR RUNNING AND ELECTRICAL SYSTEM FAULT
This emergency descent function is used only if the operator feels ill while the motor is run‑
ning and the electrical system has broken down or if it is not possible to perform the pre‑
vious emergency operations.
Any movement of the arms must be performed AT THE MINIMUM SPEED POSSIBLE.
‑ Remove the cap from the solenoid valve (the external lead seal
breaks automatically when the cap is unscrewed and removed)
and close it manually by pressing and turning the underlying
knob: the internal wire sealed with lead breaks automatically and
closes the solenoid valve.
‑ Enable the aerial part by screwing completely the special flywheel
(see photo), located under the distributor protection casing on the
carriage.
‑ Act on the switch thus enabling the emergency distributor from
the ground.
‑ Use the distributor levers to enable the desired movement fol‑
lowing the instructions to be found on the label attached near the
controls.
The sequence of movements is the following:
‑ retract extension arm
‑ fold jib arm
‑ fold first‑second arm
‑ fold third arm.
The sole purpose of the emergency descent from the ground is to bring the basket to the
ground in order to assist the operator, all other uses are prohibited.
During this procedure it is prohibited to perform any operations other than those described
above, for example to extend the telescopic arm or the jib arm, to move the stabilisers and
generally to perform operations that may cause the machine to lose stability.

This emergency descent function is only used if the electrical system and motors break down,
meaning one of the previous emergency operations cannot be performed.
The emergency descent from the ground can only be carried out using the hydraulic hand pump;
to move the basket, pump oil manually and simultaneously use the ground controls for the arm
movements.
IF THIS DEVICE HAS BEEN USED TO MOVE THE MACHINE, BEFORE USING THE MACHINE AGAIN TO
WORK AT A HEIGHT IT IS COMPULSORY TO SET IT IN THE TRANSPORT CONFIGURATION
(MACHINE
