INTRODUCTION

■ INTRODUCTION

This handbook provides information for a safe and
proper operation and maintenance of the machine.

STRICTLY COMPLY WITH THE INSTRUCTIONS

GIVEN IN THIS HANDBOOK!
READ AND UNDERSTAND THIS HANDBOOK
BEFORE STARTING, USING AND CARRYING

OUT ANY OPERATION WITH AND ON THE

MACHINE.

The handbook is divided into seven sections:

Sect. A GENERAL INFORMATION
Sect. B SAFETY
Sect. C OPERATING INSTRUCTIONS
Sect. D MAINTENANCE
Sect. E TROUBLESHOOTING
Sect. F OPTIONAL ATTACHMENTS
Sect. G TABLES AND ENCLOSURES

Section A contains general concepts that are decisive
for the knowledge of the main parts of the machine.
It also contains all necessary data for a correct
identification of the machine, the technical features of
the machine, etc.

Section B is especially addressed to the personnel,
who shall operate, repair and service the machine, and,
in case of companies with a wide fleet of machines, to
the safety responsible.
It describes the essential compulsory qualities of the
personnel in charge and other important information
for the safety of persons and things.

Sections are subdivided into chapters and paragraphs
that are numbered progressively.

The quickest way to look for an information is the
reference to the general index or the titles of the single
chapters and paragraphs that represent keys for an
easy consultation.

Take care of this handbook and keep it in an
accessible place within the machine, even
after its reading, so that it will always be
within reach if in doubt.

If you are unsure about anything, please address to
GENIE Assistance Service or to your agent/dealer:
addresses, phone and fax numbers are printed in
the cover and in the title-page of this manual.

IMPORTANT

Any difference between the contents of this manual
and the real functional character of the machine
can be attributed to either a machine manufactured
before the issue of this manual or to a manual going
to be updated after some changed effected on the
machine.
Always contact GENIE Assistance Service for any
updated version of this manual and any additional
information.

Section C is mainly addressed to the operators who
operate the machine. This section illustrates all control
devices.
Additionally, it contains the main use instructions -i.e.
engine starting, machine parking, machine storing.

Section D is addressed to the maintenance responsible
and the servicemen.
The section describes the maintenance schedule and
the relevant intervals.

Section E deals with the failure diagnostics.
Section F makes a list of the main interchangeable

attachments that can be coupled to the machine:
dimensions, weight, application field and limits of use.

Section G contains tables and various enclosed
documents like load charts, wiring diagrams, hydraulic
schemes, torque wrench setting table, etc.

■ SYMBOLS

GTH-3713 - GTH-4017 - GTH-4514

INTRODUCTION

When using the machine, operators could have to face
some situations requiring special care and particular
knowledge.

When these situations involve the safety of operators
or bystanders, the machine efficiency and proper
utilisation, this handbook stresses these specific
instructions by means of SPECIAL SYMBOLS.

There are six special (or safety) symbols in this manual,
always combined with keywords that class the situations
according to their danger degree.

The symbols are always followed by a text explaining
the situation taken into account, the attention to be
paid to such situation, the method and the behaviour to
be adopted. When necessary, it stresses prohibitions
or supplies instructions to prevent dangers.

Sometimes, it can be followed by illustrations.

We list below the special (or safety) symbols according
to the relative seriousness of the hazard situation:

DANGER

Draws the attention to situations that involve your
own as well as the others’ safety and that can result
in serious or lethal injury.

ATTENTION

Draws the attention to situations that involve the
machine efficiency.

IMPORTANT

Draws the attention to important technical
information or practical advice that allows for a
safer and more efficient use of the machine.

PROTECT THE

ENVIRONMENT

Draws the attention to important environment­related information.

WHEN READING THIS MANUAL, PAY THE
GREATEST ATTENTION TO THESE SPECIAL
SYMBOLS AND THE EXPLANATION OF THE

SITUATIONS THEY EMPHASIZE.

ELECTRICAL

DANGER

Draws the attention to situations that involve your
own as well as the others’ safety and that can result
in serious injury or lethal injury.

CAUTION

Draws the attention either to situations that involve
your own as well as the others’ safety and that can
result in minor or moderate injury or to situations
that involve the machine efficiency.

ATTENZIONE

E’ vietato utilizzare la macchina e gli accessori senza prima aver
letto e compreso le norme di utilizzo e di sicurezza contenute nel
manuale di istruzioni.
Il mancato rispetto delle norme di utilizzo e di sicurezza puo’ causare
pericolo grave all’operatore e a terzi.
Le istruzioni sono consegnate con la macchina e copie aggiuntive
possono essere richieste al rivenditore o direttamente a Terexlift.
L’operatore è responsabile del rispetto delle norme sopra riportate
non sollevare carichi se la macchina appoggia su terreno
instabile o inclinato.
Non sollevare mai carichi superiori a quelli indicati in tabella.
Non sono ammesse manovre di sollevamento con macchina
in movimento.
Prima di abbandonare il posto di manovra:

- abbassare eventuali carichi sospesi

- portare in posizione di riposo gli organi di comando del

braccio

- posizionare la leva marcia avanti-indietro in folle, inserire

il freno a mano e arrestare il motore.
Norme per l'utilizzo di macchine dotate di stabilizzatori
E’ vietato utilizzare gli stabilizzatori se il carico è già sollevato:
gli stabilizzatori servono solamente ad aumentare la stabilità
della macchina.
L'uso scorretto degli stabilizzatori può causare il ribaltamento
della macchina.
Una apposita spia sul cruscotto indica che gli stabilizzatori
sono abbassati: accertarsi che la spia sia accesa.
Prima di sollevare il carico livellare la macchina controllando

GENERAL INFORMATION

A-3 ALLOWED USE

■ A-3.1 ALLOWED USE

The handlers have been designed and manufactured
for lifting, handling and transporting agricultural or
industrial products by means of specific attachments
(see section F) manufactured by TEREXLIFT srl.

Any other use is considered contrary to that established
and, therefore, improper.

The compliance with and the strict respect of the
operation, maintenance and repair conditions, indicated
by the Manufacturer, represent an essential part of the
allowed use.

The handler must be used and serviced only by
operators knowing its characteristics and the safety
procedures in depth.

It is also essential to comply with the safety at work
legislation, the precautions concerning safety and
industrial medicine as well as the local and national
road traffic regulations.

ATTENTION

Effecting changes or carrying out interventions on
the machine other than those of routine
maintenance is expressly forbidden. Any
modification of the machine not carried out by
GENIE or an authorised assistance centre involves
the automatic invalidation of the conformity of the
machine to the Directive 98/37/EC.

■ A-3.2 IMPROPER USE

Improper use means a utilisation of the handler
following working criteria that do not comply with the
instructions of this manual, and that, in general, may
result in risks for both operators and bystanders.

DANGER

We list below some of the most frequent and
hazardous situations of improper use:

- Carrying passengers on the machine

- Not strictly complying with the operation and
maintenance instructions of this handbook

- Working beyond the handler working limits

- Working on unstable edges of ditches

- Driving crosswise on slopes or hills

- Working during a storm

- Working on steep slopes

- Using attachments other than those
recommended

- Using attachments not approved or directly
manufactured by Terexlift

- Working in potentially explosive areas

- Working in confined and non-ventilated
environments.

■ A-3.3 RESIDUAL HAZARDS

Although the machine has been designed and
manufactured according to the latest technology and
all expected hazards have been eliminated, some
operations performed by the machine operator can
result in potentially hazardous situations. Among them:

• Hazards deriving from a too high work or transfer
speed in relation to the load handled or the ground
condition of the jobsite.

• Hazards deriving from work procedures adopted
during the check or replacement of a block valve
(residual pressure - uncontrolled movements).

• Hazards deriving from work procedures adopted
while disassembling parts of the machine -e.g. the
cylinders, without supporting mobile parts suitably
(risk of uncontrolled fall of the mobile part).

• Hazard deriving from an accidental overturning of
the machine in the event the operator has not
fastened the safety belts.

GENERAL INFORMATION

■ A-4.2

Hydrostatic transmission unit

This unit consists of parts which drive the machine
shifting, and namely:

-a variable displacement pump connected to the

thermal engine by an elastic joint

-a variable displacement engine applied to the

gearbox

-a hydraulic oil filter, placed on the injection line from

the tank

-a water/oil heat exchanger to cool the circuit down.

Reduction gear/Two-speed gearbox

Reduction gear/gearbox with two speeds, namely
working speed and travel speed, to be selected by the
special pushbutton located in the cab. The selection
of the gear is allowed only when the machine is
stationary. Motion is transmitted from the gearbox to
the front and rear axles, fitted with differential gear,
through two Cardan shafts.

Steering axles/(front and rear) differential gears

The differential axles transmit the motion to the wheels.
The automatic locking differential acting on the rear
axle enables the machine to move also on low grip
grounds.
Both axles of the GTH-3713 are the steering type and
the rear axle is also the sprung type.
On the contrary, in mod. GTH-4017 - GTH-4514, both
axles are steering and oscillating. Two hydraulic
cylinders operated from the driving cab control the front
axle oscillation to keep the machine balanced.
When the high speed is engaged, only the front wheels
are allowed to steer and the rear oscillating axle (only
for mod. GTH-4017 - GTH-4514) is automatically
locked in position (proximity switch) when the boom is
raised 40° above the horizontal.

DESCRIPTION OF THE MAIN COMPONENTS

Boom hydraulic circuit

It consists of a pump connected to the thermal engine
which, through a valve, distributes oil to the hydraulic
drive and a distributor for the following functions:

- boom lifting/lowering

- telescopic boom extension/retraction

- attachment rotation

- machine swaying

- attachment locking

- outrigger operation.

Service hydraulic circuit

It consists of a pump connected to the thermal engine
and dispensing oil to the brake pump and the hydraulic
motor driving the heat exchanger fan.

Brake circuit

The brake system is the multidisc type in oil bath, with
self-adjustment, built in the front and rear axle and
acting on every wheel. The pedal directly acts on the
brake pump which delivers oil to the blocking cylinders
through a line with a pressure accumulator.
In models GTH-4017 - GTH-4514, the parking brake
is the negative type and acts on the braking unit of the
front axle. This brake activates when the engine is
stopped or when the brake lever on the left of the
driver’s seat is pulled.

Driving cab

Type-approved driving cab in compliance with
standards ISO 3449 and EN 13510 (ROPS and FOPS).

■ A-4.3 OPTIONAL ACCESSORIES

The machine can be fitted with a wide range of optio­nal accessories: please address to GENIE sales
network.

Tyres

The machine is equipped with tyres suitably sized for
the maximum load allowed on the handler.
When worn, they shall be replaced with new ones
having the same dimensions and loading capacity.

Overload warning system

The overload warning system installed on the vehicle
enables the operator to work under absolute safety
conditions. A bar with green, yellow and red LEDs
indicates the percentage of load applied with respect
to the maximum payload of the machine. When the
2nd red LED comes on, the machine movements are
blocked, except for the boom retraction under safe
conditions.

B-3 SAFETY PRECAUTIONS

■ B-3.1 JOB SITE

Always take into account the features of the job site
where you are going to work:

• Always examine the working area and compare it
with the machine dimensions in the different
configurations.

ELECTRICAL

DANGER

Pay the greatest attention to overhead electric
lines.
Always keep at a minimum safe distance from the
telescopic boom and the lifted load. Electrical
hazards!

DANGER

DEATH OR INJURY CAN RESULT FROM
CONTACTING ELECTRIC POWER LINES.

ALWAYS CONTACT THE ELECTRIC POWER LINES
OWNER. THE ELECTRIC POWER SHALL BE
DISCONNECTED OR THE POWER LINES MOVED
OR INSULATED BEFORE MACHINE OPERATIONS
BEGIN

POWER LINE VOLTAGE REQUIRED CLEARANCE

0a 50 kV 10 ft 3.00 m

50 a 200 kV 15 ft 4.60 m
200 a 350 kV 20 ft 6.10 m
350 a 500 kV 25 ft 7.62 m
500 a 750 kV 35 ft 10.67 m
750 a 1000 kV 45 ft 13.72 m

• Look for the best route to the job site.

• When the machine is running, nobody can enter
its working range.

• While working, keep the working area in order.
Never leave objects scattered: they could hinder
the machine movements and represent a danger
for personnel.

DANGER

Do not at any time use the machine during a storm.

CAUTION

Make sure the machine (wheels and stabilisers)
rests on a firm ground to prevent hazardous
unstable conditions.
If the ground is not firm enough, position some
supporting planks under the stabilisers or the
wheels. These plates must grant a specific pressure
of 1.2 to 1.5 kg/cm2 (500x500mm plates are
sufficient).

SAFETY

■ B-3.2 GETTING READY TO WORK
Before any operation, following precautions should be
taken:

• First of all, make sure that the maintenance
interventions have been carried out with care
according to the established schedule (see section

D - Maintenance).

CAUTION

Set the machine to working configuration and sway
it. Use the special inclinometer to the right of the
driving place to check that the machine is level
before operating it.

• Ensure you have enough fuel to avoid a sudden
stop of the engine, especially during a crucial
manoeuvre.

• Clean instruments, data plates, lights and the cab
windscreen thoroughly.

• Check the correct functioning of all the safety
devices installed on the machine and in the job
site.

• In case of troubles or difficulties, inform the foreman
at once. Never start working under unsafe
conditions.

• Do not carry out any repair work in a makeshift
way to start working!

• When entering/leaving the cab or other raised
parts, always face the machine; never turn the
back.

• When carrying out operations at hazardous heights
(over 1.5 meters from the ground), always use
type-approved safety belts or fall preventing
devices.

• Do not enter/leave the machine while it is running.

• Do not leave the driving place when the machine
is running.

• Neither stop nor carry out interventions under or
between the machine wheels when engine is
running. When maintenance in this area is required,
stop the engine.

■ B-3.3 DURING WORK OR MAINTENANCE
During work, and especially maintenance, always pay
the greatest attention:

• Do not walk or stop under raised loads or machine
parts supported by hydraulic cylinders or ropes
only.

• Keep the machine handholds and access steps
always clean from oil, grease or dirt to prevent falls
or slips.

Page B-5

Document 57.0004.4200 - 11/2004

• Do not carry out maintenance or repair works
without a sufficient lighting.

• When using the machine lights, the beam should
be oriented in order not to blind the personnel at
work.

• Before applying voltage to electric cables or
components, check their connection and proper
functioning.

• Do not carry out interventions on electric
components with voltage over 48V.

• Do not connect wet plugs or sockets.

• Plates and hazard warning stickers shall never be
removed, hidden or become unreadable.

GTH-3713 - GTH-4017 - GTH-4514

• Except for maintenance purposes, do not remove
safety devices, shields, protection cases, etc.
Should their removal be necessary, stop the engine,
remove them with the greatest care and always
remember to refit them before starting the engine
and using the machine again.

• Before any maintenance or repair work, stop the
engine and disconnect the batteries.

• Do not lubricate, clean or adjust moving parts.

• Do not carry out operations manually when specific
tools are provided for this purpose.

• Absolutely avoid to use tools in bad conditions or
in an improper way i.e. pliers instead of adjustable
wrenches, etc.

• Before carrying out operations on hydraulic lines
under pressure or disconnecting hydraulic
components, ensure the relevant line has been
previously depressurised and does not contain any
hot fluid.

SAFETY

DANGER

Any intervention on the hydraulic circuit must be
carried out by authorised personnel.
The hydraulic circuit of this machine is fitted with
pressure accumulators. You and others could be
seriously injured if accumulators are not completely
depressurised.
For this purpose, shut the engine down and step
on the brake pedal 8÷10 times.

• Neither smoke nor use open flames in areas subject
to fire dangers and in presence of fuel, oil or
batteries.

Page B-6

Document 57.0004.4200 - 11/2004

GTH-3713 - GTH-4017 - GTH-4514

SAFETY

• Do not leave fuel cans or bottles in unsuitable
places.

• Do not empty catalytic mufflers or other vessels
containing burning materials without taking the
necessary precautions.

• Carefully handle all flammable or dangerous
substances.

• Do not tamper with fire-extinguishers or pressure
accumulators: explosion hazard!

• After any maintenance or repair work, make sure
that no tool, cloth or other object has been left
within machine compartments, fitted with moving
parts, or where suction and cooling air circulates.

• When working, do not give instructions or signs to
several people at the same time. Instructions and
signs must be given by one person only.

• Always pay the due attention to the instructions
given by the foreman.

• Never distract the operator during working phases
or crucial manoeuvres.

• Do not call an operator suddenly, if unnecessary.

• Do not frighten an operator or throw objects by no
means.

• After work, never leave the machine under
potentially dangerous conditions.

B-4 SAFETY DEVICES

DANGER

Several safety devices have been fitted to the
machine. They must never be tampered with or
removed (see chap. A-3.5).

Regularly check the efficiency of such devices (see

check card, chap. G-5).

In case of faults, stop working immediately and
proceed in replacing the defective device.

For the checking procedures, read chap. D-3.15.

■ B-5 LOAD LIMITING SYSTEM

The load limiting system has been developed to help
use the machine in safety conditions and alerting with
visual and sound messages when the machine is
nearing a danger zone.
However this device cannot replace the experience of
the Operator. It is up to the user to adopt the necessary
safety measures to work in safety conditions.

OPERATING INSTRUCTIONS

C-3.4 CONTROL LEVER

The handlers are equipped with a multipurpose electro­proportional lever that allows operating all machine
movements.

When shifted to one of the four directions (right/left,
forward/back), it controls the boom lifting/lowering and
the forward/back pitching of the attachment frame.
Pressing buttons  or , you move the boom
telescopes out and in and you lock/unlock the
attachment fitted to the machine.

It is also equipped with an intentional control button
 that must be pressed and held in position until the
movement is completed.
If the button is not pressed down, the lever, though

operated, does not perform any function.

IMPORTANT

Seize the control lever correctly and move it gently.
The motion speed of the actuators depends on the
lever position: a small motion results in a slow
motion of the actuators; vice versa, a full range
motion of the lever corresponds to the max. speed
of the actuator.

CAUTION

The control lever shall be operated only when
correctly seated in the driving place.

CAUTION

Before operating the control lever, make sure that
nobody is within the working range of the machine.

■ C-5.2.3 Alarm codes and resetting

DANGER

Before using the machine, make sure that the first
green LED of the overload warning system is ON.
The overload warning system must not be used to
check the load going to be lifted: it has only been
designed to signal possible unbalances of the
machine along its motion axis.
Such unbalances may also be caused by an abrupt
operation of the levers during the load handling. If,
during work, several indicators light up, operate the
levers more smoothly.

The limiter has diagnostic facilities to aid in the
identification of failures of the transducers, breakages
of the cables or defects of the electronic system.
When a failure is signalled, the limiter enters the safety
mode blocking any dangerous manoeuvres. Lights 5,
8 and 10 start flashing, the buzzer start sounding and
an error message is shown on the display.

The meaning of the error messages is shown in Section

E “Faults and Troubleshooting”.

■ D-3.13 SHAFTING ALIGNMENT

During operation, the alignment of the front and rear
axles of the machine can be subject to variations. This
can depend on an oil blow-by from the steering control
circuit, or on a steering of both axles when front and
rear wheels are not perfectly aligned.

To fix this problem, rather than checking the alignment
visually, follow the procedure below:

1) Move to a solid and level ground

2) Set the steering selection switch 12 to “four-wheel
steer” (pos. 2)

3) Rotate the steering up to its stop (either to the right

or to the left)

4) Set the steering selection switch to “two-wheel
steer” (pos. 0)

12

5) Rotate the steering up to its stop (turn in the same

direction as above)

6) Reset the steering selection switch to “four-wheel
steer” (pos. 2)

7) Rotate the steering (to the side opposite to point
so that the rear axle reaches its stop

8) Reset the steering selection switch to “two-wheel
steer” (pos. 0)

9) Rotate the steering (to the same side as in point 7)
so that the front axle reaches its stop

10) Reset the steering selection switch to “four-wheel
steer” (pos. 2)

Now the wheels should be re-aligned.
