1. INTRODUCTION
This Use and Maintenance Manual provides general instructions concerning the complete range of machines indicated on
the cover. Therefore, the description of their components, as well as control and safety systems, may include parts not
present on your machine since supplied on request or not available. In order to keep pace with the technical development
AIRO-Tigieffe s.r.l. reserves the right to modify the product and/or the use and maintenance manual at any time without
updating the units already delivered.
Legal aspects
Within EU (European Union) member countries the machine is delivered complete with:
▪Use and Maintenance manual in your language.
▪CE mark applied on the machine.
▪CE conformity declaration.
▪Guarantee certificate.
▪Declaration of internal testing.
Only for Italy:
▪Instructions on commissioning declaration with INAIL and on the application for the first periodic check on the INAIL
portal.
It is to be noted that the Use and Maintenance Manual is an integral part of the machine and a copy of this, together with
copies of the documents certifying that the periodical checks have been carried out, must be kept on board in its suitable
container. In the event of a transfer of ownership the machine must always be provided with its use and maintenance
manual.
The legal obligations of the owner of the machine vary according to the country of commissioning. It is therefore
recommended to inquiry about the procedures in force in your country from the boards responsible for industrial safety.
This manual contains a final section called "Check register" for a better filing of documents and recording of any
modifications.
1.1.2.1. Declaration of commissioning and first check
In ITALY the owner of the Aerial Platform must notify the use of the machine to the local competent INAIL and submit it to
periodical compulsory checks. The first of such checks is performed by the INAIL within sixty days from a request being
made. In the event of such time passing without the inspection being made, the employer can call in the ASL (Local Health
Unit) or qualified public or private services. Subsequent checks are made by the already-mentioned parties within thirty
days from a request being made. In the event of such time passing without these checks being made, the employer can
call in qualified public or private services. The checks are on a payment basis and the employer (machine owner) will be
charged for them. For these checks, the territorial inspection boards (ASL/USL or ARPA) and INAIL can be supported by
qualified public or private services. Authorized private entities acquire the status of public service representatives and
respond directly to the public structure that owns the function.
For the commissioning declaration in Italy, it is necessary to login to the INAIL portal. Follow the instructions delivered
together with other documents during the machine delivery, as well as the information about the portal.
The INAIL will assign a serial number and when the First Check is performed the “technical identification sheet” will be
completed indicating only the details obtained from the already-operating machine or from the instruction manual. This
document will form an integral part of the machine documentation.

Use and maintenance –A18 JRTD PLUS A18 JRTH PLUS A18 JRTE PLUS series
Page 8
1.1.2.2. Subsequent periodic checks
Yearly checks are compulsory. In Italy the Aerial Platform owner must apply for a periodical check - by registered letter -
to the local competent inspection board (ASL/USL or ARPA or other qualified public or private services) at least twenty
days before the expiry of the year from the last check.
NB: If a machine without a valid control document should be moved in an area outside the competence of the usual
inspection board, the owner of the machine must ask the inspection board, competent for the new territory where the
machine is to be used, for the annual check.
1.1.2.3. Transfers of ownership
In case of transfer of ownership (in Italy), the previous owner of the MEWP must notify the unavailability of the machine
by connecting to the INAIL portal.
The new owner will have to retrieve the registration data of the MEWP from the same INAIL portal in order to continue to
subject the machine to the periodic inspections required by law.
The new owner must in any case have the following documentation released by the previous owner:
▪Declaration of conformity issued by the manufacturer.
▪Declaration of commissioning carried out by the first owner.
▪Last periodic check result.
▪Instructions manual.
The employer must ensure that the workers appointed to use the equipment are adequately and specifically trained so
they are able to use the Mobile Elevating Work Platform in a proper and safe way and also avoid the risks caused by other
people.
Tests carried out prior to delivery by the manufacturer
Before being placed on the market, each MEWP undergoes the following tests:
▪Braking test.
▪Overload test.
▪Operating test.
Intended use
The machine described in this use and maintenance manual is a self-propelled aerial platform intended for lifting persons
and materials (equipment and work materials) in order to carry out maintenance, installation, cleaning, painting, de-
painting, sand-blasting, welding operations, etc.
The max. capacity allowed (which varies according to the model –see paragraph “Technical features”) is divided as
follows:
▪80 Kg for each person on board.
▪40 Kg for equipment.
▪The remaining load is represented by the material being worked.
In any case NEVER exceed the maximum capacity allowed as indicated in paragraph "Technical features”. Persons, tools
and work materials can be loaded on the platform only from the access position (platform lowered). It is absolutely
forbidden to load persons, tools and work materials on the platform when it is not in access position.
All loads must be positioned inside the platform. Do not lift loads (even if complying with the maximum capacity allowed)
hanging from the platform or lifting structure.
Do not carry large-sized panels since they increase the resistance to wind force thus causing the machine to overturn.

Use and maintenance –A18 JRTD PLUS A18 JRTH PLUS A18 JRTE PLUS series
Page 9
While the machine is being displaced with lifted platform, no horizontal loads can be loaded onto the platform (operators
on board are not allowed to pull wires or ropes, etc.).
An overload controller stops the operation of the machine if the load on the platform exceeds by 20% approx. the nominal
load (see chapter "General use rules”) and platform is lifted.
The machine cannot be used in areas where road vehicles operate. Always surround the working area by means of suitable
signs when the machine is used in public areas.
Do not use the machine to tow trucks or other vehicles.
All types of machine use other than those for which it was designed must be approved in writing by the machine
manufacturer following a specific request on the part of the user.
Do not use the machine for purposes other than those for which it was designed, except after
making a request and having obtained written permission in this sense from the manufacturer.
The mobile elevating work platforms are not designed by taking into account the risks of the “leaving at height” because
the only access position considered is when the platform is completely lowered. For this reason, this activity is formally
prohibited.
However, there are exceptional conditions in which the operator needs to access or leave the work platform not in the
access position. This activity is commonly referred to as 'leaving at height'.
The risks connected to the “leaving at height” do not depend exclusively on the MEWP (mobile elevating work platform)
characteristics; a specific risk analysis carried out by the employer can authorize this specific use by taking into account:
▪The working environment characteristics.
▪The absolute prohibition to consider the work platform as a anchoring point for people working outdoors.
▪The use of the machine at xx% of its performance to avoid that additional forces created by a specific operation
or bending of the structure move away the access zone from the unloading zone. Provide for some prior testing
in order to define these limitations.
▪Provide for a specific evacuation procedure in case of emergency (for example: an operator always on the work
platform, one at the ground control panel while a third operator leaves the lifted platform ).
▪Provide for a specific training of the staff both as operator and transported staff.
▪Equip the unloading zone with all the devices that are necessary to avoid the risk of fall of the staff that
accesses/leaves the platform.
What said above is not a formal authorization of the manufacturer for the “leaving at height”, but it wants to supply
information to the employer - who is fully responsible for that - which can be useful for the planning of this exceptional
activity.
Description of the machine
The machine described in this use and maintenance manual is a mobile elevating work platform equipped with:
▪Motorized chassis equipped with wheels.
▪Hydraulically driven rotating turret.
▪Articulated boom operated by hydraulic cylinders (the number of articulations and cylinders varies according to
machine model).
▪Operator platform (the max. capacity varies according to the model - see chapter "Technical features”).
The chassis is motorized to allow the machine to move even when the platform is lifted (see “Use instructions”). The
machines can be delivered with the following drive and steering features:
▪Four drive wheels, of which two steering and two fixed.
▪Four steering and drive wheels.
Furthermore, to all the above combinations, it is possible to associate, optionally, a self-locking oscillating axle.
All drive wheels are equipped with hydraulic parking brakes, positive logic type (when drive controls are released brakes
are automatically activated).

Page 10
The turret rests on a turntable fixed to the chassis and can be oriented (rotated) by 355° non-continuous around the
central axle of the machine by means of irreversible endless screw.
The lifting system, with articulated boom, can be divided into three main structures:
▪The first, with vertical extension, consists of a “double parallelogram” system named “pantograph”.
▪The second, consists of a lifting boom with telescopic extension.
▪The third, consists of a terminal boom called "Jib" (the Jib is fixed on the standard machine, and swivels 180° on
the machines with platform size 800x1400 mm).
Such lifting structures are driven by 4 double-acting hydraulic cylinders:
▪One cylinder for the “pantograph” extension.
▪One cylinder for the boom extension.
▪One cylinder for the extension/retraction of the telescopic boom.
▪One cylinder for the “jib” extension.
The hydraulic cylinders that move the articulated structure are are provided with over-center valves directly flanged on
them. These devices allow the booms to remain in position even if one of the supply tubes accidentally breaks.
The platform, hinged to the end of the “jib”, can be rotated by 180° totally (90° on the right and 90° on the left) by means
of a rotary actuator fitted with over-centre valve. It is fitted with rails and kickplates of prescribed height (the rails height 
1100 mm; the kickplate height 150 mm; in the access area the kickplate height is 100 mm). There is a ladder hinged to
the platform that can be lifted by the operator during normal platform work to limit the size of the platform.
The platform levelling is automatic and is ensured by mechanical ties and two cylinders in closed circuit. The manual level
compensation is possible by acting on the relevant control only with completely lowered booms (and with “Jib” inclination
ranging between +10° and –70° with respect to the horizontal axis).
