Use and Maintenance Manual – A21 J A23 J Series Page 6
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 our
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.
1 1 Legal aspects
1 1 1 Delivery of the machine
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 declaration of conformity.
Guarantee certificate.
Only for Italy:
Declaration of commissioning to INAIL.
List of local INAIL departments.
Declaration of internal testing.
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.
1 1 2 Declaration of commissioning, first check, further periodical checks and transfers of ownership
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 ITAL 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. The qualified
private institutes acquire the qualification of responsible for the public service and refer directly to the public structure that controls
this function.
To declare the commissioning of the machine in Italy, send the form that is supplied together with other documents upon machine
delivery, by registered letter with advice of receipt.
The INAIL will assign a serial number when the First Check is performed before completing the “technical identification sheet” on
which it indicates only the details obtained from the already-operating machine or obtainable from the instruction manual. Such
document shall form an integral part of the machine documentation.

Use and Maintenance Manual – A21 J A23 J Series Page 7
1 1 2 2 Further periodical checks
early checks are compulsory. In Italy the owner of the Aerial Platform must apply for a periodical check by sending a registered
letter to the local competent inspection board (ASL/USL 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 new owner of the Aerial Platform must notify the ownership of the machine to the local
competent inspection board (ASL/USL or other qualified public or private services) by enclosing a copy of:
Declaration of conformity issued by the manufacturer.
Declaration of commissioning carried out by the first owner.
1 1 3 Operator training and information
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.
1 2 Tests performed before delivery
Before being placed on the market, each MEWP undergoes the following tests:
Braking test.
Overload test.
Operating test.
1 3 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.
Any remaining load is represented by the work materials.
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 cage. 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.
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.

Use and Maintenance Manual – A21 J A23 J Series Page 8
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
1 3 1 Leaving at height
The work elevating 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 forbidden.
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 normally defined as “leaving at height”.
The risks connected to the “leaving at height” do not depend exclusively on the PLE (work elevating 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 an anchoring point for people working outdoors.
The use of the machine at xx% of its performances 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 tests in order to define
these limitations.
Provide for a specific evacuation procedure in case of emergency (for example: an operator always on the 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.
1 4 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 driving wheels, of which two steering and two fixed.
Four steering and driving wheels.
Furthermore, to all the above combinations, it is possible to associate, optionally, a self-locking oscillating axle.
All driving wheels are equipped with hydraulic parking brakes, positive logic type (when drive controls are released brakes are
automatically activated).
The turret rests on a turntable fixed to the chassis and can be oriented (rotated) by 360° continuously around the central axle of
the machine by means of geared motor with built-in hydraulic brake.
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 the terminal boom named “Jib”.
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 (for A23 J two systems of chains for extraction and
retraction of the last extractable boom are also supplied).
One cylinder for the “jib” extension.

Use and Maintenance Manual – A21 J A23 J Series Page 9
The hydraulic cylinders which move the articulated structure (except for the boom inclination sensor cylinder) are provided with
over-centre valves directly flanged on the same. 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 guardrails and toe boards of prescribed height (the guardrails height ≥
1100 mm; the toe boards height ≥150 mm). 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 with respect to the horizontal axle ranging between +10° and –70°).
1 5 Control panels
The machine is equipped with two control panels:
On the platform for normal use of the machine.
On the turret (or on the ground) you can find the emergency controls to lower or stop the machine in emergency situations,
a key-selector to select the control panel and to start the machine.
1 6 Drive power
The machines can be powered by:
An electric-hydraulic system composed of rechargeable accumulators and electrical pump (models “E”).
A heat engine (Diesel engine models are identified by the abbreviation “D”; petrol engine models are identified by the
abbreviation “B”).
A dual-powered electric/thermic system (dual-powered Electric/Diesel models are identified by the abbreviation “ED”; dual-
powered Electric/Petrol models are identified by the abbreviation “EB”).
In any case both the hydraulic and the electric systems are equipped with all necessary protections (see electric and hydraulic
circuit diagrams annexed to this manual).
1 7 Machine life, demolition and decommissioning
The machine has been designed to last for 10 years in normal operating environments, if properly used and serviced. Within this
period, the manufacturer must carry out a complete inspection/overhaul.
If disposal of the unit is necessary, comply with current local regulations.
In Italy, the demolition/decommissioning must be notified to the local ASL / USL or ARPA.
The machine consists mainly of metal parts which are easy to be identified (steel for the most parts, and aluminium for the
hydraulic blocks); thus, we can state that the machine can be recycled at 90%.
European standards and those transposed by the member countries relating to respect for the environment
and the disposal of wastes envisage heavy administrative and penal fines in case of infringement
In case of demolition/decommissioning, carefully keep to the provisions of applicable regulations,
especially as regards materials such as hydraulic oil and batteries

Use and Maintenance Manual – A21 J A23 J Series Page 10
1 8 Identification
In order to identify the machine, when spare parts and service are required, always mention the information given in the serial
