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.

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 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.

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 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. The qualified private institutes acquire the qualification of responsible for the public service and

refer directly to the public structure that controls this 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. Such

document shall form an integral part of the machine documentation.

Use and Maintenance Manual –A12 A13 Series

Page 8

1.1.2.2. Further periodical 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 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 ARPA 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 mobile elevating work 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 cage; do not lift loads (even if complying with the maximum capacity allowed)

hanging from the platform or from the 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 –A12 A13 Series

Page 9

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 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

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 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 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 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.

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 motorised to allow the machine to move even with lifted platform (see “Use instructions”); the two rear

wheels are drive and two front wheels are steering. The drive 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° 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, consisting of a “simple parallelogram” for lifting (boom and tie rod);

▪the second, consisting of a telescopic extension of the primary boom

▪the third, consisting of the terminal boom named “Jib” (for A13 J only).

Such lifting structures are driven by double-acting hydraulic cylinders:

▪one cylinder for the “parallelogram” extension.

▪one cylinder for the boom extension;

▪one cylinder for the extension/retraction of the telescopic boom.

▪one cylinder for the “jib” extension (A13 J only).

The hydraulic cylinders which move the articulated structure (except for the boom tilt 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.

Use and Maintenance Manual –A12 A13 Series

Page 10

The platform, hinged to the end of the primary boom or of the “jib”, is equipped with guard-rails and toe-boards of a

prescribed height (the height of the guard-rails is 1100 mm; the height of the toe-boards is 150 mm). As an option, the

platform can be rotated by a total of 140° (70° to the right and 70° to the left) by means of a rotary actuator, also provided

with an over-center valve.

The platform levelling is automatic and is ensured by 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).

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. Power supply

The machines can be powered by:

▪An electric-hydraulic system composed of rechargeable accumulators and electric pump.

▪electric/thermic dual-powered system (electro/diesel dual-powered models are identified by the abbreviation “ED”).

In any case both the hydraulic and the electric systems are equipped with all necessary protections (see wiring and

hydraulic circuit diagrams attached 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.
