1INTRODUCTION
This Use and Maintenance Manualprovidesgeneralinstructionsconcerningthecomplete range ofunitsindicated on the
cover. Thereforethedescription of their components, aswell ascontrol and safetysystems, mayinclude partsnotpresent on
your unit since suppliedon request or notavailable. In orderto keep pace with thetechnical development AIRO-Tigieffe s.r.l.
reservestheright tomodifythe product and/orthe useand maintenancemanual at any time without updating theunits
alreadydelivered.
1.1 Legal aspects
1.1.1 Delivery of the unit
Within EU(European Union) member countries the machine is delivered complete with:
-Use and Maintenance manual in your language;
-CE mark applied on the unit;
-CE conformity declaration.
It is tobe noted that theUse and Maintenance Manual isanintegral partof themachine and acopyof this, together with
copiesof the documents certifying that the periodical checkshave been carried out, mustbe kept on board in itssuitable
container. In the event of a transfer of property the machine must always be provided with its use and maintenance manual.
1.1.2 Declaration of commissioning, periodical checks and transfers of ownership
The legalobligations of theowner of the machine varyaccordingto the country of commissioning. Itis therefore
recommendedto inquiry aboutthe procedures in forcein your country from the boardsresponsiblefor industrialsafety.This
manualcontains a final section called "Check register" for abetter filing of documents andrecording of any modifications.
1.1.2.1 Declaration of commissioning
In ITALY the owner of the Aerial Platform must notify theuseof the unit to the localcompetent ISPESL (NationalInstitute for
the prevention of accidentsat the workplace). To declare the commissioningof the unit in Italy, send the formthat issupplied
together with other documents upon machine delivery, by registered letter with advice of receipt.
ISPESL will assign aSerial Number and depending on theirstaff availability will issue a"Check booklet"indicatingonlythe
detectable data of the machinealreadyin use or inferable from the relative User Manual. Afterwards ISPESL sends acopy of
the same bookletto theterritorial inspectionboards(ASL/USL or ARPA) which carryout the periodical mandatory checks
(every year).
1.1.2.2 Periodical checks
The annual checks are compulsory andmust becarriedout also when the "Check booklet"is not available. In Italy the owner
of the Aerial Platformmust apply foraperiodicalcheckby sendingaregistered letter tothelocal competent inspection board
(ASL/USL or ARPA) at least twenty days before theexpiry of the year from the purchase date or the lastperiodical 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 askthe inspection board, competent for the newterritory where the machine istobe
used, forthe annual check.

Use and maintenance manual Self-propelledaerial platforms Page 6
1.1.2.3 Transfers of Ownership
In case of transferofownership(inItaly) thenewownerof theAerialPlatformmust notifythe ownershipofthe unittothelocal
competent inspectionboard (ASL/USL or ARPA) by enclosing a copy of:
-Conformity declaration issuedby the manufacturer;
-Declaration of commissioning carried out bythe first owner.
1.2 Intended use
The machinedescribed in thisuseand maintenance manual is aself-propelled aerialplatform intendedfor lifting personsand
materials (equipment and building 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 remainingloadis represented by the materialbeing worked.
In any case NEVERexceed the maximum capacity allowed as indicated in paragraph "Technical features”. Persons, tools and
building materials can be loaded on the platformonlyfrom the access position (platformlowered). It is absolutely forbidden to
load persons, tools and building materials on the platform when it is not in access position.
All loads mustbepositionedinside the basket. Donot liftloads(even if complyingwith the maximumcapacityallowed)
hangingfrom the platform or lifting structure.
Do not carry large-sized panels since they increase theresistance towind force thus causing the machine to overturn.
While de-placing theunit withlifted platformdo not load horizontalloads ontothe platform(the operators onboard must not
pull ropes, wires, etc.).
Aload controlsysteminterrupts theoperation ofthe unit ifthe load onthe platformexceedsby 25%theratedload (see
chapter "General use instructions”).
The unit cannotbeused in areas whereroadvehiclesoperate. Always surround the working area bymeansofsuitable signs
when the unit is used in publicareas.
Do not use the machine to towtrucks or other vehicles.
1.3 Description of the unit
The machine described in this use andmaintenance manualis a self-propelled aerial platform equipped with:
-motorized chassis equipped with wheels and outriggers;
-vertical scissorliftstructureoperated by one ormorehydrauliccylinders (the numberofcylindersvariesaccording to
machine model);
-operator platformwithmanualroll-out deckextension (the max. capacityvariesaccordingto the model-see chapter
"Technical features").
The chassisis motorised to allowthe machine to move (see "Generaluse instructions"). On 2-drivingwheel modelsthe
chassisisequippedwithtworear drivingwheelsand twofront idle steering wheels.On4-drivingwheelmodelsthe chassisis
equippedwith tworear driving wheels and twofront driving and steering wheels. Alldriving wheelsare equippedwith
hydraulic parking brakes,positive logic type(when drivecontrols are released brakes areautomatically activated). The unit is
also equipped withlevelling jacks to operate oninclined grounds (but sufficiently firm). Inany case the unit is enoughsteady
to operateon horizontalandsufficiently firm groundsand the platformcanbe liftedwith the chassisresting onthefour
puncture-proof tireswithout usingthe levelling jacks. Thesemust beused whenoperating onunevenbutsufficiently firm
grounds. The levelling jacks are controlled fromthe platform control post, wheremachine levelling andoperationsin progress
can bechecked bymeansofaspirit level. Theunit isalsoequippedwithaninclinometer,adevice that inhibits lifting inthe
event that theplatform isliftedat aheight ofabout3meters from the ground(the stabilitylimits of each model are indicated in
paragraph "Technical Features").
The hydraulic cylinders which move the articulated structure and the levelling jacks are provided with solenoid valves or safety
valvesdirectly flanged onthesame.Thisenablestheunittobe held inposition alsoin theeventof anaccidentalbreaking of
the supply pipe.
The platform is equipped withguard-railsand toe-boardsof aprescribedheight (theheightof theguard-railsis≥1100mm;
the height of the toe-boards is ≥150 mm).

Use and maintenance manual Self-propelledaerial platforms Page 7
1.4 Control stations
The machine is equipped with two controlstations:
-at platform for normaluse of the unit;
-on-chassis(or ground) for emergencycontrolsto lower or stop the unit in emergencysituations. The on-ground control
post is also equipped with a key-selector to select the control postand to start the unit.
1.5 Power supply
The machines can be powered by:
-an electric-hydraulicsystemcomposed of rechargeableaccumulators and electric pump (models “-E”);
-aheat engine (Dieselengine modelsare identified by theabbreviation “-D”; petrolenginemodels are identifiedby the
abbreviation“-B”);
-abi-fuelelectric/thermic system (bi-fuel Electric/Dieselmodelsare identified by the abbreviation “E/D”; bi-fuel
Electric/Petrol models areidentified by theabbreviation “E/B”).
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).
Do not use the machine for purposes different from those it was intended for.
If disposal of the unit is necessary, comply withcurrent local regulations.

Use and maintenance manual Self-propelledaerial platforms Page 8
1.6 Identification
In order to identify the machine, when spare partsand service are required, alwaysmention the information given in theserial
number plate. Should thisplate(as well as the various stickers applied on theunit) be lostor illegible, itis to be replacedas
soon as possible. In order to identify the machine when no plate is available the serial number is also stamped on the chassis.
To locatethe plate and the stamp of the serialnumber, see the following picture. Themaindata of the machine to whichthis
book refers are indicated in the following boxes:
