The purpose of this manual is to provide the user with full information on the use,
the safety and the maintenance of the MULTITEL platform, and to facilitate its use
so as to obtain the top performance for which it was designed and built.
For reasons of safety, all the personnel entrusted with operating the machine,
supervising the works for which it is used and servicing it should study this manual
carefully.
This manual should be considered an integral part of the machine, and should
therefore always be kept together with it.
Technology evolves rapidly and we are constantly at work with the aim of improv-
ing our products, to make them more functional and safer. A yearly inspection of
your machine by one of our branch offices is therefore recommended, not only in
order to carry out a thorough check on the existing devices but also to give you
advice on the installation of newer and more efficient systems so that you can
improve the performance and safety of the model you use.
IMPORTANT NOTICE: ALL OPERATORS SHOULD READ AND UN-
DERSTAND THE INSTRUCTIONS CONTAINED IN THIS MANUAL
BEFORE USING THE PLATFORM.

FOREWORD
Thank you for choosing one of our platforms for your work.
Our first commitment in manufacturing the products is to ensure safety.
We hope that you will pay the same attention while using the platform so as to ensure your own
safety and that of other operators.
During daily use of the platform you should comply with the following rules:
1) apply all the appropriate national and local laws and regulations concerning equipment for
lifting persons:
2) read, understand and apply the instructions contained in this manual;
3) use the platform and the working tools with common sense;
4) the platform may only be used by authorised personnel who have been trained for this job.
If there is anything in this manual which is not clear to you, do not hesitate to contact our sales or
servicing organisation through the nearest representative.
PAGLIERO’s MULTITEL range platforms are made entirely of light alloys and high-quality high-
tensile steels.
This means that they can be mounted on vehicles of the lighter type, with considerable savings on
capital expenditure and greater manoeuvrability even in urban environments, high displacement
speeds and an ideal distribution of the loads on the axles for easy and safe driving. The movements
are controlled entirely by the oil-hydraulic system, by means of jacks with thickly coated chromium-
plated steel stems and ground cylinders. Rotation through 360° is possible.
All the pivots rotate on bearings made of anti-friction metal.

WORK IN THE VICINITY OF LIVE ELECTRICAL LINES
1) Should the platform, boom or other parts of the structure come into contact with live wires
which have not been insulated, serious bodily injury may be caused.
2) If it is necessary to work in the vicinity of live wires, make sure that the safety distances are
complied with and follow the specific procedures agreed to with the parties responsible for
safety.
3) Before starting to work near electricity lines, make sure that whoever is in charge of the lines
has been notified and that same will not be unexpectedly energised.
4) In any case, put barriers or shields into place in order to avoid physical contact and electric
arcs.
5) Possible swaying of the platform and of overhead lines must also be taken into account.
INSULATION
Ifspecificallyrequested, some platformscanbe built withinsulationarrangements inserted between
the cage and the boom and between the boom and the turret, or both.
The resistance values at the rated insulation voltage will be tested at the time of delivery. These
values should be checked on a monthly basis to make sure that they do not drop off in time.
Thepresenceof dust, accumulateddirtand an excessofmoisture in theairmayaffect theinsulation
negatively even to a drastic extent.
Keep the insulating area clean by washing it with water. Avoid using acids, solvents and sprays of
pressurisedoroverheatedwater. Allowtodrybeforeusingthemachineagain.
In the event of servicing or replacement of oil pipes, pay attention to the fact that some pipes may
be of the insulated type without metal braids.
Insulation of the platform does not, in any case, provide protection against electric shocks due to
contact of the operator with two leads or between a lead and earth.
In the stowed position, the insulation no longer has any effect.
Use of a fibreglass-reinforced plastic cage is not sufficient to indicate that the machine is insulated.
Checkthisrequisitecarefullybefore working with energised materials.

DESCRIPTION OF THE PLATFORM
The platform consists basically of the following :
1) Counter-frame for securing the platform to the main frame members of the chassis of the
carrying vehicle ( item 1).
2) Rotation system consisting of an internally toothed large-diameter ball-circulation slew ring,
with automatic brake operation and an epicyclic reduction gear (item 2).
3) Turret or basic unit inside which the control and activation valves of the oil-hydraulic system
arearranged(item 3).
4) Hydrauliccylinderforturning theboom,ofthe double-actingtype,completewith hydraulically
controlled locking valve (item 4).
5) Telescopicboomwith oneormore simultaneouslyextractedhydraulically operatedtelescopic
sections (item 5) controlled by a double-acting hydraulic jack, complete with a balanced
hydraulicallyoperatedvalve(item6).
6) Workingcage(item7), madeofaluminiumsections or fibreglass-reinforcedplastic,complete
withhydrauliccircuitforautomaticlevelling.On request,thecagecanbe mountedonbushings
made of a high-insulation material, in order to insulate the cage electrically from the booms.
7) Four hydraulically operated outriggers consisting of four double-acting cylinders, which are
operatedseparately,andwhich can be usedtoplacethemachine on a perfectlevel(item8).
8) Control devices, consisting of :
a) a control panel located on the right side of the vehicle, containing the controls for the
outriggers(item9);
b) a control panel on the working cage, containing the boom controls, which are of the
proportionaltypewith thepossibilityof changingspeedat thediscretionof theoperator,
in addition to the various other controls such as those for starting and stopping the
engine of the vehicle, starting the motor-driven pump, etc. (item 10);
c) an emergency control panel, for operation from the ground, including all the functions
of the bottom (item 11).
These controls consist of levers with automatic return to the neutral position. Suitable
safety devices prevent incorrect manoeuvres, and in particular it is impossible to lift
the bottoms out of the stowed position if the outriggers are not resting firmly on the
ground. Similarly, it is not possible to lift the outriggers from the ground if the bottom
is not in the stowed position.
d) Level indicator for finding the horizontal position of the platform (item 12).

knowledgeof thesedevices isessential fortheoperator,anditisabsolutelynecessaryfor himtobe
familiar with the controls and the relevant symbols before starting to use the machine.
STABILISING OF THE VEHICLE
To work in safety, perfect stabilising of the vehicle is essential..

While operating the outriggers check visually that no-one can be injured as the jacks are being
lowered to the ground. If it is not possible to see all the outriggers from the control station , fence off
the area to prevent access.
Thecontrolsfortheoutriggersare ontherightsideofthevehicle(seeitem9)consistingoffourcontrol
levers, each of which operates a single outrigger. By pushing down the lever the corrisponding
outrigger should be lowered, by pulling up the lever the corrisponding outrigger should be raised .
When the vehicle is lifted off the ground, a green "enabled" indicator lamp -F- turns on allowing all
the boom functions.This lamp is located on the electric box near the outrigger control box.
Use the level indicator to make sure that the vehicle is on a perfect level. If it is not, use the control
levers to lower the appropriate one.
If not otherwise indicated, the max. slope allowed is 1°.
Once this operation has been completed, check that the green "Enabled" lamp is on.
To achieve correct stabilisation, the wheels of the vehicle must have been lifted off the ground.
Formachinesfittedwith box-typeobliqueoutriggers,it iscompulsorytoextendthem untilthegreen

OPERATING PROCEDURE
Theoperatorclimbdirectlyintothecageorhemaylowerittothegroundusingtheemergencycontrols
onthegroundcontrol box.
On the ground control unit there is a two-position selector switch (G), used to activate the main
controls in the cage or the emergency controls from the ground.
Activating one of these functions automatically excludes the other.
Oncethecage-mountedcontrolshavebeenactivated,thekeymustberemovedfromselectorswitch
(G)andinsertedintoselectorswitch(T)locatedinthecage,turningittoposition1toenablethiscontrol
station (see photograph).
The controls in the cage include n. 3 proportional levers (see picture) :
1st lever - M - :When this control lever is pushed the central jack is raised, and when it is pulled it
is lowered.
2nd lever - N - : Whenthiscontrolispushedthetelescopicboom is extended and when it is pulled
it is retracted.
3rd lever - O - :Rotation of the turret.
On top of that there is a little lever -P- for the manual correction of the cage levelling.
The controls from the ground or the base station include the following (see picture):
1st lever - A - : When this control is pushed the central jack is raised, and when it is pulled it is
lowered.
2nd lever - B - : Whenthiscontrolispushedthetelescopicboomisextended,andwhenitispulled
it is retracted.
3rd lever - C - :Rotation of the turret.
4th lever - R - : Proportional increase of the speed of the movement which has been selected.
Both on the ground and in the cage there are mechanically locked red emergency push-buttons - E
- and - U - activation of which locks all the movements and also, when envisaged, the engine of the
vehicle.

The movements must be started and terminated gradually, without sudden stops and starts.
Jerkyoperationswouldcausetriggeringofthedeviceforlimitingtheworkingoutreachandcouldlead
to vibrations of the valves. In this case the movement must be stopped and then resumed more
gradually.
OPERATIONS FOR STARTING AND FOR STOWING THE BOOM
In order to avoid damaging the mechanical stop of the boom in the stowed position and its support,
it is necessary to proceed as follows:
- with the machine in the stowed position, before raising the boom use the control to select
telescopicretractionandthenselectthemovementforraisingtheboomuntilitmovesoutwards
from its support.
Never, under any circumstances, perform rotating or extraction movements while the boom
is in the stowed position on its suppport.
- to place the machine in the stowed position, after lowering the boom to bring it close to the
support, rotate it until it is perfectly centred and the green reference marks on the slew ring
coincidewith oneanother.Thenretractthetelescopicboomcompletelyandloweritgentlyinto
its support.
Do not exert any force against the uprights at the sides of the support.
ELECTRIC MOTOR
If requested by the customer, it is possible to install an electric motor for operating the hydraulic
pump feeding the oil-hydraulic system.
If the platform is to be used with an electric motor, it is also necessary to connect the power take-off
of the vehicle and switch on the ignition key of the engine of the vehicle.
The engine is protected by means of a magnetic thermal switch.
The engine must be fed by means of a cable with a minimum cross-section of 4 mm²with an
earthing lead. Avoid using excessively long cables.
Make sure that the socket has fuses and differential switches for protection purposes.
To make sure that the charge of the battery of the vehicle is maintained while the platform is being
used with the electric motor, a battery charger is installed. This is activated when the engine is
started.
Adjust the charging current so that 10 % of the capacity of the battery is not exceeded.
DO NOT EXCLUDE THE PROTECTION DEVICES OF THE ENGINE AND BATTERY CHARGER
WHEN THE EXTERNAL 220 V POWER SUPPLY IS ON.
DONOTSWITCHONTHEPUMPOFTHEVEHICLE AND THAT OF THE ELECTRIC MOTOR AT
THE SAME TIME.

14
HORIZONTAL LEVELLING OF THE CAGE
Thecageisfittedwith a hydraulic circuit forkeepingithorizontal.If you need to adjustthehorizontal
levelling, use lever - P - of the cage controls (see photograph).
EMERGENCY LOCKING
Each control station (in the cage and on the ground) has a locking push-button - E - U - easily
recognised by its red colour and mushroom shape (see photograph).
If the platform does not work properly or if all the controls are out of service, press this push button
immediately. If the machine has a remote starting and stopping device for the main engine, the
locking push-button will also cause the engine to stop.
To unlock the push-button, naturally after eliminating the cause which led to its being pressed, turn
the head in the direction of the arrow.
SOUND LEVEL AND VIBRATIONS
1) Themaximumsoundlevelisthesameofthevehicleengineusedfortherunningofthehydraulic-
pumps (Engine of the vehicles - auxiliary engine - electrical motor).
Take off this value from the characteristic supplied from the engine manufacturer.
2) This kind of equipment does not produce important vibrations.

LIMITING DEVICE
Withveryfewexceptions,theboomisfittedwithanautomaticdevicewhichlimitsitsrangeof action,
so as to ensure stability in any operating condition. This device functions automatically, as follows :
- the telescopic boom is made up of several sections and can only be extended to a given
length.Whenitreachesthispointthedownwardmovementsofthemainjackandthemovements

arepossible.
A red lamp on the cage control panel indicates that the locking condition has been reached.
Oncethelamphasturnedon,donotaddanymoreloadstothecageandproceedcarefullysince
the performance limits of the platforms have been reached.
The maximum outreach varies depending on the load in the cage, that is to say it corresponds
to the measurements shown in the table for the rated load on the cage, and increases
proportionallyforthelighterloads.
The best performance levels can be reached by making smooth movements.
Viceversa,ifthemovementsarejerky,thepressurepeakswilltriggerthelockingdevicesooner.
CHECK PROPER OPERATION OF THE LIMITING DEVICE ON A MONTHLY BASIS
The check should be carried out as follows:
- place the rated load in the cage;
- give the boom an inclination of 20 ° then extend the telescope;
- the platform should stop when the outreach indicated in test book ("Technical Features of the
accessplatform","AIForAPAVEApprovalCertificate","PrüfbuchfürHebebühnen","ABOMA
Approval Certificate", etc.) is reached;
- activate the central jack lowering control: the boom may not move any lower;
- perform these operations on free ground;
- afterward, with the operator on the cage, check if the red indicator lamp on the cage controls
lights on when the boom reaches the stop (Limiting device indicator lamp - see photograph
page 22);
- definebeforehandthepointwherethe boom should stop, and ifthereisanydoubt,ratherthan
continuingwiththe operationsbringthemachine tothestowedposition andcallin a specialised
technician.
NEVER OPERATE THE MACHINE, UNDER ANY CIRCUMSTANCES, IF THERE IS ANY
DOUBT AS TO OPERATION OF THE LIMITING DEVICE.
This kind of machine is provided of double circuit limiting working on two channels. In case of a
default intheoperationofoneofthetwochannelsthemovementsstop.Pushthe emergencybutton

- ifthebasketcontrolsdonotworkchecktheoperationoftheones atgroundlevel,ifnecessary
use the spare wrench for selection . This wrench is supplied upon delivery of the vehicle and
shall be kept in the cabin.
- if the main pump works correctly, there is no need for using the manual pump
- if the main pump does not work, but the controls work from an electrical standpoint, pump
manually but work from one of the control seats
Intheeventoffaulty operation of the platform,itispossibletolower the cage to thegroundagainby
proceeding as follows :
1) For the models 180 and 220 ALU remove the carter located behind the turret; for the model
160 ALU open the door of the drawer located under the truck body, to reach the hydraulic
components;
2) Turn the hand-wheel of the speed-control valve (2) as far as it will go but without forcing it;
3) Pressthesmall push-buttonsofthesolenoidvalves toobtaintherequiredmovements, keeping
in mind that the valves are arranged as follows, starting from the bottom:
3rd : telescopic boom control solenoid valve;
4th : main cylinder control solenoid valve;
5th : turret rotation solenoid valve;
6th : cage level correction solenoid valve,
To lower the central jack, since this movement is controlled by the circuit of the limiting device it is
necessary to press at the same time the small push-button on the end of the coil of the solenoid

CLEANING THE FILTERS
Topperformance,constantefficiency and alongservicelifeof the hydrauliccomponentsisensured
by taking proper care of the cleaning operations and using the correct quality of oil.
WethereforerecommendthatyoualwaysuseAGIP ARNICA32hydraulicoiloracompatibleequivalent
(ISO - L - HV).
Wemustremind youthatmixingoils whicharenotperfectly compatiblemaycauseserious damages
inside the oil-hydraulic system.
There are two filters, one on the high-pressure delivery line and one on the suction line.
The delivery filter has a visual indicator to show when it is clogged. When the indicator has turned
completelyredthecartridge must bereplaced.Unscrewthe body ofthefilter withawrench, replace
the cartridge, clean the container, lubricate the sealing gasket and then screw tightly back in place
by hand, without using a wrench.
The suction filter should be cleaned once every six months.
If it is of the spin-on type, unscrew the cartridge and replace it.
If it is of the cartridge type, it may be sufficient to wash it with Diesel oil and to blow it clean with
compressed air. If the filters are to be replaced, use cartridges having the same filtering capacity,
since different degrees of filtering can cause serious damages to the pump and to the oil-hydraulic
system.
Check the level of the oil in the tank regularly, using the level indicators engraved on the rod under
thesealingcap (the levelmustbechecked withtheboomsin the stowedposition).The level mustbe

PERIODICAL CHECKS
CHECKS TO BE CARRIED OUT ON STARTING EACH DAY OF WORK
- Make sure that there are no visible leakages from the oil-hydraulic system;
- make sure that there are no torn wires or cables;
- make sure that there are no pins protruding from their seats or with signs of seizure;
- make sure that the parapet of the cage are sound;
- make sure that none of the limit switches are broken or out of place;
- check operation of all controls before lifting the boom completely.

has to absorb the continuous vibrations of the equipment when the carrying vehicle is moved from
one place to another.
Periodical checking of the tightness of the bolts holding the slew ring in place and of the counter-
frame is therefore recommended.
Check the tightness of the bolts of the power takeoff and of the hydraulic pump periodically.
For the tightness values, consult the attached table of tightening torques:

OPERATIONAL CHECK OF THE CONTROLLED CHECK VALVES ON THE
STABILIZERS:
· place the vehicle-mounted platform in the working position, with the stabilisers in place;
· turn off the engine of the vehicle, leaving the main switch of the control panel on;
· move the control lever of the outriggers repeatedly, making sure that none of the stabilisers
move.
OPERATIONAL CHECK OF THE CONTROLLED CHECK VALVES ON THE
BOOM:
· partly raise the platform;
· turn off the engine of the vehicle, leaving the main switch of the control panel on;
· move the control levers of the various movements repeatedly, making sure that the boom
does not move.

LUBRICATION
Lubricateallthepoints where the greasenipplesarelocatedat least once aweek(seetable1 in the
SparePartsManual).
Use AGIP GREASE 30 grease or products of equivalent quality.
Grease the articulated joints, if any, of the cardan propelling shaft of the hydraulic pump once a
week.
CLEANING THE BOOM
The telescopic boom should be cleaned once a month, or more frequently if it is used to work in
particularlydirtyenvironments.Removethe old grease.
Onceeverythreemonths, raise the boomcompletely,removethe rear cover, extendandretractthe
telescope device several times to allow the dirt and any residues which have accumulated inside it
to drop out. This operation is particularly important if the platform has been used to carry out tree-
pruningwork.
