1 Description and
purpose
1.1 Machine definition
The machine is called S32 and it is a mobile
elevating work platform (MEWP):
•machine/device intended for moving persons,
tools and material to working positions, consisting
of at least a work platform with controls, an
extending structure and a chassis (ANSI/SAIA
92.20 par. 3);
•mobile machine intended to move persons to
working positions, where they are carrying out
work from the work platform, with the intention
that persons are getting on and off the MEWP
only at access positions at ground level or on the
chassis and which consists as a minimum of a
work platform with controls, an extending
structure and a chassis (EN 280 par. 3.1).
It is forbidden to use the MEWP with
methods and/or conditions other than those
specified and approved by the
manufacturer.
1.2 Machine purpose
The MEWP S32 is a machine which enables the
operators to reach the workplace when this is high
positioned.
The machine has been designed for an essentially
vertical use. It must be travelled only when it is totally
folded in the transport position.
➔The use of the machine is allowed only to
professional staff, properly trained and
specialized.
1.3 CE certification
C.M.C. s.r.l. states under its own responsibility that S32
was designed and produced in compliance with
national and European standards, and that the
machine is identical to the model submitted to control
and test for the “CE certification” by the Notified
Institute nr. 1878 - VERICERT s.r.l. - via L. Masotti, 5
- 48124 Fornace Zarattini (RA) - Italy.

MAN.218 Rev.12 ENG - Use and maintenance manual S32 page 7of 137
A copy of the CE Certificate is attached to the manual.
1.4 TÜV certification
C.M.C. s.r.l. states under its own responsibility that S32
was designed and produced in compliance with US
standards ANSI/SAIA A92.20:2020 and that the
machine is identical to the model submitted to control
and test for the “TÜV certification” by TÜV SÜD
America Inc.
TÜV SUD America Inc. is an OSHA recognized NRTL
and a Standards Council of Canada accredited
certification body.
1.5 Classification
The mobile elevating work platform (MEWP) S32
belongs to group B: the vertical projection of the area
center of the MEWP in different platform configurations
specified by the manufacturer can be outside the
1
Loading cycle: a cycle starts from the access position,
continues performing the work and finishes returning to the
access position.
tipping lines (EN 280 par. 1.4 - ANSI/SAIA A92.20 par.
3).
As for the displacement, it belongs to type 1: travelling
is only allowed with the MEWP in its transport
configuration or in the stowed position (EN 280 par. 1.4
- ANSI/SAIA A92.20 par. 3).
1.6 Loading cycles
The machine is expected to last for 40.000 loading
cycles
1
(i.e. 10 years, for 40 weeks per year, for 20
hours per week, for 5 loading cycles per hour).
Within this term of time, the machine must undergo
at least 2 (two) deep checks (structural, mechanical,
electric, elements, etc.), in case of particularly heavy
uses (frequent use at the performance limit,
particularly unfavorable environmental conditions such
as steel plants, paper mills and so on) it is better to
increase checks. Anyway, it is a good rule to have
the state of the machine checked by the
manufacturer factory or by an authorized
workshop, at least every 1500 - 2000 hours of work
or once per year.

1.7 Identification plate
On the turret, there is a plate with (engraved) all the
MEWP identification data:

MAN.218 Rev.12 ENG - Use and maintenance manual S32 page 15 of 137
2.3.1 Frame
The frame 1 (Picture 3) is a structure in quality steel, able
to equally divide the MEWP’s equipments weight. The
frame has 4 oil-pressure jack beams for stabilization [2
front stabilizer cylinders 2(Picture 3), 2 rear stabilizer
cylinders 3(Picture 3)]. The basis for the bearing 4
(Picture 3) is placed on the frame. It enables the
swinging of the equipment through the turn-table.
2.3.2 Turret
The turret 5(Picture 3), in quality steel, is secured to the
bushing (bearing). A hydraulic engine, with brake
normally closed, constrained to the turret, allows the
rotation of the overstructure.
2.3.3 First telescopic boom group
The first telescopic boom group 6(Picture 3) is
composed by three elements: a fixed boom and two
extendable booms.
The extension (or withdrawal) of the telescopic boom is
given by operating the “telescopic boom extension
cylinder”.
The movement of the boom (lifting and lowering) is given
by the lifting hydraulic cylinder. Such cylinder is secured
to the turret (cylinder side) and to the fixed boom (piston
side) and is supplied with safety valves.
2.3.4 Second telescopic boom group
The second telescopic boom group 8(Picture 3) is
hinged to the first telescopic boom by a rod 7(Picture 3).
The telescopic boom is composed by two elements: one
fixed boom hinged to the rod and one extendable boom.
The extension (or withdrawal) of the telescopic boom is
given by operating the “telescopic boom extension
cylinder”.
The lifting (or lowering) of the telescopic boom is given
by operating the “lifting cylinder of second telescopic
boom group”.

MAN.218 Rev.12 ENG - Use and maintenance manual S32 page 16 of 137
2.3.5 Jib
At the end of the second telescopic boom is hinged a
boom named Jib 10 (Picture 3). The lifting or descent of
the Jib is done by operating the “Jib lifting cylinder”.
2.3.6 Basket
The aluminum tubulars basket 11 (Picture 3) has a
lateral opening to allow the entrance of the operators.
The lateral opening is automatically shuttered and built
to avoid accidental openings. The basket has a guardrail
1,1 m high from the basket floor, an intermediate
guardrail and a foot protecting band along all sides of the
platform. The floor is in antiskid and auto-draining
aluminum. The basket is connected to a support 9
(Picture 3) through which it is coupled with the jib.
Moreover the support 9 is characterized by anchorages
for safety belts.

3 Command stations
3.1 Machine switching on/off
station
Picture 4: engine on/off station.
By engine switching on/off station (Picture 4), allocated
on the right side of the frame, there are:
•the IK ignition key: through it, it is possible to turn
on the electric system and start the endothermic
engine;
•the green light 5indicating system power supply: it
is on when the IK ignition key is in position 1;
•the red light 4which signals low pressure to the
engine oil;
•the red light 3which monitors coolant level;
•the orange light 2indicating the spark plugs
working;
•the red light 1which signals an alternator failure;
•the emergency bypass BP under the yellow cap
(see par.4.6.2);
•the activation lever of remote connection under the
red cap 6(see par.8.16.1);
•the hour counter 7;
•the 24 V socket 8;
•the red activation button of electropump* DS.
3.1.1 Ignition of the endothermic engine
In order to start the endothermic engine, turn the IK
ignition key all the way to the right up to the symbol .
Before starting the engine, especially if the MEWP is
used in workplaces with low atmospheric temperatures,

it is advisable to heat the spark plugs of the machine
engine while keeping the IK key on the symbol for a
few seconds: this will cause the corresponding orange
light 2(Picture 4) to turn on.
The ignition of the endothermic engine can also be
carried out with the radio control or the console in the
basket.
Using the radio control:
•turn the key to the right;
•connect the radio control (link procedure in par.
3.2.2),
•move the lever in the Picture 5 upwards, present on
the left side of the radio control under the joystick
J1 (Picture 14).
Otherwise, using the console (fixed) in the basket:
•turn the key to the right;
•press the endothermic engine start button 9
(Picture 11)
•the green light 5(Picture 10) will light up on the
console, to signal the correct power supply of the
machine.
Picture 5: power on/off lever on the radio control.
To switch off the endothermic engine, you can
alternatively:
•turn the ignition key all the way to the left;
•lift the lever in Picture 5, if the radio control has
been used;
•press the endothermic engine start/stop button 9
again (Picture 11), if you are at the control station
in the basket;
•press, in emergency situations, one of the
emergency buttons on the machine (par. 4.6.1).
3.1.2 Switching on/off the electric motor
(*optional)
If you choose to use the electric motor*:
•connect the 110/120/230/380 V socket (Picture 6)
on the machine to the nearest electrical source;
