ORIGINAL INSTRUCTIONS
1) IDENTIFICATION OF THE MACHINE
You can identify the model of the machine from the CE plate placed on it (see picture on page 2).
Note: The technical data printed on the plate must be always specified whenever you contact CMC
S.r.l. for information, spare parts requests or any other question you might need to clear up.
2) MANUFACTURER
The machine described in this manual is produced and commercialised by:
CMC srl
Via Padre P. Meroni, 20 – 22031 Albavilla (Co) Italy

3) GENERAL DESCRIPTION
Hand push scarifier to remove road line, equipped with: 6 HP (3600 RPM) GASOLINE ENGINE
(for CM300 machine) or 6,2 HP (3600 RPM) DIESEL ENGINE (for CM300D machine), air cool-
ing, oil bath filter, self-winding pull start. Through pulleys and belts, the engine drives a drum with
four axles each carrying cutters. The engine gives to cutters a rotary movement and, thanks to clear-
ance between axles and cutter hole, a beating movement. This double movement (rotary-beating)
allows to get a perfect scraping also for floors not perfectly flat.
Machine is endowed of a millimeter regulator to adjust the height of cutters from the ground and of
a drum lifting device to stop temporarily the scraping activity.
Maximum scraping width is 20 cm. Handlebar height is adjustable.
3 kinds of cutters are available: hardened cutters with tungsten carbide pins (model F300V), suita-
ble for removing cold paints; cutters with tungsten carbide plates (model F300VD) suitable for re-
moving cold plastic and thermo plastic; hardened cutters for “delicate” removal from concrete sur-
faces (model F300C).
Scraping speed, depending on material to remove, can be ranged from 20 mq/h to 40 mq/h.
Working position of operator is illustrated in PIC.6 N.3.

4) INTENDED USE OF THE MACHINE AND ABNORMAL USES
This machine is designed in order to comply the general rules provided by Machinery Directive
2006/42/EC, 1
st
Annex. According to section 1.1.2 (c) of 1
st
Annex we specify that:
Machine has been built to be used just within a working-place and it is classified as a working ma-
chine. CMC S.r.l. declines all responsibilities for any different use.
Scarifier is thought, designed and built to remove the horizontal marking (paint or plastic) from
smooth surfaces (asphalt, cement, etc.).
Scarifier can’t run freely on the road, must be within the working yard. It isn’t designed for removal of
road paving (asphalt or other) or of building floor (concrete surface or other).
Scarifier musn’t be used for something different from what described in this manual and its en-
clousers.
Uses different from the ones indicated in this handbook cause the immediate loss of warranty and
decline any responsibility of the manufacturer for damages to the machine, third person and things.
Attention
At the end of its working life, the machine and its components must be disposed in compliance
with the regulations in force in the Country of installation
5) RESIDUAL RISKS
Remain risks of airborne noise emissions and inhalation of fumes.
Operator is informed about risks of noise and of inhalations of smokes by proper safety symbols.
Symbols are stuck on belt carter, to be well visible from working position.
Enclosed to this handbook there is a sketch of noise and vibrations in order to evaluate which pro-
tection devices to adopt.

ORIGINAL INSTRUCTIONS
6) SET UP
If machine arrives to user by a forwarder, it is packed in carton pallets. Once at user’s, the parcels
must be handled with care and must be moved by proper lifting equipment depending on their
weight and size.
Attention
The manufacturer declines all responsibilities for damages to things or people caused by every sort
of careless behaviour or non-observance of the safety rules in force, concerning the lifting and the
handling of items within the user’s seat
Here following we suggest the different solutions of lifting equipment, which are normally used,
underlining that they will have to be chosen on the base of the parcel weight and size:
Overhead travelling crane; Self-propelled forklift; Manual forklift.
Machine weight is written in CE plate fac-simile on page 2.
To bring down the machine from the pallet, use a wedge of appropriate size for the axle base of ma-
chine wheels. Then push machine to the ground.
Alternatively lift machine by hand: see instructions in chapter 14) TRANSPORTING OF THE MA-
CHINE BY TRUCK.

11) SET AT WORK
Adjustament of handlebars height:
-Cut the straps that hold the wire of safety device
(PIC.1)
-Unscrew the screw for regulation of handlebar height
through spanner 17 (PIC.2 N.1)
-Adjust the height of handlebars
-Tighten strongly the screw of regulation of handlebar
height through spanner 17 (PIC.2 N.1)
-Reposition the safety device wire as in picture (PIC.1)
and fix it through straps
To avoid to start scraping with wrong cutter height, before starting the engine make sure that cutters
don’t touch the ground. Follow below instructions:
1. Lift lever (PIC.3 N.3) for unlocking the lifting device and push down the knob (PIC.3 N.2) for
lowering the cutters unit in working position (PIC.4 N.2)
2. Check that cutters do not touch the ground. If necessary, push forward the scarifier to make sure
3. If cutters touch the ground, turn anticlockwise the grip (PIC.3 N.1) till they are up from the
ground
Pay Attention!
The handlebar has a limit-switch
screw to avoid that the handle-
bar can accidentally slip off.
This screw (PIC.2 N.2) must
never be unscrewed. Before
starting work always check that
screw is well tightened.
