STARTING UP
ATTACHMENT TO THE TRACTOR
It is advisable to read carefully this Operator’s Manual as well as the instruction manuals of the
tractor and the PTO shaft manufacturers.
All SICMA chippers have been manufactured to be attached to any tractor provided with hydraulic
lift and universal three-point hitch.
Before attaching the equipment to the tractor, set both on a flat and smooth ground and make sure
that nobody is standing between them.
•Approach slowly
the chipper with
the arms of the lift
and connect first
the lower arms
and then attach
the upper third
point hitch. The
chipper is
equipped with
attachment pins of
1st category (ø22).
•Make sure you fix
the pins with the
corresponding
safety pins.
•Lock the arms of
the lift with proper
chains or anti-
shaking
tensioners.
After havin accomplished the above-mentioned activities it
is always advisable to check that all bolts and nuts of your
chipper are ti htened stron ly (ref. bolts and nuts ti htenin
table).
Pay attention to the tractor’s front wheels rip when the
equipment is set up and lifted from the round; if the wheels
appear to be too li htened, ballast the tractor front part.

DRIVELINE ATTACHMENT
Before assembling the cardan shaft, it is very important to check out that its number of revolutions
and direction of rotation match those of the tractor. Also, read carefully the instruction manuals of
the cardan shaft and the tractor’s manufacturers. Before starting work, check the presence of the
safety guards on the power takeoffs of the machine, of the cardan shaft and of the tractor. Check in
particular that the safety guards cover the cardan shaft throughout its extension.
When at their maximum extension, the safety uards’ plastic
hoses shall overlap of at least 1/3 of their len th (LT). When
in their maximum closin position, the minimum clearance
allowed shall be of 1-2 cm (picture 1).
Fi . 1
Check out that the PTO shaft minimum and maximum
length are the ones required by the machine-tractor
coupling.
Should problems arise, contact a
skilled repair shop or
the cardan retailer.
After installation, secure safety
guards both to the tractor and the machine using the
special chains and make sure that they pivot freely.
If
the PTO shaft is equipped with other safety devices,
such as a pair
limiter or freewheels, be sure to install
them on the working machine side. As for the PTO use
and maintenance refer to the relevant booklet.
These operations shall be made only on workin round and
only after havin stopped the en ine, disen a ed the power
takeoff and pulled the parkin brake. If necessary, lift the
machine from the round but, in order to avoid risks for
people, place it on supports thus preventin any injuries that
mi ht be caused by its sudden fall.
CHECKS PRIOR TO STARTING UP
Before starting the chipper check the following:
-The machine is properly connected.
-It is firmly rested on the ground.
-The chipper is parallel to the ground in order to avoid major stress on the PTO.
-The knives are sharpened.
-The blower discharge tube is correctly mounted and oriented.
STARTING UP OF THE CHIPPER
When all setting up operations are completed, your machine is ready to be used.
At this point it is possible to engage power take off and work the machine at full capacity.
Use the power take off only at 540 rpm.

MATERIAL FEEDING SYSTEM AND TRITURATION
Before starting triturating
make sure the unit has
reached regular speed.
•After having correctly
oriented the blower
discharge tube, open the
hopper cover.
•Accurately select the
wooden material to be
triturated and do not
exceed the maximum
cutting diameter of
100mm.
•Small branches can be
kept together and put in
simultaneously with their
roots turned towards the
entrance.
•Absolutely avoid pushing
the branches down the
hopper slide using the
hands. Use other pieces of
wood and if necessary,
use proper pusher device.
Before puttin the parts to be chipped into the hopper,
remove parts different from wood so that knives are not
dama ed.
ROAD TRANSPORT
While transporting the machine it is very important to follow the road traffic code of the country
where you circulate.
