SAFETY
SAFETY IN THE WORKPLACE
Most of the accidents which take place while the operator is using the machine or the equipment or
during their maintenance or repair are caused by a lack of compliance with the basic safety
precautions.
It is necessary, therefore, to become more and more conscious of the potential risks of one’s action
by constantly paying attention to its effects.
If potentially dangerous situations are known, accidents can be prevented!
OPERATOR’S REQUIREMENTS
All operators using the equipment must be competent and meet necessarily the following features:
Physical: good eyesight, coordination and capability of carrying out all functions required for the
machine’s use.
Mental: capability of understanding and applying the established rules and safety precautions.
Users must pay attention and be sensible for their own and other people’s safety
Training: users must have read and studied this manual, its eventual enclosed graphs and schemes
and its identification and danger plates. They must be skilled and trained on any use or maintenance
activities.
WORK CLOTHING
When working and especially when executing repair or maintenance activities, it is necessary to
wear the following clothing and safety accessories:
-Overalls or other comfortable clothing, not too loose to prevent the possibility that parts of
them might be caught in the moving parts.
-Protective gloves for hands.
-Protective glasses or faceplate to protect eyes and face.
-Protective helmet for the head.
-Safety shoes
Wear only personal safety accessories in good condition and
complying with the rules in force.
GENERAL SAFETY RULES
Always consider the features of the area where work is taking place:
-When the equipment is running, it is forbidden to stand within the field of action of the tilling
cutter or of the other accessories of which it is provided with.
Prepare the work:
Before and when working do not drink alcohol, take drugs or any other substances which may alter
your capability of working with machine tools.

Sicma S.p.A.
Miglianico (CH)
page 11
-Be sure to have sufficient fuel, to prevent a forced stopping of the machine, maybe during a
critical movement.
-Do not use the equipment under unsafe conditions. For instance, it is forbidden to execute
makeshift repair activities just to start working; it is forbidden to work at night with an
insufficiently illuminated working area.
When working or during the maintenance activities it is necessary to remember:
-The labels and stickers providing instructions and pointing out the dangers, must not be
removed, hidden or made illegible.
-Do not remove, except in case of maintenance, the safety devices, protective covers or
sumps. When it is necessary to remove them, stop engine, handle with care and reassemble
them properly before restarting the engine and using the equipment.
-It is forbidden to lubricate, clean and adjust the moving parts while they are running.
-During maintenance or adjustment activities on the equipment it is forbidden to use hands
for executing operations for which there are specific tools.
-Do not use tools in bad condition or inappropriately, for instance pliers rather than monkey
spanners, etc.
-Before executing interventions on hydraulic lines under pressure, disconnect their
components and make sure that the line is no longer under pressure and that it does not
contain any hot fluid.
-Check out all pipe fittings and make sure that they are well connected before raising steam to
the hydraulic lines.
-When maintenance or repairs are completed check out that no tools, wiping rags or other
materials are left inside spaces or guides with moving parts.
-While using the equipment it is forbidden to make more than one person give directions and
make signals. The eventual directions and signals relating to the load handling must be given
by a person only.
-Do not unexpectedly call an operator while he is working if not necessary; it is forbidden as
well to frighten who is working and throw objects, even if just for fun.
-Watch out those present, especially the children!
-Make always sure that no people stand within the equipment’s ray of action.
-Do not make people get on the machine.
-When the equipment is not needed, stop the vehicle’s engine, park it on a flat ground with
first speed and parking brake on, with the machine rested on the ground and power takeoff
disengaged.
-Do not make any cleanings, lubrications, repairs or adjustments with running engine and
lifted machine.
-Never use the machine in steep slopes which may jeopardize the equipment’s stability.
SICMA declines all responsibility for a lack of compliance with these instructions.

SETUP
ATTACHMENT TO THE TRACTOR
It is necessary to read up this instruction manual and the manuals of the tractor and cardan shaft
manufacturer.
All SICMA tillers have been manufactured to be attached to any tractor provided with hydraulic
elevator 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.
Move slowly the
tractor towards the
tiller by aligning the
tractor elevator’s arms
to the two tiller
hitches’ lateral
gudgeons; stop
engine and pull
parking brake.
Picture 3 Picture 4 In some SICMA tillers it is
possible to adjust the hitches
position.
On ZLL, CS, ST, SM, SP tillers,
adjustment can be made by
loosening bolt B (picture 3) and
modifying the position of plates
A. Tighten strongly all bolts
after regulation (ref. bolts and
nuts tightening table) .
On SA and SB tillers the hitches
regulation can be made by
moving spacing bushings A
(picture 4)
Once the hitches regulation is done, connect the lower arms by removing the release pins of the
gudgeons placed on plates A,inserting the elevator bars into the arms centre and fastening them
with the relevant release pins, which had been removed in precedence.
Connect, afterwards, the tractor tie rod to the
third upper point by removing the pin located
between the plates, inserting the tie rod itself
and locking it with the pin.
Adjust the third point so that the upper part of the
frame is parallel to the ground.
Lock all connection parts with the special sway
chains or tie rods.
It is always good to make sure that the central
group axis (sump/bevel gear pair) is parallel to
the ground thus reducing the stresses on the
power takeoff and extending the working life of
the equipment.

Sicma S.p.A.
Miglianico (CH)
page 13
After executing the above-mentioned activities it is always
good to check that all bolts and nuts of your tiller are
tightened strongly (ref. bolts and nuts tightening table).
ATTACHMENT TO THE CARDAN SHAFT
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. Moreover, read carefully the instruction manuals
of the cardan shaft and the tractor manufacturers.
Before starting work, check the presence of the safety guards on the power takeoffs of the machine,
the cardan shaft and the tractor. Check in particular that the safety guards cover the cardan shaft
throughout its extension.
When at their maximum extension, the safety guards’ plastic
hoses shall overlap of at least 1/3 of their length (LT). When
in their maximum closing position, the minimum clearance
allowed shall be of 1-2 cm (picture 5).
Picture 5
Check out that the cardan 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 cardan shaft is equipped with other safety devices,
such as a pair limiter or freewheels, be sure to install
them on the machine side. As for the cardan use and
maintenance refer to the relevant booklet.
COVER ADJUSTMENT
The rear cover can be adjusted in height to better compact
the round and make it flat. The adjustment can be made by
releasing chain A (picture 8) from upper hook Band
inserting it back to the needed height.
Picture 8
These operations shall be made only on working ground and
only after having stopped the engine, disengaged the power
takeoff and pulled the parking brake. If necessary, lift the
machine from the ground but, in order to avoid risks for
people, place it on supports thus preventing any injuries that
might be caused by its sudden fall.

Sicma S.p.A.
Miglianico (CH)
page 14
WORKING DEPTH ADJUSTMENT
The machine’s working depth is determined by the position of side skids.
Lifting the skids the work depth increases, lowering them it decreases; it is important to lift or
lower skids equally on both sides.
To adjust the working depth on SA, SB, SF, SD, SM-F, SM-F, SHV-SHF-SHE, CS, ST and SM
tillers, screw out and remove screw A(picture 6) and adjust the height of the skid through holes B.
At the end of these operations tighten screws strongly (ref. bolts and nuts tightening table)
To adjust the working depth on SP and RG tillers, loosen screw nut A (picture 7) and make
regulation rod B slide up to needed height. At the end of these operations tighten screws strongly.
Picture 6 Picture 7
These operations shall be made only on working ground and
only after having stopped the engine, disengaged the power
takeoff and pulled the parking brake. If necessary, lift the
machine from the ground but, in order to avoid risks for
people, place it on supports thus preventing any injuries that
might be caused by its sudden fall.
SPEED GEAR
ST speed gear, SM speed gear, SM-F, SP and RG tillers are provided with speed gear and it is
possible to modify the rotor speed independently from the speed of the tractor power takeoff. Higher
speeds improve the soil working speed but produce a faster wear of rotating parts.
-To change speed on ST speed gear, SP and RG tillers leave cover A(picture 9) from
gearbox and invert gear wheels Band Cinside it; it is possible to obtain two more speeds by
replacing the assembled gears with those put into the cover.
-To change speed on SM speed gear and SM-F tillers just move lever A(picture 10)
following the indications shown on the gearbox (1, 2, 3).
As for the gear’s speed, refer to the stickers put on the machine.
Picture 9 Picture 10

Sicma S.p.A.
Miglianico (CH)
page 15
Do not act on gears before having stopped the engine,
disengaged the power takeoff, pulled the parking brake and
placed the machine on the ground.
CHAIN TENSION
SA, SB, SF chain, ZLL, CS chain,SP chain and HLV-HLF tillers are
equipped with chain drive.
As for SA, SB, ZLL and CS chain models, the chain tension adjustment
takes place during assembly; for eventual further regulations during the
machines’ use please contact SICMA authorized repair shops.
As for SP chain tiller, the chain tension adjustment is made through a
tightener (picture 11). Eventual excessive clearances can be regulated
by loosening lock nut Aand screwing screw Bto its fullest without
forcing (up to the chain maximum tension), then loosening screw Bof
about two turns (thus avoiding excessive chain tension). Keeping screw
Bstandstill, tighten lock nut Astrongly (ref. bolts and nuts tightening
table).
Picture 11
Adjustment of the chain shall be made with standstill
machine after having stopped the engine and disengaged the
power takeoff.
SIDE SHIFT ADJUSTMENT
SA, SB, SF, SD, HLV-HLF, SHV-SHF-SHE and SM-F tillers are provided with side shift.
As for SA and SB models, when a side shift is required loosen nuts A(picture 12) to make the main
frame slide as needed; tighten nuts strongly after regulation (ref. bolts and nuts tightening table).
SF and SD models are not equipped with hydraulic side shift, therefore shift can be made through
the special screw A(picture 13); for adjustment, insert crank Bin trailing tang Cand swing it up to
needed shift.
Picture 12 Picture 13

Sicma S.p.A.
Miglianico (CH)
page 16
HL and SH side shift
HLV-HLF and SHV-SHF-SHE tillers are equipped with automatic hydraulic side shift, useful in case
of workings which require a shift of the machine’s body with respect to the tractor axis. Models HLF,
SHF (orchard version) and SHE (intermediate version), are equipped with a hitch which is shifted
from the tractor axis.
INTER-LINES TILLAGE
To set in action the automatic hydraulic side
shift during inter-lines tillage:
-Release feeler A(picture 14)
-Extract the locking gudgeon B(picture
15)
-Move lever C(picture 16) in position 2
NORMAL TILLAGE
With machine in standard position, insert the
locking gudgeon B(picture 15) and move
lever Cin position 1(picture 16); hook feeler
A(picture 14)
Picture 14
Picture 15 Picture 16
The machine automatic shift is made through
pressure on the feeler. The feeler’s resistance
and its sensibility can be adjusted through
spring G(picture 17) placed behind the
deviating device. It is also possible to adjust
the feeler height through screws Cand D
(picture 18) and its amplitude (ray of action)
through screw E(picture 18).
Moreover, HLV-HLF and SHV-SHF-SHE tillers
are equipped with a lever (F- picture 19) for
the manual setting of hydraulic side shift.

STARTING UP
Now that all setting up operations are completed, your machine is ready to be used; after reaching
the work place we advice to engage power takeoff only after having lifted the machine of a few
centimetres with the tractor elevator. After this, it is possible to start engine, engage power takeoff,
drop the machine down to work position and start using it.
ROAD TRANSPORT
While transporting the machine it is very important to follow the road traffic code of the country
where you circulate.
SET ASIDE
If the tiller will not be used for a long period of time, we advice to:
1Wash the machine accurately and dry it.
2Check out all equipment and replace eventual damaged or worn parts.
3Tighten strongly all bolts and nuts (ref. bolts and nuts tightening table).
Make an accurate greasing and finally protect the whole machine with a tarpaulin and put it in a dry
place.

MAINTENANCE
Maintenance is a fundamental operation to extend life and performances of any agricultural vehicle;
taking care of the machine grants you not only a good work execution, but also a longer life of the
whole equipment and a greater safety on the workplace.
The operating times indicated on this manual have just an informative character and are referred to
normal conditions of use; they can thus undergo variations according to the type of service, to the
more or less dusty environment, to seasonal factors, etc
-Before injecting AGIP GREASE MU EP2 lubricating
grease into the nipples, clean them accurately to
prevent mud, dust or other foreign matters from
mixing up with grease, thus diminishing the lubrication
effect
-When making oil feed or change it is better to use the
same oil type, in order to avoid mixing oils with
different features.
-When executing maintenance activities, keep the
machine rested on the round in horizontal position,
stop engine and disengage power takeoff.
-After the first working hours check that all bolts and
nuts are tightened strongly, especially the hoes’ ones;
remember also to check often all the machine safety
guards.

Sicma S.p.A.
Miglianico (CH)
page 19
FIRST CHECK
After the first 50 hours of work change oil in the gear case and check all bolts and nuts tightening.
EVERY 8 HOURS OF WORK
-Grease with AGIP GREASE MU EP2 the rotor support through the lubricating nipples A
(picture 20) of CS, SA, SD,SF and HLV-HLF tillers.
-Grease the cardan shaft spider of every model of tillers.
EVERY 50 HOURS OF WORK
-Check oil level of sump/bevel gear pair (A- picture 21).
-Check oil level of the lateral drive (A- picture 22),
-Check oil level of the rotor support on ST, SM, SP, RG, SHV-SHF-SHE and SM-F tillers (A-
picture 23).
If necessary feed with AGIP ENI BLASIA 150 80W90 oil.
-On HLV-HLF and SHV-SHF-SHE tillers, check oil of their hydraulic system (cap B– picture
24) and of their mast (cap C– picture 24)
If necessary feed with AGIP OSO 68 hydraulic oil.
-Check that all bolts and nuts are strongly tightened, especially the hoes’ ones.
EVERY 500 HOURS OF WORK
-It is necessary to change oil of the group sump/bevel gear pair, of the lateral drive and of the
rotor support (ST, SM, SP, RG, HLV-HLF, SHV-SHF-SHE, SM-F); use only AGIP ENI
BLASIA 150 80W90 oil.

Get rid of exhaust oil in compliance with the relevant rules of
the country where you operate. It is thus forbidden to pour it
on the ground.
Before executing maintenance activities on the machine, stop
engine, disengage power takeoff, pull parking brake and
place the equipment on the ground.
BLADES REPLACEMENT
To assure a perfect functioning of the machine, check often that its hoes are in good condition and
perfectly fixed by the locking bolts; in case they are broken or bent replace them with new spare
parts, remembering to keep always the original position.
CS, ST, SM, SP, RG, SF, SD, HLV-HLF, SHV-SHF-SHE and SM-F tillers are equipped with 6 hoes
per flange; on CS, ST and SM models it is possible to reduce their number to 4 when particular soil
conditions require this modification.
Before starting the hoes replacement activities, stop engine,
pull parking brake and disengage power takeoff; lift then the
tiller with the tractor elevator and place it on supports to
avoid an accidental fall.
Pay attention to hoes bolts A(picture 25): these ones must be assembled with their screwhead on
the hoes side and their washer and nut on the flange side; bolts, thus, will not unscrew while the
machine is being used.
If you have to replace a sequence of more than one hoe, do it one by one in order to keep as better
as you can the original helical-run position (picture 26).
