SAFETY
SAFETY IN THE WORKPLACE
Most of the accidents, which occur while the operator is using the machine or the equipment or
carrying out maintenance and repair activities, are caused by the non-compliance with the main
safety requirements.
Therefore the potential risks must be fully understood and special attention must be paid to the
activity which is being executed.
If potentially dangerous situations are known,
accidents can be prevented!
USER'S REQUIREMENTS
The equipment user must have the following:
Physical: good sight, co-ordination and capability to execute all instructions in a safe manner.
Mental: the users must understand and follow the prescribed norms, rules and safety measures.
They must be careful, pay attention to their own safety and the safety of other people and act
properly and in a responsible way.
Training: the users must read and understand this manual, its pictures and charts, and the
identification and hazard plates. They must be specialised, trained and qualified on any use and
maintenance activities.
WORK CLOTHING
The following clothing and personal protective equipment must be used when working and
executing maintenance and repair activities:
•Overalls or any other comfortable outfit; make sure that they are
not too loose since they might be caught by moving parts.
•Protective gloves.
•Goggles or mask to protect the eyes and face.
•Safety helmet
•Safety shoes.
Make Sure that personal protective equipment is
properly stored and complies with the laws in force.
GENERAL SAFETY NORMS

accessories when the equipment is running.

SAK Tillers
Page 9 of 23
Prepare the work:
•Do not drink alcohol; take drugs, or any other substances which may affect your ability to use the
equipment before or when working.
•Make sure that there is sufficient fuel in the tractor to prevent the machine from stopping during work.
•Do not use the equipment under unsafe conditions, e.g. do not make temporary repairs just to start
or keep working; do not work at night if the area is not well illuminated.
When working or executing maintenance activities, remember:
•The labels and stickers providing instructions on the use of the equipment or information on
dangers must not be removed or hidden, and must be legible.
•Do not remove the safety devices, covers and safety guards, unless maintenance activities are
being carried out. If the safety devices must be removed, turn the engine off, remove them
correctly and re-install them before turning the tractor on.
•Do not lubricate, clean or adjust moving parts.
•Use the appropriate tools to execute maintenance or adjustment activities on the equipment.
•Do not use damaged or unsuitable tools, e.g. pliers rather than wrenches etc.
•Prior to carrying out activities on hydraulic lines under pressure, or disconnecting their components,
make sure that the line is no longer under pressure and that it does not contain any hot fluids.
•Check all the fittings and make sure that they are well connected before supplying pressure to the
hydraulic lines.
•Make sure that no tools, clothes or any other materials are left in areas where moving parts are
present when the maintenance and repair activities are completed.
•Do not give directions and make signals at the same time during a manoeuvre. Manoeuvre
directions and signals must be given from one person only.
•Do not unexpectedly call an operator, if not necessary. Do not startle the operator, e.g. by
throwing objects.
•Pay attention to people in the vicinity of the work area, especially children!
•Make sure that nobody is standing in the working range of the equipment.
•Do not use the equipment to lift people.
•When the equipment is not needed, turn the engine off; leave the vehicle on a flat surface, with the
first gear and the parking brake engaged. Disengage the power take off.
•Do not execute any cleaning, lubrication, repair or adjustments when the engine is running and the
equipment is in the raised position.
•Do not work on steep slopes, if the stability of the vehicle can be jeopardised.

followed.
SETUP
ATTACHMENT TO THE TRACTOR
Carefully read this instruction manual and the manuals of the tractor and PTO shaft
manufacturer. All tillers are built to be attached to any tractor equipped with a three point lift
of the correct category and with suitable ball ends.
Before attaching the equipment to the tractor, make
sure that the ground is smooth and flat and that
nobody is standing between the tractor and the tiller;
slowly move the tractor towards the tiller by
aligning the tractor lifter arms with the two tiller
coupling side pins; turn the engine off and pull the
brake.
It is possible to adjust the attachment position
releasing the bolts B (picture 1) and modifying the
position of the plates A. Tighten the bolts after
making any adjustment.
picture 1
After adjusting the couplers, connect the lower arms by removing the catch pins from the pins
located on the hitch blocks, inserting the lift arm pins through the hitch block and ball ends and
secure them by means of the pins which were previously removed.
Connect the tractor top link to the third
upper point by removing the pin located
between the two plates, inserting the top
link and securing it by means of the pin.
Adjust the top link so that the upper part of
the frame is parallel to the ground. Block all
the linking parts by means of the sway chains
or arms.
Make sure that the central unit axis (case/bevel
gear pair) is parallel to the ground, thus
minimising the stresses on the power take off
and increasing the working life of the
equipment.
picture 2
After executing all of the above activities, make sure that all
the nuts and bolts are tightened.

SAK Tillers
Page 11 of 23
CONNECTION OF THE PTO SHAFT
Before installing the PTO shaft make sure that the RPM rating and the direction of rotation
match those of the tractor. Carefully read the PTO shaft and tractor instructions.
Furthermore, accurately read the instructions of the manufacturer of the PTO shaft and
of the tractor.
Before starting any activity, make sure that the guards are installed on the power take off
of the tractor and PTO shaft. Make sure that they cover the PTO shaft throughout its length.
When fully extended, the plastic pipes must overlap by at least
1/3 of the length of the pipes (LT). When retracted, the min
acceptance clearance is 5cm (picture 3).
Check that the PTO shaft min. and max. lengths
are within the parameters of the
machine-tractor coupling. Should problems
arise, contact your dealer. After the
installation, anchor the PTO shield to the
tractor and machine using the special chains;
make sure that it turns smoothly. If the PTO
shaft is equipped with safety devices, e.g.
torque limiters or free-wheel devices, install
them on the operative machine side. For the
use and maintenance of the PTO shaft,
please refer to the relevant manual.

SAK Tillers
Page 12 of 23
WORKING DEPTH ADJUSTMENT
The working depth of the equipment depends on the position of the lateral skids.
If the skids are raised, the working depth increases; if the skids are lowered, the working depth
decreases.
Make sure that the skids are set at the same height on both sides.
To adjust the working depth on the SAK tillers loosen
and remove nut A (picture 4) and adjust the skid height
according to the holes B. When the adjustment is
completed, tighten the screws.
DRAG BOARD ADJUSTMENT
The height of the rear drag board can be
adjusted, making the ground more compact
and smooth. Release the chain A (picture 5)
and reengage it at the desired height B.
These activities must be carried out with the engine off, the power take
off disengaged and the hand brake applied. If needed, lift the equipment
and place it on supports, thus preventing any injuries that might be
caused by a sudden fall of the equipment.

SAK Tillers
Page 13 of 23
CHAIN ADJUSTER
The SAK tillers are equipped with a chain drive (picture 6).
The chain adjustment is made during assembly; any adjustments when using the machines, must be
carried out by an authorised dealer or work shop.
START UP
After carrying out these adjustments, the equipment is ready for use. When at the working area, do
not start the power take off with the tiller in working position in the ground. Be sure to lift it by a
few centimetres using the tractor lift. Start the engine, engage the power take off, and lower the
equipment to its working position and start.
ROAD TRANSPORT
With reference to road transport, follow local traffic regulations.
SHUT DOWN
The following activities are recommended if the tiller will not be used for a long period of time:
1 Clean and dry the equipment.
2 Inspect the equipment and replace the damaged or worn parts if necessary.
3 Tighten all the screws and nuts.
Lubricate and cover the machine with a tarpaulin and store it in a dry place.

MAINTENANCE
Maintenance is crucial for the working life and efficiency of any agricultural equipment. If the
equipment is properly maintained and operated, a long working life and operator safety are
assured.
The maintenance intervals indicated in this booklet are provided as a mere reference and are
related to normal working conditions; changes may occur depending on the type of activities,
environmental dust, seasonal factors, etc.
Before injection lubricating grease into the grease fittings, clean
the fittings to prevent mud, dust, or any other foreign matter
from contaminating the grease and reducing the lubrication
effect.
When adding or changing the oil, use the same type of oil to
prevent mixing oils with different features.
All maintenance activities must be carried out with the tiller
resting horizontally on the ground.
After using the equipment for a few hours

SAK Tillers
Page 15 of 23
FIRST CHECK
•After 50 working hours, change the oil in the gearbox and make sure that all the screws and
bolts are tightened.
EVERY 8 WORKING HOURS
•Grease the rotor support through the grease nipple A (picture 7).
•Grease the PTO shaft crosses.
EVERY 50 WORKING HOURS
•Check the oil level in the gearbox (A - picture 8) and in the side transmission (A - picture 9). If
needed add SAE EP 80W90 oil.
•Make sure that all the screws and bolts, especially on the blades, are tightened.
EVERY 500 WORKING HOURS
•Change the oil of the case/bevel gear pair, side transmission and rotor support; use SAE EP
80W90 oil. Contact the closest dealer for this maintenance activity.
The old oil must be disposed of in compliance with the local laws
where these activities are carried out; do not spill or dispose of
waste oil on the ground.
The maintenance of activities must be carried out with the engine off,
the power take off disengaged, the parking brake engaged, and the
equipment placed on the ground.

BLADE REPLACEMENT
To assure the optimum efficiency of the machine, make sure that the tiller blades are in a good
working condition and that their bolts are tightened; replace them if they are broken or bent.
The new parts must be installed in the original position.
Before replacing the blades, turn the tractor engine off, pull the
parking brake, disengage the power take off, raise the tiller using the
tractor lift, and install supports to prevent accidental dropping of the
machine.
Pay special attention to the bolts A on the blades (picture 10): the screw head must be placed on
the blade side, with the washer and the nut on the flange side, so that the bolts cannot loosen
while the equipment is being used.
When several blades must be replaced, replace one blade at a time, so that the initial helical
layout is maintained (picture 11).
