When the symbol "Attention" appears in the manual it means that the safety of the operator, assistant, bystander, or the normal operation of the
machine, could be in danger. It is essential that all safety instructions are
observed. It is vitally important to make sure that all users have the opportunity to read and thoroughly understand these instructions.
Correct use
The AXERA M fertilizer spreader is designed to spread dry, prilled and granular fertilizer as well as seeds. Any other use is inappropriate and any defects arising therefrom will invalidate the manufacturer's warranty; any risk associated therewith is
borne entirely by the user. Correct use also entails the full compliance with all operating, maintenance and repair instructions issued by the manufacturer.
The spreader should only be used, maintained and repaired by persons who are familiar with the machine and who have received instructions with regard to potential
dangers.
All current appropriate accident prevention requirements and all other general recognised safety, technological work-related and road traffic legislation must be observed.
Any warranty claims against the manufacturer for damage resulting from unauthorized alterations to the machine will be ruled invalid
Driving on public roads
When driving on public roads and paths, ensure that the tractor/spreader combination
complies with all relevant road traffic regulations. (Overall permissible weight, overall permissible axle weight, lighting warning signs, guarding, etc.)
Attention: Pay attention to correct front axle weight!

Accident prevention and safety issues
Most accidents happen because someone ignores the most elementary safety rules
during operation, maintenance or transport. It is vital that all persons coming in contact with the machine - the purchaser himself/herself, a member of his/her family, an
employee, a bystander - strictly obeys the following main safety rules. Other safety
instructions are to be found on the decals placed in various prominent positions on
the machine.
♦ Observe all safety notes contained in this Operators Manual and all current statu-
tory safety and accident prevention regulations!
♦ Before every operation, check nuts and bolts and other fixings for tightness, espe-
cially those of the spreading discs and spreading vanes. If necessary, tighten to recommended torque settings.
♦ Before using the machine, operators must familiarize themselves with all parts of
the equipment and the function of all controls and adjustments. Finding out during operation may be too late.
♦ Before every operation, ensure that the tractor spreader combination complies with
all relevant road traffic, as well as health and safety regulations.
♦ When filling the hopper, lower the spreader to the ground and switch off the trac-
tor engine. Remove ignition key before leaving the tractor cab. Make sure shutter
controls are closed.
♦ Before adjusting or undertaking other work such as cleaning, lubricating or carry-
ing out operations on the spreader, disengage the PTO, switch off the tractor engine, wait until all moving parts have come to a stop and remove the ignition key.
During control or repair work, make sure no one can switch on the unit by mistake.
DANGER = Power driven parts !
Never put hands, feet or clothing anywhere near moving parts. Never reach into the hopper - moving parts !
Always avoid wearing loose clothing or clothing with
loose parts that are liable to come into contact with
moving parts.
♦ Keep the hopper free of any foreign bodies.
♦ Before starting the spreader, make sure that nobody is within the danger area a-
round the machine. Make sure you have a good view all round and keep a special
watch out for children!
♦ When outside the area of work the spreading mechanism must be disengaged.
♦ Only start up the spreader when all safety devices and guards have been properly
fitted.
6
♦ Never leave the spreader running unattended.
It is illegal and dangerous to carry passengers when using
or transporting the spreader.
Attention: ! Danger from revolving discs and fast moving spreading material. Make sure no one is within the
spreading zone around the spreader before engaging
the PTO shaft/spreading discs!
♦ Before leaving the tractor seat, lower the spreader on to the ground, switch the
tractor off and remove the ignition key. With single acting hydraulic shutter controls, switch off the hydraulic hose shut-off valves.
♦ Parking the fertilizer spreader without
being attached to the tractor : only with an
empty hopper and on firm, level ground.
♦ Never allow anyone to enter the space between tractor and spreader without first
making sure that the tractor is prevented from moving by means of a parking brake
and/or wheel chocks.
♦ It is absolutely forbidden to remain between tractor and fertilizer spreader during
operation
♦ Before attaching or removing the spreader from the tractor 3-point linkage, make
sure that the control valve is positioned so that inadvertent lowering or raising of
the linkage is impossible.
♦ It is recommended that the condition of the spreader is checked by a recognised
dealer at the end of every season. Especially disc vanes and fixings.
♦ In the event of a failure during operation, switch off the spreader immediately.
Stop engine and remove the ignition key before checking and repairing the damage.
♦ PTO shaft and shaft protection damage must be repaired immediately before using
the spreader. WARNING: Power driven parts : this is a danger zone which can
cut or crush.
♦ Ill advised choice or use of fertilizer or other spreading material can cause serious
damage to people, animals, plants and the environment. Choose the correct material for your application. Handle with car and carefully follow the manufacturer's
instructions.

Warning
Maximum attachment height of the fertiliser spreader!
Danger of injury by unintentional contact
with the spreading discs.
As protection against unintentional contact with the discs, the maximum attachment height of 1500 mm from the un-
derside of the guardrail to ground level must not be exceeded.
If this attachment height is insufficient
when in normal spreading mode, the late
top dressing mode position (attachment
height 0/ 6) should be used.
Essential safety instructions for the hydraulic system
♦ Hydraulic circuits contain oil under high pressure.
♦ Mark all hydraulic connections between tractor and implement at both coupling
sockets and plugs in order to avoid incorrect connection.
♦ Follow correct connecting instructions of hydraulic cylinder and motors. Inter-
changed hoses could cause the opposite effect to that expected.
♦ When connecting the hoses to the tractor, ensure that the hydraulic pressure in
both tractor and spreader has been relieved.
♦ Use suitable protection when locating leaks (safety goggles, gloves, etc.) in order
to avoid injury. Hydraulic fluid escaping under high pressure can penetrate the
skin and cause serious injuries! In case of injury, immediately consult a doctor, as
there is serious risk of infection.
♦ Before working on the hydraulic system, lower the fertilizer spreader on to the
ground, relieve the system pressure, switch off the engine and remove the ignition
key.
♦ Prior to coupling or uncoupling fittings, carefully clean all hydraulic connections.
♦ Operational time limit of a hydraulic hose line is six years from the date of manu-
facture. The manufacturing date of a hose is indicated in month and year on the
hose armature.
♦ The useful life of an undamaged hose should be limited to six years, including a
possible maximum two-year stocking period.
♦ Even when carefully stored and correctly used, hoses and hose connections un-
dergo natural aging. Therefore, their stocking and operational periods should not
be exceeded.
♦ Replacement hoses must meet the technical specifications quoted by the spreader
manufacturer.

2. Preparation of the fertilizer spreader
Take special care when attaching/detaching the fertilizer spreader
to/from the tractor.
2.1 Attaching to the tractor
The fertilizer spreader AXERA M can be attached to Cat.II tractor linkages. Attachment to Cat.III tractor linkages is only possible using Cat.II geometry and placing reduction sleeves over upper and lower linkage pins. A second lower link connection is provided as standard and allows a higher attachment height to the tractor
of approx. 140mm. The upper and lower pins must be secured in place with the
linchpins attached to the spreader.
For correct horizontal spreading of fertilizer, the fertilizer spreader must be attached
as per dimensions given in the spreading charts.
Pay attention that the spreader is mounted at right angles to the direction of travel, is
perfectly horizontal and that the 3-point frame is correctly restrained from sideways
movement to avoid the unit swinging from side to side during operation.
Important: If the lower link pins are in the upper connection point then the top
link pin must also be placed in its upper connection point, to avoid poor load distribution between upper and lower links.
2.2 Parking the fertilizer spreader
The spreader can be parked on the frame, support rollers or parking stand (support
rollers & parking stand are optional equipment).
When parking the spreader pay attention to the following :
♦ When operating the external tractor 3-point lift control lever, do not stand between
the tractor and the spreader.
♦ Before uncoupling the spreader from the tractor make sure that all weight from the
upper and lower linkage coupling points is relieved.
♦ Only park the spreader when the hopper is empty and on a firm level surface.
♦ After disconnecting PTO shaft and hydraulic hoses from the tractor, place them in
the holders provided on the spreader.

2.3 Fitting the Tele-Space pto shaft (spreader side)
Only pto shafts supplied or recommended by the manufacturer should be used. The
fertiliser spreader is equipped with a pto shaft that corresponds to the implement's
technical characteristics and power requirements. It should not be replaced with
shafts with other specifications.
When first attaching the spreader to the tractor, the length of the shaft must be
matched and, if necessary, shortened to fit the tractor correctly.
Read the pto manufacturer's operator's manual carefully, taking special note of the
instructions concerning the shortening of the shaft. This operator's manual can be
found attached to the pto shaft.
If the pto shaft is too long, both pto drive and the spreader may be damaged when the
unit is raised.
The Tele-space pto shaft allows additional free room for easy coupling of the fertiliser spreader to the tractor.
DANGER
Fitting and removing the pto shaft (fertiliser spreader side)
Injury or death hazard due to rotating shaft.
• Before fitting or removing the pto shaft, make sure that the cou-
pled spreader is secured by support blocks to avoid unintentional
lowering and that the tractor is choked to avoid unintentional
creeping.
• Before fitting or removing the pto shaft, make sure that the pto
drive is disengaged, the tractor engine is switched off and the ignition key is removed!
• Always respect correct fitting and securing of the pto shaft. The end marked with
a tractor symbol must be fitted on the tractor side.
Remove the cover (1) from the bell protector
guard.
Fit the pto shaft onto the drive stub and secure in
place with the hexagon nut and bolt (2) and (3).
14
Refit the cover (1) into its original place.
• Make sure that pto shafts, protector tube and end gaiter, as well as extension gai-
ters on the fertiliser spreader side, are correctly in place and in good condition!
• Do not use the safety chain to support the shaft when not in use.
• Before engaging the pto drive, make sure that the correct tractor pto speed is se-
lected to match the implement.
• When detaching the pto drive shaft, place in the holder provided on the fertiliser
spreader.
IMPORTANT
Drive shaft damage when engaging the pto drive
The pto drive shaft and the agitator drive can suffer damage if the
pto drive is engaged at high tractor engine speeds.
• Engage the pto drive at lower tractor engine speeds to avoid
sudden overload to the drive shaft and agitator drive.
• With abrupt engaging on hydraulic tractor pto drives, it is rec-
ommended that a pto incorporating a friction clutch is used.
Additional information for the fitting of pto shafts equipped with a friction
clutch (optional equipment).
WARNING
Friction clutch injury hazard
Pto drive shafts with friction clutches not conforming to recognised
standards can cause serious injury.
• The friction clutch must always be installed on the spreader si-
de.
• For safety reasons an additional extension guard must be fitted
to the spreader side when using a pto drive shaft equipped with
a friction clutch.
• Should a pto shaft with friction clutch be fitted after the ma-
chine has been delivered, the extension guard included with the
shaft must be fitted onto the spreader.
• It is recommended that the friction clutch be checked by a pro-
fessional workshop for correct functioning at the end of each
season.
