1-Safety instructions
Before commissioning, study the instructions and follow the safety guidelines!
In this user guide we have marked with this symbol all hazards or
risks that operators are subject or exposed to.
Signs and security stickers attached to the spreader show you that it is
safe to use the machine: Respecting the instructions = safety
A. Normal use
The spreader is designed and manufactured for normal use as described in this
manual.
Four situations are thereby defined as: parking, loading, transporting and spreading
(Chapter 5).
All uses other than specified are considered non-compliant. However, a number of
predictable non-conform situations are discussed and specifically prohibited. The
manufacturer is not liable for resulting damages.
We must respect the rules of accident prevention and other legal safety
regulations, occupational medicine and the Highway Code.
The manufacturer accepts no liability for damage resulting from an unauthorised
modification of the machine.
B. General safety regulations and accident prevention.
a. Vehicle shutdown: Before
working on the machine, stop the
engine, release the hydraulic
pressure engage the brakes
(tractor and trailer) and remove the
ignition key.
b. Before starting the tractor
engine, ensure that the PTO is not
engaged, that all safety devices
are fitted and in good condition.
c. Never deregulate or
override safety devices. For
settings, care and maintenance,
follow the procedures described in
the manual (especially chapter 6/7)
d. It is strictly forbidden to go
under the vehicle when in
operation.
e. The use of the machine
remains the sole responsibility of
the driver. He must ensure the
absence of third parties in the
proximity during any manoeuvre.
f. Given the residual risk of
shock or damage to the spreading
device (AND its projection area)
and that it is technically impossible
to protect (at least in the work
phase), it is the responsibility of
the driver of the machine to ensure
the absence of a third party in this
area when the machine is in
motion.
g. The driver must be in
possession of all necessary means
to use the machine under optimum
conditions.

Steering axle :
The steering axle follows the vehicle and works from the movement caused by
the curves, it must be locked on the highway (at medium or high speed) and in
reverse.
The self-steering axle is a follower controlled by a cylinder located on the
drawbar of the vehicle, it is a closed hydraulic circuit with accumulators to
maintain pressure. It requires the installation of a clevis on the tractor. Note that
the self-steering Rolland axle can become a follower axle when a tractor is
without a clevis because locking cylinders of the follower axle have been
retained. The advantage of this system is that the driver does not need to
intervene when driving, neither forward nor in reverse.

Hydraulic headland kits:
Hydraulic headland kits are available as options on the frames C8, C11, C12, C22,
C13, C23 for the ROLLTWIN spreaders and C10 for the ROLLMAX spreaders.
These headland kits allow spreading at the edge of the plot. It is possible to have
headland kits on the left or on the right or one on each side.
Weighing :
It is possible to equip the ROLLTWIN and ROLLMAX spreaders with a weighing
system. Weight information is detected by sensors on the drawbar and the axle. The
data is then memorised in the weight conrol box per client or plot. In addition to the
weighing system the user can have a data processing software for managing
customers or plots (storage up to 65,000 weighings). Also optionally available is a
compact printer equipped with a battery rechargeable at the mains that can publish
tickets with weight totals, per customer or plot.

Vehicle coupling system :
The coupling may not exceed the speed of 32 km/h or 20 mph road speed. The
connection is provided by a standard ring (all types of couplings can be used with
hook, ring bolt or spoon coupling).
PROCEDURE
. Make sure that the tractor used can carry the nominal load of
the trailer.
. After coupling the trailer to the tractor, make sure the skid is
raised properly and in the resting position, securely locked.
. Check all lubrication points before the first use (see chapter
Maintenance)
Adjustable tractor coupling(automatic hook or pick-up coupling):
• Approach slowly in reverse, lower hitch to coincide with the ring.
• Once in place, raise the hitch (the ring will position itself).
• Lock the device.
• Raise the hydraulic or mechanical skid.
Fixed tractor coupling (ring bolt, autohitch, drawbar) :
Place the prop in position (ring above the ring bolt coupling or drawbar).
Approach to adjust coupling devices (tractor and machine): :

Brake system :
The spreaders are equipped with three brake systems, each one assuring a specific
function.
When parking, use the mechanical hand brake. During the transport it is the
hydraulic brake that is used. The third system is a safety device for in case the
coupling breaks (a cord between the hand brake and a fixed point on the tractor).
Connect the safety cord in case of breakage of the coupling that operates the
parking brake. Check at the start of every season, the tension of the cable
connecting to the brake rods.
PROCEDURE
. Any trailer with a GVWR more than 1.5 tons is obligatorily
equipped with the braking device. It must be coupled to the
tractor braking system.
Hydraulic braking system :
Install the red hose (4) on the pressure outlet "BRAKES" on the tractor.
Ensure the proper functioning of control and check connections for leaks. Brake
pressure: 100 to 130 bar.

Installation of the drive shaft :
PROCEDURE
. All drive shafts must be equipped with safety guards in good
condition.
. Deteriorated guards must be replaced immediately
. Do not forget to install guards and to restrain them with
chains.
. Never operate a PTO without the foreseen guards.
. Wearing loose clothing may be the cause of accidents.
. During the first use, it may be necessary to adjust the length of the drive
shaft. To do this :
Ensure the correct length of the drive shaft tubes.
Tube can be damaged if the turning circle is too severe
Interlock the tubes a minimum of 4500 mm.
On transmissions there are several types of security, safety shear bolt or torque
clutches cams. In case of a shear bolt, it should be replaced by a bolt of the same
type and same quality as the original. Replacement by a stronger bolt will damage
the vehicle.
N.B : for commissioning, operation and maintenance of the transmission
(primary and secondary), refer to the manufacturer's specific instruction
manuals provided with the machine.

Electrical connections :
1- LIGHTING
The machines are equipped with standard lighting which follow the legal
requirement for road use.
Spreaders are fitted with regulation lighting, for that reason, it is necessary to
connect them to the tractor electrically.
PROCEDURE
. Never leave without checking the operation of the vehicle
lighting: your safety and that of others depend on it.
. Do not leave the wires hanging near the transmission
Connect the multipin (A) without forcing it and in the right direction, the tongue
must be in the slot.
Careful: our wiring is designed to cope with the flow of current independently to the
left and right hand lights. Depending on your tractor a bridge on your tractor socket
may be necessary. If this is the case: Rolland cannot take any responsibilty for an
overheated circuit. This modification is done by the client and is his responsibilty.
2- OPTIONAL EQUIPMENT
Connect the 3-pin plug (B) without force, the direction is indicated by the flat
section.
This socket is present on all machines equipped with electronic boxes or those
equipped with weighing or centralised lubrication.

Installing the self-drive system :
The option of self-steering axle requires the installation of a steering actuator.
Depending on your trailer, one or two clevis forks must be mounted on your tractor.
These are provided but the adaptation and installation are not covered by
ROLLAND. In fact, depending on the make and model of tractor, the forks' position
may vary slightly.
For 1 self-steering axle
For 2 self-steering axles
While the tractor is completely turned (wheel in contact with the
drawbar), verify that approximately 20mm margin at extremeties
of the undercarriage piston rods remains, i.e. that they are not
fully retracted or extended.
Installation of the clevis forks:
The axes of the cylinder swivel and the ring of the drawbar must be at a distance of :
180 mm for mounting in a single cylinder link
120 mm / 160 mm for mounting in a double cylinder link
The axis of the cylinder swivel must be decreased by :
18 mm with respect to the axis of the ring.

Installing the cylinder :
For this operation, no pressure may be present in the circuit. If your installation has
only one cylinder, the automatic latching system allows its installation easily. Simply
attach the cylinder to the tractor and slowly steer it round to lock it. However if your
vehicle has two cylinders on its drawbar, install the cylinders manually.
The adjustment should be made with tractor and trailer coupled
and properly aligned, wheels straight, cylinder(s) attached. It is
advisable to advance in a straight line for about 10 meters.
Make sure the tractor handbrake is engaged.
.
PROCEDURE
Close the circuit selector valve(s)
Open the isolating valves of the different circuits.
Using a hand pump, raise the pressure in the different circuits
Between 20 and 35 bar for mounting a single cylinder with a diameter 40/80 (the
valve on the hand pump must be closed)
Between 20 and 35 bar for mounting two cylinders
Once the pressures are stable (a difference of 5 bar can be tolerated), close the
valves of the different circuits.
To reuse the hydraulic support, simply reopen the valve(s) selector. (make sure
the valves of the self-drive circuit are closed)
To release the pressure from the circuit, the valves on the circuit selector must be
closed, open the valves for the various circuits and open the tap of the hand
pump. The oil then returns to the pump.
Original instruction : French NT0002 V –h – 03/2012

Concerning follower and self-steering axles
Any self-controlled running gear can be used in steering mode. To do this, simply
place the cylinder(s) to the side(s) of the drawbar in the space provided for this
purpose. The axis ball cylinder - tractor clevis then serves to block the cylinders.
The pressure in the circuit must always be released (monitor through the
pressure gauges). For locking the follower axle, a hose, labeled yellow-green, is
located on the hose holder.
Fixation axis
cylinder ball
coupling - tractor
In the self-steering (or forced) mode, it is forbidden to use the
steering axle locking hose, as this may cause great damage to
the hydraulic system. Thus, to avoid any risk of error, it is highly
recommended not to connect this hose (marked by striped
yellow and green markings) to the tractor in self-steering mode.
. Before steering, ensure that nothing is blocking the rotation of the wheels.
It is imperative that the hydraulic system of the axles is purged of all air.
Do not exceed recommended pressures in the process of pressurizing the circuit
because the membranes of the accumulators may be damaged and no longer
fulfill their role.
Concerning the follower axles
For locking the steering axle, a hose labeled yellow-green is located on the hose
holder.
. On the highway in steering mode, it is advisable to lock the
axle(s) to avoid any risk of an accident involving an unplanned
movement of the trailer, especially when your vehicle is laden.

Loading :
Any damage due to overloading is in no case covered by manufacturer's
warranty.
.Never exceed the vehicle payload
.Check the good load distribution on the vehicle
.Check the balance of the load, good stability and
manoeuverability of the vehicle.
. Ensure during loading that no hard substance (stone, pieces of
wood, iron, etc.) is loaded into the spreader, it could cause
damage.
. When used in freezing weather check the mobility of the slats of the bed
before loading.
Transport
The spreaders are designed to travel at 32 km / h or 20 mph (see table) according to
the model. They are approved for the highway.
. Respect the highway code.
. Never leave without first checking the correct function of the
vehicle’s lighting: your safety and that of others depends on it.
. Check the inflation pressure of the tyres (see chapter
Maintenance).
. Moving across a hillside with a loaded hook lift can be
dangerous. To the extent possible, move with the axis of the slope. If not
possible, avoid driving with a load greater than 50% of the nominal load.
. For maximum safety, it is imperative not to exceed a gradient of 15%
(obstacles, ruts, ditches).
Bed shaft counter (hubodometer) optional..
This meter is configured for a wheel type 305 70 R 19.5. If your vehicle is
equipped with different wheels, a correction of the display of the hubodometer is
necessary to obtain an exact distance.

Spreading
Set the PTO in motion without accelerating and bring it to normal speed of 1000
rpm. All ROLLAND spreaders are designed to operate in this regime except in
exceptional cases (540 rpm). In all cases, the plan to use is specified by a sticker on
the hose carrier at the front of the vehicle.
If the quality of the spreading is not satisfactory, several factors may be the cause,
seek the reason among the following points:
Adjust the settings relative to the dung.
The load (irregular, non-homogeneous).
The power of your tractor (too weak).
The speed of the PTO (too slow - monitor the plan). Check the flow.
If a beater jams on the deck, reverse or advance the bed to clear the beaters, stop
the machine (see § 1-1 on page 3) and manually remove the material blocking the
machine from the rear (see page 32). To perform this operation, it is advisable to
wear personal protective equipment (gloves, goggles, helmet, ...)
The controller can also be operated manually in case of failure. To switch to manual
mode you must turn the screw 1 clockwise. From the tightening of the screw the
controller switches to manual mode, then just fine tune as needed. To return to the
electrical control, simply wind out the screw entirely. In case of failure of the
distributor or control box, it is possible to connect the hoses directly to the tractor.

6 – Settings
Preamble: Unplug the power supply before carrying out any adjustments (see
§ 1-1 on page 3)
Adjustments to the mechanical drawbar :
Adjustments to the mechanical drawbar :
The setting of the drawbar enables a level body according to the coupling height,
giving a greater flexibility and a maximum weight transfer to the rear axle of the
tractor.
N.B : For the first commissioning, the dealer will take care of adjusting the drawbar.
PROCEDURE
. Carry out the adjustments on an empty vehicle.
. Operate on a firm, level ground.
. Make sure the parking brake (tractor and trailer) is engaged..
. Install the safety peg above the ring bolt of the tractor..
Put the machine on chocks with the help of a jack (lifting capacity: 5T) placed at
the front of the chassis.
Remove the setting pin of the drawbar (item B).
Position the drawbar so that the spreader is level when coupled to the tractor.
The position of the drawbar will be adjusted to the next higher hole. Thus the
spreader will be slightly nose up.
Replace the setting pin.
Remove the jack.
The top hole is used for large diameter wheels, the distance between each hole
being 7cm.

7 – Care and maintenance
To carry out the maintenance under good conditions, the following safety
rules must be met :
Block the wheels.
Engage the mechanical brake. (hand brake)
Unload the vehicle.
1- Check the brake system (every 6 months)
a- Parking and emergency brake
Verify the correct tension of the parking / emergency brake. The parking brake
lever should not be able to reach the last ¼ of the ratchet. If this is not the case,
tighten the cable.
Procedure for tensioning the cable :
Set the parking brake lever in the off position and ensure the
immobilisation of the vehicle by placing chocks in front and behind the wheels.
Loosen the cable clamps on one side,
Re-tension the cable
Re-tighten the cable clamps
Perform a test
If it appears that the brake rods (see fig.1 below) require too much
angle to allow for efficient braking, take up the play at the pads (see
the following: b)
b- Service brake
Check operation of the brake cylinders, make sure they are not at full-stroke and
control their mounts and the return springs (cylinders should not extend more
than two thirds of their maximum stroke or 100mm).
If this is not the case, proceed to remedy the brake linings.
To do this :
Set the parking brake lever in the off position and ensure the
immobilisation of the vehicle by placing chocks in front and behind the
wheels.
Remove the circlip at the end of the brake cam (see fig1 next page)
Disconnect the link rod of the cam.
Using a pipe wrench for example, exert a torque on the brake cam
simulating the braking.
Replace the link rod on the cam in this position.
Replace the circlip.
N.B :
Original instruction : French NT0002 V –h – 03/2012
30
If your vehicle is equipped with brake slack adjusters, bring the pads
closer by turning the bolt provided for this purpose with a 19 spanner (see
Fig. 2).In a clockwise direction close the bolt until you feel resistance and
then back off a ¾ turn (see Fig. 2).
If your vehicle is equipped with self-adjusting rods, the operation of
lining play compensation manages itself.
Check lining wear through the hole provided for this purpose.
If the pads are unusable or questionable, contact your local ROLLAND
dealer.
Fig. 2
Fig. 1
c- Check wheel hub bearings :
The bearings are wearing parts; their lifespan depends on working conditions, load,
speed and especially their adjustment and lubrication.
To check the play of hub bearings, lift the axle (vehicle shut down (see § 1-1 on
page 3) and empty) so that the wheel does not touch the ground (need for a jack
5T capacity in line under the axle) and grasp the wheel right and left trying to
move it.
Monitor after the first commissioning.
Every 2 years, verify the adjustment of tapered bearings. Excessive play may
damage the bearing seats and braking devices.
d- Checking the hub caps :
For push on caps, visually check that they are fully fitted into the hubs.
For screw caps, make sure they are properly seated at the front of the
hub.

3- Cleaning and lubricating :
Clean the body with copious amounts of water after each transport of corrosive or
soiled goods. After washing, follow up with a general lubrication (oil spray) and verify
the brake functions. For all cleaning and lubrication operations, the machine should
be shut down (see §1-1 of page 3)
Every 10 hours:
-Grease the bed chain drive front and rear
- Greasing of the PTO drive shaft
Every 50 hours:
-Grease the axle, the drawbar and the drive shaft bearings
1 to 3 times/year (depending on use intensity) :
- Grease the beater bearings (to the right of the TCE, at the top of the verticals
(in the upper casing)) Provide adequate means of access (see page 32)
-Grease the drive shaft bearings
The grease points are represented by red dots on the diagram below. The oil of the
various mechanical boxes (gearboxes, gearbox and bevel) should be replaced every
year or every 200 hours in accordance with the amounts shown in the "maintenance
of mechanical boxes." The recommended oil is SAE 140.
Original instruction : French NT0002 V –h – 03/2012

Instructions for cleaning
Caution: this operation requires special precautions in addition to those cited
throughout this document (pages 3, 17, 20 and 26 in particular) and in this chapter.
Mandatory:
Ensure the machine is stopped and the discharge of the device is
complete.
Use the side ladder for this purpose
Warning, there is no means of access to the interior of the vehicle.
If, however, an intervention inside the body is required, equipment (not
supplied) type scaffolding must be used to enter, with railings and other safety
precautions. In general, all interventions higher than the floor must be done with
adequate means of access.
All interventions, which are more toward the back of the machine, must
be done with the machine off, PTO disconnected and using personal protective
equipment (goggles, gloves etc..) recommended for the use of specific tools by
their manufacturer for example :
High pressure cleaner for washing the screws and beaters
A cutting tool to cut the strings
Etc
The rotation of the bed and all other functions (slurry door, hood) are
sometimes necessary. All our machines permit these functions independently of
the rotation of the PTO. This ensures the non-rotation of moving parts particularly
with the " autonomous control". In fact in the latter case, a connection kit comes
with the machine (see pages 10 to 13) to allow the bed to be supplied directly
with oil from the tractor.
Original instruction : French NT0002 V –h – 03/2012

4- Adjustment of the bed tension :
This adjustment must be performed every 50 hours of use. It prevents premature
wear of components and keeps the chains in position. To carry out the tension
adjustment of the 2-chain there are 2 stretchers (A) outside the skip, for the 4-chain,
there are the two tensioners (A) and 2 more (B) in the middle.
Loosen the counter-nuts A
The tensioning of the bed is done by compressing the spring by tightening the
nuts B
Proper tension translates into a lift-off between 5 and 10 millimeters of the first
bar of the bed in relation to the guide plates under the spreader.
Tension control to be performed every 10 hours (adjust tension if
necessary)
Original instruction : French NT0002 V –h – 03/2012
35
5- Steering axle :
Checking and adjusting the alignment
Immobilise the vehicle, the steering axle well inline, lock cylinders retracted, on a
level surface.
Measure the distance between the front wheels and the rear follower axle. The
same value should be found.
If this is not the case, unblock the 2 lock nuts of the coupling rod, and rotate it in
order to get the distance at the front to be identical to that at the back.
Tighten the lock nuts firmly.
The coupling rod
Lock nuts
Adjusting the locking cylinders
Periodically check the cap-nut and its lock-nut. After the alignment, proceed to
adjust the locking cylinders as follows
Unscrew the lock-nuts
Screw on the cap nuts.
Develop and maintain pressure in the cylinders.
Unscrew the cap nuts to have them pressing against the stops
Screw down the lock-nuts firmly in order to lock the setting.

6- Maintaining the regulator and hydraulic unit :
Shutdown the vehicle (see §1-1 of page 3)
Check the oil level and tightness of the tank. Remember to change the oil and
regulator filter every year. To change the filter, unscrew the protection bowl (red).
Clean the inside of the bowl with a cleaning agent (do not use cloth or paper
towels), change the filter and then replace the bowl.
Check the oil level of the gear-box. Make a first oil-change after 50 hours of use
and thereafter annually at least.
Check the condition of the hose.
7- Bed control :
Shutdown the vehicle (see §1-1 of page 3)
Check the wear of chain drives and bearings, lubrication is mandatory
(centralised lubrication).
Check the condition and fastening of the bed slats.
8- Transmission maintenance :
The maintenance of this element is primordial for your safety.
Shutdown the vehicle (see §1-1 of page 3)
Check as often as possible the protection cover of the universal joints
Lubricate the various elements of the PTO and the bearings of the shaft
(periodicity page 31).
Check the wear of shims on the drive shaft and the lubrication.
Lubricate also the universal joints at the ends of the angle transmissions.
To optimise the function directly from the tractor a reflux without brake (push-pull
type) is recommended.
- Output tractor direct about 60L/min for a manual control type MTKA,
otherwise risk of overheating and possible engine failure.
- Output tractor 80L/min for a proportional type regulation with an
electrical control in the cab
- Every year, change the oil in the reservoir, change the regulator filter
and change the unit mesh filter.
WORK ON ANY ELEMENT OF
TRANSMISSION (SHAFTS, CARDANS,
BEARINGS, ...) MUST BE DONE ONLY ON A
FULLY SHUTDOWN MACHINE (STOP THE
TRANSMISSION AND TRACTOR ENGINE).
REMOVE THE KEYS
Original instruction : French NT0002 V –h – 03/2012

11- Wheels and tyres:
Check the wheel nuts and tyre pressures regularly
Inflation
Proper inflation of tyres allows optimum grip, comfort and performance. Also the
tyres will last longer and the surfaces will be preserved.
We strongly discourage:
- An under-inflation, which distorts the carcass and may cause a tyre failure.
- The over-inflation which reduces the area of contact with the ground
resulting in a loss of adhesion. In addition the casing is more sensitive to
shocks.
Assembly
Mount the tyres only on the rims they are designed for.
Use rims clean and in good condition, working with clean surfaces.
Use the appropriate tools for the tyres and rims.
To facilitate assembly and disassembly, lubricate the seating (green) and the
beads of the casing (black) with a suitable product as shown in the sketch below.
With a new tyre, use a new inner tube. Use an inner tube corresponding to the
size of the tyre.
After mounting a tyre, ensure the correct centering of the tyre on the rim: if this is
not the case, inflate, deflate and inflate again until the centering is good. Always
use the maximum pressure for positioning the beads on the rim seat 2.5bars (35
psi). Then adjust the pressure to use or to store.
When transporting the equipment by road, rail or boat, you must inflate the tyres
to 2.5 bar (35 psi) to avoid damage from the mooring systems.

Procedure for mounting the silage doors (option Rollmax)
Before installing your silage door, you must remove the beater frame of your
spreader. The operation must be performed by your ROLLAND dealer, the only
ones authorised, trained and to have the tools.
Procedure for removal of the tool frame
Disconnect the secondary drive shaft
Using slings, hook the framework to an overhead crane (minimum
capacity 2.5 tons for the slings and the crane). The attachment points are
specified in the following diagram. The weight of each subassembly is
specified by stickers.
Loosen and remove the fixing bolts of the body.
Remove the frame using the crane and place it on its support. Fix it to
the support, using the nuts and strap(s) provided. After checking the tightness
and stability, the slings can be removed.
In the absence of a frame support, place the frame flat on the floor on
the hatch side.
Silage panels :
After having smeared with grease, install the rear posts. The grease
facilitates their mounting and demounting because adjustments are optimized

After having smeared with grease, install the side panels. The grease
facilitates their mounting and demounting because adjustments are optimized
to ensure the tightness of the assembly. Fix to the body of the spreader using
the bolts provided.
On the ground assemble the panel with the top rail by means of the
axes provided. Be careful to put in place the pins to lock the assembly.
By means of a crane, a hoist or a loader put the assembly in place,
panel + traverses. Then fasten the side panels using the bolts provided.
Complete by installing the cylinders with the drum on the body side.
For all operations carried out at heights, a means of access, type scaffolding,
must be available, respecting the standards for this type of equipment and
respecting the standards for this type of product (railings, etc ...).
The cylinders for opening the silage door "LOULOU" are fitted with
dual control valves. Beware of any residual pressure present
between the valve and cylinder.

ANNEX 1
INSTRUCTION FOR USE OF THE HYDRAULIC DRAWBAR
SUSPENSION
1- PRESENTATION OF THE SYSTEM
All drawbars with a damping system rather than a mechanical leaf
spring but consisting of elements using hydraulic technology are called drawbar with
hydraulic suspension.
The system is governed by the tractor. The operator can correct at any
time the height of the drawbar.
2- OPERATING PRINCIPLE
The system is mainly composed of the following elements :
Component
Quantity
Illustration
Suspension cylinder
2
A drawbar suspension
unit equipped with 2
diaphragm
accumulators
1
Drawbar

Original instruction : French NT0002 V –h – 03/2012
49
The various elements are assembled according to the following plan :
3- RECOMMENDATIONS FOR SETTINGS AND USE
The drawbar should be adjusted so that the chassis of the trailer is
horizontal.
However, some cylinder movement must be possible to absorb dynamic
impacts ( 3cm)
2 modes of operation are possible :
The operator predefines once and for all its coupling height. In this case he
may leave the supply hoses unconnected on the tractor. It should be noted
that the drawbar works in closed circuit; that is to say that when loading the
spreader, the spreader will sink down, when you start tipping, the cylinders will
again be deployed and no correction will be possible.
This method is strongly discouraged despite a possible saving of a
distributor on the tractor.
Or the user leaves the hoses permanently connected to the tractor. This will
allow an instant correction of the height of the drawbar to compensate for the
movement of the cylinders due to the load variation in the vehicle.
Such use is the "normal" use of the system.
By working this way we obtain the maximum suspension flexibility.
N.B : 2 adjustments are possible at the upper catch of the cylinder. The
method for changing the catch is identical to that of the sprung drawbar (see
page 28)
Original instruction : French NT0002 V –h – 03/2012

ANNEX 2
INSTRUCTIONS FOR THE PASSIVE SUSPENSION OF AN
Axle (closed circuit)
1- PRESENTATION OF THE SYSTEM
All axles are equipped with an independent damping system that are
said to be with passive or closed circuit suspension.
.
The circuit is completely independent of the tractor. The suspension is
set once and for all (even though it is changed occasionally). The adjustment is
made so that an optimal displacement is supported. The cylinder movement being
200 mm, the optimal displacement is ± 100 mm.
The user cannot correct the height of his vehicle on the move.
2- OPERATING PRINCIPLE
The system is composed mainly of the following components:
4 suspension cylinders for a vehicle with 2 axles (6 for a 3-axled
vehicle)
1 hydraulic suspension control block
2 piston accumulators

2 comments :
A system for counter roll of the vehicle is provided in the assembly. Oil will never
"take the easy route". The load will constantly be equal over the four wheels, which
allows us also to "dispense" with tipping stabiliser.
The pressure relief valve is intended for smoothing out any abnormal pressure
peaks (violent dynamic shocks).
3- RECOMMENDATIONS FOR SETUP AND USE
a. To increase the height of the suspension (raising the body) :
To add oil to the suspension system (if, for example, the height is
considered insufficient), proceed as follows:
Connect the hose identified by a marking (long green) to the tractor.
Open the two outer taps of the block (see photo). The middle tap must be
closed.
Supply the oil circuit via the hose connected to the tractor until the required
height is achieved.
Close the two outer taps again and open the middle tap.
Release the residual pressure present in the hose by positioning the tractor
distributor on "float"
Disconnect the hose (long green) from the tractor.
Only the return drain hose (short green) remains connected.
WARNING Note that the height of the skip will vary depending on
the load present inside.
Original instruction : French NT0002 V –h – 03/2012
52
b.To decrease the height of the suspension (lower the body) :
To remove the oil from the suspension system (for example, if the
height is considered too high), proceed as follows:
Connect the hose identified by a marking (long green) to the tractor.
Open the two outer taps of the block (see photo). The middle tap must be closed
Set the relevant distributor of the tractor on position "float" until the required
height is achieved.
Close the two outer taps again and open the middle tap.
Release the residual pressure present in the hose by positioning the tractor
distributor on "float".
Disconnect the hose (long green) from the tractor.
Only the return drain hose (green short) remains connected.
RECOMMENDATIONS FOR USE :
The hose used to adjust the height of the skip should be connected only in case of
need to work on the suspension. In normal operation, this hose should be stored on
the hose holder.
In contrast, the hose "drain" (oil reflux by high over pressures) must be permanently
connected to the tractor.

ANNEX 3
INSTRUCTIONS FOR THE HYDROPNEUMATIC SUSPENSION
OF AN AXLE (open circuit)
PRESENTATION OF THE SYSTEM :
All undercarriages equipped with a damping system with instant
automatic level correction are said to have hydropneumatic suspension.
The system is permanently coupled to the tractor. The ideal is to
provide a single acting valve (LS if possible) and a free return to the source.
Pressure can also be taken at the pump outlet without using a distributor since a
continuous pumping is required.
The vehicle corrects its height instantly, which is to say that when
loading the vehicle, the hydraulic system will demand the tractor to re-adjust the
height of the skip and vice versa, during unloading, the system will return oil to the
tractor..

3. RECOMMENDATIONS FOR SETUP AND USE
3-1 Initialisation of the system :
Like with any electronic control system, an initialisation is required so
that the system is able to instantly know its position relative to its upper and lower
limits.
The initialisation consists of the detection, validation and memorisation
of the upper and lower limits.
- Initialisation procedure :
A blinking 1-1 appears on the box (see decoding blinks p8-9)
Using the red button, fully raise the suspension manually. Do not release the button
until the cylinders are completely deployed (200 mm travel)
Wait 2 seconds in the upper position.
Using the red button, fully lower the suspension manually. Do not release the
button until the cylinders are completely retracted (the vehicle must be
horizontal)
Wait 2 seconds in the lower position.
Return to the "auto" mode by tilting the green button.
The vehicle will automatically find its position and the LED lights permanently on
the box
Remarks :
The initialisation parameters are stored in the box. It is not necessary to restart the
process at every power up of the system. Initialisation has already been done in the
factory. An initialisation on-site may be required only in case of an intervention on
any of the system components.
If the vehicle does not automatically find its position and blinking 1-1 on the box
indicator continues, it means there is a problem at one of two sensors at the rear
(bad adjustment range) contact us.
3-2 : Decoding the blinking of the box indicator :
When the control box light flashes, the operation is not in a "normal" state.
Either the system is in its initialisation phase (blinking 1-1)
Or the system has detected an anomaly. The system therefore closes down.
No action is possible (automatic or manual mode).
The system is able to detect the following defects :
Failure or breakage of the wire link of the position sensors (electrical
connection)
Original instruction : French NT0002 V –h – 03/2012
56
Overload or breakage of the wire connection of the solenoids (electrical
connection)
If one of these fault situations occurs, the lamp flashes and the solenoid control
switches off for safety reasons. Similarly, in manual mode, no function can be
executed.
The user must validate the fault by switching off the power to the electronics module
for 3 seconds and then putting it back on.

REMARKS :
Several options can be grafted onto this system.
4-1 : Option lift axle :
An option "lift axle" is available on this type of suspension. This option
relieves the front axle or lifts the front wheels completely.
This function replaces fully the weight transfer (or tipping stabiliser)
.
: If vehicle is equipped with a steering axle (or forced follower), it is
strictly forbidden to raise the front axle at a medium or high forward
speed (on the highway). The function should be used only when tipping
or by lack of grip traction on the ground, for example, as in the case of
the spreader.
4-2 : Load weight option :
A load weight option is available for this type of suspension.
A battery of three pressure sensors measures the hydraulic pressure at
different locations within the system. This pressure information is transcribed to a
box in the cabin which gives us information on the load in the vehicle.
A patent for this system has been applied for by Ets Remorques ROLLAND
