that purpose (ladder, platform). It is strictly forbidden to penetrate into areas behind protective grids or to
press on them.
Before any intervention on the machine, make certain that it cannot be started up accidentally.
All remote controls (cords, cables, control rods, hoses, etc.) must be positioned in locations planned for so
that they cannot accidentally trigger a manoeuvre causing risk of accidents or damage.
Before any use, check tightening of screws, nuts and couplings. Re-tighten if necessary.
Before any use and after each setting or maintenance operation, make certain that all protection devices
are in place and in good condition, and that their locking systems are engaged. It is strictly forbidden to
take or to disable any security devices (we herewith inform and warn you about the risks of serious
injuries, so as contusions, loss of a body part, bone fracture which can even go up to danger of death). In
those cases where during repair or maintenance it should be necessary to dismantle certain security
devices, it is absolutely necessary to re-assemble these devices immediately after repair or maintenance
works.
Make certain that the parcel of land does not have irregularities or debris (wood, scrap metal, plastic,
fencing, etc.) that could be projected by the machine or damage it.
The chain curtains or rubber flaps help to avoid accidental projections: if they are damaged, they have to
replaced immediately

12
Bale Unroller - Spreader
Groupe Anderson
11. LOADING A BALE
In order to facilitate the machine’s transport, a flat iron arm connects the frame and the loading arm. It is
imperative to remove this fixation before use (see sketch below).
It is imperative to position the bale in the right direction for unrolling: if you load in reverse gear,
position the bale in such a way that the spiral goes clockwise when you are looking at it while sitting on
the tractor seat (see sticker on the bale unroller).
Open the loading arm, then put it onto the ground.
Depending on the used bales:
a) if you use wrapped bales, withdraw the plastic before loading.
b) if you use straw or hay bales, load before cutting the strings.
c) if you use fillet straw bales, load the bale on the arm, incline the arm when half-way loaded,
cut the fillet on the machine side and return the latter on the arm.
Please scrupulously respect the following instructions:
Never lower the loading arm while the bale unroller is on the ground
The bale unroller’s underside has to be at 40 cm from the ground.
13
Bale Unroller - Spreader
Groupe Anderson
Correctly center the bale with respect to the loading arm before moving off
to avoid causing damage to the latter
Position the bale right to the stop
Never take the bale when the bottom of the machine is too high above the
ground
Never use the loading arm’s glide rail for bringing back the bale
14
Bale Unroller - Spreader
Groupe Anderson
In case of wrapped bales, do not use the loading arm to unload bales
The loading arm is exclusively suited for loading bales and should in no way serve as a handling
arm.
The arm should not meet obstacles during the bale unroller’s displacement. It also should not
meet obstacles during its lifting up or going down as well as during opening or closing of its
extension.
12. USE
12.1 Using the bale unroller on a tractor
The machine is intended for being used by only one person. It is the responsibility of the user to ensure
that nobody is in the vicinity of the machine when starting it up, that safety distances are respected.
Do not use your machine for another type of work than the work the machine is provided for.
The starting up of the unrolling device has to be made:
a) If directly plugged in tractor’s connections, the pressure will be obtained by acting upon the
tractor control.
b) If plugged in an auxiliary spool valve, lock the tractor control in order to evacuate the pressure
towards the spool valve; starting up of the unrolling device will be effected by the control spool
valve.
In case of deformed bales (for example flattened on one side) equalization can be obtained after one or
several forward / reverse manoeuvers.
Depending on the model, unrolling can be performed to the right, to the left or backwards, to do so, you
just have to turn the bale unroller into the chosen position and to lock it.
If the machine is equipped with a bedding device, avoid any violent contact between the bale and the
bedding device.
If the bale has been realised in a machine with a fixed chamber, the unrolling operation at the end of the
bale will necessitate more forward / reverse feedstuff evacuation manoeuvres.
On the mobile machines, in case of deformed bales, it is advisable to position the bale unroller in the
position for unrolling backwards and to incline the machine towards the top in order to facilitate its rotation.
Unroll and make it do a quarter turn, bring it back to the initial position and repeat until normal unrolling is
achieved.
15
Bale Unroller - Spreader
Groupe Anderson
To avoid an abundant material influx on the bale unrollers-spreaders, an adjustment of bedding system
allows the regulation of the unrolling device.
Before acting upon the hydraulic orientation, you have to make sure that no obstacle can obstruct
its movement.
Hydraulic orientation has to be made in a flexible manner to avoid an important shock when reaching the
stop.
Before acting upon the hydraulic offset, you have to make sure that no obstacle can obstruct its
displacement.
Hydraulic offset has to be made in a flexible manner to avoid an important shock when reaching the stop.
The loading arm is exclusively intended for loading bales and not for handling them.
The bale only has to be tightened by the hydraulic arm extension once it is completely engaged in the
loading arm.
To load a bale of more than 750 kg (respecting the maximum authorized weight of 1000 kg), it is
necessary to horizontally position the arm and not lowered to a maximum.
Check tyre pressure, it has to be 6 bar.
Do not change in direction abruptly, give time to the wheels’ pivoting.
Pay attention during a such manoeuver of changing in direction, the chassis may move to the right or to
the left just at the moment when the wheels are pivoting in order to take the direction of travel.
For displacements on public roads, you have to lift up the bale unroller.
12.2 Stopping the machine
For stopping the unrolling device, the bedding system and the other hydraulically driven elements, you
have to stop the tractors’ control spool valves. Do not approach the machine while elements are rotating.
