2. Designed purpose of use
The AVANT XL Silage grabs are attachments that are suitable for use with AVANT multi purpose loaders that
are shown in Table 1. The main function of the silage grabs is to move or distribute silage or similar loose
materials. Two removable tines are fitted to the both sides of the grabs for better grip of loose material. All of
the XL silage grabs’ tines are replaceable.
The XL Silage grab series is available in three different widths to match with different loader models. Open
grab construction on the top offers good visibility when the grab is open. The strong heavy-duty construction is
equipped with two hydraulic cylinders providing enough compression force to handle large amounts of
material.
The XL Silage grab is not designed for any other use than what is specified in this manual and must not be
used for any other purposes than what is intended for.
The attachment has been designed to require as little maintenance as possible. The operator can perform
regular maintenance tasks. All repair work can’t be performed by the operator, and demanding repair and
maintenance operations are to be left for professional maintenance. All maintenance work must be done using
proper safety equipment. Spare parts must be identical with original specifications, which can be ensured by
using only original spare parts. A separate spare parts catalogue may be available, consult your Avant dealer.
Familiarise yourself with the manual's instructions regarding service and maintenance. Please contact your

3. Safety instructions for using the attachment
Please bear in mind that safety is the result of several factors. The loader-attachment combination is highly
powerful and improper or careless use or maintenance may cause serious personal injury or property
damage. Due to this, all operators must carefully familiarise themselves about correct use and the operator's
manuals of both the loader and the attachment before starting operation. Do not use the attachment if you
have not completely familiarised yourself with its operation and the related hazards.
DANGER
Misuse, careless use, or using an attachment that is in poor condition may
cause risk of serious injuries. Familiarise yourself with the
controls of the loader,
correct coupling procedure, and the correct way to operate the attachment at a safe
area. Study especially how to stop the equipment in a safe manner. Read all safety
precautions carefully.
Read all safety instructions carefully before handling the attachment
WARNING
When attaching an attachment to the loader, ensure that the locking pins of the
loader's quick attach plate are in the lower position and that they have locked
the attachment to the loader. Never lift or move an unlocked attachment.

This attachment is designed to be used by one operator at a time. Do not let others
near the danger area of the equipment when it is in use.

Always transport the attachment as low as possible to keep the centre of gravity low,
and keep the telescopic boom retracted during driving.
Risk of getting injured by sharp tines of grapple - Lower the grapple completely
before going near the sharp tines and the grapple, which may lower even if the
loader is not running. Lower the attachment on t
he ground and lower its grapple
completely before leaving the driver's seat to avoid unintentional movements of the
loader and the grapple. Follow safe stopping procedure.
Sudden movements can cause the loader to tip over - Operate the controls of
the loader in a slow and calm manner.
Be careful when lifting load to high level or
lifting load from high. Avoid sudden changes in speed or direction to maintain
balance of the loader especially when handling heavy loads. Drive slowly and
carefully especially on inclined terrain or slippery surfaces.
Risk of tipping over - Keep loads close to ground while driving. Carrying heavy
loads can shift the centre of gravity of the loader and lead to tipping over of the
loader. For the best stability always transport
loads as low and close to the loader as
possible, with the telescopic boom completely retracted, to keep the centre of gravity
low.
Risk of crushing - Never go or allow anyone else to go under the loader boom
or attachment. The stability of the loader
may change when leaving the driver’s seat,
leading to tipping over of the machine. Always remember that the boom may lower
unexpectedly due to loss of stability, mechanical fault, or if another person operates
the controls of the loader, leading to crushin
g hazard. The loader is not intended to
be left to keep a load elevated for longer periods. Lower the attachment firmly on the
ground before leaving the driver's seat and never allow anyone to be under the boom
or attachment.
Keep the loader articulation in straight position when handling heavy loads. When
turning the articulation, the loader may tilt forward.

7 (24)
WARNING
Observe maximum load indicated in the operator’s manual of the loader. Be
especially careful when the load sensor indicator is activated, if yo
ur loader is fitted
with a load sensor system.
Make sure that the surface can bear the total load. Also follow the correct tyre
pressure settings.
Pay attention to the surroundings and any other persons and machines moving in the
vicinity. Other pers
ons must keep safety distance of 2 meters. Pay attention to the
contours of the terrain and other hazards, such as branches and trees that can reach
to the driver's area, loose rocks, and slippery surfaces.
Make sure that overhead clearance is sufficient. Hitting an overhead obstacle may
cause the loader to tip over. Keep a safe distance from electric cables, lamps, or
other electric systems; hitting live parts may cause electric shock.
Ensure that ventilation is sufficient when operating indoors. Do not operate the loader
in closed spaces regardless of the engine or fuel type. Exhaust gases may
concentrate to hazardous levels.
Never use the attachment to lift or to transport persons or as any kind of work
platform even temporarily.
Make sure to use only an attachment that is in good condition. Check the attachment
thoroughly in regular intervals. Do not modify the attachment in a manner that would
affect its safety. It is prohibited to drill holes on the attachment, and welding or other
means of fixing hooks or other objects on the attachment is strictly prohibited.
Shut down the loader and place the attachment to a safe position as shown in Safe
stopping procedure before any cleaning, maintenance, or adjustments.
Use the attachment only for its intended purpose. Other use may create unnecessary
safety risks, and the equipment may get damaged.
Make sure that the loader is equipped with necessary safety components, and that
they are in working condition. Seat belt must be used. If there are
specific hazards
related to the operating area, use appropriate safety equipment.
Also read the safety instructions and correct use of the loader from the operator's
manual of the loader.
DANGER
Risk of crushing - Going under the loader boom or an
attachment can cause serious injury or death.
Never go
under the loader boom and prevent others from getting near
lifted boom or attachment. Going under a raised attachment
or loader boom is dangerous, as the boom may lower due to
loss of stability, mech
anical fault or when other person
operates the controls of the loader. Lower the attachment
firmly on the ground to a safe position before leaving the
driver’s seat.
Keep in mind that the loader boom can be lowered or tilted
even if the engine has been shu
t down (crushing hazard).
The loader is not intended to be left to keep a load elevated
for longer periods. Always lower the attachment to a safe
position before leaving the driver's seat.

5. Attaching the attachment
Attaching the attachment to the loader is quick and easy, but it must be done carefully. The attachment is
mounted to the loader boom by using the quick attach plate on the loader boom and the counterpart on the
attachment.
If the attachment is not locked to the loader, it may detach from the loader and cause a hazardous situation.
The loader must not be driven and the boom must never be lifted when the attachment has not been locked.
To prevent hazardous situations, always follow the coupling procedure shown below. Also remember the
safety instructions shown in this manual. The attachment is mounted to the loader as follows:
WARNING
Crushing risk - Make sure that an unlocked attachment will not move or fall over.
Do not stay in the area between the attachment and the loader. Mount the attachment
only on level surface.
Never move or lift an attachment that has not been locked.
Avant quick coupling system:
Step 1:

Lift the quick attach plate locking pins up and turn them backwards into the slot
so that they are locked in the upper position.
If your loader is equipped with a hydraulic attachment locking sy
stem, see
additional instructions about the use of the locking system from the relevant
manuals.

Make sure that the hydraulic hoses are positioned so that they will not get in
between the coupling plate of the loader and the attachment, and that they will
not get squeezed or chafed against sharp edges.
Step 2:
Turn the quick attach plate hydraulically to an obliquely forward position.

Drive the loader onto the attachment. If your loader is equipped with a
telescopic boom, you can utilise this.
Align t
he upper pins of the loader’s quick coupling plate so that they are under
the corresponding brackets of the attachment.
Step 3:
Lift the boom slightly –
pull the boom control lever backward to raise the
attachment off the ground.
Turn the boom contro
l lever left to turn the bottom section of the quick attach
plate onto the attachment.
Lock the locking pins manually or lock the hydraulic locking.
Always check the locking of both locking pins.

12 (24)
WARNING
Risk of crushing - Avoid tipping over the attachment.
Excessive tilting or lifting of an
unlocked attachment increases the risk of tipping the attachment over. Do not use the
automatic locking of the locking pins when the attachment is lifted more than one meter
from the ground. If the locking pins d
o not return to the normal position when tilting, do
not tilt or raise the attachment any more. Lower the attachment on the ground and
secure the locking manually.
WARNING
Risk of falling objects -
Prevent dropping of
attachment.
An attachment that
has not been completely locked to the
loader may fall on the boom or towards the operator, or
fall under the loader during driving, causing loss of
control of the loader. Never move or lift an attachment
that has not been locked. Before moving or lifting t
he
attachment, make sure that the locking pins are in the
lower position and come through the fasteners on the
attachment on both sides.
WARNING
Make sure the loader is compatible with the attachment.
Stability of the loader,
possible overload o
f the attachment, and compatibility of loader control systems must be
ensured in addition to mechanical compatibility of the attachment. If you use the
attachment with a loader that is not fit to be used with the attachment model you have,
risks include ti
pping over, damage to attachment due to overload, and risks related to
uncontrolled motion of attachment and its parts. If your loader is not listed in Table 1 on
page 5, ask your Avant dealer before using this attachment.
5.1 Connecting and disconnecting hydraulic hoses
On Avant loaders the hydraulic hoses are connected using the multi connector system. If you have an Avant
300-700 series loader with the conventional quick couplers and wish to change to the multi connector system,
contact your Avant dealer or service point for instructions or installation services.
WARNING
Risk of movement of the attachment and ejection of hydraulic oil -
Never connect
or disconnect quick couplings or other hydraulic components while the control
l
ever of the auxiliary hydraulics control lever is locked on or if the system is
pressurized.
Connecting or disconnecting the hydraulic couplings while the system is
pressurized may lead to unintended movements of the attachment, or ejection of high-
pressur
e fluid, which can cause serious injuries or burns. Follow safe stopping procedure
before disconnecting hydraulics.

13 (24)
Keep all fittings as clean as possible; use the protective caps on both the attachment and
the loader. Dirt, ice, etc. may make using
the fittings significantly more difficult. Never
leave the hoses hanging on the ground; place the couplings onto the holder on the
attachment.
Connecting the multiconnector system:
1.
Align the pins of the attachment connector with corresponding
holes
of the loader connector. The multiconnector will not connect
if the attachment connector is upside down.
2.
Connect and lock the multiconnector by turning the lever towards
the loader.
The lever should move easily all the way to its locking position. If the lever does not slide smoothly, check the
alignment and position of the connector and clean the connectors. Also shut down the loader and release the
residual hydraulic pressure.
To disconnect the multiconnector system:
Before disconnecting put the a
ttachment down on a solid and even
surface.
1. Switch off the auxiliary hydraulics of the loader.
2.
While pushing unlock button, turn the lever to disconnect the
connector.
3.
After ending operation put the multiconnector on its holder on the
attachment.
Disconnecting hydraulic hoses:
Before disconnecting the fittings, lower the attachment to safe position on solid and level surface. Turn the
control lever of the auxiliary hydraulics to its neutral position.
When uncoupling the attachment, always disconnect
the hydraulic couplings before
unlocking the quick coupling plate, to prevent hose damage and any oil spills. Reinstall
the protective caps on the fittings to prevent impurities from entering the hydraulic
system.
Releasing residual hydraulic pressure:
In case residual pressure is left in the hydraulic system of the attachment, it is often possible to disconnect the
hydraulic couplings, but it may be difficult to connect them the next time. If the fittings will not connect, the
residual pressure must be released by turning the auxiliary hydraulics control lever of the loader, when the
engine is turned off. To make sure that there will not be residual pressure in the hydraulic system of the
attachment, shut down the loader engine and move the auxiliary hydraulics control lever of the loader back
and forth before disconnecting the couplings.

6. Instructions for use
Check the attachment and the operating environment once more before starting to work, and that all obstacles
have been removed from the operating area. Quick inspection of the equipment and the operating area before
use are parts of ensuring safety and the best performance of the equipment.
WARNING
Risk of tipping over - Avoid overload.
Loader can tip over
when handling too heavy loads, or becau
se of dynamic
movements caused by driving with and handling of a heavy
load. Do not extend the telescopic boom when the load
approaches the lifting capacity of the loader, or when the
loader boom is in horizontal position. When you notice that
the rear whe
els of the loader are about to lift from the ground,
or if the load indicator of the loader (if fitted) signals:
Lower the load calmly and retract the telescopic boom
Avoid sudden changes in speed or direction whenever load is lifted
Use additional counterweights as needed
. ..
WARNING
Risk of falling from height and crushing under bucket or
loader -
Never use a bucket as a lifting platform or to
carry people.
Never use the loader or its attachments to lift
persons or as any kind of work platfo
rm even temporarily.
Never climb on the attachment.
Always lower the bucket on the ground before leaving the
driver's seat. The loader is not intended to hold loads lifted for
longer periods of time.
. ..
WARNING
Risk of crushing - The sharp ti
nes of the attachment and
its grapple can cause serious injuries.
Make sure that
there are no other persons at the operating area and keep a
safe distance to persons or farm animals. Lower the grapple
before driving with the loader. Stop the loader followi
ng the
safe stopping procedure before going near the attachment.

15 (24)
.
6.1 Checks before use
Check the operation of the grapple before each work shift. Check that hydraulic hoses will not get
chafed, and that the grapple joints are lubricated.
Ensure that bystanders are at a safe distance when operating the equipment. Do not let anyone to
enter danger area of the boom or to stay directly in front of the loader. Also make sure that it is safe to
reverse with the loader. Never assume that bystanders will remain where you last saw them;
especially children are often attracted to the moving equipment.
Check the general condition of the attachment and the loader, and check for possible hydraulic oil
leaks. The attachment must not be used, if there is a fault in the hydraulic system of the loader or the
attachment. Refer to Chapter 7 for maintenance instructions.
Operate the attachment and the controls of the loader only when seated on the driver’s seat. Ensure
that the loader and the attachment are used in a safe manner and as intended. Do not allow children

6.2 Operating the XL silage grab
WARNING
Risk of serious personal injuries -
Ensure that there are no other persons near the
operating area. Do not
allow others closer than 2 metres form the grab, to the boom
danger area, or directly in front or back of the loader. Move carefully and calmly near
persons or farm animals. Also make sure that it is safe to reverse with the loader.
Keep the material
being transported as
close to the loader and as low as possible.
When transporting silage or other loose
material with the XL silage grab, ensure,
that the load is secured on the grab.
Before using the Grapple bucket for the first time, check that
the hydraulic hoses are
positioned so, that you can move the loader boom and the grapple to all positions.
To avoid damage of the hydraulic hoses and to avoid oil spill, the hoses must not
get pinned or stretched in any position of the attachment or the loader boom.

17 (24)
Controlling the grapple
Move the auxiliary
hydraulics control lever
towards its locking
position (or use the
electric buttons of the
optional electric joystick)
to lower the grapple.
The lever should not be
left to the locking
position.
Move the lever away
from the locking position
to lift the grapple.

18 (24)
.
If the loader is not equipped with the boom self levelling:
WARNING
Prevent material from falling on you - Monitor the position of the bucket.
When
lifting mater
ial to a high level, the quick coupling plate must be simultaneously tilted to
prevent the load from falling from on the loader or the operator. Fitting the loader with the
boom self levelling option makes repeated loading work easier.
WARNING
Avoid sudden loss of stability - Never drag loads from e.g. a shelf.
If the load that
you want to lift from height is too heavy, the loader can tip forward when reversing with
the loader. Never reverse and drag with the loader before making sure that the loader
can handle the load that is being lifted.
6.3 Material handling
Use maximum load indicated in the diagram of the operator’s manual of the loader as a guideline. Remember
that the actual load carrying capacity varies according to operating conditions, especially unevenness of
operating area has a great effect. Be especially careful when the load sensor indicator is activated. Also,
make sure that the ground surface is firm and follow recommended tire pressures.
WARNING
Risk of tipping over - Avoid overl
oad and keep heavy load close to the loader. Keep
loads close to the ground whenever driving, especially during turns and uneven
terrain.
Pay attention that a heavy load or long distance between the loader and the
centre of gravity of the load will affect
the balance and handling of the loader. The use of
additional counterweights is recommended especially when operating smaller loader
models. With heavy loads, the telescopic boom must be kept retracted while moving with
the loader. Always wear seat belt.
6.4 Working on uneven ground
Extra caution is needed when using the equipment on inclined terrains and slopes. Drive slowly especially on
inclined, uneven, or slippery surfaces, and avoid sudden changes in speed or direction. Operate the controls
of the loader with careful and smooth movements. Watch out for ditches, holes on the ground, and other
obstacles, as hitting an obstacle may cause the loader to tip over.
Maximum lifting capacity can not be achieved on inclined terrain. On horizontally tilted terrain the load must
not be lifted high. The loader frame articulation should be kept straight when lifting heavy loads; turning the
load during lifting operation will affect the stability of the loader and may lead to overturning of the machine.
6.4.1 Operating with a tilt adapter
When you work on slightly inclined terrains, a tilt adapter is an useful option. The tilt adapter is fitted in
between the attachment and the quick coupling plate of the loader. The adapter allows the attachment to be
tilted sideways. The possible tilt adapter options at the time of print of this manual are ±12.5º (model A34148)
or ±360º (model A424406). Read the instructions provided with the tilt adapter and in the operator's manual of
the loader. More information about the tilt adapters is available from your AVANT retailer or from the AVANT
web pages at www.avanttecno.com.

19 (24)
.
6.5 Transport position
CAUTION
Keep the loader stable. Always
transport the silage grab as low and
close to the ground as possible.
Keep the telescopic boom retra
cted
and grapple completely lowered
during drive.
6.6 Storing the attachment
Uncouple and store the attachment on level ground. The best way to store the attachment is a place where it
is protected from direct sunlight, rain, and extreme temperatures.
Avoid leaving the attachment laying directly on the ground. Place it on blocks of wood or on a pallet, for
example.
Place the multiconnector on to its holder as indicated with an arrow in the figure below. Never leave the
hydraulic connector on the ground.
Make sure that the attachment is secured against all movements during storage.
Never climb on the attachment.
For longer storage periods touch up the paint where needed, grease the lubrication points and oil the visible
parts of the hydraulic cylinder shafts to prevent rust damage.

20 (24)
7. Maintenance and Service
The attachment has been designed to be as maintenance free as possible. Continuous maintenance includes
regular cleaning and lubrication, and monitoring the condition of the attachment. Because of the crushing
hazard caused by lowering machine parts, all maintenance work must be done when moving parts have been
lowered down completely and the attachment is lowered flat against the ground.
DANGER
Risk of crushing - Never go under lifted attachment. M
ake sure the attachment is
properly supported during all maintenance work. Never go under a lifted attachment. The
loader boom may lower unexpectedly during maintenance causing serious injuries from
crushing or impact even when the loader engine is not run
ning. All maintenance and
service must be performed when the attachment has been lowered down to a safe
position.
WARNING
Risk of crushing -
The grapple may lower by itself as
a result of a fault or use or service mistake causing
serious injuries.
All maintenance procedures must be
performed when the grapple has been lowered down
completely.
7.1 Inspection of hydraulic components
Check the condition of the hydraulic hoses and components when the engine has been turned off, system has
cooled down, and the pressure has been relieved. Do not use the equipment, if you have discovered a leak in
the hydraulic system of the attachment or the loader. Leaking hydraulic fluid may penetrate skin and cause
serious injuries. Seek medical attention immediately in case hydraulic fluid penetrates the skin. Wash any part
of body that has been in contact with hydraulic oil carefully with water and soap. Hydraulic fluid is also harmful
to the environment and any leak to the environment must be prevented. Repair all leaks immediately after
detecting them; a small leak can quickly grow into a big one. Operate the attachment only with type of
hydraulic oil that is accepted for use in Avant loaders.
DANGER
Risk of high pressure fluid injection
through skin - Release re
sidual pressure
before maintenance.
Never handle hydraulic
components when the hydraulic system is
pressurised, since a fitting may break or
become loose and the released oil may cause
serious injuries. Do not use the equipment, if
you have discovered a fa
ult in the hydraulic
system.
