2. Designed purpose of use
The AVANT grabbing tool is an attachment that is designed and manufactured to be used with AVANT multi-
purpose loaders shown in Table 1. The grabbing tool is an ideal attachment for lifting and handling of round
objects. It is especially suited for lifting of barrels, plant and tree pots and other objects, than can be grabbed.
The grabbing force of the tool can be adjusted, which means all kinds of objects can be handled without
damaging them. Grabbing tool is equipped with two smaller, rubber-padded grabs, which allows the handling
of smaller and more fragile objects. When the grab is opened completely, it can take larger objects like
barrels, bigger plant pots etc.
The grabbing tool is not designed for any other use than specified and must not be used for any other
purposes than intended.
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
AVANT retailer if you have additional questions about the operation or maintenance of the equipment, or if
you require spare parts or maintenance services.

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 procedu
re, 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.
The Grabbing tool 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.
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.
Carrying heavy loads can shift the centre of gravity of the loader and lead to tipping
over of the loader. Always transport the load as low and close to the machine as
possible wi
th the telescopic boom completely retracted to keep the centre of gravity
low and for the best stability.
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 crushing hazard. The attachment or the loader
are not intended to be left to keep a load elevated for longer periods. Lower the
attachment before leaving the driver's seat.
Keep the loader articulation in straight position when handling heavy loads. When
turning the articulation, the loader may tilt forward.
Observe maximum load indicated in the operator’s manual of the loader. Be
especially careful when the load sensor indicator is activated.
Make sure that the surface can bear the total load. Also follow the correct tyre
pressure settings.

WARNING
Pay attention to the surroundings and any other persons and machines mo
ving in the
vicinity. 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.
Adjust the grabbing force to suit the object being handled only when the loader
engin
e has been shut down and the residual pressure has been released. Do not
adjust the grabbing force while holding a load.
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.
WARNING
Risk of crushing -
Never allow anyone to get under a
lifted attachment or loader boom.
Keep in mind that the
loader b
oom can be lowered or tilted even if the engine has
been shut 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.

9 (26)
WARNING
Risk of tipping over - Avoid overload.
Loader can tip over
when handling too heavy loads, or because 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 wheels 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
3.1 Safe shutdown procedure
Safe stopping of the attachment, before going near the attachment:
WARNING
Always stop the atta
chment following safe stopping procedure before leaving
the driver's seat.
Safe stopping procedure prevents all unintentional movements of
the attachment. Note that the loader boom can move down even if the engine of the
loader is turned off. Safe stopping procedure:
Lower the boom and the attachment on the ground.
Shut down the loader engine and lock the parking brake.

Release residual pressure from the hydraulic system; move all hydraulic control
levers to their extreme positions a couple of times.
Prevent starting of the machine, remove ignition key.
3.2 Personal protective equipment
Remember to wear proper personal protective equipment:

The noise level at the driver's seat may exceed 85 dB(A) depending on loader
model and operating cycle. Extended expo
sure to loud noise can cause
hearing impairment. Wear hearing protection while working with the loader.
Wear protective gloves.
Wear safety boots whenever working with the loader.
Wear safety glasses when handling hydraulic components.
