2. Designed purpose of use
The AVANT Log grab is an attachment suitable for use with AVANT compact loaders shown in Table 1. The
Log grab is intended to be used only when attached as instructed to Avant pallet forks A21047, A21039 or
A36589. With the pallet forks that have a log grab mounted onto them you can lift and transport single logs,
smaller timber bundle, or fence posts. The log grab is also suitable for lifting and moving tree branches or
piles of brushwood.
The Log grab is equipped with a powerful hydraulic cylinder and can therefore also be used to lift bigger
stones or rocks. Handling of pallets is possible even if the log grab is attached to the pallet forks, but the
grapple limits the height of the pallet.
The Log 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 technicians. 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 dealer 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 proc
edure, 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 designe
d 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 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
unexpected
ly due to loss of stability, mechanical fault, or if another person operates
the controls of the loader, leading to crushing 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.
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 com
pletely retracted, to keep the centre of gravity
low.
Follow the safety instructions laid out in the operator’s manual of the pallet forks.
Do not connect any lifting equipment to the log grab.
Never leave the equipment unattended if the grapple or the pallet forks are raised.
Keep the loader articulation in straight position when handling heavy loads. When
turning the articulation, the loader may tilt forward.

WARNING
Observe maximum load indicated in the operator’s manual of the loader. Be
especial
ly careful when the load sensor indicator is activated, if your 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.
Tipping over - Crushing hazard - Do not try to move an unattached attachment by
pushing or dragging it, instead, always handle it with the loader.
Ensure that an unattached attachment is supported properly and can't accidentally
move or tip over.
Pay attention to the surroundings and any other persons and machines moving in the
vicinity. Other persons must keep safety distance of 5 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.
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.
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 attachmen
t 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, mechanical faul
t 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
shut down (cru
shing 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.

3.1 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 exposure 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.
. ..
3.2 Safe shutdown procedure
Safe position of the attachment, before going near the loader boom:
WARNING
Always set the attachment to a safe position before going near the attachment.
Safe position will prevent unintentional movements of the attachment and the loader
boom. Note that the attachment can move even if the engine of the loader is turned off.
Safe stopping procedure:
Lower the boom completely down and lower the attachment flat on the ground.
Shut down the loader engine and lock the parking brake.
Prevent starting of the machine, remove ignition key.
