2. Designed purpose of use
The AVANT Jib boom is an attachment that is intended to be used with AVANT compact loaders that are
listed in Table 1. The attachment is intended for moving and lifting of loads with the loader, and it offers good
visibility to the load. The Jib boom can be used to lift objects to places out of reach or at high levels
effortlessly, controllably, and safely. The attachment is especially useful when moving objects that are not
meant to be lifted with pallet forks. The Safe working load of the Jib boom is 500 kg. The boom is not intended
to handle loads that are heavier than this. However, the actual operating capacity of the jib boom depends on
the loader model, and various environmental factors, as shown in this manual. Refer to the operator's manual
of your loader for information about the lift capacity of your loader. In this manual are load charts that apply for
loaders that are manufactured in 2018 or later.
The fixed jib boom is equipped with a rotating lifting hook that has a safety latch. The lifting point is located at
the end of the boom, at 1200 mm from the attachment coupling plate. Always make sure that the lifting point
on the load, all lift accessories, and the jib boom are in good condition.
The Jib boom 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 dropping of load - Never exceed the Safe Working Load of the
attachment. The Safe Working Load of the Jib boom itself is 500 kg. Never
exceed this load. The maximum load that can be lifted with a loader, the Rated
Operating Capacity, depends on several factors, such as the following:
the loader model
position and extension of the loader boom
position of the articulated loader frame
counterweights on the loader
movements of the loader, its boom, and load
smoothness of the ground surface and any inclination
Always follow the operator's manual of the loader to determine the Rated
Operated Capacity of each loader model. See more information on page 18.
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 load, the
loader boom or the attachment.
The stability of the loader may change when
leaving the driver’s seat, leading to tipping over of the machine. Always remember
that t
he 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
loader is not intended to be left to keep a load elevated for longer periods. Lower the
att
achment firmly on the ground before leaving the driver's seat and never allow
anyone to be under the boom or attachment.

8 (32)
WARNING
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 collision - Keep a safe distance to other people and obstacles in the
operating environment.
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.
Keep the loader articulation in straight position when handling heavy loads. When
turning the articulation, the loader may tilt forward.
Use only type approved lifting accessories, such as chains or straps, that are suitable
for lifting work.
Observe maximum load indicated in the operator’s manual of the loader. Be
especially careful when the load se
nsor 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.
Drive carefully with lifted load as the swinging of the load may affect the stability of
the loader. Keep others away from under the boom or the area where the swinging of
the load creates an impact or crushing hazard.
Make sure that overhead clearance is sufficient. Hitting an overhead obstacle may
cause the loader to t
ip over. Keep a safe distance from electric cables, lamps, or
other electric systems; hitting live parts may cause electric shock.
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 equipment 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.

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 coupling plate on the loader boom and the counterpart on the
attachment.
If the attachment is not locked to the loader, it may fall from the loader and cause a hazardous situation.
Never drive with the loader and never lift the loader boom if the attachment has not been fully locked. To
prevent hazardous situations, always follow the coupling procedure shown below. Also remember the safety
instructions shown in this manual.
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 locking pins of the quick coupling pl
ate of the loader 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 system, see
additional instructions about the use of the locking system from the operator's
manual of the loader.

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 the upper pins of the loader’s quick coupling plate so that they are under
the corresponding brackets of the attachment.
Step 3:

WARNING
Risk of crushing - Avoid tipping over the attachment.
Excessive tilting or lifting of an
unlo
cked 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 do 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 the
attachment, make sure that the locking pins ar
e 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 of the attachment, and compatibility of loader cont
rol 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 tipping 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 6, ask your Avant dealer before using this attachment.

15 (32)
6. Operating the attachment
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 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 lif
ting 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
. ..
WARNING
Risk of crushing -
Never allow anyone to get under a
lifted attachment or loader boom. Keep in mind
that the
loader boom 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.
. ..
WARNING
Risk of falling from height and crushing under an
attachment or loader -
Never use the attachment as a
lifting platform or to carry people.
Never use the loader or
its attachments to lift persons or as any kind of work platform
even temporarily. Never climb on the attachment.
Always lower the attachment on the ground before leaving
the driver's seat. The loader is not intended to hold loads
lifted for longer periods of time.
. ..

6.1 Checks before use
Use only when all pins are locked and secured in place.
Check the general condition of the attachment and the loader.
Check that the lifting hook is intact and that its safety latch is in good condition. Do not use damaged
equipment.
Use only lifting equipment that are type approved for lifting and strong enough for the task. The lifting
rope should have a rated capacity of at least twice the load. Normal load securing straps are usually
not approved for lifting work.
Do not tie the lifting ropes. Use suitable hooks or links.
Plan the lifting work ahead, avoid hanging the load unnecessarily.
Ensure that the ground surface is level and solid enough for safe lifting.
Drive carefully on uneven terrain and note the effect of heavy load at the front of the loader to the
stability and handling of the loader.
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.
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
to operate the equipment.
Remember correct working methods and avoid leaving the driver's seat unnecessarily. Practise the
use of the attachment and the controls of the loader in a safe area. If you are unfamiliar with the
particular loader model, it is recommended to practise its use without any attachments.
6.2 Operator qualification
Anyone who intends to use the attachment must:
Know the intended use of the attachment.
Know how to use the loader safely in different operating conditions.
Read and always follow the instructions concerning the use of the attachment in this operator's
manual.
Have this manual and the operator's manual of the loader available.
Ensure that the loader and the attachment are used in a safe manner and as intended.
Never allow children to operate the equipment.
Never operate the loader or attachments while under the influence of alcohol, drugs, medication that
may impair judgement or cause drowsiness, or if not otherwise medically fit to operate the equipment.
Complete any possible mandatory training required by the employer before use.
Have valid driver's license when operating the equipment on road areas when required by law.
. ..

17 (32)
6.3 Operation
The Safe Working Load limit for the attachment is 500 kg. Never handle loads that are heavier than 500 kg.
The jib boom can get damaged as a result, and the load may fall.
The maximum load that can be safely lifted with a loader depends on the load handling capacity of the loader.
See Rated operating capacity on page 18 in this manual, and the operator's manual of the loader for more
information.
6.3.1 Transporting objects
When using the Jib boom for transporting objects, make sure that the load is well balanced and that it will not
move when lifting the load from its lifting point. All loads must be transported calmly with smooth movements,
and as low and close to the loader as possible, as shown in the figure below. For the best stability of the
loader, keep the telescopic boom of the loader fully retracted, and extend only when necessary.
Swinging of the load must be avoided. Use type approved load securing chains or straps as necessary.
WARNING
Risk of collision - Ensure good visibility. Ne
ver lift this attachment to a position where
visibility from the driver's position is obstructed. Ensure unobstructed visibility to all
directions.

18 (32)
WARNING
Risk of tipping over - Avoid overload and keep heavy load close to the loader. Keep
load 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.
If the loader is not equipped with the boom self levelling:
WARNING
Prevent material from falling on you -
Monitor the position of the attachment during
lifting.
When lifting material, the attachment must be simultaneously tilted to prevent the
load from falling from the attachment on the loader or the operato
r. Fitting the loader with
the boom self levelling option makes repeated loading work easier.
6.4 Rated Operating Capacity
Always follow the operator's manual of the loader to determine the Rated Operating Capacity of each loader
model. A load diagram is presented in the operator's manual of each loader model. With the diagram, the load
handling capacity of the loader can be evaluated according to the distance of the load hook from the loader.
The hook of the Jib boom is at 1200 mm front from the quick coupling plate of a loader.
The Rated Operating Capacity applies, when
the standard counterweights of the loader are installed
adding or removing counterweights can change the rated operating capacity significantly
the loader is operated on smooth and calm manner
abrupt movements of the loader or its boom can cause the loader to tip over
swinging of the load can cause the loader to tip over
the ground surface is firm, level, and smooth
recommended tyre pressures are followed.
Always remember that the actual load carrying capacity varies according to operating conditions. Especially
inclines and unevenness of the surface of operating area has a great effect. The indicated values apply only
on level, smooth surfaces. Be especially careful when the load sensor indicator is activated, if your loader is
fitted with a load sensor system.
How to read the load charts in this manual:
This manual shows the Rated Operating Capacity for loaders that are manufactured during or after 2018. It
also applies to other loader models, as long as their axle weight and principal dimensions are the same.
The Rated Operating Capacity depends on the horizontal distance of the load from the front axle of the loader.
The load charts show the values in the extreme positions of the telescopic boom, and in two positions
between the extremes:
1. Telescopic boom of the loader is in fully retracted position
2. Telescopic boom of the loader is extended about 1/4
3. Telescopic boom of the loader is extended about 3/4
4. Telescopic boom of the loader is in fully extended position
The load charts in this manual show the Rated Operating Capacity, which is defined as 50 % of the tipping
load of the loader at each position.

19 (32)
The load chart drawings are illustrations of approximate reach distances and reach
height
. The load charts provide an estimation of distances to help to determine rated
operating capacities, they are not precision drawings of distances.
WARNING
Risk of dropping of load - Never exceed the Safe Working Load of the
attachment. The Safe Working Load of the Jib boom itself is 500 kg. Never
exceed this load. The maximum load that can be lifted with a loader, the Rated
Operating Capacity, depends on several factors, such as the following:
the loader model
position and extension of the loader boom
position of the articulated loader frame
counterweights on the loader
movements of the loader, its boom, and load
smoothness of the ground surface and any inclination
Always follow the operator's manual of the loader to determine the Rated Operated
Capacity of each loader model. See more information on page 18.
DANGER
Risk of tipping over - Do not drag heavy loads from e.g. shelf.
Do not reverse with
the loader while simultaneously dragging load. Make sure that the loader can
handle the
load being lifted. When lifting load from a high level, the loader could tip forward when
reversing with the loader.
