2. Designed purpose of use
The AVANT Telescopic jib boom is an attachment is intended to be used with AVANT multi purpose loaders
that are listed in Table 1. The attachment is especially useful when moving objects that are not meant to be
lifted with pallet forks. The attachment is intended for moving and lifting of loads with the loader, and it offers
good visibility to the load. The stepless telescopic extension of the jib boom makes it possible to reach places
that would be otherwise hard to reach.
The Safe working load of the Telescopic Jib boom is 800 kg. The boom is not intended to handle loads that
are heavier than this. However, the actual operating capacity of the telescopic 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 telescopic boom of the jib boom works as an additional extension to the boom of the loader. It offers
greater reach and lifting height. The jib boom is equipped with a rotating lifting hook and durable wear pads
installed between the inner and the outer part of the boom. With the hydraulic extension the load can be
moved accurately. The highest lifting reach is at 4,7 meters, when using with the telescopic boom of a 700
series loader.
The Telescopic 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 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 proce
dure, 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 Telescopic jib boom 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 dropping of load - Never exceed the Safe Working Load of the
attachment. The Safe Working Load of the Telescopic Jib boom itself is 800 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
extension of the telescopic jib 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 22.
Keep the loader articulation in straight position when handling heavy loads. When
turning the articulation, the loader may tilt forward.
For the best stability of the loader, keep the telescopic booms of the loader and the
jib boom fully retracted when handling loads. Ke
ep 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.

WARNING
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 loada as low and close to the loader as
poss
ible, with the telescopic boom completely retracted, to keep the centre of gravity
low.
Observe maximum load indicated in the operator’s manual of the loader. Be
especially careful when the load sensor indicator is activated, if your loader is fitted
with a load sensor system.
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 crushing hazard. The loader is not intended to
be left to keep a load elevated for longer periods. Lower the attach
ment firmly on the
ground before leaving the driver's seat and never allow anyone to be under the boom
or attachment.
Make sure that the surface can bear the total load. Also follow the correct tyre
pressure settings.
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 he
avy loads. Drive slowly and
carefully especially on inclined terrain or slippery surfaces.
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 sw
inging of
the load creates an impact or crushing hazard.
Pay attention to the surroundings and any other persons and machines moving in the
vicinity. Pay attention to the contours of the terrain and other hazards, such as
branches and trees that can rea
ch 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.
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 reg
ular 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.
