2. Designed purpose of use
The AVANT Hydraulic boom is an attachment suitable for use with AVANT multi purpose loaders shown in
Table 1. The hydraulic boom is intended to be used with a suitable attachment, when bigger outreach than
usually is necessary.
The hydraulic boom is equipped with S30 quick coupling, which allows the boom to be used with an
attachment equipped with similar counterpart. The attachment with hydraulic boom can reach to places where
it is not possible to drive with the machine. This makes working on hard-to-reach areas safe and easy.
Depending on the attachment, the visibility is usually excellent to the whole working area. The operator can
look into the driving direction when processing the terrain.
It is recommended that the Avant is equipped with a cab (L, LX or DLX) in order to protect the driver against
flying debris. When mounted on Avant 600 series, the extra side weights (A49063) are also recommended for
better stability.
The hydraulic 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 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.

Make sure Flail mower or other attachment is securely connected to the hydraulic
boom. Always refer also to the operator's manual of the separate attachment.
The hydraulic boom and any attachment coupled to it are 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 both the side extensi
on telescopic boom and the telescopic boom of the
loader completely 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 spe
ed or
direction to maintain balance of the loader especially when handling heavy loads.
Drive slowly and carefully especially on inclined terrain or slippery surfaces.
Keep the loader articulation in straight position when handling heavy loads. When
turning the articulation, the loader may tilt forward
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 leave the driver’s seat when the attachment is running or if the auxiliary
hydraulics control lever is locked on. The rotating parts of the attachment keep
rotating for a short period after the hydraulic supply has
been shut off. Wait until all
parts have stopped completely before leaving the driver's seat.
Do not leave the driver’s seat when the loader boom is lifted. Going under a raised
attachment or loader boom is dangerous. Always remember that the boom may lower
due to loss of stability, mechanical fault, or if another person operates the controls of
the loader.
Hazard of entanglement - Never wear loose clothes, such as loose shoelaces, or
long scarves when working with the attachment. Keep hands and fe
et away from
moving components.

8 (30)
Use the attachment only for its intended use and only with original tools and spare
parts.
When unlocking and dismounting the attachment off from the loader, ensure that it is
secured against accidental movement. To s
ecure the attachment from tipping over
lower it firmly on the ground and disconnect only on level surface. Ensure the
attachment is properly supported during storage. Never climb on the attachment.
Make sure that the attachment is properly supported before performing any
inspections, maintenance, or adjustments. If necessary, secure the attachment with
suitable lifting equipment, or lower it on firm blocks of wood, for example.
Always transport the hydraulic boom as low and as close to the machine as possible
to keep the centre of gravity low. Keep the hydraulic boom completely retracted
during transport. On slippery surfaces drive slowly and deliberately. Operate the
controls of the loader slowly and calmly especially on inclined terrain.
Shut down the loader and place the attachment to a safe position as shown in Safe
stopping procedure before any cleaning, maintenance, or adjustments.
Pay attention to the surroundings and any other persons and machines moving in the
vicinity. Pay attention to t
he 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 to use only an attachment that is in good condition. Do not modify the
attachment in any way that could affect its safety.
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
Wrong, improper, or careless use of the attachment causes serious risk of severe
injuries or death.
Familiarise yourself with the controls of the loader in a safe area. Pay
particular attention to the safe stopping of the attachment and the loader; fo
llow the safe
stopping procedure shown in this manual before leaving the driver's seat.
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

9 (30)
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.
Wear safety glasses when handling hydraulic components.
. ..
Safe stopping of the attachment, before going near the attachment:
WARNING
Always stop the attachment 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.
