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 procedur
e, 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
DANGER
Risk of serious injuries - Ensure positive locking of the trailer coupling. An
unlocked trailer can move uncontrollably and cause serious injuries -
Always make
sure the trailer coupling is positively locked. Couple the trailer hitch to a correctly
sized trailer coupling only.
WARNING
Risk of tipping over - Lower the bed before leaving the driver’s seat. A trailer
may tip over, especially when its bed has been lifted. Never leave the driver’s seat
when the trailer is tipped. If the material does not slide from t
he trailer when tipping,
lower the bed before trying to assist to empty the trailer with other means. Do not
shake or twitch the trailer when it is tipped.
Risk of tipping over - Avoid overload. A load that is too heavy for the operating
conditions hind
ers the controllability of the loader. The maximum stated capacity can
not be regarded as the maximum safe load. The load must be adapted to the
operating conditions and also with the loader model in use. The warranty does not
cover for damages caused by overload.
Uneven load may cause loss of stability or hinder the controllability of the loader.
Load the trailer as evenly as possible both laterally and longitudinally. Make sure that
enough load is applied on the drawbar and the trailer hitch of the loa
der; the drawbar
load must never be negative.
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.
Make sure that the surface can bear the total load. Also follow the correct tyre
pressure settings.
Use the attachment only for its intended purpose. Other use may create unnecessary
safety risks, and the equipment may get damaged.
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 reach to the driver's area, loose rocks, and slippery
surfaces.
Shut down the loader and place the attachment to a safe position as shown in Safe
stopping procedure before any cleaning, maintenance, or adjustments.

8 (18)
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.
.
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.
Wear safety glasses e.g. when handling hydraulic components.
. ..
3.2 Safe shutdown procedure
Safe position of the attachment, before leaving the loader or the attachment unattended
WARNING
Always set the attachment to a safe position before going near the attachment.
Safe position will prevent unintentional movements of the attachment. Safe stopping
procedure:

Lower the boom completely down (and lower any attachment possibly fitted on the
loader boom on the ground).
Shut down the loader engine and lock the parking brake.
Prevent moving of an uncoupled attachment. Use blocks if necessary.


5. Assembling the attachment
Attaching the attachment on the rear of the loader is quick and easy, but it must be done carefully. The
attachment is mounted to the rear of the loader by using M12 bolts (4 pcs) and thread locking compound.
If the attachment is not mounted properly, it may detach from the loader and cause a hazardous situation. The
loader must not be driven if the attachment has not been fixed properly.
5.1 Connecting and disconnecting hydraulic hoses
WARNING
Risk of movement of the attachment and ejection of hydraulic oil -
Never connect
or disconnect quick couplings or other hydraulic components while the control
lever of the auxiliary hydraulics con
trol lever is locked on or if the system is
pressurized.
Connecting or disconnecting the hydraulic couplings while the system is
pressurized may lead to unintended movements of the attachment, or ejection of high-
pressure fluid, which can cause serious inj
uries or burns. Follow safe stopping procedure
before disconnecting hydraulics.
Keep all fittings as clean as possible; use the protective caps on both the attachment and
the loader. Dirt, ice, etc. may make using the fittings significantly more dif
ficult. Never
leave the hoses hanging on the ground; place the couplings onto the holder on the
attachment.
When uncoupling the attachment, always disconnect the hydraulic couplings before
removing the trailer hitch, to prevent hose damage and any oi
l spills. Reinstall the
protective caps on the fittings to prevent water, dirt, and other impurities from entering the
hydraulic system.

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
Make sure the loader is compatible with the attachment.
Stability of the loader,
possible overload of the attachment, and compatibility of loader control 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 , ask your Avant dealer before using this attachment.
WARNING
Avoid running over persons - Check surroundings before driving.
Always look in the
direction the loader is moving. Before reversing, always ensure that bystanders,
especially children, are at a safe distance to avoid back-over accidents.
6.1 Checks before use
Make sure that other persons are at a safe distance from the loader and the attachment. Never
operate the loader if another person is close to the loader. Always make sure that it is safe to reverse
with the loader.
Ensure that the ground surface is level and solid enough for safe operation.
Check the general condition of the attachment and the loader. The attachment must not be used, if it
and the loader are not in good working condition.
Operate the attachment only while 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.
Remove all obstacles from the operating area beforehand. Remember correct and healthy working
methods and avoid leaving the driver’s seat unnecessarily.

6.3 Use
Before starting to work:
Read all safety instructions.
Using the Hydraulic trailer hitch:
When transporting load with the trailer hitch, make sure that the load is well balanced and stays firmly. The
load must be transported calmly, and the swinging of the load must be avoided. Always drive slowly while
operating the Hydraulic trailer hitch. Adjust the drive speed according to the operating conditions and the
ground.
Avoid sharp turns while towing trailers.
6.4 Storage
Uncouple and store the attachment on level ground. The best way to store the attachment is a place where it
is protected from direct sunlight, rain, and extreme temperatures.
Avoid leaving the attachment
laying di
rectly on the ground.
Place it on blocks of wood or
on a pallet, for example.

Never leave the hydraulic
connectors on the ground.


7. Maintenance and Service
The attachment has been designed to be as maintenance free as possible. Continuous maintenance includes
regular cleaning and lubrication, and monitoring the condition of the attachment. Because of the crushing
hazard caused by lowering machine parts, all maintenance work must be done when moving parts have been
lowered down completely and the attachment is lowered flat against the ground.
DANGER
Risk of crushing - Never go under lifted attachment.
Make sure the attachment is
properly supported during all maintenance work. Never go under a lifted attachment. The
loader boom may lower unexpectedly duri
ng maintenance causing serious injuries from
crushing or impact even when the loader engine is not running. All maintenance and
service must be performed when the attachment has been lowered down to a safe
position.
7.1 Inspection of hydraulic components
Check the condition of the hydraulic hoses and components when the engine has been turned off, system has
cooled down, and the pressure has been relieved. Do not use the equipment, if you have discovered a leak in
the hydraulic system of the attachment or the loader. Leaking hydraulic fluid may penetrate skin and cause
serious injuries. Seek medical attention immediately in case hydraulic fluid penetrates the skin. Wash any part
of body that has been in contact with hydraulic oil carefully with water and soap. Hydraulic fluid is also harmful
to the environment and any leak to the environment must be prevented. Repair all leaks immediately after
detecting them; a small leak can quickly grow into a big one. Operate the attachment only with type of
hydraulic oil that is accepted for use in Avant loaders.
DANGER
Risk of high pressure fluid injection
through skin -
Release residual pressure
before maintenance.
Never handle hydraulic
components when the hydraulic system is
pressurised, since a fitting may break o
r
become loose and the released oil may cause
serious injuries. Do not use the equipment, if
you have discovered a fault in the hydraulic
system.
Check hoses visually for cracks or abrasions. If there are signs of leaks, to check a component, hold up a
piece of cardboard in the area where a leak is suspected. Do not use hands to search for leaks. Monitor the
wearing of the hoses and stop the use, if the surface layer of any hose has worn off. Check the routing of the
hoses; adjust the hose clamps to avoid abrasion to the hoses. The hoses have limited service life. Depending
on operating conditions all hoses must be inspected thoroughly no later than after 3 to 5 years of use, and if
required, they must be replaced with new ones.
Finding any fault means that the hydraulic hose or component must be replaced and the equipment must not
be used until it is repaired. Spare parts are available from your nearest AVANT retailer or authorised service
point. Leave the repair work to professional service technicians, if you don’t have adequate knowledge and
experience about hydraulic assemblies and how to perform the repairing safely.

15 (18)
7.2 Cleaning the attachment
Clean the attachment regularly to prevent accumulation of dirt which is more difficult to remove. A pressure
washer and mild detergent can be used for cleaning. Do not use strong solvents, and do not spray directly at
the hydraulic components, or at the labels on the attachment.
7.3 Lubrication
There is one lubricating point at the end of the
hydraulic cylinder.
Ap
propriate lubrication interval depends heavily
on operating conditions, but lubricant must be
added at least after every 10 hours of use.
Adequate lubrication must be ensured, and if the
bearings are dirty, lubricant must be added; added
lubricant will push out dirt.
Clean the end of the nipple before greasing and
add only a small amount of grease at a time. All
lubrication nipples are standard R1/8" nipples.
Replace any damaged nipples.
7.4 Inspection of metal structures
Also the metal structures of the attachment must be inspected regularly. Check visually for damages and
inspect the quick attach brackets and their surrounding area carefully. The attachment must not be used if it is
deformed, cracked, or torn.
Welding repairs are only allowed to be carried out by professional welders. When welding, only methods and
additives suited for steel used in attachment must be used. For more information about repairs contact your
nearest service point.
7.5 End of life disposal
When the attachment is at the end of its useful life recycle and dispose of the attachment properly. Dismantle
the attachment and separate the different materials, such as plastic, steel, rubber, and oils, for example. Drain
and collect all oils and handle them by following the current local regulations. Never leave any oil or other
material in the environment.
Recycle each material by delivering them to a proper collecting place. Let a waste management company do
the recycling, if possible.

16 (18)
