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 attach plate on the loader boom and the counterpart on the
attachment.
If the attachment is not locked to the loader, it may detach from the loader and cause a hazardous situation.
The loader must not be driven and the boom must never be lifted when the attachment has not been locked.
To prevent hazardous situations, always follow the coupling procedure shown below. Also remember the
safety instructions shown in this manual. The attachment is mounted to the loader as follows:
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 quick attach plate locking pins 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 relevant
manuals.
 Ensure that the hydraulic hoses and the electric harness are not in the way
during installation.
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:
 Lift the boom slightly – pull the boom control lever backward to raise the
attachment off the ground.
 Turn the boom control lever left to turn the bottom section of the quick attach
plate onto the attachment.
 Lock the locking pins manually or lock the hydraulic locking.
 Always check the locking of both locking pins.

WARNING
Risk of crushing - Avoid tipping over the attachment.
Excessive tilting or lifting of an unlocked 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 are 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 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 6, ask your Avant dealer before using this attachment.

6. Instructions for use
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 practice its use without any attachments.
6.1 Checks before use
 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.
 Check the general condition of the attachment and the loader, and check for possible hydraulic oil
leaks. The attachment must not be used, if there is a fault in the hydraulic system of the loader or the
attachment. Refer to Chapter 7 for maintenance instructions.
 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.
 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.
 Remember correct working methods and avoid leaving the driver’s seat unnecessarily.
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.

6.3 Operating the ripper
Use the ripper for removing e.g roots and rocks from hard packed ground. The ripper is operated by pressing
the three blades into the ground next to the object you wish to remove. When the teeth have sunk into the
ground, tilt the ripper inwards and then lift the boom upwards, which will bring the object on top of the ground.
6.4 Working on uneven ground
Extra caution is needed when using the equipment on inclined terrains and slopes. Drive slowly especially on
inclined, uneven, or slippery surfaces, and avoid sudden changes in speed or direction. Operate the controls
of the loader with careful and smooth movements. Watch out for ditches, holes on the ground, and other
obstacles, as hitting an obstacle may cause the loader to tip over.
Maximum lifting capacity can not be achieved on inclined terrain. On horizontally tilted terrain the load must
not be lifted high. The loader frame articulation should be kept straight when lifting heavy loads; turning the
load during lifting operation will affect the stability of the loader and may lead to overturning of the machine.

.
6.5 Transport position
CAUTION
Keep the loader stable. Always
transport the ripper as low and
close to the ground as possible.
Keep the telescopic boom retracted
during drive.
6.6 Storing the attachment
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 directly on the ground. Place it on blocks of wood or on a pallet, for
example.
 Place the multiconnector on to its holder. Never leave the hydraulic connector on the ground.
 Make sure that the attachment is secured against all movements during storage.
Never climb on the attachment.
For longer storage periods touch up the paint where needed in order to prevent rust damage.

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 during 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 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 bucket must be used. For more information about repairs contact your
nearest service point.
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 Ripper teeth maintenance
The condition of the teeth and mounting pins should be checked at least every few uses. Replace any broken
items.
