2. Designed purpose of use
The AVANT Mini digger 180 is an attachment that is suitable for use with AVANT compact loaders that are
shown in Table 1. The digger is designed for occasional use as a quick and simple to use digging attachment,
that is also easy to transport. It mounts directly on the quick coupling plate of the loader. The digger is
controlled with the articulated boom, and the bucket of the digger is operated with the auxiliary hydraulics of
the loader.
The robust digger can be used with several available bucket options in general excavation, and moving and
loading of soil. Changing of bucket on the Mini digger 180 is fast and easy with the standard S30-150 type
bucket quick coupling system. The bucket can also be mounted pointing forward if necessary. The mini digger
can be equipped with either the bucket tilt adapter, or the hydraulic thumb, which are available as optional
equipment. In this manual instructions to install these options are shown for experienced users.
To operate the bucket tilt adapter or the excavator thumb, the loader must be equipped with Opticontrol®
attachment control system, or the wire harness A437338* must be retrofitted to the loader.
The digger is controlled from the operator’s seat of the loader by using the controls of the boom and auxiliary
hydraulics of the loader. Excavated soil is dumped to sides by taking use of the articulation of the digger and
driving of the loader. Soil can be easily loaded high using the reach of the loader boom. The control patterns
of a mini digger differ from conventional excavators and backhoes. However, also inexperienced operators
and operators who are used with other types of excavators can easily assimilate with safe and efficient use of
the controls. All operators of this attachment must get familiarised with typical hazards related to any
excavation work. Before starting any digging operation the operator of the equipment must find out if there are
objects in the ground that may cause hazards.
Recommended options for the most efficient use are telescopic boom on the loader and the optional
Opticontrol®system.
Use the digger only for occasional excavations with original buckets, tools, and options. The digger must not
be used for lifting of objects. Never use the attachment to lift objects or loads other than materials that are
normally handled with a bucket. Never suspend any loads or attach other tools than a bucket. The Mini digger
180 is not designed for any other use than what is specified in this manual and it must not be used for any
other purposes than what it 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 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.
This attachment is designed to b
e 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 electric shock - Plan all excavation tasks ahead before you dig! Find out
about the possibility of having any electric cable, gas pipe, water pipe,
communications cable or similar buried in the ground. Consult local authorities,
electric, water, tele
communications, and gas companies, and other relevant sources
before starting to use the equipment. Your area may also have a specific hotline or
helpdesk available, or a special permit may be required. If uncertain in any way, seek
for more information before starting to dig.
Tipping over hazard - Note that the excavation or trench may suddenly cave in.
Exercise extreme caution when driving near ditches or embankments, and avoid
driving along a ditch or trench, as the machine could suddenly tip over if
an edge
caves in. Avoid driving along trenches and keep at least a distance equal to width of
a trench. Consider the risk and possibility of caving in. Do not dig excavation with
vertical side walls, slope the excavation according to the type of soil, amo
ng other
considerations.
Crushing hazard - Make sure that the bucket is securely fitted. Loose or falling
bucket can cause serious injuries.
Risk of crushing and falling objects - The attachment must not be used for any
other purposes than intended.
Never use the attachment to lift objects or loads
other than materials that are normally handled with a bucket. Never suspend any
loads or attach any other tools than a bucket to the backhoe. Make sure that the
loader is parked when operating the backhoe.
Risk of crushing - Keep in mind that the loader boom and the attachment can
be lowered or tilted even if the engine has been shut down.
Never leave the
driver’s seat when the bucket is lifted off from the ground. Keep hands and feet away
from moving parts.

WARNING
Operate only on well lit areas. If extra caution is required to avoid hitting dangerous
or fragile materials in the ground, have another person nearby to spot possible buried
items.
Do not use the digger on horizontally tilted terrain. Ensure the stability of the loader
and firmness of the ground also on even terrain.
Pay attention to the surroundings and any other persons and machines moving in the
vicinity. Other persons must keep safety distance of 2 meters. Pay attention to the
contour
s 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 not to tilt the digger too far up causing material to fall from the bucket on
the loader or operator’s area.
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.
Ensure that ventilation is sufficient when operating indoors. Do not operate the loader
in closed spaces regardless of the engine or fuel type. Exhaust gases may
concentrate to hazardous levels.
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.
Carrying heavy loads can shift the centre of gravity of the loader and lead to tipping
over of the loader. Always transport the load as low and close to the machine as
possible with the telescopic boom completely retracted to keep the centre of gravity
low and for the best stability.
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 attachment or the loader
are not intended to be left to keep a load elevated for longer periods. Lower the
attachment before leaving the driver's seat.
Never use the attachment to lift or to transport persons or as any kind of work
platform even temporarily.
Keep the loader articulation in straight position when handling heavy loads. When
turning the articulation, the loader may tilt forward.
Shut down the loader and place the attachment to a safe position as shown in Safe
stopping procedure before any cleaning, maintenance, or adjustments.
Observe maximum load indicated in the operator’s manual of the loader. Be
especially careful when the load sensor indicator is activated.
Make sure that the surface can bear the total load. Also follow the correct tyre
pressure settings.
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.
Use the attachment only for its intended purpose. Other use may create unnecessary
safety risks, and the equipment may get damaged.

5. Assembling 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
plate 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 o
perator's
manual of the loader.

Make sure that the hydraulic hoses and the electric cables 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 coupling plate hydraulically to an obliquely forward position.

Drive the loader onto the attachment. If your loader is equipped with a
telescopic boom, you can use it to reach to the coupling brackets of the
attachment.

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 lift the
attachment just off the ground.
Turn the
boom control lever left to turn the bottom section of the quick coupling
plate of the loader onto the attachment.
Lock the locking pins manually or lock the hydraulic locking.
Always check the locking of both locking pins.

17 (44)
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 gr
ound. 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 , ask your Avant dealer before using this attachment.
5.1 Connecting and disconnecting hydraulic hoses
On Avant loaders the hydraulic hoses are connected using the multi connector system. If you have an older
model Avant 300-700 series loader with the conventional quick couplers, and you want to change to the multi
connector system, contact your Avant dealer or service point for instructions or installation services.
WARNING
Risk of movement of the attachment and ejection of hydraulic oil -
Never connect
or disconnect quick couplings or other hydraulic component
s while the control
lever of the auxiliary hydraulics control 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 injuries or burns. Follow safe stopping procedure
before disconnecting hydraulics.

18 (44)
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 difficult. Never
leave the hoses hanging on the ground; place the couplings onto the holder on the
attachment.
Connecting the multiconnector system:
1.
Align the pins of the attachment connector with corresponding
holes of the loader connector. The multiconnector will not connect
if the attachment connector is upside down.
2.
Connect and lock the multiconnector by turning the lever towards
the loader.
The lever should move easily all the way to its locking position. If the lever does not slide smoothly, check the
alignment and position of the connector and clean the connectors. Also shut down the loader and release the
residual hydraulic pressure, see page .
To disconnect the multiconnector system:
Before disconnecting put the attachment down on a solid and even
surface.
1. Switch off the auxiliary hydraulics of the loader.
2.
While pushing unlock button, turn the lever to disconnect the
connector.
3. After ending operation put the multiconnector on its hol
der on the
attachment.
Disconnecting hydraulic hoses:
Before disconnecting the fittings, lower the attachment to safe position on solid and level surface. Turn the
control lever of the auxiliary hydraulics to its neutral position.
When uncoupling t
he attachment, always disconnect the hydraulic couplings before
unlocking the quick coupling plate, to prevent hose damage and any oil spills. Reinstall
the protective caps on the fittings to prevent impurities from entering the hydraulic
system.
Releasing residual hydraulic pressure:
In case residual pressure is left in the hydraulic system of the attachment, it is often possible to disconnect the
hydraulic couplings, but it may be difficult to connect them the next time. If the fittings will not connect, the
residual pressure must be released by turning the auxiliary hydraulics control lever of the loader, when the
engine is turned off. To make sure that there will not be residual pressure in the hydraulic system of the
attachment, shut down the loader engine and move the auxiliary hydraulics control lever of the loader back
and forth before disconnecting the couplings.

5.2 Electric connection
Electric functions of the attachment:
To control the hydraulic functions of a Mini digger 180, the loader must be equipped with the Opticontrol®
system (optional equipment for loaders). With the Opticontrol®system all functions of the attachments can be
controlled with the buttons on the joystick of the loader. When you push the switches on the joystick,
Opticontrol activates the auxiliary hydraulics of the loader simultaneously and makes direct control of all
functions possible.
The functionality of the Opticontrol system is available as a retrofit kit A437338. See separate instructions
about retrofitting of the wire harness from the instructions of the retrofit kit.
5.2.1 To connect the electric harness of the attachment to the loader
Opticontrol (R) is required to operate all functions of this attachment.
If your loader is equipped with the Opticontrol (R)
system, the electric socket for attachments is integrated
into the multiconnector. The electric harness of the
attachment is connected when the multiconnector is
coupled.
Clean both multiconnectors before connecting them.
Opticontrol®, Opticontrol (R) socket in
multiconnector
If your loader is not equipped with the Opticontrol®:
All functions of the Mini digger 180 can't be used without the Opticontrol®system on the loader.
Make sure that electric cables will not get stuck, squeezed, or stretched when the
equipment moves.
With the help of the opticontrol available for the loader, the attachment control switches
are easily accessible at the end of the boom control lever.
More information about the power outlet of the loader can be f
ound in the operator’s
manual of the loader.

20 (44)
5.3 Uncoupling the digger and correct storage position
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 as indicated with an arrow in the figure below. 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.
Correct storage position:
Before uncoupling the digger, turn the
bucket so that it will be in level with the
digger frame, or t
ilted slightly up, as
shown in adjacent figure. In this way it will
be easy to connect the digger to the
loader.
Store the digger on level ground on a
pallet, for example, so that it is easier to
couple to the loader, and will not be in
contact with ground.
WARNING
Risk of tipping over -
Store the
digger properly according to
instructions.
If the digger is left in a
position shown in the adjacent figure,
it’s centre of gravity will be high from
ground and the digger may tip over
easily, causing ha
zards of crushing
and impact to anyone near the
attachment.
Storage in any other position than
shown above will result in hazard of
tipping over and is prohibited.
