2. Designed purpose of use
The AVANT Mounting kit for stone installation clamp is an attachment that is intended to be used with AVANT
multi purpose loaders that are listed in Table 1 below. It is intended to be used together with a hydraulic stone
installation clamp. The Mounting kit is equipped with hydraulically driven rotator and electric selector valve for
switching between the rotation and two functions of a stone installation clamp. The strong and robust rotator is
equipped with round shaft and pin locking system.
The selector valve of the Mounting kit for hydraulic stone installation clamp makes it possible to use all three
hydraulic functions with only one auxiliary hydraulics outlet of the loader. To operate all of these functions, the
loader must be equipped with Opticontrol®attachment control system, or the wire harness A437338* must be
retrofitted to the loader. Also, the loader must be equipped with the 6/8-function joystick for auxiliary hydraulics
control.
When working with a stone installation clamp, one or two assisting persons may be needed to lay and align
the stones correctly. The operator of the stone installation clamp and other controls of the loader must be
seated on the driver's seat. The operator of the loader must move the loader, its boom, and the attachment in
a way that does not cause any hazard for the assisting persons. Loads must never be lifted above people.
The Mounting kit for stone installation clamp 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 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.

correct coupling procedure, and the correct wa
y 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.
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 crushing under the attachment or the loader boom - Lower the
attachment firmly on the ground before leaving the driver’s seat.
Make sure that
the attachmen
t is properly supported during any maintenance or inspections. Do not
leave the driver’s seat when the loader boom is lifted. Going under a raised
attachment or loader boom is dangerous, as the boom may lower due to loss of
stability, mechanical fault, or if another person operates the controls of the loader.
Risk of dropping of load and misuse - Make sure you have the operator's
manual of the hydraulic stone installation clamp in your language.
Use the
stone installation clamp only for lifting of stones
that can be lifted evenly with the
hydraulic clamp, some types of stones will drop. Do not use the Hydraulic stone
installation clamp if you don't have the operator's manual available. Contact your
Avant dealer.
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 heavy load
s. Drive slowly and
carefully especially on inclined terrain or slippery surfaces.
When unlocking and dismounting the attachment off from the loader, ensure that it is
secured against accidental movement. To secure 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.
Keep the loader articulation in straight position when handling heavy loads. When
turning the articulation, the loader may tilt forward.
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.
Never use the attachment to lift or to transport persons or as any kind of work
platform even temporarily.

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. 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.
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.
WARNING
Risk of tipping over - Avoid overload.
Loader can tip over
when handling too heavy loads, or because of dynamic
movements caused by driving with and handling of a heavy
load. Do not extend the telescop
ic boom when the load
approaches the lifting capacity of the loader, or when the
loader boom is in horizontal position. When you notice that
the rear wheels of the loader are about to lift from the ground,
or if the load indicator of the loader (if fitted) signals:
Lower the load calmly and retract the telescopic boom
Avoid sudden changes in speed or direction whenever load is lifted
Use additional counterweights as needed
WARNING
Risk of crushing -
Never allow anyone to get under a
lifted attachment or loader boom.

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 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 loc
king 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.

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 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 u
nder
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 incre
ases 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 rais
e 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 posit
ion 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
WARNING
Prevent oil spill - Check that the hydraulic hoses of the stone installation clamp are
connected to the rotator, or that the hydraulic fittings of the rotator are plugged, if
hoses are not fitted.
Never connect the multiconnector unless the hydraulic ports of the
rotator are not plugged and hydraul
ic hoses are not connected. If the Stone installation
clamp has been assembled and used with the Mounting kit before, you can continue to
connect the multiconnector to the loader. See instructions to connect hydraulic fittings in
this manual.
On Avant loaders the hydraulic hoses are connected using the multi connector system. If you have an Avant
300-700 series loader with the conventional quick couplers and wish to change to the multi connector system,
contact your Avant dealer or service point for instructions or installation services.

14 (32)
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 control lever i
s 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 bur
ns. 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 difficult. Neve
r
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 wil
l 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.
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 holder 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 the attachment, always disconnect the hydraulic couplings before
unlocking the qu
ick 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.

locking pin (3).
Do not lift or move the stone
installation clamp until the
rotator is fully connected to it.
It is also possible to rotate the Stone clamp manually by opening check valve completely.
The check valve is located under the control valve of the rotator, see page 24.
5.3 Connecting Mounting kit hydraulics
WARNING
Prevent spilling of hydraulic oil -
Make sure the multiconnector is not connected to
the loader. If the multiconnector has been coupled before, release an
y residual pressure
from the hydraulic hoses by following the safe stopping procedure. Disconnect the
multiconnector before starting to install the hydraulic hoses.
Connect the hydraulic fittings from the rotator to the stone installation clamp as follows:
1.
Grapple, open
2. Grapple, close
3. Side grippers, open
4. Side grippers, close
The rotator is equipped with G 1/4" internal threads. The
hydraulic hoses are possible to install both BSSP and
DIN type connectors (delivered with the rotator).
Remove the protective
caps from the fittings before
installation.
Also make sure that there is no residual pressure in the
hydraulic system before installation. Always uncouple

5.3.1 Safety instructions for hydraulic assemblies
High-pressure ejection of fluid may penetrate skin and cause serious injuries:
DANGER
Risk of high pressure fluid injection
through skin - High-
pressure ejection of
fluid may penetrate skin and cause serious
injuries.
Before handling hydraulic components, make
sure that the hydraulic system of the
attachment and the loader are completely
depressurized. Never handle pressurized
fittings.
Never hold your hand tightly around or near a
fitting when tightening or opening it, or when
searching for leaks. Use a piece of cardboard
to find leaks.
Seek medical attention immediately in case
hydraulic fluid is injected through the s
kin. Also
general skin contact with the oil can be
harmful. Always wear protective gloves, safety
goggles and protective clothing.

hydraulic cylinders.
Use additional supports or lifting equipment as needed.
3. Shut down the loader engine.
4. Mov
e the auxiliary hydraulics control lever to its extreme positions several times to
release residual pressure.
5.
Uncouple the multiconnector or quick couplings from the auxiliary hydraulics of the
loader to prevent draining of hydraulic oil.

18 (32)
5.3.2 Tightening hydraulic fittings
Tighten the fittings carefully according to given instructions and safety procedures. Keep in mind that over
tightening will break a fitting. Tighten basic fittings carefully with hand tools using moderate torque. The elbow
fittings should be tightened at last, after hoses have been fitted to their clamps.
1. Allow the hydraulic systems of the loader and of the attachment to cool down completely before any
work on hydraulic systems.
2. Make sure that the loader boom or any other part of the attachment can’t move causing crushing or
pinching hazards:

es, or going near any hydraulic fitting,
to avoid possible ejection of pressurized hydraulic oil:
Shut down the loader engine
Depressurize the hydraulic system completely

Wipe the hydraulic components clean to find leaks more
easily.
Place pieces of cardboard around the fittings to detect leaks.

Start the engine. While running on idle, operate the auxiliary
hydraulics control lever briefly a couple of times. Shut down
the engine, depressurize the hydraulics, and check for any
sign of leak. Tighten if necessary.

Repeat the test by gradually increasing engine rpm and
operating time. Use both directions of the auxiliary hydraulics
control lever.
DANGER
Risk of high pressure fluid injection through skin -
Test the tightness of the
hydraulic fittings carefully.
Use idle rpm when starting the first time and keep a safe
distance due to the risk of hydraulic fluid ejection. Shut down the loader and release the
residual pressure before checking for leaks. Remember to use and wear protective
equipment.
DANGER
Risk of high pressure fluid injection through skin -
Never test the tightness of the
hydraulic components by placing hands near the fittings.
Never tighten a
pressurized hydraulic fitting, since the fitting may break and the released oil may cause
serious injuries.
Check the routing of hoses and movements of the attachment
After tightening the hydraulic components, test the movements of the attachment thoroughly. Check that the
hydraulic hoses cannot get stretched or pinched in any position of the loader boom or the attachment, and
check that the hoses are not in contact with sharp edges.

5.4 Electric connection
Electric functions of the attachment:
To control the hydraulic functions of a Stone installation attachment that is connected to the Mounting kit, the
loader must be equipped with the Opticontrol®system (optional equipment for loaders). When you push the
switches of the attachment control switch pack, Opticontrol activates the auxiliary hydraulics of the loader
simultaneously and makes direct control of all functions possible.
If the loader is not equipped with the Opticontrol®system, it would be necessary to push a switch of the
attachment control switch pack at the same time when operating the auxiliary hydraulics control lever of the
loader. Using the attachment this way is not recommended. It is suitable only for testing purposes. 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.
The loader must be equipped with the Opticontrol system in order to make all functions of
