2. Designed purpose of use
The AVANT Drum type concrete mixer is an attachment suitable for use with AVANT multi purpose loaders
shown in Table 1. The concrete mixer is an essential attachment for mixing and transporting concrete, mortar,
plaster or similar material even at difficult locations. Pouring concrete to desired location is possible by simply
tilting the drum with the loader boom. The drum type concrete mixer is an ideal attachment for concrete mixing
at locations where there is no electricity available. When larger volume of concrete is needed, the Avant
concrete mixing bucket is recommended.
Operating a rotating concrete mixer includes inherent hazards that can be fully avoided only by using the
equipment carefully and in correct way. Filling the mixer and transporting or lifting a filled mixer are tasks that
require special attention. The attachment is intended for operators who have learned the safe operation of the
loader and the attachment, and are able to notice the risks arising from using the equipment and conditions of
operating area. The attachment is set to correct height and angle while sitting in the driver’s seat of the loader,
and it is also started from the driver’s seat. Driving speed must be adjusted according to operating and terrain
conditions. Unintended moving of the loader must be prevented using suitable blocks as needed in addition to
the parking brake of the loader.
The Drum type concrete mixer 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.

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 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 hydrau
lic attachment locking system, see
additional instructions about the use of the locking system from the relevant
manuals.
Ensure that the hydraulic hoses 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.

WARNING
Risk of crushing - Avoid tipping over the attachment.
Excessive tilting or lifting of an
unlocked attachment increases the risk of tipping the attachment o
ver. 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 atta
chment 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 l
oader 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 c
ompatibility 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 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.
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 is locked on or if the system is
pressurized. Connecting or disconnecting the hydr
aulic 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.

16 (28)
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 t
he
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 mu
lticonnector 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 quick attach 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.
