2. Designed purpose of use
The AVANT Leaf blower is an attachment that is suitable for use with AVANT multi purpose loaders that are
shown in Table 1. The Leaf blower propels air through a controllable blower chute to move leaves and grass
cuttings from pathways, yard areas, and other paved surfaces. The Leaf blower is suitable also for
professional use.
The Leaf blower is equipped with a powerful hydraulic motor for efficient operation even when handling damp
leaves. As standard, the leaf blower chute can be turned electrically by 235 degrees directly from the driver’s
seat, 90 degrees to the left and 145 degrees to the right from the straight forward pointing direction. The
electrical turning can be controlled with a switch delivered with the attachment, or with the Opticontrol®
attachment control system, which is optional equipment for loaders. In frequent use the Opticontrol®system is
recommended.
As standard, the Leaf blower is equipped with manual throwing height adjustment. The optional electric
throwing height adjustment can be operated only with the optional Opticontrol®system, or with the attachment
control switch pack. The Leaf blower is not designed for any other use than what is specified in this manual
and must not be used for any other purposes than what is intended for. The leaf blower is intended for blowing
of air only. It must not be used as any kind of vacuum unit, or as a spreader.
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.

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 load
er 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 operator'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 pi
ns 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.

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 locki
ng 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 o
verload 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 i
nclude 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.
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 c
omponents 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.

14 (28)
Keep all fittings as clean as possible; use the protective caps on both the attachment and
the loader. D
irt, 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.
To disconnect the multiconnector system:
B
efore 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 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.
