2. Designed purpose of use
The AVANT Vacuum brush is an attachment that is suitable for use with AVANT multi purpose loaders that
are shown in Table 1. The vacuum brush is intended for collecting of tree leaves or other light materials in
parks, lawns, yards and similar areas. The vacuum brush is not suitable for collecting sanding gravel, litter, or
other heavier or abrasive materials. The vacuum brush is not intended to collect soaked, wet tree leaves or to
be operated in rain. The collecting performance decreases when the collected material is wet. Operating in
wet conditions can cause more frequent blockages, depending on the material and operating conditions. The
Vacuum brush is suitable for residential and professional use as well.
The powerful vacuum unit sucks the waste through a wide nozzle below the unit, with a wide coverage at a
single drive. The nozzle is also fitted with a rotating broom that loosens more compacted leaves and waste.
The vacuum unit, which is operated by its separate hydraulic motor, compacts loose materials into a tight
package into the collector box. The collector box level can be monitored and the collector box can be emptied
from the driver's seat by using the loader boom to lift and tilt the attachment. As an option, a handheld
vacuuming kit is available. With the flexible tube of the kit, it is easy to clean areas that are otherwise hard to
reach. When operating the handheld kit, the parking brake of the loader must be engaged.
The blower unit is equipped with blades to shred the collected material and to help to avoid blockages. The
vacuum brush is equipped with the OptiFloat® floating system, which allows the attachment to follow the
ground contours eliminating the need for the loader boom floating. In addition, the float system enables
efficient side tilting of the equipment.
The Vacuum brush 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 l
ocking 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 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.

14 (40)
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 lock
ed. 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 attachme
nt 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.
The Vacuum brush is equipped with mechanical floating system OptiFloat®, which allows
the attachment to move and tilt while it is placed on the ground. The floating movement is
restricted by means of chain type limiters to prevent the attachment to
tip onto the loader
boom. However, in some positions of the loader boom and the attachment it may possible
to turn the attachment to a position where it tips over onto the loader boom. Avoid tilting
the attachment too much towards the loader boom. Always
keep the attachment close to
the ground and stable to avoid damage from contact with the loader boom.

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 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.
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.
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 dis
connect the
connector.
3.
After ending operation put the multiconnector on its holder on the
attachment.

16 (40)
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 t
he 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.

6. Instructions for use
Check the attachment and the operating environment once more before starting to work, and that all obstacles
have been removed from the operating area. Quick inspection of the equipment and the operating area before
use are parts of ensuring safety and the best performance of the equipment.
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 telescopic boom when the load
approaches the lifti
ng 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
6.1 Checks before use
Remove or mark visibly all obstacles, such as trash, large tree branches or stones, from the working
area before operation. Check the area for possible hidden ditches, manholes, or other dangerous
areas. Remember that tall grass can hide obstacles.
Set and lock all four wheels of the attachment to same height.
Before each use, check the operation of the attachment and ensure that the brushes can rotate freely.
Check that there is no string or other foreign material coiled around the brushes or the blower unit.
Check that the brushes are intact and in good condition. Check the blower unit and the connections of
the collecting hose.
Check that the collector box is empty, the collector box door firmly shut, and that the collector tubes
and fan are not blocked or damaged.
Keep the collector fan clean and remove debris that has become stuck to prevent blockages.
Check the operation of the safety valve; see page 24 for instructions about floating and the operation
of the safety valve.
Check that all obstacles, including any hidden ones, have been removed from the working area before
operation.

18 (40)
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.
WARNING
Avoid running over persons - Check surroundings before driving.
Always look in the
direction the loader is moving. Before r
eversing, always ensure that bystanders,
especially children, are at a safe distance to avoid back-over accidents.
WARNING
Risk of tipping over -
Avoid overload and keep heavy load close to the loader. Keep
loads close to the ground whenever driving
, especially during turns and uneven
terrain.
Pay attention that a heavy load or long distance between the loader and the
centre of gravity of the load will affect the balance and handling of the loader. The use of
additional counterweights is recommended
especially when operating smaller loader
models. With heavy loads, the telescopic boom must be kept retracted while moving with
the loader. Always wear seat belt.
DANGER
Risk of serious personal injuries - Never leave the equipment running unattended.
Start the attachment only when it is ready to be used. Do not go near the equipment
when another person operates the controls of the loader.
WARNING
Risk of serious personal injuries -
Never use damaged attachments or if parts are
missing. Before
using the vacuum brush, check that it is intact and that all protective
covers and the suction hoses are in place. Close the collector box door. Do not use the
vacuum brush with the box open, as the door may get damaged or the brush may throw
items at a high velocity.

19 (40)
.
6.2 Using the Vacuum brush
19Set and adjust the Vacuum brush to correct operating position before starting the attachment. See the
following chapters about floating system and adjustments.
Starting the Vacuum brush:
When the Vacuum brush is on the ground
Move the auxiliary hydraulics control lever of the loader towards its locking
position to start the Vacuum brush. The vacuum unit and brush start at the
same time.
Stop by releasing the lever to neutral position.
Release the lever to its neutral position whenever not operating.
When the Vacuum brush is off the ground
Move the auxiliary hydraulics control lever of the loader towards its locking
position to close the collector door.
When the Vacuum brush is off the ground
Move the auxiliary hydraulics control lever of the loader away from its
locking position (Reverse direction) to open the collector door.
When the Vacuum brush is on the ground
The brush will only rotate to intended running direction. Reverse
direction of
the auxiliary hydraulics control has no effect, when the attachment is
lowered on the ground.
.
Operate the controls of the loader and its
attachment in a careful and smooth
manner. Avoid sharp turns and sudden
changes in speed or directio
n whenever
using the Vacuum brush.
For the best performance, set the
attachment floating system as described in
the following chapters. Practise the use of
the equipment at a sufficiently open area,
where are no obstacles. Using the
attachment when reversi
ng with the loader
is not recommended, as the wheels of the
loader compress the material on the
ground, decreasing the performance of the
vacuum brush.

20 (40)
For the best collecting results, the 2-pump setting on the loader auxiliary hydraulics
control a
nd high engine rpm should be used. Adjust drive speed according to operating
conditions.
To prevent damaging the brush bristles, do not move the vacuum brush on a surface
unless the brush is rotating.
WARNING
Careless operation can injure you or bystanders -
Keep the loader under control at
all times.
Operating a powerful attachment requires the full attention of the operator. Do
not perform distractive actions while mowing, such as using mobile devices.
Recommended operating speed and maximum allowed oil flow:
Adjust engine RPM so that the loader's auxiliary hydraulic flow is within the specified range for the
Vacuum brush. Too little flow will not rotate the vacuum unit rotor fast enough for good results.
However, too high setting will result in excess vibration and noise, and the attachment may get
damaged. Generally, the 2-pump setting and high engine rpm should be used.
Adjust drive speed according to operating conditions to ensure good result. Also, monitor the filling of
the collector box through the transparent plastic window of the Vacuum brush.
Operate the attachment keeping the hydraulic flow within recommended range. Never
exceed maximum allowed input of hydraulic energy.
Stop the Vacuum brush immediately if you notice abnormal noise, vibration, or if the the
collector is blocked. Find out the cause before continuing use.
CAUTION
