2. Designed purpose of use
The AVANT vacuum brush is an attachment suitable for use with AVANT multi purpose loaders shown in
Table 1. The vacuum brush is intended for collecting of tree leaves or other light materials in parks, lawns,
yards etc. The vacuum brush is not suitable for collecting sanding gravel, litter or other heavier materials.
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 broom that loosens more compacted and wet 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 blower unit is equipped with blades to shred the collected material and to
help to avoid blockages. The broom rotation speed can be adjusted steplessly. Additionally, the vacuum
brush can be equipped with one or two side brushes. If only one side brush is used, it can be mounted on
either side of the unit. 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 intended for collecting larger trash or sanding gravel. For
collecting gravel we recommend the Avant Broom with collecting box.
The vacuum broom makes use of the auxiliary hydraulics and lift boom of the loader. The attachment is
operated from the driver’s seat of the loader, and as rule, it should be operated when driving forward. When
in use, the vacuum brush is kept on the ground surface on it’s own support wheels and it must be kept close
to the ground also when transporting it. The front lid of the collector box can be opened electrically, and the
whole emptying operation can be done while sitting on the driver’s seat, by using the boom of the loader to
lift and tilt the attachment to empty it. With the telescopic boom of the loader the collector can be emptied
also on a high platform or a pile.
The attachments have been designed to require as little maintenance as possible. The operator can perform
regular maintenance tasks. The brush parts can be removed for cleaning and they can be replaced if
needed. All maintenance tasks can’t usually be performed by the operator; certain more demanding tasks,
such as service or replacement of the hydraulic components, must be left to qualified professionals.
Appropriate protective equipment and original spare parts must be used for the maintenance. All used spare
parts must be similar to original specifications, which can be ensured by using only original Avant spare
parts.
Read the maintenance and servicing instructions in this manual. Please contact your AVANT retailer if you
have additional questions about the operation or maintenance of the equipment or if you need spare parts or
maintenance services.

3. Safety instructions for the vacuum brush
Please bear in mind that safety is the result of several factors. The loader-attachment combination is highly
powerful, and improper or careless use may cause serious personal injury or property damage. Due to this,
you should carefully familiarise yourself with the manuals of both the loader and the attachment before
starting operation. Do not use the attachment if you have not familiarised yourself with its operation and the
related hazards.
•When attaching the 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.
•The vacuum brush is intended to be used by one operator at a time. Do not go near the
equipment if another person is operating the controls of the loader.
•Keep a minimum safety distance of two metres from the vacuum brush when it is
running. Beware of entanglement and severing hazards of the rotating brushes,
collecting nozzle, and the vacuum blower in particular, and the debris that may be
thrown from the attachment.
•If it is necessary to go near the attachment because of, e.g. blockage, always follow the
safe stopping procedure shown on the next page. Never leave the driver’s seat when
the vacuum brush is running or if the auxiliary hydraulics control lever is locked on.
Keep hands and feet away from moving components. Removing a blockage may cause
the parts to move, if the hydraulic system is pressurized.
•Be sure not to tilt the vacuum brush too far up, when it could tip over onto the boom due
to the movement made possible by the floating system. Use the controls of the loader
slowly and carefully especially when the collecting box is full.
•Always transport the vacuum brush as low and close to the machine as possible to
keep the centre of gravity low and for the best stability.
•Pay attention to the surroundings and any other persons and machines moving in the
vicinity. Pay attention to the contours of the terrain and other hazards, such as
branches and trees reaching the driver's area.
•Never leave the driver’s seat if the attachment is lifted from the ground. Always lower
the vacuum brush on it’s own support wheels before leaving the driver’s seat. Make
sure that the attachment is properly supported for maintenance and inspections. Going
under a raised attachment or boom is dangerous, the boom may lower unexpectedly
due to loss of stability, equipment failure, or other persons using the controls of the
loader.
•When taking the vacuum brush off from the loader, ensure that it is secured against
accidental movement. To prevent the attachment from moving, lower it onto blocks of
wood, for example.
•Make sure that you use only an attachment that is in proper working condition. Perform
daily inspections and read the instructions on service and maintenance. Never use the
attachment if the hydraulic systems of the attachment and the loader are not completely
in order. Check the brushes and the vacuum unit regularly.
•Make sure that the loader is equipped with necessary safety equipment, and that they
are in order. Seat belt must be used. If there are specific risks at the operating area,
such as hazard of falling objects, the loader must be equipped with protective structure.
•The attachment may throw stones or other objects at high speed. Do not use or
transport the vacuum brush while the collector box door is open, or if the collecting
hose is not properly connected.

7(22)
•Stop the equipment as described in safe stopping procedure before performing any
maintenance or adjustments.
•Do not modify the structure of the attachment in a manner that could affect its safety.
The protective covers or the collecting box must be in place when using the vacuum
brush.
•Also read the safety instructions shown in the operator’s manual of the loader.
Safe stopping of the equipment, before going near the attachment:
•Stop the attachment and the loader. Note that full stopping of the vacuum blower may
take several seconds.
•Lower the boom and set the attachment on it’s support wheels.
•Shut down the loader engine.
•Lock the parking brake.
•Release residual pressure from the hydraulic system.
Note that the loader boom moves down and may be tilted even if the engine has been
stopped. Never go under a raised boom or vacuum brush component. Always lower
the attachment on it’s support wheels before leaving the driver’s seat.
Remember to wear proper protective clothing:
•The noise level at the driver's seat exceeds 85 dB(A). Wear hearing protection while
working with the loader.
•Wear safety boots while working with the loader.
•Wear protective gloves and safety goggles when handling hydraulic components. Wear
protective gloves when handling the blades of the attachment.

5. ssembly of the vacuum brush
The vacuum brush is ready for use as delivered. Mount the attachment, its hydraulic hoses, and electric
harness according to the following instructions, and practise its use in a safe area. Read the following
instructions for mounting, using and maintenance of the attachment before starting the equipment.
5 1 Attaching the vacuum brush to the loader
Mounting the attachment to the loader is quick and easy, but it must be done carefully. An attachment that
has not been locked may come off from the loader and cause hazardous situations. In the worst case, the
attachment may slide onto the driver along a raised boom. For this reason, the attachment must under no
circumstances be raised to a height of over one metre when it has not been locked. To prevent hazardous
situations, always follow the attachment mounting instructions provided in the following pages. Also
remember the safety instructions in Section 3 and the instructions provided in the loader manual.
Make sure that the broom will not move when working around it. If necessary, use, for
example, blocks of wood to prevent the moving of the attachment.
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 hydraulic attachment locking system,
see additional instructions about the use of the locking system from the
relevant manuals.
•Ensure that the hydraulic hoses or the electric harness are not in the way
during installation.
Step 2:
•Turn the quick attach plate hydraulically to an obliquely forward position.
The angle between the loader front plate and attachment coupling should
be about as shown in the adjacent picture.
•Drive the loader onto the attachment. If your loader is equipped with a
telescopic boom, you can utilise this.
Step 3:
•Turn the boom control lever left to turn the bottom section of the quick
attach plate onto the attachment.
•Lift the boom slightly – pull the boom control lever backward to raise the
attachment slightly off the ground.
•Lock the locking pins manually or lock the hydraulic locking - do not use
the automatic locking pin release. Always check the locking of both pins.

10(22)
An attachment that has not been completely locked to
the loader may fall on the boom or operator, or under
the loader during driving, and cause serious injuries.
Before moving or lifting the attachment, make sure that
the locking pins are in the lower position and come
through the fasteners on both sides. Never move or lift
an attachment that has not been locked.
Do not use the automatic return of the locking pins to lock the vacuum brush due to
the movement enabled by the floating of the attachment. Excess tilting causes the risk
of toppling over. Lower the attachment onto the ground and secure the locking
manually.
5 2 Connecting and disconnecting the hydraulic couplings
The default connector for hydraulic couplings is the multiconnector system. If you want to change the type of
the hydraulic couplings of the attachment or the loader, contact your Avant dealer or service point for
instructions or installation services.
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.
Keep the couplings 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 multiconnector onto its holder.
Connecting the multiconnector system:
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. 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.
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 any of the couplings 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.
