2. Designed purpose of use
The AVANT Carousel broom is an attachment suitable for use with AVANT multi purpose loaders, as shown in
Table 1. The Carousel broom sweeps the material from floors and other hard surfaces efficiently aside,
without the need to sweep the same location many times.
The Carousel broom can be turned manually to both sides by max. 57 degrees (1090 mm), which allows
brushing next to walls also. The side shift has multiple possible setting points. The direction of rotation of the
attachment can be selected freely. The Carousel broom is equipped with replaceable nylon brush. The broom
can be rotated in either direction with the auxiliary hydraulics of an Avant loader.
The Carousel broom 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.

3. Safety instructions for using the attachment
Please bear in mind that safety is the result of several factors. The loader-attachment combination is highly
powerful and improper or careless use or maintenance may cause serious personal injury or property
damage. Due to this, all operators must carefully familiarise themselves about correct use and the operator's
manuals of both the loader and the attachment before starting operation. Do not use the attachment if you
have not completely familiarised yourself with its operation and the related hazards.
DANGER
Misuse, careless use
, or using an attachment that is in poor condition, may
cause risk of serious injuries.
Familiarise yourself with the controls of the loader,
correct coupling procedure, and the correct way 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 a
ttach plate are in the lower position and that they have locked
the attachment to the loader. Never lift or move an unlocked attachment.

The Carousel broom is designed to be used by one operator at a time. Do not let
others near the danger area of the equipment when it is in use.

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 of injuries from abrasion, friction, entanglement - Stay away from
rotating broom.
Never leave the driver’s seat when the broom is running or when
the auxiliary hydraulics control lever of the loader is locked on. The hydraulically
operated broom is strong and it has very high torque that will keep the broom
rotating. Keep a safety
distance of at least 5 metres from activated broom. Keep
hands and feet away from moving parts. The bristles of the broom can cause skin
injuries even from light contact with any body part.
Beware of entanglement and severing hazards and possible debris thrown by the
broom.
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 attachment 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.
Beware of the crushing hazard of the moving broom shaft, always lower the broom
completely, or use appropriate supports, if it is necessary to handle the broom while
lifted.
Do not tilt the broom too much upwards. The broom is hinged in a way that allows the
b
room to follow the contours of the terrain. When tilted excessively, the broom may
tilt on the loader boom and may reach the driver’s zone. Always keep the broom
close to the ground.
When unlocking the broom from the loader, ensure that the broom is secured against
accidental movements. To prevent the attachment from moving and the broom from
getting damaged, use the support stand on the broom. If necessary, lower the
attachment onto blocks of wood, for example.

Shut down the loader and place the attachment to a safe position as shown in Safe
stopping procedure before any cleaning, maintenance, or adjustments.
Pay attention to the surroundings and any other persons and machines moving in the
vicinity. Pay attention to the contours of the terrain an
d other hazards, such as
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 a
ttachment 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.

5. Attaching 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 betw
een 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 t
he 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 o
f 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.

13 (26)
WARNING
Risk of crushing - Avoid tipping over the attachment. Excess
ive 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 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 atta
chment, 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
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 c
ontrol 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 i
njuries or burns. Follow safe stopping procedure
before disconnecting hydraulics.

14 (26)
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 d
ifficult. 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 mult
iconnector 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 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
un
locking 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.

6. Using the broom
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. Practise the use of the
attachment and its controls in an open and safe area. If you are unfamiliar with the loader in use, it is
recommended to practise its use without any attachments.
WARNING
Entanglement hazard -
Never leave the driver’s seat
when the broom is in operation
. Keep a safe distance
between the broom and other persons and stop the broom
and lower it down completely whenever others
are in
proximity with the broom. Never perform any maintenance or
adjustments if the broom can start by accident. Shut down
the loader engine, turn off auxiliary hydraulics and lower the
loader boom before going near the attachment.
WARNING
Hazard of thrown objects - Keep bystanders away. Note
that the attachment can throw stones, gravel, or other objects
found in the area at high speed. Always keep a safety
distance of at least 5 metres to other persons.
6.1 Operator qualification
Anyone who intends to use the attachment must:
Know the intended use of the attachment.
Know how to use the loader safely in different operating conditions.
Read and always follow the instructions concerning the use of the attachment in this operator's
manual.
Have this manual and the operator's manual of the loader available.
Ensure that the loader and the attachment are used in a safe manner and as intended.
Never 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.
Complete any possible mandatory training required by the employer before use.

16 (26)
6.2 Checks before use
Before starting work, remove large items that can’t be collected with the broom from the working area.
Drive carefully on uneven terrain and note the effect of heavy load at the front of the loader to the
stability and handling of the loader.
Before each use, check the operation of the broom and ensure that the brush can rotate freely. Check
that there is no string or other foreign material coiled around the broom.
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.
Regularly clean the loader oil cooler core; refer to the operator's manual of the loader for
more instructions. Overheating oil decreases the power and affects the service life of the
hydraulic components of both the attachment and the loader.

17 (26)
6.3 Operating the broom
To rotate the broom:
Move the auxiliary hydraulics
control lever of the loader towards
its locking position (or use the red
button of the electric joystick) to
rotate the broom
counterclockwise.
Stop the attachment by releasing
the lever to neutral position.
Move the auxiliary hydraulics
control lever of the loader to
reverse direction to rotate the
broom clockwise.
Stop the attachment by releasing
the lever to neutral position.
Check the position of the storage support before using the attachment. Always lift the
storage support (tilt backwards) before using the broom. See instructions in this manual.
Correct operating position
Before starting the broom, place it to the working position:
1. The Carousel broom works in the most efficient way, when it is kept tilted in slightly forward tilted
position, as shown in figure below. It is important to keep the broom in tilted position in order to swipe
material efficiently.
2. Tilt the quick coupling plate forward, so that the broom can float. See more information about the
floating system in this manual
When a suitable position is adjusted, lift the loader boom by operating the boom control lever only
longitudinally. In this way, the correct position is maintained, when lowering the attachment.

18 (26)
If your loader is equipped with a telescopic boom, you can utilize it for a better view to the working area.
Set the loader engine rotating speed according to the material being handled and operating conditions.
Moderate engine rpm are usually enough to rotate the broom adequately so that the broom sweeps the
material neatly to its side. On 600- and 700-series loaders one or two working hydraulic pumps may be used
according to operating conditions. High rotating speed will wear down the brush more quickly and typically it is
not necessary to use high rotating speeds.
To prevent damaging the bristles, do not drive with the loader keeping the broom on the
ground without rotating it.
Operate the attachment keeping the hydraulic flow within recommended range. Never
exceed maximum allowed input of hydraulic energy.

19 (26)
6.4 Floating mechanism
The Carousel broom is equipped with a mechanical floating system, which allows the broom to follow the
contours of the terrain without moving the loader boom. For the best performance of the broom, it is important,
that the floating is set correctly on an even surface.
The hinged boom of the Carousel broom allows the broom to lift and therefore it prevents pressing the brush
too hard against the ground. The floating of the loader boom (optional equipment for loaders) is not required
for using the carousel broom and it should be switched off.
Setting the floating:
On even surface adjust the position of the
loader boom and its quick coupling plate so the
rear of
the broom is held supported by the
loader boom. The rear part of the broom
should be at clearly higher level than the front.
Note that tilting the broom too much forward
decreases the effective area of the broom,
hindering the work performance.
If the broo
m is set in parallel with the
ground, it will not sweep material to its
side, but the rear of the brush rotates
material around.
Do not use extra weight on the broom to ensure long service life of the brush.

20 (26)
6.5 Broom side shift
The carousel broom may be turned to sides to making it easy to brush near the walls. There are multiple
possible side shift positions; the figure below illustrates the extreme positions (± 57 degrees).
Fit the pin through one of the three holes on the broom beam and one of the five holes on the broom frame.
To make the adjustment easier, tilt the loader quick coupling plate forward.
Before operating the broom, ensure that the side shift has been correctly locked with the
pin, and that the hydraulic hoses are not in contact with the brush.
. ..
6.6 Transport position
CAUTION
Keep the loader stable. Always
transport the collecting broom as
low and close to the ground as
possible. Keep the telescopic boom
retracted during drive.
