2. Designed purpose of use
The AVANT Tipping trailer is an attachment that is suitable for use with AVANT compact loaders that are
shown in Table 1. The trailers are intended for transporting and dumping of loose materials, such as soil or
sand.
The indicated load capacities, safety instructions, and recommendations for use must be observed when
using either trailer model. Both trailer models are equipped with hydraulic dumping, which makes it possible to
empty the trailer from the driver’s seat. The attachment requires a ball hitch and double-acting hydraulic rear
outlet from the loader.
The sides and rear hatch can be opened, and they can be removed, if necessary. When removed, the base of
the trailer bed is completely flat. For transporting lighter materials, an extra side kit can be fitted to increase
the volume of the smaller trailer quickly and easily. The larger trailer model has side extensions as standard.
Extending the sides with other types of side extensions is prohibited.
The tipping trailers are intended to be fitted only to Avant loaders or to other sufficiently robust garden tractors
or all terrain vehicles. The trailers must not be coupled to cars or tractors, and they are not suitable for road
use. Find out about the applicable regulations and restrictions before using the trailer on any road area.
The Tipping trailer 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 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.
Familiarise yourself with the manual's instructions regarding service and maintenance. Please contact your
AVANT dealer if you have additional questions about the operation or maintenance of the equipment, or if you

3. Safety instructions
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
DANGER
Risk of serious injuries - Ensure positive locking of the trailer coupling. An
unlocked trailer can move uncontrollably and cause serious injuries -
Always make
sure the trailer coupling is positively locked. Couple the trai
ler only to a correctly
sized tow hitch.
WARNING
Risk of tipping over - Lower the bed before leaving the driver’s seat. A trailer
may tip over, especially when its bed has been lifted. Never leave the driver’s seat
when the trailer is tipped. If the ma
terial does not slide from the trailer when tipping,
lower the bed before trying to assist to empty the trailer with other means. Do not
shake or twitch the trailer when it is tipped.
Risk of crushing - Never leave the trailer bed to lifted position. Keeping the
trailer lifted causes a risks of loss of stability and crushing in between the bed and
frame of the trailer. Keep the bed lowered to its lowest position and utilize the tipping
function only at the final emptying spot. Driving while the bed is li
fted is prohibited,
except when moving short distances while emptying the trailer. The trailer bed must
not be left to lifted position.
Risk of tipping over - Avoid overload. A load that is too heavy for the operating
conditions hinders the controllabil
ity of the loader. The maximum stated capacity can
not be regarded as the maximum safe load. The load must be adapted to the
operating conditions and also with the loader model in use. The warranty does not
cover for damages caused by overload.
Uneven load may cause loss of stability or hinder the controllability of the loader.
Load the trailer as evenly as possible both laterally and longitudinally. Make sure that
enough load is applied on the drawbar and the trailer hitch of the loader; the drawbar
load must never be negative.
Moving of the load on trailer may affect the balance of the trailer and the
controllability of the loader. Keep the load stable.
The loader and the trailer may start to move when parked on a slope or during
loading. Always p
ark the trailer on an even platform and make sure that the trailer is
supported adequately, regardless of being hitched to the loader or standing
independently.

5. Assembling the attachment
Hitching the Tipping trailer is quick and easy, but it must be done carefully. A trailer that becomes separated
may slide or swing hitting the operator or other persons. To avoid hazardous situations, always follow the
following instructions for hitching. Also remember the safety instructions in this manual and in the operator’s
manual of the loader. Coupling or uncoupling should only be done on level ground to avoid possible sudden
movements of the trailer.
Connecting the trailer to the hitch ball:
1. Drive the loader as close
to the tow bar of the
trailer as possible.
2.
Lift the drawbar by turning the handle on the
jack clockwise as necessary. When the
coupling is aligned with the hitch ball, lower the
coupling on the ball while keeping the handle
lifted.
3. Make sure that the trai
ler locks on the hitch
ball. On the side of the towing hitch, there is an
coloured indicator with red and green markings
on it. When the trailer is locked, the arrow
marker should point to the green area.
4.
Turn the supporting jack all the way up and lift
the jack assembly up with the pin locks.
DANGER
Risk of serious injuries - Ensure positive locking of the trailer coupling. An
unlocked trailer can move uncontrollably and cause serious injuries -
Always make sure
that the trailer coupling is positively locked. Couple the trailer only to a correctly sized tow
hitch.
Keep the trailer towing hitch and the hitch ball clean. Do not let the towing hitch to lay against the ground;
always use the trailer support jack. If the attachment is not mounted properly, it may detach from the loader
and cause a hazardous situation. The loader must not be driven if the attachment has not been fixed properly.
Make sure that the ground surface can carry the load. Place extra plates under the jack
as necessary.
WARNING
Crushing hazard -
Never allow anyone to get between the loader and Tipping
trailer.
Between the trailer and the loader there is a risk of crushing. The trailer or the
loader may move unexpectedly. In addition, the drawbar of the trailer ma
y swing
suddenly. Hitch and remove the trailer only on level surfaces and make sure that the
parking brake of the loader is engaged. Use chocks to keep the trailer stationary, if
necessary.

14 (28)
WARNING
Crushing hazard - Support the Tipping trailer prope
rly when loading or unhitching.
A loaded trailer may swing or move abruptly when unhitching it. A heavy trailer that starts
to move can not be controlled manually. Due to this, the supporting of the trailer must be
taken care of when loading or unhitching
the trailer. The trailer bed must be lowered
completely when hitching the trailer or taking it off from the loader.
5.1 Connecting and disconnecting hydraulic hoses
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.
Conventional quick couplings
(alternative couplings for some loader models):
Before connecting or disconnecting the standard quick couplings, the
residual pressure must be released as shown below. The conventional
quick couplings will not connect, if there is pressure in the hydraulic
system.
To connect and disconnect the standard couplings, move the collar at the end of the female fitting. The hoses
should be connected so that the fitting equipped with a coloured cap is connected to the corresponding fitting
of the loader. Note that the protective caps on the loader and the attachment can be fastened to each other
during operation to reduce the accumulation of dirt. When disconnecting the standard quick couplings a small
amount of oil may drip from the couplings. Wear protective gloves and have some cloth at hand to keep the
equipment clean.
When uncoupling the attachment, always disconnect the hydraulic couplings before
removing the trailer hitch, to prevent hose damage and any oil spills. Reinstall the
protective caps on
the fittings to prevent water, dirt, and other 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. Operating the attachment
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
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 compatibili
ty 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 pa
rts. If your loader is not listed in Table 1 on
page , ask your Avant dealer before using this attachment.
WARNING
Avoid running over persons - Check surroundings before driving. Always look in the
direction the loader is moving. Before reversing, al
ways ensure that bystanders,
especially children, are at a safe distance to avoid back-over accidents.
6.1 Checks before use
WARNING
Risk of crushing - Make sure that the Tipping trailer is safe to use.
Check that the trailer is hitched properly. Check also that the fitting of the hitching
on the loader is in order.
Check that air pressure of the trailer wheels is suitable.

Check the drawbar and the locking mechanism of the trailer regularly. Read the
instructions about maintenance and service on chapter 7.

Avoid overloading the trailer. Use the table 5, shown below, to estimate the
weight of the load. Adapt the load according to the loader model and operating
conditions.
Do not use the trailer to transport persons or as a working platform.
Familiarise yourself with the instruction manuals before starting to use the equipment. The operator
must be familiar with the properties of the Tipping trailer, know the maximum load and safety
requirements. Ensure that the loader and attachment are used in a safe manner and as intended.
Remember to lock the parking brake of the loader.
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. Do the daily checks of the loader, see the operator's manual of the loader. 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

16 (28)
The information shown in Table 5 can be used to estimate the weight of the load and to avoid too heavy loads.
The values shown in table are intended to serve as general guidelines. Actual material densities may vary
greatly according to factors such as moisture content, grain size, and compactness of the material.
Table 5 - Typical material densities
Material Density of material, (indicative),
kg / l (t / m³)
Snow 0,2 - 0,8 Example:
Tip
ping trailer A2949 (volume 0,48 m³) is filled with
soil up to its sides (single sides).
The weight of the load depending on to the actual
density of the material, is roughly between 0,48 *
1,5 = 0,72 (720 kg) and 0,48 * 1,8 = 0,864 (870
kg).
The load carr
ying capacity must be estimated by
taking in account the compactness and moisture
content of the material and the evenness of the
load.
Wood chips 0,15 - 0,3
Wood pellet ~ 0,65
Peat 0,4 - 0,7
Soil 1,5 - 1,8
Gravel 1,7 - 1,9
Sand 1,5 - 2
Concrete, dry 1,7 – 2,5
Crushed rock 1,65 - 2,6
WARNING
Risk of crushing -
Ensure that the parking brake of the
loader is engaged when working near the attachment.
Use additional blocks if needed. Whenever possible, lower
the attachment firmly on the ground.
DANGER
Tipping over hazard - Keep the operating area of the trailer clear.
The possibility of
tipping over of the trailer and the movements of the trailer cause a risk for serious
personal injuries or death. Make sure that there are
no other persons at the operating
area of the trailer. Do not allow others to stay near the sides or behind the trailer, keep at
least a safety distance of 3 metres. Stay away from the crushing hazard area between
the trailer and the loader.
WARNING
Risk of serious injuries -
Make sure that enough load is applied on the loader hitch.
Make sure that enough load is applied on the trailer drawbar and on the loader hitch. The
drawbar must not be lifting (negative), because in this case the controllabili
ty of the loader
may be severely hindered. Also the suddenly lifting drawbar may hit the operator when
taking the trailer off from the loader.

17 (28)
6.2 Use
Set the attachment to working
position by locking the trailer to
the hitch coupling. When
transporting lo
ad with the trailer,
make sure that the load is well
balanced and stays firmly. The
load must be transported calmly,
and the swinging of the load must
be avoided.
Always drive slowly while
operating the Tipping trailer.
Adjust the drive speed according
to
the operating conditions and
the ground.
Avoid sharp turns while operating the Tipping trailer.

18 (28)
6.2.1 Opening and removing the sides
After opening the locking of the
sides, the plates can be removed
by lifting them straigth upwards.
Keep the sides a
ttached and
locked always during transitions.
Extra extending of the sides is
prohibited.
.

19 (28)
6.2.2 Tipping the trailer
Use the tipping function only from the driver’s seat and only at the final emptying area. Verify that tipping is
safe by checking the terrain inclinations and by keeping others at a safe distance away from the equipment
due to the overturning risk of the trailer.
Open the rear hatch of the
trailer before activating the
tipping.
Select the 1-
pump setting of
the auxiliary hydraulics of
the
loader.

Use the manual lever to
operate the rear auxiliary
hydraulics, do not use the
electric buttons of the
joystick.

Lift the trailer bed slowly and
calmly.

When the trailer bed is lifted,
avoid shaking the trailer.
Lower the trailer bed before leaving the driver’s seat and always immediately after emptying it. If there is air
trapped in the hydraulic system of the trailer, the bed may twitch while lowering. The system will de-air itself
during normal use.
WARNING
Trailer can tip over when it is in tipping position -
Keep other persons at safe
distance.
Never allow anyone to stay on either side of the trailer when dumping loads
with the loader. Never dump on inclined surfaces.
6.2.3 Operating the rear hydraulic outlet of the loader
Control of the rear hydraulics varies according to the loader model and the implementation of the rear
hydraulics. See the operator's manual of the loader for more information.
DANGER
Tipping over hazard - Do not use tipping function if there is a risk of overturning.
When using the tipping, the trailer may overturn, because the centre of gravity raises
high. Also a strong crosswind may affect the balance of the trailer. When tipping the
trailer, the ground must be laterally level and flat. Make sure that oth
er persons remain at
safety distance, at least 3 metres from the trailer, because of the risk of overturning of the
trailer. The tipping must not be used in case there is a risk of overturing.
WARNING
Risk of serious injuries - Never use the tipping
function when the overhead
clearance is not sufficient.
Hitting obstacles, such as tree branches, parts of buildings,
or low-
hanging live wires may cause serious hazards in addition to the tipping over
hazard. Make sure that overhead clearance is sufficient when tipping the trailer.

20 (28)
Avoid hazards of crushing and fallling of materials by opening the rear hatch of the trailer
before using the tipping function. Lower the trailer before trying to assist to move the
material on the trailer.
Sudden
twitches or swings affect the balance of the trailer when tipping. Do not use the
electric joystick buttons to control the tipping. Drive calmly with loader, avoiding sudden
change in speed or twitches. Move the rear hydraulic control lever calmly with sm
all
movements and low engine rpm. Do not try to loosen material from the trailer by swinging
the trailer with the tipping function or with driving the loader.
6.2.4 Lifting the Tipping trailer
When lifting the Avant Tipping
trailer with an overhead cra
ne, for
example, use three lifting slings
that are approved for lifting
purpose.
Loop the lifting slings around the
axle and hitch coupler as shown
in the adjacent figure.
Alternatively, use Avant Tie down
brackets A423091, if possible.
Make sure that the
lifting slings
cannot move and that the Tipping
trailer doesn't swing during lifting.
Also make sure that the slings
are not tied or get damaged by
sharp corners, for example.
