2. Designed purpose of use
The AVANT Compressor is an attachment that is suitable for use with AVANT compact loaders that are
shown in Table 1. The compressor is used with means of the auxiliary hydraulics oil flow of the loader, making
it possible to have high output of compressed air near work site even in difficult conditions.
The compressor creates max. 400 l/min air flow at 8 bar pressure. It can be used for running power tools and,
for example, filling of large tyres in places where electric current is not available, and for cleaning of big
machines like combined harvesters etc. If needed, the compressor can be connected to a larger system to
provide temporarily compressed as a back-up compressor.
The Compressor 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
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 locking pins up and turn them backwards into the slot
so that they are locked in the upper position.
If your loader is equi
pped with a hydraulic attachment locking system, see
additional instructions about the use of the locking system from the relevant
manuals.

Make sure that the hydraulic hoses are positioned so that they will not get in
between the coupling plate of the loa
der and the attachment, and that they will
not get squeezed or chafed against sharp edges.
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 (26)
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 m
eter
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. S
tability 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
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 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.

15 (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 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 disc
onnecting 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.

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
Risk of crushing -
Never allow anyone to get under a
lifted attachment or loader boom.
Keep in mind that the
loader boom can be lowered or tilted even if the engine has
been shut down (crushing hazard). The loader is not intended
to be left to keep a load elevated for longer periods. Always
lower the attachment to a safe position
before leaving the
driver's seat.
. ..
WARNING
Burn hazard - Keep clear of hot surfaces.
The surfaces of
the compressor will get hot quickly. Keep clear especially
from the compressor block and keep the attachment clean to
ensure that the cooli
ng system works efficiently. Make sure
that the air flow around the compressor is not obstructed.

6.1 Checks before use
Read all instructions before use. Make sure you have both the Avant Operator's manual of the loader
and attachment, and the Dynaset Operating instructions of the hydraulic compressor available.
Use the Compressor only when the loader is parked and the boom is lowered.
Ensure that during use the Compressor is in upright position.
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.
Check the condition of the compressor, leakages, cleanliness, cooling fan, and oil level. Consult the
Dynaset Operating instructions of the hydraulic compressor, if necessary.
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.
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

18 (26)
6.3 Using the compressor
WARNING
Risk of release of compressed air and equipment damage -
Never exceed the
maximum allowed input of hydraulic oil flow of the compressor. Too high hydraulic oil
flow to the compressor can damage the compressor in a way that compressed air or parts
are ejected from it. Compressor is designed to be run with low input oil flow. Use 1-pump
setting of the loader and keep the engine of the loader at idle RPM. Hydraulic oil flow that
is slightly above the nominal flow will cause increased heat, noise, and wear.
Starting to use the Compressor:
1
Set the attachment to working
position. The Compressor is
intended to be used when it is
lowered on the ground as shown in
the adjacent figure.
2
Check that the auxiliary hydraulics
oil flow is within the recommended
range for the compressor before
starting the compressor.
There are no adjustable settings on
the compressor. Correct operating
speed is adjusted by controlling the
loader engine rpm, to set auxiliary
hydraulics output of the loader to
correct level (23-
25 l/min, see
operator’s manual of the loader).
3
Start the Compressor by turning the
auxiliary hydraulics control lever to
its locking position, or use the
buttons on the joystick. See Dynaset
Operating instructions of the
hydraulic compressor, if necessary.
Correct operating speed:
The speed control valve will compensate excess hydraulic oil flow of about 10-
20 l/min. However, the
maximum input must not be exceeded and the output flow of the loader must be set as correct as possible. If
the loader is equipped with two auxiliary hydrauli
c pumps, using both pumps is possible only when the loader
engine rpm is low.
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 eq
uipment
when another person operates the controls of the loader.
WARNING
Choking hazard -
Ensure ventilation when using a loader with combustion engine
indoors.
Using the loader engine indoors increases, among other things, the carbon
dioxide
level of the air, which affects the safety of the operator. Make sure that ventilation
is sufficient and adapt use periods according to operating conditions.

19 (26)
Unnecessarily high engine rpm will heat up the hydraulic oil, may overheat the
compr
essor, will cause increased noise, and may cause damage or premature wear. Set
the engine rpm and auxiliary hydraulics oil output to correct level for compressor.
. ..
Start the compressor only when it’s in upright position to ensure proper oil circulation
within the compressor. If the compressor has been tilted considerably, allow it to stand
upright for a few minutes before starting it. Avoid tilting the compressor by more than 45
degrees in all situations.
. ..
Overheating of hydraulic oil
decreases power and affects the service life of the hydraulic
components of both the attachment and the loader. Clean the loader oil cooler core
regularly; refer to the loader manual for more instructions. Poorly performing cooler may
cause the hydraulic oil to overheat also in winter conditions.
. ..
During use:
Monitor the operation of the compressor and loader during use. Use compressed air as instructed in the
manual of the specific pneumatic tool. Use correctly sized hoses to minimise pressure losses. Never direct air
jet towards persons or try to hold leakages with hands; pneumatic air can penetrate skin causing life
threatening condition. The compressed air produced by the compressor must not be used as breathing air in
any application. Blowing air towards clothes causes some materials to burn much more easily, using blowgun
to dry clothes is prohibited.
WARNING
Risk of serious injuries -
Never direct air jet towards any person or use the
compressed air as breathing air in any application. Pn
eumatic air can penetrate skin
causing life threatening condition.
. ..
Stopping the Compressor:
Stop the Compressor whenever compressed air is not needed. The compressor is stopped by releasing the
auxiliary hydraulics control lever to its neutral position. The residual air reservoir can be emptied through
manual valve in controlled way. See page 20.
6.4 Transport position
Lift the Compressor off the ground before
transport drive. Keep the loader stable. Always
transport
the attachment as low and close to the
ground as possible. Keep the telescopic boom
retracted during drive.

20 (26)
6.5 Storage
Uncouple and store the attachment on level ground. The best way to store the attachment is a place where it
is protected from direct sunlight, rain, and extreme temperatures.
Avoid leaving the attachment laying directly on the ground. Place it on blocks of wood or on a pallet, for
example.
Place the multiconnector on to its holder as indicated with arrow (1) in the figure below. Never leave the
hydraulic connector on the ground.
Drain the reservoir as instructed below.
Make sure that the attachment is secured against all movements during storage.
Never climb on the attachment.
To ensure the stability of the attachment during storage, lay it down on a pallet so that the quick coupling plate
is easily accessible with the loader, as shown in the figure below.
Relieving compressed air:
The air reservoir can be drained by
opening the manual valve pointed
with arrow (2) in the adjacent figure.
Open the screw slowly and gradually
with fingers so that air is released in
controlled way. When air has been
drained, open the valve more and, if
needed, tilt the compressor to drain
all condensed water from the
reservoir. Tighten the valve using
fingers.
Do not use tools. Wearing
gloves is recommended.
Especially in humid environment or
low temperatures the reservoir must
be drained from condensed water
after each use.
Long-term storage:
Before winter storage, carefully clean
the attachment. Touch up the
paint
where needed to prevent rust
damage.
