2. Designed purpose of use
The AVANT Snow blower 1150/1500 is an attachment that is suitable for use with AVANT multi purpose
loaders which are shown in Table 1. The Snow blower is especially suitable for use when it is preferred to
spread snow evenly to the sides of the area instead of piling it up. The two-phase snow blower is suitable also
for professional use, and it is equipped with a powerful hydraulic system with two separate hydraulic motors
for efficient operation even when handling wet and heavy snow.
As standard, the snow blower chute can be turned electrically by 260 degrees directly from the driver’s seat.
The wide adjustment range of the manual throwing height control makes it possible to control the ejection of
snow precisely as needed, either as to pile snow directly to the side of the drive path, or to spread evenly far
away. As an option, electric throwing height adjustment is also available, which can be operated only with the
optional electric attachment control switch pack of the loaders.
The Snow blower 1150/1500 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.

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 d
o 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 t
he
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 overl
oad 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 inclu
de 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 auxilia
ry 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.

14 (32)
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 signi
ficantly 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 conn
ector. 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 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 coup
lings before
unlocking 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.

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. Practise the
use of the attachment and the controls of the loader in a safe area. If you are unfamiliar with the
particular loader model, it is recommended to practise its use without any attachments.

WARNING
Make sure that the discharge chute guard is locked in its place before operating
the snow blower. Using the snow blower without the guard in i
ts place is prohibited.
Ensure that the chute is directed towards safe direction before starting the snow blower.
Operate the manual throwing height adjustment only when the attachment is stopped.
. ..
Overheating of hydraulic oil decreases power a
nd 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.

6.2 Use
Using the snow blower:
1. Set the attachment to working position. The snow blower works in the most efficient way, when it is
tilted slightly forward, or when it is kept lightly on the ground in upright position, as shown in figure
below. In this way, the edge plate of the snow blower collects e.g. less sand.
NOTE: The attachment is intended to run on its side skids.
2. The snow blower is started by turning the auxiliary hydraulics control lever to its locking position, or by
using the buttons of the joystick. Start the attachment at the driver's seat when using low engine rpm
on the loader.
During operation, use high engine rpm and slow drive speed adjusted according to operating
conditions.
The snow blower requires high output of hydraulic oil. Depending on the loader model, typically the 2-
pump setting of auxiliary hydraulics and high engine rpm should be used for most effective discharge
of snow.
3. Do not press the snow blower too hard against the ground, as it would affect the controllability of the
loader, as the front wheels of the loader tend to lift off from the ground.
If your loader is equipped with boom floating system, it should be switched on after the Snow blower
is set to its correct working position.
Do not use the snow blower to push the snow. Make sure the rotor is on.

Boom floating (optional equipment on some loader models)
If your loader is equipped with the boom floating option, it is recommended to switch it on. Floating allows the
blade to follow the surface of the ground more effectively, improving its performance.
Note that the loader can stop unexpectedly if the attachment hits an obstacle. The boom
floating will not prevent sudden stops or possible damages to the attachment resulted by
hitti
ng an obstacle. Ensure the safety of the operating area before using the equipment
and always fasten the seat belt.
Auger protection valve
The snow blower is equipped with a function that will stop the auger when the force needed to rotate it
becomes excessively high. The purpose of the feature is to prevent damaging the auger when i.e. a large
block of ice or a foreign object enters the snow blower.
The attachment will start immediately after the blockage is cleared. If the snow blower stops during use, stop it
by following the safe stopping procedure and check the equipment. The safety feature will not affect the
normal operation of the snow blower. Contact service to check the operation of the system if necessary.
Adjusting the hydraulic system of the attachment is allowed only for authorized Avant service.
6.3 Using the electric functions of the Snow Blower
1.
A cable harness with a 2-way switch is delivered with the attachment.
Hold the switch towards either direction to turn the discharge chute.
This sepa
rate electric harness with a switch can be used only to
control the electric chute rotation.
See page 15
for instructions about how to connect the electric
harness of the attachment.
Select the location of the switch in the cab so t
hat it is easily
accessible but will not be used inadvertently.
2. Alternatively, when the loader is equipped with the optional
Attachment control switch pack, it can be used to control the
discharge chute rotation and throw height of the snow blower.
See page 15
for instructions about how to connect the electric
harness of the attachment.
The discharge chute rotation is controlled by switch number 2 and
the throwing height with switch 3. Switch number 1 is not in use with
the snow blower.
