2. Designed purpose of use
The AVANT Ice rink scraper blade is an attachment suitable for use with AVANT multi purpose loaders, as
shown in Table 1. The articulated Ice rink scraper blade is intended for maintenance of ice hockey and skating
rinks only. The curved blade of the attachment moves the material efficiently to the side. The attachment is
equipped with a roller pad, which helps cleaning the ice in front of walls and corners also. The roller pad is
mountable on both sides of the attachment.
As standard, the attachment is equipped with hydraulic slewing, which enables to choose the side to which the
material will be transferred without interrupting work. The blade has large 3000 mm working width and it can
be turned hydraulically to both sides by max. 30 degrees. The blade edge is a thin steel plate that will scrape
snow and ice shavings from the surface of a flat, maintained skating surface.
The Ice rink scraper blade 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 Ice rink scraper
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 contro
ls 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 attach plate are in the lower position and that they have locked
the attachment to the loader. Never lift or move an unlocked attachment.
The Ice rink scraper blade 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 impact from sudden s top - Never plow at high speed unless you can be
sure that there are no obstacles at the working area. The loader may stop
suddenly ifit hits an obstacle.Remember that there may be hidden
obstructions or fragile surfaces under the snow. Always use seat belt and drive with
caution.
Pay attention to the surrounding sand 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 that can reach to the driver's area, loose rocks, and slippery
surfaces.
Operate only at well lit areas. Make sure that alllights of the loader are in good
condition, clean, and adjusted correctly. Extra work lights are recommended for the
loader when operating during dark. Mark any obstacle at the work area before
plowing to avoid collisions.
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 islifted. Going under a raised
attachment or loader boomisdangerous, asthe boom may lower due to loss of
stability, mechanical fault, or if another person operates the controls of the loader.
Shut down the loader and plac e the attachment to asafe position as shown in Safe
stopping procedure before any cleaning, maintenance, or adjustments.
Risk of crushing of fingers - The floating attachment bracket allows the blade
to move, creating pinching points near the coupling plate. When coupling the
attachment, maintenance work, and whenever going near the coupling plate of the
loader, keep in mind that the blade can move relative to the coupling plate. Keep
hands away from moving parts.

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. Mou
nt 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 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 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.

13 (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 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 attachment, and compatibility of loader co
ntrol 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 sy
stem 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 (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 hangin
g 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 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
unlocking the quick attach plate, to pre
vent 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.

15 (26)
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.
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
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.
The Ice rink scraper blade is intended only for maintained skating areas. It is not
intended for general snow clearin
g work, and should not be used at any other area
than smooth, maintained ice surfaces. The attachment will get damaged if it is
used for general snow clearing work at other areas.
Many other Avant attachments are available for clearing of snow from, for example, roads
or yards. Contact your Avant dealer for more information about the best solution for other
areas that ice rinks.
WARNING
Risk of collisions - Ensure good visibility.
Never lift this attachment to a height where
visibility from the drive
r's position is obstructed. Ensure unobstructed visibility to all
directions. Keep all windows clean and free of dirt, ice, snow etc.
WARNING
Risk of collisions - Check the operating area before using the equipment. Make
sure that there are no hidde
n obstacles under the snow, for example. Running into an
obstacle may stop the machine suddenly and unexpectedly, regardless of the blade
floating system.

16 (26)
6.1 Checks before use
Check that all obstacles, including any possibly hidden ones, have been removed from the working
area or marked visibly before operation.
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.
WARNING
Risk of injuries related to sudden stop - Drive slow and always stay
alert for
possible obstacles.
For the safety of the operator, the blade is equipped with safety
mechanisms to reduce the risk of sudden stopping of the machine and the possibility of
injuries that could follow. However, the existence of the safety features
will not replace
operator's responsibility. Careful and cautious operating are essential for safety. Any
safety feature by itself will not guarantee safe operating of the plow. The performance of
the safety features may be hindered in certain conditions,
such as packed snow or ice, or
when reversing with the loader.
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; re
fer to the loader manual for more instructions. Poorly performing cooler may
cause the hydraulic oil to overheat also in winter conditions.

17 (26)
6.2 Operating the Ice rink scraper blade
For the best performance of the Ice scraper blade, set the attachment to correct working position:
1.
Place the blade on ice so that the blade edge
rests on the ice firmly at a small angle
2.
When the blade is lowered on the ice, lower the
boom slightly more, so that the floating system
of the attachment allows the blade to move. See
the
following page for instructions about the
floating system.
3.
As a general rule, the attachment should be
adjusted so that the quick coupling plate of the
loader is in upright position. Depending on
specific circumstances at your work area, you
may try to ti
lt the blade a little to front or back.
The vertical position of the attachment will affect
the outcome and accuracy of ice scraping.
The blade should not be pressed hard against the ground as this will affect the handling of the loader, as the
front wheels of the loader begin to lift from ground surface. Avoid pressing the plow hard against the ground to
prevent damaging the plow or its blade.
Blade controls:
Move the auxiliary hydraulics
control lever towards its locking
position (or use the
electric
buttons of the joystick) to turn
the blade right.
The lever should not be left to
the locking position.
Move the lever away from the
locking position to turn the blade
left.

18 (26)
6.3 Blade floating
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.
Floating modes of the Ice scraper blade:
The floating system of the Ice rink scraper blade allows the blade to float vertically and sideways, which
makes working on uneven surfaces considerably easier and more efficient. Depending on the setting of the
blade, the Ice rink scraper blade can be used in the following operating modes:
Freely floating setting: the blade can move up and down, and also tilt sideways
Sideways tilting only, the up and down floating movement can be blocked
Rigid mode: floating movements are prevented.
Floating is set with pins, which are stored on the frame of the attachment:
Freely floating mode:
Blade is in freely floating mode, when both
pins (X) are not fitted, and they are stored
on the frame of the attachment.
Locked modes:
Place the pins to either locking mode,
and
secure with cotter pins:
a Sideways tilting mode (A)

Place pins through the vertically
aligned holes to lock the blade from
moving up and down.
b Fully locked mode (B)

Place the pins to holes on the
sides. The blade must be against
the ground, so that the
pins can be
inserted.

19 (26)
Note that the loader can stop unexpectedly when hitting an obstacle. The boom floating
will not prevent sudden stops or possible damages to the attachment resulted by hitting
an obstacle. Ensure the safety of the operating a
rea before using the equipment and
always fasten the seat belt.
6.4 Blade edge plate
The standard, high strength blade edge provides good performance for general use on maintained skating
surfaces. It scrapes and shaves e.g. packed snow from ice rink easily.
Depending on use, the edge plate wears during use. Always replace worn or damaged edge plate before the
frame of the plow is in contact with the ice surface.
Never operate the attachment without any blade edge fitted, or if the blade edge is too
worn. The attachment may get easily damaged if operated without any blade edge.
. ..

20 (26)
6.5 End plate and roller
The Ice rink scraper is equipped with an end
plate and roller at one end of the plow. The
end plate helps to collect material from near
the walls
of ice rink. It prevents spilling of
material from the plow.
If necessary, the end plate and roller can be
easily installed on the other side of the plow.
As shown in the adjacent figure, the end plate
and roller are installed with four screws and
wing nuts.
6.6 Transport position
CAUTION
Keep the loader stable. Always
transport the attachment as low and
close to the ground as possible.
Keep the telescopic boom retracted
during driving.
