2. Designed purpose of use
The AVANT Multi function drive unit is an attachment that is suitable for use with AVANT compact loaders that
are shown in Table 1. The strong and robust hydraulically rotated multi purpose drive unit is equipped with
square shaft and pin locking system, which enables to use different work tools. The pin locking system makes
it possible to use different tools on the drive unit, and to change them quickly.
The drive unit can be fitted with the following work tools: augers, screw pile adapter, concrete mixing drum,
screw cone log splitter, screening drum, cable/hose reel, carousel broom and rotary hoe. The available tools
for the drive unit are shown in more detail in this manual.
The Multi function drive unit and its tools are 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

3. Safety instructions for using the multi function drive unit
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 tha
t 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 attach plate are in the lower
position and that they have locked
the attachment to the loader. Never lift or move an unlocked attachment.

This attachment 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 crushing - Make sure that attachment is locked properly. An unlocked
attachment may move or fall over causing
serious injuries. When attaching the
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.
Also make sure that the drive unit tools are securely locked to the drive unit.
Hazard of entanglement - Rotating parts. Never leave the driver’s seat when the
attachment is running or if the auxiliary hydraulics control is locked on, except when
using tools that specifically need to be rotated whi
le staying near the attachment.
Always keep a safe distance between persons and machinery that may start or
move. Stop the equipment following the safe stopping procedure and lower the
attachment firmly on the ground before leaving the driver’s seat, or wh
en other
persons are present at the working area.
Hazard of entanglement - Never wear or allow any assisting persons to wear
loose clothes, such as loose shoelaces, or long scarves when working with or
near the attachment. Always stop the attachment be
fore anyone gets near it. Keep
hands and feet away from moving components. To eliminate the risk of entanglement
at the work site pay attention to proper clothing.
Risk of tipping over - Survey the operating area and plan work ahead. Make
sure in advanc
e that it is safe to work at the operating area. Ensure the stability of the
loader and firmness of ground also on even terrain.
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 l
oss of
stability, mechanical fault, or if another person operates the controls of the loader.

WARNING
Risk of tipping over - Always transport the attachment as low and close to the
machine as possible to keep the centre of gravity low. On slippery surfaces drive
slowly and deliberately. Operate the controls of the loader slowly and calmly
especially on inclined terrain.
Note that the drive unit is hinged and moves freely. When transporting, the drive unit
must be tilted forward and locked with locking pin.
Do not tilt the drive unit up
excessively, as it could tip over. Keep the axle pointed towards the ground in a
position where the axle will not swing or hit the loader, ground, or any obstacle.
The loader can move slightly caused by the oscillating motion of rotating tool, make
sure that moving will not cause hazards. Do not press the loader boom down too
hard, and keep front tyres in contact with the ground.
Make sure that the attachment is properly supported for maintenance and
inspections. Store
the tool properly and make sure that the drive unit is supported
before removing the locking pin of the angle adjustment of the drive unit. Never
perform any maintenance or adjustments, or change drive unit tools, while the loader
engine is running.
Use the attachment only for its intended use and only with original tools on the
attachment.
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 and 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. Do not modify the
attachment in any way that could affect its safety.
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.
DANGER
Risk of serious injuries from rotating parts -
Keep safe
distance. Entanglement around the rotating tools or
getting crushed under the loader
boom can cause
serious injuries or death.
Do not leave the driver’s seat
while the attachment is in operation, or when it is lifted off
from the ground, unless using tools that are specifically
intended to be used while staying near them. Also, keep
other
s at a safe distance from the equipment and stop the
attachment immediately latest when there are others closer
than 1 meter from the attachment. Follow safe stopping
procedure when going near the attachment or when changing
tools.

10 (66)
DANGER
Risk of entanglement and crushing -
Stop the attachment before cleaning or
removing blockages.
The attachment can start to rotate immediately after a blockage is
removed. Always follow the safe stopping procedure to prevent all rotating parts from
moving when clearing a blockage.
. ..
DANGER
Risk of cutting and severing -
Sharp edges and severing
points on work tools.
Beware of the sharp blades and risk
of crushing especially during maintenance or when removing
blockages. Always stop the attachmen
t by following the safe
stopping procedure. To make sure that the attachment will
not rotate, disconnect the multiconnector (or hydraulic quick
couplings) before going near it. Note that the loader boom
moves down and may be tilted even if the engine has b
een
stopped. Never go under a raised boom or any component of
the attachment. Keep away from the moving linkage.
Remember to wear proper personal protective equipment:
The noise level at the driver's seat may exceed 85 dB(A) depending on loader
model and operating cycle. Extended exposure to loud noise can cause
hearing impairment. Wear hearing protection while working with the loader.
Wear protective gloves.
Wear safety boots whenever working with the loader.
Wear safety glasses e.g. when handling hydraulic components.

Handling some types of materials materials can cause spreading of dust.
Protect yourself from dust with a respirator mask.
