2. Designed purpose of use
The AVANT Log splitter 650 is an attachment that is suitable for use with AVANT compact loaders that are
shown in Table 1. The attachment is intended to be used for splitting firewood, especially larger logs. The Log
splitter 650 is intended to be used by one person at a time straight from the operator's seat.
The splitting is operated by a hydraulic cylinder, which presses the wood against the splitting wedge. The
splitter returns the cylinder after the wood has been split. The height of the splitting wedge is adjustable to split
the wood into halves instead of quarters. Hydraulic adjustment A443834, as well as 6 way blade A443782 for
larger logs are available as options.
The Log splitter 650 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.

3. Safety instructions for using the attachment
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
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 t
o keep the centre of gravity low,
and keep the telescopic boom retracted during driving.
Risk of crushing - The log splitter must be used by only one operator at a time.
Always keep in mind that the strong cylinder and sharp splitter blade can cause
se
rious injuries if not handled properly. The operation of the log splitter creates a
crushing hazard; do not let others near the attachment when it is in use. Keep a
safety distance of minimum of 10 meters.
Risk of injuries from flying debris - Strong splitter operates with high force.
Splitter blade that operates with high force can cause a hazard of flying debris. Do
not let bystanders stand closer than the safety distance of 10 metres from the
machine. Stop the attachment if others get within the safety distance.
Risk of tipping over - Keep loads close to ground while driving. Carrying heavy
loads can shift the centre of gravity of the loader and lead to tipping over of the
loader. For the best stability always transport loads as low and close to th
e loader as
possible, with the telescopic boom completely retracted, to keep the centre of gravity
low.
Risk of crushing - Never go or allow anyone else to go under the loader boom
or attachment. The stability of the loader may change when leaving the driver’s seat,
leading to tipping over of the machine. Always remember that the boom may lower
unexpectedly due to loss of stability, mechanical fault, or if another person operates
the controls of the loader, leading to crushing hazard. The loader is not i
ntended to
be left to keep a load elevated for longer periods. Lower the attachment firmly on the
ground before leaving the driver's seat and never allow anyone to be under the boom
or attachment.
Make sure to use only an attachment that is in good condition. Check the attachment
thoroughly in regular intervals. Do not modify the attachment in a manner that would
affect its safety. It is prohibited to drill holes on the attachment, and welding or other
means of fixing hooks or other objects on the attachment is strictly prohibited.

WARNING
Keep the loader articulation in straight position when handling heavy loads. When
turning the articulation, the loader may tilt forward.
Make sure that the surface can bear the total load. Also follow the correct tyre
pressure settings.
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.
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 crushing -
Going under the loader boom or an
attachment can cause serious injury or death. Neve
r go
under the loader boom and prevent others from getting near
lifted boom or attachment. Going under a raised attachment
or loader boom is dangerous, as the boom may lower due to
loss of stability, mechanical fault or when other person
operates the contr
ols of the loader. Lower the attachment
firmly on the ground to a safe position before leaving the
driver’s seat.
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.

3.1 Safe shutdown procedure
Safe stopping of the attachment, before going near the attachment:
WARNING
Alway
s stop the attachment following safe stopping procedure before leaving
the driver's seat.
Safe stopping procedure prevents all unintentional movements of
the attachment. Note that the loader boom can move down even if the engine of the
loader is turned off. Safe stopping procedure:
Lower the boom and the attachment on the ground.
Shut down the loader engine and lock the parking brake.

Release residual pressure from the hydraulic system; move all hydraulic control
levers to their extreme positions a couple of times.
Prevent starting of the machine, remove ignition key.
3.2 Personal protective equipment
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 cycl
e. 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.
