2. Designed purpose of use
The AVANT Log cutter/splitter 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 by one person at a time for cutting and splitting
firewood. The log cutter/splitter can be used either attached to the loader, or with an optional hose extension
kit, it can be used further away from the loader. The Log cutter/splitter must be placed firmly on the ground.
The Log cutter/splitter is equipped with a hydraulic infeed belt and discharge conveyor as standard. The log
lifter option must not be used with 400 series loaders.
The Log cutter/splitter cuts the log with a chain saw blade to the adjusted length between 200 and 500 mm.
The splitting activates automatically after cutting. The attachment splits wood with a hydraulic cylinder, which
presses the wood against a splitting wedge. The diameter of the log can be up to 310 mm. The hydraulic
cylinder returns to set position after the wood has been split. A 4 way splitting wedge is standard equipment; 6
way wedge is available as an option. The splitting wedge is adjustable, making it possible to split the wood
into only 2 pieces, when needed.
The Log cutter/splitter 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 Log cutter/splitter is intended strictly for one
operator only. Others must not get near the attachment or the loader. The Log cutter/splitter is intended for
outdoor use only.
Always read the original manual of the Japa 315 and this Avant operator's manual. This operator's manual
includes additional information that is important when using the Japa 315 firewood processor with the Avant
loaders.
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. Fa
miliarise 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.
WARNING
Risk of serious injuries - Read all manuals.
This annex for
the original User Manual of the log cutter-
splitter does not
include all necessary information about safe and correct use
of the equipment. Ensure that you have received and read
also the origina
l User Manual, which is delivered with the
machine. Contact your Avant or Japa dealer, if the original
User Manual is not available.
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 and cutting - The Log cutter/splitter must be used by only one
operator at a time.
Always keep in mind that the cutting blade, strong cylinder, or
sharp splitter blade can cause serious injuries if not handled properly. The operation
of the Log cutter/splitter creates
a risk of crushing and cutting; do not let others near
the attachment when it is in use. Keep a safety distance of minimum of 2 meters.
Risk of getting run over by moving machinery - Never operate the Log
cutter/splitter if anyone is seated on the driver's seat of the loader.
The operator
must be the only person working with or staying close to the attachment and the
loader.
Risk of crushing - Do not walk under the conveyor. Keep a safety distance of
minimum of 2 meters.
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 the loader as
possible, with the telescopic
boom completely retracted, to keep the centre of gravity
low.

WARNING
Risk of crushing - Never go or allow anyone else to go under the load, the
loader boom or the attachment.
The stability of the loader may change when
leaving the driver’s seat, leading to ti
pping 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 intended 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.
When using the Log cutter/splitter, keep it securely against the ground. When
oper
ating the log cutter/splitter uncoupled from the loader with the hose extension kit,
pay spceial attention to ensure that the attachment stays firmly in upright position.
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.
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 equipment 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.
