This chipper, being coupled with a tractor three-point hitch, is designed for
disposal of wood waste, twigs, barks, branch-wood and other above-ground
biomass or for manufacture of chips from aforesaid materials and also for disposal
of redundant timber, such as sticks, deals, pickets etc. This chipper is designed for
material loading while the tractor is standing on flat and compact surface. In front
of the loading chute there should be an area with minimum free space of about 5
m.
The chipper can dispose all these materials with diameter up to 160 mm or flat
boards and plates with thickness up to 60 mm .
These wooden pieces must be free of metal, glass and other similar objects. While
working, the chipper must be relatively levelled.
The chipper should be controlled and operated by two attendants who in turns load
materials to be chipped in a loading chute.
Not Allowed Use
The chipper is not allowed to be used for disposal of aforesaid materials with
foreign matters and objects, such as metal, steel binding bands, glass cullet, stony
debris, ceramics etc.
It is not possible to use the chipper in the presence of unauthorised persons who
may stand or move in direction of discharge ducting. At work in residential zones
use the machine in accordance with regulations of the local authorities to avoid
disturbing of local inhabitants (noise level). While chipping, it is not allowed to
enter the area of ejected flying wooden chips.
On hilly terrain its loading chute height should not be lower than 600 mm.
It is not allowed to stand on higher spots around the machine while loading
materials into the chute.
Should some bar materials be loaded, then particular bars should be only up to 3 m
long.

Generally
- This machine is allowed to be operated only by attendants who are over 18 yrs
old, physically and mentally capable and demonstrably instructed with its
operation.
- One of two attendants at least (a tractor driver) should have a respective
driver's license, group "T".
- This machine can be operated by two persons only.
- Training courses for the operating staff should include also practical operation
under supervision of an experienced person or your dealer and with
explanation of necessary work safety instructions.
- Before working learn all functions of individual controls and safety elements
and carry out functional checks before any use. Check especially loading of
materials, functionality and height of the controller frame.
- By pushing the concerned controller in direction of material input the machine
should stop material loading immediately. Any repeated putting machine into
operation is possible only after bringing the frame in its initial position and
pushing the green button on the chute. The controller frame has to be
advanced in front of the hinged loading chute edge so that the attendant
stops the loading rolls at pushing the frame by hand (or leg or belly).
- It is strictly forbidden to change or to set the controller frame so that the STOP
position is hidden under the loading chute edge, see fig.
- To stop loading it is also possible to press the STOP button under the loading
chute.For deactivation turn the STOP button slightly and pull it up. Any other
repeated putting machine into operation is analogical, i.e. after bringing the
frame in its initial position and pushing the green button on the chute.

Chipper LS 160T
- It is forbidden to tighten the fixing nuts on the safety frame with intend to
increase its resistance against unwished switching off. Required force for
switching control should remain on values preset by the manufacturer, i.e. up
to 80 N in the lower horizontal frame part.
- Any removal of safety elements and guards from the machine and any further
operation without them are strictly forbidden.
- While chipping it is not allowed to enter the area of ejected flying wooden
chips. Every operator of this machine is fully responsible for any injury or
damage caused to the third persons within the operating reach of the machine.
- The end piece of the discharge duct (its upper turnable part) can be set only in
angles, see following figure. Never direct it toward the attendant's place!!
- While working the machine should fully rest on the ground with its frame
bottom part.
- Do not let the machine sink in ditches, trenches or similar undulations. It is
necessary to have flat surface around the machine while working and to keep
recommended loading heights.
- Keep this machine beyond children's and unauthorised person's reach. Avoid
their attendance while chipping.
- When using the chipper without any container or closed bin, keep anybody
beyond the area where chips are being thrown.
- When using the chipper with such a bin, never look inside if the chipper is still
working.

Chipper LS 160T
- At work in residential zones use the machine in accordance with regulations of
the local authorities to avoid disturbing of local inhabitants (noise, flying
chips).
- Warning !!! Be aware of ejected particles. They have substantial kinetic
energy. If the loaded wooden material contains not allowed parts, such as
metal, sand, glass etc., then such objects can reach a longer distance than
wooden chips. Direct the discharge duct to regulate its ejecting as needed.
- Instructions for use of the cardan shaft operation and the trailing tractor are an
integral part of this manual and should be always respected.
- The cardan shaft guard should be blocked against turning.
- While coupling the chipper to a tractor do not stand between its towing bar
and a tractor. Do not stand behind a towing tractor while backing. Ask other
person to help you with coupling.
- For coupling first attach the cardan shaft to the input shaft of the machine, to
the bottom draw rods and then the top draw rod of the tractor three-point
linkage. Finally attach the cardan shaft to the PTO shaft on the tractor.
While chipping the operator is obliged:
to use only such a chipper which is in optimal operating condition, not
damaged through transport, storage of from previous operation,
It is not allowed to put the machine into operation with its cardan shaft guard
damaged.
to check functions of all controls and safety elements, particularly the
controller frame, before putting the chipper into operation,
to avoid disturbing of other people with noise, exhaust fumes or ejected flying
particles (at windy weather),
to keep traffic rules and local regulations when going or working on or nearby
public roads,
If the discharge duct gets clogged, stop loading immediately. Clean the duct
at standstill only. For cleaning use only suitable hooks or sticks to release
pressed materials. After repeated putting the chipper into operation let the
machine run idle in the chipping mode for a while to empty the whole
discharge ducting and the chipping wheel space. If proper cleaning is required
then take always the switch key out of ignition before removing hoods and
block the tractor against unwilling motion.
While working, never lean over the loading chute and never push wooden
materials with your hand or foot only. While loading short materials, throw
11

them in the chute and push them forward between the loading rolls by means
of a wooden stick or a board, more than 160 cm long, to push materials
between the loading rolls.
Should the pressing stick be indrawn between the roles, do not try to pull it out
by hand - accident risk! Use always a new stick and go on working.
While working wear always personal protective equipment - protecting shield
or goggles, protective gloves, working shoes and working cloth properly
buttoned. Avoid wearing free parts, such as ties, scarves and shawls, belts etc.
