- 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.

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

approximately levelled and the cardan shaft is squeezed utmost.
- Measure the distance between safety splines on both shafts.
- Press both ends of the cardan shaft together by hand as much as possible and
measure the distance between both safety pins on the cardan shaft.
- The distance measured on the cardan shaft should be shorter at least by
20 mm than that between two safety splines on both shafts (input and
PTO shaft). Should this length be longer, the cardan shaft should be
shortened accordingly, see instructions of the cardan shaft manufacturer.
It is not allowed to use such a cardan shaft, if its length
(distance between two safety pins), is longer than that
measured between safety splines on the input and PTO shafts.
Otherwise it may bring damage on the shaft or even on the
28
Chipper LS 160T
tractor.
- Pay special attention to maximum retraction of the cardan shaft. Lift up the
machine in its top position. The overlap as measured inside the shaft must be
sufficient. For more details, see instructions of the cardan shaft manufacturer.
- Try to swing out the machine to the left or to the right – max. permissible
angle of the cardan shaft crank should not be exceeded. Otherwise it may bring
damage on the shaft. For more details, see instructions of the cardan shaft
manufacturer.
- We recommend to use a cardan shaft completed with a freewheel clutch.
- Use always such a cardan shaft that provides transmission of power 20 – 50
kW according to the tractor type and max. rated speed permissible for the
machine.
Putting into Operation
Before start check if the loading chute and the discharge duct are free of
any materials. Direct the discharge duct out of possible motion of other
persons or prevent other persons to enter the working area. At work
proceed always very carefully.
- Let the three-point hitch go down on the ground.
- Swing away the hinged part of the loading chute and lock it.
- Avoid directing the discharge duct to the area of possible motion of other
persons. Lock the duct end piece in its working position.
- Set the safety frame in the initial position for loading.
- Close all guards (if opened).
- Turn the PTO shaft on and let it running at slightly increased speed, as rated
for 540 rpm shaft speeds.
As soon as the PTO shaft starts turning, the chipping wheel and V-belts
are set in motion. Keep off such places and space of the loading rolls
while in motion.
- Turn the switch key in the START position and then release the key in the
position RUN. In this way the NOSTRESS unit is activated.
29
Chipper LS 160T
- Press the green button for loading. CAUTION!! The loading rolls start turning
immediately.
- Having turned the chipping device on wait for speed stabilization. With that
you may soever increase or reduce the tractor PTO shaft speed.
- CAUTION!!! As soon as the PTO shaft starts turning, the hydraulically
powered elements can be set in motion as the hydraulic system of the
machine is already pressurized.
- CAUTION !!! As soon as the PTO shaft is ON then chips from previous
operation may be ejected from the discharge duct.
- Carry out functional checks of the safety frame for loading. Push the frame in
the in-feed position and the loading rolls start turning (loading). By next short
pushing the frame the rolls should stop turning immediately – EMERGENCY
STOP position.
Legend:
A - loading chute, B - safety frame, C - attendant's place, D - loading chute edge,
E - infeed direction, G – buttons for control of loading and reversing
- The safety frame must be always adjusted so that the
EMERGENCY STOP must be activated before the point D – loading
chute edge.
- Do not leave the machine unattended.
30
Chipper LS 160T
Chipping
- The chipper is powered by a tractor combustion engine. Do not
start it in confined or ill-ventilated spaces or under conditions of low
visibility.
- While chipping the chipper must always be properly coupled to a
tractor.
- It is not allowed to use the cardan shaft with its damaged guard. This guard
must be properly locked against turning. Check up locks on the sliding shaft.
- Set the discharge duct in required direction. The discharge duct cannot be
directed to the attendant's place, see following figure.
- When loading materials and during operation of the chipper the attendant
should always stand in the attendant's place, see fig.
- Having turned the chipping device on wait for speed stabilization. With that
you may soever increase or reduce the tractor PTO shaft speed. For correct
chipping functions it is necessary if the tractor PTO shaft speed is 540
rpm(1000 rpm).
- Wooden chips can be gathered in bulk or into a container located on a towing
vehicle.
- While discharging into a container, pay your attention to ejecting to avoid
ejecting chips back out off the container.
- Before displacement of the chipper to another workplace, first turn the PTO
shaft off and wait for run-out of all rotary parts. Afterwards, lift up the
machine in the top (transport) position. Never pull the machine while resting
on the ground!
31
Chipper LS 160T
- Do not load materials with parts of metal, glass, ceramics and other similar
objects.
- Do not chip or load materials while driving.
- Having put materials in the loading chute/between loading rolls, release the
loaded material immediately and keep a certain distance from the chute.
- Do not load materials with diameters exceeding 160 mm and 3 m in length. Do
not load wooden boards with thickness more than 60 mm.
- When working, never lean over the loading chute and never pull out wooden
materials, already loaded, from the chute.
- Do not load materials with diameters exceeding 160 mm. Speed of loading
should correspond with quantity and characteristics of the material to be
loaded.
- If loaded materials are spreading with risks of catch holding of attendant's
dress being drawn in the loading chute then it is necessary to prepare such
materials accordingly (trimming, cutting).
- Pay special attention to thorny materials, such as acacia and roses, which may
easily catch your sleeves.
- Be careful while loading since materials may unexpectedly move in unwished
directions.
- In case of two attendants it is necessary to make simple signals clear before
working. During operation it is not easy to make any agreements because of
operating noise.
- Observe the working area. If any person, children or animals approach while
chipping, then stop working immediately.
- Be aware that there is a certain time period required between loading, chipping
and final ejection of chips.
- As far as possible load the chipper evenly, adapt loading speed accordingly
and keep continuous chipping.
- While loading, stand aside the loading chute.
- While loading short materials, throw 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.
- Never use metal objects. They could cause serious damage of the loading rolls
and blades.
- When finishing the work, first wait for emptying of the loading chute.
32
Chipper LS 160T
Recommendations:
Do chipping at rated PTO shaft speed only, i.e. at
sufficient power of the chipping wheel for ejecting chips.
Being loaded short and fine materials may deposit or clog
the space behind the loading rolls in front of the chipping
wheel. To avoid such problems and clogging put
occasionally also some longer branches.
To prolong service life of blades never put any materials
with parts of impurities, such as of metal, glass, ceramics
and other similar objects.
Optimal sharp blades reduce operating costs of the
loading and chipping equipment (reduced wear of the
chipping device).
If loaded material is free of any impurities then a grinding
interval for blades may last several months or several
hundreds m3 of loaded materials.
Blunt blades are evident on chipped edges which are not
clean but broken.
The chipper is optionally equipped with its speed regulation and the NOSTRESS
system intended particularly for tractors with power less than 30 HP.
This regulator reduces material feeding upon contingent overloading (PTO shaft
speed dropping).
The chipping wheel speed is set by the manufacturer to 900 (1100) rpm to turn the
rolls off and to 910 (1110) rpm to turn the rolls on again.
Recommendations!!
Should the loading rolls be frequently turned off while chipping,
it means that there is too much material loaded and the chipping
device is overloaded. To avoid this overloading:
reduce volume of material to be loaded, or
reduce infeed speed of the loading rolls
33
Chipper LS 160T
The loading rolls infeed speed can be reduced by the regulating screw (see arrow
on following figure) under the hinged part of the loading chute. To change the
infeed speed, just turn the regulating screw accordingly.
Putting out of Operation
If you want to stop chipping:
- In case of loaded material wait for emptying of the loading chute.
- Wait for emptying of the discharge duct.
- Turn the tractor PTO shaft off.
Warning! The cardan shaft is equipped with a freewheel clutch. When
turned off, the rotor of the chipping device runs out – approximately 120
sec.
- Regardless of this running out, turn the switch key in the STOP position.
Emergency Situations
Put the chipper out of operation immediately in
following cases:
- If any person or animal approaches under 20 m while chipping, then stop
working immediately.
- If any breakage, damage or disengagement occurs, stop chipping immediately.
- If you heard any strange noise or vibrations or felt a strange smell while
chipping, then turn off the machine immediately and contact your dealer or
directly the manufacturer.
34
Chipper LS 160T
- In case of fire or breakdown, stop chipping immediately.
- In case of fire use foam extinguishers only.
- If you cannot damp the fire down yourself, call for a fire brigade.
- If an attending person gets caught by rotating parts or loaded materials, stop
the loading rolls by pushing the safety frame (STOP position). Stop working
and go on only if the attending person is uninjured and fully concentrated.
- If the discharge duct gets clogged, stop loading immediately and reverse the
loading rolls by pushing the safety frame (position REVERS). Turn the PTO
shaft off and having all rotary parts stopped (after about 1-2 min) use an
elastic rod and try to release the clogged material in the end piece of the
discharge duct. Having released clogging materials, try to turn on the chipper
again. If it is not possible yet, hinge away the upper hood part and try to
remove all materials by hand (the PTO shaft must be OFF). Be aware, the
chipping wheel must be blocked properly.
- To release the discharge duct clogged, do it always at standstill only.
Technical Description
This machine consists of following main parts:
- chipping device
- loading chute
- loading rolls
- chipping wheel
- discharge duct
- frame
Chipping Device
Loading chute
The loading chute is made of welded steel plates consisting of two parts: fixed
and hinged one. The hinged part serves as an extension of the chute with a safety
frame and is protected by a terminal switch. This frame, if pushed by an attending
person or branchy materials being caught, turns the loading rolls off. The chute
itself, shaped as a square pyramid, is decreased in width toward the loading rolls
and in this way loaded materials are pressed together.
35
Chipper LS 160T
Loading rolls
These rolls take over loaded materials and move them to the chipping wheel. Their
speed can be regulated according to the given sort of material and expected results
– chips.
Both rolls are ribbed and enable loading of materials and also pulling them out at
reverse turning if necessary (chipping wheel overloaded). Both rolls are powered
by a hydraulic motor.
If required, both rolls are outwards movable in order to adapt working to the
material to be loaded.
This machine is equipped also with loading speed regulation with sensing actual
speed of the chipping wheel. Assessment of actual speed and following speed
regulation are controlled by the NOSTRESS unit.
Chipping wheel
It is a steel disc serving also as a flywheel for absorption of shocks while chipping.
This wheel is put in ball bearings; a drive pulley is fitted on its shaft. The wheel is
equipped with two blades for cutting of loaded materials. Vanes welded on its rear
side serve for ejecting chips in the discharge duct.
The chipping wheel is installed in a rigid frame and protected by a steel plate. Its
protective shield consists of two parts and particular parts are bolted together. By
safety reasons the upper part is protected with a terminal switch for turning the
drive off if the shield was opened or got loose.
Discharge duct
This duct continuously extends the chipping wheel shielding and serves for
directing the ejected chips. The duct is turnable and its end piece (tilting gate)
serves also for setting the range of ejected chips.
Frame
This machine is attached to a rigid frame welded from hollow-space profiles. In the
front part there is a three-point hitch welded and intended for coupling to a tractor.
In the bottom frame part there are a belt gear and the machine input shaft.

- Check up the machine for completeness and its general condition.
- Any maintenance and servicing on the machine can be done at standstill only,
i.e. the PTO shaft off, the switch key being pulled out from the ignition box,
tractor wheels blocked against unwished motion.
- While servicing the chipper should be lowered on the ground.
- Pay special attention to all safety elements.
- Check up V-belts for tightness and wear.
- Keep regular intervals for lubrication of bearings.
- Check up condition of blades and chipping wheel vanes regularly.
- Check up hydraulic hoses for wear. Replace them if necessary or every five
years.

Blade Grinding
Blades, fitted on the chipping wheel, are double-sided, i.e. reversible if one side is
blunt.
Blades edge regrinding requires high demands for keeping cutting edge shape.
While grinding it is necessary to keep its optimal geometry, see following figure.
Proper shapes prolong blade service life.
While regrinding it is necessary to keep the same weight of particular
blades because of balance of their rotating mass. For grinding use
always a grinder with its magnetic table and a special jig.
Detailed geometry of blade edge
39
Chipper LS 160T
Grind every blade only up to minimum distance from edge to its fixing
bolt. i.e. 37,5 mm. This distance on a new blade is 100 mm, see
following figure.
Max. wear/grinding of cutting edge
Chipping Adjustment
Optimal operation of the chipping device requires proper setting of a clearance
between the blade and the opposite cutting edge. This distance should be set (see
following figure) and checked after fitting ground blades, then it grows with their
wear and chipped branches may be squeezed between the blade and the opposite
edge. It brings deterioration in quality of chipping.
Pay attention also to blades exchange. In such case set the given clearance bigger
to avoid damage of a new blade and its opposite cutting edge.
40
Chipper LS 160T
Recommendation: Check out conditions of blades every 40 operating hours.
Regrind blade edges if they are found blunt
Jointing elements (bolts and nuts) should be replaced together with The
blades exchange. Safety nuts should be used only once, since they lose
their self-locking properties if used repeatedly. The fixing bolts should
be tightened with torque of 100 Nm
NOSTRESS System – Speed Regulation
This system is intended for overload
protection of the combustion engine
consisting of an electronic control unit and a
speed sensor installed on the rotor shaft.
Control unit:
This control unit displays actual rotor speed
values. When the rotor stops, the unit
displays a total number of running hours
"TH" or a daily number of running hours
“DH”. To reset the current daily number, just
press both arrow buttons together, set up
the access code to “3003” and enter the main user menu. Select the submenu
“delete daily hours” and confirm the function “delete”.
Right function of NOSTRESS system:
The speed regulator reduces material feeding upon contingent overloading. For
example, the chipping wheel speed is set to 900 (1100) rpm to turn the loading
rolls off at speed loss and to 910 (1110) rpm to turn the rolls on again. Actual rotor
speed values are displayed on the control unit. However, actual engine speed
values are not displayed.
This control unit enables to set the speed according to the material to be loaded:
F1 – light branch-wood, shrubbery, twigs, hedges
41
Chipper LS 160T
Location of sensor under hood
F2 – medium hard wood, branch and leaf wood
F3 – hard wood, needle-leaved trees, bough, timber
Speed sensor:
This encapsulated sensor in fitted on a holder keeping its distance of 3,2mm from
the cam lobe. In the rear part of the sensor sleeve there is an orange LED installed
flashing in case of proper sensing.
Set-up of the speed sensor distance should be done at
machine standstill only
42
Chipper LS 160T
NOSTRESS system protection against overvoltage
Overvoltage occurrence in the electric installation blows the fuse and breaks the
TVS diode (Transient Voltage Suppressor / Transil) used to protect
sensitive NOSTRESS electronics against voltage spikes. Should the fuse (7,5 A) be
blown again, first replace the damaged TVS diode and then put a new fuse.
43
Chipper LS 160T
V-belt Tension
It is necessary to pay special attention to the routine maintenance and proper belt
tension adjustment because the V-belts on this machine transfer the engine torque
to the chipping wheel and the hydraulic pump.
For belt tension adjustment remove two side belt guards fixed here by fixing bolts.
Under these guards there is a belt gear for power transmission to the chipping
wheel and the hydraulic pump.
While tightening the belts proceed as
follows:
- Check up tension of new belts after
first 5 service hours and
afterwards always in intervals of
25 hours. Excessive slipping or
excessive tension will wear out the
belts prematurely and reduce their
life essentially.
- Adjustment of particular belts on the
hydraulic pump and on the chipping
wheel can be done independently.
- In case of three V-belts for the
chipping wheel it is necessary to
shift the belt pulley on the input
shaft.
- For adjustment of the belts for the hydraulic pump it is necessary to shift the
pump body.

- Loosen four nuts on the stretching bolts in the direction intended for pulley
shifting. For tightening loosen the nuts over the supporting plate and also the
nuts directly on the plate uniformly by 0,5 – 1 turn to let the belt pulley slide.
Having reached the recommended belt slack value, retighten all the bolts by
means of their lock nuts.
45
Chipper LS 160T
Hydraulic pump drive
Loosen four nuts of the fixing bolts holding the pump on the frame
uniformly approximately by 0,5 turn to let the pump slide in the intended
direction by means of the stretching bolt. Having reached the recommended
belt slack value, retighten the fixing bolts on the frame and the lock nut on the
stretching bolt. To make all the bolts accessible first it is necessary to remove
the belt guards over the belt pulley of the chipping wheel shaft.
Having finished the belt tension adjustment, replace the belts
guards.
Hydraulic oil filter change
The oil filter is installed in the hydraulic circuit and accessible left under the
loading chute.
We recommend changing the oil filter element always together with the hydraulic
oil change. This oil filter element is in fact a replaceable cartridge fixed on the
central bolt of the filter body. For its exchange it is necessary first to loosen it by
means of a special wrench.
Before filling new oil first screw up a new filter element.
Fill the hydraulic oil tank up to 17 litres only (up to the MAX mark on the oil
tank).
It is strictly forbidden to put this chipper into operation without
any oil filter or with its filter element clogged or damaged.
Replace the filter element only at stillstand of the machine.
Hydraulic oil temperature should be lower than 45oC.
46
Chipper LS 160T
Electric
Installation
Protect all wires against contact with oil products. Keep all
elements clean and avoid any damage of wires - short circuit
risk. All connections must have clean and proper contact
surfaces to avoid intermediate resistance at a wrong contact
point.
Hydraulic Oil
Change
Do the first oil change after the first 500 running hours or after
the first season. Next oil changes always after 1000 running
hours. It is recommended changing the filter element together
with the oil change.
