Use
The TP 250 wood chipper is designed for stationary wood chipping in the form of braches etc.
The machine must not be used for materials containing stone, metal or other foreign bodies. These
foreign bodies can in the best case dull the knives and in the worst case break the machine. Knives
and anvil can break when stone or metal comes in between them.
The machine must not be used for wood chipping of wood containing nails, screws, arming etc.
When feeding branches you must stand next to the feeding hopper (see fig. 1).
The branches can be thrown around when the retract rollers get a hold of them.
Logs must be fed into the machine from the back (see fig. 2).
Figure 1 Feeding branches
Figure 2 Feeding logs
Remember to keep the knives and anvil sharp, it makes feeding easier and gives a better quality
chips, and besides it lovers the use of fuel considerably.
The machine must be inspected daily, meaning the rotor housing must be opened and the rotor,
knives, anvil etc. must be inspected. By doing this you prevent unexpected stops and prolong the
life of the machine.
The tractor or trailer upon which the machine is mounted must always have the brakes activated
during work.
The machine must not:
·
·
Be used for other materials than wood
Be used to push trees, stubs etc.
There must not be equipment like forest chains, axes, chain saws etc. in the feeding hopper.

5.1 Before use
The machine is equipped with a lifting point which is to be used when lifting the machine with a
crane or any other hoisting device (ground assistance) (see Fig. 3). The machine can also be lifted
with a fork lift truck. This is done by using the holes made for this purpose on both sides of the foot
(see fig. 4). Make sure that the forks of the truck are put all the way through otherwise the
machine can tip over. The TP 250 MOBILE TURNTABLE is mainly transported on the trailer wheels,
but it can also be lifted with a fork lift truck under the trailer bearers (see fig 5).

Store the manuals for the PTO member with this manual in the manual box on the machine.
Before operation you must check that the wood chipper cleared of foreign bodies. The machine
must be uncoupled from the tractor’s PTO, and for the MOBILE models, the key must be removed
from the ignition before opening for the rotor. Check that the rotor is at a complete standstill. Turn
the ejector tube so that it faces the opposite direction of the rotor housing (see fig. 6). Loosen the
bolts that hold the upper and lower rotor housing together. Lift the top part of the rotor housing
up until the ejector tube rests on its own. Turn the rotor a few times by hand. Remove any foreign
bodies.
Figure 6
Position of ejector tube
when opening rotor
Check that the gap between the knives and the anvil is correct = 0,7 mm. The knives have a fixed
knife position = 13 mm. Check that the knives are not rubbing on the anvils.
Lift the top part of the rotor housing back in place and tighten the bolts.
Check that all bolts, nuts and screws are tightened properly.
Remember to lubricate all the lubrication points (see maintenance schedule, page 16).
Old hydraulics and motor oil and used oil filters and air filters must be handed in at an approved
receiving station.

5.2 Mounting instruction
The machine is designed to be mounted on the tractor’s three-point-suspension or trailer mounted
with its own engine.
Machines for mounting on the tractor’s three-point-suspension is delivered with a PTO axle with
either 1 3/8" - 6 splines or 1 3/8" - 21 splines.
At 1000 rpm, certain types of tractors a PTO axle with 1 3/8" - 21 splines must be used.
The PTO axle must be mounted with free running on the machine side.
Linddana uses Walterscheid 2400 with free running which comes with the machine.
The length of the PTO axle has to be adapted to the tractor following instructions from the supplier
of the PTO axle. See the attached manual for the PTO axle.
The machine must stand on a plane, horizontal surface during use and the tractor mounted
machines must be attached to the tractor’s three-point-suspension (see fig. 7). The tractor’s brakes
must be properly activated. Trailer mounted machines must also have their brakes activated (see
fig. 8).
When starting the machine: Engagement must be done with the motor running at idle speed or at
as few revolutions as possible in order to avoid overloading of the PTO axle, gear box, tractor and
wood chipper.

6.3 Noise level
The sound effect level and the sound pressure level from the TP 250 PTO have been measured
during use at 1000 rpm on the rotor disc, powered by a tractor.
The sound effect level and the sound pressure level from the TP 250 MOBILE have been measured
during use at 930 rpm on the rotor disc, powered by the Hatz 4L41C motor engine.
The measurements have been conducted according to test provisions
Directive 2000/14/EC, 3. July 2000
EN ISO 3744, 1995
ISO 11201, 1995
ISO 4871, 19. March 1997
EN 13525, 17. February 2005
The guaranteed sound effect level which will be given by the manufacturer according to directive
2000/14/EC are as follows:
TP 250 PTO: 127 dB (A) re.1pW.
TP 250 MOBILE: 127 dB (A) re.1pW.
The machine’s sound pressure level at the operator’s seat is measured according to ISO 11201 at:
TP 250 PTO: 110 dB (A)
TP 250 MOBILE: 109 dB (A)
The above mentioned values have the common uncertainty for the method of measuring and the
estimated variation in a product line for the type of machine. Detailed information on the
measurements and results as well as estimation of uncertainty are found in a thorough report
which can be given out on demand.
The sound level is of such a character that hearing protectors are prescribed during use of the
machine.
6.4 Environmental instructions
When changing hydraulic oil or engine oil, oil and used oil filters and air filters must be handed in at
an approved receiving station.
Oil spills must be avoided as much as possible. At oil spills, the spilled oil must be cleaned up and
handed in at an approved receiving station.
Worn out parts must be disposed of for recycling.
When the machine is worn out it must be disposed of properly. Hydraulic oil and engine oil must be

Operation of the machine
The wood chipper is equipped with two hydraulic rollers, a pressure compensated flow valve, a
control valve, an operation bow with a reset handle and a funnel handle (see fig. 10).
The funnal is hinged.
To make it easier to open and close the folding infeed funnel used the funnel handle
that pulled out. Funnel handle is pushed back after opening and closing of the funnel.
The operation bow must be in the stop position (0) during start (see fig. 11). After start you release
the reset handle and pull the operation bow into the middle position (A) and the rollers will turn.
The material is now pulled into the machine.
By pulling the operation bow towards you (B), the flow of oil in the control valve is turned and the
rollers reverse, the material is now pushed out of the machine.
When the machine is either stopped (0) or reversed (B), the reset handle will automatically block
the operation bow. It is now necessary to release the reset handle before the operation bow can
be moved into the middle position (A) and the rollers can pull the material into the machine.
This reset handle is a safety measure so you cannot start the rollers by accident so they pull
material into the machine.

By turning the adjusting screw on the flow valve you can find the correct rpm. Never go to fast with
the rollers because the wood will work like a brake if the pressure on the rotor is too big with the
ensuing increase in use of fuel. Branches can get wrapped around the rollers if the rpm is too high.
In the table below (table 1) are stated the recommended rpm on the retract rollers at a desired
chip length. The speeds vary with the number of revolutions on the PTO axle. The chip length can
be regulated on the flow-regulation valve on the wood chipper for smaller chip lengths than
indicated in the table.

8.2 Lubrication and oil
The Wood Chipper is as standard, factory-filled with hydraulic oil of the type Hydraway HVXA 46.
When replacing the oil, use the same type of oil or oil with equivalent specifications. Do not mix
together different types/brands of oils.
As an accessory, the Wood Chipper can be delivered factory-filled with biodegradable oil of the
type saturated ester, Hydraway SE 46HP. When replacing the oil, use the same type of oil or oil
with equivalent specifications. Do not mix together different types/brands of oils.
Old hydraulic oil and engine oil as well as used oil filters and air filters should be handed in to the
local receiving station.
Lubrication nipples are lubricated according to the maintenance schedule with Statoil Uniway Li62
or a similar product.
The machine is equipped with a hydraulic oil tank which is integrated in the rotor housing. The tank
is equipped with a filler neck, an air release valve, a level glass and a return filter.
When changing the hydraulic oil, the filler neck is opened (see fig. 12).
The drain plug is unscrewed. The oil is drained into a canister for proper removal. When the tank is
almost empty, the tank is sucked empty with an oil suction device. The drain plug is screwed back
and new hydraulic oil is slowly filled in (25 litres for TP 250).
Oil is filled in until the level glass is half filled.

8.3 Maintenance of the retract rollers
The retract rollers pull the material into the rotor disc and the knives.
The plates on the bottom retract roller must be kept sharp in order to keep the retract force.
This is how it is done:
Stop the machine and the drive. Uncouple the tractor’s PTO. Check that the rotor is at a complete
standstill. Turn the ejector tube so it faces the opposite direction of the rotor housing (fig. 6).
Loosen the bolts which hold the two parts of the rotor housing together and open the rotor
housing. With multigrip pliers or something similar, the spring is lifted off the top retract roller.
Grab the handle and open the roller housing and push the locking pawl into the lock in the side
plate (fig. 13). The roller housing is now secured from falling down.
Now the flats on the bottom retract roller can be grounded with an angle grinder.
Turn the rotor carefully with the operation bow in position forward or reverse. By doing this, the
retract roller is turned so all the plates can be ground.
Remember that the welding seams are not to be ground away.
Locking pawl
Figure 13 Securing with locking pawl
When the roller has been grounded, the top retract roller is lowered back in place. The spring is put
back with multigrip pliers. Close the rotor housing and screw the bolts back.

8.4 Changing worn parts
8.4.1 Anvil
The anvil in the machine is used as wearing bar for the knife in order to cut the wood. The anvil
must be sharp-edged otherwise the wood will bend down and the cut will become frayed. The
machine is equipped with one horizontal anvil with two edges and two vertical anvil. The horizontal
anvil can be turned.
This is how it is done:
Stop the machine and the drive. Uncouple the tractor’s PTO. Check that the rotor is at a complete
standstill. Turn the ejector tube so it faces the opposite direction of the rotor housing (fig. 6).
Loosen the bolts which hold the two parts of the rotor housing together and open the rotor
housing. With multigrip pliers the spring is lifted off the top retract roller and the roller housing is
lifted and secured with the locking pawl (see fig. 13).
Dismantle the three bolts which hold the horizontal anvil. This is done from the outside and from
below. The anvil is taken out and turned/replaced. Before the anvil is put back, the anvil and the
bearing surface must be cleaned carefully. The distance between the knife’s edge and the anvil
must be 0,5-0,9 mm. (See fig. 14). The tightening factor for the bolts for the horizontal anvil is 200
Nm / 20 KPm. (Accessory: in the tool kit there is a torque wrench).

The vertical anvil is unscrewed and removed from the inside. Before a new one is put in, the anvil
and the bearing surface must be cleaned carefully. The anvil is set to a distance of 0,5-0,9 mm to
the knives. Use a new precision feeler gauge. The bolts for the vertical anvil are tightened to 50 Nm
/
5 KPm.
When the anvils have been turned or replaced and all the bolts are tightened, the roller housing is
lowered with the top retract roller in place. The spring is put back by using multigrip pliers (see fig.
13).
Turn the rotor a few times to make sure that there are not any objects in the rotor housing. Close
the
rotor housing and tighten the bolts (see fig. 15).

Figure 15 Tighten of bolts in the rotor housing
8.4.2 Knives
The machine is equipped with three knives.
The knives must always be changed in sets. The knives belong together in sets, also when they are
ground so that they are always of equal width. If the knives are not of equal with the rotor will be
out of balance which will lead to unnecessary strain on the bearings and vibrations in the whole
machine.

This is how it is done:
Stop the machine and the drive. Uncouple the tractor’s PTO. Check that the rotor is at a complete
standstill by looking at the two-coloured axle end. Turn the ejector tube so it faces away from the
rotor housing (fig. 6) Loosen the bolts which hold the two parts of the rotor housing together and
open the rotor housing.
The rotor is turned until the rotor lock can go into one of the holes on the rotor. Now the rotor is
locked (see fig. 16). Be careful that your fingers are not near the knives when the rotor is turned.
Rotor lock
Figure 16 Locking the rotor with rotor lock
Remove the four nuts which hold the knife to the rotor. Take out the knife. The bearing surfaces on
the chipping disc and the knife must be cleaned properly before fitting the knives. On fitting the
nuts must be slightly greased (m=0,125) meaning thin oil, WD 40 or something similar. Copper
grease, MoS2 or similar low friction grease must not be used.
Check that the distance between the knife’s edge and the anvil is set correctly at 0,7 mm.
The nuts must be tightened with 95 Nm / 9,5 KPm. (Use a torque wrench for this which is included
in the tool kit. This can be bought as an accessory).
When the knives are changed, the rotor is turned a few times to make sure that there are not any
objects in the rotor housing. Close the rotor housing and tighten the bolts (see fig. 15).

8.4.3 Scrapers and facing plate
The machine is equipped with three square scrapers on the rotor disc, a triangle scraper in the
rotor housing and a facing plate in the ejector tube (see fig. 17).
Scraper
Facing plate
Figure 17 Placement of the scrapers and the facing plate
The purpose of the scrapers is to remove any material which might get stuck to the knives.
At the same time the square scraper on the rotor removes material which falls off in front on the
chipping disc.
This reduces the wear to the casing and reduces the consumption of fuel.
The square scrapers can be turned once before being changed, while the triangle scraper and the
facing plate should always be changed when they are worn.
This is how it is done:
The rotor is turned until the rotor lock can go into one of the holes on the rotor. Now the rotor is
locked (see fig. 16). Be careful that your fingers are not near the knives when the rotor is turned.
Dismantle the countersunk bolts which hold the square scraper on the rotor. Turn the square so
that a sharp edge points up. Clean the block and the bearing surface. Put the square scraper back.
If it is worn on two edges, the square scraper has to be changed. Always change the square scraper
on the rotor in sets. Change the triangle scraper when it is worn.
The facing plate is mounted in the top part of the rotor housing and can easily be changed by
dismantling three bolts on the outside of the rotor housing. If chip quality is not important the
facing plate in the ejector tube can be removed. This will increase the capacity of the machine and
save fuel. The facing plate has to be dismantled when chipping wet conifer with a lot of needles.
Then a good ejection is ensured.
When the scrapers have been turned or changed, the rotor is turned a few times to make sure that
there are not any objects in the rotor housing. Close the rotor housing and tighten the bolts (see
fig. 15).

8.4.4 Casing
The TP 250 is equipped with an interchangeable casing at the bottom of the rotor housing. The
casing absorbs the wear and tear which would normally happen at the bottom of the rotor
housing.
This is how it is done:
Stop the machine and the drive. Uncouple the tractor’s PTO. Check that the rotor is at a complete
standstill. Turn the ejector tube so it is pointing away from the rotor housing (see fig. 6) Loosen the
bolts which hold the two parts of the rotor housing together and open the rotor housing. Remove
the top part of the rotor housing.
Dismantle the six bolts and nuts which hold the casing to the bottom part of the rotor housing (see
fig. 18).
Hit with a hammer on the part of the casing which sticks up over the edge of the rotor housing at
the hinge side to loosen the casing. Now the casing can be swung out.
Casing
Figure 18 Changing the casing
Before a new casing is put in, you must clean the bottom of the wood chipper. Mount the new
casing with six bolts. Put the top part of the rotor housing back.
When the casing has been changed the rotor is turned a few times to make sure that there are not
any objects in the rotor housing. Close the rotor housing and tighten the bolts (see fig. 15).

8.4.5 Adjusting the V-belts
Pump transmission
The retract rollers are run hydraulically. The hydraulic pump to the retract rollers is run by V-belts.
The V-belts need to be check regularly or when the belts are suspected to be slack.
This is how it is done:
Stop the machine and the drive. Uncouple the tractor’s PTO. Check that the rotor is at a complete
standstill. Turn the ejector tube so it faces away from the rotor housing (fig. 6) Loosen the bolts
which hold the two parts of the rotor housing together and open the rotor housing.
Loosen the four screws which hold the hydraulic pump in place and adjust the tension by turning
the adjusting screw. Used belts are allowed to bend 5.87 mm when they are pushed down with 5054 N (5-5,4 kg), for new belts this number is 57-61 N (5,7-6,1 kg) (See fig. 19). The belts can be
measured with a gauge for this purpose which can be bought as an accessory.
Measure point for
tension
Figure 19 Adjusting the tension
When the V-belts have been tightened, the rotor is turned a few times to make sure that there are
no objects in the rotor housing. Now the rotor housing has to be closed and the bolts have to be
tightened (see fig. 15).

8.5 Grinding of knives
It is very important for the quality of chips that the knives are sharp. They have to be checked at
least once a day. The grinding interval of the knives can be prolonged by grinding them with a
carborundum stone regularly.
The grinding can be done as wet grinding with a bond stone (see fig. 20). Never use an angle
grinder or a similar tool for grinding the knives.
Figure 20 Wet grinder
When grinding knives you have to pay attention to the width of the knife set. The width has to be
the same because of the balancing of the rotor. Therefore, the knives always have to be ground in
sets. The knives must have a measurement of min. 90 mm (See fig. 21). After that they must be
thrown away.
The edge of the knives must be ground at an angle of 28°. (See fig. 21).

Engagement of the wood chipper.
At cold starts: Start the engine. Set the throttle so the engine runs smoothly at low revolutions. Let
the engine run 30-60 seconds depending on the temperature. Then the wood chipper is engaged
slowly and the rpm are increased to working speed “full throttle”.
At warm starts: Same approach is followed. Only it is not necessary to let the engine heat up
before engaging.
The wood chipper must not be engaged at full throttle.
When stopping: Let the wood chipper run out of material. Disengage the wood chipper. Let the
engine run idle for approximately 30 seconds before the throttle is turned to stop.
Turn the ignition key to neutral. (See symbols on the starter box).
