GENERAL DESCRIPTION AND INTENDED USE OF
THE CHIPPER
FARMI 260 is a disk chipper for tractor-mounted ope-
ration. As the chip size is adjustable, the chipper can
be used e.g. for the production of chips to be used
for landscaping or for bio energy. The chipper can be
used to chop trunks, twigs and tree tops as well as
chopping waste and saw mill waste. The chipper can
shred wood with a max. trunk diameter of 260 mm.
The FARMI 260 chipper is mounted to the 3-point hitch
of a tractor. It is driven by the tractor PTO. The driving
force is transferred to the chipper via the PTO drive
shaft. During chipping, the chipper rotor on which the
blades for cutting the material are mounted is driven
by the tractor. From the knives, the chips are fed to the
additional knives which cut the chips to the desired
size. Finally, the chips are discharged to the desired
position using a discharge pipe. Depending on the
feed unit used, the material to be cut is loaded into
the chipper manually or using a grab loader.
The FARMI 260 chipper must always be used together
with one of the following Farmi feed units:

• Attach the drawbar to the outermost holes of the
chipper in order to use as long a PTO shaft as pos-
sible; this increases the shaft’s service life.
• Mount the chipper on the tractor’s 3-point hitch. If
the tractor cannot lift the chipper up, or if the front
of the tractor becomes too light, move the draw-
bar to the inner holes.
• Tighten the nuts (M20) to 340 Nm.
MOUNTING OF THE FEED UNIT
• For hydraulic feed units, a tting block is supplied
which is to be installed between the chipper and
the feed unit. Please make sure to install the ap-
propriate tting block. The tting block for the
feed unit HF231-HM has a height of approx. 180
mm, see g. 6a. The tting bock for the feed units
HF260-EM, HF260-EL and HFC260 has a height of
approx. 135 mm. See g. 6b.
• The tting block is installed on the pins in the bot-
tom section of the feed opening. See gs. 6a and 6b.
• Carefully install the tting block. Make sure the tip
of the tting block is seating tightly on the feed
opening. Make sure the working surface is clean.
Every time a knife is changed or at least every 100
operating hours, check the system for vibration
fatigue failure.
• The instructions for mounting the feed unit are to

SHORTENING THE PTO SHAFT
The use of too long a PTO shaft
with a 3-point hitch could damage
the chipper’s bearings or the
tractor’s PTO shaft. Both halves
of the PTO shaft must be shorte-
ned equally.
Recommended PTO shafts:
• Bondioli & Pavesi A6 + (RA1 with overrunning
clutch.)
• Walterscheid W2400 + (F3 with overrunning
clutch.)
If the tractor features a PTO brake, an overrunning
clutch must be used.
1. Mount the machine on the tractor’s 3-point hitch.
2. Lift the machine with the hitch so that the distance
between the splined shafts is at its shortest. Fig. 8.
3. First, cut the thicker shield to the correct length (1).
Remember the 20-40 mm clearance. Then, cut a si-
milar length from the prole tube (2). Shorten the
other PTO shaft half similarly. Remove burrs using
a le.
4. Insert the inner tube in the outer tube and carefully
move the machine up and down. Ensure that the
shaft was shortened suciently. Check that the
shaft has a 20-40 mm clearance. In addition, move
the machine sideways and ensure that the PTO
shaft does not bottom.

The warranty does not cover defects resulting from:
• misuse of the product
• inadequate maintenance
• modications of the product made without
the manufacture’s consent
INSTALLING THE SCREEN AND BREAKER
The chipper can be equipped with a twig breaker or a
high-power breaker or optionally with a screen. How-
ever, the screen cannot be mounted in conjunction
with the breakers.
The breakers are intended to break the chips into
smaller pieces before they enter the discharge pipe.
The FARMI 260 chipper can also be used to shred hard
plastics. For this purpose, the twig or high-power
breaker must be replaced by a screen. The screen pre-
vents excessively large plastic chips from entering the
discharge pipe.The screen may only be used for scree-
ning thin plastic pieces. The screen must be removed
before chipping other materials!
The breakers or the screen are attached inside the up-
per chamber. The set screws (1) of the lower section
are inserted using Nord Lock lock washers (2) and are
secured with M16 lock nuts. Tighten the nuts with 170
Nm. The locking screw (4) of the upper section is in-
serted using a Nord Lock lock washer and is secured
with a M16 lock nut which is to be tightened with 200
Nm. After having tightened the fastening elements,
secure them using roll pins (5).
Check the welding seams of the
twig breaker for damage and
inspect them for vibration fati-
gue failure when changing the
knives. Secure the fastening of
the breaker using roll pins. Ot-
herwise, the twig breaker may loosen and damage
the crushing elements and/or the chamber. Chips
thrown out are dangerous for the chipper operator!
Caution! The screen and breakers
increase the power demand and
thus may decrease the chipper
output.

• At the bottom, press the discharge pipe against
the connecting piece.
• Carefully tighten the bolt on the lock band to
prevent the pipe from rotating during operation.
Insert the cotter pin.
If the chipper is equipped with an optional discharge
pipe control device, the latter must be mounted on
the chipper before the discharge pipe. First, the cont-
rol device is mounted to the chipper using the lock
band and then the discharge pipe is installed to the
control device as described above.
ADJUSTING THE DISCHARGE PIPE AND LID
• Open the band tightening bolt. Turn the pipe in
the desired direction. Tighten the bolt.
• Adjust the lid by changing the chain length.
Tighten
the lock bands
carefully.
UNSTABLE
When swiveling the long dischar-
ge pipe into the transport/ope-
ration position, exercise extreme
caution.
Please note the force required!
Direct the discharge pipe so that
the thrown out chips do not pose
a risk to the operator of the chip-
per or to or anyone else. Always
keep a safe distance to the di-
scharge position of the chips.

MOUNTING OF THE CHIPPER AND PRE-OPERATION
INSPECTIONS
• For mounting or dismounting the chipper, always
turn o the tractor and apply the parking brake
before entering the area between chipper and
tractor.
• Before connecting the hydraulic hoses, make sure
the hydraulic ports of the tractor are depressu-
rized. Moreover, ensure the correct connection
of the hydraulic supply and return lines on the
tractor.
• Before switching on the electric power supply,
check the plug, the socket and the visible cables
for damage.
• Check the PTO drive shaft for damage and make
sure it has the appropriate length.
• Make sure the connection shields of the PTO drive
shaft are seating correctly and the holding chain
of the connection shields is fastened.
• Make sure all protective and safety devices of the
chipper are installed. Never remove any protective
device during operation.
• Before operation, please make sure there are no
foreign objects in the feed unit.
• Before operation, please make sure there are no
foreign objects in the chipper. Rotate the shaft to
make sure that the cutting disk can rotate freely.
• Make sure that the water drainage holes on the
lower chamber are open and that the disk is not
frozen up.
• During operation, the chipper must stand on level
and hard ground.
• As compared to the tractor, the chipper must not
be lowered excessively. Otherwise, the PTO drive
shaft connection may loosen during operation.
• Direct the discharge pipe so that the thrown out
chips do not pose a risk to the operator of the
chipper or to or anyone else. Always keep a safe
distance to the discharge position of the chips.
STARTING THE CHIPPER
• Start the chipper with caution while operating the
tractor at low speed. Slowly increase the speed
until the required chipping speed has been achie-
ved (540/1000 rpm). CAUTION! Do not exceed the
max. chipper speed of 1000 rpm.
• Now, the chipper is ready for operation.
STOPPING THE CHIPPER
Slow the tractor engine speed to idle before disenga-
ging the PTO. This is especially important with trac-
tors featuring a PTO brake. Turn the PTO control lever
slowly to the OFF position.
When the chipper is shut down,
the cutting disk continues to
rotate - just like a ywheel - after
the PTO has been disengaged.
Please wait until the disk has
stopped completely before
performing any further actions.
The chipper requires approx. 2 ½ minutes to slow
down from maximum speed to complete stop
(1000 rpm -> 0 rpm).
The shaft protection of the chipper is equipped with a
speed monitor which indicates coasting down of the
cutting disk after the PTO has been switched o (see
below gure).

CHIPPING
During chipping, please observe
the following safety instructions:
• Always read the operating and safety instructions
of the used feed unit before operating the chipper.
• The danger zone of the chipper is approx. 20 m.
• Chipper with grab loader feed: During operation,
neither the operator nor other people may stay in
the danger zone. The chipper is operated from the
driver seat in the tractor’s safety cab. Before en-
gaging the tractor PTO and starting the feed unit,
make sure no one is in the chipper’s danger zone.
During operation, the danger zone must be sa-
feguarded to prevent unauthorized people from
entering the danger zone If necessary, operation
must be interrupted. Turn o the feed unit and
disengage the tractor’s PTO before you leave the
safety cab. It is strictly prohibited to manually load
a chipper which is designed for grab loader feed!
• Chipper with manual feed: Never work in front of
the feed hopper. Stand on the left side of the feed
hopper when feeding. During operation, the dan-
ger zone must be safeguarded to prevent unaut-
horized people from entering the danger zone If
necessary, operation must be interrupted.
• The operator of a chipper with manual feed must
wear the following personal protective equip-
ment: safety helmet, ear protection, protective
goggles, cut resistant safety boots and required
protective clothing.
• The operator of a chipper with grab loader feed
must wear an ear protection, cut resistant safety
boots and required protective clothing.
• Never hold any part of the body into the feed hop-
per or into another part of the chipper with the
machine running.
• Before feeding in the material to be chipped,
ensure that the wood fed into the chipper is free
from metal or soil (such as nails, stones, etc.).
• Do not use the chipper at temperatures below
-20 °C. This is to avoid damage due to brittleness
– especially of the knives –caused by the cold.
• Avoid chipping wood that is frozen solid; other-
wise, excessive stress will be exerted on the chip-
per and self-feeding will be impaired.
• FIRE HAZARD! Always keep adequate re-ghting
equipment on hand when using the chipper.
Regularly check the surface temperature of the
chipper. If the chipper suddenly heats up abnor-
mally, stop the chipper and determine the cause
of overheating. Regularly, check the temperature
of the bearings. Pay special attention to careful
maintenance, and keep the chipper free from dust.
If the chipper starts smoking, pour water into the
feed hopper.
STORAGE OF THE CHIPPER
• Before detaching the chipper from the tractor,
park it on level and hard ground. Take appropriate
measures to prevent the chipper from moving or
falling.
• If the chipper is to be stored for a long period,
lubricate the knives e.g. with petroleum jelly.
• Take appropriate measures to keep the water
drainage holes on the lower chamber open.
