6.ASSEMBLY AND MOUNTING
6.1.ASSEMBLY
DFasten the 3--point hitch lift bar with screw M16
(part 13 and 15, see spare parts list 03294030) to
the chipper frame. Try first the holes that move the
chipper farther away from the tractor. That posi-
tion increases the life of the universal shaft.
If the tractor can not lift the chipper from that posi-
tion or if the front end of the tractor becomes too
light, then move the lift bar in.
DTighten the nuts M16 to 260 foot pounds.
Fig.2. Guide piece.
DPlace the guide piece on the feed opening
DFasten the feed chute with pin (part 11)
DConnect the discharge tube (29) to the chipper.
Adjust the lid control with the chain.
DThe chipper must be mounted on the 3--point
hitch of the tractor. The chipper will tip over if it
is run without hooking it up to the 3--point hitch.
Cardan shaft recommendation:
Bondioli & Pavesi A6 + FF2 overload clutch + RA1
overrunning clutch or Walterscheid W2400 +
K92/4 (D) overload clutch + F3 overrunning
clutch. An overriding clutch must be used if the
tractor has a PTO--brake (for example Ford).
DCheck that the PTO shaft is at correct length.
6.2.CUTTING THE PTO SHAFT TO THE
CORRECT LENGHT
Caution !
If the PTO shaft is too long it might
bind when the three point hitch is lifted
up. Damage might be caused to the
bearings of the chipper or to the PTO
of the tractor. If the PTO shaft is too
long it must be cut. Both PTO halves
must be shortened by equal amounts.
DTurn the tractor off. Lower the chipper on a flat
surface.
DMount the chipper on the three point hitch of the
tractor.
DWith the chipper resting on the ground, see that
the splined shafts of the tractor and chipper are
horizontal.
Fig.3. Mark lenghts.
DConnect one shaft half to the chipper‘s PTO
and the other half at the tractor‘s PTO. Lay the
other PTO half on its side so that the end of the
shaft is one inch from the PTO--end of the chip--
per. Mark lengths required. The tubes must be
shortened so that they cannot reach the bottom
when the chipper is lifted or lowered.

7.OPERATION
7.1.USING THE CHIPPER
Warning!
Do not attempt to operate this chip-
per without proper training. Read
and understand the owner’s manual
before operating the machine.
Failure to heed the warnings printed
on the chipper or in the operators manual might
result in serious injury or death!
DTurn the tractor off.
DLower the chipper on its legs on a hard, level
surface so it will not tip over.
DTurn the chipper’s axle by hand to ensure that
the disk can turn freely (so that there are no for--
eign objects in the chipper).
DLook inside feedchute to ensure that it is empty.
DMake sure that all shields are in place and
intact. Removal of the shields is prohibited!
DDirect the discharge tube in desired position.
DStart up the PTO when the tractor runs at low
rpm and increase the rpm to operating speed.
Power required depends on the material to be
chipped and the sharpness of the knives.
DThe chipper is now ready for use.
DBefore feeding make sure that the material is
free from stones, nails and all other foreign
objects.
DWhen chipping wood, push the tree trunk inside
the feed chute until the knives touch the tree.
The chipper is self feeding, so let go of the tree
as soon as the knives touch it.
Caution !
Do not use chipper if temperature
falls below 23_F. This practice will
prevent risk of damage to the knives.
Also avoid chipping trees that are fro-
zen solid as they will not self--feed
well.
7.2.TURNING THE CHIPPER OFF
DReduce the tractor rpm to idle before shifting
the PTO to OFF--position. This is particularly
important on tractors with PTO brakes, such as
Ford.
On these tractors, after idling the tractor, you
should slowly move the PTO control lever to the
OFF--position.
Danger!
After turning the chipper off, wait for
all movement to stop; the disk contin-
ues rotating by flywheel moment
after the PTO has been discon-
nected.

8.SERVICE
8.1.TIGHTENING THE CLUTCH
If the P.T.O clutch slips during normal operation,
it must be tightened.
DThe clutch is tightened by tightening the nuts
which press on the clutch springs.
DTighten every nut 1/4 of a turn.
DTry out the chipper.
8.2.PERIODIC SERVICE
Warning !
Always disengage the PTO and turn
the tractor OFF before you service or
repair the chipper.
Wait for all movement to stop before
reaching inside the feed chute.
Remove the keys so that the tractor
cannot be started up accidentally.
DAlways turn the tractor off before servicing or
repairing the chipper. Wait for all movement to
stop before service; the disk continues rotating
by flywheel moment after the PTO has been
disconnected.
DOpen the upper housing bolts M10 (32).
DLock the disk with the lock bolt (18).
DRemove or turn the feed chute to the side.
The bearings are greased at the factory with Shell
Alvania Grease R 3. A similar lubricant such as
Kendall L427 should be used by you. Avoid over-
greasing because it causes heat which reduces
lubrication.
DLubricate bearings every 200 hours or once a
year.
DCheck that the clearance between the knives
and the anvil is about 1/30 ”. See chapter 9.4.
DIf the chipper stands unused for long periods of
time, cover the knives with grease.
Make sure that the water drains on the lower
housing are open.

8.3.LUBRICATION OF THE PTO
SHAFT
DLubricate the P.T.O shaft before putting into
operation and frequently as shown in
schema below.
DApply grease to inside of outer telescopic
profile.
DWhen used in winter the guard tubes must be
greased to prevent them from freezing solid.

9.KNIVES AND ANVIL
9.1.BEFORE SERVICING THE KNIVES
Danger !
ROTATING KNIVES
Don’t risk cutting injury or
beingstruckbyhigh
speed particles.
Wait for all movement to
stop before reaching inside the feed chute.
Failure to follow safety precautions could result
in serious personal injury or death.
DTurn the tractor off.
DOpen the upper housing bolts M10 (32). Turn
the upper housing to the side.
DLock the disk with lock bolt (18).
DRemove or turn the feed chute to the side.
DUse protective gloves when handling the kni--
ves.
9.2.SHARPENING THE KNIVES
You will notice the need to sharpen the knives
when:
-- Trees do not self--feed well.
-- The power requirement is increased.
-- The smoothness of the chip surface is decrea--
sed.
Keep the knives with their original pairs. That way
the knives will be worn equally and the disk stays
in balance.
DRemove the 3 locknuts M12 (3.5) behind the
knife frame.
Fig.9. Remove the knife fastening bolts.
DRemove the knife--fastening bolts M12 (3.3,
they are threaded through the disk. Turn the
wrench so that your knuckles will not touch the
knife if the wrench slips.

o
Fig.10. 30 degree angle.
DSharpen the knives at a 30 degree angle.
Caution !
Use gloves when removing or han-
dling the knives, Turn the wrench so
that your knuckles will not touch the
knife if the wrench slips.
Avoid getting the knife hot when sharpening.
Sharpen both of the knives the same amount.
Certain corn choppers use the same style of knife
as the Valby Chipper (Papec for example).
Automatic grinders to service this style of knife
can thus be found at some implement dealers. Of
course, grinders to service chipper knives are
available from grinder and knife manufacturers.
DFasten the knife and tighten the bolts to 50 foot
pounds.
DAdjust anvil clearance if needed.
9.3.SHARPENING THE ANVIL
If you notice wear or rounding of the inner edge of
the anvil, sharpen the anvil so that the original
angles are retained.
