tractor has a PTO--brake (for example Ford).
D Check that the PTO shaft is at correct length.
6.1.ASSEMBLY
D Fasten 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 position increases the life of the universal shaft.
If the tractor can not lift the chipper from that position or if the front end of the tractor becomes too
light, then move the lift bar in.
D Tighten the nuts M16 to 260 foot pounds.
6.2.CUTTING THE PTO SHAFT TO THE
CORRECT LENGHT
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
Caution ! of the tractor. If the PTO shaft is too
long it must be cut. Both PTO halves
must be shortened by equal amounts.
D Turn the tractor off. Lower the chipper on a flat
surface.
D Mount the chipper on the three point hitch of the
tractor.
D With the chipper resting on the ground, see that
the splined shafts of the tractor and chipper are
horizontal.
Fig.2.
Guide piece.
D Place the guide piece on the feed opening
D Fasten the feed chute with pin (part 11)
D Connect the discharge tube (29) to the chipper.
Adjust the lid control with the chain.
D The 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
Fig.3.
Mark lenghts.
D Connect 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.

OPERATION
7.OPERATION
7.1.USING THE CHIPPER
Do not attempt to operate this chipper without proper training. Read
and understand the owner’s manual
before operating the machine.
Warning! Failure to heed the warnings printed
on the chipper or in the operators manual might
result in serious injury or death!
D Turn the tractor off.
D Lower the chipper on its legs on a hard, level
surface so it will not tip over.
D Turn 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).
D Look inside feedchute to ensure that it is empty.
D Make sure that all shields are in place and
intact. Removal of the shields is prohibited!
D Direct the discharge tube in desired position.
D The chipper is now ready for use.
D Before feeding make sure that the material is
free from stones, nails and all other foreign
objects.
D When 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.
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 froCaution ! zen solid as they will not self--feed
well.
7.2.TURNING THE CHIPPER OFF
D Reduce 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.
D Start 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.
Danger!

After turning the chipper off, wait for
all movement to stop; the disk continues rotating by flywheel moment
after the PTO has been disconnected.

9.1.BEFORE SERVICING THE KNIVES
03294030
D Remove 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.
ROTATING KNIVES
Don’t risk cutting injury or
being struck by high
speed particles.
Danger !
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.
D Turn the tractor off.
D Open the upper housing bolts M10 (32). Turn
the upper housing to the side.
D Lock the disk with lock bolt (18).
D Remove or turn the feed chute to the side.
D Use protective gloves when handling the kni-ves.

o
30 degree angle.
D Sharpen the knives at a 30 degree angle.
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.
D Remove the 3 locknuts M12 (3.5) behind the
knife frame.
Caution !
Use gloves when removing or handling 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.
D Fasten the knife and tighten the bolts to 50 foot
pounds.
D Adjust 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.

Remove the knife fastening bolts.

9.4.ADJUSTING THE CLEARANCE
BETWEEN KNIVES AND ANVIL
Usually you can sharpen the knives 10 times before
there is a need to adjust the anvil. Adjust the anvil if
the gap to the edge of the knives is over 1/20”.
D Turn the disk so that a knife comes against the
anvil. Move the anvil with the adjusting nuts
(46) until the clearance 1/30 of an inch.
Tighten adjusting nuts. Tighten anvil lock bolts
to 144 foot pounds.
