9.LIFTING
Lifting points for each machi-
ne are marked with hook sym-
bols.
CAUTION!
Lift only using the proper type of lifting device
and ensure that it has an appropriate lifting ca-
pacity.
Check the lifting slings, cables, and chains re-
gularly.
Ensure that you know the weight of the load to
be lifted and never exceed the lifting capacity
stated by the manufacturer of the lifting device.
Select the transport routes for lifting so that the
load is not transported over people or a locati-
on where people might be.
CH 260 1124 lbs

Fig 3.Lifting point.
10.MOUNTING
10.1.MOUNTING ON A TRACTOR
DAttach the drawbar to the outermost holes
of the chipper in order to use as long a
PTO shaft as possible; this increases the
shaft’s service life.
DMount 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 drawbar to the inner
holes.
DTighten the nuts (M20) to 340 Nm.
DThe hydraulic feeder and mechanical
feeders include fitting blocks that are
installed between the chipper and feeder.
The fitting blocks are installed so that the
two guide pins located at the bottom
section of the feed opening go through the
holes in the fitting block and secure the
block. See Fig. 4.
Fig 4.Installing the fitting block..
DAttach the feed chute, using the pin and
lockscrews, see Fig 5.
Fig 5.Installing the feed shute.
DWhen you work with the chipper, it must be
mounted on a 3---point hitch. The chipper
can tip over if not mounted.
DCheck that the PTO shaft length is correct.
If the PTO shaft supplied with the chipper
cannot be used, contact your local dealer.
For instructions on shortening the PTO
shaft, see Section 10.1.
DCheck that the PTO shaft covers are in
place and that the retaining chain for the
shield is attached.

10.2.CUTTING THE PTO SHAFT TO
THE CORRECT LENGTH
IfthePTOshaftistoolong,
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 short-
ened by equal amounts.
CAUTION!
Cardan shaft recommendation:
Bondioli & Pavesi A6 + (RA1 overrunning
clutch). Walterscheid W2400 + (F3 overrunning
clutch). An overriding clutch must be used if the
tractor has a PTO--brake (for example Ford).
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 chip-
per are horizontal.
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 chipper. Mark lengths required. The tubes
must be shortened so that they cannot reach
the bottom when the chipper is lifted or low-
ered. Cut the plastic shield. See fig.6.--7.
Fig 6.
Fig 7.
DCut a piece from profile tube which is as long
as the piece you cut off from the shield. Short-
en the other PTO shaft by the same length.
After cutting file sharp edges. See fig.8.-- 9.

10.3.INSTALLING THE SCREEN AND
BREAKER
The chipper can be equipped with a twig or
high--power breaker, or alternatively a screen.
The screen cannot be installed in conjunction
with a breaker.
The purpose of breakers is to break chips into
smaller pieces before the chips enter the
discharge pipe.
The screen is used for chipping plastics. The
screen prevents production of excessively large
plastic chips by keeping them from entering the
discharge pipe.
DThe breakers or screen is attached inside
the cover with three M14 bolts (1) and M14
NordLock lock washers (2). Since the bolts
loosen in vibration, they must be tightened
after the first hour of operation and again
after the first day of operation.
The two lowermost fastening bolts are se-
cured by inserting an iron wire (3) through
the holes in the bolt heads. The ends of the
iron wire are twisted with pliers.

Fig. 10.Securing the fastening bolts with iron
wire.
The screen may only be used
for screening thin plastic
pieces.
The screen must be removed
before chipping other
material!
CAUTION!
CAUTION! The screen and breakers increase
the power demand and may decrease chipper
output.

11.OPERATING THE CHIPPER
11.1.INSPECTIONS PRIOR TO
OPERATION
DPark the chipper on level, hard ground.
DStop the tractor’s engine and ensure that the
chipper is fully stopped before carrying out
the inspections.
DCheck that the disk rotates freely by turning
the shaft, and ensure that there are no fo-
reign objects inside the chipper.
DEnsure that all protective devices are intact
and in place. Removal of the covers is prohi-
bited.
DDirect the discharge pipe so that flying chips
do not pose a risk to the operator or anyone
else.
11.2.STARTING THE CHIPPER
DStart the chipper at low tractor engine speed
and increase the speed slowly to the requi-
red chipping speed (540/1,000 rpm).
DThe chipper is now ready for chipping.
11.3.STOPPING A TRACTOR --- DRIVEN
CHIPPER
DSlow the tractor engine speed to idle before
disengaging the PTO. This is especially im-
portant with tractors featuring a PTO brake
(e.g., Ford). Turn the PTO control lever slow-
ly to the OFF position.
11.4.STOPPING A HYDRAULIC MO
TOR DRIVEN CHIPPER
DIMPORTANT! When the chipper is driven by
the HD100, it is extremely important to slow
the driving engine speed to idle before di-
sconnecting the hydraulics, to prevent cavi-
tation.
Never disconnect the hydrau-
lics from high rpm. This will
cause a risk of cavitation and
may damage the hydraulic mo-
tor.
Check that no sounds indica-
ting cavitation can be heard
from the hydraulic motor.
CAUTION!
After stopping the chipper, wait
for all movement to stop. The
disk continues rotating like a
flywheel after the PTO is disen-
gaged.
DANGER!
11.5.CHIPPING
DBefore feeding in the material to be chipped,
ensure that the wood is free from nails, sto-
nes, etc.
DFeed the wood from a standing position on
the left side of the feeder.
DPush the wood inside the feed chute until
chipping starts. Let go of the wood as soon
as the self---feeding starts.
DIf you are using a hydraulic feeder, refer to
the separate chipping instructions in the fee-
der manual.
Do not use the chipper in tem-
peratures below -- 20_C. This is
to avoid damage due to brittle-
ness – especially in the knives –
caused by the cold. Avoid chip-
ping wood that is frozen solid,
as self-- feeding is reduced in
this case.
CAUTION!
ROTATING KNIVES!
Knives can cause cutting inju-
ry.
Do reach inside the feed chute
with hands or feet.
DANGER!

per heats up abnormally, stop
the chipper and determine the
cause of the overheating.
Check the temperature of
bearings regularly.
Pay special attention to careful
maintenance, and keep the
chipper free from dust.
If the chipper starts smoking,
pour water down the feed
chute.
WARNING !
11.6.ADJUSTING THE DISCHARGE
PIPE AND LID
Kuva 12. Dicharge pipe and lid movements.
DOpen the band tightening bolt. Turn the
pipe in the desired direction. Tighten the
bolt.
DAdjust the lid by changing the chain
length.
Never direct the discharge
pipe or lid towards the feeding
area or drive machine.
CAUTION!
12.STORAGE
DEnsure that the chipper is on solid ground
and that it cannot tip over.
DIf the chipper is to be stored for a long period,
lubricate the knives with, for example, petro-
leum jelly.
DEnsure that the water drainage holes in the
lower chamber are unobstructed.

Park the chipper on hard, level ground to
avoid it falling over.
Wear protective gloves when handling
knives or anvils.
WARNING!
13.1. LUBRICATING THE BEARINGS
DThe bearings are lubricated at the factory,
and a similar lubricant should be used for
subsequent lubrication (Shell Alvania Grea-
se R 3. or Kendall L427). An excessive amo-
unt of grease causes overheating and im-
pairs lubrication.
DLubricate the bearings every 200 working
hours or at least once a year.
DLubricate the bearings with ball bearing
grease weekly when the chipper is in use.
Otherwise, lubricate at least once a year.
See Fig. 13.

and regularly, as shown in Fig. 14..
DLubricate the inner surface of the PTO shaft,
accessed via the outer profile tube.
DLubricate the shield tubes in wintertime to
prevent them from freezing and sticking.
