MOUNTING OF THE CHIPPER AND PRE-OPERATION
INSPECTIONS
1. For mounting or dismounting the chipper, always
turn o the tractor and apply the parking brake
before entering the area between chipper and
tractor.
2. Check the PTO drive shaft for damage and make
sure it has the appropriate length.
3. Make sure the connection shields of the PTO drive
shaft are seating correctly and the holding chain
of the connection shields is fastened.
4. Make sure all protective and safety devices of the
chipper are installed. Never remove any protective
device during operation.
5. Before operation, please make sure there are no
foreign objects in the feed hopper.
6. 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.
7. Make sure that the water drainage holes on the
lower chamber are open and that the disk is not
frozen up.
8. During operation, the chipper must stand on level
and hard ground.
9. As compared to the tractor, the chipper must not
be lowered excessively. Otherwise, the PTO drive
shaft connection may loosen during operation.
10. 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.

DANGER!
STOPPING A TRACTOR-DRIVEN CHIPPER
Slow the tractor engine speed to idle before disenga-
ging the PTO. This is especially important with tractors
featuring a PTO brake (e.g., Ford). Turn the PTO control
lever slowly to the OFF position.
After stopping the chipper, wait
for all movement to stop. The
disk continues rotating like a y-
wheel after the PTO is disengaged.
Please wait until the disk has
stopped completely before
performing any further actions.
The chipper requires approx. 1 ½ minutes to slow
down from maximum speed to complete stop
(1000 rpm -> 0 rpm).
STOPPING A HYDRAULIC MOTOR DRIVEN CHIPPER
IMPORTANT! When the chipper
is driven by the HD 50, it is extre-
mely important to slow the dri-
ving engine speed to idle before
disconnecting the hydraulics, to
prevent cavitation.
CAUTION!

STOP
CHIPPING
During chipping, please observe
the following safety instructions:
• The danger zone of the chipper is approx. 20 m.
• During operation, the danger zone must be sa-
feguarded to prevent unauthorized 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.
• Never work in front of the feed hopper. Stand on
the left side of the feed hopper when feeding, sin-
ce the feed rollers may push the wood upwards or
to the right.
• Never hold any part of the body into the feed
hopper or into another part of the chipper with
the machine running.
• Make sure that loose clothing or long hair cannot
be caught by rotating machine parts or by the
material to be fed.
• Before feeding in the material to be chipped, en-
sure that the wood fed into the chipper is free
from metal or soil (such as nails, stones, etc.).
• Never feed ropes or barbed wire to the chipper
since these could get caught on the operator’s
body and draw him into the feed hopper.
• 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; otherwi-
se, excessive stress will be exerted on the chipper
and self-feeding will be impaired.
• FIRE HAZARD! Always keep adequate re-ghting
equipment on hand when using the chipper. Re-
gularly check the surface temperature of the chip-
per. If the chipper suddenly heats up abnormally,
stop the chipper and determine the cause of over-
heating. Regularly, check the temperature of the
bearings. Pay special attention to careful mainte-
nance, and keep the chipper free from dust. If the
chipper starts smoking, pour water into the feed
hopper.
OPERATION OF CHIPPER AND FEED UNIT
• Start the chipper. Caution! See section ”Starting
the chipper”.
• Set the operating lever to the FEED FORWARD F
position. Caution! See picture ”Operating lever
functions”.
• Push the material to be chipped into the feed hop-
per. Release the material immediately when the
feed rollers start to rotate.
• When chipping large trunks or the like, the rotary
speed of a low-power tractor often drops during
chipping very long wood pieces. Temporarily stop
feeding by setting the operating lever to the STOP
position. After the rotary speed has suciently
increased again, continue feeding by setting the
operating lever to the FEED FORWARD F position.
Oil will heat when travelling
through the hydraulic pump,
hydraulicmotor and the valves.
The heating can be considerable
if the tractor has a small hydraulic
tank.
Check the oil temperatures twice an hour to prevent
the oil from overheating. If the oil overheats, let it
cool down by stopping the chipping.

8. Install the securing ring with the claws facing out-
wards and the inside claw in the groove of the
tightening cone, and install the axle nut.
9. The inner ring of the bearing should press tightly
against the tightening cone.
10. Tighten the axle nut with a hook spanner until the
bearing is tightly on the cone, or to 80 Nm. Ho-
wever, the outer ring of the bearing should turn
freely. Note the location of the tightening cone on
the shaft.
11. Bend one claw of the securing ring (3) into a
notch on the axle nut.
12. Install the other half of the dust cover and end pla-
te on the bearing housing. Install the spacer ring
(4) on the shaft.
13. Lower the disk to the bearing housing.
14. Attach the other half of the dust cover to the up-
per bearing housing; install the upper bearing
housing fastening bolts and tighten to 50 Nm.
15. Lubricate the bearing housing. An excessive
amount of grease causes overheating and impairs
lubrication.
The bearings at the feeder side and splined shaft
side are dierent from each other. The bearing at the
splined shaft side, Fig. 7b., does not have spacer rings
(4 and 9) and an end plate (1). The bearing at the splin-
ed shaft side has dust covers on both sides (11).
