not transported over people or a location where people
might be.
SHORTENING THE PTO SHAFT
1. Connect the device to the tractor.
2. Measure the distance between the splined shafts
(Distance A)
3. First cut the thicker shaft shield to the correct length
(1). Remember to leave at least a 40 mm clearance.
Then cut a similar length off the profile tube (2).
Shorten the other half of the PTO shaft in the same
way. File o the burr.
4. Interconnect the tubes and check that the shaft as been
shortened enough by moving the machine gently. En-
sure that there is a 40 mm clearance. Also move the
machine sideways to check that the shaft moves free-
ly.

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 be-
fore 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 fro-
zen 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 chip-
per 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 un-
til the required chipping speed has been achieved
(540/1000 rpm). CAUTION! Do not exceed the
max. chipper speed of 1000 rpm.
• Now, the chipper is ready for operation.

CH10 19
STOPPING A TRACTOR-DRIVEN CHIPPER
Slow the tractor engine speed to idle before disengaging
the PTO. This is especially important with tractors featu-
ring 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 conti-
nues rotating like a y-wheel after the
PTO is disengaged. Please wait until
the disk has stopped completely be-
fore 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 extremely
important to slow the driving engine
speed to idle before disconnecting
the hydraulics, to prevent cavitation.

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 safeguar-
ded to prevent unauthorized people from entering
the danger zone. If necessary, operation must be in-
terrupted.
• The operator of a chipper with manual feed must
wear the following personal protective equipment: sa-
fety helmet, ear protection, protective goggles, cut re-
sistant 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, since
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, ensure
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 – espe-
cially of the knives –caused by the cold.
• Avoid chipping wood that is frozen solid; otherwise,
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. Regu-
larly check the surface temperature of the chipper. If
the chipper suddenly heats up abnormally, stop the
chipper and determine the cause of overheating. Re-
gularly, 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.
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 fun-
ctions”.
• Push the material to be chipped into the feed hopper.
Release the material immediately when the feed rol-
lers 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 inc-
reased again, continue feeding by setting the opera-
ting 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 chip-
ping.
