CHIPPING
During chipping, please observe the
following safety instructions:
WARNING
•
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 fire-fighting
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 sufficiently 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
IMPORTANT
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.
