Area 3:
Truck Loading and Haul-away Zone
This area is for loading trucks. Trucks pull in to be filled
with finished material, stop or move slowly forward
while being loaded, and then exit.
Area 4:
Falling-material Hazard Zone and Loader
Access Zone
This is the area where the loader operator is most active
in delivering raw material to feed into the hopper. The
6710D can be fed from either side. The possibility of
hazardous flying objects exists in this area. Any autho-
rized person needing to enter this area while the
machine is operating should make positive contact with
the loader operator and machine operator before enter-
ing the zone. Unauthorized personnel should not enter.
Be alert and reactive to any person or machine entering
this area. Before start-up, check this area to be sure all
people are at a safe distance.
Sometimes larger pieces of material being fed into the
hopper can fall from the loader and tumble past the hop-
per walls.
Many areas in a storage yard contain piles of raw or
unprocessed feed material awaiting processing. Also,
piles of finished materials are present. These piles block
views and can interfere with communications. Care and
attention are needed at all times to avoid accidents.
Noise levels, moving parts hazards, and machine activ-
ity, including loaders and trucks entering and leaving,
all combine in this area to make it a zone that requires
attention to safety hazards. Only qualified and autho-
rized personnel should enter this zone. No one should
enter area without specific permission from the machine
operator.
Area 5:
Crushing, Pinching, and Trapping Hazard
Zone
This area is near the feed chain. Stay away from the feed
chain when the engine is running. Never attempt to
load, unload, or remove material by hand from the feed
chain. Avoid flying material hazards.
The feed may reverse without warning. Normal opera-
tions include automatic reversing of the feed chain. As
a result, the feed chain may reverse suddenly, without
warning and material may spill out the end of the hop-
per.
Crushing, pinching, and possible trapping hazards also
exist in this area near the feed chain and on each side of
the feed hopper at the front of the machine.
Area 6:
Flying-material Hazard Zone (Figure 42 on
To reduce risk of being hit by flying or falling material,
avoid this area while operating. This area is where
thrown materials, such as wood chunks, knots, and
other objects in the feed, sometimes land.

CAUTION
The tracked 6710D can rapidly change position
and direction, making related, rapid changes in
the hazard zone. This zone applies whenever the
machine is operating and the rotor is turning.
This zone extends out 300 feet (100 meters) in the direc-
tion of the feed hopper from the rotor. It also extends
about 45 feet (15 meters) wide near the machine.
When buildings, people, or other items are in the area,
you must keep the machine positioned to point the haz-
ard zone away from those things.
Materials can be thrown or ejected throughout this
entire U-shaped area at any time during operation.
However, when the hopper is full of material, such ejec-
tions are rare. Ejected materials are unlikely to fall or to
be thrown even within the U-shaped zone when the bit
exposure area of the rotor is covered by material in the
hopper or by the compression roll.
Be very careful to stay out of the thrown material hazard
zone unless you are in the protective cab of a heavy-
duty vehicle.
Outside the thrown material hazard zone, forceful ejec-
tion of material is rare, but true safe zones depend on
operator actions and experience with actual conditions.
The areas inside the U-shaped zones shown in
Figure 42Figure 42 on page 56 represents a minimal
hazard zone for land clearing or construction and dem-
olition grinding, where scrap in the feed material is
common. Poor maintenance of the rotor and bit assem-
blies can cause worn bolts to fail and metal parts to be
thrown from the machine. Keep at least 300 feet (100
meters) away from machine in the area of the thrown
material hazard zone when the machine is operating. To
