ABOUT THIS MANUAL
This 6700B Operator Safety Manual provides owners and operators of the Peterson 6700B Horizontal Grinder with
information to produce quality, sized material in the safest, best manner known to us. It includes operating instruc-
tions and safety instructions, and is shipped on board each new machine.
The Manual Set
The following information applies to the manuals that
support the 6700B grinder. Described below are the
hazard alert notices you need to follow, the definitions
of special terms, and the text of the limited warranty.
This manual is one in a set that consists of:
•6700B Operator Safety Manual
•6700B Maintenance Manual
•6700B Service Manual (available at extra cost)
•6700B Parts Book
Become thoroughly familiar with these manuals to help
ensure safe, efficient material processing and long
machine life.
Important
Do not remove manuals from the machine. Missing
manuals can lead to hazards and delays when the
manuals are not read or cannot be found by those
who need them
Hazard Alert Messages
Throughout this manual and on decals mounted on the
machine, you will see three types of hazard alert mes-
sages that refer to risks of possible injury to people.
These messages are shown with the following safety
alert symbols:
1DANGER
Indicates an immediate hazard that, if not
avoided, will result in death or serious injury.
1WARNING
Indicates a potential hazard that, if not avoided,
could result in death or serious injury.
1CAUTION
Indicates a potential hazard that, if not avoided,
may result in minor or moderate injury.
Because alert messages can block the flow of a proce-
dure, abbreviated alert messages may appear in the step-
by-step task descriptions.
Important Messages
In addition to the hazard alert messages that refer to pos-
sible injury to people, this manual uses the following
type of alert message:
Important
Indicates a situation which, if not noticed or
avoided, may result in equipment or property dam-
age. This message type is also used to call atten-
tion to opportunities for improving machine
performance or efficiency.

ABOUT THIS MANUAL

Safety Instructions
Be sure to read all the safety information carefully to
avoid hazardous operations and to become aware of
hazards that may arise during maintenance.
Figure ID Numbers
Below each figure in this manual is a number, such as
F05555, in small typeface. This number is for editorial
use only.
Units of Weight and Measure
In this manual, U.S. customary units of weight and mea-
sure are stated first, followed by their SI (metric) values
in parentheses. For example, 10 lb (4.5 kg).
U.S. customary units are sometimes stated in words,
such as inches and gallons. They also appear as abbre-
viations, such as ft for foot or feet, ° F for temperature
degrees Fahrenheit, and in. for inch or inches. Lbs or lb
indicate pounds or pound, and psi indicates pounds per
square inch.
Ft-lb is an abbreviation for “foot-pounds of torque,”
although in some fields the abbreviation lb-ft, for
“pound-feet of torque” is used.
A period (.) after the abbreviation is not included in
most cases, but is retained for the abbreviation of inch
(in.) to avoid confusion with the word “in.”
Many SI units here have been rounded to avoid unnec-
essary precision.

Power Distribution
The power distribution system consists of the:
•Diesel engine, which drives the machine’s hydrau-
lic pumps and hydraulic clutch
•Hydraulic clutch, which drives the rotor drive belt
•Hydraulic system, which delivers power from the
hydraulic pumps to the motors that drive the
machine systems
Engine
The 6700B is equipped with a Caterpillar C27 diesel
engine. An optional C32 engine is available.
The engine powers the:
•Rotor drive belts (through the hydraulic clutch)
•Four hydraulic pumps that power the machine’s
hydraulic motors. The pumps are:
•Feed chain drive pump
•Compression roll drive pump
•Clutch drive pump
•Cooling fan drive pump
The engine has its own electronic monitoring and con-
trol system. Engine performance information can be
viewed on the control panel display (see “Engine Infor-
mation” on page 101).
For easier cold-weather starting, an ether injection sys-
tem is installed on the engine. The engine ECU controls
the timing and amount of ether injected. Operator
involvement is limited to replacing the ether canister.
For detailed engine operation and maintenance infor-
mation, refer to the Caterpillar Operation and Mainte-
nance Manual and the 6700B Maintenance Manual,
provided in the Owner’s Information Package that was
supplied with your 6700B.
Figure 6: Hydraulic Drive Pumps
Hydraulic Clutch
The HP600S hydraulic clutch, which is mounted
directly to a flange on the engine drive shaft, transfers
engine power to the rotor drive belts. Power to operate
the clutch itself is supplied by a PTO-driven hydraulic
pump (Figure 6).
Engine Start: The clutch remains disengaged (rotor
stopped), the feed and discharge systems stay off, and
the material compression system starts in float mode.
Clutch Engage: When the Clutch button is pressed
and held for 3 seconds, the clutch begins to engage
smoothly with controlled slippage to bring the rotor up
to engine speed gradually. The Clutch button blinks
(green) during the engage phase.
Clutch Fully Engaged: When the engine and rotor
drive belt speeds match, the clutch becomes fully
engaged. When engaged, the Clutch button light is
steady (green).

While the engine is running, the clutch senses and com-
pares input and output speeds for engaging, disengag-
ing, and adjusting its performance.
Clutch Disengage: Under normal conditions, the
operator disengages the clutch at the control panel as
part of the machine shut-down procedure. For more
information on clutch operation, see “Clutch Informa-
tion” on page 105.
The hydraulic clutch has its own cooling system,
hydraulic oil filter, and tank (Figure 8).
Hydraulic System
Thehydraulicsystem deliverspowerfromthehydraulic
pumps to the motors that drive the machine systems.
The system consists of:
•Hydraulic motors that power the
•Feed chain
•Compression roll
•Discharge conveyor
•Fans for hydraulic oil cooler and engine radiator
•Two hydraulic cylinders that raises and lowers the
compression roll
•One hydraulic cylinder (normally disconnected
from the anvil housing) that raises the anvilhousing
for maintenance
•Four hydraulic cylinders that fold and unfold the
discharge conveyor
•One cylinder that opens and closes the slide gate on
the feed system
•Two hydraulic cylinders for the landing gear
•Hydraulic control levers
•Hydraulic oil cooler
•Hoses and valves
•Filters (3)
•Main hydraulic oil tank (Figure 7)
•Clutch system (see “Hydraulic Clutch” on page 12)
For more information on the hydraulic system, see
“Hydraulic System Page” on page 107 and “Hydraulic
Fan Page” on page 108.

Machine Controls
Machine controls are located on the control panel and
on the remote transmitter. The control panel receives
power from the battery, with circuit protection provided
by a circuit breaker. The battery disconnect switch turns
power on and off to the control panel.
Battery Disconnect Switch
The Battery Disconnect Switch (Figure 9) provides a
way to connect and disconnect battery power to the
machine controls. To start the engine and operate the
machine, this switch needs to be turned on.
Any time the machine needs to be prevented from start-
ing, turn the Battery Disconnect Switch to the OFF posi-
tion. For safety and security, lock out the switch, as
shown in Figure 10. See also “Machine Lockout/
Tagout” on page 40.
Figure 9: Battery Disconnect Switch (shown in ON position)
Figure 10: Battery Disconnect Switch Locked Out
Circuit Breaker
The control power circuit breaker (Figure 11) protects
the machine from overload in the electrical circuits.
If the machine controls do not operate (control panel
unlit) and the battery disconnect switch is turned on,
check the circuit breaker. If the breaker is tripped
(open), the breaker button extends out. To close the
breaker, push in the button until it snaps into place.

Control Panel
The main operating controls (Figure 12) are mounted in
a lockable cabinet on the radiator (left) side of the
machine.
The control panel is operated from ground level. It con-
tains the following controls (Table 1) as well as the
Peterson Adaptive Control System display screen.
For information about the Peterson display screen, see
“Displaying Machine Information” on page 87.
The controls can be locked out as shown on Figure 10.

Remote Transmitter
You can use the on-machine control panel or the remote
transmitter to operate the 6700B. The remote transmit-
ter (Figure 13) can be carried by hand or in a separate
vehicle, such as a loader, to remotely control many
machine functions. Strong magnets built in to the unit
allow you to attach it to metal surfaces.
1WARNING
Do not rely on the red OFF & STOP button to turn
off the machine.
