messages that refer to risks of possible injury to people.
These messages are shown with the following safety
alert symbols:
1DANGER

avoided, will result in death or serious injury.
1WARNING
Indicates a potential hazard that, if not avoided,
could result in death or serious injury.

Important Messages and
Notes
In addition to the hazard alert messages that refer to pos-
sible injury to people, the 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.
NOTE: Provides additional information to enhance
understanding of the topic.
Safety Instructions
Be sure to read the entire Safety chapter (“Working
Safely” on page 31) to avoid hazardous operations and
to become aware of hazards that may arise during main-
tenance.
Small Numbers on Figures
In Peterson product manuals, we insert a number, such
as F05555, in small typeface below each graphic to
identify its file name. 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). Many SI
units here have been rounded to avoid an improper
appearance of precision.
U.S. customary units are sometimes stated in words, or
as abbreviations, such as ft for foot or feet, °F for tem-
perature degrees Fahrenheit, and in. for inch or inches,
lbs for pounds, and psi for 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.

Power Distribution
The engine drives two power distribution systems:
•Hydraulic clutch and drive belts for the grinder
rotor.
•Hydraulic pumps for the hydraulic motors, cylin-
ders, and drive tracks.
Engine
The 6710D is equipped with a Caterpillar C32 diesel
engine, with a PTTech HPTO15 (hydraulic power take
off) clutch.
The engine includes an ECM (electronic control mod-
ule) that communicates with the Peterson Adaptive
Control System. The ECM monitors engine perfor-
mance that can be viewed on the control panel display.
Machines sold in the U.S. include engines with a Tier 4
aftertreatment. Machines sold outside the U.S. may
include a Tier 2 engine that does not include the after-
treatment.
For detailed engine operation and maintenance infor-
mation, refer to the Caterpillar Operation and Mainte-
nance Manual, provided in the Owner’s Information
Package,andthe6710DMaintenanceManual,storedin
the document box onboard your 6710D.
Hydraulic Clutch
When the engine starts, the clutch remains disengaged
until the operator presses the CLUTCH control button on
the control panel.
Engaging: The clutch may be engaged when the
engine speed is between 750–1000 rpm.
During the engage cycle, the clutch provides controlled
slippage to bring the rotor up to engine speed gradually.
When the engine and rotor speeds match, the clutch
becomes fully engaged.
Operating: When the clutch is fully engaged, the
greenringaroundtheCLUTCH button andagreen clutch
icon on the display are illuminated.
While the engine is running, the clutch controller senses
and compares input and output speeds for engaging, dis-
engaging, and adjusting clutch performance.
Disengaging: The clutch should be disengaged
before shutting down the engine. For instructions on
operating the clutch, see “Engaging the Clutch” on
page 72.
The clutch controller monitors clutch conditions. When
a condition exists that may cause damage to the clutch,
the clutch may either disengage or fail to engage.
Failure to Engage–Possible Causes
The following are some causes of an automatic disen-
gagement or a failure to engage:
•High oil temperature or clogged filter
•Engine speed too low or too high
•Shock load causing engine speed to drop below 500
rpm
•Overload on the clutch (clutch slippage)
•Previous overload not yet cleared
•Pushing the CLUTCH button while clutch is in the
process of engaging
•Increasing engine speed while clutch is in the pro-
cess of engaging
•Trying to re-engage clutch when the grinder is mov-
ing too fast
For details on clutch faults, see “Clutch Fault Mes-
sages” on page 132.

Hydraulics
Hydraulic pressure-compensated, load-sense pumps
and valves distribute power to several machine assem-
blies:
•Direct drive hydraulic motors power the following
units:
•Feed conveyor
•Compression roll
•Discharge conveyor
•Drive tracks
•One hydraulic cylinder raises and lowers the com-
pression roll. The linkage to this cylinder can be
reconfigured to lift the anvil housing for mainte-
nance.
•Two hydraulic cylinders fold and unfold the dis-
charge conveyor.
•One cylinder opens and closes the slide gate on the
feed system.
The hydraulic oil tank (separate from the clutch oil
tank) includes a sight gauge and fill cap. The suction
line contains a ball valve that must remain open when-
ever the engine runs.

Machine Controls
Machine controls are located on the control panel and
on the remote transmitter. The control panel is powered
by the batteries. Circuit protection is provided by circuit
breakers. Power shut-off is provided by the disconnect
switches.
A gateway device is installed on the outside of the con-
trol box for the Remote Monitoring option. The gate-
way enables a wireless link for transmittinginformation
from the MD4 controller.
Electrical Disconnect
Switches
The 6710D is equipped with two switches to connect
and disconnect battery electrical power (Figure 6 on
page 14):
•Control power disconnect switch to disconnect
electrical power to all systems except the work
lights and the water sprayer system.
•Battery disconnect switch to disconnect all electri-
cal power.
For detailed informationon the disconnectswitchesand
lockout procedures, see “Disconnect Switches” on
page 33.
1WARNING
Personal injury hazard. Electrical hazard.
Unauthorized operation and electrical accidents
are possible when a machine is left unattended
with the electrical power enabled. Disconnect
electrical power at the battery disconnect
switch:
• Overnight and on weekends
• Whenever the operator is away
• During transport
Always use the battery disconnect to turn off the electri-
cal system.
Exception: if the work lights or the water sprayer are
required for maintenance, then use the control power
disconnect.
Follow “lockout/tagout” procedures with either switch.
See “Disconnect Lockout/Tagout” on page 34.
Circuit Breakers
Circuit breakers protect the electrical circuits. They are
locatedinthepowerdistributionbox.Ifacircuitbreaker
trips, determine the cause. To reset a breaker, first open
the control power disconnect, push in the button on the
breaker, then close the control power disconnect.
If both of the electrical disconnect switches are turned
on, but the machine controls do not operate and the con-
trol panel is unlit, check the CONTROL POWER CIRCUIT
BREAKER (Figure 6). The button on a tripped breaker
extends out. Push it back in until it snaps into place.
For more information on circuit breakers and the power
distribution box, see the Electrical section in the 6710D
Maintenance Manual.
