This section includes a discussion of gauges,
switches, machine controls, attachment controls,
transportation and towing information.
Photographs and illustrations guide the operator
through correct procedures of checking, starting,
operating and stopping the machine.
Operating techniques outlined in this publication are
basic. Skill and techniques develop as the operator
gains knowledge of the machine and its capabilities.
Maintenance Intervals
Use the service hour meter to determine servicing
intervals. Calendar intervals shown (daily, weekly,
monthly, etc.) can be used instead of service hour
meter intervals if they provide more convenient
servicing schedules and approximate the indicated
service hour meter reading. Recommended service
should always be performed at the interval that
occurs first.
Under extremely severe, dusty or wet operating
conditions, more frequent lubrication than is specified
in the maintenance intervals chart might be
necessary.
Perform service on items at multiples of the original
requirement. For example, at every 500 service hours
or 3 months, also service those items listed under
every 250 service hours or monthly and every 10
service hours or daily.
California Proposition 65 Warning
Diesel engine exhaust and some of its constituents
are known to the State of California to cause cancer,
birth defects, and other reproductive harm.

characters. In an effort to provide uniform equipment
identification, Caterpillar and other construction
equipment manufacturers are moving to comply with
the latest version of the product identification
numbering standard. Non-road machine PINs are
defined by ISO 10261. The new PIN format will apply
to all Cat machines and generator sets. The PIN
plates and frame marking will display the 17 character
PIN. The new format will look like the following:
5
Foreword
Illustration 1 g00751314
Where:
1. Caterpillar's World Manufacturing Code (characters
1-3)
2. Machine Descriptor (characters 4-8)
3. Check Character (character 9)
4. Machine Indicator Section (MIS) or Product
Sequence Number (characters 10-17). These were
previously referred to as the Serial Number.
Machines and generator sets produced before First
Quarter 2001 will maintain their 8 character PIN
format.
Components such as engines, transmissions, axles,
etc. and work tools will continue to use an 8 character
Serial Number (S/N).

use appropriate devices such as ladders or man lift
machines. If Equipped, use the machine anchorage
points and use approved fall arrest harnesses and
lanyards.
Pressure Air and Water
Pressurized air and/or water can cause debris and/or
hot water to be blown out. The debris and/or hot
water could result in personal injury.
When pressurized air and/or pressurized water is
used for cleaning, wear protective clothing, protective
shoes, and eye protection. Eye protection includes
goggles or a protective face shield.
Illustration 39 g00702020

Make sure that all protective guards and all covers
are secured in place on the equipment.
Keep the equipment free from foreign material.
Remove debris, oil, tools, and other items from the
deck, from walkways, and from steps.
The maximum air pressure for cleaning purposes
must be reduced to 448 kPa (65 psi) when the nozzle
is deadheaded and the nozzle is used with an
effective chip deflector and personal protective
equipment. The maximum water pressure for
cleaning purposes must be below 448n kPa (65 psi).
Avoid direct spraying of water on electrical
connectors, connections, and components. When
using air for cleaning, allow the machine to cool to
reduce the possibility of fine debris igniting when redeposited on hot surfaces.
Trapped Pressure
Secure all loose items such as lunch boxes, tools,

Inhaling the fumes that are released from a flame that
contacts air conditioner refrigerant can cause bodily
harm or death. Inhaling gas from air conditioner
refrigerant through a lighted cigarette can cause
bodily harm or death.
Never put maintenance fluids into glass containers.
Drain all liquids into a suitable container.
Obey all local regulations for the disposal of liquids.
Use all cleaning solutions with care. Report all
necessary repairs.
Do not allow unauthorized personnel on the
equipment.
Unless you are instructed otherwise, perform
maintenance with the equipment in the servicing
position. Refer to Operation and Maintenance Manual
for the procedure for placing the equipment in the
servicing position.
Pressure can be trapped in a hydraulic system.
Accumulators in a hydraulic system will store
pressure. Allow a sufficient amount of time for the
pressure that is stored in the accumulators to be
released. Releasing trapped pressure can cause
sudden machine movement or attachment
movement. Use caution if you disconnect hydraulic
lines or fittings. High-pressure oil that is released can
cause a hose to whip. High-pressure oil that is
released can cause oil to spray. Fluid penetration can
cause serious injury and possible death.
Fluid Penetration
Pressure can be trapped in the hydraulic circuit long
after the engine has been stopped. The pressure can
cause hydraulic fluid or items such as pipe plugs to
escape rapidly if the pressure is not relieved correctly.
Do not remove any hydraulic components or parts
until pressure has been relieved or personal injury
may occur. Do not disassemble any hydraulic
components or parts until pressure has been relieved
or personal injury may occur. Refer to the Service
Manual for any procedures that are required to relieve
the hydraulic pressure.

Prentice equipment and replacement parts that are
shipped from Caterpillar are asbestos free. Prentice
recommends the use of only genuine Prentice
replacement parts. Use the following guidelines when
you handle any replacement parts that contain
asbestos or when you handle asbestos debris.
Use caution. Avoid inhaling dust that might be
generated when you handle components that contain
asbestos fibers. Inhaling this dust can be hazardous
to your health. The components that may contain
asbestos fibers are brake pads, brake bands, lining
material, clutch plates, and some gaskets. The
asbestos that is used in these components is usually
bound in a resin or sealed in some way. Normal
handling is not hazardous unless airborne dust that
contains asbestos is generated.
If dust that may contain asbestos is present, there are
several guidelines that should be followed:

Crushing Prevention and Cutting Prevention
• Never use compressed air for cleaning.
• Avoid brushing materials that contain asbestos.
• Avoid grinding materials that contain asbestos.
• Use a wet method in order to clean up asbestos
materials.
• A vacuum cleaner that is equipped with a high
efficiency particulate air filter (HEPA) can also be
used.
• Use exhaust ventilation on permanent machining
jobs.
• Wear an approved respirator if there is no other
way to control the dust.
• Comply with applicable rules and regulations for
the work place. In the United States, use
Occupational Safety and Health Administration
(OSHA) requirements. These OSHA requirements
can be found in “29 CFR 1910.1001”.
• Obey environmental regulations for the disposal of
asbestos.
• Stay away from areas that might have asbestos
particles in the air.

allowed to accumulate, the debris can rapidly become
fuel the fuel component of a machine fire. Clean all
accumulations of forest debris in the engine
compartment or around other hot areas and hot parts
upon completion of each work shift. Clean more
frequently when working conditions where large
amounts of debris are present.
Do not operate the machine near any flame.
Keep shields in place. Exhaust shields (if equipped)
protect hot exhaust components from oil spray or fuel
spray in case of a break in a line, in a hose, or in a
seal. Exhaust shields must be installed correctly.
Do not weld or flame cut on tanks or lines that contain
flammable fluids or flammable material. Empty and
purge the lines and tanks. Then clean the lines and
tanks with a nonflammable solvent prior to welding or
flame cutting. Ensure that the components are
properly grounded in order to avoid unwanted arcs.
Dust that is generated from repairing nonmetallic
hoods or fenders may be flammable and/or explosive.
Repair such components in a well ventilated area
away from open flames or sparks. Use suitable
Personal Protection Equipment (PPE).
Inspect all lines and hoses for wear or deterioration.
Replace damaged lines and hoses. The lines and the
hoses should have adequate support and secure
clamps. Tighten all connections to the recommended

Page 25
SEBU8705 25
Safety Section
Fire Prevention and Explosion Prevention
Do not operate a machine if battery cables or related
parts show signs of wear or damage. Contact your
Prentice dealer for service.
Follow safe procedures for engine starting with jumpstart cables. Improper jumper cable connections can
cause an explosion that may result in injury. Refer to
Operation and Maintenance Manual, “Engine Starting
with Jump Start Cables” for specific instructions.
Do not charge a frozen battery. Explosions may
occur.
Gases from a battery can explode. Keep any open
flames or sparks away from the top of a battery. Do
not smoke in battery charging areas.
Never check the battery charge by placing a metal
object across the terminal posts. Use a voltmeter in
order to check the battery charge.
Daily inspect battery cables that are in areas that are
visible. Inspect cables, clips, straps, and other
restraints for damage. Replace any damaged parts.
Check for signs of the following, which can occur over
time due to use and environmental factors:
• Fraying
• Abrasion
• Cracking
• Discoloration
Fire on a machine can result in personal injury or
death. Exposed battery cables that come into contact with a grounded connection can result in
fires. Replace cables and related parts that show
signs of wear or damage. Contact your Prentice
dealer.
Wiring
Check electrical wires daily. If any of the following
conditions exist, replace parts before you operate the
machine.
• Fraying
• Signs of abrasion or wear
• Cracking
• Discoloration
• Cuts on insulation
• Other damage
Make sure that all clamps, guards, clips, and straps
are reinstalled correctly. Doing so will help to prevent
vibration, rubbing against other parts, and excessive
heat during machine operation.
• Cuts on the insulation of the cable
• Fouling
• Corroded terminals, damaged terminals, and loose
terminals
Replace damaged battery cable(s) and replace any
related parts. Eliminate any fouling, which may have
caused insulation failure or related component
damage or wear. Ensure that all components are
reinstalled correctly.
An exposed wire on the battery cable may cause a
short to ground if the exposed area comes into
contact with a grounded surface. A battery cable
short produces heat from the battery current, which
may be a fire hazard.
An exposed wire on the ground cable between the
battery and the disconnect switch may cause the
disconnect switch to be bypassed if the exposed area
comes into contact with a grounded surface. Doing so
may result in an unsafe condition for servicing the
machine. Repair components or replace components
before servicing the machine.
Attaching electrical wiring to hoses and tubes that
contain flammable fluids or combustible fluids should
be avoided.
Consult your Prentice dealer for repair or for
replacement parts.
Keep wiring and electrical connections free of debris.

can cause serious injury and possible death. A pin
hole leak can cause severe injury. If fluid is injected
into your skin, you must get treatment immediately.
Seek treatment from a doctor that is familiar with this
type of injury.
Replace the affected parts if any of the following
conditions are present:
• End fittings are damaged or leaking.
• Outer coverings are chafed or cut.
• Wires are exposed.
• Outer coverings are swelling or ballooning.
• Flexible parts of the hoses are kinked.
• Outer covers have exposed embedded armoring.
• End fittings are displaced.
Make sure that all clamps, guards, and heat shields
are installed correctly. During machine operation,
doing so will help to prevent vibration, rubbing against
other parts, excessive heat, and failure of lines,
tubes, and hoses.
Dispose of used ether cylinders properly. Do not
puncture an ether cylinder. Keep ether cylinders away
from unauthorized personnel.
Fire Extinguisher
As an additional safety measure, keep a fire
extinguisher on the machine.

Tire Information
SMCS Code: 7000
Explosions of air inflated tires have resulted from
heat-induced gas combustion inside the tires.
Explosions can be caused by heat that is generated
by welding, by heating rim components, by external
fire, or by excessive use of brakes.
A tire explosion is much more violent than a blowout.
The explosion can propel the tire, the rim
components, and the axle components from the
machine. Stay out of the trajectory path. Both the
force of the explosion and the flying debris can cause
property damage, personal injury, or death.
Illustration 47 g02643077
The recommended location for mounting the fire
extinguisher is inside on the left-hand access door
(1).
Make sure that a fire extinguisher is on the machine.
Make sure that you are familiar with the operation of
the fire extinguisher. Inspect the fire extinguisher and
service the fire extinguisher on a regular basis. Obey
the recommendations on the instruction plate.
If the fire extinguisher is mounted on the ROPS, strap
the mounting plate to a leg of the ROPS. If the weight
of the fire extinguisher is more than 4.5 kg (10 lb),
mount the fire extinguisher as low as possible on one
leg. Do not mount the fire extinguisher on the upper
one-third area of the leg.
Note: Do not weld the ROPS in order to install the fire
extinguisher. Also, do not drill holes in the ROPS in
order to mount the fire extinguisher on the ROPS.
Illustration 48 g02166933
Typical example of tire is shown
Do not approach a hot or an apparently damaged tire.
Prentice recommends against using water or
calcium as a ballast for the tires except in machines
designed for this additional mass. For those
applicable machines, the maintenance section will
contain instructions on the correct tire inflation and
filling procedures. Ballast, such as fluid in the tires,
increases overall machine weight and may affect
braking, steering, power train components, or the
certification of the protective structure such as the
ROPS. The use of tire/rim rust preventatives or other
liquid additives is not required.
Dry nitrogen gas is recommended for inflation of
tires. If the tires were originally inflated with air,
nitrogen is still preferred for adjusting the pressure.
Nitrogen mixes properly with air.
Nitrogen inflated tires reduce the potential of a tire
explosion because nitrogen does not aid combustion.
Nitrogen helps to prevent oxidation of the rubber,
deterioration of rubber, and corrosion of rim
components.
Page 28
28 SEBU8705
Safety Section
Electrical Storm Injury Prevention
To avoid overinflation, proper nitrogen inflation
equipment and training in the usage of the equipment
are necessary. A tire blowout or a rim failure can
result from improper equipment or from misused
equipment.
When you inflate a tire, stand behind the tread and
use a self-attaching chuck.
Servicing tires and rims can be dangerous. Only
trained personnel that use proper tools and proper
procedures should perform this maintenance. If
correct procedures are not used for servicing tires
and rims, the assemblies could burst with explosive
force. This explosive force can cause serious
personal injury or death. Carefully obey the specific
instructions from your tire dealer.

extended time period, remove the key in order to
avoid battery discharge that may be caused by a
battery short circuit, by the current draw via certain
components, or by vandalism.
Stay back until saw blade comes to complete stop
after shutdown. May cause serious injury or
death.
Slope Operation
SMCS Code: 7000; 7615
Machines that are operating safely in various
applications depend on these criteria: the machine
model, configuration, machine maintenance,
operating speed of the machine, conditions of the
terrain, fluid levels and tire inflation pressures. The
most important criteria are the skill and judgment of
the operator.
A trained operator that follows the instructions in the
Operation and Maintenance Manual has the greatest
impact on stability. Operator training provides a
person with the following abilities: observation of
working and environmental conditions, feel for the
machine, identification of potential hazards and
operating the machine safely by making appropriate
decisions.
When you work on side hills and when you work on
slopes, consider the following important points:
Note: Operation of this machine on slopes greater
than 30% (16.7 deg) is not recommended. A 30%
slope can be visualized by a .91 M (3 ft)rise in a 3 M
(10 ft) distance. Local slope conditions may dictate a
lower safe slope than 30% (16.7 deg).
Speed of travel – At higher speeds, forces of inertia
tend to make the machine less stable.
Illustration 50 g02728310
The SC57 is shown in this graphic. Other models are
similar.
8. Install the saw guard on the felling head.
Roughness of terrain or surface – The machine
may be less stable with uneven terrain.
Direction of travel – Avoid operating the machine
across the slope. When possible, operate the
machine up the slopes and operate the machine
down the slopes. Place the heaviest end of the
machine uphill when you are working on an incline.
Mounted equipment – Balance of the machine may
be impeded by the following components: equipment
that is mounted on the machine, machine
configuration, weights and counterweights.
Nature of surface – Ground that has been newly
filled with earth may collapse from the weight of the
machine.
Surface material – Rocks and moisture of the
surface material may drastically affect the machine
traction and stability. Rocky surfaces may promote
side slipping of the machine.
Slippage due to excessive loads – May cause
downhill tracks or downhill tires to dig into the ground,
which will increase the angle of the machine.
Width of tracks or tires – Narrower tracks or
narrower tires further increase the digging into the
ground which causes the machine to be less stable.
Implements attached to the drawbar – May
decrease the weight on the uphill tracks. May also
Page 33
SEBU8705 33
Safety Section
Equipment Lowering with Engine Stopped
decrease the weight on the uphill tires. The
decreased weight will cause the machine to be less
stable.
Height of the working load of the machine – When
the working loads are in higher positions, the stability
of the machine is reduced.
Operated equipment – Be aware of performance
features of the equipment in operation and the effects
on machine stability.
Operating techniques – Keep all attachments or
pulled loads low to the ground for optimum stability.
Machine systems have limitations on slopes –
Slopes can affect the proper function and operation of
the various machine systems. These machine
systems are needed for machine control.
Note: Safe operation on steep slopes may require
special machine maintenance. Excellent skill of the
operator and proper equipment for specific
applications are also required. Consult the Operation
and Maintenance Manual sections for the proper fluid
level requirements and intended machine use.

Equipment Lowering with
Engine Stopped
SMCS Code: 7000
Before lowering any equipment with the engine
stopped, clear the area around the equipment of all
personnel. The procedure to use will vary with the
type of equipment to be lowered. Keep in mind most
systems use a high pressure fluid or air to raise or
lower equipment. The procedure will cause high
pressure air, hydraulic, or some other media to be
released in order to lower the equipment. Wear
appropriate personal protective equipment and follow
the established procedure in the Operation and
Maintenance Manual, “Equipment Lowering with
Engine Stopped” in the Operation Section of the
manual.

SMCS Code: 7000
Any modifications to the inside of the operator station
should not project into the operator space or into the
space for the companion seat (if equipped). The
addition of a radio, fire extinguisher, and other
equipment must be installed so that the defined
operator space and the space for the companion seat
(if equipped) is maintained. Any item that is brought
into the cab should not project into the defined
operator space or the space for the companion seat
(if equipped). A lunch box or other loose items must
be secured. Objects must not pose an impact hazard
in rough terrain or in the event of a rollover.
i05265492
Guards
(Operator Protection)
SMCS Code: 6700; 7000; 7150; 7150-MCH; 7325
There are different types of guards that are used to
protect the operator. The machine and the machine
application determine the type of guard that should be
used.
A daily inspection of the guards is required in order to
check for structures that are bent, cracked, or loose.
Never operate a machine with a damaged structure.
The operator becomes exposed to a hazardous
situation if the machine is used improperly or if poor
operating techniques are used. This situation can
occur even though a machine is equipped with an
appropriate protective guard. Follow the established
operating procedures that are recommended for your
machine.
Roll over Protective Structure
(ROPS), Falling Object Protective
Structure (FOPS) or Tip Over
Protection Structure (TOPS)
Do not mount items (fire extinguishers, first aid kits,
work lights, etc.) by welding brackets to or by drilling
holes in the ROPS/FOPS Structure. Welding brackets
or drilling holes in the ROPS/FOPS Structures can
weaken the structures. Consult your Prentice dealer
for mounting guidelines.
The Tip Over Protection Structure (TOPS) is another
type of guard that is used on mini hydraulic
excavators. This structure protects the operator in the
event of a tipover. The same guidelines for the
inspection, the maintenance, and the modification of
the ROPS/FOPS Structure are required for the Tip
Over Protection Structure.
Other Guards (If Equipped)
Protection from flying objects and/or falling objects is
required for special applications. Logging applications
and demolition applications are two examples that
require special protection.
A front guard is required when a work tool that
creates flying objects is used. Front guards that are
approved by Prentice or polycarbonate front guards
that are approved by Prentice are available for
machines with a cab or an open canopy. On
machines that are equipped with cabs, the windows
should also be closed. Safety glasses are
recommended when flying hazards exist for
machines with cabs and machines with open
canopies.
If the work material extends above the cab, top
guards and front guards should be used. Typical
examples of this type of application are listed below:
• Demolition applications
• Rock quarries
• Forestry products
Additional guards may be required for specific
applications or work tools. The Operation and
Maintenance Manual for your machine or your work
tool will provide specific requirements for the guards.
Consult your Prentice dealer for additional
information.
The ROPS/FOPS Structure (if equipped) on your
machine is designed, tested, and certified for that
machine. Any alteration or any modification to the
ROPS/FOPS Structure could weaken the structure.
Placing the operator into an unprotected
environment. Modifications or attachments that cause
the machine to exceed the weight stamped on the
certification plate also place the operator into an
unprotected environment. Excessive weight may
inhibit the brake performance, the steering
performance, and the ROPS. The protection that is
offered by the ROPS/FOPS Structure will be impaired
if the ROPS/FOPS Structure has structural damage.
Damage to the structure can be caused by an
overturn, a falling object, a collision, etc.

Diesel Particulate Filter
Regeneration
SMCS Code: 108F
Regeneration
Regeneration is the removal of soot from the Diesel
Particulate Filter (DPF). The Aftertreatment
Regeneration Device (ARD) is used to regenerate the
DPF. The DPF traps both soot and ash. The ash is
removed through a manual cleaning process. Refer
to Operation and Maintenance Manual, “Diesel
Particulate Filter - Clean” for more information on the
service of the DPF.
Regeneration Indicators
High Exhaust System Temperature –
This indicator will illuminate in order to
show that the ARD is active. This
indicator will turn off when regeneration is
complete.
DPF – This indicator will illuminate in
order to show that a regeneration is
needed. This indicator will illuminate
when the soot level reaches 90%.
Note: If the engine start switch key is cycled while the
regeneration system is disabled via the disable
regeneration switch, press and hold the disable
regeneration switch for 2 seconds to re-initiate the
disable regeneration.
Soot Level Monitoring
Illustration 98 g02228033
The soot level monitor indicates the level of soot that
has accumulated within the DPF. The five marks on
the monitor represent a percentage of soot within the
DPF. The first mark indicates 0% soot level. The
second mark indicates 25% soot level. The middle
mark indicates 50% soot level. The fourth mark
indicates 75% soot level. The last mark indicates
100% soot level. The soot level monitor can be used
to optimize DPF regenerations based upon the work
cycle of your machine. If machine conditions do not
allow for an automatic regeneration, a forced
regeneration should be performed before the soot
level gauge indicates 100%.
Regeneration Disabled – This indicator
will illuminate in order to show that a
regeneration has been disabled.
Delayed Engine Shutdown (If Equipped)
– This indicator illuminates in order to
show that the delayed engine shutdown
is active.
Regeneration Switch
Note: The MIDDLE position of the regeneration
switch is the default position for automatic
regeneration.
Force Regeneration – Press in the top of
the switch for 2 seconds in order to
begin regeneration.
Disable Regeneration – Press in the
bottom of the switch for 2 seconds in
order to disable regeneration.
Note: To re-enable the regeneration, cycle the engine
start switch key or press and hold down the force
regeneration switch for 2 seconds. If the soot level is
above 15%, an active regeneration will begin if you
are within the low speed automatic regeneration
window.
Note: Some machines will display soot level as a
percentage and will not use a graphical depiction as
displayed above.
Modes of Regeneration
• Automatic: An automatic regeneration is allowed
between approximately 30% and 100% on the
soot level monitor. There are two types of
automatic regeneration, low speed automatic and
high speed automatic.
• Forced: A forced regeneration is initiated by
pressing the force regeneration switch. A forced
regeneration is allowed when the soot level is
equal to or greater than 15%. The machine must
be brought to a low idle speed in order to perform a
forced regeneration.
• Disabled: When the regeneration system is in
disabled mode, automatic regenerations will not be
performed.

Machine Operation
Diesel Particulate Filter Regeneration
High speed automatic regenerations are ideal for
situations where interruptions in the work cycle are
not acceptable. In situations where the engine is not
allowed to idle, regenerations will automatically take
place during the normal work cycle of the machine if
the above criteria are met. High speed regenerations
take longer to complete and the aftertreatment
regeneration device consumes more fuel when high
speed regenerations are utilized.
Note: If high speed regenerations are not being
performed, take the engine to low speed regeneration
window before investigating system for issues. There
are other factors not outlined above which need to be
met in order for high speed automatic regenerations
to occur.

the engine must be at a state of low idle, refer to
illustration 99 . Machine should be stationary .
Engaging the parking brake or hydraulic lock will
ensure the quickest start time for regeneration. If low
idle speed is less than 1000 rpm, engine speed will
automatically increase to between 1000 and 1400
rpm to activate regeneration.
Load on engine should be minimal. Soot percentage
must be between 30% and 100% on the soot monitor.
Low speed automatic regenerations are ideal in
environments where interruptions in the work cycle of
the machine are not a problem. By utilizing low speed
regenerations, the duration of the regeneration will be
shortest and less fuel will be consumed by the
aftertreatment regeneration device when low speed
regenerations are used.
Engine load factor can be anywhere between 15%
and 100%
Soot load percentage will be between 75 and 90%
when this type of regeneration is available.
High speed automatic regenerations are ideal for
situations where interruptions in the work cycle are
not acceptable. In situations where the engine is not
allowed to idle, regenerations will automatically take
place during the normal work cycle of the machine if
the above criteria are met. High speed regenerations
take longer to complete and the aftertreatment
regeneration device consumes more fuel when high
speed regenerations are utilized.
Note: If high speed automatic regenerations are not
being performed, take the engine to low speed
regeneration window before investigating system for
issues. There are other factors not outlined above
which need to be met in order for high speed
automatic regenerations to occur.

Machine Operation
Diesel Particulate Filter Regeneration
Regeneration should be performed as soon as
possible. If high speed automatic regenerations
are not activating, take engine to low speed
automatic window or perform a forced
regeneration.
Indicator will turn off once DPF regeneration has
started.
Note: In some situations, the DPF indicator may stay
illuminated when the soot load is below 90%. The
illuminated DPF indicator indicates that a complete
regeneration has not been performed. A complete
regeneration is when the soot level is reduced to 0%.
If the DPF indicator stays illuminated, perform a
regeneration without interruption until the soot level is
reduced to 0%. A complete regeneration will reset the
DPF indicator.
Illustration 101 g02117259
Finally, if engine is still allowed to run through multiple
forced shutdowns, the DPF must be replaced.
Key Off Regeneration (If Equipped)
Note: There may be some local regulations and/or
government regulations that define the requirements
for the operator and/or support personnel to be
present when the engine is running. Obey these
regulations.
Use of the Key Off Regeneration feature or the Delayed Engine Shutdown feature allows the engine
to run for a period with the engine start switch key
removed. Leaving the machine unattended when
the engine is running could result in personal injury or property damage. When using the Key Off
Regeneration feature or the Delayed Engine Shutdown feature, do not leave the machine unattended when the engine is running. Once the
engine has stopped, perform a visual check of the
machine to ensure that the machine is in a safe
state before leaving the machine unattended.
The DPF indicator will illuminate and an action lamp
will illuminate when the engine control module
determines the amount of soot collected in the DPF
has reached a level that a regeneration is required.
The machine should be brought to the NEUTRAL
position immediately. Both forced regeneration and
low speed automatic regeneration are possible.
Engine power will be slightly derated if the machine
continues to operate.
Illustration 102 g02117261
After a certain period, an action alarm will activate.
After 5 minutes with the action alarm active, the
engine will automatically be taken to low idle.
A forced regeneration is required at this time. A
complete regeneration will unlock the forced low idle
speed. Cycling the engine start switch key will unlock
the forced low idle speed.
After a certain amount of time, engine will
automatically shut down. Engine can be restarted but
will only run for 30 seconds before shutting down
again. Once engine enters shutdown strategy,
regeneration is locked out and a Prentice dealer must
be called to perform a service level regeneration.
Note: Safe state (lowering work tools to the ground,
applying brakes, etc.) shall be attained before the
engine start switch is moved to the OFF position.
Confirmation of a safe state should be conducted
after the engine is stopped.
Key off regeneration allows for regeneration when the
engine start switch key has been removed. To begin a
key off regeneration the soot level must be between
15% and 100% on the soot level monitor and/or a
regeneration is in progress. The following steps
outline the procedure of a key off regeneration:
1. Remove the engine start switch key.
2. The engine will continue to run for 15 seconds.
During this 15 second interval, if a regeneration is
desired, press and hold the force regeneration
switch for 2 seconds.
Note: If a regeneration is not desired the machine will
initiate the delayed engine shutdown.
3. The key off regeneration will activate and the key
off regeneration will last for up to 15 minutes.
4. Once the key off regeneration is complete the
machine will initiate the delayed engine shutdown.
5. The delayed engine shutdown can last up to 10
minutes.
6. After the delayed engine shutdown has been
completed the engine will shut down.

i05265371
Towing the Machine
SMCS Code: 7000
Personal injury or death could result when towing
a disabled machine incorrectly.
Block the machine to prevent movement before
releasing the brakes. The machine can roll free if
it is not blocked.
To properly perform the towing procedure, use the
following recommendations.
Use these towing instructions for moving a disabled
machine over a short distance of 8 km (5 MI.) or less.
Do not move the machine faster than 3 km/h (2 mph).
Move the machine to a convenient location for repair.
Always haul the machine if long distance moving is
required.
Shielding must be provided on the towing machine in
order to protect the operator in case the tow line or
the tow bar breaks.
It may be necessary to connect a larger machine or
additional machines to the disabled machine in order
to provide sufficient control and sufficient braking.
This will prevent the disabled machine from rolling
away out of control on a downgrade.
The requirements for all different situations cannot be
specified. Minimal towing machine capacity is
required on smooth, level surfaces. Maximum towing
machine capacity is required on inclines or on poor
surface conditions.
Any towed machine with a load must be equipped
with a braking system that can be operated from the
operator compartment.
Consult your Prentice dealer for more information
about towing a disabled machine.
Towing with a Running Engine
If the engine is running, the machine can be towed for
a short distance under certain conditions. The power
train and the steering system must be operable. Tow
the machine for a short distance only. For
example, pull the machine out of mud or to the side of
the road.
The operator on the towed machine must steer the
machine in the direction of the tow line.
Carefully obey all of the instructions that are outlined
in this topic.
Do not allow riders on a machine that is being towed
unless the operator can control the steering and/or
the braking of the towed machine.
Before you tow the machine, inspect the tow line or
the tow bar. Make sure that the tow line or the tow bar
is sturdy enough for towing the disabled machine.
The tow line or tow bar must have a strength that is
equal to 1.5 times the gross weight of the machine
that is being towed.
Do not use a chain for pulling. A chain link may break
and can cause personal injury. Use a wire rope that
has cable loops or end rings. Position an observer at
a safe location. The observer should stop the pulling
procedure if the cable starts to break or the cable
starts to unravel. If the towing machine moves without
the pulled machine, stop the pulling procedure.
Keep the tow line angle to a minimum. Do not exceed
a 30 degree angle from the straight ahead position.
Quick machine movement could overload the tow line
or the tow bar, causing the tow line or the tow bar to
break. Gradual, smooth machine movement works
better.
Normally, the towing machine should be as large as
the disabled machine. The towing machine must
have enough brake capacity, enough weight, and
enough power for the grade and distance that is
involved.

Tire Inflation with Nitrogen
Maintenance Section
Tire Inflation Information
i01676064
Tire Inflation with Nitrogen
SMCS Code: 4203
Dry nitrogen gas can be used for tire inflation and for
tire pressure adjustments. This includes all machines
with rubber tires. Nitrogen is an inert gas that will not
aid combustion inside the tire.
Proper nitrogen inflation equipment, and training
in using the equipment, are necessary to avoid
over inflation. A tire blowout or rim failure can result from improper or misused equipment and
personal injury or death can occur.
A tire blowout and/or rim failure can occur if the
inflation equipment is not used correctly, due to
the fact that a fully charged nitrogen cylinder's
pressure is approximately 15000 kPa (2200 psi).
There are other benefits to using nitrogen in addition
to reducing the risk of an explosion. The use of
nitrogen for tire inflation lessens the slow oxidation of
the rubber. Use of nitrogen also slows gradual tire
deterioration. This is especially important for tires that
are expected to have a long service life of at least
four years. Nitrogen reduces the corrosion of rim
components. Nitrogen also reduces problems that
result from disassembly.
A tire blowout or a rim failure can cause personal
injury.
Use a self-attaching inflation chuck and stand behind the tread when inflating a tire, to prevent personal injury.
Note: Do not set the tire inflation equipment regulator
higher than 140 kPa (20 psi) over the recommended
tire pressure.
Use 6V-4040 Inflation Group or an equivalent
inflation group to inflate tires with a nitrogen gas
cylinder. Refer to Special Instruction, SMHS7867 for
tire inflation instructions.

Tire Inflation Pressure
Adjustment
SMCS Code: 4203
Always obtain the proper tire inflation pressures and
maintenance recommendations for the tires on your
machine from your tire supplier. The tire pressure in a
warm shop area 18° to 21°C (65° to 70°F) will
significantly change when you move the machine into
freezing temperatures. If you inflate the tire to the
correct pressure in a warm shop, the tire will be
underinflated in freezing temperatures. Low pressure
shortens the life of a tire.
Reference: When you operate the machine in
freezing temperatures, refer to Special Publication,
SEBU5898, “Cold Weather Recommendations for All
Prentice Machines” in order to adjust tire inflation
pressures.

General Information for Lubricants
When you are operating the machine in temperatures
below −20°C (−4°F), refer to Special Publication,
SEBU5898, “Cold Weather Recommendations”. This
publication is available from your Prentice dealer.
Refer to the “Lubricant Information” section in the
latest revision of the Special Publication, SEBU6250,
“Caterpillar Machine Fluids Recommendations” for a
list of Cat engine oils and for detailed information.
This manual may be found on the Web at Safety.Cat.
com.
The footnotes are a key part of the tables. Read ALL
footnotes that pertain to the machine compartment in
question.
Selecting the Viscosity
In order to select the proper oil for each machine
compartment, refer to the “Lubricant Viscosity for
Ambient Temperature” table. Use the oil type AND oil
viscosity for the specific compartment at the proper
ambient temperature.
Page 80
80 SEBU8705
Lubricant Viscosities and Refill Capacities
Lubricant Viscosities
The proper oil viscosity grade is determined by the
minimum ambient temperature (the air in the
immediate vicinity of the machine). Measure the
temperature when the machine is started and while
the machine is operated. In order to determine the
proper oil viscosity grade, refer to the “Min” column in
the table. This information reflects the coldest
ambient temperature condition for starting a cold
machine and for operating a cold machine. Refer to
the “Max” column in the table for operating the
machine at the highest temperature that is
anticipated. Unless specified otherwise in the
“Lubricant Viscosities for Ambient Temperatures”
tables, use the highest oil viscosity that is allowed for
the ambient temperature.
Machines that are operated continuously should use
oils that have the higher oil viscosity in the final drives
and in the differentials. The oils that have the higher
oil viscosity will maintain the highest possible oil film
thickness. Refer to “General Information for
Lubricants” article, “Lubricant Viscosities” tables, and
any associated footnotes. Consult your Prentice
dealer if additional information is needed.
NOTICE
Not following the recommendations found in this manual can lead to reduced performance and compartment failure.
• Diesel Particulate Filters (DPF)
• Diesel Oxidation Catalysts (DOC)
• Selective Catalytic Reduction (SCR)
• Lean NOx Traps (LNT)
Other systems may apply.
Engine Oil
Cat oils have been developed and tested in order to
provide the full performance and life that has been
designed and built into Cat engines.
Cat DEO-ULS or oils that meet the Cat ECF-3
specification and the API CJ-4 are required for use in
the applications listed below. Cat DEO-ULS and oils
meeting Cat ECF-3 specification and the API CJ-4
and ACEA E9 oil categories have been developed
with limited sulfated ash, phosphorus, and sulfur.
These chemical limits are designed to maintain the
expected aftertreatment devices life, performance,
and service interval. If oils meeting the Cat ECF-3
specification and the API CJ-4 specifications are not
available, oils meeting ACEA E9 may be used. ACEA
E9 oils meet the chemical limits designed to maintain
aftertreatment device life. ACEA E9 oils are validated
using some but not all ECF-3 and API CJ-4 standard
engine performance tests. Consult your oil supplier
when considering use of an oil that is not Cat ECF-3
or API CJ-4 qualified.
Failure to meet the listed requirements will damage
aftertreatment-equipped engines and can negatively
impact the performance of the aftertreatment devices.
The Diesel Particulate Filter (DPF) will plug sooner
and require more frequent DPF ash service intervals.
Typical aftertreatment systems include the following:

Diesel Fuel Recommendations
Illustration 124 g02157153
NACD Film
• Shorten the time interval between
aftertreatment device service intervals (cause
the need for more frequent service intervals)
• Adversely impact the performance and life of
aftertreatment devices (cause loss of
performance)
• Reduce regeneration intervals of
aftertreatment devices
• Reduce engine efficiency and durability.
• Increase the wear.
• Increase the corrosion.
• Increase the deposits.
• Lower fuel economy
• Shorten the time period between oil drain intervals
(more frequent oil drain intervals).
• Increase overall operating costs.
Failures that result from the use of improper fuels are
not Prentice factory defects. Therefore the cost of
repairs would not be covered by a Prentice warranty.
Illustration 125 g02052934
EAME Film
Diesel fuel must meet “Caterpillar Specification for
Distillate Fuel” and the latest versions of “ASTM
D975” or “EN 590” in order to ensure optimum
engine performance. Refer to Special Publication,
SEBU6250, “Caterpillar Machine Fluids
Recommendations” for the latest fuel information and
for Cat fuel specification. This manual may be found
on the Web at Safety.Cat.com.
NOTICE
Ultra Low Sulfur Diesel (ULSD) fuel 0.0015 percent
(≤15 ppm (mg/kg)) sulfur is required by regulation for
use in engines certified to nonroad Tier 4 standards
(U.S. EPA Tier 4 certified) and that are equipped with
exhaust aftertreatment systems.
European ULSD 0.0010 percent (≤10ppm (mg/kg))
sulfur fuel is required by regulation for use in engines
certified to European nonroad Stage IIIB and newer
standards and are equipped with exhaust aftertreat-
ment systems.
Misfueling with fuels of higher sulfur level can
have the following negative effects:
Prentice does not require the use of ULSD in off road
and machine applications that are not Tier 4/Stage
IIIB certified engines. ULSD is not required in engines
that are not equipped with after treatment devices.
For Tier 4/Stage IIIB/Stage IV certified engines
always follow operating instructions. Fuel tank inlet
labels are installed in order to ensure that the correct
fuels are used.
Refer to Special Publication, SEBU6250, “Caterpillar
Machine Fluids Recommendations” for more details
about fuels, lubricants, and Tier 4 requirements. This
manual may be found on the Web at Safety.Cat.com.
Fuel Additives
Cat Diesel Fuel Conditioner and Cat Fuel System
Cleaner are available for use when needed. These
products are applicable to diesel and biodiesel fuels.
Consult your Prentice dealer for availability.
Biodiesel
Biodiesel is a fuel that can be made from various
renewable resources that include vegetable oils,
animal fat, and waste cooking oil. Soybean oil and
rapeseed oil are the primary vegetable oil sources. In
order to use any of these oils or fats as fuel, the oils or
fats are chemically processed (esterified). The water
and contaminants are removed.
U.S. distillate diesel fuel specification “ASTM D97509a” includes up to B5 (5 percent) biodiesel.
Currently, any diesel fuel in the U.S. may contain up
to B5 biodiesel fuel.
Page 85
SEBU8705 85
Lubricant Viscosities and Refill Capacities
Capacities (Refill)
European distillate diesel fuel specification “EN 590”
includes up to B5 (5 percent) and in some regions up
to B7 (7 percent) biodiesel. Any diesel fuel in Europe
may contain up to B5 or in some regions up to B7
biodiesel fuel.
Note: The diesel portion used in the biodiesel blend
must be Ultra Low Sulfur Diesel (15 ppm sulfur or
less, per “ASTM D975”). In Europe the diesel fuel
portion used in the biodiesel blend must be sulfur free
diesel (10 ppm sulfur or less, per “EN 590”). The final
blend must have 15 ppm sulfur or less.
Note: Up to B20 biodiesel blend level is acceptable
for use in Excavator engines.
When biodiesel fuel is used, certain guidelines must
be followed. Biodiesel fuel can influence the engine
oil, aftertreatment devices, non-metallic, fuel system
components, and others. Biodiesel fuel has limited
storage life and has limited oxidation stability. Follow
the guidelines and requirements for engines that are
seasonally operated and for standby power
generation engines.
In order to reduce the risks associated with the use of
biodiesel, the final biodiesel blend and the biodiesel
fuel used must meet specific blending requirements.
All the guidelines and requirements are provided in
the latest revision of Special Publication, SEBU6250,
“Caterpillar Machine Fluids Recommendations”. This
manual may be found on the Web at Safety.Cat.com.

SMCS Code: 1000; 7000
Do not weld on any protective structure. If it is
necessary to repair a protective structure, contact
your Prentice dealer.
Proper welding procedures are necessary in order to
avoid damage to the electronic controls and to the
bearings. When possible, remove the component that
must be welded from the machine or the engine and
then weld the component. If you must weld near an
electronic control on the machine or the engine,
temporarily remove the electronic control in order to
prevent heat-related damage. The following steps
should be followed in order to weld on a machine or
an engine with electronic controls.
1. Turn off the engine. Place the engine start switch in
the OFF position.
• IQAN Module - Located in the cab
• XA2 Module - Located in the front frame
• Product Link Module - Located in the cab
5. Protect any wiring harnesses and components
from the debris and the spatter which is created
from welding.
6. Use standard welding procedures in order to weld
the materials together.
2. Turn the battery disconnect switch to the OFF
position. If there is no battery disconnect switch,
remove the negative battery cable at the battery.
NOTICE
Do NOT use electrical components (ECM or sensors)
or electronic component grounding points for grounding the welder.
3. Clamp the ground cable from the welder to the
component that will be welded. Place the clamp as
close as possible to the weld. Make sure that the
electrical path from the ground cable to the
component does not go through any bearing. Use
this procedure in order to reduce the possibility of
damage to the following components:
• Bearings of the drive train
• Hydraulic components
• Electrical components (Engine ECM, IQAN
Module, XA2 Module and the Product Link
Module.
• Other components of the machine
