Safety

The safety section lists basic safety precautions. In
addition, this section identifies the text and locations

of warning signs and labels used on the machine.

Read and understand the basic precautions listed in
the safety section before operating or performing
lubrication, maintenance and repair on this machine.

Operation

The operation section is a reference for the new
operator and a refresher for the experienced operator.
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.

Battery posts, terminals and related accessories

Safety Section

General Hazard Information

When maintenance is performed above ground level,
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 36 g00702020

Wear a hard hat, protective glasses, and other
protective equipment, as required.

Do not wear loose clothing or jewelry that can snag
on controls or on other parts of the equipment.

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,
and other items that are not a part of the equipment.

Know the appropriate work site hand signals and the
personnel that are authorized to give the hand
signals. Accept hand signals from one person only.

Do not smoke when you service an air conditioner.
Also, do not smoke if refrigerant gas may be present.
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.

General Hazard Information

Inhalation

Illustration 37 g00687600

Always use a board or cardboard when you check for
a leak. Leaking fluid that is under pressure can
penetrate body tissue. Fluid penetration 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.

Containing Fluid Spillage

Care must be taken in order to ensure that fluids are
contained during performance of inspection,

maintenance, testing, adjusting, and repair of the
equipment. Prepare to collect the fluid with suitable
containers before opening any compartment or
disassembling any component containing fluids.

Refer to Special Publication, NENG2500, “Tools and
Shop Products Guide” for the following items:

• Tools that are suitable for collecting fluids and

equipment that is suitable for collecting fluids

• Tools that are suitable for containing fluids and

Exhaust

Use caution. Exhaust fumes can be hazardous to
your health. If you operate the machine in an

enclosed area, adequate ventilation is necessary.

Asbestos Information

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:

SEBU9024 21

SMCS Code: 7000

Support the equipment properly before you perform
any work or maintenance beneath that equipment. Do
not depend on the hydraulic cylinders to hold up the
equipment. Equipment can fall if a control is moved,
or if a hydraulic line breaks.

Do not work beneath the cab of the machine unless
the cab is properly supported.

Unless you are instructed otherwise, never attempt
adjustments while the machine is moving or while the
engine is running.

Never jump across the starter solenoid terminals in
order to start the engine. Unexpected machine
movement could result.

Whenever there are equipment control linkages the
clearance in the linkage area will change with the
movement of the equipment or the machine. Stay
clear of areas that may have a sudden change in
clearance with machine movement or equipment

movement.

Stay clear of all rotating and moving parts.

If it is necessary to remove guards in order to perform
maintenance, always install the guards after the
maintenance is performed.

Improperly disposing of waste can threaten the
environment. Potentially harmful fluids should be
disposed of according to local regulations.

Always use leakproof containers when you drain
fluids. Do not pour waste onto the ground, down a
drain, or into any source of water.

Keep objects away from moving fan blades. The fan
blade will throw objects or cut objects.

Do not use a kinked wire cable or a frayed wire cable.
Wear gloves when you handle wire cable.

When you strike a retainer pin with force, the retainer
pin can fly out. The loose retainer pin can injure
personnel. Make sure that the area is clear of people
when you strike a retainer pin. To avoid injury to your
eyes, wear protective glasses when you strike a
retainer pin.

Chips or other debris can fly off an object when you
strike the object. Make sure that no one can be
injured by flying debris before striking any object.

Safety Section
Fire Prevention and Explosion Prevention

Coolant

When the engine is at operating temperature, the
engine coolant is hot. The coolant is also under
pressure. The radiator and all lines to the heaters or
to the engine contain hot coolant.

Any contact with hot coolant or with steam can cause
severe burns. Allow cooling system components to
cool before the cooling system is drained.

Check the coolant level only after the engine has
been stopped.

Ensure that the filler cap is cool before removing the
filler cap. The filler cap must be cool enough to touch
with a bare hand. Remove the filler cap slowly in
order to relieve pressure.

Cooling system conditioner contains alkali. Alkali can
cause personal injury. Do not allow alkali to contact
the skin, the eyes, or the mouth.

Oils

Hot oil and hot components can cause personal
injury. Do not allow hot oil to contact the skin. Also, do
not allow hot components to contact the skin.

Remove the hydraulic tank filler cap only after the
engine has been stopped. The filler cap must be cool
enough to touch with a bare hand. Follow the
standard procedure in this manual in order to remove
the hydraulic tank filler cap.

Batteries

The liquid in a battery is an electrolyte. Electrolyte is
an acid that can cause personal injury. Do not allow
electrolyte to contact the skin or the eyes.

Do not smoke while checking the battery electrolyte
levels. Batteries give off flammable fumes which can
explode.

SMCS Code: 7000

Illustration 40 g00704000

General

All fuels, most lubricants, and some coolant mixtures
are flammable.

To minimize the risk of fire or explosion, Prentice
recommends the following actions.

Always perform a Walk-Around Inspection, which
may help you identify a fire hazard. Do not operate a
machine when a fire hazard exists. Contact your
Prentice dealer for service.

Understand the use of the primary exit and alternative
exit on the machine. Refer to Operation and
Maintenance Manual, “Alternative Exit”.

Do not operate a machine with a fluid leak. Repair
leaks and clean up fluids before resuming machine
operation. Fluids that are leaking or spilled onto hot
surfaces or onto electrical components can cause a
fire. A fire may cause personal injury or death.

Remove flammable material such as leaves, twigs,
papers, trash, and so on. These items may
accumulate in the engine compartment or around
other hot areas and hot parts on the machine.

Keep the access doors to major machine
compartments closed and access doors in working
condition in order to permit the use of fire suppression
equipment, in case a fire should occur.

Clean all accumulations of flammable materials such
as fuel, oil, and debris from the machine.

Do not operate the machine near any flame.

SEBU9024 23

Safety Section

Fire Prevention and Explosion Prevention

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
torque. Damage to the protective cover or insulation
may provide fuel for fires.

Store fuels and lubricants in properly marked
containers away from unauthorized personnel. Store
oily rags and flammable materials in protective
containers. Do not smoke in areas that are used for

storing flammable materials.

Avoid static electricity risk when fueling. Ultra low
sulfur diesel (ULSD) poses a greater static ignition
hazard than earlier diesel formulations with a higher
sulfur content. Avoid death or serious injury from fire
or explosion. Consult with your fuel or fuel system
supplier to ensure that the delivery system is in
compliance with fueling standards for proper
grounding and bonding practices.

Never store flammable fluids in the operator
compartment of the machine.

Battery and Battery Cables

Illustration 41 g00704059

Use caution when you are fueling a machine. Do not
smoke while you are fueling a machine. Do not fuel a
machine near open flames or sparks. Always stop the
engine before fueling. Fill the fuel tank outdoors.

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

• 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. This
may result in an unsafe condition for servicing the
machine. Repair components or replace components
before servicing 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. This will help to prevent
vibration, rubbing against other parts, and excessive
heat during machine operation.

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.

Lines, Tubes, and Hoses

Do not bend high-pressure lines. Do not strike high­pressure lines. Do not install any lines that are bent or
damaged. Use the appropriate backup wrenches in
order to tighten all connections to the recommended
torque.

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.

Illustration 43 g00687600

Check lines, tubes, and hoses carefully. Wear
Personal Protection Equipment (PPE) in order to
check for leaks. Always use a board or cardboard
when you check for a leak. Leaking fluid that is under
pressure can penetrate body tissue. Fluid penetration
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:

secondary exits before you operate the machine.

Note: Locate fire extinguishers and how to use a fire
extinguisher before you operate the machine.

If you find that you are involved in a machine fire, your
safety and that of others on site is the top priority. The
following actions should only be performed if the
actions do not present a danger or risk to you and any
nearby people. At all times you should assess the risk
of personal injury and move away to a safe distance
as soon as you feel unsafe.

Move the machine away from nearby combustible
material such as fuel/oil stations, structures, trash,

mulch and timber.

Lower any implements and turn off the engine as
soon as possible. If you leave the engine running, the
engine will continue to feed a fire. The fire will be fed
from any damaged hoses that are attached to the
engine or pumps.

If possible, turn the battery disconnect switch to the
OFF position. Disconnecting the battery will remove
the ignition source in the event of an electrical short.
Disconnecting the battery will eliminate a second
ignition source if electrical wiring is damaged by the
fire, resulting in a short circuit.

Use ether in well ventilated areas. Do not smoke
while you are replacing an ether cylinder or while you

are using an ether spray.

Do not store ether cylinders in living areas or in the
operator compartment of a machine. Do not store
ether cylinders in direct sunlight or in temperatures
above 49° C (120.2° F). Keep ether cylinders away
from open flames or sparks.

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.

Be familiar with the operation of the fire extinguisher.
Inspect the fire extinguisher and service the fire
extinguisher regularly. Follow the recommendations
on the instruction plate.

Notify emergency personnel of the fire and your
location.

If your machine is equipped with a fire suppression
system, follow the manufacturers procedure for
activating the system.

Note: Fire suppression systems need to be regularly
inspected by qualified personnel. You must be trained
to operate the fire suppression system.

Use the on-board fire extinguisher and use the
following procedure:

1. Pull the pin.

2. Aim the extinguisher or nozzle at the base of the

fire.

3. Squeeze the handle and release the extinguishing
agent.

4. Sweep the extinguisher from side to side across
the base of the fire until the fire is out.

If the fire grows out of control, be aware of the
following risks:

• Tires on wheeled machines pose a risk of
explosion as tires burn. Hot shrapnel and debris
can be thrown great distances in an explosion.

• Tanks, accumulators, hoses, and fittings can
rupture in a fire, spraying fuels and shrapnel over a
large area.

• Remember that nearly all of the fluids on the
machine are flammable, including coolant and oils.
Additionally, plastics, rubbers, fabrics, and resins
in fiberglass panels are also flammable.

Safety Section

Tire Information

i05780053

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.

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.

i01122596

Electrical Storm Injury
Prevention

SMCS Code: 7000

When lightning is striking in the vicinity of the
machine, the operator should never attempt the
following procedures:

Illustration 45 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.

• Mount the machine.

• Dismount the machine.

If you are in the operator's station during an electrical
storm, stay in the operator's station. If you are on the
ground during an electrical storm, stay away from the
vicinity of the machine.

Dangerous Operation Practices

Do not use feller bunchers to harvest trees in a
fallen or blown over condition. Serious personal
injury or death may result from high velocity
projectiles being thrown through the cab window.

Feller bunchers are intended to fell standing trees,
not for harvesting fallen or blown over trees.

Do not use feller buncher to cut when the head and
saw disc are tilted forward from the cab more than 20
degrees. Such use may result in high velocity

projectiles, like wood pieces, being thrown with
enough force to penetrate cab window. Projectiles
penetrating the cab windows or entering the cab can
cause serious personal injury or death.

The polycarbonate windows are designed to standard
specification that offer protection under most
conditions of normal operation.

Feller bunchers are not designed to harvest fallen
or blown over trees. doing so can cause serious
personal injury or death.

30 SEBU9024

Work Tools

• Never intentionally let the disc hit a rock

• ONLY fell with the disc horizontal and the bunching

head vertical. DO NOT cut with the feller buncher
tipped forward.

Operation in Rocky Terrain

Flying debris, falling trees, limbs, and tops can
cause severe injury or death. Do not operate saw
within 91 M (300 feet) of personnel or machinery.

Operating feller buncher in rocky conditions is
hazardous and should be avoided. If felling in rocky
conditions cannot be avoided the following
precautions should be taken:

• Use only solid steel teeth. DO NOT use carbide

tipped teeth.

• Make the cut high enough to clear the rocks.

NOTICE
Teeth breaking when hitting a rock can damage the
tooth seat on the saw disc. The more economical op­tion is to use a segmented disc. When broken tooth
damages the tooth seat, replace tooth and the seg­ment instead of a whole disc.

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%.

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: 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 104 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%.

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.

Low Speed Automatic Regeneration (1)

the engine must be at a state of low idle, refer to
illustration 105 . 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.

High Speed Automatic Regeneration (2)

Engine can be operating between approximately
1400 rpm and 2200 rpm

Engine load factor can be anywhere between 30%
and 85%

Soot load percentage will be between 60 and 75%
when this type of regeneration is available.

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.

High Speed Automatic Regeneration (3)

Engine can be operating between approximately
1000 rpm and 2200 rpm

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.

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 107 g02117259

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.

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.

Cab Tilting

SMCS Code: 7301-084; 7341-084; 7341

Do not tilt the cab when occupied. Before tilting
the cab remove all loose articles from the cab, se­cure all windows and emergency exits, and then
close the cab and cab riser doors. Failure to do so
can result in personal injury or damage to the
machine.

Downhill Operation

Maintain a ground speed that is slow enough for the
conditions. Before you operate down a hill, select the
proper range before you start down the grade. The
range should allow the machine to maintain the
appropriate speed on the down grade. The throttle
control should be at high idle and the engine should
not overspeed. In most situations, the range will be
the same range that is required to drive up the grade.

If the machine builds up excessive speed, the engine
can overspeed. Use the service brake in order to slow
the machine until a lower range can be selected.
Select the lower range and proceed with the throttle
control at high idle.

Use the service brakes for stopping the machine.
Using the service brakes in order to control travel
speed of the machine or using the service brakes for
stopping from high speeds can cause the brake axle
oil to overheat. This can result in significant wear and/
or damage to the service brakes.

Do not use the reverse travel pedal in order to slow
the machine when you travel forward downhill. Do not
use the forward travel pedal in order to slow the
machine when you travel reverse downhill.

Engine Idle Management System

The Engine Idle Management System (EIMS) is
designed to help maximize fuel efficiency. EIMS
allows flexibility to manage idle speeds. The EIMS
engine software comes with two idle control settings:
hibernate mode and work mode.

Before the first Work Mode after machine starting, the
machine will set the idle speed so a transmission oil
level check can be completed. The idle speed will be
held for 5 minutes with the low idle set to 800 rpm.
The following conditions must be met:

88 SEBU9024

Engine Starting
Engine Starting

• The throttle is released

• The parking brake is engaged

• The transmission is in neutral

• The implements are not active

• There are no active diagnostic codes

If any of the above conditions are not met, the
transmission oil level check will not occur again until
the next power cycle.

Note: If there is an active diagnostic code on the
machine, the machine may operate at the
programmed idle speed.

Hibernate Mode

If your machine has higher idle time, hibernate mode
will provide lower fuel consumption, reduced sound
level, and reduced emissions levels. Fuel

consumption savings will vary by the model of the
machine and work cycle. The hibernate mode is
engaged after 10 seconds and the following
conditions are met:

• The parking brake is engaged

• The implements are not active

• There are no active diagnostic codes

• The coolant temperature is greater than 50C

• The DPF outlet temperature is less than 200C

Work Mode

The work mode is the low idle speed of the machine
during normal operation. The engine idle speed for
work mode may be set in order to meet the
requirements of the application.

Note: EIMS work mode engine idle speed can be
adjusted by your dealer. The programmable range for
the work mode is 650 rpm to 1100 rpm. The default
work mode speed is 800 RPM.

Note: If there is an active diagnostic code on the
machine, the machine may operate at the
programmed idle speed.

Low Voltage Mode

High electrical loads from attachments may cause a
high electrical current drain on the battery. The low
voltage mode is designed to reduce the risk of fully
discharging the batteries. This feature is standard on
all machines. The low voltage mode is engaged after
5 minutes when the following conditions are met:

• The transmission is in neutral.

• The parking brake is set.

• The throttle switch is depressed.

When the battery voltage drops below 24.5 V, the
engine speed will increase to 1000 rpm in order to
charge the battery.

The machine will return to the engine idle speed for
work mode if any of the following occurs:

• The engine fan must be greater than 77% bypass

• The transmission is in neutral.

• The throttle switch is depressed.

Note: The EIMS hibernate engine idle speed can be
adjusted by your dealer. The programmable range for
the hibernate mode is 650 rpm to 800 rpm.

The machine will return to the engine idle speed for
work mode if any of the following occurs:

• Release of the parking brake

• Directional shift of the machine

• Activation of the implements

• Push of the throttle switch

• The engine fan is at full speed

• release of the parking brake

• directional shift of the machine

Warm Up Mode

Note: If the machine is unable to regenerate during

extended idling in extremely cold ambient conditions,
engine derate and shutdown may occur.

The warm-up mode is designed to keep the engine
and the machine warmer in cold-weather operations.
The warm-up mode is engaged after 10 minutes and
the following conditions are met:

Tying Down the Machine

There are two methods that can be used to tie down a
machine. Local and/or regional regulations will

determine which method to use.

Note: Obey all local and regional governmental
regulations.

Tie Down Method

In areas where frictional lashing is not allowed, direct
lashing can be used as shown below.

Machine Retrieval

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.

Personal injury or death can result from brake
malfunction.

Make sure all necessary repairs and adjustments
have been made before a machine that has been

towed to a service area, is put back into
operation.

Do not use a chain for pulling. A chain link may break
causing 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 and break
the tow line or the tow bar. 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.

Connect a larger machine or additional machines to
the disabled machine in order to provide sufficient
control and sufficient braking. Control of the disabled
machine must be maintained at all times.

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.

NOTICE
This machine is not designed to allow for towing of at­tachments. The hitch is for machine retrieval only.

To perform the towing procedure properly, use the
following recommendations.

This machine is equipped with spring-applied, oil
pressure released parking brakes. If the engine or the
brake oil system is inoperable, the parking brakes are
applied and the machine cannot be moved.

Use these towing instructions for moving a disabled
machine over a short distance of 8 kilometers

(5 miles) 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.

Do not allow riders on a machine that is being towed
unless the operator can control the steering and/or
the braking.

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 the tow bar must have a strength that
is equal to 1.5 times the gross weight of the machine
being towed.

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.

system while the machine is being towed.

Reference: For information about the manual
release of the parking brake, refer to Operation and
Maintenance Manual, “Parking Brake Manual
Release”.

Refer to Special Publication, NENG2500, “Dealer
Service Tool Catalog” for tools and supplies suitable
to collect and contain fluids on Cat products.

Dispose of all fluids according to local regulations and
mandates.

4. Fasten the tow bar or the tow line between the
disabled machine and the towing machine.

5. Tow the machine slowly. Do not exceed 3 km/h
(2 mph).

(A) Rod end. (B) Head end.

Perform the following steps before you tow the
machine.

1. Reverse the hydraulic steering hose connections
on one cylinder only allowing the steering cylinders
to move freely.

Note: Make sure that the cylinder hoses are
connected correctly before you operate the machine
again. The steering system will not function if the
hose connections are reversed.

2. If failure of the internal transmission or of the drive
train is suspected, remove the center drive shaft
and remove the rear drive shaft.

Reference: For the removal procedure for the drive
shafts, refer to the Disassembly and Assembly
manual for the power train or consult your Prentice
dealer.
