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.

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 29 g00702020

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.

Illustration 31 g02159053

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:

20 SEBU8707

Safety Section
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

Sulfuric Acid Burn Hazard may cause serious per­sonal injury or death.

The exhaust gas cooler may contain a small
amount of sulfuric acid. The use of fuel with sulfur

levels greater than 15 ppm may increase the
amount of sulfuric acid formed. The sulfuric acid

may spill from the cooler during service of the en­gine. The sulfuric acid will burn the eyes, skin and
clothing on contact. Always wear the appropriate
personal protective equipment (PPE) that is noted
on a material safety data sheet (MSDS) for sulfuric
acid. Always follow the directions for first aid that
are noted on a material safety data sheet (MSDS)
for sulfuric acid.

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 that the coolant level after the engine has
stopped and the engine has been allowed to cool.

General

Much of the material found in forestry applications is
highly flammable, including limbs, bark, leaves, saw
dust, small wood chips and pine needles. When the
forestry debris is soaked with fuel or lubricants, the
risk of fire is greatly increased SEBD1901. Doing a
daily inspection before every shift, or more often
based on the work activity and build-up of debris, is
the best way to prevent a machine fire. Frequent
inspections and thorough machine cleaning are
critical when engaged in forestry operations. Even
minor leaks or electrical malfunctions should be

repaired as soon as possible. SEBD1901

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.

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

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

22 SEBU8707

Safety Section
Fire Prevention and Explosion Prevention

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. Highly
flammable debris such as leaves, twigs, saw dust,
small wood chips and pine needles can collect on
and in equipment used in forestry operations. If
allowed to accumulate, the debris can rapidly become
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
on the machine at eh completion of each work shift or
more frequently when working in conditions where
large amounts of forest debris are present.

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.

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.

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.

Illustration 34 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.
Properly clean areas of spillage.

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

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.

Battery and Battery Cables

Illustration 35 g02298225

Prentice recommends the following in order to
minimize the risk of fire or an explosion related to the
battery.

Do not operate a machine if battery cables or related
parts show signs of wear or damage. Contact your
Prentice dealer for service.

• 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.

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. This may cause an
explosion.

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:

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

24 SEBU8707

Safety Section
Fire Prevention and Explosion Prevention

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.

Make sure that all clamps, guards, and heat shields
are installed correctly. During machine operation, this
will help to prevent vibration, rubbing against other
parts, excessive heat, and failure of lines, tubes, and
hoses.

Do not operate a machine when a fire hazard exists.
Repair any lines that are corroded, loose, or
damaged. Leaks may provide fuel for fires. Consult
your Prentice dealer for repair or for replacement
parts. Use genuine Prentice parts or the equivalent,
for capabilities of both the pressure limit and
temperature limit.

Ether

Ether (if equipped) is commonly used in cold-weather
applications. Ether is flammable and poisonous.

Follow the correct cold engine starting procedures.
Refer to the section in the Operation and
Maintenance Manual with the label “Engine Starting”

.

Do not spray ether manually into an engine if the
machine is equipped with a thermal starting aid for
cold weather starting.

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

are using an ether spray.

Illustration 36 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:

• End fittings are damaged or leaking.

• Outer coverings are chafed or cut.

• Wires are exposed.

• Outer coverings are swelling or ballooning.

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.

Consider installation of an aftermarket Fire
Suppression System, if the application and working

conditions warrant the installation.

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 37 g03275309

The recommended location for mounting the fire
extinguisher is inside on the left-hand door to the left
of the operators seat (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 cab
structure, strap the mounting plate to a leg of the cab
structure. 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 cab structure in order to install
the fire extinguisher. Also, do not drill holes in the cab
structure in order to mount the fire extinguisher.

Illustration 38 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.

26 SEBU8707

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.

Accumulator Pressure Release

SMCS Code: 5077-553-ZJ; 5077

Delimber Blade Safety

Charged accumulator can close delimber blades
resulting in sever personal injury or death. DO
NOT enter the delimber area without closing de­limber blades, shutting engine down, discharging
accumulator and blocking out tilting delimber
base frame.

Personal injury or death can result from sudden
machine movement.

Sudden movement of the machine can cause in­jury or death to persons on or near the machine.

To prevent injury or death, make sure that the area
around the machine is clear of all personnel and
obstructions before you test the machine.

Personal injury can result from hydraulic oil pres­sure and hot oil.

Hydraulic oil pressure can remain in the hydraulic
system after the engine has been stopped. Seri­ous injury can be caused if this pressure is not re­leased before any service is done on the
hydraulic system.

Make sure all of the attachments have been low­ered, oil is cool before removing any components

or lines.

The accumulator cylinder contains a bladder.
Accumulator pressure is set by pumping nitrogen gas
into the bladder through the nitrogen charge and
check port.

Discharging the Accumulator

Escaping fluid under pressure, even a pinhole
size leak, can penetrate body tissue, causing seri­ous injury, and possible death. If fluid is injected
into your skin, it must be treated immediately by a
doctor familiar with this type of injury.

Always use a board or cardboard when checking
for a leak.

NOTICE
Care must be taken to ensure that fluids are con­tained during performance of inspection, mainte­nance, testing, adjusting, and repair of the product.
Be prepared to collect the fluid with suitable contain­ers before opening any compartment or disassem­bling any component containing fluids.

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

Illustration 42 g03321206

Give the accumulator 45 seconds to purge off
pressure.

Dispose of all fluids according to local regulations and
mandates.

Delimbers mounted on a loader or trailer have
hydraulic oil pressure that must be bled from the

accumulator before performing any maintenance or
disconnecting any hydraulic lines.

Verify that machine engine id OFF.

Open purge valve in the accumulator box by turning
the purge valve handle counterclockwise.

Note: In a quiet area, the purge off will be audible.

Guards

(Operator Protection)

SMCS Code: 7000

There are different types of guards that are used to
protect the operator. The machine and the machine
application determines the type of guard that should
be used.

SEBU8707 33

Safety Section

Guards

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.

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 should be installed when a work tool
that creates flying objects is used. Mesh front guards
that are approved by Cat or polycarbonate front
guards that are approved by Cat are available for
machines with a cab. On machines that are equipped
with cabs, the window 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 Cat dealer for additional information.

Regeneration

SMCS Code: 108F

Reduction of Particulate Emissions

The Diesel Particulate Filter (DPF) will reduce
particulate emissions. The DPF collects the soot and
any ash that is produced by the combustion in the
engine. During regeneration, the soot is converted
into a gas which is released into the atmosphere. The
Ash remains in the DPF.

The temperature of the DPF must be above a
particular value in order for regeneration to occur. The
exhaust gas provides heat for the regeneration

process.

Passive Regeneration The engine provides
sufficient exhaust gas temperature for regeneration.

Controls

SMCS Code: 1000; 6461; 6640; 6700; 6700-KH;

7000; 7220

Do not weld on any protective structure. If 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.

• ECM Module - Located on the engine

• IQAN Module - Located in the cab

• XA2 Module - Located in the operators console

• Product Link Module - Located under the rear of
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

4. Disconnect power source to or remove the
following components

Engine Air Filter Primary Element - Clean/Replace

When the primary air filter element is cleaned, check
for rips or tears in the filter material. Replace the
primary air filter element after the primary air filter
element has been cleaned six times. The primary air
filter element should be replaced at least one time per
year. This replacement should be performed
regardless of the number of cleanings.

Visually inspect the primary air filter elements before
cleaning. Inspect the air filter elements for damage to
the seal, the gaskets, and the outer cover. Discard
any damaged air filter elements.

There are two common methods that are used to
clean primary air filter elements:

Illustration 127 g00101416

Cleaning Primary Air Filter
Elements

NOTICE
Prentice recommends certified air filter cleaning serv­ices available at participating Prentice dealers. The
Prentice cleaning process uses proven procedures to
assure consistent quality and sufficient filter life.

Observe the following guidelines if you attempt to
clean the filter element:

Do not tap or strike the filter element in order to re­move dust.

Do not wash the filter element.

Use low pressure compressed air in order to remove
the dust from the filter element. Air pressure must not
exceed 207 kPa (30 psi). Direct the air flow up the
pleats and down the pleats from the inside of the filter
element. Take extreme care in order to avoid damage
to the pleats.

• Pressurized air

• Vacuum cleaning

Pressurized Air

Pressurized air can be used to clean primary air filter
elements that have not been cleaned more than two

times. Pressurized air will not remove deposits of
carbon and oil. Use filtered, dry air with a maximum
pressure of 207 kPa (30 psi).

Illustration 128 g00281692

Note: When the primary air filter elements are
cleaned, always begin with the clean side (inside) in
order to force dirt particles toward the dirty side
(outside).

Aim the hose so that the air flows inside the element
along the length of the filter in order to help prevent

damage to the paper pleats. Do not aim the stream of
air directly at the primary air filter element. Dirt could
be forced further into the pleats.

Do not use air filters with damaged pleats, gaskets, or
seals. Dirt entering the engine will cause damage to
engine components.

Vacuum Cleaning

Vacuum cleaning is another method for cleaning
primary air filter elements which require daily cleaning
because of a dry, dusty environment. Cleaning with
pressurized air is recommended prior to vacuum
cleaning. Vacuum cleaning will not remove deposits
of carbon and oil.

Inspect the primary air filter element for light that may
show through the filter material. If it is necessary in
order to confirm the result, compare the primary air
filter element to a new primary air filter element that
has the same part number.

Do not use a primary air filter element that has any
tears and/or holes in the filter material. Do not use a

primary air filter element with damaged pleats,
gaskets, or seals. Discard damaged primary air filter
elements.

protective covering for storage. An air flow restriction
may result. To protect against dirt and damage, wrap
the primary air filter elements in Volatile Corrosion

Procedure for Changing Engine Oil
and Filter

Hot oil and hot components can cause personal
injury. Do not allow hot oil or hot components to
contact skin.

Park the machine on a level surface. Stop the engine.

Note: Drain the crankcase while the oil is warm. The
warm oil will allow waste particles that are suspended
in the oil to drain. As the oil cools, the waste particles
will settle to the bottom of the crankcase. The
particles will not be removed by draining the oil and
the particles will recirculate in the engine lubrication
system with the new oil.

1. The drain valve for the engine crankcase oil is
accessible by removing the lower left-hand
maintenance access cover.

Note: Refer to Operation and Maintenance Manual,
“General Hazard Information” for information on
Containing Fluid Spillage.
