WORK SAFELY – FOLLOW THESE RULES

This symbol and text with bold letters is used throughout this manual t o call your
attention to instructions concerning your personal safety. Observe and follow
these instructions. Be certain anyone operating and servicing this machine is
aware of these rules. Fail ure t o fol low these rules may result in injury or death.

WARNING: The machine can only be operated by a person who is familiar with
this manual, knows operation of the machine and its mechanisms, experi enced
and properly licensed to operate such machines. Carefully observe and follow all
instructions provided in this manual.

The instructions and information given in this section do not cover all you ought to k now to operate
the machine safely. Detailed instructions regarding operational safety appear in the following
sections of this manual.

Human error is an important factor in most equipment-related injuries. Haste, carelessness and
lack of training are the primary causes of injuries.

Most operating injuries occur because of excessive speed, loss of control, failure to observe
warning signs, slipping or falling while entering for dismounting, a lack of barms on roadways or
piles, lack of a ROPS or seat belt , or not watching in the direction of travel.

Most maintenance injuries occur during welding or when using hammer s or wrenches. The most
common faults are improper work posit ion, a slipped tool, missed aim, a broken tool, f lying chips
and no welding hood.

Think before you act. A careful operator or maintenance man is the best insurance against an
accident.

Always wear proper safety equipment.
Avoid wearing jewelry and loose fitting clothing; they could catch on moving parts, which could

result in serious injury or death. Hard hat, sturdy rough-soled work shoes or safety shoes, ear
protectors, reflective clothing, safety glasses and heavy gloves may be required. Consult your
employer for specific saf et y eq uipm ent requirements.

Each job site and application may have personal safety requirements. Carefully evaluate your
particular application and machine for equipment such as heater and defroster, all windshield
wipers, warning lights, side view and rearview mirrors, back-up alarms, fire extinguisher, rotat ing
beacons and additional lights. If in doubt, contact your distributor.

The machine should be equipped with a fully charged fire extinguisher. All personnel should be
instructed in fire extinguisher proper usage. Recharge immediately af t er use.

If a machine is equipped with a GRAMMER operator’s seat, the fire extinguisher is placed in a
operator’s cab to right of his seat . Fig. 2.1 shows the fire extinguisher location.

machine's frame away from the battery.

4. To remove cables, reverse above sequence exactly to avoid sparks near the batter y.
A frozen battery can explode when the booster cables are attached.

NEVER check battery charge by placing a metal obj ect across the bat tery posts. T he spark s could
cause an explosion. Use a voltmeter or areometer for checking. Every machine is factory
equipped with a fire extinguisher, fir st aid kit and safety belt.

2.2. BEFORE STARTING THE ENGINE

Never start the engine indoors unless proper exhaust ventilation is provided to remove deadly
exhaust gases. Once the engine is operating , move the machine outdoors as soon as possible.
Exhaust gases are dangerous and can cause unconscious-ness and death.

Always place the gear selector in neutral, apply neutral safety lock and lock the parking brake
before starting the engine.

The operator must be alert, physically fit and free from the influences of alcohol, drugs or
medications that might affect his eyesight, hearing, r eact ions or j udgement.

Observe and know the use of alternate exits from the operator compartment .
Safety must always be the operator's most impor tant concern. He must ref use to operat e when he

knows it is unsafe and consult his supervisor when safety is in doubt. The best saf ety device is a
safe operator.

Do not use controls or hoses as hand holds when climbing on or off the machine. Hoses and
controls can move and do not provide solid support. Movement of the controls may cause
inadvertent and unexpected movement of the machine or its equipment.

Follow all machine-mounted safety signs before starting, operating, maintaining or servicing the
machine.

Be sure the area of the operator 's compartment, all mounting steps and grab handles are f ree of
oil, grease, loose objects, ice and m ud to lessen the possibility of slipping. Remove or secure all
maintenance and personal items so they will not interfer e with the operator or jam the controls.

Perform a visual check of the machine before starting the engine. Look for such things as
improper fluid levels, oil leaks, and loose, damaged or missing parts. Do not star t the engine until
any unsafe conditions are corrected. Secure all caps and filler plugs.

MAINTENA NCE

Excessive or repeated skin contact with sealant or solvents may cause skin irritation. In case of
skin contact, remove sealant or solvent promptly by washing with soap and water. Follow the
manufacturer’s advice whenever cleaning agents or other chem icals ar e used.

Lower blade and ripper before making hydraulic adjustments. T o prevent personal injury, be sure
no personnel are standing in the way of the blade and/or ripper when it is being lowered.
Never allow anyone to walk under or be near unblocked raised equipment.

Provide proper ventilation when operating in a closed building to avoid danger of exhaust gases.
Exhaust gases are dangerous and can cause unconsciousness and death.

Hydraulic fluid escaping under pressure from a very small hole can be almost invisible, yet have
sufficient force to penetrate the skin. Use a piece of cardboard or wood to search for suspected
leaks. Do not use hands. If injured by escaping fluid, see a doctor at once. Serious infection or
reaction can occur if proper medical treatment is not administered imm ediately.

Wear proper protective equipment such as goggles or saf ety glasses with side shields, hard hat,
safety shoes and heavy gloves when metal or other particles are apt to fly or fall.

Lift and handle all heavy parts with a lifting device of pr oper capacit y. Be sure parts ar e secured by
proper slings and hooks. Use lif t ing eyes if provided. Warn people in the area to stand clear.

Do not attempt to repair a protective structure after an accident. Repaired structures do not
provide the original strength and protection. Contact your distributor for inf ormation on structure
replacement. Do not operate the machine again until the ROPS has been replaced.

When using com pressed air for cleaning parts, wear gog gles or safety glasses with side shields.
Use a air nozzle, which limits the pressure to 200 kPa.

Do not use an open flame to check f or leaks or fluid levels anywhere around the machine.
Keep work area clean and dry. Remove oil and water spills immediately.

Do not pile up oily or greasy rags. They are a fire hazard. Store them in an approved, closed met al
container.

Use a soft iron or nonferrous hammer to install or rem ove ripper teeth. It is danger ous to hammer
on the teeth. Wear safety glasses with side shields or gogg les t o r educe the chances of injury.

Batteries give off a hig hly inflammable gas. Never allow sparks or open f lam e near the batteries.
A fire or explosion could occur. Do not charge bat t eries in a closed area. Provide proper ventilation
to guard against accidental explosion of an accumulation of the explosive gas given off in the
charging process.

When installing batteries, be sure the electrical master switch is in the "o ff" position. Be sure to
connect the positive cable to the positive terminal and the negative (ground) cable t o the negative
terminal.

Ether starting fluid is f lam mable. Follow the precaut ions print ed on the cont ainer. An explosion can
result if sparks or f lame contact the ether in t he container or if the container is stor ed in an area in
which the temperature exceeds 70°C. Observe the following precautions:

Never mix gasoline, gasohol or alcohol with diesel fuel. This cr eates an extreme fir e or explosion
hazard, which could result in personal injury or death.

Do not use bleach, color dye or solvents on the seat belt webbing. This m ay cause a severe loss
of tensile strength. This could cause the webbing to break resulting in personal injury. It is
recommended that the seat belt be cleaned only with warm water and mild deterg ent .

2.5. WHEN PARKING

If parking on or near traff ic lanes cannot be avoided, provide appropriat e flag s, barriers, flares and
warning signals. Also provide advance-warning signals in the traffic lane for approaching t raffic.
Park the machine in a non-operating and non-t raf f ic ar ea. Park m achine on level ground whenever
possible. If you must park on a slope, par k at right angles to the slope. Apply and lock t he brake
pedal.

Never leave the machine unattended with the engine running.
When leaving the m achine unattended, slowly lower the hydraulic equipment to the ground, shif t

the transmission into neutral and lock the neutral lock lever, shut of f the eng ine, apply and lock the
parking brake. Relieve any pressure in the hydraulic system by moving the controls in both
directions. Turn off the electrical system master switch and take it out. Always lock up machine
when leaving it unattended, including any anti-vandalism attachments.

Do not jump off t he machine.
When operating in bad weather and storm lightening is nearby, dismount and seek shelter away

from the machine. Lightening will be attracted to the machine and can cause serious injury or
death.

When the machine is to be loaded onto a transport truck and trailer do so carefully. Load only
when the trailer is level. The steel track shoes will slide easily on the t railer. W hen t he machine is
properly positioned chain it securely and block with wooden pieces so it can not move on the
trailer.

Keep your head, body, legs, hand, fingers away from the blade and ripper when they are in a
raised position.

Do not allow the hydraulic system to support the mounted equipment without its proper blocking
when leaving the machine unattended, to eliminate the possibility of an expected drop of the blade
or ripper.

4.1. MACHINE PRECAUTIONS

During operation stay alert and watch what you are doing. Use common sense and do not operate
when fatigued.
Know your machine. For your personal safety read this manual caref ully and f ollow all instructions
and precautions. Refer to and read Sect ion 2 carefully and follow all precautions.

Before starting or operating this tract or, read the following general precautions. These are listed
there to help you protect the machine and to remind you of protection for yourself and those
around you. Sound judgment and observance of these rules will help make your job a safer one.
Visually check out the machine for leak s and broken, missing or malfunctioning parts. Be sur e all
caps, dipsticks, battery covers, etc. are secure before starting. Correct any problems before
operating the machine.

Keep the transmission in low gear when going downhill. Never coast downhill with the transmission
in neutral. The machine could go out of control and tip over. Always drive the machine slowly when
on hillsides, ramps or rough terrain. Be extremely careful when working around t renches or bank s.
Failure to do so could cause the machine to roll over.

Before starting operation, check the machine for correct function of steering controls, brake
controls, hydraulic controls, instruments and safety equipment. Make all necessary repairs or
adjustments before operat ing the machine.

Do not place the tractor under load without the proper engine oil pressure and operating
temperature. After starting the engine, move the engine speed control lever to the low idle
position.
Allow the engine to run at low idle for 3 to 5 minutes at 1000 RPM until normal oil pressure
registers on the gauge t o obtain complete distribution of the lubricating oil.
Oil pressure after 15 seconds must be cor rect. To prevent any possible damage to the alternator ,
the electrical system master switch must be in the “ ON” position when the engine is running. T he
switch must be in the “OFF” position only when the engine is shut down at the end off each day or
when the operator leaves the tractor unattended.

If the tractor is left outside during cold weather and t he tracks become frozen to the ground, do not
attempt to jerk them f ree with the power of t he engine. Star t the tr actor slowly and, if t he track s do
not break free, pry them loose. To prevent the tracks f rom fr eezing in the ground, park the tractor
on planks.

In freezing weather thoroughly clean all ice and mud from the track system after each day's
operation to prevent freeze-up of the system. Be sure to clean the seal area off the sprocket
drives, front idlers, t op idler s and r ollers.

Never pour cold coolant into the radiator if the engine is very hot unless conditions make it
absolutely necessary. Use extreme caution as hot coolant could burn you. Keep face away from
filler neck. Under such conditions, start the engine and let it idle while slowly pouring the coolant
into the radiator. Allow the engine to cool down to 50°C.
Pouring cold coolant into the engine may result in dam age to cast components of t he engine.

Never use water alone in the cooling system.
Fill the fuel tank at the end of each day's work to reduce moisture condensation in t he tank.
When using a long chain or cable to hitch the tractor to the load, drive the tractor forward slowly
until all slack is taken out.
Before shutting down, operate the eng ine at half speed (no load) f or t hree to five minutes. This will
aid in cooling the engine and turbocharg er .

4.19. OPERATING TECHNIQUES

WARNING! Before operating the machine, be sure the area of the operator's
compartment, all mounting steps and grab handles are free of oil, grease, loose
objects, ice, snow and mud to lessen the possibility of slipping. Remove or secure
all maintenance and personal items so they will not interfere with the operator or
jam the controls. Failure to follow these instructions may result in serious injury.

When the blade is held hydraulically it becomes a r igid part of the t ract or, except when the valve is
in “FLOAT” position, and will follow all movements of the tractor. W hen rough terrain encounter ed
it will be necessary to vary the height of the blade while pitching to obtain a smooth cut. When
possible, start all jobs from relatively level ground. If necessary, level an area large enough to
provide sufficient working space f or the tractor. This prevents back and forth pitch of the tractor
and will result in easier digging.
Avoid track spinning whenever possible; this wastes effort and converts a relatively smooth
working area into ruts and piles that pitch and t ilt a t ract or. I n cold weather this mat erial can f reeze
and cause additional difficulty the f ollowing day.
Crossing ditches, ridges, r ock or logs should be done slowly and, at an angle. This slows the f all,
lessens the danger of upsetting the machine and reduces the f all jolt, which can be har mful to the
operator and machine.

4.19.1. DIGGING AND CLEARING

WARNING! Prior to operating know the locations of gas lines, utility lines, sewers,
overhead and buried power lines, and the other obstructions or hazards are
known. A raptured gas line or cut electrical line coul d resul t in personal injury.

OPERATING TECHNIQUES

Always feed the blade into the ground gradually until t he desired depth of cut is obtained. W hen
selecting the gear range and det ermining the depth of cut, allow for an increase in resistance as
the load increases. W hen raising the blade at the end of a cut, do it gradually t o avoid an abrupt
ridge or bump in the path of the tractor. Move material downgrade whenever possible to take
advantage of the reduced effort required (Fig. 4.29).

Fig. 4.29. Moving Material Downgrade

Two methods of cutting down a pile or hill are shown in Fig. 4.30. Type of material and local
conditions may dictate which method is preferred. Further infor mation is included in “BREAKING
PILES AND SPREADING” W hen using Method l, never allow the hig h face t o become a hazard to
the operator or machine. W ith the tract or at right angles to the f ace, raise the blade and dislodge
the high bank before r eturning to the original dir ect ion of cut.
When using Method 2, m ake the cut wide enough to avoid trapping the tract or .

WARNING! Avoid high overhangs. Ramp up and remove the top layers first.
Avoid high banks. Operate the machines as far away from the trench as possi ble
or cave-in may result.

A side-hill cut can be started more easily if a sm all bench cut is first made as shown in Fig. 4.31.
Then, when digging as in Fig. 4. 32, keep the inside (uphill) surface slig htly lower to gain greater
tractor stability. Tilting the blade will provide this type of cut with less effor t on the operator's part.

Always cut the shelf wide enough to provide solid support for equipment using it later. I f possible,
move the material downhill to gain the advantage of gravity, reduced eff ort and increased tractor
stability. Soft soil or shallow slopes may allow the side hill cut to be made as shown in Fig. 4.33.
Increased stability is realized by running the uphill track inside t he ridg e lef t by the f irst cut . Cut s 3,
4 and 5 illustrate the completion of t he shelf.

Fig. 4.33. Shallow Slope Side Hill Cut

Once again, pushing the loosened mater ial to the lower side of the slope will normally reduce tim e
and cost. Do not push material beyond the point requir ed to retain firm track support.

Fig. 4.34. Slope Edge Operation

When backing up, do not raise the blade as this puts extra weight on the front idlers causing
greater track penet r at ion. Let the blade float as you back away from the edge of soft fills.
Initial work on steep hillsides can be safer by either secur ing the tractor with a winch to a suitable
uphill anchor point or by operating a tandem arrangement as shown in Fig. 4.35.

OPERATING TECHNIQUES

When clearing trees, raise the blade high to gain leverage and make contact gently to reduce
possible harm to the operator and machine (Fig. 4.36).
Heavy roots of large trees may requir e pushing and digging or cutting from several sides of the
tree. Use a cable to topple and remove trees from soft ground (Fig. 4.37).

Fig. 4.36. Machine Equipped with Sweeps

Fig. 4.37. Using Cable to Remo ve Trees

WARNING! Falling trees and dead limbs can cause injuries. When clearing trees,
operator protection must be used.

When clearing a rock y area, r emove the small and loose r ock s f irst, larg e and solid rock s can then
be loosened and moved with less difficulty. W hen loosening larg e or solid rock s, great er f orce and
penetration can be obtained by tilting the blade and prying under the rock with the lower edge of
the blade (Fig. 4.38). Lifting the rock with the blade while pushing will increase traction and r educe
track spinning

DRESSTA TD-40C

SECTION 4 OPERATING

Page 36

OPERATING TECHNIQUES

Penetration on hard, frozen or rock y ground can be made easier by tilting t he blade. This will add
weight and power to the lower cutting edge. When the ground is frozen and the area must be
ripped before it can be worked, rip a relat ively small section and work it t o grade bef ore enlarging
the cut. This will require ripping each sect ion only once, not every morning after the ground has
refrozen. Snow can act as an insulating blanket and reduce or eliminate the need for a ripper.
Therefore, remove snow only from the area to be worked each day; leave the rest to insulate the
ground.

4.19.2. TRANSPORTING, PILING OR LOADING

The transporting of material with a bulldozer is not always a most economical method. Natural
ridges, a window formed by side blade spillage on earlier passes or side-by-side, dozing will
improve the productivity (Fig 4.39). W here the quantity of mat erial or distance involved becomes
excessive, a loader, scraper or truck should be considered.

Fig. 4.39. Side-by-Side Dozing

A usual method of piling is shown in Fig. 4.40. When the piling r eaches st ages
“D” or “E” the operator may elect t o cont inue one of the ot her depending on height or area desired.
When the tractor is used as a pusher, aiding scraper loading (Fig . 4. 41), t he tr actor power must be
carefully controlled. Excessive “push” eff ort can cause the scraper unit t o “j ackk nif e” , with result ing
injury or damage. On turns, be sure the blade of the pusher tractor does not com e in contact with
the rear wheels of the scraper.

4.19.3. BREAKING PILES AND SPREADING

Two methods of breaking down a pile are shown in Fig. 4. 43. When spr eading is to be in several
directions or if the pile is large or hard, Method 1 is usually desired. When using Method 1, cut int o
the side of the pile from different angles. When Method 2 is used, and access to the top of t he pile
is difficult, a slot may be started as shown below. Loosen material at the base and form a dirt
“ramp” to provide a decreased angle of approach and cut.

Method 2

Fig. 4.43. Breaking Down a Pile

2. Original Slope

When trucks or wagons are used for hauling, bulldozers are ideal spreading tools at the fill
(Fig. 4.44). Blade should be kept in a straight position so that material is drif ted directly under the
cutting edge (Fig. 4.45). When finishing in non-solid materials, such as earth, drag the blade
backward for a smooth job as shown in Fig. 4.45. Rock, of course, may damag e the blade base,
therefore, such practice is not r ecom m ended where abrasive mat er ial is common.

4.19.4. RIPPING

4.19.4.1. Prior to Operation

Before operating the r ipper proceed as follows:

1. Check all mounting hardware for t orque.

2. Check hydraulic connections for leaks.

3. Check the condition of the ripper, bit s , mounting hardware for completeness and t or que.

4.19.4.2. Ripping Techniques

When starting ripping lower the ripper teeth slowly to required depth. Ripping of r ock mater ial must
be performed in direction of easier ripping what may be established by carrying out t est ripping in
various directions and under various angle of inclination of the shanks. During t est ripping lower
the shank to half of working depth. Machine eff iciency can be improved when several centimeters
of loose material is left on solid r ock. Ripping should be perf ormed at a depth the best results are
obtained without overloading the engine. Keep loose ground level and horizontal as mach as
possible. Never make turns with the machine with ripper teeth are at full depth in rocky ground.
Use the common sense when working in hard ground not to damag e the ripper and the machine.
Do not accelerate the machine and simultaneously lower the ripper teeth into the gr ound – this will
damage the ripper.
Pay attention not at allow rear of the machine t o lift off t he ground during ripping operat ions, as
this decreases traction and accelerates wear of track system. Use new and sharp bits for hard
ground.

4.19.5. COLD WEATHER OPERATION

Start the engine as described in “ST ARTING THE ENGINE” and then proceed as follows:

– move slightly and slowly ripper control to warm oil in hydraulic cylinders.
– raise the ripper at max. height and t hen lower it slowly until it rest s on the ground.
– incr ease gradually pressure in ripper cylinders by keeping the control lever in LOWER position

until rear of the machine is off the ground.

– prior to normal ripping operations operate the r ipper at low depth for a couple of minutes to

warm shank bits.

– protect shank and bits when parking the m achine.

4.20. ECONOMICAL OPERATION OF THE MACHINE

Fuel consumption during operation of the dozer depends on many factors as: engine
characteristics, load, terrain, oper ator’s skill and experience, manner of oper at ion.
Relatively of fuel consumption is quantit y on moved material per unit of consumed fuel. To r each
the most favorable value of this ratio observe the following principles of dozer operation:

– Avoid long distance transporting of m at e r ial.
– Loading and pushing of material must be per formed at g ear which ensures maximum drawbar

pull (1

– Reverse travel at top gear but keep eng ine speed above medium , not maximum.
– Avoid stopping machine due stall of the engine.
– Avoid track slippage.
– For digg ing hard material pitch the blade for ward, for transpor tation of mater ial pitch the blade

backward.

5.4. LUBRICATION

Front idlers, track idlers and track rollers ar e permanent ly lubricated with a SAE30, API CD or MIL­L-2104C engine oil.
A level check of these compartment s is not r equired.

5.4.2. WHEN SERVICED
WARNING! When you service the machine, always follow the Operator's or

Service Manual. Never grease, oil or perform any maintenance alone with the
engine running. Always have another experienced person helping in the
operator's compartment when maintenance must be done with the engine
running. Block up all attachments securely. Do not leave the operator's seat
with the engine running. Failure to follow these instructions could result in
serious injury or death.

The life and perform ance of a tractor and its equipment depends on the service that it is given.
Proper lubrication is an important part of the maintenance service. Thorough lubrication service
performed at specified intervals will aid in prolonging the life of the t ractor and its eq uipm ent and in
reducing operating expense. The type of work being done, load, gr ound and weather conditions
are all factors to consider in frequency of lubrication.

The scheduled intervals between lubrication periods shown on the “SERVICE CHART” are
approximate, based on average operating conditions. It may be necessary to lubricate after
shorter working periods under severe operating conditions such as extremely dusty, low engine
temperatures, intermittent operation, excessively heavy loads with high oil temperatures, or when
diesel fuel with a high sulfur content is used. However, the time intervals between lubrication
periods must never exceed those indicated in this manual.

5.4.3. SELECTION

The selection of the proper type (specification) and the gr ade (weight or viscosity) of lubricant is
important. Many tests have been made to determine the correct lubricant s for this tractor and its
equipment.

5.4.4. VISCOSITIES

During cold weather, base the selection of a crankcase lubricating oil viscosity on the lowest
anticipated temperature f or t he day to m ake starting easier.

For hot weather operation, base the selection on the highest anticipated temperature. Refer to t he
"REFILL SPECIFICATIO NS AND CAPACITIES CHART”.

IMPORTANT: After changing oil or break in operation for more that 5 days follow the below

5.5. SEASONAL PREPARATION

General

Mechanical efficiency is enhanced during seasonal air temperature changes, when these
instructions are followed.

Outside source of heat

Machines left outside for prolonged periods in sub-zero weather will suffer from "cold-soak."
Lubricants become viscous and incapable of lubricating moving parts. Extreme wear could result
to the engine, transmission and f inal dr ives unless proper precautions are taken.

A source of outside heat is necessary under these conditions. There are electric as well as
propane-fired engine coolant heater s available. Gas-fired f orced air heaters may also be obt ained
to heat the transmission and final drives.

When using such heat er s follow manufacturer’s safet y instructions.

WARNING! For your personal safety, use caution and foll ow t he manufacturer's
instructions when using engine block heaters to warm the coolant or external
heaters to warm the tractor

5.5.1. FUEL SYSTEM

Refer to "FUEL SYSTEM" for the diesel fuels selection, which will give the most satisfactory
performance.

5.5.2. COOLING SYSTEM

Prepare the cooling system as follows:

1. Check t he ent ire engine system for leaks.

2. Inspect t he condit ion of all hoses and replace the hose and hose clamps as necessary.

3. Clean cooling system . Refer to “CLEANING THE SYSTEM.”

4. Check t he dr ive belt tension and adjust tension or replace belt. Refer to “ENGINE MANUAL”.

5. Remove all debris f rom the radiator core using air or water under pressure. Direct the flow
through the core, opposite the nor mal direction of air flow.

WARNING! For your personal protection, w at er pressure should not exceed 275
kPa and air pressure should not exceed 210 kPa. Use safety goggles.

6. Clean the radiat or guard and outside of the core.

7. Protect your cooling system fr om damage by using approved antif reeze and coolant. Refer to
“FILLING THE DRAINED SYSTEM”.

8. Keepyour cooling system clean and minimize corrosion by changing the coolant filter at
correct intervals. Refer to “COOLING SYSTEM.”

9. Check t he condit ion of fan blades. Lubricate fan hub (QSK-19 Engine)

5.5.3. ELECTRICAL SYSTEM

Clean batteries and remove all corrosion from the battery terminals and cables. Repair or replace
all wires, which have worn, cracked or frayed insulation and broken or loose wires. Service the
batteries.

5.6. AIR CLEANING SYSTEM

5.6.1. AIR CLEANER

This machine has a „dry-type” cleaner with replaceable elements.
The cleaner has two elements: primary and safety. The primary can be cleaned for a limited

number of times before replacem ent is necessary, however, the safety element must be replaced
when plugged. Detailed service procedures for t his air cleaner are covered in the following text.

IMPORTANT: As a precaution against dirt entering the engine, all gasket and rubber hoses
between the air cleaner, turbocharger and intake manifold, and betw een the manifold and cylinder
head must be in good condition and the joints or connections must be tight. Never operate the
engine unless a filter element is in place and filter end gasket is installed. Never remove the
element from the air cleaner or ser v ice t he air cleaner while the engine is running.

5.6.2. PRIMARY FILTER ELEMENT

Service

The air cleaner primary element must be serviced whenever indicated by the air cleaner filter
warning light. Ref er to "AIR CLEANER FILTER WARNING LI GHT".

If after perf ormed cleaning of primary f ilter element the air cleaner f ilter-warning light cont inues to
glow, check for allowable restriction, precleaner screen. If the warning cont inues to glow replace
safety filter element. I f with cleaned primary filter element and replaced safety filter element the
warning light still continues to glow, check air cleaner service indicator. The primary element can
be cleaned by either of two methods: washing or compressed air. Washing is the preferred
method as it removes more dust and soot and restor e t he elem ent to an almost new condition.

The result being better per formance and longer intervals between required element ser vice. It is
recommended that a spare element be obtained for use while the serviced element is drying.

IMPORTANT: The primary filt er element must be replaced after six washing.

Cleaning the element with compressed air is not considered an entirely satisf actor y met hod. Some
dust will remain in the element causing more frequent servicing of the element. Cleaning with
compressed air should be used only as a temporary measure until suf ficient time is available to
clean the element by washing. Engine air intake system (hoses, clamps, rubber connectors) is
recommended to be checked for leaks ever 50 hours of operation.

IMPORTANT: After cleaning, if an element is to be stored for later use, place it in a plastic bag
and store in an element-shipping container to protect against dirt and damage.

Removal (Fig. 5.2)

1. Stop the eng ine. Lower equipment on the ground. O pen left engine access door. Remo ve all
dust from the element r em oval end of the air cleaner body

2. Release tree lock straps and remove cover (8) from the air cleaner body (1), unscrew the
wing nut (5) remove gasket (9) and carefully remove the primary element f r om t he body not to
dislodge dust from the dir t y element onto the primary element (2).

remove the soot.

Washing

IMPORTANT: Never wash elem ent in fuel, oil, gas or solvent. DO NO T OIL ELEMENTS. Do not
tap the element against a hard surface; this will damage the element.

1. Carefully tap the side or end of the element against the palm of your hand to remove loose
dust.

2. Wash the element in clean, warm water 20°C to 40°C. A small amount of nonsudsing
detergent added to the water will remove the soot.

3. Rinse the element in clear water ( if a hose is used, do not exceed 275 kPa).
Shake the element carefully to re m ove excess water.

5.6. AIR CLEANING SYSTEM

IMPORTANT: Do not use compressed air t o speed the drying of the element; the air pr essur e will
rupture the wet element.

4. Lay the element on its side and allow it to air-dry before reinstalling. Overnight drying is
usually sufficient. When drying the element, pr otect it from dirt and/ or freezing

NOTE: If no spare element is available, the wet element, after excess w ater has been shaken out,
may be installed in the air cleaner and the engine operated at idle for 10 minutes before operating
the tractor.

5. Inspect for damage. Refer to “INSPECTION.”

Inspection

1. Inspect the filter element for leaks or damage by placing a bright light inside the element.
Inspection of the element on the outside will disclose any holes where concentrated light
shines through. The slight est r upture requires replacement of the filter element .

2. Inspect the contact surfaces of the air cleaner body. If faulty or damaged surf aces are noted,
correct these conditions immediately.

Installation (Fig. 5.2)

1. Insert the open end of the primary element (3) into the air cleaner body (1) and secure with
the washer (4) and wing nut (5). Installs cover (8) with gask et (9) onto the air cleaner body.
Secure the cover to the body with locking clamps making sure cover is not cocked.

2. Inspect and tighten all air cleaner connections before resum ing operation. Start the engine. If
the air cleaner, filter warning light indicates air restriction, replace primary or primary and
safety filter element s.

5.6.3. SAFETY FILTER ELEMENT

Service

Replace the safety element with every third change of the primar y element or when plugged, as
shown by the filter warning light.

Removal (Fig. 5.2.)

1. Remove primar y element . Refer to 5.6.2.

2. Remove cotter key (7), nut (6) and washer (4) and pull safety element from body. Clean
inside of body (1) with a damp cloth. Check the condition of gasket on the end of the saf ety
element. If the gasket is damaged or missing, r eplace the gasket.

5.8. COOLING SYSTEM

General

The cooling system operates under pressure. T he water pump circulates the coolant throug h the
oil cooler, engine block, cylinder heads, and radiat or. Circulation is controlled by the thermostats,
which prevent coolant flow through the radiator until the engine reaches operating temperature.
Proper cooling is as assured only when the system is sealed, radiator cap and gasket in good
condition, thermostats operate properly, system is free of coolant and/ or air f loor restr ictions and is
filled to proper level.

Selection and maintenance of the system coolant is important to long engine life. The following
information provides recommendations for selecting the engine coolant, maintaining the coolant
inhibitors, and servicing the cooling system. This system will operate with a water/antifreeze
mixture or inhibited water as a coolant. Never use water alone because water will allow rust, scale
deposits, and corrosion to occur within the system.

5.8.1. WATER

Use water, which has a low mineral content. Water used in conjunction with antifreeze, coolant
filters and inhibited water must meet the following standards:

Total hardness: Not to exceed 170 parts per million to prevent scale deposits. W ater containing
dissolved magnesium and calcium (the usual reason for water hardness) above the specified
amount will cause scale deposits to develop in the engine.

Chlorides – Not to exceed 40 parts per million to prevent cor rosion.
Sulfites – Not to exceed 100 parts per million to prevent corrosion.
Dissolved solids – Not to exceed 340 parts per million to minimize sludge deposits, scale

deposits and corrosion.
If any of the requirements cannot be met, use distilled de-ionized or de-mineralized water. To

determine if local water supplies meet these standards, water treatment laboratories can test
water samples. Softened water that is prepared using common salt (sodium chloride) contains
excessive amounts of chlorides and should not be used.

5.8.2. ANTIFREEZE

Low silicate ethylene glycol antifreeze is recommended. The antifreeze should contain no more
that 0.1% anhydrous alkali metasilicate. Low silicate antifreeze is recommended to avoid the
formation of silica gel (hydro-gel). This g el formation can occur when cooling system contains an
over concentration of high silicate antif reeze and/or supplemental coolant additive. DO NO T use
methanol or alcohol as antifreeze because of its low boiling point. Antifreeze may r etain its f reeze
protection for more than one season but coolant conditioners must be added to maintain corr osion
protection. Antifreeze for mulated with metoxy propanol, or propylene glycol is not recommended
for this system.

IMPORTANT: Do not mix types of antifreeze solutions. Mixed solutions make it impossible to
determine the protection against freezing. Antifreeze containing sealer or anti- leak additives should
not be used in this system. Sealer or anti-leak additives will plug the coolant filter and cause
plugging problems in the cooling system.
