Decommissioning: Proper Recycling and Disposal of Fluids and Components
Safety and environmental stewardship measures must be taken into account when decommissioning a machine and/or component. These measures include the following:
Use appropriate tools and personal protective
equipment such as clothing, gloves, face shields or glasses, during the removal or handling of objects and materials. Follow instructions for specialized components.
Release stored energy by lowering suspended machine
elements, relaxing springs, disconnecting the battery or other electrical power, and releasing pressure in hydraulic components, accumulators, and other similar systems. Minimize exposure to components which may have
residue from agricultural chemicals, such as fertilizers and pesticides. Handle and dispose of these components appropriately. Carefully drain engines, fuel tanks, radiators, hydraulic
cylinders, reservoirs, and lines before recycling components. Use leak-proof containers when draining fluids. Do not use food or beverage containers. Do not pour waste fluids onto the ground, down a drain,
or into any water source. Observe all national, state, and local laws, regulations,
or ordinances governing the handling or disposal of waste fluids (example: oil, fuel, coolant, brake fluid);
Safety
filters; batteries; and, other substances or parts. Burning of flammable fluids or components in other than specially designed incinerators may be prohibited by law and could result in exposure to harmful fumes or ashes. Service and dispose of air conditioning systems
appropriately. Government regulations may require a certified service center to recover and recycle air conditioning refrigerants which could damage the atmosphere if allowed to escape. Evaluate recycling options for tires, metal, plastic,
glass, rubber, and electronic components which may be recyclable, in part or completely. Contact your local environmental or recycling center, or
your John Deere dealer for information on the proper way to recycle or dispose of waste.

Safety
Avoid Static Electricity Risk When Refueling
The removal of sulfur and other compounds in Ultra-Low Sulfur Diesel (ULSD) fuel decreases its conductivity and increases its ability to store a static charge.
Refineries may have treated the fuel with a static dissipating additive. However, there are many factors that can reduce the effectiveness of the additive over time.
Static charges can build up in ULSD fuel while it is flowing through fuel delivery systems. Static electricity discharge when combustible vapors are present could result in a fire or explosion.
Therefore, it is important to ensure that the entire system used to refuel your machine (fuel supply tank, transfer pump, transfer hose, nozzle, and others) is properly grounded and bonded. 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.

Diesel Fuel

Fuels, Lubricants, and Coolant

Consult your local fuel distributor for properties of the diesel fuel available in your area.
In general, diesel fuels are blended to satisfy the low temperature requirements of the geographical area in which they are marketed.
Diesel fuels specified to EN 590 or ASTM D975 are recommended. Renewable diesel fuel produced by hydrotreating animal fats and vegetable oils is basically identical to petroleum diesel fuel. Renewable diesel that meets EN 590 or ASTM D975 is acceptable for use at all percentage mixture levels.
Required Fuel Properties
In all cases, the fuel shall meet the following properties:
Cetane number of 40 minimum. Cetane number greater than 47 is preferred, especially for temperatures below –20 °C (–4 °F) or elevations above 1675 m (5500 ft.).
Cold Filter Plugging Point (CFPP) should be at least 5 °C (9 °F) below the expected lowest temperature or Cloud
Point below the expected lowest ambient temperature.
Fuel lubricity should pass a maximum scar diameter of
0.52 mm as measured by ASTM D6079 or ISO 12156-1.
A maximum scar diameter of 0.45 mm is preferred.
Diesel fuel quality and sulfur content must comply with all existing emissions regulations for the area in which the engine operates. DO NOT use diesel fuel with sulfur content greater than 10 000 mg/kg (10 000 ppm).
Sulfur content for Interim Tier 4, Final Tier 4, Stage III B, and Stage IV Engines
Sulfur Content for Tier 3 and Stage III A Engines
Use of diesel fuel with sulfur content less than 1000
mg/kg (1000 ppm) is RECOMMENDED. Use of diesel fuel with sulfur content 1000—2000 mg/kg
(1000—2000 ppm) REDUCES the oil and filter change interval.
BEFORE using diesel fuel with sulfur content greater
than 2000 mg/kg (2000 ppm), contact your John Deere dealer.
Sulfur Content for Tier 2 and Stage II Engines
Use of diesel fuel with sulfur content less than 2000
mg/kg (2000 ppm) is RECOMMENDED. Use of diesel fuel with sulfur content 2000—5000 mg/kg
(2000—5000 ppm) REDUCES the oil and filter change interval. BEFORE using diesel fuel with sulfur content greater
than 5000 mg/kg (5000 ppm), contact your John Deere dealer.
Sulfur Content for Other Engines
Use of diesel fuel with sulfur content less than 5000
mg/kg (5000 ppm) is RECOMMENDED. Use of diesel fuel with sulfur content greater than 5000
mg/kg (5000 ppm) REDUCES the oil and filter change interval.
IMPORTANT: Do not mix used diesel engine oil or any
other type of lubricating oil with diesel fuel.
Improper fuel additive usage may cause damage on fuel injection equipment of diesel engines.
Use ONLY ultra low sulfur diesel (ULSD) fuel with a
maximum of 15 mg/kg (15 ppm) sulfur content.

Supplemental Diesel Fuel Additives

Diesel fuel can be the source of performance or other operational problems for many reasons. Some causes include poor lubricity, contaminants, low cetane number, and a variety of properties that cause fuel system deposits. These and others are referenced in other sections of this Operator's Manual.
To optimize engine performance and reliability, closely follow recommendations on fuel quality, storage, and handling, which are found elsewhere in this Operator's Manual.

DX,FUEL1 -19-24OCT14-1/1
To further aid in maintaining performance and reliability of the engine's fuel system, John Deere has developed a family of fuel additive products for most global markets. The primary products include Fuel-Protect Diesel Fuel Conditioner (full feature conditioner in winter and summer formulas) and Fuel-Protect Keep Clean (fuel injector deposit removal and prevention). Availability of these and other products varies by market. See your local John Deere dealer for availability and additional information about fuel additives that might be right for your needs.

Lubricity of Diesel Fuel
Fuels, Lubricants, and Coolant
Most diesel fuels manufactured in the United States, Canada, and the European Union have adequate lubricity to ensure proper operation and durability of fuel injection system components. However, diesel fuels manufactured in some areas of the world may lack the necessary lubricity.
IMPORTANT: Make sure the diesel fuel used
in your machine demonstrates good lubricity characteristics.
Fuel lubricity should pass a maximum scar diameter of
0.52 mm as measured by ASTM D6079 or ISO 12156-1. A maximum scar diameter of 0.45 mm is preferred.

Handling and Storing Diesel Fuel

CAUTION: Reduce the risk of fire. Handle fuel
carefully. DO NOT fill the fuel tank when engine is running. DO NOT smoke while you fill the fuel tank or service the fuel system.
Fill the fuel tank at the end of each day's operation to prevent water condensation and freezing during cold weather.
Keep all storage tanks as full as practicable to minimize condensation.
Ensure that all fuel tank caps and covers are installed properly to prevent moisture from entering. Monitor water content of the fuel regularly.
If fuel of low or unknown lubricity is used, add John Deere Fuel-Protect Diesel Fuel Conditioner (or equivalent) at the specified concentration.
Lubricity of BioDiesel Fuel
Fuel lubricity can improve significantly with BioDiesel blends up to B20 (20% BioDiesel). Further increase in lubricity is limited for BioDiesel blends greater than B20.
DX,FUEL5 -19-07FEB14-1/1
When using BioDiesel fuel, the fuel filter may require more frequent replacement due to premature plugging.
Check engine oil level daily prior to starting engine. A rising oil level may indicate fuel dilution of the engine oil.
IMPORTANT: The fuel tank is vented through the
filler cap. If a new filler cap is required, always replace it with an original vented cap.
When fuel is stored for an extended period or if there is a slow turnover of fuel, add a fuel conditioner to stabilize the fuel and prevent water condensation. Contact your fuel supplier or John Deere dealer for recommendations.

BioDiesel Fuel
Fuels, Lubricants, and Coolant
BioDiesel fuel is comprised of mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats. BioDiesel blends are BioDiesel mixed with petroleum diesel fuel on a volume basis.
Before using fuel containing BioDiesel, review the BioDiesel Use Requirements and Recommendations in this Operator’s Manual.
Environmental laws and regulations can encourage or prohibit the use of biofuels. Operators should consult with appropriate governmental authorities prior to using biofuels.
All John Deere Engines with Exhaust Filter (Released 2011 and After)
While 5% blends (B5) are preferred, BioDiesel concentrations up to a 20% blend (B20) in petroleum diesel fuel can be used. BioDiesel blends up to B20 can be used ONLY if the BioDiesel (100% BioDiesel or B100) meets ASTM D6751, EN 14214, or equivalent specification. Expect a 2% reduction in power and a 3% reduction in fuel economy when using B20.
BioDiesel concentrations above B20 can harm the engine’s emission control systems and should not be used. Risks include, but are not limited to, more frequent stationary regeneration, soot accumulation, and increased intervals for ash removal.
John Deere approved fuel conditioners, which contain detergent and dispersant additives, are required when using BioDiesel blends from B10—B20, and are recommended when using lower BioDiesel blends.
All John Deere Engines Excluding Exhaust Filter (Primarily Released Prior to 2012)
While 5% blends (B5) are preferred, BioDiesel concentrations up to a 20% blend (B20) in petroleum diesel fuel can be used. BioDiesel blends up to B20 can be used ONLY if the BioDiesel (100% BioDiesel or B100) meets ASTM D6751, EN 14214, or equivalent specification. Expect a 2% reduction in power and a 3% reduction in fuel economy when using B20.
These John Deere engines can operate on BioDiesel blends above B20 (up to 100% BioDiesel). Operate at levels above B20 ONLY if the BioDiesel is permitted by law and meets the EN 14214 specification (primarily available in Europe). Engines operating on BioDiesel blends above B20 might not fully comply with or be permitted by all applicable emissions regulations. Expect up to a 12% reduction in power and an 18% reduction in fuel economy when using 100% BioDiesel.
John Deere approved fuel conditioners, which contain detergent and dispersant additives, are required when using BioDiesel blends from B10—B20, and are recommended when using lower BioDiesel blends.
BioDiesel Use Requirements and Recommendations
The petroleum diesel portion of all BioDiesel blends must meet the requirements of ASTM D975 (US) or EN 590 (EU) commercial standard.
BioDiesel users in the U.S. are strongly encouraged to purchase BioDiesel blends from a BQ-9000 Certified Marketer and sourced from a BQ-9000 Accredited Producer (as certified by the National BioDiesel Board). Certified Marketers and Accredited Producers can be found at the following website: http://www.bq9000.org
BioDiesel contains residual ash. Ash levels exceeding the maximums allowed in either ASTM D6751 or EN14214 can result in more rapid ash loading and require more frequent cleaning of the Exhaust Filter (if present).
The fuel filter can require more frequent replacement, when using BioDiesel fuel, particularly if switching from diesel. Check engine oil level daily prior to starting engine. A rising oil level can indicate fuel dilution of the engine oil. BioDiesel blends up to B20 must be used within 90 days of the date of BioDiesel manufacture. BioDiesel blends above B20 must be used within 45 days from the date of BioDiesel manufacture.
When using BioDiesel blends up to B20, the following must be considered:
Cold-weather flow degradation
Stability and storage issues (moisture absorption,
microbial growth) Possible filter restriction and plugging (usually a problem
when first switching to BioDiesel on used engines) Possible fuel leakage through seals and hoses
(primarily an issue with older engines) Possible reduction of service life of engine components
Request a certificate of analysis from your fuel distributor to ensure that the fuel is compliant with the specifications provided in this Operator’s Manual.
Consult your John Deere dealer for approved fuel conditioners to improve storage and performance with BioDiesel fuels.
The following must also be considered if using BioDiesel blends above B20:
Possible coking or blocked injector nozzles, resulting in
power loss and engine misfire if John Deere approved fuel conditioners are not used Possible crankcase oil dilution (requiring more frequent
oil changes) Possible lacquering or seizure of internal components
Possible formation of sludge and sediments
Possible thermal oxidation of fuel at elevated
temperatures Possible compatibility issues with other materials

Fuel Filters
The importance of fuel filtration cannot be overemphasized with modern fuel systems. The combination of increasingly restrictive emission regulations and more efficient engines requires fuel system to operate at much higher pressures. Higher pressures can only be achieved using fuel injection components with very close tolerances. These close
manufacturing tolerances have significantly reduced capacities for debris and water.
John Deere brand fuel filters have been designed and produced specifically for John Deere engines.
To protect the engine from debris and water, always change engine fuel filters as specified in this manual.

Minimizing the Effect of Cold Weather on Diesel Engines
John Deere diesel engines are designed to operate effectively in cold weather.
However, for effective starting and cold-weather operation, a little extra care is necessary. The following information outlines steps that can minimize the effect that cold weather may have on starting and operation of your engine. See your John Deere dealer for additional information and local availability of cold-weather aids.
Use Winter Grade Fuel
When temperatures fall below 0 °C (32 °F), winter grade fuel (No. 1-D in North America) is best suited for cold-weather operation. Winter grade fuel has a lower cloud point and a lower pour point.
Cloud point is the temperature at which wax begins to form in the fuel. This wax causes fuel filters to plug. Pour point is the lowest temperature at which movement of the fuel is observed.
NOTE: On average, winter grade diesel fuel has a lower
Btu (heat content) rating. Using winter grade fuel may reduce power and fuel efficiency, but should not cause any other engine performance effects. Check the grade of fuel being used before troubleshooting for low-power complaints in cold-weather operation.
Air Intake Heater
An air intake heater is an available option for some engines to aid cold weather starting.
Ether
An ether port on the intake is available to aid cold weather starting.
CAUTION: Ether is highly flammable. Do not
use ether when starting an engine equipped with glow plugs or an air intake heater.
Coolant Heater
An engine block heater (coolant heater) is an available option to aid cold weather starting.
Seasonal Viscosity Oil and Proper Coolant Concentration
Use seasonal grade viscosity engine oil based on the expected air temperature range between oil changes and a proper concentration of low silicate antifreeze as recommended. (See DIESEL ENGINE OIL and ENGINE COOLANT requirements in this section.)
Diesel Fuel Flow Additive
Use John Deere Fuel-Protect Diesel Fuel Conditioner (winter formula), which contains anti-gel chemistry, or equivalent fuel conditioner to treat non-winter grade fuel (No. 2-D in North America) during the cold-weather season. This generally extends operability to about 10 °C (18 °F) below the fuel cloud point. For operability at even lower temperatures, use winter grade fuel.
IMPORTANT: Treat fuel when outside temperature
drops below 0 °C (32 °F). For best results, use with untreated fuel. Follow all recommended instructions on label.
BioDiesel
When operating with BioDiesel blends, wax formation can occur at warmer temperatures. Begin using John Deere Fuel-Protect Diesel Fuel Conditioner (winter formula) at 5 °C (41 °F) to treat BioDiesel fuels during the cold-weather season. Use B5 or lower blends at temperatures below 0 °C (32 °F). Use only winter grade petroleum diesel fuel at temperatures below -10 °C (14 °F).
Winterfronts
Use of fabric, cardboard, or solid winterfronts is not recommended with any John Deere engine. Their use can result in excessive engine coolant, oil, and charge air temperatures. This can lead to reduced engine life, loss of power and poor fuel economy. Winterfronts may also put abnormal stress on fan and fan drive components potentially causing premature failures.
If winterfronts are used, they should never totally close off the grill frontal area. Approximately 25% area in the center of the grill should remain open at all times. At no time should the air blockage device be applied directly to the radiator core.
Radiator Shutters
If equipped with a thermostatically controlled radiator shutter system, this system should be regulated in such a way that the shutters are completely open by the time the coolant reaches 93 °C (200 °F) to prevent excessive intake manifold temperatures. Manually controlled systems are not recommended.

Additional Recommended Coolants
The following engine coolant is also recommended:
John Deere COOL-GARD II Concentrate in a 40—60%
mixture of concentrate with quality water.
IMPORTANT: When mixing coolant concentrate with
water, do not use less than 40% or greater than 60% concentration of coolant. Less than 40% gives inadequate additives for corrosion protection. Greater than 60% can result in coolant gelation and cooling system problems.
Coolant concentrate meeting ASTM D6210
requirements in a 40—60% mixture of concentrate with quality water
If coolant meeting one of these specifications is unavailable, use a coolant concentrate or pre-mix coolant that has a minimum of the following chemical and physical properties:
Provides cylinder liner cavitation protection according to
either the John Deere Cavitation Test Method or a fleet study run at or above 60% load capacity Is formulated with a nitrite-free additive package
Protects the cooling system metals (cast iron, aluminum
alloys, and copper alloys such as brass) from corrosion
Water Quality
Water quality is important to the performance of the cooling system. Distilled, deionized, or demineralized water is recommended for mixing with ethylene glycol and propylene glycol base engine coolant concentrate.
Coolant Drain Intervals
Drain and flush the cooling system and refill with fresh coolant at the indicated interval, which varies with the coolant used.
When COOL-GARD II or COOL-GARD II PG is used, the drain interval is 6 years or 6000 hours of operation.
If a coolant other than COOL-GARD II or COOL-GARD II PG is used, reduce the drain interval to 2 years or 2000 hours of operation.
IMPORTANT: Do not use cooling system sealing
additives or antifreeze that contains sealing additives.
Other Coolants
Other ethylene glycol or propylene glycol base coolants may be used if they meet the following specification:

Water Quality for Mixing with Coolant Concentrate
Engine coolants are a combination of three chemical components: ethylene glycol (EG) or propylene glycol (PG) antifreeze, inhibiting coolant additives, and quality water.
Water quality is important to the performance of the cooling system. Distilled, deionized, or demineralized water is recommended for mixing with ethylene glycol and propylene glycol base engine coolant concentrate.
All water used in the cooling system should meet the following minimum specifications for quality:
Chlorides <40 mg/L
Sulfates <100 mg/L
Total solids
Total dissolved I hardness
pH 5.5—9.0
<340 mg/L
<170 mg/L
IMPORTANT: Do not use bottled drinking water
because it often contains higher concentrations of total dissolved solids.

Operating in Warm Temperature Climates

John Deere engines are designed to operate using recommended engine coolants.
Always use a recommended engine coolant, even when operating in geographical areas where freeze protection is not required.
IMPORTANT: Water may be used as coolant in
emergency situations only.

Testing Coolant Freeze Point
The use of a handheld coolant refractometer is the quickest, easiest, and most accurate method to determine coolant freeze point. This method is more accurate than a test strip or a float-type hydrometer which can produce poor results.
A coolant refractometer is available through your John Deere dealer under the SERVICEGARD™ tool program. Part number 75240 provides an economical solution to accurate freeze point determination in the field.
To use this tool:
1. Allow cooling system to cool to ambient temperatures.
2. Open radiator cap to expose coolant.
3. With the included dropper, collect a small coolant sample.
4. Open the lid of the refractometer, place one drop of coolant on the window and close the lid.
5. Look through the eyepiece and focus as necessary.
6. Record the listed freeze point for the type of coolant (ethylene glycol coolant or propylene glycol) being tested.

Warming Engine

IMPORTANT: To assure proper lubrication, operate
engine at or below 1200 rpm with no load for 1–2 minutes. Extend this period 2–4 minutes when operating at temperatures below freezing.
Engines used in generator set applications where the governor is locked at a specified speed may not have a slow idle function. Operate these engines at high idle for 1 to 2 minutes before applying the load. This procedure does not apply to standby generator sets where the engine is loaded immediately upon reaching rated speed.
1. Check oil pressure gauge (A) as soon as engine starts. If gauge needle does not rise above minimum oil pressure specification of 105 kPa (1.05 bar) (15.0 psi) within 5 seconds, stop the engine and determine the cause. Normal engine oil pressure is 345 kPa (3.45 bar) (50 psi) at rated full load speed (1800–2500 rpm) with oil at normal operating temperature of 115°C (240°F).
NOTE: On certain engines, the oil pressure and
coolant temperature gauges are replaced by indicator warning lights. The lights must be "OFF" when engine is running.
2. Watch coolant temperature gauge (B). Do not place engine under full load until it is properly warmed up. The normal engine coolant temperature range is 82°—94°C (180°—202°F).

NOTE: It is a good practice to operate the engine under
a lighter load and at lower speeds than normal for the first few minutes after start-up.

Normal Engine Operation

Observe engine coolant temperature and engine oil pressure. Temperatures and pressures will vary between engines and with changing operating conditions, temperatures, and loads.
Normal engine coolant operating temperature range is 82°—94°C (180°—202°F). If coolant temperature rises above 112°C (234°F), reduce load on engine. Unless temperature drops quickly, stop engine and determine cause before resuming operation.
Operate the engine under a lighter load and at slower than normal speed for first 15 minutes after start-up. DO NOT run engine at slow idle.
IMPORTANT: Should the engine die while operating
under load, immediately remove load and restart

the engine. Overheating of the turbocharger parts may occur when oil flow is stopped.
Stop engine immediately if there are any signs of part failure. Symptoms that may be early signs of engine problems are:
Sudden drop in oil pressure
Abnormal coolant temperatures
Unusual noise or vibration
Sudden loss of power
Excessive black exhaust
Excessive fuel consumption
Excessive oil consumption

Cold Weather Operation
CAUTION: Ether injector starting fluid is highly
flammable. DO NOT use starting fluid on engines equipped with air intake heaters.
DO NOT use starting fluid near fire, sparks, or flames. DO NOT incinerate or puncture a starting fluid container.
Engines may be equipped with intake air heaters, coolant heaters, or ether injectors as a cold weather starting aid.
Starting aids are required below 32°F (0°C). They will enhance starting performance above these temperatures and may be needed to start applications that have high parasitic loads during cranking and/or start acceleration to idle.
Using correct grade of oil (per engine and machine operator's manual) is critical to achieving adequate cold weather cranking speed.
Other cold weather starting aids are required at temperatures below -22°F (-30°C) or at altitudes above 1500 m (5000 ft).
TS1356 —UN—18MAR92
Handle Starting Fluid with Care
1. Follow steps 1—4 as listed under , then proceed as follows according to the instrument (gauge) panel on your engine.
2. Switch on the air intake heater for 30 seconds or activate ether injector by following suppliers instructions.
3. Follow remaining steps 5—8 as listed under earlier in this section.
Additional information on cold weather operation is available from your authorized servicing dealer.

Changing Engine Speed
To increase engine speed, turn throttle handle (A), if equipped, to the horizontal position and pull out until desired engine speed is obtained. Turn the handle in either direction to lock throttle position. The handle is pushed inward to decrease engine speed.
NOTE: On engines without handle, use throttle lever
to control engine speed.

Avoid Excessive Engine Idling

Prolonged idling may cause the engine coolant temperature to fall below its normal range. This, in turn, causes crankcase oil dilution, due to incomplete fuel combustion, and permits formation of gummy deposits on valves, pistons, and piston rings. It also promotes rapid accumulation of engine sludge and unburned fuel in the exhaust system.
Once an engine is warmed to normal operating temperatures, engine should be idled at slow idle speed.
Slow idle speed for this engine is 850 rpm at factory. If an engine will be idling for more than 5 minutes, stop and restart later.
NOTE: Generator set applications where the governor
is locked at a specified speed may not have a slow idle function. These engines will idle at no load governed speed (high idle).

Engine Operating Guidelines
Stopping the Engine
1. Disengage clutch (if equipped) controlling engine drivelines.
2. Move the throttle (A) to slow idle on standard (mechanical) governor engines.
IMPORTANT: Before stopping an engine that
has been operating at working load, idle engine at least 2 minutes at 1000–1200 rpm to cool hot engine parts.
For engines in generator set applications, where the governor is locked at a specified speed and no slow idle function is available, run engine for at least 2 minutes at fast idle and no load.
3. Turn key switch (B) to "OFF" position to stop the engine. Remove ignition key.
IMPORTANT: Make sure that exhaust stack cap (rain
cap) is installed when engine is not running. This will prevent water and dirt from entering engine.

Replenishing Supplemental Coolant Additives (SCAs) Between Coolant Changes
Radiator Coolant Check
IMPORTANT: Do not add supplemental coolant
additives when the cooling system is drained and refilled with John Deere COOL-GARD®
NOTE: If system is to be filled with coolant that does not
contain SCAs, the coolant must be precharged. Determine the total system capacity and premix with 3% John Deere Coolant Conditioner.
Through time and use, the concentration of coolant additives is gradually depleted during engine operation. Periodic replenishment of inhibitors is required, even when John Deere COOL-GARD® is used. The cooling system must be recharged with additional supplemental coolant additives available in the form of liquid coolant conditioner.
Maintaining the correct coolant conditioner concentration (SCAs) and freeze point is essential in your cooling system to protect against rust, liner pitting and corrosion, and freeze-ups due to incorrect coolant dilution.
John Deere LIQUID COOLANT CONDITIONER is recommended as a supplemental coolant additive in John Deere engines.
DO NOT mix one brand of SCA with a different brand.
Test the coolant solution every 500 hours or 12 months of operation using either John Deere coolant test strips or a COOLSCAN® analysis. If a COOLSCAN® analysis is not

RG6261 —UN—08DEC97
JT07298 Coolant/Battery Tester
available, recharge the system per instructions printed on label of John Deere Liquid Coolant Conditioner.
IMPORTANT: ALWAYS maintain coolant at correct
level and concentration. DO NOT operate engine without coolant even for a few minutes.
If frequent coolant makeup is required, the glycol concentration should be checked with JTO7298 Coolant/Battery Tester to ensure that the desired freeze point is maintained. Follow manufacturer's instructions provided with Coolant/Battery Tester.
Add the manufacturer's recommended concentration of supplemental coolant additive. DO NOT add more than the recommended amount.
The use of non-recommended supplemental coolant additives may result in additive drop-out and gelation of the coolant.
If other coolants are used, consult the coolant supplier and follow the manufacturer's recommendation for use of supplemental coolant additives.
See DIESEL ENGINE COOLANTS AND SUPPLEMENTAL ADDITIVE INFORMATION for proper mixing of coolant ingredients before adding to the cooling system.

Testing Diesel Engine Coolant
Maintaining adequate concentrations of glycol and inhibiting additives in the coolant is critical to protect the engine and cooling system against freezing, corrosion, and cylinder liner erosion and pitting.
Test the coolant solution at intervals of 12 months or less and whenever excessive coolant is lost through leaks or overheating.
Coolant Test Strips
Coolant test strips are available from your John Deere dealer. These test strips provide a simple, effective method to check the freeze point and additive levels of your engine coolant.
When Using John Deere COOL-GARD II
John Deere COOL-GARD II Premix™ , COOL-GARD II PG Premix and COOL-GARD II Concentrate are maintenance free coolants for up to six years or 6000 hours of operation, provided that the cooling system is topped off using only John Deere COOL-GARD II Premix or COOL-GARD II PG premix. Test the coolant condition annually with coolant test strips designed for use with John Deere COOL-GARD II coolants. If the test strip chart indicates that additive is required, add John Deere COOL-GARD II Coolant Extender as directed.
COOL-GARD is a trademark of Deere & Company
Add only the recommended concentration of John Deere COOL-GARD II Coolant Extender. DO NOT add more than the recommended amount.
When Using Nitrite-Containing Coolants
Compare the test strip results to the supplemental coolant additive (SCA) chart to determine the amount of inhibiting additives in your coolant and whether more John Deere Liquid Coolant Conditioner should be added.
Add only the recommended concentration of John Deere Liquid Coolant Conditioner. DO NOT add more than the recommended amount.
Coolant Analysis
For a more thorough evaluation of your coolant, perform a coolant analysis. The coolant analysis can provide critical data such as freezing point, antifreeze level, pH, alkalinity, nitrite content (cavitation control additive), molybdate content (rust inhibitor additive), silicate content, corrosion metals, and visual assessment.
Contact your John Deere dealer for more information on coolant analysis.

Pre-Start Cleaning Guide

IMPORTANT: Before cleaning machine, allow ample
time for hot surfaces to cool.
IMPORTANT: Do not direct high-pressure spray from
hose output directly at or close to electrical connections and sensors.
Rigorous cleaning as needed is recommended. Clean more frequently during heavy machine use, and when weather conditions are dry.
Check enclosed areas daily. Clean the engine and
other enclosed areas of equipment to remove debris and any buildup of oil and grease. Keep the engine and engine compartment free of combustible material. Check for debris buildup daily on and around intake
systems, exhaust systems, and intercooler piping systems. Verify that there are no holes or leaks in intake or exhaust systems. Do not allow debris to build up near hot exhaust components. Verify that hot exhaust components are cleaned as often as environmental conditions require. Inspect cooling system daily to determine whether
cooling system needs cleaning. Visible buildup of residue that blocks airflow may degrade machine performance and requires more frequent cleaning depending on environmental conditions.
Inspect difficult to observe areas daily as conditions
may require additional cleaning care to remove debris. Check for oil and fuel leaks daily. Replace or repair any
sources of leaks, including gaskets, seals, breather tubes, fittings, and fluid lines.
Maintenance and Service Reminders
Keep surfaces free of grease and oil.
Clean up after hydraulic and other fluid leaks.
Fuel Lines — Check for leaks, cracks, and kinks that
require service before use. Fuel Pumps — Check fittings, especially compression
ring couplings, for cracks and leaks. Fuel Injectors — Check pressure and return lines for
signs of leaks. When servicing fuel filter or draining water separator,
avoid fuel spills. Immediately clean up any fuel spill. Handle transmission and power steering fluids with
care. Immediately clean up any spills, especially around fill points. Check for transmission case venting system seepage,
transmission case leakage, power steering cylinder leakage, or power steering line leakage. Check for loose electrical connectors, damaged wiring,
corrosion, and poor connections.

Checking Air Compressor (If Equipped)
Air compressors are offered as options with John Deere OEM engines to provide compressed air to operate air-powered devices like vehicle air brakes.
Air compressors are engine-driven piston types. They are either air cooled or cooled with engine coolant. The compressors are lubricated with engine oil. The compressor runs continuously as gear or spline driven by the auxiliary drive of the engine but has “loaded” and “unloaded” operating modes. This is controlled by the vehicle's air system (refer to vehicle technical manual for complete air system checks and services).
See your John Deere engine distributor or servicing dealer for diagnostic and troubleshooting information. If diagnosis leads to an internal fault in the compressor, replace the complete compressor as a new or remanufactured unit.

Bleeding the Fuel System

CAUTION: Escaping fluid under pressure can
penetrate the skin causing serious injury. Relieve pressure before disconnecting fuel or other lines. Tighten all connections before applying pressure. Keep hands and body away from pinholes and nozzles which eject fluids under high pressure. Use a piece of cardboard or paper to search for leaks. Do not use your hand.
If ANY fluid is injected into the skin, it must be surgically removed within a few hours by a doctor familiar with this type injury or gangrene may result. Doctors unfamiliar with this type of injury may call the Deere & Company Medical Department in Moline, Illinois, or other knowledgeable medical source.
Bleed the fuel system anytime the fuel system has been opened up. This includes:
After fuel filter changes.
After injection pump or nozzle replacement.
Anytime fuel lines have been disconnected.
