READ THIS MANUAL carefully to learn how to operate
and service your engine correctly. Failure to do so
could result in personal injury or equipment damage.
THIS MANUAL SHOULD BE CONSIDERED a
permanent part of your engine and should remain with
the engine when you sell it.
MEASUREMENTS IN THIS MANUAL are given in both
metric and customary U.S. unit equivalents. Use only
correct replacement parts and fasteners. Metric and
inch fasteners may require a specific metric or inch
wrench.
WRITE ENGINE SERIAL NUMBERS and option codes
in the spaces indicated in the Record Keeping Section.
Accurately record all the numbers. Your dealer also
needs these numbers when you order parts. File the
identification numbers in a secure place off the engine.
SETTING FUEL DELIVERY beyond published factory
specifications or otherwise overpowering will result in
loss of warranty protection for this engine.
Emission certified for United States as EPA Tier 2 and for European
Union as Stage II.

Engine Option Codes
A—Engine Base Code
In addition to the serial number plate, OEM engines
have an engine option code label affixed to the rocker
arm cover. These codes indicate which of the engine
options were installed on your engine at the factory.
When in need of parts or service, furnish your
authorized servicing dealer or engine distributor with
these numbers.
RG11946 –UN–06NOV01
The engine option code label includes an engine base
code (A). This base code must also be recorded along
with the option codes.
The first two digits of each code identify a specific
group, such as alternators. The last two digits of each
code identify one specific option provided on your
engine, such as a 12-volt, 55-amp alternator.
NOTE: These option codes are based on the latest
information available at the time of publication.
The right is reserved to make changes at any
time without notice.
If an engine is ordered without a particular component,
the last two digits of that functional group option code
will be 99, 00, or XX. The list on the next page shows
only the first two digits of the code numbers. For future
reference such as ordering repair parts, it is important
to have these code numbers available. To ensure this
availability, enter the third and fourth digits shown on

Avoid High-Pressure Fluids
Escaping fluid under pressure can penetrate the skin
causing serious injury.
Avoid the hazard by relieving pressure before
disconnecting hydraulic or other lines. Tighten all
connections before applying pressure.
Search for leaks with a piece of cardboard. Protect hands
and body from high pressure fluids.
If an accident occurs, see a doctor immediately. Any fluid
injected into the skin must be surgically removed within a
few hours or gangrene may result. Doctors unfamiliar with
this type of injury should reference a knowledgeable
medical source. Such information is available from Deere
& Company Medical Department in Moline, Illinois, U.S.A.
X9811 –UN–23AUG88
Avoid Heating Near Pressurized Fluid Lines
Flammable spray can be generated by heating near
pressurized fluid lines, resulting in severe burns to
yourself and bystanders. Do not heat by welding,
soldering, or using a torch near pressurized fluid lines or
other flammable materials. Pressurized lines can
accidentally burst when heat goes beyond the immediate
flame area.
Do Not Open High-Pressure Fuel System
High-pressure fluid remaining in fuel lines can cause
serious injury. Do not disconnect or attempt repair of fuel
lines, sensors, or any other components between the
high-pressure fuel pump and nozzles on engines with
High Pressure Common Rail (HPCR) fuel system.

Remove Paint Before Welding or Heating
Avoid potentially toxic fumes and dust.
Hazardous fumes can be generated when paint is heated
by welding, soldering, or using a torch.
Remove paint before heating:
• Remove paint a minimum of 100 mm (4 in.) from area
to be affected by heating. If paint cannot be removed,
wear an approved respirator before heating or welding.
• If you sand or grind paint, avoid breathing the dust.
Wear an approved respirator.
• If you use solvent or paint stripper, remove stripper with
soap and water before welding. Remove solvent or
paint stripper containers and other flammable material
from area. Allow fumes to disperse at least 15 minutes
before welding or heating.
Do not use a chlorinated solvent in areas where welding
will take place.
TS220 –UN–23AUG88
Do all work in an area that is well ventilated to carry toxic
fumes and dust away.
Dispose of paint and solvent properly.
Service Cooling System Safely
Explosive release of fluids from pressurized cooling
system can cause serious burns.
Shut off engine. Only remove filler cap when cool enough
to touch with bare hands. Slowly loosen cap to first stop
to relieve pressure before removing completely.

Safety
Avoid Harmful Asbestos Dust
Avoid breathing dust that may be generated when
handling components containing asbestos fibers. Inhaled
asbestos fibers may cause lung cancer.
Components in products that may contain asbestos fibers
are brake pads, brake band and lining assemblies, clutch
plates, and some gaskets. The asbestos used in these
components is usually found in a resin or sealed in some
way. Normal handling is not hazardous as long as
airborne dust containing asbestos is not generated.
Avoid creating dust. Never use compressed air for
cleaning. Avoid brushing or grinding material containing
asbestos. When servicing, wear an approved respirator. A
special vacuum cleaner is recommended to clean
asbestos. If not available, apply a mist of oil or water on
the material containing asbestos.
Keep bystanders away from the area.

Prevent Battery Explosions
Keep sparks, lighted matches, and open flame away from
the top of battery. Battery gas can explode.
Never check battery charge by placing a metal object
across the posts. Use a volt-meter or hydrometer.
Do not charge a frozen battery; it may explode. Warm
battery to 16°C (60°F).
Use Proper Lifting Equipment
Lifting heavy components incorrectly can cause severe
injury or machine damage.
Follow recommended procedure for removal and
installation of components in the manual.

Handling Batteries Safely
CAUTION: Battery gas can explode. Keep
sparks and flames away from batteries. Use a
flashlight to check battery electrolyte level.
Never check battery charge by placing a metal
object across the posts. Use a voltmeter or
hydrometer.
Safety
Always remove grounded (—) battery clamp
first and replace it last.
CAUTION: Sulfuric acid in battery electrolyte is
poisonous. It is strong enough to burn skin, eat
holes in clothing, and cause blindness if
splashed into eyes.
Avoid the hazard by:
1. Filling batteries in a well-ventilated area.
2. Wearing eye protection and rubber gloves.
3. Avoiding breathing fumes when electrolyte is
added.
4. Avoiding spilling or dripping electrolyte.
5. Using proper jump start procedure.
If you spill acid on yourself:
1. Flush your skin with water.
2. Apply baking soda or lime to help neutralize
the acid.
3. Flush your eyes with water for 15—30
minutes. Get medical attention immediately.

Safety
Protect Against High Pressure Spray
Spray from high pressure nozzles can penetrate the skin
and cause serious injury. Keep spray from contacting
hands or body.
If an accident occurs, see a doctor immediately. Any high
pressure spray injected into the skin must be surgically
removed within a few hours or gangrene may result.
Doctors unfamiliar with this type of injury should reference
a knowledgeable medical source. Such information is
available from Deere & Company Medical Department in
Moline, Illinois, U.S.A.
Dispose of Waste Properly
TS1343 –UN–18MAR92
DX,SPRAY –19–16APR92–1/1
Improperly disposing of waste can threaten the
environment and ecology. Potentially harmful waste used
with John Deere equipment include such items as oil, fuel,
coolant, brake fluid, filters, and batteries.
Use leakproof containers when draining fluids. Do not use
food or beverage containers that may mislead someone
into drinking from them.
Do not pour waste onto the ground, down a drain, or into
any water source.
Air conditioning refrigerants escaping into the air can
damage the Earth’s atmosphere. Government regulations
may require a certified air conditioning service center to
recover and recycle used air conditioning refrigerants.
Inquire on the proper way to recycle or dispose of waste
from your local environmental or recycling center, or from
your John Deere dealer.
