FOREWORD
This manual is written for an experienced technician.
Essential tools required in performing certain service
work are identified in this manual and are
recommended for use.
Live with safety: Read the safety messages in the
introduction of this manual and the cautions
presented throughout the text of the manual.
N This is the safety-alert symbol. When you see
this symbol on the machine or in this manual,
be alert to the potential for personal injury.
Technical manuals are divided in two parts: repair
and diagnostics. Repair sections tell how to repair the
components. Diagnostic sections help you identify the
majority of routine failures quickly.
Information is organized in groups for the various
components requiring service instruction. At the
beginning of each group are summary listings of all
applicable essential tools, service equipment and
tools, other materials needed to do the job and
service parts kits.
Section 10, Group 15—Specifications consist of all
applicable specifications, near tolerances and specific
torque values for various components on each
individual engine.
Binders, binder labels, and tab sets can be ordered
by John Deere dealers direct from the John Deere
Distribution Service Center.
This manual is part of a total product support
program.

Fundamentals of Service (FOS) Manuals cover basic
theory of operation, fundamentals of troubleshooting,
general maintenance, and basic type of failures and
their causes. FOS Manuals are for training new
personnel and for reference by experienced
technicians.
Technical Manuals are concise guides for specific
machines. Technical manuals are on-the-job guides
containing only the vital information needed for
diagnosis, analysis, testing, and repair.
Component Technical Manuals are concise service
guides for specific components. Component technical
manuals are written as stand-alone manuals covering
multiple machine applications.

HANDLE FLUIDS SAFELY—AVOID FIRES
When you work around fuel, do not smoke or work near
heaters or other fire hazards.
Store flammable fluids away from fire hazards. Do not
incinerate or puncture pressurized containers.
Make sure machine is clean of trash, grease, and debris.
Do not store oily rags; they can ignite and burn
spontaneously.
TS227
-UN-23AUG88
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).
TS204
-UN-23AUG88
PREPARE FOR EMERGENCIES
Be prepared if a fire starts.
Keep a first aid kit and fire extinguisher handy.
Keep emergency numbers for doctors, ambulance
service, hospital, and fire department near your
telephone.

PREVENT ACID BURNS
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. Use 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.
If acid is swallowed:
1. Do not induce vomiting.
2. Drink large amounts of water or milk, but do not
exceed 2 L (2 quarts).
3. Get medical attention immediately.
TS203
-UN-23AUG88
WEAR PROTECTIVE CLOTHING
Wear close fitting clothing and safety equipment
appropriate to the job.
Prolonged exposure to loud noise can cause impairment
or loss of hearing.
Wear a suitable hearing protective device such as
earmuffs or earplugs to protect against objectionable or
uncomfortable loud noises.
Operating equipment safely requires the full attention of
the operator. Do not wear radio or music headphones
while operating machine.

WORK IN CLEAN AREA
Before starting a job:
• Clean work area and machine.
• Make sure you have all necessary tools to do your job.
• Have the right parts on hand.
• Read all instructions thoroughly; do not attempt
shortcuts.

WORK IN VENTILATED AREA
WARNING
California Proposition 65 Warning: Gasoline engine
exhaust from this product contains chemicals known
to to State of California to cause cancer, birth
defects, or other reproductive harm.
Engine exhaust fumes can cause sickness or death, If it
is necessary to run an engine in an enclosed area,
remove the exhaust fumes from the area with an
exhaust pipe extension.
If you do not have an exhaust pipe extension, open the
doors and get outside air into the area.
TS220
-UN-23AUG88
ILLUMINATE WORK AREA SAFELY
Illuminate your work area adequately but safely. Use a
portable safety light for working inside or under the
machine. Make sure the bulb is enclosed by a wire
cage. The hot filament of an accidentally broken bulb
can ignite spilled fuel or oil.

REPLACE SAFETY SIGNS
Replace missing or damaged safety signs. See the
machine operator’s manual for correct safety sign
placement.
TS201
-UN-23AUG88
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.

USE PROPER TOOLS
Use tools appropriate to the work. Makeshift tools and
procedures can create safety hazards.
Use power tools only to loosen threaded parts and
fasteners.
For loosening and tightening hardware, use the correct
size tools. DO NOT use U.S. measurement tools on
metric fasteners. Avoid bodily injury caused by slipping
wrenches.
Use only service parts meeting John Deere
specifications.
TS779
-UN-08NOV89
DISPOSE OF WASTE PROPERLY
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.
