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.

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
operation and tests. Repair sections tell how to repair
the components. Operation and tests 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, service parts kits,
specifications, wear tolerances, and torque values.

Technical Manuals are concise guides for specific
machines. They are on-the-job guides containing only
the vital information needed for diagnosis, analysis,
testing, and repair.

Fundamental service information is available from
other sources covering basic theory of operation,
fundamentals of troubleshooting, general maintenance,
and basic type of failures and their causes.

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.

TM1902 (01JUN03) 210-05-3 9650 STS and 9750 STS Combines
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.








HX00517,000224A –19–02OCT00–1/1
Park Machine Safely

Before working on the machine:

• Lower all equipment to the ground.
• Stop the engine and remove the key.
• Disconnect the battery ground strap.
• Hang a "DO NOT OPERATE" tag in operator station.

Service Tires Safely

Explosive separation of a tire and rim parts can cause
serious injury or death.

Do not attempt to mount a tire unless you have the proper
equipment and experience to perform the job.

Always maintain the correct tire pressure. Do not inflate
the tires above the recommended pressure. Never weld or
heat a wheel and tire assembly. The heat can cause an
increase in air pressure resulting in a tire explosion.
Welding can structurally weaken or deform the wheel.

When inflating tires, use a clip-on chuck and extension
hose long enough to allow you to stand to one side and
NOT in front of or over the tire assembly. Use a safety
cage if available.

Check wheels for low pressure, cuts, bubbles, damaged
rims or missing lug bolts and nuts.

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.

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.

Each combine has identification plates similar to the one
shown. The letters and numbers stamped on these plates
identify a component or assembly. ALL of these
characters are needed when ordering parts or identifying
a combine or component for any John Deere product
support program. Also, they are needed for law
enforcement to trace your combine if it is ever stolen.
