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.

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.

Safety
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).
HX00517,0002245 –19–02OCT00–1/1
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.

Handle Starting Fluid Safely
Starting fluid is highly flammable.
Keep all sparks and flame away when using it. Keep
starting fluid away from batteries and cables.
To prevent accidental discharge when storing the
pressurized can, keep the cap on the container, and store
in a cool, protected location.
Do not incinerate or puncture a starting fluid container.

TM1902 (01JUN03) 210-05-2 9650 STS and 9750 STS Combines
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.

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.

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.

Support Machine Properly
Always lower the attachment or implement to the ground
before you work on the machine. If you must work on a
lifted machine or attachment, securely support the
machine or attachment.
Do not support the machine on cinder blocks, hollow tiles,
or props that may crumble under continuous load. Do not
work under a machine that is supported solely by a jack.
Follow recommended procedures in this manual.
HX00517,000224C –19–02OCT00–1/1
Service Machines Safely
Tie long hair behind your head. Do not wear a necktie,
scarf, loose clothing, or necklace when you work near
machine tools or moving parts. If these items were to get
caught, severe injury could result.
Remove rings and other jewelry to prevent electrical
shorts and entanglement in moving parts.
HX00517,000224D –19–02OCT00–1/1
Work In Ventilated Area
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 exhaust pipe extension, open the doors
and get outside air into the area

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 operators manual for correct safety sign
placement.
HX00517,0002250 –19–02OCT00–1/1
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.
HX00517,0002251 –19–02OCT00–1/1
Protect Against Noise
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.

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.
HX00517,0002253 –19–02OCT00–1/1
Work in Clean Area

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

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.
