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.

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.
Direct exposure to hazardous chemicals can cause
serious injury. Potentially hazardous chemicals used with
John Deere equipment include such items as lubricants,
coolants, paints, and adhesives.
A Material Safety Data Sheet (MSDS) provides specific
details on chemical products: physical and health hazards,
safety procedures, and emergency response techniques.
Check the MSDS before you start any job using a
hazardous chemical. That way you will know exactly what
the risks are and how to do the job safely. Then follow
procedures and recommended equipment.
(See your John Deere dealer for MSDS’s on chemical
products used with John Deere equipment.)

17. TM2254 (13OCT08)
Make certain all parts are reinstalled correctly if the
roll-over protective structure (ROPS) is loosened or
removed for any reason. Tighten mounting bolts to proper
torque.
The protection offered by ROPS will be impaired if ROPS
is subjected to structural damage, is involved in an
overturn incident, or is in any way altered by welding,
bending, drilling, or cutting. A damaged ROPS should be
replaced, not reused.
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.

18. TM2254 (13OCT08)
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.

Avoid possible injury or death from machinery runaway.
Do not start engine by shorting across starter terminals.
Machine will start in gear if normal circuitry is bypassed.
NEVER start engine while standing on ground. Start
engine only from operator’s seat, with transmission in
neutral or park.
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.

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.
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.
Entanglement in rotating driveline can cause serious injury
or death.
Keep tractor master shield and driveline shields in place
at all times. Make sure rotating shields turn freely.
Wear close fitting clothing. Stop the engine and be sure
PTO driveline is stopped before making adjustments,
connections, or cleaning out PTO driven equipment.
