3. Safety - 1
SAFETY
Safety
Recognize Safety Information
MIF
This is the safety-alert symbol. When you see this symbol
on your machine or in this manual, be alert to the potential
for personal injury.
Follow recommended precautions and safe servicing
practices.
Understand Signal Words
A signal word - DANGER, WARNING, or CAUTION - is
used with the safety-alert symbol. DANGER identifies the
most serious hazards.
DANGER or WARNING safety signs are located near
specific hazards. General precautions are listed on
CAUTION safety signs. CAUTION also calls attention to
safety messages in this manual.
Replace Safety Signs
MIF
Replace missing or damaged safety signs. See the
machine operator’s manual for correct safety sign
placement.
Be Prepared for Emergencies
MIF
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.
MIF
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.
4. Safety - 2
SAFETY
Prevent Battery Explosions
MIF
• 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 voltmeter or hydrometer.
• Do not charge a frozen battery; it may explode. Warm
battery to 16°C (60°F).
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 acid burns by:
a. Filling batteries in a well-ventilated area.
b. Wearing eye protection and rubber gloves.
c. Avoiding breathing fumes when electrolyte is added.
d. Avoiding spilling or dripping electrolyte.
e. Using proper jump start procedure.
• If you spill acid on yourself:
a. Flush your skin with water.
b. Apply baking soda or lime to help neutralize the acid.
c. Flush your eyes with water for 10-15 minutes.
d. Get medical attention immediately.
• If acid is swallowed:
a. Drink large amounts of water or milk.
b. Then drink milk of magnesia, beaten eggs, or
vegetable oil.
c. Get medical attention immediately.
Avoid High-Pressure Fluids
MIF
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.
Information may be obtained in the United States and
Canada only by calling 1-800-822-8262.
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 be accidentally cut when
heat goes beyond the immediate flame area.
5. Safety - 3
SAFETY
Wear Protective Clothing
MIF
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.
Service Machines Safely
MIF
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.
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.

injury or machine damage. Follow recommended
procedure for removal and installation of components in the
manual.
6. Safety - 4
SAFETY
Work in Clean Area
Before starting a job:
1. Clean work area and machine.
2. Make sure you have all necessary tools to do your job.
3. Have the right parts on hand.
4. Read all instructions thoroughly; do not attempt
shortcuts.
Using High-Pressure Washers
Directing pressurized water at electronic/electrical
components or connectors, bearings, hydraulic seals, fuel
injection pumps or other sensitive parts and components
may cause product malfunctions. Reduce pressure and
spray at a 45 to 90 degree angle.
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.
Work in Ventilated Area
MIF
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.
WARNING: California Proposition 65 Warning
Gasoline engine exhaust from this product contains
chemicals known to the State of California to cause cancer,
birth defects, or other reproductive harm.
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. Do all work outside or in a well-
ventilated area. Dispose of paint and solvent properly.
Remove paint before welding or heating. 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.
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.
Service Tires Safely
MIF
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
7. Safety - 5
SAFETY
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.
Avoid Injury from Rotating Blades, Augers,
and PTO Shafts
MIF
Keep hands and feet away while machine is running. Shut
off power to service, lubricate, or remove mower blades,
augers, or PTO shafts.
Handling Fuel Safely
Fuel and fuel vapors are highly flammable:
MIF
• Do not refuel machine while you smoke, when machine
is near an open flame or sparks, or when engine is running.
Stop engine and allow to cool before filling.
• Never remove the fuel cap or add fuel with the engine
running.
• Never fill fuel tank or drain fuel from a machine in an
enclosed area. Fill fuel tank outdoors.
• Prevent fires. Clean up spilled fuel immediately.
• Do not store machine with fuel in tank in a building
where fumes may reach an open flame or spark.
• Prevent fire and explosion caused by static electric
discharge. Use only non-metal, portable fuel containers
approved by the Underwriter’s Laboratory (U.L.) or the
American Society for Testing & Materials (ASTM). If using a
funnel, make sure it is plastic and has no screen or filter.
MIF
• Static electric discharge can ignite gasoline vapors in an
ungrounded fuel container. Remove the fuel container from
the bed of a vehicle or the trunk of a car and place on the
ground away from the vehicle before filling. Keep nozzle in
contact with container opening while filling.
• When practical, remove equipment from trailers or truck
beds and refuel them on the ground. If this is not possible,
use a portable, plastic fuel container to refuel equipment on
a truck bed or trailer.
• For gasoline engines, do not use gas with methanol.
Methanol is harmful to your health and to the environment.
8. Safety - 6
SAFETY
Handle Chemical Products Safely
MIF
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.
Dispose of Waste Properly
Improperly disposing of waste can threaten the
environment and ecology. Potentially harmful waste used
with John Deere equipment includes 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. Inquire on the
proper way to recycle or dispose of waste from your local
environmental or recycling center, or from your John Deere
dealer.
