Safety
Practice Safe Maintenance
Understand service procedure before doing work. Keep
area clean and dry.
Never lubricate, service, or adjust machine while it is
moving. Keep hands, feet, and clothing away from
power-driven parts. Disengage all power and operate
controls to relieve pressure. Lower equipment to the
ground. Stop the engine. Remove the key. Allow machine
to cool.
Securely support any machine elements that must be
raised for service work.
Keep all parts in good condition and properly installed.
Fix damage immediately. Replace worn or broken parts.
Remove any buildup of grease, oil, or debris.
On self-propelled equipment, disconnect battery ground
cable (-) before making adjustments on electrical systems
or welding on machine.
On towed implements, disconnect wiring harnesses from
tractor before servicing electrical system components or
TS218 --UN--23AUG88
welding on machine.
Falling while cleaning or working at height can cause
serious injury. Use a ladder or platform to easily reach
each location. Use sturdy and secure footholds and
handholds.
DX,SERV -19-28FEB17-1/1
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.
TS779 --UN--08NOV89
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.

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.
TS227 --UN--15APR13
Make sure machine is clean of trash, grease, and debris.
Do not store oily rags; they can ignite and burn
spontaneously.
DX,FLAME -19-29SEP98-1/1
Handle Chemical Products Safely
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.
TS1132 --UN--15APR13
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.)

Drain Gasoline When Storing Machine
Gasoline stored in fuel tank can explode.
Never store equipment with gasoline in the tank inside a
building where fumes may reach an open flame or spark.
Always drain gasoline from fuel tank and carburetor bowl

Safety
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

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.

Handling Batteries Safely
Battery gas can explode. Keep sparks and flames away
from batteries. Use a flashlight to check battery electrolyte
level.
Never check battery charge by placing a metal object
across the posts. Use a voltmeter or hydrometer.

Always remove grounded (-) battery clamp first and
replace grounded clamp last.
Sulfuric acid in battery electrolyte is poisonous and strong
enough to burn skin, eat holes in clothing, and cause
blindness if splashed into eyes.
Avoid hazards by:
· Filling batteries in a well-ventilated area
· Wearing eye protection and rubber gloves
· Avoiding use of air pressure to clean batteries
· Avoiding breathing fumes when electrolyte is added
· Avoiding spilling or dripping electrolyte
· Using correct battery booster or charger procedure.
If acid is spilled on skin or in eyes:
1. Flush skin with water.
2. Apply baking soda or lime to help neutralize the acid.
3. Flush eyes with water for 15--30 minutes. Get
medical attention immediately.
If acid is swallowed:
1. Do not induce vomiting.

before you work on the machine. If the work requires
that the machine or attachment be lifted, provide secure
support for them. If left in a raised position, hydraulically
supported devices can settle or leak down.
TS229 --UN--23AUG88
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.
When implements or attachments are used with a
machine, always follow safety precautions listed in the
implement or attachment operator's manual.

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.
