CARB Non-road Emissions Control Warranty Statement—Compression Ignition
Emissions Control Warranty Statement 2019 through 2021
DXLOGOV1 —UN—28APR09
CALIFORNIA EMISSIONS CONTROL WARRANTY STATEMENT
YOUR WARRANTY RIGHTS AND OBLIGATIONS
To determine if the John Deere engine qualifies for the additional warranties set forth below, look for the “Emission Control Information” label located
on the engine. If the engine is operated in the United States or Canada and the engine label states: “This engine complies with US EPA regulations
for nonroad and stationary diesel engines”, or “This engine complies with US EPA regulations for stationary emergency diesel engines”, refer to
the “U.S. and Canada Emission Control Warranty Statement.” If the engine is operated in California, and the engine label states: “This engine
complies with US EPA and CARB regulations for nonroad diesel engines” also refer to the “California Emissions Control Warranty Statement.”
Warranties stated on this certificate refer only to emissions-related parts and components of your engine. The complete engine warranty, less
emission-related parts and components, is provided separately. If you have any questions about your warranty rights and responsibilities,
you should contact John Deere at 1-319-292-5400.
CALIFORNIA EMISSIONS CONTROL WARRANTY STATEMENT:
The California Air Resources Board (CARB) is pleased to explain the emission-control system warranty on 2019 through 2021 off-road diesel
engines. In California, new off-road engines must be designed, built and equipped to meet the State’s stringent anti-smog standards. John Deere
must warrant the emission control system on your engine for the periods of time listed below provided there has been no abuse, neglect or
improper maintenance of your engine.
Your emission control system may include parts such as the fuel injection system and the air induction system. Also included may be hoses, belts,
connectors and other emission-related assemblies.
John Deere warrants to the ultimate purchaser and each subsequent purchaser that this off-road diesel engine was designed, built, and equipped
so as to conform at the time of sale with all applicable regulations adopted by CARB and is free from defects in materials and workmanship which
would cause the failure of a warranted part to be identical in all material respects to the part as described in John Deere's application for certification
for a period of five years from the date the engine is delivered to an ultimate purchaser or 3,000 hours of operation, whichever occurs first for all
engines rated at 19 kW and greater. In the absence of a device to measure hours of use, the engine shall be warranted for a period of five years.
EMISSIONS WARRANTY EXCLUSIONS:
John Deere may deny warranty claims for failures caused by the use of an add-on or modified part which has not been exempted by the CARB. A
modified part is an aftermarket part intended to replace an original emission-related part which is not functionally identical in all respects and
which in any way affects emissions. An add-on part is any aftermarket part which is not a modified part or a replacement part.
In no event will John Deere, any authorized engine distributor, dealer, or repair facility, or any company affiliated with John Deere be liable
for incidental or consequential damage.

Safety—General Precautions
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 voltmeter or hydrometer.
TS204 —UN—15APR13
Do not charge a frozen battery; it may explode. Warm
battery to 16°C (60°F).
Keep battery electrolyte levels properly maintained.
Battery Explosions
TX,PREVENT,BATT -19-24FEB20-1/1
Clean Debris from Machine
Keep engine compartment, radiator, batteries, hydraulic
lines, exhaust components, fuel tank, and operator's
station clean and free of debris.
Clean any oil spills or fuel spills on machine surfaces.
T6669AG —UN—15APR13
Temperature in engine compartment could go up
immediately after engine is stopped. BE ON GUARD
FOR FIRES DURING THIS PERIOD.
Open access door(s) to cool the engine faster, and clean
engine compartment.
TX,DEBRIS -19-20JAN11-1/1
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.)

Safety—Operating Precautions
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.
