3. OPERATION
WARNING
3.2 DIESEL FUEL
Do not mix oil with fuel. The engine has a separate oil
reservoir in the crankcase. Diesel fuel blend meeting
ASTM D915 or EN590 and a premium diesel fuel
conditioner is recommended.
FUEL IS BOTH TOXIC AND FLAMMABLE. DO
NOT SMOKE WHILE WORKING WITH FUEL.
DO NOT USE NEAR OPEN FLAME. ALWAYS
STOP ENGINE BEFORE REFUELING. CLEAN UP
SPILLED FUEL BEFORE STARTING. AVOID
FIRES BY KEEPING ENGINE CLEAN OF
ACCUMULATED GREASE AND DEBRIS.
START, STORE, AND REFUEL ON LEVEL
GROUND TO PREVENT PERSONAL INJURY. DO
NOT RUN UNIT IN AN ENCLOSED, NON-
VENTILATED AREA. AVOID PROLONGED
BREATHING OF VAPORS AND SKIN CONTACT.
SERIOUS ILLNESS OR LOSS OF LIFE COULD
RESULT.
KEEP THE VENT HOLE IN FUEL TANK CAP
OPEN. IF VENT HOLE IS PLUGGED, PRESSURE
MAY BUILD UP IN TANK, CAUSING
DANGEROUS SPRAYING OF FUEL WHEN TANK
CAP IS REMOVED. A VACUUM MAY ALSO BE
CREATED DURING OPERATION, WHICH
COULD STOP FUEL FLOW. DIESEL FUEL IS
MANDATORY FOR USE IN THIS ENGINE.
ALWAYS USE CLEAN FUEL. LOW QUALITY OR
CONTAMINATED FUEL WILL DAMAGE FUEL
INJECTION COMPONENTS.
DIESEL FUEL STORED IN GALVANIZED
CONTAINERS REACTS CHEMICALLY WITH
THE ZINC COATING ON THE CONTAINER. THE
CHEMICAL REACTION CREATES POWDERY
FLAKES OF ZINC SULFIDE. IF WATER IS
PRESENT IN THE FUEL, A ZINC HYDROXIDE
GEL WILL FORM.
3.3 ENGINE BREAK-IN
IMPORTANT Read Engine Manual for break-in
requirements. 1
st
100 hours John Deere break-in oil
only (TY 22041). Do not add oil until level is in the

hours. Use SAE 15W-40 API CG-4 or API CF-4. Refer
to Engine Manual for additional oil types and
recommendations. Do not mix different brands or
types of oil. Mixing oils can degrade lubrication
performance.

3.6 HYDRAULIC OIL, FILTER, BREATHER
PRESSURIZED RELEASE OF FLUIDS FROM
HYDRAULIC SYSTEM CAN CAUSE SERIOUS
BURNS. SHUT OFF ENGINE. ONLY REMOVE
BREATHER CAP WHEN COOL ENOUGH TO
TOUCH WITH BARE HANDS. SLOWLY LOOSEN
