7.6 Engine Oil
Checking oil
Check engine oil daily before starting engine.
• Do not operate engine if oil level is below ADD mark on dipstick.
Always keep oil level within the crosshatch pattern or “full” mark on
dipstick.
• Change oil after first 100 hours of operation and every 250 hours
thereafter. Refer to the engine manufacturer’s Operator’s Manual for
lubrication specifications.
Break-in Service
• This engine is factory-filled with John Deere Engine Break-in Oil.
• Operate the engine at heavy loads with minimal idling during the
break-in period.
• Do not exceed 100 hours of operation with break-in oil.
• If the engine has significant operating time at light load, or more oil is
required in the first 100 hour period, a longer break-in period may be
required. In these situations, an additional 100 hour break-in period
is recommended using a new change of John Deere Engine Break-In
Oil and a new John Deere oil filter.
NOTICE:
Do not add more oil until the oil level is BELOW the ADD mark
on the dipstick. John Deere Engine Break-In Oil (TY22041) should be
used to make up any oil consumed during the break-in period.
• During the first 20 hours, avoid prolonged periods of no load or
sustained maximum load operation. If engine is to run for longer than
5 minutes without a load, shut unit down.
• After the first 100 hours, change engine oil and replace engine oil
filter. Fill crankcase with seasonal viscosity grade oil.
WARNING
Burn hazard. Engine, engine oil, muffler, and exhaust pipes become extremely hot
during operation.
f Stop the engine and allow the machine to cool before checking the oil or replac-
ing the engine oil or oil filter cartridge.
WARNING
Most used oil contains small amounts of materials that can cause cancer and other
health problems if inhaled, ingested, or left in contact with skin for prolonged
periods of time.
f Take steps to avoid inhaling or ingesting used engine oil.
f Wash skin thoroughly after exposure to used engine oil.
