Lubricating the Engine
Checking oil
Check engine oil daily before starting engine.
WARNING
Burn hazard. Engine, engine oil, muffler, and exhaust pipes become extremely hot
during operation.
Stop the engine and allow the machine to cool before checking the oil or replac-
ing the engine oil or oil filter cartridge.
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
This engine is factory-filled with John Deere Engine Break-in Oil.
Service
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
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 peri-
ods of time.
Take steps to avoid inhaling or ingesting used engine oil.
Wash skin thoroughly after exposure to used engine oil.
