MAINTENANCE SCHEDULE
CHANGING ENGINE OIL:
Change oil after the first 20 hours of operation. Thereafter it
should be changed every 100 hours.
1. Drain oil by removing the drain plug and the oil filler cap
while the engine is warm. (Fig. 16)
2. Reinstall the drain plug and fill the engine with oil until it
reaches the upper level on the oil filler cap.
NOTE: John Deere PLUS-4 ® oil is the preferred oil to use. If
John Deere PLUS-4 ® oil is not available, use 4-stroke
automotive detergent oil of API service class SE or
higher grade (SG, SH or SJ is recommended). If
contaminated or deteriorated oil is used or the quantity
of the engine oil is not sufficient, the engine damage
will result and its life will be greatly shortened.
3. Dispose of used oil according to local zoning or
environmental regulations.
SERVICING THE AIR CLEANER:
Maintaining an air cleaner in proper condition is very
important. Dirt induced through improperly installed,
improperly serviced or inadequate elements damages and
wears out engines. Always keep the element clean.
1. Unhook the cover and remove the cleaner element. (Fig.
17)
2. Urethane foam: Wash the element with fresh water.
Squeeze out the water then dry the element. (Do not
twist.)
CLEANING AND GAPPING SPARK PLUG:
If the plug is contaminated with carbon, remove the carbon
using a plug cleaner or wire brush. (Fig. 18)
Adjust the electrode gap to 0.6 to 0.7 mm (0.024 to
0.028 in). (Fig. 19)
