TO CHANGE ENGINE OIL (See Figs.  18 and 19)

ENGINE
LUBRICATION
Use only high quality detergent oil rated with API service 
classification SG-SL.  Select the oil’s SAE vis cos i ty grade 
according to your expected temperature.
NOTE:  Although multi-viscosity oils (5W-30, 10W-30, etc.) 
improve starting in cold weather, these multi-viscosity oils 
will result in increased oil consumption when used above 
40°F (4°C).  Check your engine oil level more frequently to 
avoid possible engine damage from running low on oil.
Change the oil after every 25 hours of operation or at 
least once a year if the tiller is not used for 25 hours in 
one year.
Check the crankcase oil level before starting the engine 
and after each five (5) hours of continuous use.  Add SAE 
30 motor oil or equivalent.  Tighten oil filler plug securely 
each time you check the oil level.
