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

Determine temperature range expected before oil change.  
All oil must  meet API service classifi cation SG-SL
•      Be sure tiller is on level surface.
•      Oil will drain more freely when warm.
•      Use a funnel to prevent oil spill on tiller, and catch oil 

in a suitable con tain er.

•      Remove drain plug.
•      Tip tiller forward to drain oil.
•      After oil has drained completely, replace oil drain plug 

and tighten securely.

ENGINE

LUBRICATION

Use only high quality detergent oil rated with API service 
classifi cation 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 
32°F (0°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 fi ve (5) hours of continuous use.  Add SAE 
30 motor oil or equivalent.  Tighten oil fi ller plug securely 
each time you check the oil level.
