(D). If not, add oil according to the oil recommendations chart (Figure 33).

CHANGE ENGINE OIL

Service Interval: 50 hours or once per season.

NOTE: Change engine oil while the engine is warm. Run the engine for a few minutes, then shut the engine off and allow it to cool from hot to warm.

1.Clean the area around the dip stick (C, Figure 34) and oil drain tube (A).

2.Remove the oil drain plug (A) from the end of the oil drain tube. Remove the dip stick (C). Allow ample time for complete drainage.

3.Reinstall the oil drain plug (A) and route the hose next to the engine.

4.Fill the crankcase with oil. See CHECK ENGINE OIL LEVEL above.

5.Start and run the engine at SLOW speed for 30 seconds. Stop the engine and recheck the oil level.

CHANGE ENGINE OIL & FILTER

Service Interval: 100 hours or once per season.

NOTE: Change engine oil while the engine is warm. Run the engine for a few minutes, then shut the engine off and allow it to cool from hot to warm.

1.Clean the area around the dip stick (C, Figure 34) and oil drain (A).

2.Remove the oil drain plug (A) and dip stick (C). Allow ample time for complete drainage.

3.Remove the oil filter (B). Discard the filter.

*CAUTION: Air cooled engines run hotter than automotive engines.

 

The use of non-synthetic multi-viscosity oils (5W-30, 10W-30, etc.)

 

in temperatures above 40º F (4ºC) will result in higher than normal

 

oil consumption. When using a multi-viscosity oil, check oil level

 

more frequently.

 

 

 

 

 

 

**CAUTION: SAE 30 oil, if used below 40º F (4ºC), will result in hard starting and possible engine bore damage due to inadequate lubrication.
