Environmental Considerations 

Altitude 

If the engine is being used in altitudes at or above 1500m (approximately 5000’), adjustments to the 

carburettor may be required. This is because there is less oxygen in the air as altitude increases, which 

effectively “enriches” the ratio of fuel to air going into the engine and the higher the altitude, the richer 

the fuel mixture becomes. If the engine is being permanently operated at high altitude, it is 

recommended to have an authorized service centre make the necessary carburettor adjustments. If the 

engine is used occasionally at altitude (not extreme altitudes), no adjustments should be required, 

however, a slight decrease in engine performance can be 

expected. 

Temperature 

If the engine is being used in extremely cold or hot 

environments; for example, desert or snow conditions, the type 

of engine oil may need to be changed to suit environmental 

temperatures. Oil thickens as the temperature decreases and 

thins as temperature increases, which means that if the engine oil is not suited to the temperature its 

ability to properly lubricate the engine may be affected. Use the following chart to determine the correct 

engine oil:
