Check the engine oil level. On first use there will be a small 

amount of oil left from factory testing but this will always require 
topping up.

This equipment is shipped with a low-oil sensor that will prevent 
startup if insufficient oil is available for operation. The low oil 
sensor will also shut down the engine when level is too low to 
protect the engine.

side facing out).
