Choose the recommended viscosity based on the type of start (recoil, crank-
handle or electric) and on the engine temperature at which the engine will be
operated.
CAUTION
Engine damage from unsuitable engine oil.
Using engine oil that does not meet the above specifications
considerably shortens the engine service life.
