cold weather, these muki-viscosity oils will
result in increased oil consumption when
used above 32°R Check your engine oil
level more frequently to avoid possible

operation or at least once a year if the unit
is not used for 25 hours in one year.

starting the engine and after each five (5)
hours of continuous use. Tighten oil plug
securely each time you check the oil level.
