NOTE: Although
multi-viscosity
oils
(5W30, 10W30 etc.)improve
starting in
cold weather, these multi-viscosity
oils will
result in increased oil consumption
when
used above 32°F. Check your engine oil
level more frequently to avoid possible
engine damage from running low on oil.
Change the oi! after every 25 hours of
operation or at least once a year if the unit
is not used for 25 hours in one year.
Check the crankcase oi! level before
starting the engine and after each five (5)
hours of continuous
use. Tighten oil plug
