0 30 32 40
TEMPERATURE RANGE ANTICIPATED BEFORE h_EXT OIL C_AhlG_
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°1:. Check your
engine oil level more frequently to avoid
possible engine damage from running
low on oil.
Change the oil 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 oil level before
starting the engine and after each five (5)
hours of continuous use. Tighten oil plug
securely each time you check the oil
level.
