the engine and after each five (5) hours of continuous
use.,Add S.,A.E. 5W30 motor oil as needed. Tighten fill
cap/dipstick securely each time you check the oil Ievel,
SrAE 0W30 motor oil may be used to make starting
easier in areas where the temperature is 20 ° F or lower.
OIL RECOMMENDATION

classification SG Select the oi!'s viscosity grade accord-
ing to your expected operating temperature:
RECOMMENDED VISCOSITY GRADES
LDER_€ .{ _WARMER
5W30 SAE30
NOTE: Forextreme cold operating conditions of0 ° F and
below, use partial synthetic0W30 oil for easier starting
NOTE: Although multi-viscosity oils improve starting in
cold weather, these multi-viscosity oils will result in
increasedoilconsumptionwhen used above 32°F Check
your engine oil level more frequently to avoid possible
engine damage from running low on oil,,
Change the oil after first two hour s ofoperation and every
25 hours thereafter or at least once a year if the snow
thrower is not used for 25 hours (See Fig 20)
