Checking the Auger Gearbox
Grease
Service Interval: Yearly
The auger gearbox is packed with 5 oz. (140 g) of
Lubriplate MAG-1 (a low-temperature, high-pressure
grease) and is sealed at the factory. The pipe plug
(Figure 25) is for factory use only; you do not need to
check or add grease. If the gearbox is leaking grease,
contact an Authorized Service Dealer.

Changing the Engine Oil

Service Interval: After the first 2 hours
Yearly
Every 25 hours
Change the engine oil after the first 2 operating hours,
then yearly thereafter. If possible, run the engine just
before changing the oil because warm oil flows better
and carries more contaminants.
