Gear Case
• The gear case is lubricated with grease at the
factory and does not require checking. If
disassembled for any reason, lubricate with two
ounces of Shell Alvania grease.
Wheel Chain Case
• The wheel chain case is equipped with a grease
fitting. A cold weather multi-purpose grease
should be pumped (only two times) into chain
case every 25 hours of operation. Exceeding
this may cause grease to leak out of the chain
case when warm.

to support bracket for reassembly.
Bearings
• Once a season lubricate auger bearings and the
bearings on the side of the frame with light oil.
