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.
