3. TRANSMISSIONS: This machine is equipped with two Euclid gear reducer transmissions- one for the
mixer drive (No. 300V) and one for the auger drive (No. CH300V). The mixer drive (300V) and the
auger drive (CH300V) hold 1¼ pints of oil each. This amount brings the lubricant level up to the side
“ll level” hole. Oil should be changed after six (6) weeks of operation initially and subsequently every
six (6) months thereafter using Mobilgear 630 oil or equivalent.
