Electrical Connections 
CAUTION: 

Before making electrical connections be sure that current and voltage of the 

mixer are identical to those of electrical inlet lines. 
20 quart, 110 volt mixers are furnished with a six (6) foot flexible power cord.   
On 30 quart mixers the line cord is to be supplied by the customer.  Connections are made 
inside the mixer column through the cover plate located on the back side of the column 
near the bottom.  NOTE: A six (6) foot flexible three (3) prong cord is available as an extra 
cost option. 
IMPORTANT: On 3 phase mixers, after electrical connection has been made, be sure the 
mixer operates in a counter-clockwise direction as indicated by the arrow located above 
the attachment.  If electrical connection is reversed the transmission will not shift, nor will 
the planetary action function. 

 

Transmission Oil 

After the first 200 hours of operation and every 6 months thereafter the transmission oil 
must be changed. 
When adding or changing transmission oil use 50 S.A.E. heavy duty oil.  3 pints required.
