CLEANING WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AND FOLLOW LOCKOUT / TAGOUT PROCEDURES. New mixer bowls and accessories (beaters, whips and dough arms) should be thoroughly washed with hot water and a mild soap solution, rinsed with either a mild soda or vinegar solution and thoroughly rinsed with clear water before being used. This cleaning procedure should also be followed for bowls and agitators before whipping egg whites or whole eggs. The mixer should be thoroughly cleaned daily.
MAINTENANCE WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AND FOLLOW LOCKOUT / TAGOUT PROCEDURES. LUBRICATION Fig. 11 Slideway The slideways (Fig. 11) should be lubricated approximately twice a year. To reach these areas, fully lower the bowl support and remove the apron, which is secured by thumb screws. Wipe a thin coat of Lubriplate 630AA on the bowl pad area of the bowl supports and on each slideway. Install the apron. Planetary Seal Occasionally, the planetary seal (Fig.
Transmission To check the oil level, remove the top cover, which is secured by two screws. Remove the Transmission Fill Plug (Fig. 12) and check the oil level. If the oil level is below the line on the oil dipstick, add a small amount of the recommended transmission oil until it returns to the proper level. Do not overfill the transmission, as leakage may result. Contact your local Hobart Service Office for the recommended transmission oil. Fig.
Measure Clearance Pour enough flour in the bowl to cover the bottom of the bowl where the beater travels. With the bowl fully raised (beater should not touch the bottom of the bowl), briefly run the mixer at the lowest speed. Turn off the mixer, disconnect the electrical power supply, and measure the depth of flour where the beater has traced a path. This measurement should be taken at several points around the bowl to assure accuracy.
