for overheating, noise and excessive end play of shaft.
qt. batter beater on
a. The top cover (Fig. 12 [16]) must be removed in order to perform the
at its rearward end. First, DISCONNECT THE ELECTRICAL POWER FOR SAFETY. Then, remove the screw in the rear (Fig. 12 [20]), forward about 3 inches and lift cover off.
b. Re-install in reverse procedure using care to insure that the cover sits squarely
and uniformly on the mixer housing.
MECHANICS MAINTENANCE
required:
1. BELTS
a. WARNING: Start mixer and adjust speed control (Fig. 1 [9]) to speed 4. Stop
mixer. FOR SAFETY, DISCONNECT POWER. b. Remove top cover (Fig. 12 [16]) and rear access panel (Fig. 12 [23]). c. Check belts (Fig. 11 [11 & 21]). If broken, glazed or worn, replace. d . Check belt (Fig. 11 [11]) for proper tension. The outer edge of the belt
should be flush with the outer diameter of the variable speed pulley (Fig. 11 [10]). If not, adjust by loosening the Jam Nut (Fig. 10 [15]) and turning the connecting rod (Fig. 10 [14]) until the outer edge of belt is flush with the outer diameter of the pulley. Retighten Jam Nut.
e. WARNING: Plug machine in, start mixer, and adjust speed control to speed 1.
Stop mixer. FOR SAFETY, DISCONNECT POWER.
f. Check belt (Fig. 11 [21]) for proper tension. The outer edge of the belt should be
flush with the outer diameter of the variable speed pulley (Fig. 11 [10]). If not, adjust by loosening nuts (Fig. 11 [13 ]), holding motor (Fig. 11 [30]), the motor until the outer edge of belt is flush with the outer diameter of pulley. Retighten Nuts.
2. MOTOR
Check motor (Fig. 11 [30])
Replace if defective.
3. BOWL LIFT ADJUSTMENT (Fig. 8 and 9)
a. Place 20 qt. mixing bowl (Fig. 1 [18]) on bowl support and 20
beater shaft (Fig. I [1]).
b. Raise bowl support to the high position.
c. Check clearance between bottom of bowl and lowest point of batter beater.
Clearance should be 3/16 inch, plus or minus 1/16 inch.
d. If adjustment is required, disconnect power, loosen lock nut (Fig. 8 [10]) and turn
linkage rod (Fig. 8 [9]) until desired clearance is obtained. Retighten lock nut.

often years. The transmission and beater head gearing are packed with Nevastane 5p7 grease. They
NEVER WORK ON THE TRANSMISSION WITH THE MIXER RUNNING. IT IS
RECOMMENDED THAT THE ELECTRICAL SERVICE BE DISCONNECTED TO PREVENT
The lubrication instructions are in Fig. 2. Motors have pre-
