MECHANICS MAINTENANCE

a. WARNING: Start mixer and adjust speed control (Fig. 1 [8]) to speed 4. Stop

mixer. FOR SAFETY, DISCONNECT POWER.

Remove top cover (Fig. 12 [12]) and rear access panel (Fig. 12 [23]).

c. Check belt (Fig. 11 [2]). If broken, glazed or worn, replace.

d. Check belt (Fig. 11 [2]) for proper tension. The outer edge of the belt should be

flush with the outer diameter of the variable speed pulley (Fig. 11 [1]). If not,
adjust by loosening the jam nut (Fig. 11 [11]) 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.

Check motor (Fig. 11 [19])

3 BOWL LIFT - ADJUSTMENT: (Fig. 8 and 9)

a. Place 12 qt. mixing bowl (Fig. 1 [18]) on bowl support and 12

beater shaft (Fig. 1 [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 bolts (Fig. 9 [10]) and raise

lower bowl until desired clearance is obtained. Retighten bolts.

4 LUBRICATION

The lubrication instructions are in Fig. 2. The transmission and beater head gearing are
packed with Nevastane 5P7 grease. They must be re-packed every 500 hours of operation.

WARNING: NEVER WORK ON THE TRANSMISSION WITH THE MIXER RUNNING. IT IS
RECOMMENDED THAT THE ELECTRICAL SERVICE BE DISCONNECTED TO
PREVENT ACCIDENTAL START UP.

c. Reassembly should be carried out in the reverse of the disassembly

procedures stated above. Successful reassembly is very dependent on th
cleanliness of all surfaces particularly the bores of housings, gears and
bearings as well as the outer surface of shafts. It is well to recheck each
component for cleanliness as it is picked up for reassembly. New keys and
roll pins should be used on reassembly.
