maintenance operations. It is secured by a spring clip at its front end and a screw
at its rearward end. First, DISCONNECT THE ELECTRICAL POWER FOR
SAFETY. Then, remove the screw in the rear (Fig. 10 [20]), lift rear of cover,
push forward about 3 inches and lift cover off. Re-install in reverse procedure
using care to insure that the cover sits squarely and uniformly on the mixer
housing.
b. Remove rear access panel (Fig. 10 [27]) by removing eight screws and
washers (Fig. 10 [23, 24])
MECHANICS MAINTENANCE
a. Start mixer and shift speed control (Fig. 1 [9]) to the slowest speed (Low, 1).
Stop mixer.
WARNING: FOR SAFETY, DISCONNECT ELECTRICAL POWER. Place
tag or sign on electrical supply warning that MIXER IS BEING
WORKED ON; DO NOT TURN ON.
b. Remove rear access panel (Fig. 10 [22]) and top cover (Fig. 10 [17]) as
described above.
c. Inspect drive belt (Fig. 11 [2]) for proper adjustment. Outer surface of belt
should be approximately flush to 1/16" below the outer edges of the input pulley
flanges (Fig. 11 [5]) when mixer has been shut off in first speed (see Pg. 5). If
drive belt is excessively frayed or has a heavily glazed surface, replace it.
However, it is generally the best judgment to leave a drive belt in a machine if it
is performing well, even it if shows moderate wear. Inspect gripping surfaces of
drive belt for excessively glazed surfaces or contamination by grease or oil.
To replace belt, run mixer in 1st speed. Disconnect electrical supply. Shift
machine to 4th speed. Unwrap belt from top pulley. Slide belt between top
pulley nose and cam (Fig. 8 [8]). Remove belt from lower pulley.
WARNING: Lower pulley flanges are spring loaded. Keep fingers away while
removing belt.
The bowl must be lowered in order for the belt to clear the nose of the lower
pulley when removing belt. To install new belt wrap belt around lower pulley.
Pull belt into the spring loaded flanges. A pry bar will help separate the flanges.
Continue replacement in reverse order from belt removal. Adjustment of the belt
drive will most likely be required.
d. Readjustment of the drive belt, where a slight stretching or normal seating has
caused outer surface of the belt to exceed the acceptable limit of flush to 1/16"
below the input pulley flanges (see Pg. 5) is as follows:
Loosen kep nuts (Fig. 8 [12]) securing the bracket (Fig. 8 [15]) and holder(Fig. 8
[1]) to the housing. If the belt was riding outside the pulley flanges, tap the speed
control assembly lightly towards the rear of the mixer. If the belt was riding
more than 1/16" below the pulley flanges, tap the speed
Page 4
control assembly towards the front of the machine (shifting to 2nd second speed will
help).
Note: The assembly must remain perpendicular to the mixer housing walls. Failure to do
so will result in the binding of the shaft (Fig. 8 [10]) in the bearing (Fig. 8 [21]).
Retighten the kep nuts and run mixer in 1st speed and check belt position. Repeat
procedure if necessary.
e. Once the upper pulley (Fig. 11 [5]) has been adjusted, the lower pulley must be checked.
Start mixer and shift to 4th speed. Turn mixer off and check position of belt. The belt
should be flush to 1/16" below outer edges of the pulley flanges. If adjustment is needed,
loosen kep nuts (Fig. 11 [14]) and raise or lower the motor using the kep nuts on the
under side of motor. Retighten top kep nuts and run mixer in 4th speed to check new belt
position.
Note: The motor must remain level with the mixer base (Fig. 10 [1]). If not, poor shifting
and belt life will result.
WARNING: FOR SAFETY, DISCONNECT ELECTRICAL POWER.
DRIVE BELT SETUP

2. MOTOR
Check motor (Fig. 11 [16]) for overheating and excessive noise. If defective, send to a local
electrical repair shop.
3. BOWL LIFT ADJUSTMENT
WARNING: FOR SAFETY, DISCONNECT ELECTRICAL POWER.
a. Check adjustment by placing a 60 quart bowl on the lowered bowl support, and place a
60 quart batter beater on the beater shaft (Fig. 1 [1]).
b. Raise bowl support to the upper position.
c. Check clearance between bottom of the bowl and the adjacent underside of the batter beater.
Clearance should be 3/16" ± 1/16".
Page 5
d. If adjustment is required, loose jam nut (Fig. 7 [25]) and turn threaded bowl stop rod
(Fig.7 [24]) until the desired clearance is obtained, then tighten the jam nut.
4. DRIVE BELT REPLACEMENT (See CVT Belt Drive)
5. LUBRICATION
WARNING: FOR SAFETY, DISCONNECT ELECTRICAL POWER TO THE MIXER.
a. The lubrication instructions are listed in Figure 2.
b. Remove access panel (Fig. 10 [22]), top cover (Fig. 10 [17]) per page 4.
c. In order to service the gearbox, it will be necessary to further remove the gearbox cover
(Fig. 3 [2]). A thin blade putty knife will prove helpful in separating the silicone sealant
between this cover and the gearbox. Do not bend cover. Thoroughly remove all dried
sealant before applying new sealant when reinstalling the cover. Do not allow dried
sealant to enter gearbox. Silicone rubber sealant such as Dow Corning Silastic 732RTV or
Permatex Form-A-Gasket are recommended.
WARNING: NEVER WORK ON THE GEARBOX WITH THE MIXER
RUNNING.
d. Use care to avoid getting lubricant of any kind on the drive belt and pulleys as this would
seriously deteriorate the belt grip and mixer performance.
