REMOVAL OF TOP COVER AND REAR ACCESS PANEL

The top cover (Fig. 10 [17]) must be removed in order to perform the

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 [20J),

lift rear of cover, push forward about 3 inches and lift cover off.

Reinstall in reverse procedure using care to insure that the cover sits squarely

and uniformly on the mixer housing.

Remove rear access panel (Fig. 10 [22]) by removing eight screws and

washers (Fig. 10 [23, 24}).

MECHANICS MAINTENANCE

A mechanic should perform the following inspection and maintenance as required

depending on severity of use, but at least yearly.

CVT BELT DRIVE

Start mixer and shift speed control (Fig. i

[91)

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.

Remove rear access panel (Fig. 10 [22]) and top cover (Fig. 10 [17]) as

described above.

Inspect drive belt (Fig. lI [21) for proper adjustment. Outer surface of belt

should be approximately flush to 1/16' below the outer edges ofthe input

pulley flanges (Fig. 1 1 [5]) when mixer has been shut off in first speed (see

Pg. 17).

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 ist speed. Disconnect electrical supply. Shift

machine to 4th speed. Unwrap belt from top pulley. Slide belt between top

pulley nose and cam (Fig. S [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 ofthe belt drive will most likely be required.

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

1116 below the input pulley flanges (see Pg. 17) is as follows:

Loosen Kep nuts (Fig. 8 [12]) securing the bracket (Fig. 8 [15]) and holder

(Fig. 8 [1]) to the housing. Ifthe 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
