OPERATION
WARNING: MOVING BEATER IN BOWL. KEEP HANDS, CLOTHING, AND UTENSILS OUT WHILE
IN OPERATION.
CONTROLS
The ON-OFF SWITCH is used to start and stop the mixer. 
The GEAR SHIFT LEVER (Fig. 1) is used to change speeds. Always stop the mixer before changing
speeds. To change speeds, turn the switch Off, move the gear shift lever to the desired speed, and 
turn the switch back On. NOTE: There is a mechanism which prevents the gear shift lever from 
being moved with the switch in the ON position, and also prevents the switch from being turned ON if 
the gear shift lever is between gears.
Speed 1 (Low) — This speed is for 
heavy mixtures such as bread dough, 
heavy batters, and potatoes.
Speed 2 (Medium) —This speed is 
for light dough which must rise 
quickly, cake batters, and some 
whipping operations.
Bowl Clamp
Speed 3 (High) — This is a fast 
speed for light work such as whipping 
cream, beating eggs, and mixing thin 
batters.
The BOWL LIFT HANDLE is used to 
raise and lower the bowl. To raise 
the bowl, rotate the handle upward; 
rotating the handle downward lowers

the bowl.

MIXING
This section explains operation of the mixer and how to install bowls, agitators, and attachments. A 
separate 
Use and Applications Handbook
 is provided with the mixer which contains information on
mixing procedures and outlines specific uses for agitators, attachments, and accessories.
Bowl
New mixer bowls and agitators (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 put into service. This cleaning procedure should also be 
followed for bowls and agitators before whipping egg whites or whole eggs.
The bowl must be installed before the agitator. To install the bowl, fully lower the bowl support (Fig. 1). 
Position the bowl so the alignment bracket on the back of the bowl is in the bowl retainer and the 
alignment pins (Fig. 1) on the front of the bowl support fit in the holes on the sides of the bowl. Lock 
the bowl in place by rotating the bowl clamps (Fig. 1) over the ears of the bowl.
Agitator
To install an agitator, the bowl must be installed and fully lowered. Place the agitator in the bowl, push 
it up on the agitator shaft (Fig. 1), and turn it clockwise to seat the shaft pin in the slot of the agitator 
shank.

Attachments
To install an attachment, loosen the thumb screw on the attachment hub (Fig. 1) and remove the plug. 
Insert the attachment into the attachment hub making certain that the square shank of the attachment 
is in the square driver of the mixer. Secure the attachment by tightening the thumb screw.
Move the gear shift lever to the desired speed and start the mixer to operate the attachment. 
The meat and food chopper attachment should be operated in second or third speed. If material in the
cylinder stalls the mixer, stop the mixer at once. DO NOT attempt to restart the mixer in a lower speed 
— remove the adjusting ring, knife, plate, and worm and clear the obstruction. THIS ATTACHMENT 
MUST NOT BE USED TO CHOP BREAD CRUMBS.
NOTE: Attachment hub should not be used while mixing.
CLEANING
WARNING: UNPLUG MACHINE POWER CORD BEFORE BEGINNING ANY CLEANING PROCEDURE.
The mixer should be thoroughly cleaned daily. 
Bowls and agitators should be removed from the mixer and cleaned in
a sink. 
DO NOT use a hose to clean the mixer — it should be washed with a
clean damp cloth. 
Remove the agitator spring for cleaning. Slip the lower end of the spring
underneath the agitator pin and screw in a counterclockwise motion until 
the spring comes off (Fig. 2). After cleaning, reinstall the agitator spring 
by reversing this procedure. All coils of the spring should be above the 
agitator pin.  DO NOT OPERATE AGITATORS WITHOUT THE
AGITATOR SPRING IN PLACE.
The drip cup (Fig. 1) should be removed periodically and wiped clean.

three surfaces of both slideways.
