Installation, Operation, and Care of

A200 MIXER

SAVE THESE INSTRUCTIONS

GENERAL

The model A200 mixer is a 20 quart, bench-type mixer with a 1/2 H.P. motor, and a #12 attachment hub. With the use of special agitators, a 12 quart bowl may be used on the A200 mixers.

The floor model and the deluxe finish model are equipped with a timer.

Most A200 mixers are equipped with a 0 - 15 minute timer.

There are a variety of attachments and accessories available for all models, and these are explained in a separate Use and Applications Handbook which is supplied with each mixer.

INSTALLATION

UNPACKING

Immediately after unpacking the mixer, check for possible shipping damage. If this machine is found to be damaged after unpacking, save the packaging material and contact the carrier within 15 days of delivery.

Prior to installation, test the electrical service to assure that it agrees with the specifications on the machine data plate.

LOCATION

Place the mixer on a suitable sturdy level surface. There should be adequate space around the mixer for the user to operate the controls and install and remove bowls.

Holes are provided in the base to permanently secure the mixer, although this is not necessary in normal installations. Four plastic plugs are supplied with the mixer to plug these holes if they are not used.

ELECTRICAL CONNECTIONS (Cord Connected Mixers)

WARNING: THE ELECTRICAL CORD ON THIS MACHINE IS EQUIPPED WITH A THREE-PRONGED GROUNDING PLUG WHICH MUST BE CONNECTED TO A PROPERLY GROUNDED RECEPTACLE. IF THE RECEPTACLE IS NOT THE PROPER GROUNDING TYPE, CONTACT AN ELECTRICIAN. DO NOT REMOVE THE GROUNDING PRONG FROM THE PLUG.

OPERATION

WARNING: MOVING BEATER IN BOWL. KEEP HANDS, CLOTHING, AND UTENSILS OUT WHILE IN OPERATION, DO NOT USE WITHOUT INTERLOCKED GUARD.

CONTROLS

All models are furnished with an On-Off toggle switch which controls power to the mixer.

The Bowl Guard must be in position or the mixer will not operate. Refer to page 6.

If the Bowl Support is not all the way up, the mixer will not operate unless the On-Off switch is held in the up position.

The TIMER (if equipped) is used in conjunction with the On-Off switch for timed mixing operations and will stop the mixer when the desired time has elapsed.

With the timer set on HOLD, the mixer will run until the On-Off switch is turned to Off.

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.

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.

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 (Fig. 1) 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 (Fig. 1), the bowl must be installed and fully lowered. Place the agitator in the bowl, push it up on the agitator shaft, and turn it clockwise to seat the shaft pin in the slot of the agitator shank.

To Raise the Bowl While Mixing

To raise the bowl while the agitator is mixing the product (when required by recipe or when using the Bowl Scraper Attachment): Load ingredients. Close Wire Cage Assembly. Select Low speed. To begin mixing, hold the On-Off switch in the up position; then raise the bowl.

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.

Bowl Scraper Attachment

The Mixer Bowl Scraper Attachment (when ordered) is provided with a separate instruction manual covering its installation, operation, use and care.

Bowl Guard (Fig. 2)

The Wire Cage Assembly on the Bowl Guard can be rotated out-of-the-way to add ingredients or access the bowl and agitator.

To rotate the Wire Cage Assembly to the rear . . .

Rotate the Wire Cage Assembly to the left until it is positioned underneath the Splash Guard. Note how the grooves on the nylon Retainers allow the Wire Cage to ride around the circular Ridge of the planetary Drip Cup.

The Wire Cage must be returned to the front and center position for the mixer to operate.

To remove the Wire Cage Assembly for cleaning . . .

Lower the Bowl. Rotate the Wire Cage Assembly to the left until it is positioned underneath the Splash Guard. Remove both Agitator and Bowl.

While holding the Wire Cage Assembly with both hands, rotate it completely to the left. When the frontcenter Retainer reaches the end of its travel, it can be lowered through the flat on the Ridge of the Drip Cup. After lowering the front-center Retainer, move the Wire Cage Assembly slightly to the rear so the Rear Retainers clear the Ridge on the Drip Cup. The Wire Cage Assembly can now be lowered and removed.

Wash the Wire Cage in a sink or dishwasher; rinse with clear water; and dry with a clean cloth.

The stainless steel Splash Guard can be wiped off or washed easily with a cloth or sponge and warm soapy water. Rinse with clear water. Dry with a clean cloth.

To reinstall the Wire Cage Assembly . . .

Hold the Wire Cage so its top ring is positioned around the planetary Drip Cup with the grooves in both nylon Rear Retainers straddling the Ridge on the Drip Cup at the rear. Lift the Wire Cage Assembly so the front-center Retainer passes up through the flat on the Ridge of the Drip Cup and rotate the Wire Cage Assembly to the right. The Wire Cage is properly assembled when all three Retainers straddle the Ridge on the Drip Cup in the three opposed locations. Rotate the Wire Cage Assembly to the right until it stops at the front-center position.

Rotate the Wire Cage out-of-the-way to install or remove the Agitator and Bowl or to add ingredients.

Return the Wire Cage to its front-center position to operate the mixer.

LUBRICATION

Bowl Clamps (Fig. 1) should be lubricated twice a year.

Motor
