MIXING

This section explains operation of the mixer and how to install bowls, agitators and attachments. A

separate

Use and Applications Handbook,

provided with the mixer, 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 used. 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 is installed.

To install the bowl, fully lower the Bowl Support (Fig. 2). Position the bowl so the alignment bracket on

the back of the bowl is in the bowl retainer on the Bowl Support and the alignment pins on the front of

the Bowl Support fit in the holes in the bowl. Lock the bowl in place by rotating the Bowl Clamps (Fig.

2) 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

the agitator up on the agitator shaft and turn the agitator

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):

1. Load ingredients.

2. Close the wire cage assembly.

3. Select low speed.

4. To begin mixing, press and hold the START button; then raise the bowl.

D340 Mixer Technical Manual Page 15 of 67

BOWL GUARD

The Wire Cage Assembly can be rotated out of the way to add ingredients or to access the bowl and

agitator.

Rotate the Wire Cage Assembly

Push the Latch in to release the Centering Pin from the Centering Ramp. Note how the grooves on the

nylon retainers allow the Wire Cage to ride around the circular Ridge on the Planetary Drip Cup. The

Wire Cage can rotate 360° left or right. When the Wire Cage returns to the Front-Center Position, the

Centering Pin is captured and held by the Centering Ramp, restricting rotation of the Wire Cage until

the Latch is pressed again.

The Wire Cage must be in the Front-Center Position for the mixer to operate.

Remove Wire Cage Assembly

Lower the bowl. Rotate the Wire Cage to the rear. Remove both agitator and bowl. Return the Wire Cage

to the front.

While holding the Wire Cage securely with both hands, use your thumb to push down on the Black

Release Knob. Lower and remove the Wire Cage. Wash it in a sink, 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 and dry with a clean cloth.

Reinstall Wire Cage Assembly

Hold the Wire Cage so its top ring is positioned around the Drip Cup with the grooves in both nylon Rear

Retainers straddling the Ridge on the Drip Cup. Push in the Front-Center Retainer until it stays in and

its grooves straddle the Ridge on the Drip Cup. 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 to the rear to install or remove the agitator and bowl or to add ingredients.

Return the Wire Cage to the Front-Center Position to operate the mixer.

in the Front-Center Position (Fig. 5), 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, push the STOP button at once. Do not attempt to restart the mixer in a lower

speed; remove the adjusting ring, knife, plate and worm and clear any obstruction.

Note: This attachment must not be used to chop bread crumbs.

Bowl Scraper Attachment

The Mixer bowl scraper attachment (when ordered) is provided with a separate instruction manual

covering its installation, operation, use and care.

CLEANING

WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AND FOLLOW

LOCKOUT / TAGOUT PROCEDURES.

A flat scraper and a brush are furnished to aid in cleaning bowls and agitators.

The mixer should be thoroughly cleaned daily. Do not use a hose to clean the mixer; wash with a clean,

damp cloth. The base allows ample room for cleaning under the mixer. The apron may be removed by

loosening the thumb screws. Behind this apron is an access cover which may be removed for cleaning.

The Drip Cup-Splash Guard Assembly (Fig. 5) should be removed periodically and wiped clean.

MAINTENANCE

WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AND FOLLOW

LOCKOUT / TAGOUT PROCEDURES.

LUBRICATION
