Programmable Timer Controller is optional on D340 models. A variety of attachments and accessories are available for all mixers. These are described in a
separate
Use and Applications Handbook,
which is furnished with each mixer.
UNPACKING
Immediately after unpacking the mixer, check for possible shipping damage. If this machine is found to be damaged, 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 in its operating location. There should be adequate space around the mixer for the user to operate the controls and to install and remove bowls. The area above the mixer should allow the top cover to be removed for routine maintenance and servicing.
Holes are provided in the base for permanent bolting to the floor, 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.

CHANGING SPEEDS
The Gear Shift Lever is used to change speeds. Always stop the mixer before changing speeds.
1. Push the STOP button.
2. Move the Gear Shift Lever to the desired speed.
3. Push the START button to restart the mixer.
NOTE: If you do not stop the mixer to change speeds, it will automatically shut itself off and you will have to restart it after changing speeds.
Mixer Speeds
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, mashing
potatoes 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.

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.

BOWL GUARD
D340 Mixer Technical Manual Page 16 of 67
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.

ATTACHMENTS
D340 Mixer Technical Manual Page 17 of 67
To install an attachment, loosen the Attachment Hub thumb screw (Fig. 2) 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. With the Bowl Support all the way up and the Wire Cage 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.

WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AND FOLLOW
