SAVE THESE INSTRUCTIONS
GENERAL
The D300 Mixer (30 quart) features a 3/4 horsepower motor, a timer and a #12 attachment hub as
standard equipment. The standard 30 quart mixer bowl can be equipped with a variety of agitators. A
20 quart bowl, bowl adapter and agitators are available options on the D300.
Bowl Guard is standard equipment on all D300 models.
Programmable Timer Controller is optional on D300 models.
These mixers can be ordered with deluxe finish, which includes a chrome plated transmission case,

INSTALLATION
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, have the electrical service tested to assure 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.
A Deck Plate Kit is available from Hobart and 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.

Check Rotation (Three-Phase Machines Only)
Three-phase machines must be connected so the planetary rotates in the direction of the arrow on the
Drip Cup. To check rotation:
Set the gear shift lever on 1.
Apply power to the mixer, set the Electro-Mechanical Timer on HOLD or, if equipped with a
Programmable Timer Controller, set it on [ – – : – – ]. With the Bowl Support all the way up,
momentarily run the machine by pushing the START and then STOP buttons.
If rotation is incorrect, DISCONNECT ELECTRICAL POWER SUPPLY and interchange any two
of the incoming power supply leads.
