ADJUSTMENTS
Agitator Clearance
The agitator clearance should be checked with each bowl change. The agitator must not touch the bowl
and the maximum clearance between the bottom of the bowl and the B Flat Beater is
1
⁄8"; the maximum
clearance between the bottom of the bowl and the E or ED Dough Arm is
5
⁄16".
Install a Bowl and Agitator. If the Bowl and Beater come into contact before the Bowl Support reaches
its stop, adjust the Stop Screw upwards following the procedure below.
To Measure the Clearance . . .
Pour enough flour in the bowl to cover the bottom of the bowl where the beater travels. With the bowl
fully raised, briefly run the mixer in speed 1.
Turn off the mixer, DISCONNECT ELECTRICAL POWER SUPPLY, and measure the depth of flour
where the beater has traced a path. This measurement should be taken at several points around the
bowl to assure accuracy.
To Adjust the Bowl / Agitator Clearance . . .
• Remove the Apron (which is secured by 4 thumbscrews).
• Loosen the bottom Locking Nut (Fig. 8), and turn the Stop Screw counterclockwise to increase
the clearance or clockwise to decrease the clearance.
• Tighten the Locking Nut while holding the Stop Screw.
Caution: Make sure the switch button on the bowl height sensing switch is never below the bottom
of the nylon actuator.
• When the Bowl Support is fully raised, the Switch Button on the Bowl Height Sensing Switch
should be
1
⁄8" above the bottom of the Nylon Actuator. If necessary, adjust the Locking Nuts
above and below the Nylon Actuator to move it up or down.
• After the adjustments are made, replace the Apron.
• Reconnect the electrical power supply.
• Carefully operate the bowl lift several times to check the adjustment.

Bowl Clamps
The height of the bowl clamp is controlled by a spring washer and lock nut, which are located on the
bottom of the bowl support. Turning the lock nut clockwise will loosen the clamp, counterclockwise will
tighten it. If repeated adjustments are necessary, additional service is indicated. Contact your local
Hobart Service Office.
