11.2 ADJUSTMENTS
11.2.1 AGITATOR CLEARANCE.
The agitator clearance should be checked
periodically. 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” (3 mm); the maximum clearance
between the bottom of the bowl and the ED dough is 5/16" (8 mm). Install a bowl and
agitator (e.g., beater) If the bowl and beater come into contact before the bowl support
reaches its stop, adjust the stop screw. Refer to Adjust the Bowl/Agitator Clearance,
Section 11.2.2.
11.2.2 TO MEASURE THE AGITATOR CLEARANCE.
Pour enough flour in the bowl to cover the bottom of the bowl where the beater
travels. With the bowl fully raised (beater should not touch the bottom of the
bowl), briefly run the mixer at the lowest speed.
Turn off the mixer, disconnect the 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.
Adjust the Bowl/Agitator Clearance
• Remove the apron (which is secured by
slotted screws).
• Adjust the stop screw on right side.
• Loosen the bottom locking nut, (Fig. 12)
and turn the stop screw anti-clockwise to
increase the clearance or clockwise to
decrease the clearance. Tighten the
locking nut while holding the stop screw.
• After the adjustments are made, replace the
apron and secure it with the slotted screws.
• Reconnect the electrical power supply.
• Carefully operate the bowl lift several times to check the adjustments.
11.3 INTERLOCK SAFETY SYSTEM.
Figure 12.
Regular inspection of the mixer safety system is necessary to check the operation of the
bowl, guard and bowl support interlock switches. This must be performed no less than
once a year.
A spare parts manual is available on request from Hobart Spare Parts Distribution
Centre. For continued safe and reliable operation of this mixer, it is recommended that
servicing is only carried out by Hobart trained service personnel.
