Wire Cage Cleaning
- Remove and clean wire cage:
1. Lower the bowl. Remove the agitator and bowl
2. While holding the wire cage securely with both hands, rotate it to your left until the front-center retainer shoe reaches the gap in the circular ridge of the planetary drip cup
3. Lower the front of the wire cage and move the wire cage slightly to the rear so the rear retainer shoes clear the ridge of the drip cup. The wire cage can now be removed
4. Wash the wire cage in a sink, rinse with clear water, and dry with a clean cloth
5. The stainless steel splash guard can be wiped off and/or washed with a cloth or sponge using warm, soapy water. Rinse with clear water and dry with a clean cloth
Reinstall Wire Cage:
1. Position the ring of the wire cage so the front-center retainer shoe is positioned below the gap in the circular ridge of the planetary drip cup
2. Position the grooves so the rear retainer shoes straddle the circular ridge on the planetary drip cup
Initial Mixer Check
- Perform checks before use
WARNING! To avoid risk of serious injury, keep hands, feet, clothing, and utensils away from the bowl, bowl support, slideways, and agitator when the mixer is in operation or when any of the components are moving
WARNING! This food mixer is only for professional use by properly trained persons
WARNING! Ensure operators have read and understood this manual and have received proper training
WARNING! Do not use the mixer without the interlocked wire cage in place
The Legacy+® mixer is equipped with SmartTimer™ controls and a power bowl lift. Other operating parts and their functions are described throughout the Operation section
- The wire cage must be in position or the mixer will not operate
- The bowl must stay in the locked position on the bowl support or the mixer will not operate
- If the bowl support is not all the way up (mix position), the mixer will not operate unless the START button is pressed and held
1 Daily Mixer Cleaning
WARNING! Disconnect the electrical power to the mixer and follow lockout / tagout procedures
Clean the mixer
New mixer bowls and accessories (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
The mixer should be thoroughly cleaned daily. DO NOT use a hose to clean the mixer; it should be washed with a clean, damp cloth. The base allows ample room for cleaning under the mixer. The apron may be removed for cleaning by loosening the thumb screws. DO NOT wipe down slideways when cleaning
The drip cup-splash guard assembly should be removed periodically and wiped clean
For cleaning the wire cage refer to the Wire Cage section

Agitator Maintenance
- Check agitator clearance periodically
1. The agitator must not touch the bowl, and the maximum clearance between the bottom of the bowl and an agitator is:
Agitator | Models | Max Clearance:
B Flat Beater | HL600, HL600C, HL800, HL800C, HL1400, HL1400C | 1/8" (3 mm)
ED Dough Arm | HL600, HL600C, HL800, HL800C | 5/16" (8 mm)
ED Dough Arm | HL1400, HL1400C | 11/16" (17 mm)
2. 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 the Adjust the Bowl/Agitator Clearance section
3. Measure 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
