This cleaning procedure should also be followed for bowls and agitators before whipping egg whites or whole eggs.

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 (Fig. 3, Fig. 4, and Fig. 5) may be removed for cleaning by loosening the thumb screws. DO NOT wipe down slideways (Fig. 15) when cleaning.

The drip cup-splash guard assembly (Fig. 3, Fig. 4, and Fig. 5) should be removed periodically and wiped clean.

For cleaning the wire cage refer to the Wire Cage section.

MAINTENANCE

⚠ WARNING Disconnect the electrical power to the mixer and follow lockout / tagout procedures.
⚠ WARNING Do not remove any covers or loosen any fittings while the mixer is operating. Ensure the electrical supply has been isolated before attempting to service or move the mixer.
WARNING The electronic drive control is fitted with high voltage capacitors. Isolate the mixer from the mains and allow the capacitors to discharge for 5 minutes before removing any covers.
⚠ WARNING Only Hobart trained service personnel or other properly trained and qualified personnel should carry out service.

INTERLOCK SAFETY SYSTEM

Regular inspection of the mixer's safety system is necessary to check the operation of the wire cage and bowl support interlock switches. Inspections must be performed no less than once a year.

A spare parts manual is available from Hobart Resource Center. For continued safe and reliable operation of this mixer, it is recommended that servicing is only carried out by Hobart trained service personnel.

LUBRICATION

PLANETARY SEAL SLIDEWAYS AGITATOR SHAFT

Fig. 15

Slideways

The slideways (Fig. 15) should be lubricated approximately twice a year. To reach these areas, fully lower the bowl support and remove the apron (Fig. 3, Fig. 4, and Fig. 5), which is secured by thumb screws. Wipe a thin coat of Lubriplate 630AA on the bowl pad area of the bowl supports and on each slideway. Install the apron.

Planetary Seal

Occasionally, the planetary seal (Fig. 15) may become dry and begin to squeak. To correct this, work a little lubrication (mineral oil) under the lip of the seal.

Agitator Shaft

The agitator shaft (Fig. 15) should be lubricated twice a year with a thin coat of mineral oil.

Transmission

To check the oil level, remove the top cover, which is secured by two screws. Remove the Transmission Fill Plug (Fig. 16) and check the oil level. If the oil level is below the line on the oil dipstick, add a small amount of the recommended transmission oil until it returns to the proper level.

Fig. 16

TRANSMISSION BELT

The transmission belt should be inspected yearly for wear and replace by a Hobart Service Technician if worn.

ADJUSTMENTS

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 an agitator is:

Agitator Models Max Clearance
B Flat Beater HL600	0, HL600C, HL800, HL800C, HL1400, HL1400C 1/8" (3 mm)
ED Dough Arm	HL600, HL600C, HL800, HL800C 5/16" (8 mm)
	HL1400, HL1400C 11/16" (17 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 the Adjust the Bowl/Agitator Clearance section.

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.

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 (Fig. 3, Fig. 4, and Fig. 5) (which is secured by thumbscrews).
• Adjust the stop screw on the left side (80-Qt and 140-Qt) and the right side (60-Qt).

- Loosen the bottom locking nut, (Fig. 17) 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.

• After the adjustments are made, replace the apron and secure it with the thumbscrews.
• Reconnect the electrical power supply.
- Carefully operate the bowl lift several times to check the adjustment.

Bowl Lock Lever (Fig. 18)

• Occasionally debris may collect and cause the lever to move slowly.
- Pour very warm water around lock pin to flush out food particles that may have collected there. The water should flow through, around the pin. Be sure to have a cloth or dish under to bowl support to catch the water and food particles.
- Lubricate the pin with a thin coat of Lubriplate 630AA.
