Frequently Asked Questions - HL400 Hobart

What is the maximum bowl capacity for the Hobart HL400?

The Hobart HL400 is available with bowls from 60 to 140 quarts (approximately 57 to 133 liters). Check the nameplate for the exact capacity of your model.

How do I properly install the bowl on the mixer?

Lower the bowl carriage using the motorized control, position the bowl so that the alignment pins fit into the holes, then rotate it into the locked position. Make sure the locking lever is engaged.

Which agitators are compatible with the Hobart HL400?

Available agitators include the flat beater (B), wing beater (C), standard whip (D), dough hook (ED), heavy-duty whip (I), and pastry knife (P). Use only agitators suitable for your bowl size.

How do I use the SmartTimer™?

You can use count-up mode (continuous mixing) by turning the TIME selector to HOLD, then pressing START. For countdown, turn the TIME selector to set the desired time, then press START. The timer stops automatically at zero.

What should I do if the agitator hits the bowl during operation?

First check that the bowl is properly locked. If the problem persists, adjust the agitator clearance by adjusting the stop screw on the side of the bowl carriage (see Maintenance section of the manual). The recommended maximum clearance is 1/8 inch (3 mm) for the flat beater.

How do I clean the Hobart HL400 mixer?

Turn off the power and lock the machine. Wash the bowls and agitators with hot soapy water, rinse, and dry. The guard can be removed and hand washed. Never use a hose or pressure washer. Wipe the exterior with a damp cloth.

How often should the slides be lubricated?

The slides should be lubricated about twice a year with Lubriplate 630AA grease. Lower the bowl carriage, remove the apron, apply a thin layer to the supports and slides, then reinstall the apron.

What should I do if the mixer doesn't start?

Check that the guard is fully closed in the front center position, the bowl is locked, and the bowl carriage is fully raised. Also check the fuse or circuit breaker. If the problem persists, contact Hobart technical service.

Can I use a bowl smaller than the standard size?

Yes, smaller size bowls are available (for example, a 40-quart bowl for a 60-quart model). You must use the agitator suited to the reduced bowl size. Check the Hobart website for references.

How do I maintain the transmission of the Hobart HL400?

Check the transmission oil level monthly via the dipstick under the top cover. Add recommended Hobart transmission oil if low. A complete oil change must be performed by an authorized technician. The transmission belt should be inspected annually.

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.

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, 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.
