MAINTENANCE

Disconnect the electrical power to the mixer and follow lockout / tagout

procedures.

Do not remove any covers or loosen any ttings while the mixer is operating.

Ensure the electrical supply has been isolated before attempting to service or move the mixer.

The electronic drive control is tted with high voltage capacitors. Isolate the

mixer from the mains and allow the capacitors to discharge for 5 minutes before removing any
covers.

Only Hobart trained service personnel or other properly trained and qualied

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

AGITATO R
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.

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.

– 20 –

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. Do not overll the
transmission, as leakage may result. Contact your local Hobart Service O󰀩ce for the recommended

transmission oil.

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, HL600C, HL800, HL800C, HL1400, HL1400C 1/8" (3 mm)

HL600, HL600C, HL800, HL800C 5/16" (8 mm)

ED Dough Arm

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.

– 21 –

Measure Clearance

Pour enough our 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), briey run the mixer at the lowest speed.

Turn o󰀨 the mixer, disconnect the electrical power supply, and measure the depth of our 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.
