7.0 MIXING CAPACITY.
MIXER CAPACITY
The Mixer Capacity Chart is a guide for controlling the batch sizes in your formulations. The capacities
listed take into account the amount of product, which can be contained in the various sized bowls. The
listed capacities are the maximum recommended batch sizes. If the combined weight of the bowl and
ingredients is greater than 25kg a bowl truck must be used. Recipes for dough used to establish the
batch sizes in the Mixer Capacity Chart are listed below:
Do not exceed the specifi ed mix quantity.
The maximum capacity of the mixer bowls are:
HL800 (full size): 75.7 liters
HL1400/HL1400N (full size): 132.5 liters
INGREDIENT
Flour 100.0% 100.0% 100.0%
Water 55.0 50.0 65.0
Yeast 2.0 1.0 5.0
Salt 2.5 1.5 2.5
Sugar 5.0 - 0 - 15.0
Shortening 5.0 - 0 - 15.0
Oil -0- 2.0 -0Non-Fat Dry Milk 6.0 - 0 - 8.0
Total 175.5% 154.5% 210.5%
The ingredient percentages are based on a fl our content of 100 percent to simplify using the recipes to
make various sized batches and compute the moisture absorption ratio.
The fl our used in the recipes is hard wheat fl our, enriched and bleached. It contains 11 to 12 percent
protein content and 12 percent moisture content.
Flour, which has lower moisture content, will decrease the moisture absorption, cause diffi culty in proper
gluten hydration, and make a heavier load on your mixer. Flours containing high quality protein, such as
high gluten fl our, result in dough, which can be very diffi cult to mix. If high gluten fl our is used, reduce
the batch quantity noted on the Mixer Capacity Chart by 10 percent to prevent overloading of the mixer.
HEAVY BREAD
DOUGH
MEDIUM PIZZA

RAISED DONUT
DOUGH
The temperature of the water used in the recipes is 18°C to 23.0°C. Cooler water temperatures will
cause the dough to be harder to mix. If you plan to mix doughs using cold water, the batch size may
need to be reduced by 15 to 20%.
Also considered and noted on the Mixer Capacity Chart is the moisture absorption ratio (AR). This is
the ratio of the weight of water to the weight of fl our expressed as a percentage.
AR = weight of water ÷ weight of fl our * 100%
The absorption ratio gives an indication of the relative “heaviness” or “wetness” of a batch. In fact, the
capacities listed on the Mixer Capacity Chart for the products listed below are based on the following
absorption ratios:
14
PRODUCT ABSORPTION RATIO
Heavy Bread Dough 55%
Medium Bread
Dough
Light Bread Dough 65%
Thin Pizza Dough 40%
Medium Pizza Dough 50%
Thick Pizza Dough 60%
Raised Donut Dough 65%
Whole Wheat Dough 70%
When mixing any of the above products with an absorption ratio lower than listed, decrease the batch
size proportionately to assure effi cient mixing of the product and thus eliminate the possibility of
overloading your mixer. For example: An HL800 mixer has a thin pizza dough capacity of 38.6 kg at fi rst
speed based on an AR of 40% according to the Mixer Capacity Chart. If the batch has an AR of 30%,
reduce the batch size to compensate for the difference. Compute the size of the reduction as follows:
60%
1. Divide the AR of the batch to be
mixed by the AR listed on the Mixer
Capacity Chart.
2. Multiply the rated batch size by the
percentage obtained in step 1. The
result is the maximum batch size
of the HL800 mixer for pizza dough
with 30% AR.
Another factor often overlooked is the ability of your mixer to operate at a different speed. To prevent
overloading, use the recommended mix speed from the Mixer Capacity Chart. Because of the toughness
of a 40% AR thin pizza dough, a maximum mix time of 5 minutes on fi rst speed is recommended. To
mix 50% AR or lower doughs on second speed on model HL800 and HL1400, reduce the batch size
by 50%.
The speed of the mixer, length of mix time, room temperature and ingredient temperatures all affect
dough temperature. To achieve the desired fi nal dough temperature, you may need to adjust the water
temperature.

8.0 MIXER AGITATORS.
AGITATORS AND THEIR USES
Hobart Quick Release ™ agitators are available for the Legacy mixers and for the type of product that
is being mixed.
The B Flat Beater is a multi-purpose agitator used for mashing potatoes or other vegetables, and mixing cakes, batters
or icings. It is also used in industrial applications for any
product requiring a creaming or rubbing action and uniform
dispersion of ingredients. Use fi rst speed for starting most
operations; medium speed for fi nishing.
The D Wire Whip is designed for maximum blending of air
into light products. Uses include: whipping cream, beating
egg whites, mixing very light icings, meringues and all similar
applications. The D Wire Whip is most commonly used in
third and fourth speed.
The ED Dough Hook is used for mixing most bread, roll and
pizza dough, which require folding, and stretching action for
best development. These agitators are suitable for use on all
yeast raised doughs and should be operated in fi rst, second
or third speed.
The C Wing Whip is used for whipping material that is too
heavy for the D Wire Whip. The heavy frame permits its use
for light creaming and beating. It is often used for whipping
or blending potatoes, butter, and mayonnaise or light icings.
It is generally used in fi rst and second speed for whipping
heavy products like potatoes or in third or fourth speed for
light products such as mayonnaise or icings.
The P Pastry Knife combines shortening with fl our, and is
ideal for light pastry shells (patty shells), fl aky pie dough
and similar mixes. The cutting action of the knife practically
eliminates rubbing and allows delicate ingredients to be combined without over development. The P Pastry Knife is suitable for stirring operations in low speeds and for fast cutting
operations in medium speeds. You should not use the
P Pastry Knife at high speed if you want the pastry to have a
fl aky texture.
The I Wire Whip makes sponge cakes and mixes marshmallow and icing for heavy whipping.
20
8.2 SPLASH COVER AND BOWL EXTENSION RING
Splash Covers and Bowl Extension Rings provide a means for minimizing dust emissions and reducing
splashing for certain mixes at higher speeds. Splash covers fi t under the Bowl Guard. The stainless
steel Bowl Extension Ring is also available. Splash Covers and Bowl Extensions, while convenient
accessories, should not be used to increase the mixing capacity beyond the recommended maximum.
The best functioning of Hobart mixers requires room at the top of the bowl for aeration and manipulation.
Follow the Hobart Mixer Capacity Chart of the best quality of mix. Splash Covers on larger mixers have
a smaller diameter opening at the top due to their inverted cone shape. Overloading the mixer while a
splash cover is in use reduces aeration because of restriction in the area where air enters the batch.
8.3 BOWL SCRAPER ATTACHMENT.
The mixer Bowl Scraper Attachment is available for the HL800/HL1400/HL1400N Mixer full and half
size bowls. This attachment scrapes the sides of the bowl as the agitator rotates to re-introduce material
into the mixture. The scraper must only be used with the whip or fl at beater agitators.
8.4 BOWL TRUCK.
When maneuvering or lifting a bowl and contents with a total weight in excess of 25 kg a bowl truck
must be used.
Bowl Trucks or dollies provide convenience, save time, and reduce effort in handling large batches.
Remove heavy batches of dough or batter from the mixer by unlocking the bowl and lowering on to the
Bowl Truck. Carefully roll the truck away to make room for the next batch. Move the material to another
location where it is to be used, or refrigerate between mixing and further processing. Bowl Trucks save
time, reduce handling, and improve workfl ow. These are all valuable tools in a work place.
9.0 CLEANING.
Cleaning new mixer bowls and accessories. Before using the fi rst time, thoroughly
wash new mixer bowls and agitators (beaters, whips, dough hooks and pastry knives). Wash in
hot water and a mild detergent solution, rinsing with either a mild soda or vinegar solution, and
thoroughly rinse with clear water. Also follow this cleaning procedure for bowls and agitators
before whipping egg whites or whole eggs.
9.1 CLEANING AFTER USE.
After use, clean the mixing bowl, agitators and attachment with hot water, using a suitable non-abrasive
detergent and soft bristle brush. (Flushing the bowl with hot water immediately after use will ease the
cleaning).
NOTE: Do not clean the aluminium agitators in a dishwasher.
Clean the mixer with a hot damp cloth; thoroughly wipe the bowl support arms and all exterior surfaces.
The guard should be cleaned as follows.
CLEANING THE GUARD
The guard should be cleaned at the end of each day. Once the guard is removed (see Section 6.11
page 13) it can be cleaned with hot water, using a suitable non-abrasive detergent and soft bristle
brush. The stainless steel splashguard can be wiped off and/or washed with a cloth or sponge them
using warm soapy water. Rinse with clean water and dry with a clean cloth.

10.1 UNPACKING AND HANDLING.
Wherever possible the food mixer should be transported to the installation position in
the packaging provided to avoid damage. Do not use a sharp knife to cut into the box
as damage to the machine may occur. Check for possible shipping damage. If the
unit is found to be damaged, save the packaging material and contact your nearest
Hobart sales offi ce.
The HL800/HL1400/HL1400N mixer is a heavy object and must be correctly handled
and lifted to avoid personal injury. Refer to Table 1, page 24 for weights and dimensions. For
UK installations refer to the ‘Manual Handling Operations Regulations 1992 and HSE guidance
notes for manual handling.
With the machine in the vicinity of its fi nal position, remove from outer carton. Remove mounting bolts
under skid attached to mixer base. Remove mixer from skid forking from the side of unit. When moving
unit, always fork from side of unit.
24
Care must be taken during this operation to ensure:
a) All required safety measures are taken to ensure correct lifting and handling to avoid risk of
injury through dropping, falling and tilting.
b) No damage occurs to the machine, which could impair the normal operation.
10.2 LOCATION.
The mixer is not suitable for outdoor installation and must not be installed where a
water jet could be used for cleaning. The mixer must only be operated by trained staff and must
be installed in an area where the use and maintenance is restricted to trained personnel.
The mixer must be installed on a horizontal fl at surface level to a minimum of 1mm in 1 metre side to
side and front to back. Select a suitable fl at level surface that can support the weight of the mixer and
bowl contents when full (refer to Table 1 for weights and dimensions). In areas where stability may be
an issue, the machine should be secured in position.
Once in position, the mixer must be levelled:
• Remove the two top cover screws and the top cover.
• Place a level on the top rim of the large pulley (Fig. 9). Slide shims under the base contact surface
of the mixer as required levelling it front-to-back and side-to-side.
• Do not replace the top cover until installation is completed.
Fig. 9
Ensure there is suffi cient space around the mixer for the user to operate the controls and to install and
remove bowls. The area above and to the rear side of the mixer should allow the top and rear covers to
be removed for routine maintenance and servicing. Servicing may be more diffi cult because of reduced
clearances and you should always check that equipment specifi cations permit the close proximity of
other equipment. Refer to Fig. 7, page 22 (HL800) and Fig. 8, page 23 (HL1400/HL1400N) for the
overall dimensions of the mixer and the clearance required to accommodate the hinged bowl.
25
10.3 ELECTRICAL INSTALLATION.
The electrical installation of the mixer must conform to the local electricity board regulations. When
installed in the United Kingdom the installation must be in accordance with the current edition of the IEE
Regulations for electrical equipment in buildings and must conform to the requirements of the Electricity
at work act.
A competent person must carry out the electrical installation.
The technical data shown in Table 1, page 24 details the electrical requirements for various mixer
options.
The HL800/HL1400/HL1400N mixers are “class I” appliances where the protection against electric
shock does not rely solely on basic insulation. An external electrical isolator and MCB/fuses (both items
supplied by others) must be fi tted to the incoming electrical supply to the mixer. In addition a 30mA
residual current device is strongly recommended to provide extra protection.
Check that the impedance of the earth circuit is safe and operating at the correct value.
The machine must be equipotentially bonded. The earthing screw is situated at the rear
of the machine and is identifi ed by the symbol shown on the right.
Check the earth bonding resistance is less than 0.1Ω and the insulation resistance is greater than 2
MΩ.
10.4 ELECTRICAL CONNECTION.
Refer to the wiring diagram supplied with the mixer and enclosed in the document envelope.
10.5 OPERATOR TRAINING.
Take time to explain the correct operation and cleaning of the Legacy mixer to the users referring to
this manual. Leave this manual with the operator and explain that it is important to use it for further
reference.
11.0 MIXER MAINTENANCE.
A Hobart trained and competent person should carry out serving.
Do not remove any covers or loosen any fi ttings while the mixer is operating.
Ensure the electrical supply has been isolated before attempting to service or move the
mixer.
Disconnect the electrical power to the machine and follow lockout/tagout
procedures.
The electronic drive control is fi tted with high voltage capacitors. Isolate the mixer
from the mains and allow the capacitors to discharge for 5 minutes before removing any covers.
26
11.1 LUBRICATION.
11.1.1 SLIDEWAYS.
Fig. 10
The slideways (Fig. 10) should be lubricated approximately twice a year. To reach these areas, fully
lower the bowl support and remove the apron, which is secured by slotted screws. Wipe a thin coat of
Lubriplate 630AA on the bowl pad area of the bowl supports and on each slideway. Install the apron.
Refer to the recommended spare parts Section 13, page 30 for the lubriplate oil part number.
11.1.2 BOWL LOCKING MECHANISM.
Bowl Locking Mechanism should be lubricated after cleaning. Clean only if sticking or hanging up.
11.1.3 PLANETARY SEAL.
Occasionally, the planetary seal (Fig. 10) may become dry and begin to squeak. To correct this, work a
little lubrication (mineral oil) under the lip of the seal.
27
11.1.4 TRANSMISSION OIL.
Transmission oil should be checked once yearly or
more depending on machine use. To check the oil
level, remove the top cover, which is secured by two
screws. Remove the Transmission Fill Plug (Fig. 11)
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 overfi ll the transmission, as leakage may
result. Contact your local Hobart Service Offi ce for the
recommended transmission oil.
11.2 ADJUSTMENTS.
Fig. 11
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 fl at beater is 1/8" (3 mm); the maximum
clearance between the bottom of the bowl and the ED dough arm is 5/16" (8 mm) for the HL800 Mixer
and 11/16" (17 mm) for the HL1400/HL1400N Mixer.
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 found below.
11.2.2 TO MEASURE THE AGITATOR CLEARANCE.
Pour enough fl 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), briefl y run the mixer at the lowest speed.
Turn off the mixer, disconnect the electrical power supply, and measure the depth of fl 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 (which is secured by slotted screws).
• Adjust the stop screw on left 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 adjustment.
