When selecting the best location for the mixer, it is helpful to consider the following:
Which location will save steps for the operator and provide easy access?
Product flow - Is it easy to add ingredients to the bowl? Is the next destination of
the mixed product nearby?
Is there existing electrical service?
Is there easy access for cleaning and service?
rai Will the mixer with its attachments extend into heavy traffic areas?
Will stands or portable equipment used with the mixer be easy to move to and from
this location?
IMPORTANT INFORMATION CONCERNING ELECTRICAL SERVICE
Electrical wiring instructions are found on the Electrical Connections page and wiring diagram in
the Mechanic's Maintenance booklet enclosed with the mixer. If your unit is not provided with a
plug, then the unit is to be fitted with a primary disconnect device that has a contact separation
of at least 3mm in all poles.
CAUTION
Before making electrical connections, check that the specifications on the data plate located
on the mixer agree with those of your electrical service.

Your SRM2O Mixer features a newly updated, 2-part safety guard. The Swing RingTM Safety
Guard is easily removed and installed, as well as dishwasher safe. It conveniently swings
out of the way without having to be removed to place or sample ingredients in the bowl.
Only one side of the guard needs to be open when adding ingredients. You'll find this twopiece design is easy to handle and fits conveniently in your sink or dishwasher. It also provides a clear view of the product throughout the mixing cycle.
This mixer will not operate unless the Swing RingTM Safety Guard is properly engaged.
Metal tabs at the rear of the guard activate twin switches that enable the mixer to run only
when the guard is securely closed. These switches protect against accidental operation of the
mixer when the safety guard is open or removed from the mixer. The mixer will automatically
stop if the guard is opened. Additional switches in the bowl slide mechanism automatically stop
the mixer if the bowl is lowered from the "up" (mixing) position.

To install the Swing RingTM Safety Guard, insert the pointed end of the rod at the rear of the
guard into the lower mounting bracket on the mixer housing. Then insert the top end of the rod
into the upper bracket by aligning the groove in the rod with the slot in the bracket. Press the rod
in and allow it to drop down into position. Repeat this for each of the two sections of the guard.
Swing the two halves of the guard forward. When the guard is properly closed, the top of the
guard will engage magnets embedded in the transmission housing just above, The switches are
now activated and the mixer can be operated.
To remove the guard, simply reverse the installation procedure. Grip the two halves of the
guard and pull it open. Use an upward motion to release each half of the guard from the
bracket on the machine body.
To open the guard for access to the bowl, first turn the mixer off by pushing the red stop
button (Fig.1 [13]). Pull open the two halves of the guard and swing one or both outward. It
is not necessary to remove them, Close the guard to resume mixing operations.
Your Univex Mixer is designed to meet the Cook's and Baker's demand for an efficient, dependable appliance. It should give unfailing performance over a period of years when operated and
maintained according to the instructions contained herein and in the accompanying Mechanic's
Maintenance booklet.
The mixer drives various agitator attachments through a beater head shaft to beat, mix, or
whip liquid, viscous, or dry ingredients. The shaft is driven by a sturdy motor whose power
is transmitted by a rugged, cogged belt and a Continuously Variable Transmission (CVT)
through a gear train and a planetary gear set. The speed of the beater shaft can be varied
from approximately 90 to 365 revolutions per minute (rpm). (See page 13 for part numbers
of various agitators, attachments and accessories.)
The SRM2O Mixer is frequently equipped with a power take-off (PTO) that operates other
attachments, such as slicers, graters and grinders. The PTO speed can be varied from 60 to 240
rpm. Be sure to read and follow any safety instructions provided by the manufacturers of
attachments that you operate on the PTO. The PTO hub should be covered with the PTO cap
provided with your mixer when not in use.
WarningNever put hands, spoons, utensils or other objects into the bowl while the mixer
operating! OCR, web optimization using a watermarked evaluation copy of CVISION PDFCompressor

Place the bowl on the bowl support (Fig.1 1171). The pin at the rear of the bowl must align with
the corresponding slot on the bowl support. Align the holes in the bowl mounting brackets
over the pins on the bowl support and lower the bowl into position.
With the bowl in the "down" position, install the desired agitator by sliding it upward onto the
beater shaft (Fig.1 [1]). Rotate the agitator counter-clockwise until it is engaged.
Safety Note Serious injury may result if the bowl is not positioned properly on the bowl support
using the bowl support pins.
With the bowl secured, add ingredients. Liquids should be added first. The bowl is now ready to
be raised to the "up" (mixing) position by turning the bowl lift handle (Fig.1 [14]) clockwise.
Secure and close the Swing RingTM Safety Guard before proceeding.
shig th Bow Lift
The mixer will not operate unless the bowl is in the "up" position. Raise the bowl by turning the
bowl lift handle (Fig. i [14]) clockwise. To lower the bowl, turn the handle counter-clockwise. It is
necessary to lower the bowl to change the agitator. This also makes the bowl accessible for filling.
Start/Stop Contr&s
The mixer will only start when the Swing RingTM Safety Guard is engaged and the bowl is in
the raised position. To start mixing, push the green start button. For safety and operational
ease, this mixer is equipped with a stop button (Fig.1 [131) that has an oversized, red mushroomstyle cap.
Safety Note Although the motor shuts off instantly when the Swing RingTM Safety Guard is
opened, or the bowl is lowered, or the stop button is pushed, the agitator may not come to
complete rest for several revolutions. Do not put hands or utensils into the bowl or near
the beater shaft until it is fully stopped.
Both the start button and stop button are momentary contact type. They provide low voltage
protection and prevent accidental start-up in the event of a power interruption.

When equipped with a timer, the SRM2O Mixer will not operate unless the timer has been set
to a specified number of minutes or set in the "HOLD" position. To start the mixer, first turn
the timer dial (Fig.1 {8J) to the desired mixing time. Then push the start button (Fig.1 [121). The
mixer will automatically stop when the timer reaches "O". To stop mixing before the timer
reaches "O", push the red stop button.
The timer may be set for up to 15 minutes of mixing, or may be set on the "HOLD" position for
continuous operation. When setting a time of less than 5 minutes, turn the dial beyond 5 minutes
and then return it to the desired time.
Safety Note The mixer will start only when the Swing RingTM Safety Guard is engaged and the
bowl is in the raised position. Do not operate the mixer without the bowl in place.
VarSpeed Cant
A major advantage of Univex mixers is their Continuously Variable Transmission (CVT).
Unlike other mixers, CVI lets you change speed while the mixer is running. Change speed by
moving the speed control lever (Fig.1 [91) to the desired level. The speed indicator (Fig.1 [101)
shows four speeds, Numerous intermediate speeds give the Cook or Baker tremendous flexibility.
Use speed i (slow) for heavy mixtures like pizza, bread or roll dough. (Speed i should also be
used with the Meat and Food Chopper attachment on the power take-off.) For most mixing
tasks, start on speed i and progress to higher speeds as needed. Use high speeds for whipping
cream, beating eggs, and thin batters. To avoid damaging your mixer, follow the speed, vol-
ume limits and attachment recommendations shown in the Table of Mixing Capacities on
page 14.
If you notice any slippage during mixing, the mixer may be overloaded. Reduce the load, or
reduce speed until mixing action is smooth, Refer to the Trouble-Shooting Guide on page 12.
If the mixer jams and the motor stalls, immediately press the stop button. Take necessary steps to
reduce the load. Never put hands in the bowl to clear a jam.
NOTE Always return to speed i before shutting off the mixer. Do not move the speed control
lever when the mixer is not running, because this will cause belts to become loose and the mixer
will not operate properly.
If the mixer has been shut off by the timer, or stop button in speed 2, 3 or 4, follow
these steps to avoid belt slippage or jerky start: Empty the bowl. Set the timer to "HOLD".
Press the start button. As the mixer begins to operate, move the speed control lever back to speed i.
Press the stop button. Return the timer to "0". Your mixer is now ready for its next task.

Using the Ingredients Chute
The ingredients chute provided with your mixer enables you to add ingredients to the bowl
while the mixer is running, and without opening or removing the Swing RingTM Safety Guard.
The chute may be installed on the front or side of either half of the guard. Refer to Fig. 2.
Once the chute is properly installed, it can remain in place permanently, if desired.
Fig. 2 Ingredients Chute Installation
Slide the bottom of the chute between horizontal safety guard rings and engage the
chute onto the safety guard.
Using Smaller Bowl
For maximum flexibility, an alternative 12-quart bowl is available for use on your SRM2O
Mixer. Specially sized agitators must be used. See page 13 for part numbers.
Splash/Extension Ring
A splash/extension ring (Fig. 3[hj) mounted to the bowl helps confine ingredients during the
mixing of certain recipes. This ring should never be used to overload a mixer beyond its
recommended capacity. Consult the Table of Mixing Capacities on page 14 whenever you are
unsure of appropriate loads.

The power take-off hub (Fig. i [5]) accommodates #1 2 tapered attachments, such as a Vegetable
Slicer and Shredder, or a Meat and Food Chopper. The mixer's speed control lever also controls the
PTO drive speed.
Before installing attachments, turn the mixer off. Remove the PTO cap and loosen the thumb
screw (Fig.1 [61) on the PTO hub, Insert the attachment with a slight twist until firmly in
place. Tighten the thumb screw. Be sure to read and follow any safety instructions provided
for attachments that you operate on the PTO.
Safety Notes
When grinding meat, chopper attachments must never run faster than speed i . For vegetables, attachments may run at higher speeds.
Always turn the mixer off to install or remove attachments.
Always return to speed i before shutting off mixer.
Cover the PTO hub with the PTO cap when not in use.
Consistent use of the following procedures will help ensure that your mixer is in
optimum condition.
WarningDisconnect electric power supply before cleaning.
Wash the body of the mixer, the bowl support, and beater shaft with warm water and
mild soap.
Avoid excess water in the area of the safety switches that protrude from the housing where
the Swing RingTM Safety Guard is mounted.
Do not rinse with a hose.
Do not use abrasive pads.
Dry the mixer thoroughly using a soft cloth.
Wash the bowl and beater immediately after use. If egg mixtures or flour batters have been
used, rinse the bowl and beater with cold water before washing with hot water. Wash the
Swing RingTM Safety Guard in the same manner, or in your dishwasher.
Dry bowls, agitators and safety guard thoroughly.

For best long-term performance, operators should follow these simple practices:
Lightly lubricate the beater shaft (Fig.1 [111) after washing. Petro-Gel or equivalent food
grade lubricant should be used.
Do not cover the unit with a plastic bag, as this traps humidity in your mixer.
If the electrical supply cord is damaged, it must be replaced by a special cord or assembly
available from Univex directly or from a Univex service agent.
Do not overload the mixer. Overloading is the # i cause of mixer failure. Follow the
Table ofMixing Capacities on page 14. It may be helpful to post a copy of this table adjacent
to the mixer.
Keep the mixer properly lubricated. Lack of lubrication is the #2 cause of mixer failure.
Key mixer components require lubrication after each 500 hours of operation. (Instructions
on frequency and method of lubricating appear in the enclosed Mechanic's Maintenance
booklet.)
Only change speed with the mixer running. Changing speed with the mixer off will cause
belts to loosen, and the mixer will not turn (see Trouble-Shooting Guide on page 12).
Return to speed i before shutting the mixer off, Use the procedure described on page 8 to
return the mixer to speed i if mixer is shut off in a higher speed.

NOTES: Recommended speeds are for the capacities listed. For larger capacities, reduce speed. Dough capacity,
whether for breads, rolls, pizza, bagels or doughnuts, is based on 12% flour moisture and 70°F (2 1°C)
water temperature. Reduce capacity if cold water is used. If higher gluten flour is used, reduce total
capacity by 10%.
AR% (Absorption Ratio) = the weight of the water divided by the weight of the flour.
The lower the AR%, the stiffer and more difficult the dough is to mix.
AR% below 40% will reduce total capacity.
