CONTROLS
All models are furnished with an On-Off toggle switch which controls power to the mixer.
The Bowl Guard must be in position or the mixer will not operate. Refer to page 6.
If the Bowl Support is not all the way up, the mixer will not operate unless the On-Off switch is held inthe up position.
The TIMER (if equipped) is used in conjunction with the On-Off switch for timed mixing operations andwill stop the mixer when the desired time has elapsed.
With the timer set on HOLD, the mixer will run until the On-Off switch is turned to Off.
The GEAR SHIFT LEVER (Fig. 1) is used to change speeds. Always stop the mixer before changingspeeds. To change speeds, turn the switch Off, move the gear shift lever to the desired speed, andturn the switch back On.
Speed 1 (Low) — This speed is for heavy mixtures such as bread dough, heavy batters, andpotatoes.
Speed 2 (Medium) —This speed is for light dough which must rise quickly, cake batters, and somewhipping operations.
Speed 3 (High) — This is a fast speed for light work such as whipping cream, beating eggs, andmixing thin batters.
The BOWL LIFT HANDLE (Fig. 1) is used to raise and lower the bowl. To raise the bowl, rotate thehandle upward; rotating the handle downward lowers the bowl.
MIXING
This section explains operation of the mixer and how to install bowls, agitators, and attachments. Aseparate Use and Applications Handbook is provided with the mixer which contains information onmixing procedures and outlines specific uses for agitators, attachments, and accessories.
Bowl
New mixer bowls and agitators (beaters, whips, and dough arms) should be thoroughly washed withhot water and a mild soap solution, rinsed with either a mild soda or vinegar solution, and thoroughlyrinsed with clear water BEFORE being put into service. This cleaning procedure should also befollowed for bowls and agitators before whipping egg whites or whole eggs.
The bowl must be installed before the agitator. To install the bowl, fully lower the bowl support (Fig. 1).Position the bowl so the alignment bracket on the back of the bowl is in the bowl retainer and thealignment pins (Fig. 1) on the front of the bowl support fit in the holes on the sides of the bowl. Lockthe bowl in place by rotating the bowl clamps (Fig. 1) over the ears of the bowl.
Agitator
To install an agitator (Fig. 1), the bowl must be installed and fully lowered. Place the agitator in the bowl,push it up on the agitator shaft, and turn it clockwise to seat the shaft pin in the slot of the agitator shank.
