Unpacking
Unpack the mixer immediately after receipt. Please inspect the mixer to ensure no damage and all parts i.e. Bowl, Beater, Whisk & Dough Hook have been provided. If the machine is found to be damaged, keep all the packaging material and contact us immediately or contact your source of the equipment. Never attempt to operate the machine with damaged parts. Report any deficiencies to the dealer that supplied the machine.
You should receive with your mixer:

1 x Beater
1 x Whisk
1 x Dough Hook
If any of the above items were not received with your mixer, please refer to page 13 for contact details and inform us immediately for replacements.
Before using the mixer please read this manual thoroughly. Do not proceed with any installation nor operation if you have any questions or do not understand anything within this manual. Please see contact details on page 13 for assistance.
Location
Select a location for the machine keeping these points in mind:

• Counter must be level – It is recommended that the machine is level from front to back and from side to side. This will ensure the greatest stability.
• Easy access for cleaning, maintenance and servicing
• Clearance for operating controls, installing and removing attachments and bowl
• Sufficient space for adding ingredients during mixing
• The surface must be able to support a load of 30kgs
• The rear ventilation outlet of the mixer must not be blocked.

Ambient Conditions

• The minimum requirement for all electrical equipment’s correct operation is an air temperature of between +5 and +40.
• Electrical equipment operates correctly when the relative humidity does not exceed 95% at a maximum temperature of +40.
• Electrical equipment operates correctly at altitude up to 1000m.
• Electrical equipment is designed to withstand and be protected against the effects of transportation, and storage temperature within a range of -25 to +55 and for short periods not exceeding 24h at up to +70.

Electrical Connection

• Before connecting the mixer to an electrical supply, please read the specifications on the rating plate to ensure that they comply with those of the electrical supply.
• The machine works off 220/240V 50Hz 1 phase supply and comes fitted with a 3-pin 13amp fused plug.
• An electrical supply should be available within the reach of the included power cord. DO NOT use extension cords to connect the machine’s power cord to the electrical supply. The low AMP supply could damage the mixer or cause a fire.
• All wiring connections must be checked and tight.

Once the electrical connection has been made, the machine is ready for use.
Fitting the Bowl

Operation

NOTE: Install the bowl BEFORE attaching the agitator.

1. Lower the bowl lift handle anti-clockwise and down to its resting position.
2. Lift the bowl by the handles and slowly position the locking pin located at the rear of the bowl into the hole in the middle rear of the cradle.
3. Lower the bowl onto the pins located on either side of the bowl cradle.

Bowl Lift & Guard
Move the bowl lift handle anti-clockwise to lower the bowl. It is necessary to lower the bowl to change the tools, and to provide better access for filling and emptying the bowl. To raise the bowl, move the bowl lift handle clockwise until it hits the upper stops.
The bowl cradle and guard are electrically interlocked so that the mixer will only operate when the bowl is in the raised position. In addition to this the bowl safety guard must be locked by rotating into position (left to right) and the guard is locked in place. This ensures total user safety at all times.
Once the guard has been opened and the bowl lowered the mixer can only be restarted by pressing the start button.
During operation additional ingredients can be added via the ingredients chute located on the righthand side of the bowl guard.
Tool Selection
The beater, whisk and dough hook are meant for the work implied by their names. Do not use the beater for dough making or the whisk for anything other than whisking, aerating or mixing light mixtures. These are the typical uses for each of the tools supplied:

| Whisk
Light mixes such as whipped cream, mayonnaise, egg whites, pancakes and soufflés
---|---
| Beater
Firm mixes such as light pastry, cakes, biscuits, icing, fillings and mashed vegetables
| Dough
Hook Heavy mixes such as dough and pastry

Fitting Attachments
NOTE: Install the bowl BEFORE attaching the mixing tool.
NOTE: It is easier to install the attachment prior to adding ingredients into the bowl.
Open the bowl guard and lower the bowl.
Slide the attachment slowly upwards onto the planetary shaft, fitting the shaft pin through the slot in the attachment. (Figure A)
Rotate the attachment clockwise to secure it onto the planetary shaft.
NOTE: Attachments should always rotate in a clockwise direction around the bowl. If an attachment is moving counter-clockwise please contact a licensed electrician immediately to remedy incorrect wiring.
New mixers, bowls and agitators (beaters, whisks and dough hooks) should be thoroughly washed with hot water and mild soap solution and thoroughly rinsed with clean water before being used for the first time.

• Before you can start the machine, you will have to lift the bowl and close the perspex safety guard.

• Select time required if using the timer.

• Press on button to start the machine.

• The speed can be adjusted by pressing the up and down arrows on the panel.
  – Number 1 is the slowest speed and number 5 is the highest speed.
  – The speed selected depends largely on the quantity and consistency of the product. Slow Speed
  is for heavy mixtures such as dough, biscuits, etc. and High Speed is for fast, light work, such as whipping cream, beating eggs, and mixing thin substances.
  – It is recommended that mixing is always started at the lowest speed and progressively increased to the desired setting.
  Speed 1 ­ For slow beating, mashing and kneading yeast dough.
  Speed 2 ­ For mixing cookie and cake batters.
  Speed 3 ­ For beating, creaming and medium fast whipping.
  Speed 4 ­ For whipping heavy cream, egg whites and boiled frostings.
  Speed 5 ­ For whipping small amounts of heavy cream and egg whites.

• Never place your hand or any kitchen utensil in the bowl whilst the mixer is in operation.

• Never operate this machine with safety covers removed or with safety switches inoperative.

• When mixing is complete, turn off the machine and lower the bowl by lift handle/lever then take off the attachment.

• Then take out the bowl together with attachment.

• Finally take out the mixed ingredients.

• Please follow the capacity chart on the following page. Overloading or not following the chart will damage the mixer and void the warranty.

Recommended Mixing Capacities

Thin Pizza Dough, Pasta, Basic Egg Noodle

(40% AR) 5 min max mix time

| 0.8 kg| | |  1st only
Medium Pizza Dough (50% AR)| 1.4 kg| | | 1st only
Thick Pizza Dough (60% AR)| 0.9 kg| | | 1st only
Raised Donut Dough (65% AR)| 0.8 kg| | | 1st & 2nd
Whole Wheat Dough (70% AR)| 1 kg| | | 1st & 2nd

Mixing Heavy Dough
The moisture content of heavy dough is a critical factor when selecting the correct mixing speed. You should never use 2nd speed when mixing heavy dough with an Absorption Ratio (AR) of 50% or less.
To determine the Absorption Ratio (AR) of a product, divide the water weight by the flour weight.
Example: Calculate the Absorption Ratio of a mixture containing 50g of water and 100g of flour. 5 ÷ 10 = 0.50 = 50 % = AR

• If high gluten flour is used, reduce above dough batch size by 10 %
• Capacities listed are based on flour at room temperature and water at 20°C. If using chilled flour, water below 20°C, or ice, reduce batch size by 10%
