Carefully unbolt the mixer from the pallet using a wrench socket.

Location

Select a location for the machine with a minimum of 0.6m space around the machine for operating, cleaning and servicing.
Allow working space on the handwheel side as all maintenance can be handled from this side, the top and the front.
Position the machine in its proper working position. The machine must be installed on a flat, solid and dry floor.
The surface must be able to support a load of 660kgs
It is recommended that the machine is level from front to back and from side to side. This will ensure the greatest stability. The machined edge on the top of the transmission case makes an excellent surface for levelling.
The rear ventilation outlet of the mixer must not be blocked
The mixer should be bolted down into position using all four holes located in the legs.

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 mixer should be fitted to a commando or preferably a switched isolator, capable of supporting an electrical load of 32amps, which is fused with a C or D rated breaker.
Electrical connection should be made by a qualified service technician who will observe all applicable safety codes.
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.
The technician should install an over-current protection device (e.g. fuse or NFB) or Residual Current Device (GFCI) to prevent a current fault risk.
Ensure that an isolating switch is fitted within 2m of the machine.
All wiring connections must be checked and tight.

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℃.

Hard Wiring

The mixer can be hardwired into a switched socket which isolates all poles and has a minimum contact clearance of 3mm. It should be located close to the mixer for use in an emergency and to facilitate servicing.
The machine must be incorporated into a potential equalization system.
The leakage current for this appliance is no greater than 1 mA/KW.
If the electrical supply cable to the machine becomes damaged, it must be replaced by the same specification or higher and suitable for the mixer’s motor load.
The ground wire is fixed to the machine and this connection must be kept intact.
CAUTION: The mixer MUST be grounded.

3 Phase Connection

The 3-phase machine works off 380/415V 50Hz 3 phase supply and comes fitted with:
- Three line wires: L1 (brown), L2 (black) and L3 (blue).
- Green: Earth
- There is no Neutral
If you have a 3-phase mixer, when it is in position and connected, please make sure that the shaft goes clockwise. (Same direction as the arrow sticker that located on the front of the mixer). If the shaft goes counter-clockwise, please exchange the position of 2 of the phase wires.
The mixer should be hardwired into a switched socket (see page 6).

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

Operation

Fitting the Bowl
NOTE: Install the bowl BEFORE attaching the agitator.

Rotate the bowl lift handle anti-clockwise to its resting position.
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. (Figure A)
Lower the bowl onto the pins located on either side of the bowl cradle.
Once the bowl is in position, secure it by pulling each bowl clamp forward until the bowl is locked tight. (Figure B)

Bowl Lift & Guard

To raise and lower the bowl you can either use the bowl power lift facility by pressing the buttons on the control panel or rotate the bowl lift handle; anti-clockwise to lower the bowl or clockwise to raise the bowl until it hits the upper stops.
It is necessary to lower the bowl to change the tools, and to provide better access for filling and emptying the bowl.
The bowl cradle and guard are electrically interlocked so that the mixer will only operate when the bowl is in the raised position and the guard is locked in place. This always ensures total user safety.
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 right-hand 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:

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.

Operation

Before you can start the machine, you will have to lift the bowl and close the safety guard.
Place the motor speed shift switch and gear selector handle to desired speed.
For non-timed operation, set timer switch to ‘non-timer’ position.
For timed operation, set time for up to 30 minutes on the timer selection dial, then set the timer switch to ‘timer’ position.
Press on button to start the machine.
The machine must always be stopped before changing speeds. Failure to do so may damage the gears or other parts and will void the warranty.
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 by turning ‘Motor speed shift switch’ to ‘off’ position and press ‘stop’ button’, 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.
In an emergency always use the red emergency stop button to stop the mixer.

Speed Selection
To change speeds, first turn off the motor by turning ‘Motor Speed Shift Switch’ to ‘off’ position, then move the gear selector handle to the desired speed, then turn the ‘Motor Speed Shift Switch’ to the desired speed before restarting the mixer by pressing the start button.
Speed selection is made by ‘Motor Speed Shift Switch’ and ‘Gear Selector Handle’ with the number on the control panel.

1st Speed: Set ‘Motor Speed Shift’ to low speed, and set ‘Gear Selector Handle’ up to ‘1 Low Speed’
2nd Speed: Set ‘Motor Speed Shift’ to high speed, and set ‘Gear Selector Handle’ up to ‘2 High Speed’
3rd Speed: Set ‘Motor Speed Shift’ to low speed, and set ‘Gear Selector Handle’ down to ‘3 Low Speed’
4th Speed: Set ‘Motor Speed Shift’ to high speed, and set ‘Gear Selector Handle’ down to ‘4 Low Speed’
1st Speed (low): for heavy mixtures such as bread dough, heavy batters, biscuits, potatoes etc.
2nd Speed (medium-low): for mixing cake batter, mashing potatoes and for developing dough.
3rd Speed (medium-high): for incorporating the maximum amount of air into light batches, the whip is used for whipping cream, beating egg whites, mixing light icings, meringues and whipping operations.
4th Speed (high): for fast, light work, accelerated incorporation of the maximum amount of air into light batches, similar to 3rd speed.

The speed selected depends largely on the quantity and consistency of the product. It is recommended that mixing is always started at the lowest speed and progressively increased to the desired setting. The moisture content of heavy dough is a critical factor when selecting proper mixing speed. You should never use 2nd gear when mixing heavy dough with an absorption ratio (AR) of 50% or less.
The below table shows the recommended speeds for the range of tools.

Recommended Mixing Capacities

Never use 2nd speed when mixing dough
If high gluten flour is used, reduce 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%
The Absorption Ratio (AR) of a product is calculated by dividing the water weight by the flour weight, e.g. to calculate the AR of a mixture containing 50g of water and 100g of flour: 5 ÷ 10 = 0.50 = 50% AR.

Cleaning Instructions

ALWAYS disconnect from the power source when cleaning or servicing this machine.
ALWAYS remove the attachment/s after each batch. If not, the attachment/s can become stuck on the shaft and difficult to remove.
NEVER attempt to clean this machine while it is in motion, serious injury could result.
