How to use the mixer

NOTE: When reading this chapter refer to the pictures of the control panels given in Chapter Functioning.

Operator Qualification

The machine should be operated only by trained, qualified and authorized personnel who have read and understood the information contained in this manual.

Workstation

The Fig. Workstation shows the work area in which the operator can safely use the machine. The machine control position is in front of the control console from which the operator manages all the processing parameters.

Commissioning

Machine loading
Lift the guard and, according to the recipe, pour the ingredients into the bowl without exceeding the maximum dough mixing capacity. The ingredients can be put in in any order.

Controls adjustment
Set the working times for the first and second speeds of the relevant timing devices.

Operation
Turn the main switch on to energize the power board, lower the safety guard, select the bowl counterclockwise rotation direction (see the arrow) for standard use of the machines and press the button Fig. Controls.

CAUTION
If the machine is stopped to carry out maintenance, there is a residual risk that when the protective grille is opened the spiral will continue to turn by inertia. This risk is not present if the machine is working with a full load. This is because when the grille is opened in this mode, the inertia of the spiral will be annulled by the processed product (dough). Moreover, if the machine is carrying out a complete idle cycle, the spiral will take a few seconds to stop completely because of the force of inertia. In this case the operator must take care when entering the risk zone.
NOTE: Rotate the bowl clockwise (selector 2 Controls) for small quantities of dough.

Standard stopping procedure

Stopping procedure:

1. Make sure the work cycle is finished.
2. Turn the main switch to position 0.

Emergency Stop

Press the EMERGENCY button to stop the machine in an emergency:

• The machine stops.
• The emergency button remains blocked.

Starting the machine again after a manual emergency stop

1. Eliminate the cause of the emergency stop.
2. Release the EMERGENCY button.
3. The machine is now ready to be used again.

Switching off the machine

To switch the machine off:

1. Turn the main switch to position 0.
2. Turn the knife-switch situated upstream from the outside power supply cable to position 0.

Maintenance

IMPORTANT: Repair and maintenance work must be carried out by the Official Technical Service from Combisteel BV or those authorized by them.
IMPORTANT: Before carrying out any maintenance, cleaning, or repair operations on the electrical part of the appliance, the electrical supply must be disconnected at the mains switch and the appliance must be unplugged from the electrical supply. As far as possible, work must be carried out with the machine disconnected and with no voltage. For all operations that could be dangerous the operator must have the possibility of checking that the plug remains always removed from the electrical supply. If the machine halts to carry out maintenance, there is a residual risk when opening spiral protection grille that this will continue to rotate through inertia. This risk does not exist if the machine is working fully loaded, since in this case the inertia of the spiral when opening the grille will be cancelled out by the product being prepared (kneading). Moreover, if the machine is carrying out an empty work cycle, there is the possibility that the spiral, due to inertia, takes a few seconds to come to a complete halt. In this case the operator should take great care when accessing the hazardous area.

When the machine is new

The machine should be tested with a little product so that possible manufacturing residues can be removed before starting the production phase.
