Note about the screws
The special screws (25/35), can only be removed with a screw driver furnished with a special blade insert. These special blade inserts for the screwdriver can be ordered from the parts department. Because of approval-board requirements and reasons of safety, only the special screws (35) into the base plate must be used to avoid tampering by un-authorized persons.
Note about the PCB Note about the wiring
Attention, charging capacitor on the PCB (36) is charged, use a resistor of 10-50 Ohms to discharge. All connecting cables are provided with self-securing plugs. In order be bent down slightly. These pins must not be deformed or broken off. In case that the plug does not snap in correctly to the connecting contact, a completely new cable must be used. It is not possible to adjust the speed. In case that the number of revolutions does not correspond to the technical data, the device is defective.

Dismantling Remove all supplementary parts from the device and turn the switch to the "0" position. Exchangeable parts assembled in the housing upper part Remove the cover (1) by means of a dismantling fork (already existing for K 1000), see sketch 1. Now, the leg spring (3), the lever (4) and the switching-PCB (5) can be reached. Exchangeable Parts assembled in the housing lower part For the sake of a better dismantling, the parts in the housing upper part must be dismantled. Take off the setting knob (10) and the switch knob (11) to the front. Remove the button (12) and the pressure spring (13) to the front. Place the supporting plate underneath the corresponding coupling shaft by inserting the supporting bolt from the lower side into the small long hole (8 x 3 mm) in the base plate, see sketch 2. Now, cleave the coupling (6/7) with an appropriate tool (e.g. screwdriver size 4 - 5.5 mm) in the center of the top and remove it from the shaft. Unscrew the screws (35) in the base (33) and remove the base. The completely assembled carrier with motor can be removed from the housing. All remaining parts which are as well shown in the exploded drawing can be dismantled and exchanged. Before dismantling the gear wheels with shafts (26/28), the tension roller (27) and the motor (18) the toothed belt (29) must be removed. The safety lock (8) is inserted in the housing by means of two snap-in pins. Reassembly To be performed in reversed order. However, attention must be paid to the following points: After reassembling the gear wheels (26/28), the tension roller (27) and the motor (18) the toothed belt must be orderly positioned and the tension must be reapplied.

Attention must be paid to the reassembling position of the motor and to the cable connection (+/-), see sketch 3. Tension of the toothed belt: Slightly loosen the motor securing screws and displace the motor (18) on the carrier. If the toothed belt is correctly tensioned, the motor securing screws (25) will be tied. Please refer to sketch 4 for the tension value of the toothed belt. The both washers (22) must be attached to the shafts. The O-rings (15) must be inserted into the housing. Attach all dampers (23) for the carrier. Insert the completely reassembled carrier into the housing (9). Connect the leads to the switch-PCB (36), see sketch 3. Insert the switch-PCB into the guides of the base plate and the switch cams (37), see sketch 6. Attach the base (33) and the rubber feet (34). Place the supporting plate underneath the corresponding coupling shaft. Then, press the coupling onto the shaft by slightly tapping against the embossing spike. The axial free space of the coupling shafts must be 0.4 mm - 0.6 mm, see sketch 5 (symbolic illustration). A smaller or larger axial free space may cause a defect of the appliance. Insert the setting knob (10), and make sure that the potentiometer for the setting knob axis is placed in the correct position. Insert the spring (14) into the housing front. Assemble the pressure spring (13), the button (12) and the switch knob (11), see sketch 6. Connect the leads to the switching-PCB (5) and insert the switching-PCB into the housing upper part. Insert the lever (4) and the leg spring (3), see sketch 7 (symbolic illustration). Attach the cover (1) to the housing upper part until it snaps in.

Function Check
Check the appliance in all switching positions and, if necessary, attach the available supplementary parts. Check the security locks with and without the complete bowl resp. mixer.
