  2. Advertisement fixing bots, located on the top of the unit under three plastic plugs.
  3. Remove the upper part of the body and get a plastic pole.
  4. Unscrew the lower fixing bolts.
  5. Prozvonit input filter capacitor.
  6. Check the operation of the thyristor: voltage level at the input-output must be equal 220 AT.
  7. inspect gearbox, drive shaft and electrically.
  8. Check the action of the juicer, leading disk and a mixer nozzle.

  • nozzle broke for a food processor, or their attachment

Faulty elements, responsible for fixing attachments, - problem, relevant for 90% such equipment. It can be caused by frequent rubbing hard cheese, when there is a great pressure on the axle, plastic deformation and fracture are.

  • Burnout trays and resistance in the electronic board

The causes of failures can be a voltage fluctuations or long life. The fact, electrolytic capacitors dry out with time. Will help solve the problem desoldering bloated capacitor and the installation of a new, similar volume.

  • Premature wear elements

Pinion devices designed to 4 year of use. But as a result of overloading of equipment, grinding solid, frozen products details can fail much sooner.

  • rheostat

In case of breakage of a rheostat starts malfunctioning speeds, when the speed change occurs is unstable, jerkily.

  • Zatuplivanie knives

Sharpening knives - quite a complicated process, to which must be approached with extreme caution. To achieve a good result can be attributed to the nearest service processor, where they can quickly and cost-sharpening blades.

Self Natochka can use the sharpening stone. We must act carefully, Any wrong move - and the knife will Dumber, or it broke off a piece. Sharpening the blade can be rough sandpaper. But in this case the special skill and ability required in order to achieve a good result.
