| 1. For motor-reducer dismantling turn away screws of fastening of a cover of 1 reducer and remove it together with the panel 2. |
| 2. Then turn away screws of fastening of a cover 16 to the case 7 electric motors and separate them. |
| 3. Take out an anchor 8 electric motors. |
| 4. To remove a gear wheel 3 reducers, turn away a nut of fastening of a crank 9, remove a lock ring from an axis and take out from the case an axis with a gear wheel and washers. |
| 5. After dismantling blow internal cavities of the electric motor the compressed air for removal of adjournment of a coal dust and check up a condition of brushes and a collector. |
| 6. Brushes should freely, without jammings to move in щеткодержателях, and springs should be whole and have sufficient elasticity. |
| 7. A collector smooth out a fine-grained grinding skin, and then wipe the pure rag slightly greased with technical vaseline. If the collector has strongly scorched or is worn out, it is better to replace a motor-reducer new. |
| 8. Check up, whether there are no jamming traces on necks of a shaft of an anchor. If necessary smooth out their fine-grained grinding skin. |
| 9. At assemblage take away brushes from a collector not to break them and not on-harm their edges, and an anchor into the case insert with extra care, avoiding anchor blows about poles not to break them. |
| 10. After assemblage, for centering of bearings, knock with a wooden hammer on the motor-reducer case, and then check up it at the stand. |
