 | 1. Establish manometres on a highway. |  
 | 2. Check up a tension of a belt of a drive of the compressor. |  
 | 3. Start the engine, leave to work on frequency of rotation of a cranked shaft of 1500 mines-1. |  
 | 4. Check up the compressor on presence of following defects: 
 – The low indication of a manometre, however, not below demanded, and the high indication of a manometre, however, not above the demanded;
 – A metal sound;
 – Leaks from shaft consolidation.
 
 In the presence of any defect it is necessary to repair the compressor.

 | 5. Check up electromagnetic муфту: 
 – Lift the car;
 – Examine press a disk and a rotor on presence on them greasings;
 – Check up the coupling bearing on presence of noise and lubricant leak;
 – By an ohmmeter measure resistance of the coil.
 
 If resistance differs from demanded, replace the coil:
 
 – An additional wire submit pressure from the positive plug of the storage battery on contact of a socket of the coil, thus electromagnetic муфта it should be excited.
 
 If electromagnetic муфта it is not raised, replace the coil.
 Resistance of the coil: 3,11±0,08 the Ohm at 12,8 In and 20°C |  |
