 Check of a technical condition Check an axis and the pedal plug on wear existence. Check a coupling pedal on bend and distortion existence. Check a returnable spring on damage or easing existence. Check a pedal platform on damage or wear existence. 
 
 Check pedal height over a floor (from an external surface of a platform of a pedal to a floor) (fig. 3.13) .Nominal size "And": 182,7 mm. 
 
|  | Fig. 3.14. Adjustment scheme педели couplings 
 | 
 If the pedal height over a floor does not correspond to norm, adjust it, as is shown in drawing 3.14 .Bolt adjust pedal height then tighten a lock-nut. 
 
| ATTENTION After adjustment tighten a bolt so that it concerned a pedal emphasis then tighten a lock-nut. | 
 Rotation of a pusher adjust its length on new height of a pedal then fix a pusher a nut. 
 
| ATTENTION At adjustment of height of a pedal watch that the pusher was not displaced towards the main cylinder. | 
 Upon termination of adjustment be convinced that the free wheeling of a pedal of coupling (measured from a surface of a platform of a pedal) is in norm limits. Nominal rate "In": 6–13 mm.

 | 
 If the free wheeling of a pedal of coupling does not correspond to norm, the possible reasons are availability of air in a hydraulic actuator or malfunction of the main cylinder. Pump over a hydraulic actuator and check the main cylinder or coupling (fig. 3.15) .
