1. Establish about a coupling pedal a steel ruler and measure height of installation of a pedal of coupling. Press a coupling pedal before emergence of notable resistance and measure a free wheeling of a pedal of coupling. |
| 2. Weaken a lock-nut on the end of a pusher of coupling. |
| 3. Turning a coupling pusher, establish a free wheeling of a pedal of coupling in demanded limits. |
| 4. Tighten a lock-nut. |
| 5. After adjustment of a free wheeling of a pedal of coupling, check height of installation of a pedal. |
| 6. If the height of installation of a pedal of coupling does not correspond to demanded values, weaken a lock-nut and turn a persistent bolt until the demanded height of installation of a pedal of coupling will be established. Tighten a lock-nut. |
