7.4.10. Speedometer check
Adjust pressure of air in tires to nominal rate.
Place the car on running drums and substitute an emphasis under back wheels.
On purpose to avoid shift of forward wheels here and there, put on towing hooks of the car two extensions which ends reliably fix on anchor plates.
For prevention of movement of the car forward a back towing hook put on reliably fixed chain or a cable.
Check a scale of measurements at the high-speed stand and its compliance to nominal rates of speed.
Do not release sharply a coupling pedal. Do not allow sharp increase/decrease in speed in the course of test.
