Signs «» (advancing) and «–» (delay), put on a scale of the oktan-proof-reader, specify a direction of its rotation.

PERFORMANCE ORDER

2. At movement on equal road on direct transfer with a speed of 50 km/h sharply press an accelerator pedal. If thus there is an insignificant and short-term detonation the corner of an advancing of ignition is established correctly.
3. At a strong detonation (early ignition) ослабьте a nut 1 also turn the case 2 on 0,5–1 division clockwise (on «–»). In case of absence of a detonation (later ignition) turn the case 2 on 0,5–1 division counter-clockwise (on «»).
