| 1. To turn the distributor roller so that mobile contact rose on a ledge of a cam of the roller. Thus the gap between contacts will be maximum. |
| 2. To measure shchupy a gap between contacts 7 and 8 (see fig. Ignition distributor). It should be equal 0,4 mm. Shchup should pass between contacts to hardly appreciable effort, by no means ωσο should not move apart contacts. |
| 3. If the gap differs from specified, to adjust it. For this purpose to weaken screws of fastening of contact 8, to insert a screw-driver into a groove of contact 8 and, turning it and by that taking away or bringing contact 8 to contact 7, to adjust a gap. |
| 4. At UZSK or gap adjustment between contacts the corner of an advancing of ignition therefore after adjustment of UZSK or a gap it is necessary to adjust a corner of an advancing of ignition is broken. |
