| Cont'd.{John DeLooze - Company Secretary} -3- (7) The final adjustment refers to that of the gap of the lower contacts. This should be adjusted to be .030" when the relay lever is in its off position (as previously adjusted by top contact). (8) Having made these various adjustments, all gaps should be checked over and should be found reasonably to agree with the tables on the sheets herewith. (9) The above refers solely to the adjustments in regard to gap etc. distances and so far no mention has been made of the magnitude of the forces involved. A check on the correctness of these is contained in the Specification of Production Inspection and Test. EFC. | ||
