Installation

PERFORMANCE ORDER
1. Carefully clear the demountable planes of a collector and a head of cylinders.
2. Check existence on a collector of cracks, a buckling of the plane and other damages. As a rule, cracks and a buckling are observed on a surface of a prileganiye of laying, round openings under hairpins. In this case the collector is ground or changes.
3. Establish on a collector new laying which should be turned by a graphite surface to a head of cylinders.
