Servicing
Clean screen ahead of master valve. At the end of
250 hours (or later) replace screen by a ring.
All new engines are delivered with a screen
ahead of the starting air master valve for the
purpose of protecting the valve from piping
scale or other foreign matter. After 50 running
hours the screen must be cleaned or replaced.
It can be finally removed at the end of 250
hours, provided the cleaning solution reveals
no appreciable dirt.
Following major repairs and prolonged engine shut-
down, the screen - if already removed - must be
renewed. The above servicing intervals are then also
to be observed.
