Item 14 - Exhaust System
Check the exhaust manifold retaining nuts, exhaust flange clamp and other connections for tightness.
Check for proper operation of the exhaust pipe rain cap, if one is used.
Item 15 - Emergency Shutdown
With the engine running at idle speed, check the operation of the emergency shutdown every 700 hours
(20,000 miles). Reset the air shutdown valve in the open position after the check has been made.
Item 16 - Radiator
Inspect the exterior of the radiator core every 700 hours (20,000 miles) and, if necessary, clean it with a quality grease
solvent such as mineral spirits and dry it with compressed air. Do not use fuel oil, kerosene or gasoline. It may be
necessary to clean the radiator more frequently if the engine is being operated in extremely dusty or dirty areas.
Item 17 - Shutter Operation
Check the operation of the shutters and clean the linkage and controls.
Item 18 - Oil Pressure
Under normal operation, oil pressure is noted each time the engine is started. In the event the engine is equipped with
warning lights rather than pressure indicators, the pressure should be checked and recorded every 700 hours (20,000
miles).
