BREAK-IN PROCEDURES During manufacturing only the best possible materials are used and all machined parts are finished to a very high standard. It is still necessary to allow the moving parts to “BREAK-IN” before subjecting the engine to maximum stresses. The future performance and reliability of the engine depends on the care and restraint exercised during its early life. Refer to the following throttle position recommendations. • Keep to these break-in throttle position. Up to 10 hours: Below # throttle Downloaded from www.Manualslib.com manuals search engine
