It assumes that persons using this manual have been properly trained in and are familiar with the servicing procedures for these products, including the proper use of required tools and safety equipment and the application of appropriate safety practices. Persons untrained or unfamiliar with these procedures or products should not attempt to perform such work.  \nProper maintenance and repair is important to safe, reliable operation of all engines and engine-driven systems. The troubleshooting, testing, maintenance, and repair procedures described in this manual are appropriate for the Briggs & Stratton® engines described herein. Alternative methods or procedures may pose risk to personal safety and the safety and/or reliability of the engine and are not endorsed or recommended by Briggs & Stratton.  \nAll information, illustrations, and specifications contained in this manual were based on the data available at the time of publication. Briggs & Stratton Corporation reserves the right to change, alter, or otherwise improve the product or the product manuals at any time without prior notice.  \nBriggs & Stratton offers two complementary publications to enhance understanding of engine technology, maintenance, and repair. (Neither publication, however, is a substitution for a recognized training program for engine technicians.)  \n• For consumers, Small Engine Care & Repair (p/n 274041) provides a comprehensive overview of how small air-cooled engines work, basic troubleshooting, and step-by-step maintenance procedures.  \n• For engine technicians and consumers alike, an in-depth study of engine theory and operation can be found in the textbook Small Engines (p/n CE8020) .  \nBoth publications can be purchased at BRIGGSandSTRATTON.COM or through a local Authorized Briggs & Stratton Service Dealer.  \nCopyright © 2010 Briggs & Stratton Corporation  \nAll rights reserved.  \nNo part of this manual may be reproduced or transmitted in any form or by any means, electronic or mechanical, including photocopying or recording by any information storage and retrieval system, without prior written permission from Briggs & Stratton Corporation.  \nThis engine repair manual includes the following  \nengine models:  \n• MODEL 430000  \n• MODEL 580000  \nSECTION 1-Safety  \nSECTION 2-Cylinder Heads and Valves  \nSECTION 3-Governor, Timing Gears, and Gear Case  \nSECTION 4-Flywheel and Rear Seal Retainer  \nSECTION 5-Cylinder Block Disassembly  \nSECTION 6-Cylinder Block Inspection and Repair  \nSECTION 7-Crankshaft, Camshaft, and Bearings  \nSECTION 8-Pistons, Rings, and Connecting Rods  \nSECTION 9-Cylinder Block Assembly  \nSECTION 10-Fuel System and Related Components  \nSECTION 11-Ignition, Electrical System  \nSECTION 12-Lubrication System  \nSECTION 13-Cooling System  \nSECTION 14-Engine Specifications  \nSAFETY INFORMATION - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 4  \n1  \n1  \nThis repair manual contains safety information that is designed to:  \n• Make you aware of hazards associated with engines.  \n• Inform you of the risk of injury associated with those hazards.  \n• Tell you how to avoid or reduce the risk of injury.  \nSignal Words in Safety Messages  \n The safety alert symbol is used to identify safety information about hazards that can result in personal injury.  \nA signal word (DANGER, WARNING , or CAUTION) is used with the alert symbol to indicate the likelihood and the potential severity of injury.
