Operating techniques outlined in this manual are basic to assist with developing the skills and techniques required to operate the engine more efficiently and economically. Skill and techniques develop as the pilot gains knowledge of the engine and its capabilities.The operation section is a reference for experienced pilots, and photographs and illustrations guide the new pilot through correct procedures of inspecting, starting, operating and stopping the engine. This section also includes a discussion of gauges, indicators, features and controls.Maintenance
The maintenance section is a guide to engine care. Items in the Maintenance Schedule are referenced to detailed instructions that follow. The instructions and procedures are grouped by fuel consumption, service hours and/or calendar time maintenance intervals.Use fuel consumption first to determine intervals. Calendar intervals shown (daily, annually, etc.) may be used instead of service meter intervals if they provide more convenient schedules and approximate the indicated service meter reading.Recommended service should always be performed at the fuel consumption interval first. The actual operating environment of the engine also governs the maintenance schedule. Therefore, under extremely severe or freezing cold operating conditions, more frequent lubrication and maintenance than is specified in the Maintenance Schedule may be necessary.Maintenance Intervals
Perform maintenance on items at multiples of the original requirement. Each level and/or individual items in each level should be shifted ahead or back depending upon your specific maintenance practices, operation and application. We recommend that the maintenance schedules be reproduced and displayed near the engine as a convenient reminder. We also recommend that a maintenance record be maintained as part of the engine's permanent record.See the Maintenance Records section in this manual for information regarding documents that are generally accepted as proof of maintenance or repair. Your authorized Caterpillar engine dealer can assist you in tailoring your Maintenance Schedule to meet the needs of your operating environment.Overhaul
