Part of the Case IH Operator Manuals.
All 190 pages of this Case 400 Series Operator Manual are the factory reference for operating and maintaining your tractors. Inside: a full controls and instrument guide and a complete lubrication section mapping every grease point across engine, transmission, rear axle, and PTO. You also get a tiered maintenance schedule stepping through 60-, 120-, 240-, 500-, and 1000-hour intervals, plus a Service Suggestions chapter tackling the most common field problems: engine won’t start, overheating, and low oil pressure. Set rear tire pressure to 14 pounds on 13-inch tires and 16 pounds on 14- through 18-inch sizes; the cooling system relief cap holds at 4 lbs. Your machine won’t tell you what’s wrong. This manual will.
