From safety decals and cab controls through daily inspections, travel and swing operation, periodic maintenance, and breaker and crusher work, the Case CX80 operator manual PDF (OEM ID 87490339 NA) walks the excavator end to end across 196 pages. Maintenance takes up the biggest share of the book. It covers the periodic check list, fuel and lubricant charts by ambient temperature, air bleeding for the pump, cylinders, and swing motor, travel reduction gear oil service, and track shoe tension adjustment. Your monitor display, switch panel, and fuse layout are mapped in the controls section, and the maintenance chapter carries a bolt and nut torque table plus troubleshooting charts. Change the engine oil filter every 500 hours, both air cleaner elements at 1,000, and the pilot and return filter elements at 2,000. A guessed torque figure is how track shoes work loose. Buy it once and the bookmarked, text-searchable file is yours for as long as you run the CX80.
