Part of the Case Operator Manuals.
All 216 pages of this Case CS68, CS68a, and CS75a Operator Manual (OEM #Sva 6-25510) are built around one goal: keeping your tractor running the way Case engineered it. Inside, you get a detailed instrument panel walkthrough covering every indicator lamp and warning light, a full section on rear and front PTO shaft setup and operation, and three-point linkage procedures from quick-action coupling to upper link adjustment. Open to the maintenance section and you'll find tyre pressure tables, complete fluid capacities, and a lubrication schedule organized by the hour. Change the engine oil filter at 250 hours, the fuel filter at 1000 hours, and keep your alternator belt deflection to 5-10 mm. Your machine is paid to work, not sit idle. Grab the bookmarked PDF, search any spec by keyword, and get back in the seat.

Case CS68, CS68A, CS75A Common Problems This Manual Covers
Case CS68 engine temperature warning light on during heavy dusty field work
Stop work and let the engine idle to cool. Clean debris from radiator fins with compressed air; dust accumulation blocks airflow and drives coolant temps up fast in field conditions. Inspect the alternator belt deflection at page 171, which should measure 5 to 10 mm. Review the maintenance schedule at page 150 for radiator cleaning frequency.
Manual Section: Engine MaintenanceBattery charging indicator light on during operation, alternator output failure suspected p. 31
Stop the engine per the warning at page 31. Inspect the alternator belt for slippage or breakage; correct deflection is 5 to 10 mm (page 171). Clean battery terminals and check cable connections for looseness. The battery is rated 12 Volt, 90 Ah, 420 A (page 202); test charge level before attempting a restart.
Manual Section: Battery Charging WarningAir filter maintenance indicator lit, engine sluggish and down on power under load p. 31
Check the air filter maintenance indicator description on page 31 to confirm action required. Remove and clean the main air filter cartridge immediately. Replace the main cartridge at least once per year (page 156), regardless of indicator status. Replace the safety cartridge after the main unit has been cleaned 5 times, or every 2 years.
Manual Section: Air Filter Maintenance IndicatorEngine oil pressure warning light on, oil pressure critically low p. 30
Stop the engine at once. Pull the dipstick and verify oil level; total engine capacity is 10.0 liters (page 151). Inspect around the filter housing and drain plug for visible leaks before adding oil. Change the oil filter every 250 operating hours or at least once per year (page 156). Do not restart until the cause is confirmed.
Manual Section: Engine Oil Pressure WarningHydraulic hose connections weeping or leaking fluid after short field operation p. 183
Depressurize the system, then inspect every hose fitting and connection for damage or looseness. Check the hydraulic oil level; the system holds 15 liters (page 151). Replace any leaking hose with original spare parts only (page 183); do not patch or reuse a damaged hydraulic hose. Identify the root cause before refilling and restarting.
Manual Section: Hydraulics MaintenanceClutch slipping or gears difficult to engage when working under heavy load p. 173
Measure clutch pedal free play at the pedal tip; correct range is 20 to 30 mm (page 173). Adjust if the measurement falls outside that range. Verify engine/transmission oil type is grade E, E1, or E2 (page 151) and check that the fill level is correct per the capacities table at page 151.
Manual Section: Engine MaintenanceFrequently Asked Questions
What are the replacement specifications for Hydraulic hose?
When hydraulic hoses are defective, they must be replaced immediately with original spare parts. This ensures proper function and safety of the hydraulic system.
How do you fix case CS68 engine temperature warning light on during heavy dusty field work?
Stop work and let the engine idle to cool. Clean debris from radiator fins with compressed air; dust accumulation blocks airflow and drives coolant temps up fast in field conditions. Inspect the alternator belt deflection at page 171, which should measure 5 to 10 mm. Review the maintenance schedule at page 150 for radiator cleaning frequency.
How do you fix battery charging indicator light on during operation, alternator output failure suspected?
