What is the maintenance schedule for a Bobcat S590?

Interval	Service	Details
Every 10 hours	Lubrication Points	Lubricate with multipurpose lithium based grease. Source: Bobcat OEM service schedule (SS SSL S590 iT4-AZND-EN.pdf).
Every 50 hours	Brake Pads	Check the parking brake, foot pedals, hand controls and steering levers or joysticks for correct operation every 50 hours; repair or adjust as needed. Also check the hydraulic hoses and tubelines for damage and leaks, and the wheel nuts for correct torque, at the same interval.

Every 100 hours	Spark Arrester	Empty the spark chamber every 100 hours. The machine ships with a spark arrester exhaust system that has to be maintained to function; the muffler chamber must be emptied every 100 hours of operation. If the loader is operated on flammable forest, brush or grass cover land a spark arrester may be legally required - check local regulations.
Every 250 hours	Drive Belt	Check for wear or damage. Adjust or replace as needed. Break-in service at first 50 hours; the recurring interval is every 250 hours or 12 months, whichever comes first. Source: Bobcat OEM service schedule (SS SSL S590 iT4-AZND-EN.pdf).

Bobcat S590 items without a fixed hour interval

Coolant Flush: Replace the coolant every 24 months. Time-based rather than hours-based. Check the coolant level cold every 10 hours and add premixed coolant as needed, and clean debris from the radiator, hydraulic fluid cooler, air conditioning condenser and rear grille at the same interval.
Engine Oil Level Check: Check the engine oil level before starting the loader, every 10 hours. The same 10 hour walkaround covers the air filter display panel, the cooling system, draining trapped water from the fuel filter, greasing the lift arm and Bob-Tach pivot pins, and checking the seat belt, seat bar, control interlocks, BICS, horn and tyres. The engine oil and filter change itself is a first-50-hour break-in service and then every 250 hours or 12 months - every 100 hours if operating under severe conditions.
