After the first 8 hours
• Check the condition and tension of the alternator belt.
After the first 50 hours
• Change the engine oil and filter.
• Change the transmission-oil filter.
• Change the hydraulic-return filter.
• Check the engine speed (idle and full throttle).
Before each use or daily
• Check the engine-oil level.
• Check the cooling system.
• Check fuel level.
• Check the hydraulic-fluid level.
• Check the torque the wheel-lug nuts.
• Check the tire pressure.
• Grease the bearings, bushings, and pivots (grease them immediately after every
washing regardless of the interval listed).
• Check the air-cleaner-blockage indicator (service the air cleaner earlier if the
air-cleaner indicator shows red; service it more frequently in extremely dirty or
dusty conditions).
• Drain water or other contaminants from the water separator.
• Remove debris from the screen, oil coolers, and radiator (more frequently in dirty
operating conditions).
• Check the safety-interlock system.
• Check the hydraulic lines and hoses for leaks, kinked lines, loose mounting supports,
wear, loose fittings, weather deterioration, and chemical deterioration.
• Check the height-of-cut setting.
• Inspect the flail rotors and blades for damage, cracks, and loose fasteners. Replace
any damaged or cracked parts.
• Check the back guard.
• Verify the blades and rotors are free of debris and rotate/pivot freely.
• Check the front rubber guard.
• Check the cutting unit pivot.
• Check for any unusual vibration of the rotor.
Every 50 hours
• Grease the bearings, bushings, and pivots (grease them immediately after every
washing regardless of the interval listed).
• Inspect the blades for damage and excessive wear.
• Make sure that each blade bolt is torqued to 45 N∙m (33.2 ft-lb).
• Check the blade bolts.
• Check the cutting unit pivot.
• Check for excessive play in the rotor bearings.
• Check the rear-roller adjustment.
• Check the rear-roller scraper wire tension.
Every 100 hours
• Inspect the cooling system hoses.
• Check the condition and tension of the alternator belt.
Every 150 hours
• Change the engine oil and filter.
Every 250 hours
