Maintenance
6.Clean around oil fill cap and remove cap. Fill to specified capacity and replace cap.
7.Remove drain hose, close fuel tank, and lower hopper.
8.Use oil recommended in engine owner’s manual. Do Not overfill. Start the engine and check for leaks.
9.Wipe up any spilled oil from engine deck mounting surfaces.
Check Hydraulic Oil Level
Service Interval: Every 40 hours
WARNING
Oil spilled or vented from an overfilled hydraulic reservoir onto the PTO brake band will cause a longer stopping time for the deck and blower rotating components. The deck and blower rotating components can cause serious injury.
•Wait for all moving parts to come to a complete stop before servicing.
•Do Not overfill the hydraulic reservoir. Carefully fill only to the recommended level.
•Replace the brake band if it becomes contaminated with oil.
1.Stop engine and wait for all moving parts to stop. Engage parking brake.
2.Tilt hopper up.
3.Clean area around hydraulic reservoir cap and remove cap. Oil level should be to the top of the baffle inside the tank. If not, add oil. Use only Exmark Premium Hydro oil. Replace hydraulic reservoir cap and tighten until snug. Do Not overtighten. Do Not overfill.
Note: The baffle is labeled “HOT” and “COLD”. The oil level varies with the temperature of the oil. The “HOT” level shows the level of oil when it is at 225°F (107°C). The “COLD” level shows the level of the oil when it is at 75°F (24°C). Fill to the appropriate level depending upon the temperature of the oil. For example: If the oil is about 150°F (65°C), fill to
halfway between the “HOT” and “COLD” levels. If the oil is at room temperature (about 75°F (24°C)), fill only to the “COLD” level. Do Not overfill.
Check Tire Pressures
Service Interval: Every 40 hours
1.Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.
2.Check tire pressure in drive tires.
3.Inflate drive tires to 15 psi (103 kPa).
4.The rear caster tire is
Note: Do Not add any type of tire liner or foam fill material to the tires. Excessive loads created by foam filled tires may cause failures to the hydro drive system, frame, and other components. Foam filling tires will void the warranty.
Check Condition Of Belts
Service Interval: Every 40 hours
1.Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.
2.Tilt hopper up and check pump and PTO drive belts for wear, cracking, or contamination.
3.Belts are spring tensioned and no adjustment is necessary unless belts are replaced. See PTO Belt Replacement and Pump Drive Belt Replacement sections for belt replacement.
Lubricate Grease Fittings
Note: See chart for service intervals.
1.Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.
2.Lubricate fittings with one to two pumps of NGLI grade #2
Refer to the Lubrication Chart for fitting locations and lubrication schedule.
