Maintenance
5.Replace the oil filter every other oil change. Clean around oil filter and unscrew filter to remove. Before reinstalling new filter, apply a thin coating of oil on the surface of the rubber seal. Turn filter clockwise until rubber seal contacts the filter adapter then tighten filter an additional 2/3 to 3/4 turn.
6.Clean around oil fill cap and remove cap. Fill to specified capacity and replace cap.
7.Use oil recommended in engine owner’s manual. Do Not overfill. Start the engine and check for leaks.
3.Tilt the seat forward.
4.Locate the auxiliary hydraulic power unit reservoir (see Figure 9).
Check Hydraulic Oil Level
Service Interval: Every 40 hours
1.Stop engine and wait for all moving parts to stop. Engage parking brake.
2.Tilt seat 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 Mobil 1
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.
Check Auxiliary Hydraulic Oil Level
Service Interval: As required
Note: Check the auxiliary hydraulic oil level if there is evidence of a leak or the hydraulic cylinder does not perform normally.
1.Retract the hydraulic cylinder.
2.Stop engine and wait for all moving parts to stop.

1.Auxiliary hydraulic reservoir plug
5.Clean area around the reservoir plug and remove. Oil level should be up to the reservoir plug hole. If not, add oil. Use only Mobil 1
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.
•For 23HP Kohler Units: The drive tires should be inflated to 13 psi (90 kpa).
•For 27HP Kohler & 31HP Briggs & Stratton Units: The drive tires should be inflated to 9 psi (62 kpa).
3.The rear caster tire(s) 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.
