Check Auxiliary Hydraulic Oil Level

Maintenance

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 Exmark Premium Hydro oil. Replace hydraulic reservoir cap and tighten until snug. Do Not overtighten.

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.

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.

3.Tilt the seat forward.

4.Locate the auxiliary hydraulic power unit reservoir (see Figure 9).

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 Exmark Premium Hydro oil. Replace reservoir plug and tighten until snug. Do Not overtighten.

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.

Bar lug drive tires should be inflated to 9 psi (62 kpa).

Turf drive tires should be inflated to 13 psi (90 kpa).

3.The rear caster tires are semi-pneumatic and Do Not need to be inflated.

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.Check pump and PTO drive belts.

3.Belts are spring tensioned and no adjustment is necessary. See Pump Drive Belt Tension and Replacement sections in Adjustments.

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 multi-purpose gun grease.

Refer to the following chart for fitting locations and lubrication schedule.
