Check Spark Plugs

Service Interval: Every 160 hours

Remove spark plugs, check condition and reset gaps, or replace with new plugs. See Engine Owner’s

Manual.

Change Fuel Filter

Service Interval: As required

A fuel filter is installed in the fuel line between the fuel tank and the engine. Replace when necessary.

Change Hydraulic System

Filter

Service Interval: After the first 250 hours

Every 500 hours/Yearly

(whichever comes first) thereafter

(Every 250 hours/Yearly if using Mobil 1 15W50)

Note: Use only Exmark Part No. 109-4180 for

Summer use above 32°F (0°C) or P/N 1-523541 for

Winter use below 32°F (0°C) (Refer to Transmission section in Specifications for filter specifications).

1. Stop engine, wait for all moving parts to stop, and remove key. Engage parking brake.

2. Carefully clean area around filter. It is important that no dirt or contamination enter hydraulic system.

3. Unscrew filter to remove and allow oil to drain from reservoir.

Important: Before reinstalling new filter, fill it with Exmark Premium Hydro Oil and apply a thin coat of oil on the surface of the rubber seal.

Turn filter clockwise until rubber seal contacts the filter adapter, then tighten the filter an additional

2/3 to 3/4 turn.

4. Fill reservoir as stated in Check Hydraulic Oil

Level.

Maintenance

Exmark Premium Hydro Oil is recommended.

5. Loosen filter 1/2 turn and allow a small amount of oil to leak from the oil filter (this allows air to be purged from the oil filter and supply hose from the hydraulic reservoir). Turn filter clockwise until rubber seal contacts the filter adapter. Then tighten the filter an additional 2/3 to 3/4 turn.

6. Raise the rear of machine up and support with jack stands (or equivalent support) just high enough to allow drive wheels to turn freely.

CAUTION

Raising the mower for service or maintenance relying solely on mechanical or hydraulic jacks could be dangerous. The mechanical or hydraulic jacks may not be enough support or may malfunction allowing the unit to fall, which could cause injury.

Do Not rely solely on mechanical or hydraulic jacks for support. Use adequate jack stands or equivalent support.

7. If either drive wheel does not rotate, one or both of the charge pumps (located on the top of the

main pump as shown in Figure 14) may have lost

their “prime”. Refer to Hydraulic System Air

Purge section.

Note: Do Not change hydraulic system oil (except for what can be drained when changing filter), unless it is felt the oil has been contaminated or been extremely hot.

Changing oil unnecessarily could damage hydraulic system by introducing contaminates into the system.

Hydraulic System Air Purge

Service Interval: As required

Air must be purged from the hydraulic system when any hydraulic components, including oil filter, are removed or any of the hydraulic lines are disconnected.

The critical area for purging air from the hydraulic system is between the oil reservoir and each charge pump located on the top of each variable

displacement pump (Figure 14). Air in other parts of

the hydraulic system will be purged through normal operation once the charge pump is “primed”.

Loosen 1 1/2 turns only

1. Stop engine and wait for all moving parts to stop.

Raise the rear of the machine up onto jack stands high enough to raise the drive wheels off the ground.

2. Check oil level as stated in Check Hydraulic Oil

Level section.

3. Start engine and move throttle control ahead to full throttle position. Move the speed control lever to the middle speed position and place the drive levers in the “drive” position.

If either drive wheel does not rotate, it is possible to assist the purging of the charge pump by carefully rotating the tire in the forward position.

Note: It is necessary to lightly touch the charge pump cap with your hand to check the pump temperature. If the cap is too hot to touch, turn off engine. The pumps may be damaged if the pump becomes too hot.

If either drive wheel still does not rotate continue

with step 4.
