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.

Turn filter clockwise until rubber seal contacts the filter adapter, then tighten the filter an additional 2/3 to 3/4 turn.
