Note: Use only Exmark Part No. 103-2146.

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 Mobil 1 15W-50 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.

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
