Maintenance

CAUTION

Raising the mower deck 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.

3.Remove the pump drive belt.

4.Place a catch pan under the hydro.

5.Carefully clean area around the filters. It is important that no dirt or contamination enter the hydraulic system.
