• At service interval (see chart).
Always replace the hydraulic filter when you replace the hydraulic fluid.
Change The Hydraulic Oil

c After the oil has drained, install the hose and fill the tank with hydraulic fluid.
d Start the engine and operate all the mower functions for 5 minutes to remove air from the system.
e When all air is removed from the hydraulic-fluid, check the level, add hydraulic fluid to the tank to the
recommended level.

fill the hydraulic tank, use only clean oil. The hydraulic oil must go through a 25micron filter before the
oil enters the tank.
