5 MAINTENANCE AND LUBRICATION
5.6 HYDRAULIC SYSTEM __________________________________________________
Drain and replace the hydraulic oil after:
• Component failure
• Water in the hydraulic fluid
• The hydraulic fluid has been contaminated.
• The hydraulic fluid has a bad smell.
• At service interval (see chart).
Always replace the hydraulic filter when you replace the hydraulic fluid.
Change The Hydraulic Oil
a Clean the area around the oil cap to prevent dirt entering the hydraulic system.
b Remove the hose (A) from the bottom of the tank.
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.
IMPORTANT
If you open any hydraulic line, you need to fill the circuit with oil before the circuit is used. When you
fill the hydraulic tank, use only clean oil. The hydraulic oil must go through a 25micron filter before the
oil enters the tank.
CAUTION
Hydraulic Fluid Can Damage Your Skin. Use the applicable safety equipment. If Hydraulic Fluid
Touches The Skin, Clean The Area Immediately.
CAUTION
Discard Used Hydraulic Oil As Shown In Local Safety Regulations.
