Position the machine on level ground.
Stop the engine.
Release pressure in the hydraulic system. Refer to Testing and Adjusting, "System Pressure - Release".
Attach 311-1362 Vacuum Cap onto the hydraulic tank. Attach an air supply hose onto the assembly. Apply 276 to 414 kPa (40 to 60 psi). This procedure will pull a vacuum on the hydraulic system.
