5.12HYDRAULIC SYSTEM, PURGING

After replacing or repairing hydraulic system components, one or both of the wheel drives may not pull properly. This is likely to be caused by air entrapped in the system. If you experience a pulling issue after completing repairs, perform the following procedure to purge the air from one or both of the hydraulic drive systems.

IMPORTANT: WHEN REPLACING THE HYDRAULIC FLUID FILTERS, PRE-FILL BOTH WITH OIL (SAE 20W50 API SL) BEFORE INSTALLING. PRE-FILLING THE FILTERS WITH OIL WILL REDUCE OR POSSIBLY ELIMINATE THE NEED TO PURGE THE SYSTEM OF ENTRAPPED AIR

1.Locate hydraulic reservoir underneath operator’s seat. After thoroughly cleaning the area around the top of the reservoir, remove filler cap. Bring fluid to proper level (1 ½” below the top of the filler neck). With engine off, add SAE 20W50 automotive oil. See Figure 4.6.

2.Open pressure relief valve on hydraulic pump, turning counter clockwise 2 full turns. See Figure

3.Carefully raise the rear of the machine so the wheels are off of the ground. Securely block the machine to prevent it from falling.
