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.

4.While seated in the operator’s position, start the engine. Place engine speed control in FAST position.

5.Release parking brake and move motion control levers out of the neutral lock position.

6.Slowly move motion control levers to the full forward and then to the full reward positions. Repeat this process 6 times.

7.Stop engine and wait for all rotation to stop before leaving the operator’s position.

8.Close pressure relief valve on hydraulic pump, turning clockwise. Tighten snuggly.

9.With pressure relief valve closed, repeat Steps

4thru 7.

10.Remove blocks and lower rear of machine.

11.Check fluid level in reservoir. Add SAE 20W50 automotive oil as required to bring fluid level to 1 ½” from top of filler neck. Do Not over fill.
