7.2 Hydraulic System

A. Checking Hydraulic Oil Level

The hydraulic oil level should be checked after the first 10 hours of operation. Thereafter, check the oil after every 200 hours of machine operation or monthly, whichever occurs first.

- IMPORTANT -

If the oil level is consistently low, check for leaks and correct immediately.

1.Wipe dirt and contaminants from around the reservoir cap. Remove the cap from the hydraulic oil reservoir.

2.When the machine is "cold" (before operation), visually check the level of the hydraulic system oil. Hydraulic system oil level should be in the middle of the indicator window located on the left side of the machine. See Figure 7-2. DO NOT overfill; (overfilling the oil reservoir may cause oil seepage).

3.Clean the fill cap and install it onto the reservoir.

B. Changing Hydraulic Oil

The hydraulic system oil should be changed after the first 120 hours of machine operation and every 400 hours or annually thereafter, whichever occurs first. The oil should also be changed if the color of the fluid has become black or milky. A black color and/or a rancid odor usually indicates possible overheating of the oil, and a milky color usually indicates water in the hydraulic oil.

- IMPORTANT -

The hydraulic system oil should be changed if you notice the presence of water or a rancid odor to the hydraulic oil.

1.Park the mower on a level surface and stop the engine.

2.Remove the three 1/4" filter guard screws and filter guard from both axles. See Figure 7-3. Clean any loose debris around the perimeter of the filter.

3.Place a suitable container under the hydraulic oil filters. Remove the cover from the left side tank to gain access to the hydraulic expansion reservoir. Remove the fill cap from the reservoir.

4.Remove the hydraulic filters from both axles and allow the fluid to drain into the container. Properly discard the oil when the system has drained completely. See Figure 7-3.

5.Once the hydraulic system has drained, install new hydraulic oil filters to both axles by hand, turn 3/4 to one complete turn after filter gasket contacts the filter base.

6.Reinstall the filter guards and torque the screws to 65 in/lbs.
