Maintenance
and install that vent plug. Torque the plug to 180
7.Continue to add oil through the expansion reservoir until it reaches the FULL COLD line on the expansion reservoir.
8.Install the transaxle guard. Refer to Figure 36 for the correct torque values for the nuts and bolts.
9.Proceed to the Bleeding the Hydraulic System section.
Important: Failure to perform the Bleeding the Hydraulic System procedure after changing hydraulic filters and oil can result in irreparable damage to the transaxle drive system.
Bleeding the Hydraulic System
1.Enter the operator's position. Start engine and move throttle control ahead to 1/2 throttle position. Disengage parking brake.
A.Move the bypass levers into the pushing the machine position; refer to the Pushing the Machine by Hand section in Operation. With the bypass valves open and the engine running, slowly move the motion control levers in both forward and reverse (5 or 6 times).
B.Move the bypass levers into the operating the machine position. With the bypass valve closed and the engine running, slowly move the directional control in both forward and reverse directions (5 to 6 times).
C.Stop the engine and check the oil level in the expansion reservoir. Add the specified oil as until it reaches the FULL COLD line on the expansion reservoir.
2.Repeat step 1 until all the air is completely purged from the system.
When the transaxle operates at normal noise levels and moves smoothly forward and reverse at normal speeds, then the transaxle is considered purged.
3.Check the oil level in the expansion reservoir one last time. Add the specified oil as until it reaches the FULL COLD line on the expansion reservoir if necessary.
Mower Maintenance
Servicing the Cutting Blades
Service Interval: Before each use or daily
Maintain sharp blades throughout the cutting season because sharp blades cut cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease.
Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it immediately with a genuine Exmark replacement blade. For convenient sharpening and replacement, you may want to keep extra blades on hand.
WARNING
A worn or damaged blade can break, and a piece of the blade could be thrown into the operator's or bystander's area, resulting in serious personal injury or death.
•Inspect the blade periodically for wear or damage.
•Replace a worn or damaged blade.
Before Inspecting or Servicing the Blades
Park the machine on a level surface, disengage the blade control switch, and move the motion control levers outward to engage parking brake. Stop the engine, remove the key, and disconnect the spark plug wire(s) from the spark plug(s).
Inspecting the Blades
1.Inspect the cutting edges (Figure 39). If the edges are not sharp or have nicks, remove and sharpen the blades; refer to Sharpening the Blades.
2.Inspect the blades, especially the curved area. If you notice any damage, wear, or a slot forming in this area (item 3 in Figure 39), immediately install a new blade.
