Adjusting the Motion-Control Linkage 11. Adjust the pump-control-rod lengths by rotating the nut in the appropriate direction until the wheels slightly creep in reverse (Figure 104). Located on either side of the machine, below the seat, are the pump-control linkages. Rotating the end nut with a 1/2-inch deep socket wrench allows fine tuning adjustments so that the machine does not move in neutral. Any adjustments should be made for neutral positioning only.
Hydraulic System Maintenance Hydraulic System Safety • Seek immediate medical attention if fluid is injected into skin. Injected fluid must be surgically removed within a few hours by a doctor. • Ensure that all hydraulic-fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to the hydraulic system. • Keep your body and hands away from pinhole leaks or nozzles that eject high-pressure hydraulic fluid.
2. Shut off the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 3. Allow the engine to cool. 4. Locate the filter and guards on each transaxle-drive system (Figure 106). 5. Remove the 3 screws securing the filter guard and guard (Figure 106). 4. Install the filter guards over each filter that you previously removed. 5. Use the 3 screws to secure the filter guards. 6. Verify that the vent plugs are removed before adding the fluid. 7.
2. 3. Start the engine, move the throttle control ahead to the 1/2 throttle position, and disengage the parking brake. A. Move the bypass levers into the pushing the machine position. 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.
