5. Operate machine over a test distance while pushing depth control lever (A) forward.

6. Stop machine and check depth at sweeps.

7. When desired depth is measured at sweeps, set depth control so it returns machine to this depth. Note depth indicator position for this depth. Indicator shows relative depth and should not be used for depth setting. Measure sweep depth to set depth control.
