Adjust the drive control cable if the yard vacuum does not self propel with the drive control engaged, or if the unit hesitates while the engine maintains the same speed after approximately 20 hours of use.

To move the z-fitting of the drive control cable from its factory set position in the front hole of the drive control to the rear hole, proceed as follows:

1.a. Push the right side of the control out of the right hole in the upper handle. See Figure 5-1A.

b.Pivot control down towards the lower handle.

c.Pivot straight up to remove it from the left hole in the upper handle. See Figure 5-1A.

2.There is now sufficient slack in the drive control cable to grasp the z-fitting with your hand and move it from the front hole to the rear hole of the drive control. See Figure 5-1B.
