Drive Control Cable Adjustment

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 15A.

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 15A.

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 15B.

IMPORTANT: Make sure to insert the z-fitting into the rear hole as it was inserted in the front hole, that is from the outside of the drive control.

3.You may now carefully reinstall the drive control by performing the previous steps in the opposite order and manner of removal.

IMPORTANT: Once assembled and prior to restarting, make sure that the cable is properly adjusted. With the drive control disengaged, the unit should freely pull in reverse.

Removing The Flail Screen

If the discharge area becomes clogged, remove the flail screen and clean area as follows.

1.Stop the engine. Make certain the chipper/shredder vacuum has come to a complete stop.

2.Before unclogging the discharge chute, disconnect and ground the spark plug wire to retaining post.

3.Remove the vacuum bag or blower chute from the unit as instructed in the OPERATION section to obtain access to flail screen.

4.Remove the three self tapping screws securing the belt cover, and remove the belt cover. See Figure 16.

5.Remove self tapping screw on right side of unit that attaches to the flail screen. See Figure 17.

6.Remove hex screw on top of rear housing near mounting bracket and the flange lock nut that secures flail screen. See Figure 17.
