Adjustments
Drive Control Cable
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. Push the right side of the control out of the
right hole in the upper handle. See Figure 7-5.

2. Pivot control down towards the lower handle.
3. Pivot straight up to remove it from the left
hole in the upper handle. See Figure 7-5.
4. 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 7-6.
Figure 7-6
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.
5. 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.
