SERVICE AND MAINTENANCE
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:
Push the right side of the control out of the right hole in the upper 1.
handle. See Figure 18A.
Pivot control down towards the lower handle.2.
Pivot straight up to remove it from the left hole in the upper 3.
handle. See Figure 18A.
There is now sufficient slack in the drive control cable to grasp the 4.
z-fitting with your hand and move it from the front hole to the rear
hole of the drive control. See Figure 18B.
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.
