WARNING : Do not at any time make any adjustment
to the unit without first stopping engine and discon-
necting spark plug wire.
NOZZLE HEIGHT ADJUSTMENT
The nozzle can be adjusted to any six positions, ranging from 5/8" to 4
1/8" ground clearance. The nozzle height has to be adjusted according
to yard conditions.
1. Depress nozzle height adjustment lever towards wheel. See Figure
17.
2. Move the height adjustment lever forward or backward to adjust the
nozzle upwards or downwards. Make sure both levers are in the
same position.
3. Release lever towards deck.
NOTE: In general, raise the nozzle height to vacuum a thick layer of
leaves or to operate with the blower chute. Lower the nozzle height for
smoother surfaces.
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 18A.
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 18A.
2. Grasp the 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.
3. 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.
