Craftsman 247.770990 Operator's Manual page 15

_, WARNING: Do not at any time make any
adjustment to the unit without first
stopping engine and disconnecting
spark plug wire.
NOZZLE HEIGHT ADJUSTMENT
The nozzle can be adjusted to any of five positions,
ranging from 5/8" to 4-1/8" ground clearance. The
nozzle height has to be adjusted according to yard
conditions. Move the height adjustment levers
forward or backward to adjust the nozzle upwards or
downwards. See Figure 16.
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.

DRIVECONTROL C ABLE 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:
• Remove the drive control by pushing the right
side of the control out of the right hole in the
upper handle. Pivot control down towards the
lower handle and then straight up to remove it
from the left hole in the upper handle. See Figure
17A.
• 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 17B.
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.

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.
CARBURETOR ADJUSTMENT
_ WARNING:
If any adjustments (e.g.
carburetor) are made to the engine
while the engine is running, keep clear
of all moving parts. Be careful of heated
surfaces and muffler.
The carburetor has been pre-set at the factory and
should not require adjustment. If your engine does
not operate properly due to suspected carburetor
problems, take your Yard Vacuum to a Sears Parts &
Repair Center for repair and adjustment.
