Carburetor Adjustment

SERVICE AND ADJUSTMENTS

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.

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:

•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.

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.
