2. Disconnect the Outlet Hose from the Outlet Duct by loosening the
Thumbscrew Clamp and pulling the Hose from the Outlet Duct.

it clockwise.
4. Install the new Hose by screwing the Hose counterclockwise into the

attach it to the Outlet Duct without resting on the corner of the Collector.

Outlet Duct and turn the Thumb Screw Clamp until tight.
6. Slide the Lanyard up onto the Cuff to hold it in place.
Before performing any maintenance, repairs or inspection, you must first shut
off the mower and leaf and lawn vacuum engines, wait five minutes for all
parts to stop and cool, and disconnect the spark plug wire of the leaf and lawn
vacuum.
