Remove the bag by sliding the rubber gasket that surrounds the hole in the disposable bag off the plastic inlet stem that protrudes through the side of the canister (figure 2d).

Once the bag is off of the inlet stem, seal the bag by removing the backing from the tab and cover the hole with the flap. Press the flap so that it securely seals over the hole (figure 3d).

This will help prevent dirt and dust from escaping.
Now, lift the bag from the dirt canister and place in a suitable trash container.

Take a new bag and extend it fully (figure 4d),

Slide Bag onto Stem

Carefully replace the lid onto the dirt canister to ensure that it seals properly or it could cause a vacuum leak and reduce the cleaning efficiency of your system.

NOTE: This step is only required in the event that the bag breaks. If bag breakage does occur, it is necessary to lift the plate located under the bag and clean the small screen.

The filter bag should be changed or cleaned when there is 3-6 inches of dirt or anytime there is a noticeable reduction of air flow at the cleaning tool. Initially, the dirt canister should be checked or emptied weekly until some idea can be obtained as to how long it takes to half fill the canister under your normal cleaning routine. All vacuum systems will function more effectively if it is emptied frequently. Under no circumstances should you allow your dirt canister to become more than 3/4 full before emptying. (Note: The canister will fill more rapidly if NEW carpets are being cleaned for there is usually a tremendous quantity of loose fibers that are retained in the carpet from the manufacturing process. In some instances it may take several months before all of these loose fibers are removed.)
