HOW TO MAINTAIN

The instructions given in this booklet serve as a guide to routine maintenance. To avoid unnecessary service calls, check the hose, bag and filter often.

Disposable Dust Bags and Filters

The dust bag and motor filter play a very important role in the efficiency of the vacuum cleaner. If the bag or the motor filter become clogged, no air can pass through the cleaner and no cleaning can take place regardless of how powerful the unit is. To keep the cleaner operating at maximum efficiency, change the dust bag frequently and clean the filter as needed.
Some fine particles can restrict airflow very quickly and will decrease performance even before the bag appears to be full. For that reason, when vacuuming carpet fresheners orcleaners, powder, plaster dust or similar fine substances, the bag and filter may need to be changed more often.
