Genuine Toshiba owner's manual. Couldn't really ask for more. And written in understandable English in contrast to a few recent experiences I have had with manuals for other equipment other than Toshiba but made in China and written in "Chinglish"!

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. Clear a clogged hose with the blower, change the bag if it is full, and clean the motor filter when it is dirty.
Disposable Dust Bags and Filters
The dust bag and motor filter play a very important roll in the efficiency of the vacuum cleaner. The purpose of the dust bag is to trap dirt, but at the same time, the paper bag must be porous enough to allow air to pass through. 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 or cleaners, powder, plaster dust, or similar fine substances, the bag and filter may need to be changed more often. Use GENUINE ELECTROLUX spares and accessories. Look for the Genuine Electrolux product symbol. Call Electrolux on 08706 055055 for assistance.
How to Remove Disposable Dust Bags
NOTE: Turn off vacuum and unplug the electrical cord before changing dust bag or cleaning motor filter. Never operate the vacuum cleaner without the dust bag or filter.
