General

Information

.

The performance of your new cleaner greatly depends upon care and maintenance. The instructions in this manual
will guide you in performing basic care and maintenance. To obtain the most satisfying years of service read the
instructions and keep them handy for future reference.

Disposable Odor Fighting Dust Bags

Disposable Odor Fighting dust bags play a very important role in the efficiency of your ORECK vacuum cleaner.
The purpose of the dust bag is to trap dirt, but at the same time it must be porous enough to allow air to pass
through. If the dust bag becomes clogged, no air can pass through the cleaner and cleaning cannot take place,
regardless of the cleaner’s power. 

To keep your cleaner operating at maximum efficiency, change the dust bag frequently.
DO NOT FILL ABOVE THE LINE INDICATED ON THE DUST BAG.

Be sure the disposable filter dust bag is installed properly. Note: All disposable filter dust bags are not the same.
Your ORECK disposable dust bags have been designed to be used with the ORECK cleaner. Using bags other than
genuine ORECK TYPE CC disposable bags will affect the cleaning ability of your cleaner and could cause damage
to it.

Intellashield

Technology

Oreck added Intellashield technology to various touch points, including the handle, outer bag, and bag dock while
manufacturing this upright vacuum cleaner in order to provide you with antimicrobial protection that continuously
fights the growth of microbes that can cause stains, odors and product degradation.When microbes, such as bacte-
ria, mold and mildew come in contact with the product surface, Intellashield penetrates the cell wall and disrupts
key functions so they cannot grow or reproduce. Your Oreck will stay cleaner, longer.

Celoc

®

Filtration System

The Celoc outer bag of your vacuum cleaner is high filtration medical material designed to filter the smallest
of dust particles. It is important the inside of the outer bag be cleaned. Vacuum the inside of the outer bag or hand
wash, turned inside out, with warm water, and air dry. If desired, the Celoc outer bag can be replaced for renewed
efficiency. The Celoc layered disposable inner dust bag must be replaced once a month even if it is not full. Change
it more often if it is used in extremely dirty areas. Increase the cleaning power of your vacuum by changing the bag
often.

The Belt

The belt on your vacuum cleaner controls the speed of the revolving brush and is very important for the effective 
operation of the cleaner. If the belt becomes stretched or cut, it will cause the revolving brush to stop completely or
slow down. See instructions in the manual for replacing belt.

Note: An extra belt is stored in the baseplate of your cleaner. When buying replacement belts, use ONLY ORECK
genuine belts. Belts other than Oreck belts will not operate the revolving brush correctly and may create undue
stress which will cause damage to the motor and brush bearings. Using belts other than ORECK belts will void the
warranty.

Lubrication

The vacuum cleaner motor bearings are factory lubricated and sealed. Further lubrication is not required.

CAUTION
Wood Floors, Soft (Vinyl, Asphalt Tile, etc.) Floor Surfaces and Polished Floor Finishes

Use floor and floor finish manufacturer’s recommended methods of cleaning. The roller
brush may also scuff very soft finishes. Do not operate the unit while in the upright and locked position. Do not let
the unit run while in any one stationary position for any period of time. Keep the unit moving while in operation.

Note: At least once a month, check for and remove excessive lint, string or hair from
revolving brush. Patented cleaning grooves on brush roll will allow easier cleaning.

Wipe the outside of the cleaner with a damp cloth. Also clean the connector deflector
assembly area, base of cleaner and fan housing area. If there is dust in the outer bag, 
vacuum it or shake it out.

A little preventative maintenance will keep your cleaner looking new and will ensure
continued cleaning effectiveness.
