Operating Recommendations

This new ORECK XL High-Speed Upright is one of the finest, fastest, and strongest units in its class. You’ll love the way it cleans, gets under things, and it’s SO lightweight and easy to use.

The following are a few simple suggestions regarding its operation:

1.When inserting a new disposable paper filter dust bag—FIRST PUFF OUT and OPEN THE BAG.

2.When the disposable filter dust bag is full, REPLACE IT.

3.If at any time the machine does not pick up properly or makes an unusual noise, STOP OPERATION and service.

4.Although your upright will pick up pins, paper clips, and other small objects, it is recommended that these be removed from the floor before you vacuum. Failure to do so may result in permanent damage to the motor suction fan and its housing.

5.WARNING: Do not use your vacuum cleaner on damp or wet surfaces. This will cause damage to the vacuum cleaner and is dangerous to the user. Damage caused by use on wet or damp surfaces is not covered under warranty.

6.REPLACE THE BELT EVERY 6 MONTHS.

7.Change the disposable filter dust bag at least once a month— even if it is not full! The collected dust in the dust bag can cause odor, attract moisture, and can affect the efficiency of the cleaner.

8.DO NOT run the vacuum cleaner over the cord. The revolving brush could damage the cord.

9.Use caution when vacuuming over area rug edges and fringe.

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 Filter Dust Bags

Disposable paper dust bags play a very important role in the efficiency of your ORECK vacuum cleaner. The purpose of the filter bag is to trap dirt, but at the same time it must be porous enough to allow air to pass through. If the filter 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.

All 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.

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.

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.

General Cleaner Care

At least once a month, check for and remove excessive lint, string or hair from revolving brush.

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.
