Operating Instructions

This new ORECK 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 dust bag -FIRST PUFF OUT and OPEN THE BAG.

2. When the disposable 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. For optimal performance, replace the belt every 6 months. 

7. Check the disposable filter dust bag at least once a month.

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.

Before assembling appliance, remove two screws from the connector assembly. Remove cardboard insert by
pulling upward.

Slide upper handle section over the matching section of the connector assembly. Hold tab of cord strain relief 
flush with 

TOP 

hole in connector assembly. Insert screw through hole in tab of cord strain relief and firmly 

tighten to connector assembly. Insert remaining screw in bottom hole of connector assembly and tighten firmly.

Snap cord assembly into the cord clip located on the left side of the collar. Leave excess cord at the power head
to allow movement.
