If a previous adjustment has already been made and bristle height does not extend above the baseplate, a new brush assembly should be ordered.
IMPORTANT: Unless the brush is worn as indicated above, both bearings must be in the "NEW" position. When rotating, both
bearings must be in the "OLD" position. Unmatched settings can cause damage to the unit.

Replacing Edge Brush
WARNING: Unplug cord from electrical outlet before servicing.
Turn the power head over. With baseplate facing up, remove the screw located in the center of each edge brush.
Remove both edge brushes and replace with new ones. Replace both screws and tighten.
Replacing the LED Light
The light assembly should be replaced by an Oreck authorized service center whenever it fails to light during operation.
Using an Oreck Fresh Air
Your ORECK U4151 vacuum cleaner has a special ORECK FRESH AIR
bag in the area where the disposable dust bag attaches to the intake tube. Insert tablet in pocket if desired.
Stuffing or Blockage
IMPORTANT: On plush and new carpets, stuffing may occur inside the the intake tube and the lower tube assembly. This is due to excessive
fuzz and loose cuttings in the carpet. Stuffing could occur for the first few cleanings until all the loose material is removed. Due to the high
efficiency of the cleaner, many older carpets will cause stuffing when the cleaner is first used on them. If your vacuum cleaner does not pick
up properly, or makes unusual noise and the outer bag does not fluff up or balloon open, follow these steps:
WARNING: Unplug cord from electrical outlet before servicing.
Check for blockage at the mouth of the intake opening. If there is blockage, remove it with long-nose pliers,
19
a screwdriver or coat hanger. If you can not reach the blockage, remove baseplate. Remove the baseplate by removing 5 screws (see "Adjusting
or Replacing Brushroll").
20
If the blockage is not at the base, remove lower tube. Unhook bag spring, releasing bottom of bag.
21
Twist lower collar counterclockwise to slide up. Pull tube out of base.
22
Check for blockage. If blockage is in the tube, remove with a coat hanger.
23
If tube is not blocked, look into fan housing. Remove debris with long-nose pliers, a screwdriver or coat hanger.
21
To reassemble, check O-ring on tube, and replace if damaged. Replace tube by first lining up slot at base of tube with tab inside fan housing.
Insert tube and push down until the tube is seated. Make sure O-ring is in place against fan housing opening. Replace and tighten collar until
collar locking tabs are locked in place. Reattach bag spring.
Many times blockage occurs due to a full dust bag causing dirt to back down the air flow system. When that happens, the blockage will be at
24
the top of the system, starting in the area where the dust bag connects to the connector assembly.
Note: If the above actions do not correct the problem, contact an Oreck authorized service center or call the customer service center.
