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.

24Check for blockage at the mouth of the intake opening. If there is blockage, remove it with long-nose pliers, 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”).

25If the blockage is not at the base, remove lower tube. Unhook bag spring, releasing bottom of bag.

26Twist lower collar counterclockwise to slide up. Pull tube out of base.

27Check for blockage. If blockage is in the tube, remove with a coat hanger.

28If tube is not blocked, look into fan housing. Remove debris with long-nose pliers, a screwdriver or coat hanger.

26To 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.

29Many 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 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
