ENGLISH
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 metal strip on the base of the cleaner could be damaged
if used on concrete or abrasive surfaces, and, therefore, cause damage
to wood floors, soft (vinyl, asphalt tile, etc.) floor surfaces and polished
floor finishes. 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.
Celoc
®
Hypo-Allergenic Filter System
The Celoc SMMS 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. 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.

"NEW" has several ridges.
When rotating bearings, make sure both bearing assembly settings are
the same and face up when replacing the brush roll.
fig. 17 Reassemble the belt and the baseplate and check bristle height
above baseplate at each end of brush.
If a previous adjustment has already been made and bristle height does
not extend above baseplate, a new brush assembly should be ordered.

bearings must be in the “NEW” position. When rotating, both
bearings must be in the “OLD” position. Unmatched settings will
cause damage to your machine.
Using An Oreck Fresh Air
®
Tab
fig. 21 Your ORECK XL vacuum cleaner has a special ORECK FRESH
AIR
®
tab pocket. This pocket is located inside the outer bag in
the area where the disposable paper bag attaches to the intake
tube. Insert tablet in pocket if desired.
Bulb Replacement
WARNING: Unplug cord from electrical
outlet before servicing.
fig. 22 Remove lamp housing by removing two (2) screws in the top of
the lamp housing. Pull burned out bulb from holder and replace
with new bulb. Use only Oreck replacement parts. Replace
lamp housing by replacing two screws in the top of the lamp
housing.
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.
fig. 23 Check 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 cannot reach the blockage, remove
baseplate
(fig. 24).
fig. 25 If the blockage is not at the base, remove lower tube. Unhook
retainer spring, releasing bottom of bag.
fig. 26 Twist lower collar counterclockwise to slide up. Pull tube out of
base.
fig. 27 Check for blockage. If blockage is in the tube, remove with a
coat hanger
.
fig. 28 If tube is not blocked, look into fan housing. Remove debris
with long-nose pliers, a screwdriver or coat hanger.
fig. 26 T
o reassemble, check O-ring on tube, and replace if damaged.
Vacuum will not operate properly without the tube O-ring. Slide
O-ring to approximately 2" from base of tube. Replace tube by
first lining up slot at base of tube with inner tab inside fan
housing. Then reinsert 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.
fig. 29 Make sure collar is not cross threaded on housing.
Reattach
bag spring (fig. 25).
fig. 30 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 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.
