Maintenance and Customer Service
• Do not let the unit run while in any one stationary position
for any period of time. Keep the unit moving while in
operation.
• Do not allow to be used as a toy. Close attention is
necessary when used by or near children.
• Use only as described in this manual. Use only
manufacturer’s recommended attachments.
• Do not use with damaged cord or plug. If appliance is not
working as it should, has been dropped, damaged, left
outdoors, or dropped into water, return it to a service
center or call customer service at:
US: 1-800-989-3535 Canada: 1-888-676-7325
• Do not pull or carry by cord, use cord as a handle, close
door on cord, or pull cord around sharp edges or corners.
Keep cord away from heated surfaces.
Your Oreck vacuum cleaner is a product of precise engineering. The
motor bearings are permanently lubricated and should not be oiled. If
you require additional information or have problems with your Oreck
vacuum, you may call ORECK customer service at:
US: 1-800-989-3535 Canada: 1-888-676-7325
Please specify the model number and serial/code number which can be
found on the data plate on the back of the vacuum.
Save your sales or purchase slip. Should your Oreck require warranty
service in the U.S.A., present this slip to the Authorized Service Center
as your proof of purchase date or, in Canada, call customer service.
Polarized Plug Notice
• Do not run appliance over cord.
• Do not unplug by pulling on cord. To unplug, grasp the
plug, not the cord.
• Do not handle plug or appliance with wet hands.
• Do not put any object into openings. Do not use with any
opening blocked; keep free of dust, lint, hair and anything
that may reduce air flow.
This product is equipped with a polarized alternating current line plug (a
plug having one blade wider than the other). This plug will fit into the
power outlet only one way. This is a safety feature. If you are unable to
insert the plug fully into the outlet, try reversing the plug. If the plug
should still fail to fit, contact an electrician to replace the obsolete outlet.
Do not defeat the purpose of the polarized plug.
• Keep hair, loose clothing, fingers and all parts of body
away from openings and moving parts.
Microban® Antimicrobial Protection
• Do not use to pick up anything that is burning or smoking,
such as cigarettes, matches, or hot ashes.
• Do not use without filter bag assembly in place.
• Turn off all controls before unplugging.
• Use extra care when cleaning on stairs.
• Do not use to pick up flammable or combustible liquids,
such as gasoline or lighter fluid, or use in areas where
they may be present.
Oreck added Microban® technology to various touch points, including the
handle, outer bag, top cover, lamp housing and baseplate while
manufacturing this upright vacuum cleaner in order to provide you with
antimicrobial protection that continuously fights the growth of microbes
that can cause stains, odors and product degradation. When microbes,
such as bacteria, mold and mildew come in contact with the product
surface, Microban penetrates the cell wall and disrupts key functions so
they cannot grow or reproduce. Your Oreck will stay cleaner, longer.
• Do not use appliance in an enclosed space where
flammable, explosive or toxic vapors are given off by oil
base paint, paint thinner, some mothproofing substances,
or in an area where flammable dust is present.
• Do not pick up toxic material such as chlorine bleach,
drain cleaner, gasoline, etc. with this appliance.
• Use caution when vacuuming over area rug edges and
fringe.

Parts List
To assist you in identifying components of your vacuum, the parts have
been numbered as follows:

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.

Assembly
To keep your cleaner operating at maximum efficiency, change the dust
bag frequently. DO NOT FILL ABOVE THE LINE INDICATED ON THE
DUST BAG.
fig. 1 Before assembling appliance, remove two screws from the
connector assembly. Remove cardboard insert by pulling
upward.
Be sure the disposable filter dust bag is installed properly.

Insert short screw into top hole and long screw into the bottom
hole then tighten firmly until handle is no longer loose.
fig. 3 Attach cord to cord clip by pressing cord above and below clip
ensuring the cord is fully rested in clip.
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.
Operating Instructions
Make sure disposable paper filter dust bag is in place. DO NOT operate
the cleaner without a paper filter dust bag. Plug the power cord into an
electrical outlet and press the ON(l) - OFF(O) switch on handle
assembly when ready to operate.
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.
Up-Position Lock
fig. 4 Place foot on power head and lean handle back gently to release
lock for vacuum use. Return handle to the full upright position to
engage lock.
Lubrication
NOTE: 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.
The vacuum cleaner motor bearings are factory lubricated and sealed.
Further lubrication is not required.

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.
A little preventative maintenance will
keep your cleaner looking new and
will ensure continued cleaning
effectiveness.
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.
4
CAUTION—Wood Floors, Soft (Vinyl, Asphalt Tile, etc.) Floor
Surfaces and Polished Floor Finishes
fig. 16 Reassemble the belt and the baseplate and check bristle height
above baseplate at each end of brush.
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.
If a previous adjustment has already been made and bristle height does
not extend above 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 will
cause damage to your machine.
Using an Oreck Fresh Air® Tab
Celoc® Hypo-Allergenic Filter System
fig. 20 Your ORECK XL vacuum cleaner has a special ORECK FRESH
AIR® tab pocket. This light-colored pocket is located inside the
vinyl bag in the area where the paper disposable bag attaches
to the intake tube. Insert tablet in pocket if desired.
The Celoc SMMSP outer bag of your vacuum cleaner is a high filtration
medical material designed to filter the smallest of dust particles. For
peak performance, the inside of the outer bag must be cleaned. Turned
inside out, vacuum the inside of the outer bag or hand wash with warm
water, and allow to 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.
Bulb Replacement
WARNING: Unplug cord from electrical
outlet before servicing.
fig. 21 Remove lamp housing by removing two (2) screws in the 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.
To Replace Filter Dust Bag
WARNING: Unplug cord from electrical
outlet before servicing.
BAG REMOVAL:
fig. 6 Unzip outer bag completely.
Stuffing or Blockage
fig. 7 Pull bag cardboard collar to release bag dock door from
IMPORTANT: On plush and new carpets, stuffing may occur inside 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:
connector. Bag dock door will hinge downward.
fig. 8 Gently pull bag cardboard collar upward out of the bag dock.
The dust seal will close automatically.
BAG INSTALLATION:
fig. 9 Slide the cardboard collar completely onto bag dock door.
fig. 10 Firmly push bag dock door with both thumbs on indication point
until it snaps.
WARNING: Unplug cord from electrical
outlet before servicing.
How to Replace a Worn Belt
fig. 22 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. 23).
WARNING: Unplug cord from electrical
outlet before servicing.
fig. 11 Remove the replacement belt from the storage channel.

coat hanger.
fig. 27 If tube is not blocked, look into fan housing. Remove debris
with long-nose pliers, a screwdriver or coat hanger.
fig. 25 To 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. 13 Replace the door by sliding it into the groove at the bottom of
the housing.
fig. 12 Replace the hold down screw and tighten.
To Adjust or Replace Brush
WARNING: Unplug cord from electrical
outlet before servicing.
fig. 28 Make sure collar is not cross threaded on housing. Reattach
bag spring (fig. 24).
fig. 16 To determine if the brush is worn, place a firm straight edge
across the nozzle opening. If brush bristles do not extend
beyond baseplate, brush should be adjusted.
fig. 29 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.
fig. 17 Remove the baseplate by removing 5 screws.
fig. 18 Remove the belt and brush roll from the housing.
NOTE: If the above actions do not correct the problem, contact an
Oreck authorized service center or call the customer service center.
US: 1-800-989-3535 Canada: 1-888-676-7325
fig. 19 Rotate both bearing assemblies at ends of brush roll to show
"OLD" and replace in the holding channels in the housing.
NOTE: The bearing assembly setting marked "OLD" has no ribs on the
top of the assembly. The one marked "NEW" has several ribs. When
rotating bearings, make sure both bearing assembly settings are the
same and face up when replacing the brush roll.
