stop completely or slow down. See instructions in the manual for replacing belt.
Extra belts are stored in the plenum cover 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.
Lubrication
The vacuum cleaner motor bearings are factory lubricated and sealed. Further lubrication is not required.
General Vacuum Cleaner Care
At least once a month, check for and remove excessive lint, string or hair from revolving brush.
Wipe the outside of the vacuum cleaner with a damp cloth. Also clean the plenum, base of cleaner and housing area. If there is dust in the outer bag, vacuum it.
A little preventative maintenance will keep your cleaner looking new and will ensure continued cleaning effectiveness.
Use floor and floor finish manufacturer’s recommended methods of cleaning. The metal strip on the base of the vacuum 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.
DS1700HY: Hepa / Celoc®
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. For best results, the Celoc SMMS outer bag should be replaced once a year. 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. By changing the bag often, you increase the cleaning power of your vacuum cleaner.

How to Replace a Worn Belt
WARNING: Unplug cord from electrical outlet before servicing.
fig. 15 Remove plenum cover.
fig. 20 Remove a replacement belt from the plenum belt storage area.
fig. 21 Remove belt door by using a screwdriver and removing the cover screw.
fig. 22 Remove belt from brush roll pulley and the motor drive shaft.
fig. 23 Loop the new belt over the motor drive shaft. Place the opposite end of belt on top of brush pulley and roll the belt around the pulley using your thumb and finger. Ensure belt is completely around the pulley.
fig. 24 Replace the belt door. Insert and tighten cover screw.
To Adjust or Replace Brush
WARNING: Unplug cord from electrical outlet before servicing.
fig. 25 To determine if the brush is worn, place a firm straight edge across the nozzle opening. If brush bristles do not extend beyond base plate, brush should be adjusted.
fig. 26 Remove 4 screws from top cover.
fig. 27 Remove 4 screws from brush roll cover.
fig. 28 Rotate both bearing assemblies at ends of brush roll to show “OLD” and replace in the holding channels in the housing.
fig. 29 NOTE: The bearing assembly setting marked “OLD” has two bars (ll) on the top of the assembly. The one marked “NEW” has one bar (l). When rotating bearings, make sure both bearing assembly settings are the same and face up when replacing the brush roll.
Reassemble the belt, inner cover and top cover and check bristle height above base plate at each end of brush. See: fig. 25.
If a previous adjustment has already been made and bristle height does not extend above base plate, 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.
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 can occur for the first few cleanings until all the loose material is removed. Due to the high efficiency of the vacuum cleaner, many older carpets will cause stuffing. 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. 30 Check for blockage at the mouth of the intake opening. If there is blockage, remove it with
fig. 31 If tubes are blocked, remove plenum cover and run a coat hanger through tubes to clear blockage.
fig. 32 If blockage can not be removed at plenum, twist lower collars counter clockwise to slide up. Pull tubes out of pivots. Check for blockage inside pivots. If blockage is in the pivots, remove debris with
fig. 33 Many times blockage occurs due to a full dust bag causing dirt to back down the air flow system. If that happens, the blockage will be at the top of the system, starting in the area where the dust bag connects to the plenum. Check openings inside plenum for blockage.
fig. 34 To reassemble, Replace plenum. Check seals on tubes, and replace if damaged. Vacuum will not operate properly without the tube seals. Reinsert tubes into pivots and push down until the tubes and seals are seated properly. Replace and tighten collars securely.
NOTE: If the above actions do not correct the problem, contact an Oreck authorized service center or call the commercial customer service center. USA & Canada
