Place the handle in low position. 2. Turn the vacuum cleaner over exposing the underside. Release the lower plate by pressing the two (2) latches that secure it inward, (Fig 1). 3. Separate the lower plate from the vacuum. Installation 1. Close the rear belt cover. 2. Hook the front of the lower plate into the slots on the front of the nozzle housing. Press the lower plate down into place. 3. Fasten the lower plate by pushing the two (2) latches outward. NOTE: For general servicing, it is necessary to eliminate pifiching of any wire during reassembly. After servicing any electrical component or electrical enclosure, the unit should be reassembled and checked for dielectric breakdown or current leakage. Hl AGITATOR ASSEMBLY REMOVAL/INSTALLATION Removal The brushes are not replaceable separately. When the brushes need replacing, the agitator assembly, (without end caps), will have to be replaced. 1. Remove the lower plate as outlined in the LOWER PLATE REMOVAL/ INSTALLATION section. 2. Lift rear belt cover and remove agitator holder. 3. Carefully lift up on the agitator assembly until it clears both sides of the noz- zle housing, (Fig. 2). 4. Remove the belt from the motor shaft by sliding it off between the end of the shaft and the nozzle housing, (Fig. 3). NOTE: The two (2) end caps may come off as you lift the agitator assem- bly out. Look at the exploded view of the agitator assembly in the B Block section for correct assembly of parts. The end caps should be reused. : * Installation 1. Place the belt around the motor shaft, (Fig. 3). + 2, Start the new agitator assembly back into the nozzle housing by placing the side opposite the belt partially into the slot. This will hold the agitator in place, and leave both hands free to place enough tension on the belt to allow that side of the agitator to return to the nozzle housing slot. 3. Place the belt around the agitator pulley on the agitator assembly. Agitator Holder ~~ Lift Agitator Up (Fig. 2) Note: There is a place for the belt to fit on one end of the agitator assembly only. This is the agitator pulley. 4. Use both hands to pull the belt tight, (Fig. 4), and slide the agitator assembly firmly into the slots on each end of the nozzle housing. 5. Rotate the agitator assembly by hand to insure nothing rubs and to check for correct assembly. 6. Replace the agitator holder, and close the rear belt cover. (Fig. 4) |. 7. Replace the lower plate as outlined in the LOWER PLATE REMOVAL/ INSTALLATION section. -12- 2 BELT REPLACEMENT Removal 1.

NOTE: There are two locking tabs present, but only one A POWER CORD/ON-OFF SWITCH REPLACEMENT (Cont.) Installation 1. Insert the new power cord (power cord replacement only) into the dust compartment as far as necessary in order to | place a new cord retainer in proper location on power cord. The proper location is approximately one and one eighth inch- es/thirty millimeters (1 1/87/30 mm) of new power cord outer jacket extending past the cord retainer and washer. The washer goes between the cord retainer and the dust compartment. Attach wires with wire connectors according to the wiring diagram in the front of this manual. ONLY USE A NEW CORD RETAINER, DO NOT REUSE A CORD RETAINER. 2. For switch replacement only, insert the new ON/OFF switch with the numbers 1,2,3, facing toward you, into the dust compartment until secured by the retaining tabs. Use a. wire tie with the part number listed in the C Block parts list and place it in the location shown in Fig. 9 taking care not to overtighten it. Tuck the wire connectors back into the dust com- partment as shown in the close-up view in Fig. 9. 3. Ensure that the Insulator Packing is installed correctly, (see Fig. 10). 4. Replace the switch cover, the two (2) switch cover screws, and the dust cover. Care should be taken not to pinch wires and make sure that the switch cover goes on easily and stays flat. If there is resistance to the switch cover lying flat and in place, stop, remove the cover and make sure that no wires are being pinched. DO NOT USE A POWER SCREWDRIVER TO SECURE THE COVER. NOTE: Any service involving the handle or switch cover area should be followed up with a dielectric or current leakage check of the unit. If you do not have the equipment or are not familiar with the test procedures, take the unit to an authorized servicer. BM HOSE REPLACEMENT ¡Removal 1. Remove the lower plate as instructed in the LOWER PLATE REMOVAL/INSTALLATION section. 2. Pull the hose up out of the nozzle housing. Push the hose out of the back of the nozzle housing. 3. Remove the hose from the suction inlet by unscrewing it. The hose has left hand threads so it must be turned clock- wise to remove. Replacement 1. Replace the new hose by screwing it counterclockwise into the suction inlet. 2. Insert the hose in through the back of the nozzle housing. Push the end of the hose down into the slot in the nozzle. 3. Replace the lower plate as described in the LOWER PLATE REMOVAL/INSTALLATION section. ll MOTOR PROTECTOR REPLACEMENT Removal ”, ea = 1. Remove the dust cover and dust bag. 2. Remove the motor protector (shown in the C Block) by pushing in, one at a time, on the tabs that secure it to the dust compartment. Push the motor protector out the back of the dust compartment. Disassembly 1. Holding a pair of needle nose pliers at an angle and in a position where one side of the pliers is against the locking tab, exert enough pressure on the tab to release needs to be released. For reassembly look at the exploded view in the C Block. Installation 1. Reinstall the motor protector into the dust compartment by aligning the two tabs under the top flange with the slots in the dust compartment and applying pressure until it snaps into place. (Fig. 11) -15- M MOTOR REPLACEMENT ( Removal 1. Remove the dust cover by grasping the top near the On/Off switch and pulling sharply out toward you. Screws 2.

After removing the motor, see MOTOR REPLACEMENT, make Carbon Brushes sure that you have properly identified it. Note specifically that this motor is made in the U.S.A. as identified by the label on the side of the motor, or Made in U.S.A. stamped on the bottom. 2. Remove the amp terminals located on each brush end, (Fig. 13). Replace the brush assembly which should include the brush holder. Reinstall the amp terminals onto the new brush assembly. Complete brush change on one side before starting on the other side. NOTE: Do not drop screws into the motor. - Green Ground Wire (Some Models) t . Made in U.S.A. Screws - (Fig. 19) 3. There are two (2) brushes located on the motor as identified in Fig. 13. A Phillips head screwdriver will be required to remove the ‚ 115-120 тт four (4) screws that hold the brush holders onto the motor. See Fig. 45-47" 13 for screw location. == NOTE: When inserting the brush assembly, be sure that T the TAB on the bottom of the brush holder is positioned in the NE h trough as shown in Fig. 14. 4.
