Electrical Projects Little or no vacuum indicates a plugged hose, overfilled bag, loose fan or leaking seal. Check the swivel cap. Noisy operation means defective bearings, loose fan, fan or armature striking, or other loose parts.

To disassemble remove the lid assembly, disposable bag, and inner bag. Withdraw one screw and remove the bag support and the insulator disc. Disconnect the brush leads and bend the tabs on the brush box; remove the brush and spring assembly. Remove the connectors, releasing the cord set and switch leads. Remove the switchmounting nut and push the switch through the mounting hole. Remove the strain relief and cord set. Withdraw the three motor-mounting screws and motor mounts. Lift the motor assembly from the casing. Remove the gasket from the motor assembly. Pry the fan housing from the diffuser. Hold the armature shaft with an Allen wrench and remove the nut by turning it clockwise (left-hand thread). Remove the washer, fan, fan spacer, diffuser, second fan, and bearing. Take out the two nuts, the two motor-mounting bolts, and washers. This releases the baffle, end plate and bearing assembly, top end-plate assembly, bearing spring, cup, and armature. The top bearing can be removed from the armature by withdrawing the screw. The casters may be removed by drilling the rivets. The escutcheon assembly can be removed by pulling the blower plug out and withdrawing the two screws. Disassembly of the attachments, hose, and rug tool can be accomplished by referring to the illustration.
