IMPORTANT SAFETY INSTRUCTIONS When using or servicing any electrical appliance, basic precautions should always be followed, including the following: WARNING: To reduce the risk of fire, electrical shock, or injury: 1. Do not leave vacuum unattended when plugged in. Unplug from outlet when not in use. 2.
I. Common Issues A. Direct Air Motor A.1. Direct Air Motor will not run. Check the following: 1. The main switch must be “ON” and the floor/carpet switch must be in the carpet position. 2. The tools activation dial/rotational valve handle must be in the tools “OFF” position. 3.
B. Full Bag Indicator (FBI) B.1. Full bag light will not come “ON”. The full bag indicator is controlled by temperature. As the bag fills, the air flow is restricted causing the motor to work harder building up heat in the motor compartment. At a set point, this heat build up causes the FBI to illuminate. It may take up to 2 minutes for the FBI light to illuminate.
C. General Issues: C.1 Why does the dust cover gap open when the lower motor is turned “ON”? The direct air motor pulls more air into the dust compartment than the clean air motor can push out. This could be caused by the following: 1.

A. Disassembly Instructions - Continued A. Step 8. 1. .4 models and older - Remove the direct air motor by lifting up and rotating, and then disconnect the leads. 2. .5 models and newer - Remove screw holding direct air motor in place and lift up. A.
B. Removing the Brush Strips B. Step 1. 1. Remove the base plate by removing the 2 (two) screws. 2. Remove the agitator/brushroll. 3. If the belt un-loops itself from the motor shaft, the nozzle cover may need to be removed by removing the 5 (five) mounting screws on the underside of the nozzle base tray.
C. Replacing the Belt C. Step 1. 1. Remove the base plate by removing the 2 (two) screws. 2. Remove the agitator/brushroll. 3. Remove the 5 (five) mounting screws on the underside of the nozzle base tray. (See Figure C. Location of Nozzle Cover Screws) C.
D. Replacing the LED Light Board D. Step 1. Remove the 5 (five) mounting screws on the underside of the nozzle base tray. (See Figure C. Location of Nozzle Cover Screws) D. Step 2. Remove the 3 (three) screws holding the light board onto the nozzle base tray - the middle screw may have the ground wire attached.
F. Replacing the Main PC Board Note: Static electricity is a potential problem and could damage the PC board if a charge is transferred from yourself to the board during handling and installation. Keep the board in the anti-static packaging until ready to install. It is best to use anti-static protection such as a grounding wrist strap.
G. Replacing the Clean Air Motor G. Step 1. Figure F. Clean Air Motor Wiring 1. Remove the handle and the dust cover. Blue Wire White Wire 2. Place the vacuum face down on the bench. 3. Remove the base plate by removing the 2 (two) screws. 4.
H. Installing the Motor Cover Note the proper location of the two cables passing from the clean air motor compartment to the direct air motor compartment. They should be stored in the channel of the rib wall before the motor cover is reinstalled. If not, the rib wall could pinch and damage the cables.
I. Removing and Replacing the Direct Air Motor Step 1. 1. Remove the handle and the dust cover. 2. Place the vacuum face down on the bench. 3. Remove the base plate by removing the 2 (two) screws. 4. Remove the agitator/brushroll. 5.

I. Removing and Replacing the Direct Air Motor - Continued Step 9. The direct air motor is located in the lower motor compartment (nearest the nozzle). To remove the direct air motor place a hand on each side of motor and lift up and rotate the motor toward the dust compartment.
J. Replacing the Direct Air Motor Fan J. Step 1. 1. Remove the handle and the dust cover. 2. Place the vacuum face down on the bench. 3. Remove the base plate by removing the 2 (two) screws. 4. Remove the agitator/brushroll. 5.

J. Replacing the Direct Air Motor Fan- Continued J. Step 10. 1. Replace the fan. 2. Note the placement of the washer(s) on the fan. The placement of these washers is critical to allow the fan to tighten properly on the motor shaft. 3.
K. Replacing the Rear Wheels NOTE: When replacing the wheels or hubcaps for .4 and older models, the entire wheel/axle set needs to be replaced. K. Step 1. Remove the rear wheel hubcaps by depressing the 3 lock tabs on the inside of the wheel. K.
III. General Troubleshooting A. Vacuum has no power. A. Step 1. 1. If there are lights in the handle switches there is power to the handle, continue to Step 2. 2. If there are no lights in the handle switches, there is no power to the vacuum or the power cord is faulty. a.

A. Vacuum has no power. - Continued A. Step 5. 1. Disassemble the vacuum and disconnect the PC board. 2. Using a test light or meter, test connector 10 (thermal lead) and either 5 or 6 (ground) on the main connector on the wire harness.
B. Direct Air Motor Will Not Run 1. If nozzle cover is installed, the vacuum must be out of the upright position before the direct air motor will run. 2. If the nozzle cover is not installed, the direct air motor should run in the upright position. 3.
B.2. Direct Air Motor Will Not Run: Headlights are on B.2. Step 1. 1. Check the position of tools activation dial/rotational valve handle. Tool dial must be in “OFF” position. Rotate the tool dial fully counter clockwise and then back to full clockwise or “OFF” position. 2.
B. Direct Air Motor Will Not Run - continued B.2. Step 7. If all switches appear to be good: 1. Check the brown wire on the wing rocker switch as follows. Place one lead of the multi-meter on the brown wire from the micro switch.
C. Nozzle Suction Power is Weak 1. Bag may be full or contain fine particles such as drywall dust or talc. 2. Filters may be dirty and need replaced. C.1. There is no suction at the hose C.1. Step 1. The tool activation dial/rotational valve handle should be in the tools “ON”...
D. Excessive Vibration 1. Check the direct air fan for damage. Replace if necessary. (See II. Maintenance Procedures, J. Replacing the Direct Air Motor Fan) 2. The agitator/brushroll may be out of balance. 3. To test the agitator/brushroll for balance: Models .4 and older: 1.
F. Agitator/brushroll Jam Test F. Step 1. 1. Turn the vacuum on. Turn the carpet/floor switch to carpet. Run the vacuum over a sock or towel to jam the agitator/ brushroll. NOTE: Be sure to use thick enough sock or towel material so it doesn’t wrap around the agitator/brushroll. 2.
IV. Trouble Shooting - .4 and Older Models Only A. Full Bag Indicator (FBI) Comes On Too Soon or Not At All If the light comes on too soon, the bag may be full or contain fine particles such as drywall dust or talc. If the light does not come on at all, the bag may be full of fluffy material.
B. Agitator/brushroll Jam Light Comes On Too Soon or Not At All If the sensor is coming on too soon, the customer may be vacuuming one extra plush carpet. Set the height adjustment to higher level and retest. If the sensor still comes on too soon, it may be out of calibration and need adjusting. - See Adjusting the Agitator/brushroll Jam Indicator below.
V. Trouble Shooting - .5 and . Models Only A. Direct Air Motor Starts But Shuts Off in 2 or 3 Seconds NOTE: Any time the nozzle cover is removed the direct air motor will run with the vacuum in the upright position. A.
