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. Turn off all controls before unplugging.
3. Do not attempt to service vacuum while plugged in.
4. Before handling PC board, discharge static electricity by using anti-static mat and ground strap. If anti-static mat is not available, touch a metal object that is grounded and only handle PC board by outside edges.
WARNING: ELECTRIC SHOCK COULD OCCUR IF USED OUTDOORS OR ON WET SURFACES.
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. The vacuum must be out of the upright position (controlled by the wing rocker switch) unless the nozzle cover is off.
4. The clean air motor must have 12 to 18 volts going to the PC board via the blue/yellow tap wire.
5. The headlights should be on. This assures that the fuses on the PC board are working and there is power in the tap wire. (See
Figure B. PCB Layout and Belt Idler Assembly )
NOTE: All the above conditions must be met on .4 and older models. .5 and newer models must also have the belt installed belt for the hall sensor to work, other wise the direct air motor will come on for 2 to 3 seconds then shut “OFF”.
A.2.
Direct Air Motor is making a squealing sound.
Check for the following conditions:
1. The motor has been changed and the seals are out of place or the motor is not seated properly.
2. The bearings are damaged.
3. Hair or thread is wrapped around the motor shaft and the bearing under fan.
071807 2 I. Common Issues
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. If the airflow is not completely blocked off, the temperature may not reach the point needed to turn on the FBI light.
Additionally, if the bag has been filled with fluffy type material such as carpet fiber, the air flow may not be restricted enough to cause the motor to build up heat.
To test the FBI system:
1. The air flow must be completely blocked off.
2. Place the tool activation dial/rotational valve handle to the tools “ON” position.
3. Blocking off the hose the FBI light should illuminate with in 2 minutes.
B.2.
Bag is full but the FBI did not come “ON”.
Check the bag for content. If the bag is full of carpet fiber or other fluffy material the air flow may not be restricted enough to cause the motor to heat up and the light to illuminate.
B.3.
Bag is not full and the FBI light is on.
The FBI light will illuminate if the pores of the HEPA bag become clogged with a fine powder type substance, such as drywall dust.
This is the most common reason for the light to illuminate.
071807 3 I. Common Issues
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. The nozzle is not sitting on the floor; therefore the airflow is not restricted and will push the cover open.
2. The HEPA filter may be clogged, causing back pressure.
3. The bag inlet seal may be torn allowing air to bypass the HEPA bag, increasing the airflow so the clean air motor cannot relieve all the pressure.
C.2.
The vacuum does NOT run but the lights in the handle switches are on.
The lights in the handle main power switch will come on any time the power cord is plugged into an outlet and the main power switch is turned “ON”. The light in the carpet/floor switch will be on any time there is power to the handle and both the main power switch and the carpet/floor switch are turned “ON.”
1. If the lights are on in the handle switch and vacuum won’t run, check the thermal reset switch.
2. If the vacuum still won’t run, make sure the handle is installed correctly. (See Figure A. Correct Handle Installation )
3. If the vacuum still won’t run see section III. General Troubleshooting, A. Vacuum Has No Power
