The Vacuum Indicator Light
If the vacuum indicator light (1) comes on, (see figure
24) or the motor stops, do the following:
1. Put the ON/OFF switch in the "O" position (2).
2. Remove the electrical plug from the electrical
outlet.
3. Check the vacuum hose for an obstruction. If
there is an obstruction in the vacuum hose,
remove the obstruction.
4. Check the brush assembly in the lower housing.
If there is an obstruction in the brush assembly,
remove the obstruction.
5. Check the filter bag. If the filter bag is over 1/2
full, change or empty the bag.
6. Check the filter cartridge. If the filter is dirty,
change the filter.
Thermal Overload
A thermal overload is used to protect the vacuum motor.
If the motor over heats, the thermal overload will stop
the motor. If the motor stops, let the motor cool before
restarting the machine. Check filters. If the motor
continues to stop, consult an authorized service person.
