Thermal cut-off

This vacuum cleaner has a special thermostat that protects the vacuum in case of motor overheating. If the vacuum suddenly shuts off, push the power switch to off (O) and unplug the vacuum. Check the vacuum for a possible source of overheating such as a full dust cup, blocked hose or clogged filter. If these conditions are found, fix them and wait at least 30 minutes before attempting to use the vacuum. After the 30 minute period, plug the vacuum back in and turn on the switch. If the vacuum still does not work, take it to a Eureka authorized service center for repair or call 1-800-282-2886.
