MOTOR PROTECTION SYSTEM
BY-PASS VALVE
Thermal Protector - Suction Motor
This vacuum cleaner has a thermal
protector which automatically trips to
protect the vacuum cleaner suction motor.
If a clog prevents the normal flow of air
to the motor, the thermal protector turns
the motor off automatically. This allows
the motor to cool in order to prevent
possible damage to the vacuum cleaner.
Thermal Protector - Brushroll Motors
This vacuum cleaner has thermal
protectors which automatically trip to
protect the brushroll motors. The thermal
protectors turn the motors off
automatically. This allows the motors to
cool in order to prevent possible damage
to the vacuum cleaner.
To reset thermal protectors: Turn the
vacuum cleaner off and unplug the power
cord from the outlet to allow the vacuum
cleaner to cool and the thermal
protectors to reset.
PERFORMANCE/SAFETY FEATURES
CAUTION
Always return the vacuum cleaner to the
upright position before using the hose
and attachments. Failure to do so may
result in overheating of the brushroll
motors and can cause the thermal
protectors to trip.
Check for and remove clogs, and replace
bag if necessary. See REMOVING CLOGS
Section (pages 19-20). Also check and
replace any clogged filters. Wait
approximately 50 minutes before restarting
vacuum cleaner.
This vacuum cleaner has a By-Pass Valve
which prevents motor overheating and
damage. The valve opens to provide
cooling air when a clog prevents normal
air flow to the vacuum cleaner suction
motor. You will notice a change of sound
as air rushes through the valve opening.
To correct problem, install a new dust
bag. If using attachments, adjust suction
control to allow for greater air flow.
NOTE: The By-Pass Valve may open when
using attachments or when cleaning new
carpet due to reduced airflow caused by
the attachments themselves or by new
carpet lint filling the dust bag quickly.
NOTE: Do not block By-Pass Valve.
