MOTOR PROTECTION
SYSTEM
Thermal Protector
This vacuum has a thermal protector which
automatically trips to protect the vacuum
from overheating. If a clog prevents the
normal flow of air to the motor, the thermal
protector turns the motor off automatically to
allow the motor to cool in order to prevent
possible damage to the vacuum During this
time the headlight remains ono
To correct problem: If this occurs, turn the
vacuum off and unplug the power cord from
the outlet to allow the vacuum to cool and
the thermal protector to reset° Check for
and remove clogs, if necessary. Also
check and clean/replace any clogged
filters. Wait approximately thirty (30)
minutes and plug the vacuum in and turn
back on to see if the motor protector has
reset.The motor protector will not reset if
the vacuum is not turned off even if the
vacuum has cooled down.
Motor Protector
This vacuum has a motor protector by-
pass valve which automatically opens to
provide cooling air to the motor when a
clog prevents the normal
flow of air to the motor. If
the by-pass valve opens
to prevent motor
overheating and possible
damage to the vacuum,
you will notice a change
of sound as air rushes
through the valve
opening. Motor
Protector
NOTE: Do not block motor protector.
To correct problem: See the TROUBLE-
SHOOTING chart_
NOTE: The motor protector may open
when using attachments or when cleaning
new carpet, due to reduced airflow by the
attachments themselves or by new carpet
fuzz filling the dust bin quickly_ See the
TROUBLESHOOTING section.
PERFORMANCE INDICATOR
SOME MODELS
When the unit is running with normal air
flow, the light on the performance indicator
is off. The light comes on whenever the
airflow becomes blocked. If that occurs,
check the dust bin, clean/replace clogged
filters, and check other possible clog
locations shown in CLOG REMOVAL°
To correct
problem:
See the
TROUBLE-
SHOOTING
chart
NOTE: The
light may
also come on
when using
attachments,
due to
reduced
airflow
through the
attachment.
NOTE: In some cases, the performance
indicator light may not come on if the
motor protector has opened_
