Panasonic MCUG522 Operating Guide

This vacuum cleaner has a thermal protector which
automatically trips to protect the vacuum cleaner from
overheating.  

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.

TO CORRECT PROBLEM: 
Turn the vacuum cleaner off and unplug the power cord
from the outlet to allow the vacuum cleaner to cool and
the thermal protector to reset.

Check for and remove clogs, if necessary.  Refer to
CLOG REMOVAL ( page 14).  Also check and replace
any clogged filters and change dust bag, if necessary.

Wait approximately fifty (50) minutes and then plug the
vacuum cleaner in and turn back on to see if the motor
protector has reset.

This vacuum cleaner has a motor protector bypass valve
which prevents motor overheating and damage.

The valve opens to provide cooling air when a clog or
full bag prevents normal air flow to the vacuum cleaner
suction motor. 

You will notice a change of sound as air rushes through
the valve opening.

NOTE: The bypass valve may open when cleaning new
carpet due to reduced airflow caused by the new carpet
lint filling the dust bag quickly. 

Note: Do not block bypass valve.

Edge cleaning feature enables improved cleaning of
carpets near walls and furniture.

The nozzle of your Panasonic vacuum cleaner
automatically adjusts to any carpet pile height.

Feature allows nozzle to float evenly over carpet pile
surfaces.

No manual adjustments required.
