OPERATING & MAINTENANCE PROCEDURES
THERMAL-PROTECTION INSTRUCTIONS:
This vacuum cleaner is equipped with a thermal-protec-
tion device, which will interrupt vacuum motor circuit
automatically to prevent the motor from overheating. Air
restrictions for an extended period will result in the
vacuum motor shutting down. If this occurs, press the
switch to turn the vacuum to the OFF position and wait
a minimum of 5 minutes for the motor to cool to a safe
termperature. Be sure to determine the cause of over-
heating and rectifiy the problem before using the vacuum
cleaner again or it will continued to overheat and shut
down. In some instances the vacuum motor circuit is
interrupted because of high motor temperature caused
by a dirty dust bag or an airway blockage. Please un-
plug the vacuum and check the inner paper dust bag
and airway. If the dust bag is too dirty and clogged,
replace it with a new one. If an airway is blocked, please
remove the blockage before reuse. The motor can be
restarted when it is cool.
REPAIR SERVICE
When servicing, use an authorized person only. Use
only identical replacement parts.
