11- MOTOR SERVICE
BLOWER MAINTENANCE, CHANGING BRUSHES
This unit is also equipped with an Automatic Motor and Brush Optimization System. To optimize motor life, motor brushes need to be monitored and replaced
PRIOR TO BEING WORN RIGHT OWN TO THE BASE. If brush is worn to the base, there is HIGH RISK of brush damaging the motor. If this happens, you will
require replacement of entire motor.
To avoid this, QUATRO has developed an Automatic Motor and Brush Optimization System. When “Service Motors” light FLASHES continuously, it is time
replace brushes (wear factor is down to 10-20% life remaining). As soon as “Service Motors” light starts flashing continuously order new brushes right away.
When Automatic Motor and Brush Optimization System estimates motor brushes have been worn to dangerous level,
UNIT WILL SHUT DOWN.
BRUSHES MUST BE REPLACED AT THIS POINT, UNIT WILL NOT OPERATE FOR FEAR OF MOTOR DAMAGE.
To optimize and ensure longest brush life, AFTER REPLACEMENT, START motor right away,
speed will automatically default to LOW
.
Operating the motor at Low speed for 15 minutes will “break-in” the new brushes, optimizing and prolong their life.
WARNING: Switch unit off and unplug power cord from wall before servicing the blower.
