MAINTENACE – CONTROL
The control requires practically no maintenance once it has been installed. It is a
rugged piece of equipment, but can be damaged if abused.
IF FUSE REPLACEMENT BECOMES NECESSARY, USE ONLY
THE SPECIFIED FUSES. THE USE OF A SUBSTITUE FUSE
MAY CAUSE CONTROL DAMAGES AND VOID THE
CONTROL WARRANTY.
Correct fuses to be used are listed in Table I on page 3 of this manual.

MAINTENACE – MOTOR
Motors supplied by Polyspede are rugged machines specifically designed for
SCR controllers. There are no adjustments to make and maintenance is quite
simple. All moving parts are subject to wear. Brushes are perhaps the only
component requiring periodic maintenance.
Motor brush life is related to motor speed, loading, cycling rate, ambient
temperature, and other variables not controlled by Polyspede. Therefore, only
guidelines can be given for checking this item. Experience has shown that each
application has its own wear rate. Removal of the brushes after each three
months of operation during the first year will give an indication of your specific
wear rate. After three sets of brushes have been used, remove the motor
armature for checking by a competent motor repair shop for possible
commutator refacing.
Armature bearings are sealed and require no additional lubrication.
Replacement should be performed by a reputable service shop, if they become
noisy.
Occasional cleaning of motor vent holes or removal of fan guard to remove dust
accumulation from fans is the only additional maintenance required.
