The motor brushes on the engraving motor should be inspected regularly, and replaced when
worn. Two brush assemblies are included with the accessories package. (One for each side of
the motor.)
Inspect the brushes for possible replacement annually using the following procedure
(see figure 5.3).
The engraving motor is located under the sheet metal top cover. Remove the cover to gain acces
to the engraving motor.
CAUTION: Disconnect the gray table cable from the Phoenix table.
This will ensure that no power is applied to the table.
Locate and remove the 4 button head screws that mount the engraving motor to the carriage.
This will allow the engraving motor to be rotated to gain access to the motor brush caps. You do
not need to remove the motor from the carriage to get to the brush caps. Simply rotate the
motor left or right 1/4 turn to fully see the brush cap. Using a flat tip screwdriver, carefully
remove the motor brush caps and inspect the carbon brush for wear. DO NOT ATTEMPT TO
SEPARATE THE MOTOR BRUSH FROM THE SPRING. Replace brushes as necessary.
To complete the job, reverse the order of the above listed steps and ensure that the motor mount
is secure to the carriage before replacing the carriage top cover.
If either brush needs to be replaced, replace both brushes as a set.
