Changing the Motor Brushes

Motor brushes are a wear item on the engraver and will eventually require replacement. Motor brushes
experience wear during rotary engraving or cutting operations. The life of the motor brushes will
depend on the usage of the machine and they will typically last for several years.
NOTE - Unplug the machine from its power source before attempting this procedure. Failure to
unplug the machine could present an electrical shock hazard.
To easily access the motor brushes for removal, it is recommended to remove the top cover and
carriage cover as described in the previous section.
Use a flat blade screwdriver to loosen the motor brush caps. Inspect the motor brush for length. If the
length is under 1/8th inch (3.2 mm), the motor brush needs to be replaced.
Install the new brush into the motor housing, replace the caps and machine covers.
