The cut-off machine has externally accessible brush
assemblies that should be periodically checked for wear.

 Unplug the cut-off machine.
 Remove brush cap with a screwdriver. Brush assembly is
spring loaded and will pop out when you remove brush cap.
 Remove brush assembly.
 Check for wear. Replace both brushes when either has less
than 1/4 in. length of carbon remaining. Do not replace
one side without replacing the other.
 Reassemble using new brush assemblies. Make sure
curvature of brush matches curvature of motor and that
brush moves freely in brush tube.

replace.
 Tighten brush cap securely. Do not overtighten.
