Machine does not start
Control Settings
Make sure machine is plugged into the wall.
Verify the on-off switch is in the ON position
and the pressure control knob is turned all the
way to the right (clockwise for maximum pres-
sure).
Pressure Control Assembly
(Board)
If the power indicating light is still out after
checking the control settings and power
source, replace the pressure control assem-
bly.
Motor
Remove the motor brush covers and turn the
machine ON. Set the pressure control at max-
imum pressure and check for DC voltage
across both brush terminals. It should read
greater than 80 volts DC.
If you have DC voltage, turn the machine off
and unplug it from the wall. Check to make
sure the brushes are making good contact
with the armature. Replace the brushes if they
are less than 1/2” long. If the brushes are
good, replace the motor.
