This operator guide explains routine operation. It is for the operator and for supervisory personnel

attempt to operate it. A separate controller reference manual is available from Milnor for use by
technicians involved in the commissioning, programming, and servicing of the machine.
WARNING: Careless use — can cause death or serious injury and property damage.
�Read the machine manuals before you install, operate, service, or clean
the machine.

areas unless you are a qualified service technician.
This MilTouch™ industrial washer-extractor has one or more physical switches and buttons
(electromechanical controls), as well as a touch-sensitive display screen with virtual controls.
Use the electromechanical controls to apply power, unlock the door, stop the machine immedi-
ately (if necessary), and load and unload the machine. Use the touch-actuated controls on the Mil-
Touch™ display screen to select, run, and monitor formulas.
