There are three LED’s located on upper portion of the Presto Control. A
red LED

yellow
LED
in the center.
The RED LED’s display the following:
On continuously
= The Presto is detached.
Slow Flash
= The Presto is in the Manual Milking Mode
Three Quick Flashes
= This occurs only when the prep timer is activated. 10 seconds before zero the red
light flash providing a visual indicator it is almost time to attach the milking unit onto the cow.
Slow Flash
= While in the wash mode if the Presto is in wash disable. (See wash mode instruction).
The YELLOW LED displays the following:
The YELLOW (Caution) LED turns on for three separate reasons, high conductivity, high temperature or
premature (low flow detach) in all cases the corresponding line on the Presto display flashes simultaneously.
For example if the yellow light is on and the milk temperature is flashing at the same time,
this indicates the milk temperature is high.
Installation Test
The following steps are to be preformed by the dealer prior to the first milking.
This will test the general operation of all valves, cylinders, and controls.
1. Turn power supply on and enable the air supply and/or vacuum supply to the detachers.
2. Verify in the attached mode that the detacher extends the rope or chain and the shutoff valve allows
vacuum to the claw.
3. Verify in the detached mode that the detacher retracts the rope or chain and the shutoff valve is closed
and there is no vacuum to the claw.
4. Verify that a minimum of 6 inches, of milk hose rise is present prior to the flow-cell.
5. Verify that all screws were tightened on enclosures to prevent moisture leaks.
6. Consult with the Dairy owner to be sure that the units are set up to give the desired take off performance.
7.
Be sure that all controls are set-up the same.
How To Milk
1. Press the right ATTACH/DETACH switch. The detacher will release the claw and open the vac-
uum to the claw. The NO Milk LEDs will be flashing to indicate the absence of milk flow.
2. Pull out enough rope or chain so that the claw can be attached to the cow.
3. Attach the claw to the cow’s teats.
4. To milk in Manual Mode use the left switch an indication will occur.
5. To continue milking after a kick off or premature takeoff select Manual then Attach when milking
resumes deselect manual for automatic take off.
