smoothly. If there is binding while cranking the rollers, the set screws can be used to adjust
the plate. The plate gears and bar all need to be square so there is minimal resistance.
4. Setting the Working Pressure:
In the right and left cabinets where the upper roller comes through, there is a stack of spring
washers used to provide the correct amount of application pressure. Raise the upper roller
so that there is at least a 1/8” gap between the rollers. Bring jam nut #1 (see drawing below)
up so that the stack of spring washers just touch the bracket and back off one full turn. Bring
jam nut #2 up against nut #1 to lock them in place. Inspect the pressure readings. While the
roller is up the 0% or first light should be lit on the pressure read out. If the light is not lit,
locate the main circuit board inside the right cabinet. There is a small potentiometer (small
blue square box with a screw adjustment located on the top) on the board that can be used
to adjust the starting point where the light comes on. Lower the upper roller, the 20% or
second light should come on when the rollers are just contacting. You will start to get flat
rollers at 40%. Continue to crank the hand wheel until full pressure is achieved at 100%
making certain all lights are operating.
Confirm that the height sensor is adjusted properly by comparing the nip opening
with the figure on the digital readout. If adjustment is needed, loosen the mounting
screws on the height sensor and position as required.
