models will require the higher end of this range while
smaller models will want to be within the lower end.

On older models without an electronic down pressure
valve, less PSI is required and pressure should fall
within the 1000 - 1500 PSI range.
8.
Release the lock disc

Adjust the knob
for an initial value of 800 psi on
the gauge
