TAB STOP stop (3) on the pressure switch prevents the knob bottom from continuing to turn, remove the knob bottom, re-orient it on the teeth and continue to turn it counterclockwise until it stops.
3. Re-orient the knob tab against the pressure SWITCH TAB STOP .
4. Replace the front cover and secure with the three screws.
5. Replace the pressure control knob into the knob bottom but do not secure with the screw. Turn the knob fully clockwise to maximum.
6. Connect the pressure gauge to the outlet fitting.
7. Connect a high-pressure hose and gun to the pressure gauge.

Me parece que as palavras TAB and STOP estão trocadas. Não seria
pressure switch STOP TAB?
Realinhe a guia do botão com a guia de parada do botão de pressão?
