3. Close the vent knob.
4. Push the pump key and see the pressure (or
vacuum) increase until the necessary pressure is
reached.
Note
The pump motor speed will start slowly when
pressure is low (<15 psi) for better control at low
pressures.
5. Use the fine adjustment vernier to fine tune the
pressure/vacuum indication as necessary.
6. To fully decrease or bleed off the pressure, slowly
turn the vent knob to the open position. When this is
done carefully, the pressure-bleed rate can be
carefully controlled and this helps when taking down-
scale pressure readings.
