The Throttle Control is adjusted at the factory to provide good results
without adjustment in most typical, compressor applications. Some
applications may require adjustments to provide the necessary
airflow and pressure.
Engine RPM adjustments must be made so that the amount of air
delivered by the system matches the requirements of the tools or
equipment that you will be using.
Airflow and system pressure are related. If airflow demands on the
system are low, operating pressure will remain high. If airflow
demands are high, operating pressure will reduce. By making
adjustments to the engine speed while operating a specific tool, you
will achieve optimum performance.
If you must set up a system without knowing the demands on the
system, you can make engine speed adjustments by using an orifice
in the outlet to simulate tool use. The diagram below shows a
system testing and adjustment tool, (VMAC part # A700052) that you
can use to simulate different operating situations. Install this tester
to the tank output fitting before making any changes.
Use the correct orifice for the VR70 or VR150 system.
These orifices are different and must be used for the
correct application.
For 70 CFM application, (VR 70) use a .190 ORIFICE,
(part #3200224).
For 150CFM application, (VR150) use a .250 ORIFICE,
(part #3200223).
