□
Operate the system with an air tool for at least 1/2 hour (1 hour
preferred).

Watch the underhood operation to make sure that belts rotate
properly, pulleys rotate smoothly and nothing is rubbing or
contacting hot parts.
□
Check all components, connections and fasteners once the
engine is turned off and the system has cooled.
□
Check the coolant level after the engine has been operated.
□
Check the compressor oil level after the engine has been shut
down and the oil level has had time to stabilize.
5.3 Setup, Performance Testing and Adjustments
This system has been adjusted at the factory for general operation. If
your operation requires different settings, refer to the owner’s manual
for specific instructions on how to adjust the system.
You can test the system operation using the tools that will be
operated by the system or you can test operations using an orifice in
the outlet to simulate tool use (Figure 5.1).
Figure 5.1
1. Install the test tool in the tank outlet fitting. If you are using the
VMAC test tool, use the correct orifice fitting (small hole for
VR70, large hole for VR140).
