Setup, Performance Testing and
Adjustments
This system has been adjusted at the factory for general operation. Only
the air pressure can be adjusted (explained later in this section).
System operation can be tested using the tools that will be operated by
the system or by using an orifice (Figure 25) to simulate tool use. Use a
1/8 in orifice to test for 30 cfm.
Figure 25 - A700052 Test Tool
1) Install the test tool to the WHASP tank air outlet.
Ensure there are no leaks in the test tool. The system may
not idle down or unload if there are leaks in the lines or
fittings.
Hose reels, etc. should be temporarily disconnected and
the test tool connected directly to the outlet of the
receiver tank. Long and/or undersized air lines will result
in loss of performance.
2) Ensure that the ball valve on the test tool is closed.
3) Start the compressor system and allow the engine to run until it is at
operating temperature.
4) Operate the air compressor system until the oil is warm.
5) Observe the pressure gauge. Pressure should be approximately 150
psi (factory setting).
6) Slowly open the ball valve on the test tool and observe the
operation. The engine should idle up when the pressure drops to
130 psi (20 psi below system pressure).
7) With the ball valve fully open, the pressure should stabilize at
approximately 100 psi (this simulates a tool operating at 30 cfm).
8) Close the ball valve to allow the system pressure to rise.
