Measuring the swing speed and the overswing of the machine will determine if there is a need to check the swing motor or the anti-reaction valve. The fine swing control switch (if equipped) must be in the OFF position.Note: The engine speed and/or the machine configuration that is used during this test can affect the results of this test. Refer to Testing and Adjusting, "Engine Performance - Test (Engine Speed)" for the engine speed that was used for this test. Refer to Testing and Adjusting, "Operational Checks" for the machine configurations that were used for this test.Note: The relief valve pressure settings must be set to the relief valve pressure specification before performing this operational check.
