The fine swing control switch is located on the right side control panel.
The fine swing control is installed in order to ensure an exact movement of the swing with minimal shock load. This function is done by equalizing the oil pressure in passage (6) and (11).When fine swing solenoid (5) is de-energized, spool (13) is in the NEUTRAL position. Spool (13) is located in valve (12). The NEUTRAL position creates a closed connection between passages (15) and (9). In this position, the swing circuit operates in the normal manner.When the fine swing control switch is ON, solenoid (5) is energized. Spool (13) shifts downward against the force of spring (16). With the spool in this position, passage (6) is open to passage (11) through passages (15) and (9). Orifices (10) and (14) control the flow rate. Orifices (10) and (14) are located in block (1).Note: When the fine swing control switch is ON, the swing brake is OFF.
