Range Cylinder for 610, 6610, 6609 and 8609

LO Range - With the control valve lever down, air is supplied from the slave valve to the range cylinder LO range port (1). This air pressure forces the range cylinder piston to the rear (2), engaging the LO range gearing. Air pressure on the piston back, and in the HI range air hose (3), is exhausted out the slave valve.

HI Range - With the control valve lever up, air is supplied from the slave valve to the range cylinder cover HI range port (1). This air pressure forces the range cylinder piston forward (2), engaging the HI range gearing. Air pressure on the piston front side and in the LO range air hose (3), during LO range operation, is exhausted out the slave valve.
