HFA - High Flow Supply line - Circuit supply line is sized to run industry standard attachments corresponding to weight of carrier without excess line velocity.
HP - High Pressure Return and Supply lines 5000 PSI - Circuit includes high pressure hoses on both sides.
XHFB - Extra High Flow Return Line - Circuit return line is larger than standard to allow for lower velocity through piping, creating less backpressure and more efficient operation, commonly required for single direction breakers, compactors and other attachments.
BV - Ball Valve Terminated Lines - Ball valves with manual on/off levers which block the oil flow in the auxiliary lines to aid in attachment removal.
TL - Thumb cylinder lockout valves - Allow for hydraulic "lock-out" of the thumb cylinder when other attachments are connected.
CSV - Manual ball valve for 1 or 2-way attachments - manual oil direction valve allowing oil direction change for dual or single direction attachments such as thumb cylinders or hammers/compactors.
EFS - Automatic ball valve actuation for 1 or 2-way attachments - Allows operator to change oil direction in an auxiliary circuit from one-way to two-way flow via a cab mounted rocker switch or monitor attachment selection/programming, depending on machine monitor capabilities. EFS works in conjunction with the CSV option, but removes the manual ball valve handle and replaces it with a pilot oil actuator for error-free and simpler operation when switching between single direction and dual direction attachments.
EPC - Monitor integrated auxiliary flow control - Consist of OEM equivalent harness and proportional EPC valve to allow auxiliary circuit flow adjustment via the OEM monitor. A flow meter is still recommended during circuit testing for accurate adjustment.
JCL - Pushbutton Left Hand Joystick - Provides a means of on/off momentary control for single or dual direction auxiliary circuit (hammer/thumb/etc.). Includes left hand joystick with four pushbuttons and a trigger button. This joystick can be used as a "non-active" joystick to match the aesthetics and ergonomics of a right hand active (JC or JPC) joystick.
JPC - Proportional Right Hand Joystick - Proportional right hand joystick allowing variable speed control of the auxiliary circuit via a slider/rocker switch located on the face of the joystick. The joystick also has three pushbuttons to the right of the slider-switch and 2 trigger pushbuttons.
