Position (C) allows hydraulic oil to flow in both directions (hydraulic shear and offset boom). Use LOCKED position (A) when the implement does not need to be used.When the pedal is in ONE-WAY FLOW position (B) the pedal can be only depressed forward.When the pedal is in TWO-WAY FLOW position (C) the pedal can be depressed forward and backward.Insert lock pin (1) into LOCKED position (A) when the implement is not being used.
