SECTION 3-OPERATION Raising/Lowering the Hydraulic Lift NOTE: For this procedure, refer to FIGURE 3.2. Raising the Lift NOTE: Ensure the control valve is in the closed position (control valve positioned towards pump handle). 1. Move the pump handle up and down to raise the lift. Lowering the Lift NOTE: Ensure the control valve is in the open position (control valve positioned away from pump handle). NOTE: The weight of the person on the lifting arm causes the lift arm to lower when the control valve is open. NOTE: The rate of descent is controlled by varying the amount that the control valve is opened. A safety gate is part of the hydraulic system that maintains a SLOW constant descent of the boom regardless of how far the control valve is opened.
