HYDRAULIC SYSTEM REQUIREMENTS
Refer to the performance charts below to properly match your hydraulic system to the winch performance. The
charts consist of: (1) first layer line pull (LB) vs. working pressure (PSI) and (2) first layer line speed (FPM) vs.
flow (GPM). A motor spool directional control valve is required.
