6.2 Pumps with Manual Valves
1. Set the adjustable pressure relief valve (8) if required. See section 6.1 for details.
2. With all hydraulic connections and an electrical connection made turn the motor on by pressing the
green 'ON' button (13).
3. Operate the directional control valve (4) to control the cylinder/s or tool/s in use.
For pumps with a 2-way valve: Turning the lever fully clockwise will supply oil to the service port and
advance the cylinder/tool. Turning the lever anti-clockwise will retract the cylinder/tool. (See figure
6.1)
For pumps with a 3-way or 4-way valve: Mid position is the load hold position. Turning the lever so
that it is above the service port (anti-clockwise) will supply oil to the service port and advance the
cylinder/tool. Moving the lever away from the service port (clockwise) will connect the service port
to the tank and retract the cylinder/tool. (See figure 6.2)
