6.2 Pumps with Manual Valves

1. Set the adjustable pressure relief valve (6) if required. See section 6.1 for details.

2. With all hydraulic connections made start the pump. Refer to section 5.2

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)
