Hi-Force will not always be aware of what equipment this pump will be used to power. It is the responsibility
of the owner and all operators to read, understand and comply with all appropriate safety warnings and
operating instructions relating to the equipment being used.
6.1 Setting the Pressure Relief Valve
NOTE: Setting the relief valve pressure is to be done with hydraulic female couplers fitted to the service
ports only. I.e. No hoses or cylinders/tools fitted.
The procedure for setting the relief valve pressure is as follows:
Turn the pump on by pressing the green 'ON' button (13)
Place the pump in advance mode.
For 2-Way manual valves, turn the level fully clockwise (See figure 6.1).
For 3 & 4-Way manual valves, turn the lever fully anti-clockwise (See figure 6.2).
For solenoid valves, press and hold the 'advance' button on the pendant.
Increasing the Pressure Setting
Release the locking feature and turn the control knob slowly (8) clockwise until the required pressure
is read on the pressure gauge.
Engage the locking feature to lock the relief valve at the desired pressure.
Decreasing the Pressure Setting
Release the locking feature and turn the control knob (8) anti-clockwise until a pressure value lower
than the required pressure is read on the gauge.
Turn the control knob slowly clockwise until the required pressure is read on the gauge.
Engage the locking feature to lock the relief valve at the required pressure.
NOTE: ALWAYS adjust up to the desired pressure and NEVER down. When setting the pump to a lower
pressure, reduce the pressure below the desired value (anti-clockwise) and then increase back up
to the desired pressure (clockwise) as read on the gauge.
NOTE: It's good practice to zero the pressure before storing away. Turn the control knob anti-clockwise
until the pressure gauge reads zero.
