– Connect the female coupler of the hyraulic hose to the corresponding male coupler on
the hydraulic head (see Fig. 5).
3.2) Operation
Move the ON-OFF switch (IG) to "I" position, then:
– Operate push button (GREEN) on the remote hand controller (PC) to activate the motor
and to pump oil to the hydraulic head.
– The pump will stop automatically when the nominal operating pressure is achie ved
and oil pressure will be maintained. If push button is released, the oil will return and the
ram of the hydraulic head connected to the pump, will retract.
NOTE:
– If push button is released before the nominal operating pressure is reached, the pump
will stop and will maintain the oil pressure at the level reached; to complete the operating
cycle, press and hold the push button.
– By pressing the pressure release button (RED), the ram of the hydraulic head connected
to the pump, will retract. To interrupt the "return oil" stage, release the button (the ram
of the hydraulic head will stop in the position reached).
– If required, by pressing the mechanical pressure release button (PS) (see Fig.3) on the
pump, the oil will return to the reservoir indipendent of the status of the external power
supply.
3.3) Alert signalling
The pump is equipped with a self-diagnostic system; the condition of yellow LED (LA) (Fig
3) indicates malfunction with subsequent interruption to pumping.
– STEADY YELLOW LED indicates the intervention of the thermal protection inside the
electric motor, usually due to an intensive and prolonged use of the pump.
Allow the motor to cool and to restore the pump to operation, switch off and on again with
switch (IG).
Note: if the motor is not cooled enough, the pump will not re-start.
– BLINKING YELLOW LED indicates the operating pressure has not been reached within
90 seconds of continuous working.
It is suggested to verify the oil level in the
reservoir, check for oil leakage during
operation and check the connections
between pump and hydraulic head. To
restore the pump to operation, switch
it off and on again with switch (IG) or
press the release button on the hand
controller.
