6 - OPERATION
THE USE OF THE PUMP IN POTENTIALLY EXPLOSIVE ENVIRONMENTS, IF NOT DULY PROTECTED (PROTEC-
TION NOT SUPPLIED) IS STRICTLY FORBIDDEN. POSSIBLE ACCUMULATION OF ELECTROSTATIC CHARGES.
The pump is extremely simple to use:
●
To activate the pump press gently down with your foot on the end of the treadle marked “
PUMP
” (
fi
g.7, page 3). The pump will start
to deliver pressurized oil and thereby cause the connected machine to operate.
●
When the treadle is released, i.e. when you remove your foot, the pump stops but the pressure is maintained on the oil side so that
the connected machine cylinder holds the load in the position it has reached.
●
To return the pressure to zero and hence retract the machine cylinder to its starting position, press the treadle in the area marked
“
RELEASE
” (
fi
g.8, page 3).
WARNING
IMMEDIATELY AFTER THE PUMP INSTALLATION, THE CIRCUIT MAY CONTAIN AIR LOCKS WHICH PRE-
VENT PRESSURIZATION. IF THE PUMP IS UNABLE TO PRESSURIZE THE OIL CIRCUIT, PROCEED AS
DESCRIBED BELOW.
THE OPERATIONS DESCRIBED BELOW MAY BE PERFORMED ON THE PEDAL USING THE HANDS, SOLELY
IF YOU PRESS ONLY "PUMP" AND "RELEASE" ZONES, INDICATED ON THE PEDAL ITSELF
●
Lift the treadle at the “
PUMP
” side. There is a
fl
at pushbutton beneath the treadle.
●
Use one hand to press the “
RELEASE
” side of the treadle while pressing the pushbutton under the “
PUMP
” side with your other hand
(
fi
g.9, page 3). Maintain the pressure on the “
RELEASE
” side and the “
PUMP
” pushbutton for about 15 seconds.
The pump should now work correctly. If you still have problems, repeat the above mentioned procedure.
