WARNING!!!
This press is exclusively prepared to be used only by one operator.
To prime, jog the start button (electric motor). When the unit emits a dull sound with no jumps
and the sound of the pump is constant. An uneven “tinny” noise indicates there is air in the
pump.
The oil in the reservoir may fall on start up due to:
1. absorption of volume by the cylinder
2. Absorption of volume by the pumping unit.
3. Discharge of air bubbles remaining in the piping.
It is necessary to top off the level of oil bringing it up to the correct height, by checking the level
gauge. The level should be about half way up the stick.
Operation
Before starting any operations make sure there are no other persons in the immediate vicinity of
the machine.
It is strictly forbidden to pass under the work table.
To operate the cylinder, activate the master switch, and then operate the distributor lever Fig. 8.
Pulling - the lever toward the operator (Pos. 2) the piston rod lowers.
Pushing - the lever from the opposite side to the operator (Pos. 3) the piston rod will go up.
Releasing - the lever will return to the neutral position stopping the ram from moving (Pos. 1).
With the hand wheel positioned on the side of the distributors (Fig. 8 Pos. 4) it is possible to
adjust the operating pressure continually and therefore the pressing force of the cylinder. The
pressure gauge (Fig. 7 Pos. 5) allows displaying the pressure during the working phases.
Adjustment of the maximum pressure must be made starting from the lower value and gradually
increasing to reach the pressure necessary to perform the operation to be carried out.
Dake declines all liability for damage to things and/or persons caused by tampering with
the pressure control valve fitted on the unit.
