4.1.
FITTING THE FEET
4.1.1.
Attach the permanent press feet (figs.1 & 2).
4.1.2.
It is recommended that, for safest operation, the press is secured to the floor using
the fixing holes in the feet.
fig.3
4.2.
FITTING THE PUMP HANDLES
4.2.1.
The press is supplied with the pump handles disconnected, to save damage in
transit (fig.3).
4.2.2.
Cut the plastic ties to release the pump handles (fig.4).
4.2.3.
Fix pump handle by means of screw, guide bush and nut (fig.5).
4.2.4.
Fit the long pump handle into the socket of high speed pump (fig.6).
5. OPERATION
5.1.
BLEEDING THE HYDRAULIC CIRCUIT
5.1.1. Before first use, any air trapped in the hydraulic circuit will need to be bled.
5.1.2. To do this: open the release valve and pump both pumps 10 times.
5.1.3. Close the release valve and pump a further 10 times. The ram should
extend.
5.1.4. Open the release valve again; the ram should retract.
5.1.5. If the hydraulic circuit still appears sluggish, repeat the process.
5.2.
USING THE PRESS
5.2.1. Insert the saddle into the ram head and secure with the grub screw (fig.7).
5.2.2. Lift or lower the table to the required height and insert the pins to support it.
5.2.3. Place the arbor plate on the press bed frame, then place workpiece onto the
arbor plate and align beneath the ram as required.
NOTE: care must be taken to ensure an arbor does not fall from the press
work table. If necessary, fix in position.
5.2.4. Close the release valve by turning it clockwise fully.
5.2.5. Pump with the high speed pump until the saddle is close to the workpiece.
5.2.6. Use the low speed pump to perform the pressing operation, monitoring the
pressure via the pressure gauge. Using this pump allows greater control and
feel.
5.2.7. When the operation is finished, release the pressure gradually by opening
the release valve slowly.
5.2.8. When the ram has retracted fully, remove the work from the table.
5.2.9. When the press is not in use, ensure that the ram is retracted fully to help
avoid corrosion.
