Operations
Adjusting the Table
The press bed height adjusts in relation to the stationary elevation
of the cylinder ram. Do not attempt to manually lift or lower the
press bed. Utilize lift ring and lift chains to incrementally lift or lower
the press bed to the appropriate working height for the material being
pressed. Install the lift ring by removing the press cup at the ram end.
Install the lift ring on the ram, lift beyond the 3/8” bore through the
ram and secure with 3/8” grade 8 linchpin through ram. Identify the
horizontal keyholes at both ends of the press bed assembly.
To raise the table, extend the ram and lift ring completely. Link the
chains provided over the lift ring and drape chains through the key-
holes in the press bed assembly. Make sure the chain links are equally
distributed either side of the ram to the press bed keyholes. Engage
chain into keyholes. Once secure, carefully raise the ram so that any
slack is drawn out of the chains. Once tension is put on the chains,
carefully remove the lynch pins and hardened pins securing the press
bed to the rail assembly. With the pins removed, carefully retract the
cylinder to raise the press bed to the desired position. Insert hardened
pins, re-install linchpins and remove lift chains and lift ring hardware to
complete the press bed change.
To lower the table, retract the ram and lift ring to within ½” of complete
retraction. Link the chains provided over the lift hooks and drape
chains through the keyholes in the press bed assembly. Make sure the
chain links are equally distributed either side of the ram to the press
bed keyholes. Once secure, carefully raise the ram so that any slack
is drawn out of the chains. Once tension is put on the chains, carefully
remove the linchpins and hardened pins securing the press bed to
the rail assembly. With the pins removed, carefully extend the cylinder
to lower the press bed to the desired position. Insert hardened pins,
re-install lynch pins, and remove lift chains and lift ring hardware to
complete the press bed change.
Loading / Supporting / Securing Material
Examine the material to be worked. Understand irregularly shaped
materials and be prepared to adequately and safely support them
through the pressing cycle. Utilizing best practices, carefully load the
material into the working cavity of the press and support the material
on the press bed with pressing aids such as arbor plates (not included).
Utilize clamps or other security devices to hold the workpiece when
practical. Consider the security and stability of the workpiece in the
press cycle. A secure workpiece allows for both hands to operate the
machine.
Adjusting the hydraulic ram
The hydraulic ram is mounted to a rolling plate. The rolling feature
allows for precision alignment for off-center pressing applications.
Once aligned over the press site, carefully extend the ram to the press
surface and ne-tune the ram alignment. Before starting the press-
ing operation, tighten the retention bolt at the rolling cylinder plate to
secure the cylinder during the press operation.
