HEAD UP AND DOWN LIMIT SETTING
The head up limit is used to restrict the distance the head travels for each stroke. It can be adjusted at any time by moving
the switch trip plate to any position on the vertical bar. The trip plate & switches are found behind the head on the drive
end near the gear box.
Head Up Limit: In order to maximize production in the automatic cycle the Head Up Limit should be set to just clear the
height of the material.
Head Down Limit: This limit is factory set and under ordinary cutting requirements should not be changed. If changed, it
may cause the machine to malfunction in the automatic cycle.
VARIABLE VISE PRESSURE (OPTION)
This option allows the operator to adjust the vise pressure. This can be valuable when cutting light structurals and tubes.
By reducing the vise pressure from the system (1200 PSI or 8274kPa) pressure, distortion of materials is prevented. The
controls are located at the drive end of the machine next to the hydraulic compartment.
