Machine Operations
Edwards Hydraulic HP20T machinery is capable of many cold forming
or pressing functions. This manual outlines the basic functions associ-
ated with typical Horizontal Press operations and is neither intended to
create a comprehensive list of, nor describe every operation possible
with this versatile tool.
Horizontal Press operations are dangerous
and require extreme care and caution in the preparation of the
material being worked, the press set-up and the pressing opera-
tion.
Please refer to the following setup, safe operation and press
operation sections for an understanding of the potential hazards pres-
ent in any horizontal pressing operation.
With 20 Tons of force, the Edwards HP20T features robust engineering
and construction and is designed for years of heavy duty service when
powered by an Edwards Ironworker or Porta Power portable hydraulic
unit. Please refer to all Edwards power source manuals as well as the
Safety, Installation, Operation and Maintenance Manuals of the HP20T
prior to operation of the machinery.
Operational Precautions
Reasonable, common sense safety precautions should be observed when
operating the Ironworker or Hydraulic Accessory Tool. The following pre-
cautions are described in order of their hazard.
Electrical Hazard
Dangerous high voltages are present inside the electrical enclosure
of this product. Only quali fi ed, authorized, maintenance or service
personnel should gain access to the electrical panel.
Lockout Power
Danger, circuits are live. Lockout / tagout upstream power source
before any maintenance activity is performed.
Shear / Crush Hazard
Moving parts can cut and crush. Keep hands clear when servicing
and maintaining the Ironworker or Hydraulic Accessory Tool.
Hydraulic Fluid Hazard
Hydraulic hoses are under pressure. Pressurized fl uid can pierce
skin and cause severe injury. To avoid physical hazard, always wear
personal protective equipment when servicing / maintaining the
Ironworker or Hydraulic Accessory Tool.
Do Not Operate With Guard Removed
Physical barriers and guards have been designed and installed to
protect operator and maintenance personnel from moving parts that
can pinch, cut and crush. If it is necessary to remove guarding when
servicing your Hydraulic Accessory Tool, immediately replace guards
after service and prior to power being restored to the machinery.
