Machine Operations
Edwards Hydraulic 20 and 40 Ton Press machinery are ‘do-all’ tools
capable of many functions. This manual outlines the basic functions
associated with typical press operations and is neither intended to
create a comprehensive list of, nor describe every operation possible
with a press tool. 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 operation. Please refer
to the following setup, safe operation and press operation sections
for an understanding of the potential hazards present in any pressing
operation.
Edwards 20 and 40 Ton Presses feature robust design and construc-
tion and are designed for years of heavy duty service when powered
by an Edwards Ironworker or Porta Power portable hydraulic unit. Both
Press styles perform similar functions and require the same amount
of care in the safe installation, operation and maintenance. Please
refer to all Edwards power source manuals as well as the Safety,
Installation, Operation and Maintenance Manuals of the 20 Ton / 40
Ton Press prior to operation of the machinery.
The Press is constructed of four basic assemblies. The stationary rail
assembly holds the stationary head assembly. The press bed assem-
bly moves up and down the stationary rails and the hydraulic cylinder
assembly rolls from side to side on the stationary head. Both the roll-
ing cylinder assembly and moving press bed assembly are locked into
place prior to any press operation.
The following pages detail the proper operations procedures for
setting up and safely operating the Edwards 20 Ton or 40 Ton
Shop Press.
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 qualied, 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.
Hydraulic Fluid Hazard
Hydraulic hoses are under pressure. Pressurized uid can pierce
skin and cause severe injury. To avoid physical hazard, always wear
personal protective equipment when servicing / maintaining the
Ironworker.
Do Not Operate With Guard Removed
Physical barriers and guards have been designed and installed to
protect maintenance personnel from moving parts that can pinch,
cut and crush. If it is necessary to remove guarding when servicing
the Bender, immediately replace guards after service and
prior to power being restored to the machinery.
