Reasonable, common sense safety precautions should be observed
when maintaining the Ironworker or hydraulic accessory tool. The fol-
lowing precautions are described in order of their hazard.
Electrical Hazard
Dangerous high voltages are present inside the electrical enclosure
of this product. Only quali 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.
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 the operator/maintenance personnel from moving parts
that can pinch, cut and crush. If it is necessary to remove guarding
when servicing the Ironworker, immediately replace guards after ser
vice and prior to power being restored to the machinery.
Refer to Manuals
For safe installation, operation and maintenance of the machine,
read:
Installation Manual
Safety Instructions Manual
Operations Manual
Maintenance Manual
Wear Personal Protective Equipment
To avoid physical hazard wear protective eyewear, clothing, gloves,
footwear, head-gear and hearing protection.
Slipping, Tripping and Falling
During routine maintenance hydraulic uid could spill outside of the
machine footprint. Plug hose ends when working with hydraulic
uids and clean up spills near the machinery in a timely manner.
Your Edwards Ironworker will bene t from reasonable care and
periodic maintenance. Reasonable care includes daily visual
observation, general maintenance daily, weekly, monthly and at
hourly milestone intervals by operator/maintenance personnel.
Perform inspections and maintenance of the electrical, hydrau-
lic, and mechanical systems of the Ironworker and any optional
Edwards hydraulic accessory connected to the Ironworker as
follows:
Daily/Shift Change Visual Observation
Electrical System
Visually inspect incoming power and exposed surface conduit or cabling
on the Ironworker for signs of damage. Cut, abraded or crushed electrical
cords may present an electrical hazard to the Operator and damage the
machinery. Replace fuses as necessary with same type and rating.
See Figure 1 below.
Hydraulic System
Visually inspect exposed or surface mounted hydraulic hoses and t-
tings for signs of damage. Cut, abraded or crushed hydraulic hoses or
leaking ttings may present a hydraulic uid hazard to the Operator
and damage the machinery.
Plug hose ends when working with hydraulic uids and clean up spills
near the machinery in a timely manner to reduce the likelihood of
spills, trips and falls.
Mechanical System
Visually inspect guards and material hold-downs protecting moving
parts. Guards and material hold-downs must remain on the machine
for safe operation. Clear any material obstructions at the work stations
prior to visually inspecting moving parts of the machine. Cycle the
machine. Machine should operate smoothly in hydraulic extend and
retract mode.
Observe mechanical operating clearances. Punches, dies, angle shear,
notcher and bar shear blades should be evenly gapped and free of
nicks, chips or burrs in their surface.
Ironworker operation creates small concussive shocks and vibration
that may loosen hardware and fasteners over time. Inspect fasteners
and ttings and tighten where loose.
