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 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 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 benet 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.
Maintenance Precautions Maintenance Schedule
Failure of any element of the daily/shift change visual obser-
vation will require maintenance of the affected Ironworker or
accessory componentry. Please follow the following mainte-
nance procedures.
General Maintenance - Daily
Lockout power to machine.
Clean your Ironworker daily with a compressed air nozzle and
soft cloth lighly moistened with a mild, water based detergent
solution. Remove lings, dirt, dust and grime and excess lubricant
from working surfaces. All clean surfaces must be fully dry before
powering up machine.
Grease all machine guides and pins supplied with a GREASE
DAILY designation with NLGI Grade 2 (NLGI Service GC-LB) or
equivalent premium, heavy duty lubricant.
General Maintenance - Weekly
Lockout power to machine.
Check blade tolerance. Maintain .010 clearance between xed and
movable shear blades on 40, 50, 55, 60 and 65 Ton models at all
times. Maintain .015 clearance between xed and movable shear
blades on 75, 100, 100D, 120 Ton. 110 Elite and 110/65 DO Elite
models at all times. Insert a feeler gauge between xed and mov-
able blades to verify proper blade clearance and shear tolerance.
Adjust tolerance of shear blades by relieving the locking nuts that
secure the gib-pins to the Ironworker frame. Once loose, rotate gib-
pins to push the operating center against the frame. Gap the angle
and bar shear blades with the specied clearance and tighten the
gib-pin lock nuts. Failure to maintain proper clearance will result in
lower quality cuts, damage to blade, blade pockets and the poten-
tial to damage the Ironworker frame.
General Maintenance - Monthly
Lockout power to machine.
Check gib-pins for lubrication and snugness to the operating cen-
ter. Tighten gib-pins and locking nuts to maintain blade clearance
as indicated above. Gib-pins are wearing parts. Order replacement
gib-pins through your Edwards Distributor or through Edwards Mfg.
Co.
Check the ISO Viscosity 46 hydraulic uid level monthly. maintain
the correct volume of hydraulic uid in the reservoir as indicated.
Contaminated uid will compromise your cutting operation.
General Maintenance - First 30 Hours
Lockout power to machine.
Replace the oil lter on your Ironworker after your rst 30 hours of
use. External oil lters are available through your Edwards Distribu-
tor or Edwards Manufacturing.
When working on the hydraulic power plant use plugs to cap hose
ends during maintenance procedures to minimize uid loss. Clean
up spills near the machinery to reduce the likelihood of slips, trips
and falls.
General Maintenance - Every 1000 Hours
Lockout power to machine.
Replace the oil lter on your Ironworker after your rst 1000 hours
of use. External oil lters are available through your Edwards Dis-
tributor or Edwards Manufacturing.
When working on the hydraulic power plant use plugs to cap hose
ends during maintenance procedures to minimize uid loss. Clean
up spills near the machinery to reduce the likelihood of slips, trips
and falls.
General Maintenance - Every 5000 Hours
Lockout power to machine.
Drain used hydraulic uid, dispose of according to local or jurisdic-
tional guidelines and replace with ISO Viscosity 46 hydraulic uid
to the volume specied on the hydraulic uid reservoir.
