MACHINE SETUP INSTRUCTIONS
MACHINE LOCATION
For best performance, locate the ironworker on a stable, level surface. If a level surface is not available,
level the machine as necessary. Use the built-in forklift slots located at the base of the ironworker to ease
movement of the machine. Leave enough room around the machine to ease material handling while
operating and ensure the area is well lighted for maximum safety conditions.
MACHINE PREPARATION
The machine is delivered in one of four (4) different configurations. Check your packing list for the item
number ordered.
1. Remove all protective shipping material from:
a. Bar Blades
b. Angle Blades
c. Angle Plunger
d. Punch
e. Cylinder
2. Inspect the ironworker for damage that may have occurred during shipment. If damage is found,
notify the shipper that made final delivery immediately. They are solely responsible for all
shipping damages.
3. Locate the punch and dies (snap ring attached) and install the Punch and Die assembly; refer to
Punch Installation.
IMPORTANT: Modifications made to the machine not authorized by Uni-Hydro, Inc., shall serve
as just cause for all warranty to be voided.
ELECTRICAL CONNECTIONS
NOTE: To ensure proper hook-up of your ironworker and to meet local safety codes, we recommend
that all electrical wiring of the ironworker be performed by a licensed electrician.
IMPORTANT: (3 Phase wiring hook-ups only)
If the ironworker fails to function when the start switch is first switched to ON, immediately return the
switch to OFF or hydraulic pump damage may occur. The wiring connections might be reversed causing
the motor and hydraulic pump to run counter-clockwise. Correct by disconnecting all electrical power to
the ironworker and reversing the wiring hook-up. The ironworker is running properly when the motor
shaft is rotating in the same direction as the arrow indicated on the pump.

OPERATING INSTRUCTIONS (Cont)
LUBRICATION
Use No. 2 General Purpose Lithium grease to lubricate all EIGHTEEN (18) grease fittings on the
ironworker before beginning operation. The fittings are in the following locations:
1. Punch SLEEVE
2. All pivot pins (grease every four (4) hours)
3. Above and below Angle Shear
4. Above and below arms
OPERATING INSTRUCTIONS
IMPORTANT: Never operate more than one work station at a time of the machine may be
damaged and the warranty voided.
PRE-OPERAION INSTRUCTIONS
Before beginning operation, become familiar with the contents of this manual so you understand proper
control operation, proper safety procedures and machine functions. Learn the procedures well before
starting so as to either reduce or eliminate machine downtime due to incorrect operation. Chance of
personal injury will also be minimized.
PRACTICE OPERATION
CAUTION
Always wear safety glasses during operation and use any other safety related equipment that contributes
toward prevention of personal injury.
1. Ensure others are clear of the ironworker and press the “ON” button in the switch box to start the
electric and hydraulic systems.
2. Position yourself in front of the work station and depress the foot petal at the machine base until
the hydraulic cylinder shaft extends approximately six (6) inches. Release the petal. Note the
ironworker components stop in mid-cycle and returns to normal open position when the petal is
released, a desired safety and operational factor.
3. Depress and release the petal through a dozen or more short operational strokes until you feel in
complete control of the ironworker.
4. When satisfied that the ironworker will be operated properly, refer to Operating the PRO56 Model
Ironworker section and use it as a guide to proper operation.
OPERATING THE MODEL PRO56 IRONWORKER
1. The Uni-Hydro Ironworker is designed to perform bar shearing, angle shearing, and punching of
mild steel only.

PRO56 Uni-Hydro Manual
Page - 4 -
OPERATING INSTRUCTIONS (Cont)
2. Like any machine, there are limits to the work performance of an ironworker. Maximum
operational limitations which should not be exceeded are as follows:
a. Bar Shear – flat bars of 3/8” x 14”, 3/8” x 22”, ½” x 10” and 3/4’ x 6”
b. Angle cuts – 3 x 3 x 3/8”
c. Punch – 56 ton; see schedule of punch limitations
d. Notching Station – 1/4” material
3. To avoid damage to the ironworker and voiding of the warranty, NEVER perform more than one
type of machine operation at one time.
4. Before beginning punch operation with a different size punch than previously used, refer to the
schedule listing of punch and material limitations located on the side of the machine, or on page
10 of this manual.
WARNING
To prevent personal injury, always keep hands clear of the bar shear, angle shear and punch work areas
during operation Keep bystanders away while operating and stop the ironworker before leaving it
unattended.
STROKE CONTROL ADJUSTMENT
1. Locate the stroke control handles on the left side cover of machine.
2. To limit down stroke of machine locate the appropriate handle (Decal down stroke). Rotate
handle clockwise to decrease and counter-clockwise to increase.
**This handle is the one to use for braking and specialty punching applications.
3. To limit return stroke of machine, locate the appropriate handle (Decal return stroke). Rotate
handle clockwise to decrease and counter-clockwise to increase.
NOTE: Each revolution of either handle adjusts stroke 1/16 of an inch, half turn 1/32”, etc.
PUNCH OPERATION
1. Due to manufacturing deviations, some types of mild steel may be harder than normal. Apply a
small amount of oil on the steel to help smooth the punching operation. During production
punching, apply oil to the punch and die after every 5 to 10 holes are punched.

PRO56 Uni-Hydro Manual
Page - 5 -
OPERATING INSTRUCTIONS (Cont)
2. Whenever a change of operation is performed, check for proper alignment between the punch and
punch hole in the die. Inadvertent movement of the die block may have caused punch
misalignment.
3. Always remove the punch from the ironworker whenever the punching operation is completed.
SEVER ANGLE SHEAR OPERATION
1. To avoid crooked cuts, adjust the hold-down bolt on the front of the housing so material to be
sheared is level.
2. Be sure there are no obstructions in the shearing area before beginning operation.
NOTE: The severing angle shear does not remove a slug (large amount) of material, thus material
loss is minimal.
NOTE: If the blades finish the return stroke slowly, remove the blades. Clean all slag from the
housing, coat the blades with a light film of oil and re-install; refer to Removing and
Replacing Sever Angle Blades.
NOTCHER STATION OPERATION
CAUTION Never cut less than half the width of top blade, this will cause side pressure.
1. Adjustment of table: Loosen six (6) jam nuts, back off six (6) 7/16 x 3/4 set screws. Loosen
eight (8) 7/16 x 1-1/4 locking bolts. Fine adjust clearance by running top blade down 1/32 into
bottom blades, shut machine off. Adjust 7/16 x 3/4 set screws up until clearance is the same on
both sides of the top blade. Clearance on front of notcher should be approximately .005. Lock
jam nuts on set screws. Tighten top two (2) table bolts and six (6) side bolts. Run machine up and
recheck clearance of blades.
BAR SHEAR OPERATION
NOTE: Rotate the blades as they dull so all four (4) cutting edges may be used. To help achieve
maximum protection, adjust the stroke control to match material thickness. Maximum cut
in the bar shear is:
3/8” x 14”
½” x 10”
5/8” x 6”

PRO56 Uni-Hydro Manual
Page - 6 -
OPERATING INSTRUCTIONS (Cont)
1. Rest the material to be sheared on the base of the bar shear table.
2. To avoid distortion and avoid ironworker damage, firmly secure the bar holder onto the material to
be sheared.
3. Align the scribed mark with the outer edge of the bottom blade.
4. When making maximum cuts, position the material as close as possible to the apex of the throat
opening.
MAINTENANCE
CAUTION To prevent personal injury, disconnect electrical power to the ironworker before
performing maintenance procedures. Should power be required during maintenance, take
care to protect yourself and others from injury.
PUNCH INSTALLATION
1. Loosen two (2) 3/8” bolts and swing stripper to side. Remove punch jam nut, insert punch into
one (1) inch hole, replace the jam nut and tighten securely.
2. With indentation on the die aligned with the die stand Allen screw; tighten the side set screw with
an Allen wrench.
3. With stamped die size facing upwards, insert die into die holder and tighten the side set screw with
an Allen wrench.
4. Completely loosen 1/2 x 1-1/2 inch bolts (2) securing the die block.
5. Pull knob release button at top of punch plunger up and lower handle. Adjust punch block so
punch enters die and clearance is equal on all sides of the punch.
6. Tighten 1/2 x 1/2 inch bolts (2), install stripper and place punch adjustment handle in locked
position.
7. Operate ironworker to check punch and die alignment, correct if necessary.
DOUBLE LOCKING THE PUNCH
After alignment, punches can be double locked to prevent them from turning.
1. Run the punch into the die either manually with the manual punch aligner or by starting the
ironworker. Refer to Punch and Die Alignment procedure above.
2. Facing the punch, with the punch in the down position, locate a 3/8” NC threaded hole at the front
side of the exposed punch plunger. Part # 4213
3. Install a 3/8” x 3/8” set screw (not provided) to double lock the punch shank.
