Voltage Change on Single Operator Piranha Ironworkers
To change the voltage from 230 volts to 480 volts or 480 volts to 230 volts on single operator P-model Piranha Ironworkers, follow these 4 basic steps.

All of our Piranha Ironworkers come standard with a round bar shearing section, with the exception of the P50, which can shear round bar with an optional attachment. If you want to cut smaller sizes of round bar, different sizes of blade can be purchased from our parts and service department for the highest quality cut.

The serial number for all p-model (P-40, P-50, P-70, P-90, P-120) is located below the shear table, riveted to the lower beam. The serial number follows the model number.

Note: Machine may have either adjustment caps if a newer machine or socket-head bolts if an older model.
1. Run the machine to full up and shut it off.
2. Remove the die from the die block to avoid damage to tooling.
3. The punch should extend just past the bottom of the lower stripper foot. Hold a flat surface to the stripper foot to determine the position of the punch.
4. On newer machines, loosen the set screws on the adjustment caps. On older machines, remove the chrome caps from the adjustment bolts.
5. Turn the machine on and run it down to where the stripper foot just touches the die block. This relieves the pressure on the caps or bolts and will allow them to turn freely.
6. Adjust the caps or bolts so that half of the centering tip of the punch protrudes below the die block. Run the machine up if necessary.
7. After adjusting the punch, run the machine down again, making sure that the stripper foot touches both sides of the die block at exactly the same time. Adjust if necessary.
8. Lock the set screws on newer machines or replace the chrome caps on older machines.

P50 Piranha Ironworker Safety and Operational Guide
Disclaimer
This safety and operational setup guide is provided by Megafab, maker of the Piranha line of hydraulic Ironworkers. This guide is designed to assist the end user in safe set up, operation, and maintenance of Piranhas ironworkers. However, it should not be used as a substitute for thorough operator training.

1. Rotate the hold-down bar out of the way by removing the locknut and washer from the holddown adjustment lever above the angle block. This will expose the angle knife cover plate.
2. Loosen the two hex bolts but do not remove them, as these hold the half-moon pieces above the blade.
3. Remove the locknut from the through-bolt and remove the cover plate.
4. Remove the upper angle knife by pulling from the left and right corners.
5. The upper angle knife has a different radius on each corner. Rotate it so that the corner that best matches the angle being cut is pointed down.
6. Reinsert the knife. Make sure that it is snug against the half-moon pieces and that there is clearance on all sides of the through-bolt. This is to ensure that the through-bolt does not take the force of the shearing action, as this could damage your machine.
7. Replace the angle knife cover plate.
8. Tighten the two hex bolts until they are sung, then give them an eighth of a wrench turn.
9. Replace the locknut on the through-bolt. It should be snug, but you should still be able to move the angle knife from side to side with a minimal amount of effort.
10. Rotate the hold-down bar back into place and rethread the washer and locknut on the bolt. Do not torque the locknut. The washer should have plenty of wiggle room.
11. If necessary, watch the angle knife from the back of the machine during a test shear. The blade should find the fillet before it shears the angle. If the blade is too tight, it will start to shear before finding the fillet. If it is too loose, it may bounce between the sides before beginning the shear.

1. Slide material into the machine from the hold-down side of the machine.
a. IMPORTANT: Ensure that the material is still visible from the hold-down side of the machine before shearing. Never feed material in from the backside of the machine.
2. Move the hold-down adjustment lever to the appropriate setting.
3. Finetune the setting by adjusting the coupling nut on the swing bolt.
4. Make sure the material is firmly clamped down by the before shearing.

1. Inside the cabinet, locate the pressure gauge zip-tied to the hydraulic hose.
2. Remove the zip tie.
3. Remove the hydraulic hose cap with an 11/16 wrench.
4. Fit the pressure gauge to the hose, tightening with the 11/16 wrench.
5. Start the Ironworker.
6. Run the Ironworker to full top and check the pressure.
7. Run the Ironworker to full bottom and check the pressure.
8. Shut down the Ironworker.
9. Remove the pressure gauge and store it in a safe location.
10. Replace the hydraulic hose cap.

How to Adjust the Hold Down Assembly on the Piranha Ironworker
1. Make sure the hold-down adjustment lever is in the straight-up position.
a. Older machines have a pin rather than a lever. No adjustment is necessary.
2. Adjust the coupling nut so that it is flush with the top of the swing bolt.
3. Push the hold-down up against the coupling nut.
4. Start the machine and jog the arm down while watching the angle block as it moves down towards the table.
5. Ensure that the angle block touches both sides of the table at exactly the same time.
6. If not, adjust the nyloc nuts on the left and right sides of the hold-down adjustment lever to pull the angle block in the appropriate direction.
a. Older machines have removable chrome caps and socket head bolt. The adjustment procedure is the same.
7. Fine tune the placement of the urethane block by adjusting the coupling nut on the swing bolt.

The grease points on the Piranha Ironworker should be lubricated every 40 hours of work time, or weekly under regular usage, with the exceptions of the drive motor, which should only be greased once a year.
