Getting Started: Machine Setup

Preparing the Installation Site

• Select a Clean, Level Surface: Start by selecting a flat, stable surface for the machine. Make sure the area is clean and free of debris that could affect leveling and operation.
• Level and Anchor the Machine: Position the machine on the selected site and use a level to check its horizontal alignment. Anchor the machine securely to the floor to prevent movement during operation, which can affect seam quality and safety. Ensure the workspace is well-lit and easily accessible for power supply and machine controls.

Electrical Setup

• Power Requirements: Verify the power requirements for your specific model. Standard Pittsburgh Lock Former Machines typically require a 115-volt grounded power supply, but some models may need a 230-volt supply. Always check the machine’s specifications.
• Professional Installation: Install power outlets according to local and national codes. If unsure, consult a certified electrician.
• Safety Precaution: Disconnect the machine from the power source before any installation or adjustments to avoid serious injury.

Installing Roll Sets

• Remove Covers: Begin by removing the top cover and the rear top plate to access the shafts where the rolls are mounted.
• Select Rolls in Sequence: Rolls are usually marked with designations like "T1" and "B1" for top and bottom rolls, respectively. Install the rolls in numerical order from left to right on the entry side of the machine. The “T” rolls go on the top shaft, and the “B” rolls on the bottom shaft.
• Orientation of Rolls: Ensure the numbered sides of the rolls are facing outward. This orientation is essential for correct seam formation.
• Secure Rolls: Insert keys into the keyways of each roll and fasten them with socket head cap screws and washers. This ensures the rolls are securely in place.
• Safety Reminder: Disconnect the power before installing rolls to prevent accidents.

Adjusting Hold Downs

• Initial Setting: With the machine turned off, tighten the hold down bolts until they are snug, then loosen them by approximately 3/4 of a turn. This setting is generally effective for most stock thicknesses.
• Test and Fine-Tune:
• Run a test piece through the machine and observe the quality of the forming.
• If the stock slips, incrementally tighten the hold downs equally until slippage stops.
• If the metal curls excessively or shows pressure marks, slightly loosen the hold downs.
• Only adjust if necessary: Once the machine is running smoothly, avoid unnecessary adjustments to the hold downs.

Starting Operation

• Feeding Stock: Hold the metal stock firmly against the entrance gauge and feed it into the forming head. Maintain contact with the gauge until the trailing edge is engaged in the rolls.
• Minimum Part Length: The minimum part length is typically 7 inches. For pieces shorter than this, run a longer piece through the machine, then notch and cut it to the desired size afterward.
• Safety Checks: Before beginning production, ensure all covers are reinstalled, lockouts are removed, and the machine is powered on safely.

Safety Precautions

• Always disconnect the machine from the power source before performing any maintenance or adjustments.
• Use lockouts to prevent accidental startup during setup.
• Follow all manufacturer warnings, especially when adjusting hold downs beyond normal settings, as this can reduce the lifespan of the machine.
