Komponenter overview

The Malco MB48A Portable Brake consists of several key components designed for efficient sheet metal bending. Familiarize yourself with these parts before operation.

Figur 1: Overview of the Malco MB48A 48-Inch Portable Brake.

• Ambolt: The stationary part of the brake against which the material is clamped. Features strengthening ribs for consistent bends.
• Apron: The movable part that pivots to create the bend. Also features strengthening ribs.
• Clampmekanisme: A cam-over style mechanism that secures the material firmly between the anvil and apron. Operated by the clamping håndtag.
• Clamping Handles: Levers used to engage and disengage the clamping mekanisme.
• Bending Handles: Levers used to pivot the apron and form the bend.
• Base Supports: The foundational elements that provide stability, allowing the brake to be placed on a flat surface or secured to a truck tailgate.

Opsætning

Proper setup ensures stable and accurate operation of your portable brake.

1. Udpakning: Carefully remove the brake from its packaging. Inspect for any shipping damage.
2. Placering: Place the brake on a sturdy, level surface. This could be a workbench, sawhorses, or a truck tailgate. The extra-wide bases provide stability.
3. Securing the Brake: For optimal stability and safety, it is recommended to secure the brake to your work surface using clamps (not included). This prevents movement during operation.
4. Optional Legs: If using the optional leg kit (sold separately), follow the instructions provided with the leg kit for proper installation. Ensure legs are securely attached and stable before use.
5. Indledende inspektion: Before first use, check all bolts and fasteners to ensure they are tight. Verify that the clamping mechanism operates smoothly.

Operation

Follow these steps for effective and safe bending of sheet metal.

1. Forbered materiale: Cut your sheet metal to the desired dimensions. Ensure the edges are clean and free of burrs.
2. Åbn Clampmekanisme: Løft clamping handles to open the clamping mechanism, creating a gap between the anvil and the apron.
3. Indsæt materiale: Slide the sheet metal into the brake, positioning it to the desired bend line. The brake can accommodate material up to 4 feet wide and any length due to its open throat design.
4. Luk Clampmekanisme: Push down firmly on the clamping handles to engage the cam-over style clamping mechanism. Ensure the material is securely clamped across its entire width to prevent slippage and ensure a consistent bend.
5. Form the Bend: Grasp the bending handles firmly and smoothly lift them upwards. Continue lifting until the desired bend angle (up to 135 degrees) is achieved. The strengthening ribs on the anvil and apron help ensure a tight, consistent bend.
6. Release Material: Once the bend is complete, lower the bending handles. Then, lift the clamping handles to release the material. Carefully remove the bent sheet metal from the brake.

Bending Considerations:

• This brake is suitable for materials such as aluminum, copper, and galvanized steel up to 22 gauge.
• It can be used for various applications, including HVAC transitions, roof flashing, and small fabrications as compact as a 4-inch square.
• For optimal results, ensure the material is clean and free of debris before bending.

Opretholdelse

Regular maintenance will extend the life and performance of your Malco MB48A Portable Brake.

• Rensning: After each use, wipe down the brake surfaces to remove metal shavings, dust, and debris. A clean cloth is usually sufficient.
• Smøring: Periodically apply a light coat of machine oil to pivot points and moving parts of the clamping and bending mechanisms to ensure smooth operation.
• Inspektion: Regularly inspect all bolts, nuts, and fasteners for tightness. Tighten any loose hardware. Check for any signs of wear, damage, or deformation on the anvil, apron, and handles.
• Opbevaring: Store the brake in a dry environment to prevent rust. If storing for extended periods, consider applying a rust-inhibiting coating to exposed metal surfaces.
• Bladets tilstand: While this brake does not have a cutting blade, ensure the edges of the anvil and apron remain clean and free of nicks or burrs that could affect bend quality.
