SAFETY The purpose of the safety section of this manual is to inform operators and maintenance personnel of the precautions to be taken while operating or servicing the machine. The following are a few basic guidelines to follow, but as with any type of machinery good judgment and a safe attitude should be applied at all times. 1. Always wear safety clothing, including eye protection and protective footwear, while operating or servicing the machine. 2.
INSTALLATION RECEIVING Use caution in handling and moving the brake. The brake weighs 550 pounds and is top-heavy. Handling should be performed with proper equipment such as a fork lift. Do not insert forks between the pallet and the bottom of the brake. INSTALLATION Locate the brake in a well-lighted area on a solid level work bench capable of supporting 550 pounds. The bench should generally be secured to the floor by bolts or lag screws.
ASSEMBLY The brake requires only minor assembly for proper operation. Place the counterweight in the tube on the apron assembly’s left end so that the apron is balanced. Tighten the two set screws in the tube to secure the counterweight in place. Secure the counterweight in place by tightening these two set screws.
MACHINE SET-UP PRECAUTIONS: 1) Read and understand the safety instructions on page 3 of this manual before proceeding. 2) Always adjust the clearance and clamping pressure for different thicknesses of material. 3) Always bend short pieces of material in the center of the brake in order to equalize the stress and avoid damage to the brake.
For the following adjustments, use test strips of metal, each approximately 3 inches by 3 inches, of the thickness being formed. When bending use the longer bend fingers and leaf fingers, as the material allows. Step 1: Clamping Pressure Check clamping pressure by clamping test strips in the brake approximately 3 or 4 inches away from each end of the brake. Clamping pressure should be enough to keep the material from slipping during a bend. It is not desirable to use excessive clamping pressure.
Step 2: Allowing for Metal Thickness The clamp assembly must be adjusted to allow for clearance according to the thickness of the material being worked. To adjust the clearance on the clamp assembly, slightly unclamp the clamp handle, loosen the bracket lock handle and turn the adjusting bracket screw. When the correction is made, retighten the bracket lock handle. Move the clamp back from the apron at least one and one half times the thickness of material being formed when forming up to 18 gauge (.
OPERATION Your brake is a general purpose tool for bending and forming sheet metal. The brake is operated in the following manner. The clamp of the brake is opened by pushing the clamp handles toward the rear of the brake. Insert the material to be bent into the opening between the clamp and table assembly and clamp the material in place by pulling the clamp handles forward. Raise the apron to bend the material to the desired angle.
Over-bending Check end-to-end alignment by clamping two test strips in the brake, about 3 or 4 inches away from either end of the brake. Bend to about 90 degrees, and see if they appear to be bent to the same degree. Remove them from the brake and stack one inside the other. Compare the sharpness of the radius. If one test strip is over-bent or has a sharper radius, move the end of the clamp which that strip came from back slightly.
