OPERATION INSTRUCTIONS The mild steel capacity of the Model 36 and 52 shear is 16 gauge. Included in the manual is a standard shearing, bending, and forming conversion chart for various materials including Aluminum, Stainless, and Plastics.
The gibs should adjusted for snug yet nonbinding movement. To accomplish this, loosen all six gibb screws (36). Beginning at the right hand side of the shear, depress the foot pedal fully and lock the center gibb screw so that the cutter bar remains down. Then, gradually loosen the screw until the cutter bar returns to its upright position.
Use a marker to mark the shear bed 2 inches to the from the right side edge of the table. Next, measure over 36 inches from the right side edge of the table and make another mark. Starting at the right hand side (facing the machine) at the designated mark on the table, rotate the turnbuckle (55) until the distance between the top and bottom blades is approximately 3/8 of an inch.
