                   OPERATIONAL INSTRUCTION MANUAL FOR 3 ROLLS PLATE BENDING MACHINE:

             Proper foundation required for all type of 3 Rolls Plate Bending Machine, but PIT foundation is required for Big & Heavy duty machine.
             Do the proper Installation & Electrification after doing proper foundation.
             Fill up Oil (Of any Bharat Petroleum Brand) in Gearbox and Grease in all Auxiliary Gears before operating the machine.
             Lift up the Top roller by handling screw with given handle with equal proportionately with both the ends.
             Pre-pinch the test plate before inserting in machine to get curvature.
             Insert the test plate by squaring the plate on bottom rolls. And test plate height is to be maintained with the Bottom roller height.
             Start the lowering Top roll and rest on the test plate by moving screw from both the side equally & proportionately. Start the machine
             so it gets rolled the plate.
             Gradually increase the Top roll presser on the test plate to get the require size of the Internal Diameter of the job.

             After completing of the rolling operation lifts up the Top roll end Tighten up the lifting screw (given back side of the machine) for up the
             Top roll to facilate & help for removal of test pieces.
             Remove the non drive side end by using the mechanism given mechanical screw the non drive side end by moving clock wise and Anti
