Standardized Installation Procedure for Double Axis Shredder Blades： 1. Safety Precautions   Turn off the power and lock it before starting. Put on cut-proof gloves and safety glasses. Get the needed tools: adjustable wrenches, thickness gauges, and rubber hammers. Clean the blade rod and nearby areas. 2. Installation Protocol   Examine the replacement blades for edge damage. Verify all positioning pins, retaining screws, and shaft threads show no deformation or wear.   Position the blades as outlined in the instructions. Clamp the blades firmly onto the shafts and align them with a uniform tooth-and-groove pattern. Tighten screws evenly to the specified torque (usually 80–120 N·m) using a crisscross pattern.   Gauge the gap with a thickness gauge: select 0.2–0.3 mm for hard items and 0.1–0.2 mm for soft ones. Ensure the gap remains constant; reset it if it exceeds 0.05 mm.   Rotate both rods by hand at least once. The blades must move smoothly and quietly—never stick, scrape, or resist—before proceeding. 3. Operational Validation and Commissioning   Run the machine without any load for three minutes at its usual speed. Watch that it stays steady: there should be no shaking, loud rubbing, or odd movements. Next, cut a sample of material under careful watch. Check that the finished size of the pieces meets the rules (for example, D90 must be less than or equal to the target level); only after this test should the machine be approved for normal work. 4. Critical Safety and Performance Notes   Never place gloved hands near rotating components—even during manual rotation.   Keep electrical power isolated until all fasteners are fully torqued, and you verify final clearance.   If the gap is not correct, blades will wear faster, get too hot, cut poorly, or cause jams in the material feed.
