When replacing a bucket on heavy machinery, it is important to follow safety guidelines to prevent injury. Replace the bucket on firm, level ground and pay close attention to safety [1]. Avoid abrupt operation of the front attachment [1]. When aligning pin bores, do not insert your finger into the bores; align them visually or with a tool to prevent severe injury [1]. Hold the removed bucket in a stable condition [1].

When removing a bucket:

  1. Move the machine to a firm, level surface and rest the bucket on the ground, ensuring it is stable [2].
  2. Roll O-rings onto the bucket boss, and after removing the pins, return them to their original position [2].
  3. Extend the retaining ring and remove the pin, then pull the other pins out to remove the bucket [2].

When installing a bucket:

  1. Clean each pin and pin hole and grease sufficiently [2].
  2. Move the bucket cylinder to match the pin bores of the bucket and bucket link, then insert the pin [2].
  3. Raise the boom and slightly lift the bucket from the ground [2].
  4. Align the bucket with the pin hole of the arm, moving the arm, and insert the pin [2].
  5. Insert the pin and fix the retaining ring [2].
  6. Fit the O-ring to its normal position [2].
  7. Apply grease on the grease nipples for each pin until grease comes out through the gap between the pins and bore [2].

Also, when replacing tooth points and side cutters, apply a safety block to the bottom face of the bucket [3].
