Using the manual quick coupler for mini-excavators

1. When operating the shovel, place the bucket on the ground, tilted so that the clamping screw is easily accessible.

2. Loosen the screw until you encounter significant resistance. At this point, the quick-release jaw should be fully open.

3. When operating the excavator, remove the bucket from the quick coupler by tilting it, then take the new bucket.

4. Lift the bucket off the ground for tightening.

5. Tighten the screw until the jaw is completely tightened.
