1. The vise should be firmly fixed on the tongs and should not be loose.

2. The vise with an anvil allows a slight hammering work on the anvil, and the other parts are not allowed to directly hit with a hammer.

3. Screws, nuts and moving surfaces should be refueled to keep oily.

4. The workpiece exceeds the jaws too long, and the bracket should be used separately to prevent the vise from being overstressed.

5. Light and soft work should be gently clamped to avoid damage and bending.

6. Bulky work should be used to clamp to avoid falling off.

7. For smooth and refined work, it can be padded with soft copper or leather to prevent damage.

8. Hold the irregular work, so that the surface of the jaws is in stable and even contact with the work.
