Matters needing attention in work:

1. The file is a right-handed tool and should be placed on the right side of the vice. When placed on the vice, the handle of the file should not be exposed outside the vice table, so as to avoid touching the ground and hurting the foot or damaging the file.

2. Useless files with handles or files with cracked handles cannot be used.

3, when filing, the file handle can't touch the workpiece, so as to avoid accidents caused by the file handle falling off.

4. Don't blow iron filings with your mouth to prevent iron filings from entering your eyes. You can't touch the filed surface with your hands.

5. The file shall not be used as a crowbar or hammer.
