PDB files are plain text. Simply open in any text editor - so not MS Word - and delete whatever you don't need. In your case this probably means removing all HETATM lines at the end.

If you're using PyMol, you can hide the residues that you don't want to see. First, click "Display > Sequence" to see the amino acid sequence. Then highlight the residues that you want to hide. On the right, the highlighted residues will be indicated by "(sele)". Next to "(sele)", click "H > everything" to hide the residues that you've highlighted.
