Empisal KH67 knitting machine is a standard-gauge machine with 200 needles and eight pushbuttons and a pattern center for semi-automatic needle selection and knitting patterned fabric.

The look of the needlebed, carriage, and its functions, row counter, all are identical to the Brother Profile 551 knitting machine (which, however, has four pushbuttons and not eight).

Additionally, Empisal KH67 has a knob on the right-hand side of the needlebed: probably for transposing the needle selection, similar to other Empisal and Brother pushbutton machines.

Because of this, and since I do not have a whole lot more information on the Empisal KH67 model, refer to a blog post on the Brother KH551 (for accessories) and to the article on Brother Profile 552 for operations.

Empisal KH67 has a matching ribber: Empisal KR67. I suspect that Brother KR551 ribber might work too.
