Easymark/Easyjewel laser engraver

The Easymark/Easyjewel laser engravers require little maintenance but we ask you to wipe clean the internal area weekly with a damp cloth, for precious metal you may wish to add these to your reclamation bag. Use a lens cloth on the lens itself, it will become fogged by the fumes over time. Finally, the BOFA extraction and filtration unit should be tested for performance annually for H&S reasons, the paper filter can be changed and the hose can be washed out, again, recycle the particles you wash out of the pipe.
