Detaching the Focus Lens
1. Move the engraving table to a distance of
approximately 4 inches (10 cm) under the
lens holder.
2. Move the laser head into the center of the
workbed and put a cloth under the lens
holder so that the lens will not be damaged
if it accidentally falls from its holder.
3. Remove the pressurized air hose by pressing down on the sleeve of the air hose connector while
pulling the tube upward.
