WARNINGS: (1) Before undertaking any work on the laser
marking system, remove the mains power plug.

trained engineers only.

scratching.
The lens consists of the optics retainer and the focusing lens, which has
been adjusted at manufacture.

procedure.
(2) In addition to its primary
optical purpose, the
objective, with its built-in

scanning unit. As a
result, the lens should
not be removed for any
longer than necessary.

lens. The cover is
delivered with every

screws and pull out the
lens cover together with
the lens. The lens is then held by 2-O-rings and no screws.
