ð Before performing maintenance work, secure
the laser from being switched on again (key
switch OFF, remove key, main switch OFF).
ð Inform all concerned persons of the mainte-
nance work taking place.
NOTICE
Damage to the fiber due to soiling of the quartz-block
end face
Soiling of the quartz-block end face of the fiber con-
nector can lead to high stray light values during laser
emissions and loss of laser output power. In addi-
tion, this can cause burning on the quartz-block end
face as well as overheating and damage to the optics.
Such damage is NOT covered by the warranty.
ð Check the quartz-block end face for soiling be-
fore connecting the fiber connector to the op-
tics.
ð
Clean the quartz-block end face, if necessary.
Before inserting the fiber in the optics (e.g., during installation, fiber or
optics replacement), the fiber connector must be checked for contami-
nation and cleaned as required.
