AVOID DIRECT OR
REFLECTED EXPOSURE!
Operator and bystanders
MUST wear ANSI-approved
eye protection rated for
650 nm CLASS 3B lasers
when servicing reference
laser. NEVER look directly
into laser beam or stare at
laser contact point, or eye
injury may occur!

4. Locate (3) thumbscrews behind reference
laser used to adjust beam path through cabi-
net (see
Figure 135).
5. With help from an additional person, rotate
thumbscrews behind reference laser until
laser beam focal point matches "Correct
Focus" example in
Figure 130 on Page 79.
— If reference laser focal point is dark and
even, alignment is complete.
— If reference laser focal point is not dark
and even, repeat
Step 5.
6. G0913/G0914 Only: Align second reference
laser on opposite #1 mirror assembly.
The reference laser is a low-power, 650 nm
Class 3B red laser used as a visual indicator of
the laser beam focal point. The beam is reflected
off an anti-reflective lens, directed through the
cabinet by three mirrors, then passes through the
focus lens to the focal point (see
Figure 133).
IMPORTANT: The reference laser should only be
used as a guide and is not a suitable substitute for
verified laser beam path alignment.
