Safety
Precautions that should be followed when using any laser.
• Don't stare into the laser beam or view it directly with optical
instruments.
• Don't disassemble the laser or attempt to service it.
• Don't use the laser until you have read the instruction manual
and you are familiar with how to operate the laser properly.
U.S. OSHA requirements for operating visible lasers.
• Only qualified and trained employees are to install, adjust and operate
the laser. (see operator card included with this manual)
• Laser operators must carry proof of qualification.
• The area of a job site where a laser is being used must be posted with
a laser warning placard (included with shipments to U.S. & Canada).
• The laser should be set up above eye level and never intentionally
aimed at anyone.
• Turn the laser off when it is not being used, such as during lunch hour,
at the end of the day, or during other long breaks in the work.
Note: The L5 transmitter is a class IIIa (less than 2.5mW) laser under
the United States C.D.R.H. guidelines.
The L5 is a class IIIa laser under the 1993 IEC 825-1 laser safety
standard and the revised edition of the European Norm EN60825.
The L5 conforms to applicable EC directives regarding RFI and EMI.
The L5 complies with FDA performance standards 21 CFR subchapter J.
A laser warning placard is included with
lasers shipped to the U.S. and Canada.
It may be attached to the carrying case
- with the case visible and placed near
where the laser is being used - for
meeting job site posting requirement.

Level Alignment
The L5 Provides a precise reference
for level alignment needs such as:
• Setting concrete forms
• Grading and landscaping
• Digging footers and basements
• Checking and leveling floors
• Soffets and cut-offs
• Plug and switch heights
• T-bar ceilings
Vertical Alignment (see opposite page)
Along with its ability to project a level reference plane, the L5 has a built-
in manual vertical vial. When the L5 is in the vertical position, the vertical
vial located under the window in the control panel is used to plumb the
rotatable beam of laser light. When the plane can be used for:
• Aligning bolts and wall plates
• Layout work
• Plumbing walls and panels
• Transferring lines from floor to ceiling
• Aligning and plumbing posts and tall forms
Plumb Spot
The L5 projects a laser spot from the top
of the rotating head that can be used for:
• A reference beam at 90
º
to the rotatable
beam to assist with layout tasks.
• A self plumbed beam for very accurately
transferring points from floor to ceiling.
