Applications • L4
Level Alignment
The L4 Provides a precise reference
for level alignment needs such as:
• Setting concrete forms
• Setting grout pads
• Checking grades
• Checking base material
• Digging footers and basements
• 4ft (or 1m) marks
Vertical Alignment
Along with the ability to project a level
reference plane, the L4 has a built-in
manual vial for aligning the plane of light
vertically using the W1 accessory mount.
This plumb 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

Level Setup • On Tripod
Be sure to read the "initial setup guidelines" section (pg 6).
Using the two leveling knobs, center the bubble in the circular level vial (see
procedure on pages 2 or 3 if you have any difficulty). Facing the laser control
panel and looking down at the circular level vial, when you turn either leveling
screw clockwise, the bubble will move toward that leveling screw. Once the
bubble is centered, start the laser by pressing the power (0/l) button .
If extreme distance is required, the L4 or L4+ can be set-up in the middle of a
site, covering a total diameter of 1500 feet (460 meters) with the R7 receiver
or the MC-1 receiver.
Periodically check your setup against existing benchmarks or set and check
your own benchmarks.
