About Pacific Laser Systems

The PLS family of laser tools was developed to give contractors the ability to
transfer critical layout reference points for any job site task. All are self-leveling,
compact and durable laser alignment tools.

What sets PLS•Pacific Laser Systems apart from the rest? Built by contractors
for contractors, PLS tools were developed out of necessity by professionals with
over 50 years of experience in commercial and residential interior and exterior
layout. PLS founders were contractors first before becoming manufacturers of
the finest point-to-point alignment tools in the world.

Point-to-point reference means you can plumb with a PLS5 or PLS3 literally
from floor to ceiling or from 50 feet off the ground. With our PLS5, squaring or
layout of 90° angles can be done faster than ever before.

About Pacific Laser Systems

Our target market is the professional contractor who needs a dependable align­ment tool that will speed production and save money. General Contractors and
project managers use the PLS laser to check existing conditions before work
begins. They also use it to judge the work performed by subcontractors.
Subcontractors use PLS lasers for layout on the job site. As much as 25% of the
work day can be spent on layout. The PLS5 system gives square reference eas­ily and quickly. No more 3-4-5. The unique PLS cantilever design allows easy
sight of the opposing reference points and is proven to be effective in installing
curtain walls, foundations, columns, skylights, doors, cabinetry and much more.
The portability and utility of PLS lasers make them attractive alignment tools
when bubble vial levels or rotary lasers are too cumbersome or too limited to do
the job.

The PLS5 and PLS3 are registered trademarks of PLS•Pacific Laser Systems.

The PLS5 utilizes our patented technology, U.S. Patent No. 5,144,487.

Maintenance

Good care of the PLS3or PLS5is primarily common sense care. Remove the batteries from unit
if the laser is to be stored for a considerable period of time. Keep the optic windows clean using a
soft cloth or photographic grade cleaning tissue. Avoid storage conditions of prolonged heat or cold.

Plumb

To establish plumb with the PLS5and PLS3, place the #2 down beam over the mark to be
transposed. See Fig.1. The #3 up beam is exactly plumb within specification. You can
shoot plumb marks down and up, or cantilevered over the edge of a building/shaft opening
or floor track, etc. See Fig.2. Use the floor stand with your PLS5or PLS3to increase the
sight angle of the #2 down beam.

The PLS3and PLS5can quickly survey existing conditions for plumb. Use a tape
and #3 up beam. Position the laser near the structure.
Check any distance up or down the structure. It is also
possible to transpose marks from a roof or ceiling down to
the floor. Move the laser until the #3 up beam hits the edge or
center of the ceiling component to be transposed. Mark the
floor at the #2 down beam. See Fig. 2 and 3.

Checking Calibration

There are several easy methods to check the calibration and accuracy of the PLS5and PLS3.

We recommend that you check this periodically.

METHOD 1 (PLS
surface 25’-0” or more from a suitable wall or target. See Fig. 8. Point the #1 forward beam at
the wall or target and carefully mark the center of elevation. Swivel the PLS590° on its center
until the #5 right beam is over the first mark. Check to see if there is any difference in elevation
from the center of #1 forward beam and the center of #5 right beam. Repeat to check #4 beam.
At 50’-0” the difference should not be greater than 1/8.” At 25’-0” the difference should not be
greater than 1/16.”

Checking Calibration

METHOD 2 (both PLS5and PLS3) Exact Check of Level Accuracy. Find a fairly level site line
(preferably a concrete slab) 25’-0” or greater with two opposing walls. You can also use scrap
2 x 4s, for example, as targets. See Fig. 9. Place the laser about 6” from target #1, and carefully
mark the elevation of #1 forward beam on the target. Swivel the laser 180° on its center. Mark
the elevation center of #1 forward beam on target #2. Move the laser to target #2. At 6” from the
target, mark the center of elevation of #1 forward beam on target #2. Swivel the laser on its cen­ter and mark center of elevation at target #1. You now have two centers of elevation at each tar­get. Carefully measure the distance between centers of each set of marks. If the distance is the
same, the laser is exactly level. If there is a difference, subtract one measurement from the other.
This method magnifies any error by a factor of two. Therefore, divide this difference by two to find
the exact error of level. The maximum error for the PLS
maximum error for the PLS3is 1/8” at 25’-0” or 1/4” at 50’-0.”

METHOD 3 (both PLS5and PLS3) Exact Check of Plumb
Accuracy. This requires significant vertical height (mini­mum 10’-0”) and the ability to mark at that height. Place
the unit with the #2 down beam exactly centered on both
axes over a cross mark. See Fig. 10. At the surface
above, mark both axes of #3 up beam. Rotate the laser
180° and place the #2 down beam exactly centered on the
same mark. The #3 up beam should be exactly over the
first mark.

MARK

If there is a difference between mark #1 and mark #2,
the error of the plumb beam is one half that difference.

Magnetic Bracket Instructions

To use the magnetic bracket with the PLS laser:

1. Screw the 1/4 x 20 threaded knob to the mount on the base of the PLS laser.

2. Mount the PLS laser and bracket to steel studs, steel door frame, I-beams, carpenter’s

square, etc.

3. Rotate the PLS laser to desired point and make your mark.
Combine the PLS laser, the magnetic bracket, a standard steel carpenter’s framing square and one

or more clamps and you have the ability to mount the laser in unlimited ways. Clamp carpenter’s
square to concrete forms, ladders, wood studs, etc. Attach the PLS laser with magnetic mount as
described above. If you drill two small holes centered on the long section of the carpenter’s square,
the square can be attached to unfinished drywall partitions with screws or removable nails. Slide
the PLS laser up and down the mounted carpenter’s square to the precise desired height.

Pendulum Target

Use the PLS5pendulum target for a variety of time saving alignment tasks. For square: For con­sistent accuracy in establishing or checking square, use the PLS5target to transfer the laser
beam to the floor surface. To establish square, see page 8 of this manual. Always mount the

5

laser on the floor stand when establishing square. The pendulum target is designed so the

PLS
beams are best seen at this height.

For transfer of vertical lines:
To transfer vertical marks quickly and accurately to a wall:

1. Place the front of the PLS
forward beam on the mark to be transferred. (If the mark is on the
floor, place the #2 down beam over the mark.)

2. Place the target with its back flat against the wall at the desired
height and move the target until the #3 up beam is centered on
the plastic lined target.

3. Mark the top or bottom of the target arrow pins.

PLS5 System Interior - Exterior System

The PLS5 is the only point-to-point layout tool for use on both indoor and outdoor job
sites. Bright sunshine has traditionally limited the use of visible beam lasers to interior
projects. The PLS5 partnered with our laser receiver gives the contractor the ability to
accurately lay out a job site up to 250 + feet, even in the brightest outdoor conditions.

The PLS5 can also be used inside, without the receiver, for all point-to-point
alignment tasks.
