CHECKING THE PLS480 ON THE JOB SITE
USING PYTHAGORAS 3-4-5 TRIANGLE:
Set up over the center of PEG (A) using the
plumb down laser dot.
Using one of the 90 degree beams put PEG (B)
in the ground at an exact distance of 15M/45 FT
from PEG (A).
Using the other 90 degree beam, put PEG (C)
in the ground at an exact distance of 20m/60 FT
from PEG (A).
Now measure with a tape diagonally from
PEG (B) to PEG (C). The distance should
be 25M/75FT.

This product is warranted by PLS ·Pacific Laser
Systems to the original purchaser to be free from defects
in material and workmanship under normal use for a peri-
od of three years (USA only) from the date of purchase.
During the warranty period, and upon proof of purchase,
the product will be repaired or replaced (with the same or
similar model at our option), without charge for either
parts or labor, through PLS. The purchaser shall bear all
shipping, packing and insurance costs. Upon completion
of the repair or replacement, the unit will be returned to
the customer, freight prepaid. The warranty will not apply
to this product if it has been misused, abused or altered.
Without limiting the foregoing, battery leakage, dents or
gouges to the plastic housing, broken optic windows,
damage to the switch/LED membrane are presumed to
result from misuse or abuse. Tampering with or removal
of the caution or certification labels voids this warranty.
Neither this warranty nor any other warranty, express or
implied, including implied warranties of merchantability,
shall extend beyond the warranty period. No responsibil-
ity is assumed for any incidental or consequential dam-
ages. This warranty gives you specific legal rights, and
you may have other rights which vary from state to state.

TO CHECK LEVEL:
Choose two interior walls approximately 15’-0”
apart (see Fig. 1). You can use 2 x 4s for targets.
Tu r n o n t h e P L S 4 8 0 t o L e v e l s e t t i n g # 1 ( l e v e l ) .
With the PLS480 six inches away from and facing
target #1, carefully mark the center of the line.
Label this mark A1. Swivel the laser 180 degrees
and mark the center of the line on target #2. Label
this mark B1.
Move the PLS480 six inches away from and
facing target #2. Carefully mark the center of the
line. Label this mark B2. Swivel the laser 180
degrees and mark the center of the line on target
#1. Label this mark A2.

target. Carefully measure the distance between
centers of each set of marks. If there is a differ-
ence, subtract one measurement from the other.
This calibration method magnifies any error by a
factor of two. Therefore divide any difference by
two to find the true error.Your PLS480 should have
an error of no greater than 1/8in. within 60ft.

Place the PLS480 on the standard floor
base and position the PLS480 so that the
down point is visible on the floor. Mark the
down point position and without moving
the laser also mark the intersecting point
at which the two vertical lines meet on
the ceiling.
Turn the laser 180 degrees and place the
down point on the original mark on the
floor. The intersecting point on the ceiling
should match the original ceiling mark.
If there is a difference between the
original ceiling mark and second mark,
the error of the plumb beam is half
that difference.
We recommend that you check your PLS480
periodically in order to assure its accuracy.
