OPERATION
3. Mounting accessory features
Introduction
Congratulations! You’ve just purchased a time-saving, precision laser tool of
superior quality. Laser Square is not only precise, but it’s also easy to use.
Simply turn laser square on, place it on any surface and the perfectly balanced,
self-leveling pendulum inside the device takes care of the rest. If placed on a
surface which positions the pendulum beyond its operating range indicated in
the specifications laser square’s 3 beams will blink quickly, indicating the need
for the device to be re-positioned on a more level surface. It’s that simple. So get
to work and enjoy the time-savings which laser square provides.

Turning the laser square on and off
• To turn laser square on, slide the power switch to the up position.
Note: This not only turns the laser on, but also releases the protective
pendulum lock.
• To turn laser square off, slide the power switch to the down position.
Auto-off feature
• A battery saving Auto-off feature has been incorporated into laser square
which will shut the device off automatically in 20 minutes unless overridden.
To override the Auto-off feature simply turn the device on, off, and on again
within 4 seconds. Once the Auto-off feature has been overridden, all three
lasers will blink quickly for two seconds and the device will remain on for
eight hours before turning off automatically.
Out-of-level indicator
• Laser Square is a self-leveling device which is effective only within the
specified range. If the device is not within this range all three laser beams
will blink quickly, indicating the need for laser square to be positioned on a
more level surface.
Low battery indicator
• When the battery power becomes low, all three laser beams will blink
slowly, indicating the need for all three of the batteries to be replaced.
Note: Space has been provided in the storage box for spare batteries.
Note: laser square can be used for up to 10 hours during low battery
indication before it will turn off completely.
Using the reflective targets
• The red plastic film used in the targets enhances the laser making the laser
dot much more visible. Tabs on the target allow it to be attached to a
standard tape measure which can then be used as a Storey pole.
Using the laser enhancement glasses
• The red plastic used in the glasses enhances the laser, making the laser dot
more visible. These glasses are particularly useful when using laser square
outdoors or in brightly lit environments.
Battery replacement
• Turn the slotted screw located at the back of laser square in the clockwise
direction. This will release the battery cover and provide access to the
batteries. Replace all three batteries, and then return the battery cover to its
original position following the steps illustrated on the next page. When the
battery cover is in place, give the slotted screw a quarter turn in the counter-
clockwise direction to lock the cover in place.
Note: Alkaline batteries offer the longest battery life when used in this
device.

Sliding mounting stud
• Mount laser square to the accessory using the sliding mounting stud.
• Use the sliding/rotating action of the sliding mounting stud to:
1. Cantilever laser square over the accessory.
2. Rotate laser square around the mounting stud to change the location
of the horizontal leveling beam without changing the elevation of the
beam.
1/4"-20 Tripod mount
• Use this threaded hole, located on the bottom of the accessory, to mount the
accessory and the attached laser square to a camera tripod.
5/8"-11 Tripod mount
• Use this threaded hole, which continues through the accessory, to mount the
accessory and the attached laser square to a surveyor’s tripod.
Screw mounting holes
• Use the screw mounting holes to fasten the accessory and the attached
laser square to walls with drywall screws (at least 2" long).
Strap raceways
• Use the strap raceways to fasten the accessory and the attached laser
square to objects such as pipes and wooden studs with a diameter of
approximately 6" or less.
Magnets
• Use the magnets to fasten the accessory and the attached laser square to
steel objects such as steel studs.

Laser Square contains optics which have been designed to project a cross-hair
pattern on to any surface. This pattern is intended to help the user find the
center of the projected “dot” so that it may be properly marked. Marking the
center of the dot is important as the dot’s size will change when the device is
used at different ranges. This range dependant change in dot size does not
effect the accuracy of the device and is an inherent characteristic of laser light
which exists in all laser products.

Plumb
NOTE: OTHER BEAMS HAVE BEEN OMITTED FROM ILLUSTRATION FOR CLARITY.
Plumbing a surface
1. Position laser square close to the surface to be plumbed.
2. Turn on laser square.
3. Measure distance A at a point relatively close to laser square and make a
note of the distance.
4. Measure distance B at a point further away from laser square and make a
note of the distance.
Note: The greater the distance between the two points of measurement,
the greater the accuracy.
5. Compare distance A with distance B. If distance A equals distance B, then
the surface is plumb. If distance A does not equal distance B, then the
surface is not plumb and should be corrected.
8. Laser Square applications
Use the laser offset information provided in the illustration below to speed
plumbing, squaring and leveling operations.

Level
NOTE: OTHER BEAMS HAVE BEEN OMITTED FROM ILLUSTRATION FOR CLARITY.
Leveling
1. Adjust the height of laser square using the mounting accessory or a tripod
so that the horizontal beam hits a reference point (labeled A in this
illustration).
2. Rotate laser square around its mounting axis to position the leveling beam at
a point of interest (labeled B in this illustration).
Note: It is possible to use the beam as a leveling instrument without
marking a line through beam locations, however, some may find it
more satisfying to mark the beam location at a variety of points and
then create a straight line through those points to achieve a level line.
Grading
1. Position laser square at the highest point of the surface to be graded.
2. Turn laser square on.
3. Measure distance A and make a note of the distance.
4. Measure distance B at distance X away from A and note these distances.
5. Slope=(B - A)/X
Note: To calculate Pitch, set X equal to 12". "

Square
NOTE: OTHER BEAMS HAVE BEEN OMITTED FROM ILLUSTRATION FOR CLARITY.
Squaring
1. Position laser square in the corner of the two surfaces to be squared (as
illustrated).
2. Turn laser square on.
3. Measure distance A at a point relatively close to laser square and make a
note of the distance.
4. Measure distance B at a point further away from laser square and make a
note of the distance.
Note: The greater the distance between the two points of measurement,
the greater the accuracy.
5. Compare distance A with distance B.
6. If distance A equals distance B, proceed to the next step. If distance
A does not equal distance B, then adjust the position of laser square until
distance A does equal distance B and proceed to the next step.
7. Measure distance Y at a point relatively close to laser square and make a
note of the distance.
8. Measure distance Z at a point further away from laser square and make a
note of the distance.
Note: The greater the distance between the two points of measurement,
the greater the accuracy.
9. Compare distance Y with distance Z.
10. If distance Y equals distance Z, then the two surfaces are square. If
distance Y does not equal distance Z, then adjust the position of the
surface which these distances relate to until distance Y does equal
distance Z.
Note: The plumb beams can also be used in operations such as
squaring window frames.
