SQUARE (Fig. 3)
Place the unit on the floor or a fairly level surface near the walls or the objects to be squared.
Measure from one wall to the laser beam at two points. One point near the unit and at another
point farther away. Rotate the unit until the two measurements are equal. Do not move the unit
until the rest of the measuring is completed. Now take two measurements from the other wall to
that laser beam. If the measurements of these two points are the same, then the walls are square.
If they are not equal, move the second wall until the two measurements are equal.
You can also square vertical surfaces to horizontal surfaces by using a plumb beam and a
level beam.
LEVEL (Fig. 4)
Set the unit on a surface that is at a convenient height for marking a level reference plane on walls
or other surfaces. Mark the laser dot's location. You can now turn the unit to move the laser dot to
another location and continue marking. These marks can be connected together with a straight
edge to give you a level line.
Be careful not to change the height of the unit during the process or your level line will vary
in height.
For damages caused by usage other then intended, the user is responsible.
INSTALLING BATTERIES
Open the battery cover. Slide the battery compartment open.
Remove used batteries. Place fresh batteries in the compart-
ment, aligning them according to the label
Check for correct polarity.
Extreme temperatures and the use of batteries with different
levels of charge can reduce the operating time of
the instrument.
Always use batteries with the same power rating and from the
same manufacturer.
