OPERATING INSTRUCTIONS
1. When the Laser Level is properly positioned, turn on the Laser by rotating the
Rotation Speed Control (10), clockwise. Then, recheck the Level Vials (4, 9) to
make sure the Laser Level has not been bumped or moved.
(See Figures B and C.)
2. The rotation speed can be set by adjusting the Rotation Speed Control (10) knob.
Turn the Control clockwise to make the beam rotate faster.
Turn the Control counterclockwise to slow the beam down.
3. Mark the desired measurement. Then, turn off the Laser Level by rotating the
Rotation Speed Control (10), counterclockwise all the way. (See Figure C.)
Using the Laser Level To Equalize Height Of Distant Objects:
For example: If you wish to install cement footings for a storage shed, first deter-
mine the desired height of any one of the footings. Align the laser beam with the
top surface of the reference footing, and check to make sure the Vial Levels (4, 9)
are level with the ground. Direct the laser beam toward each of the remaining
footing locations. On reference stakes at those locations, mark the spot that the
Laser illuminates. This indicates the desired top surface of that footing. This
technique can be used for many similar applications, i.e., to align pictures on a
wall.
Using The Laser Level To Install Horizontal Or Vertical Objects:
For example: To install a chair rail on an interior wall, first mark the desired height
of the rail. Align the Laser Level with that point, and check to make sure the Vial
Levels (4, 9) are level with the floor. Shine the laser beam on the adjoining wall,
and have an assistant mark that location. Then, install the chair rail in a direct line
between the two points. This same technique can be used to install vertical or 45
degree angle objects.
Using The Laser Level To Check Slope:
For example: To determine the slope of a floor, place the Laser Level at one end
of the floor, using the Tripod (3). Check to make sure the Vial Levels (4, 9) are
level with the floor. Measure the vertical drop from the Laser Lens to the floor
surface. Shine the laser beam on a ruler held vertical at the other end of the floor.
The difference in these measurements is the amount of slope in the floor. This
technique can also be used to design slope, such as when constructing an out-
door surface which will require a runoff slope.
