2. Keep turning the Adjusting Knobs (16)
until the Bulls-Eye Bubbles (19) oat
exactly in the center of the circle. See
Figure 5, below.
3. NOTE: The Bulls-Eye Bubbles (19)
are intended for initial leveling of the
Rotating Head (7) only. After placing
the Plastic Body (5) into the tripod slot,
further leveling should be done using
the Horizontal Bubble (4) as a reference.
See Figure 4 on preceding page.
General Operating Instructions
1. Designate a work area that is clean and
well-lit. The work area must not allow
access by children or pets to prevent
distraction and injury.
2. NOTE: The numbers indicated in Figures
6a and 6b are for reference only. The
Laser Level knobs are not numbered.
3. Set the level parallel to knobs ‘1’ and
‘2’ as shown in Figure 4a below. Adjust
knobs ‘1’ and ‘2’ until the Horizontal
Bubble (4) is in the center.
4. Turn the level 90°. It should now be over
knob ‘3’ as shown in Figure 6b below.
5. Adjust knob ‘3’ until the Horizontal
Bubble (4) is again in the center.
6. Turn Level back 90°, to the position as
shown in Figure 6b. The Horizontal
Bubble (4) should still be in the center.
If it is not, repeat the steps above. If,
after repeated attempts, the Level is still
uneven check all mountings to ensure
nothing is loose and that the Plastic
Body (5) is properly seated in tripod slot.
7. Once Laser Level is set in Tripod, you
may set the laser to the type of beam
you wish to use. The laser projects up
to 1,500 feet. Set the Lens Fixture (11)
“Down”; and this mode will x the Level
Laser beam to a beam splitter (-) mode.
The beam splitter mode will project a
horizontal line. Set the Lens Fixture (11)
to the top mode and this mode will set
the Laser Level beam to a dot. Turn the
Laser Level “ON” by pressing the “ON/
OFF” button (9).
8. WARNING! Do not point the Laser
Level at people or animals.
9. Once you have leveled the Level
Laser in the Tripod (15), you can use
it for many applications. Rotating the
Rotating Head (7) with the laser ON and
set to the beam splitter (-) mode, you
can set a line of equal height in a room
to verify alignment of pictures, electrical
plugs, or shelving. The Laser Level
