OPERATING INSTRUCTIONS
TURNING LASER BEAMS ON/OFF
Push the ON/OFF buttons for the horizontal line
1
, vertical line
2
, and plumb
spot
3
to turn ON and OFF their respective laser lines. These buttons are only active once
the Pendulum Lock/Unlock Slider Switch
6
has been set to the Unlocked position. If
the Pendulum Slider Switch is moved from the Unlocked to the Locked position while the
laser beams are active, they will be turned OFF. The different laser lines can be operated
independently or simultaneously.
NOTE: The plumb spot application projects laser beams both in upward and downward
directions. The downward beam may be used to locate a specific point on a floor layout
while the upward beam projects that same point to a ceiling.
PENDULUM SLIDER SWITCH & SELF-LEVELING
The laser assemblies are mounted on a pendulum so that the instrument can self-level. The
Pendulum Slider Switch
6
must be in the unlocked position for the instrument to self-
level. If the instrument is tilted by >4° from the horizontal plane, the pendulum will not be
capable of self-leveling; the active laser beams will flash and the Excessive Tilt Indicator
5
will blink to indicate that the instrument is not level and cannot self-level. The instrument
must be repositioned on a more level geometry for the self-Leveling pendulum to function
appropriately.
NOTE: If the instrument indicates that it is not level
(via flashing beams and/or a blinking Excessive Tilt
indicator
5
),
then it should not be used for laying
out level or plumb lines.
NOTE: Following use, the active laser beams must be
turned OFF and the Pendulum Slider Switch must be
placed in the Locked position prior to storage.
