WARNINGS
To ensure safe operation and service of the instrument, follow
these instructions. Failure to observe these warnings can result
in serious personal injury, re, or electrical shock. Retain these
instructions for future reference.
WARNING: LASER RADIATION. DO NOT STARE INTO BEAM.
Class 2 Laser.
• Exposing eyes to laser radiation can result in severe and
permanent eye injuries.
• NEVER look directly into the laser beam emitted by this
instrument.
• DO NOT use the instrument if it appears to be damaged.
• DO NOT modify the instrument in any way, as to do so could result
in emission of hazardous laser radiation than could result in severe
eye injuries.
• DO NOT use optical equipment such as lenses, prisms, optical
scopes, etc. to transmit, retransmit, or view the laser beam as this
could result in severe eye injuries.
• This product should not be used by untrained operators or
operators who have not read and fully understood the instructions.
• DO NOT remove warning labels from this instrument as this could
result in serious personal injury and increases the risk of exposure
to hazardous laser irradiation.
• This instrument is IP54 dust & water resistant. Following any
contact with water, thoroughly dry the instrument with a dry,
lint-free cloth.
• There are no user serviceable parts in this instrument.

TURNING LASER BEAMS ON/OFF
Set the Power/Pendulum Lock/
Unlock Switch

to the unlock
position to turn on the laser lines.
Move the Power/Pendulum Lock/

to the locked
position to turn off the laser lines.
PENDULUM SLIDER SWITCH &
SELF-LEVELING
The laser assemblies are mounted on a pendulum so that the
instrument can self-level. Set the Power/Pendulum Lock/Unlock
Switch
1
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 to indicate that the instrument is not level and
cannot self-level. The instrument must be repositioned on a more
level surface for the self-leveling pendulum to function appropriately.
NOTE: Following use, the Power/Pendulum Lock/Unlock Switch
1
must be placed in the Locked position prior to storage.

The instrument can be attached to a magnetic mounting bracket
via the 1/4-20 Tripod Mount
5
. The bracket may be magnetically
attached to any ferromagnetic structure such as steel studs, ducts,
structural beams, and steel doors. The bracket also features a
key-hole for mounting the instrument using a screw or nail to non-
magnetic structures. Once mounted to a structure via the mounting
bracket the instrument can be rotated on the bracket through 360°to
direct the laser beams.

VERIFYING ACCURACY OF LASER LINES
HORIZONTAL BEAM LEFT/RIGHT TILT
Position the instrument on the floor xdistance from front of the device to
the vertical wall as shown. Rotate the instrument on the bracket to the left
so that the right side of the beam is projected on the wall directly across
from the instrument, mark the vertical location on the wall (a). Rotate the
instrument to the right and repeat marking the vertical location of the left
side of the beam (b).
The maximum distance (delta) between aand b
is shown in the table below.

HORIZONTAL BEAM OUT-OF-PLANE TILT
Position the instrument parallel to a wall and project a beam along the
wall, from left to right as shown. Mark two locations (a, b) along the beam
separated by distance x. Position the laser at the other side of the wall and
project the beam back through mark b, from right to left as shown, and
mark position c.
