Set Up
Laser Tool
• Place laser tool on a flat, stable surface.
• If using the auto leveling feature move the pendulum /
transport lock to the unlocked position. The laser tool
must then be positioned in its upright position on a
surface that is within the specified compensation range.
• The laser tool can be placed in any orientation and be
functional only when the pendulum / transport lock is in
the locked position.
Mounting on Accessories
• Position accessory in a place where it will not be easily
disturbed and near the central location of the area to
be measured.
• Set up the accessory as required. Adjust positioning to
be sure accessory base is near horizontal (within laser
tools compensation range).
• Mount the laser tool to the accessory using the
appropriate fastening method to be used with such
accessory / laser tool combination.
CAUTION:
• Do not leave the laser tool unattended on an
accessory without fully tightening the fastening
screw. Failing to do so may lead to the laser tool
falling and sustaining possible damage.
NOTE:
• It is best practice to always support laser tool with
one hand when placing or removing laser tool from an
accessory.
• If positioning over a target, partially tighten the fastener,
align laser tool, and then fully tighten.

Operation
NOTE:
• See LED Descriptions for indications during operation.
• Before operating the laser tool always be sure to check the
laser tool for accuracy.
• In Manual Mode, Self-Leveling is OFF. The accuracy of the
beam is not guaranteed to be level.
• Laser tool will indicate when it is out of compensation
range. Reference LED Descriptions. Reposition laser tool to
be closer to level.
• When not in use, please be sure to power OFF the laser
tool and place the pendulum lock in the locked position.
Power
• Move the power switch (See figure C) to the unlocked
position to turn the laser tool ON.
• To turn the laser tool OFF, move the power switch (See
figure C) to the locked position.
Mode
• All beams are activated when the unit is powered on.
Self-Leveling (See figure
)
C
•
When the pendulum lock on the laser tool is
switched to the on/unlocked position the unit is in
self-leveling mode.
Applications
Plumb / Point Transfer
• Establish 2 reference points that need to be plumb.
• Align either the down laser beam or the up laser beam to a
set reference point.
• The opposing laser beam(s) will be projecting a point which
is plumb.
• Position the desired object until the laser beam is aligned
with the second reference point that needs to be plumb
with the set reference point.
Level / Point Transfer
• Use front laser beam to project level reference point out
to desired object.
• E stablish 2 reference points that need to be level.
• Align the front beam laser to a set reference point.
STHT77342
• With a tripod or other stationary object, rotate the laser
unit to project the front laser beam to a new location.
• The laser point at the new location will be level with the
first point.
• Position the desired object until aligned with the laser
point.
Accuracy Check and
Calibration
NOTE:
• The laser tools are sealed and calibrated at the factory to
the accuracies specified.
• It is recommended to perform a calibration check prior to
its first use and then periodically during future use.
• The laser tool should be checked regularly to ensure its
accuracies, especially for precise layouts.
• When performing the accuracy checks, use the largest
area / distance possible, closest to the operating distance.
The greater the area / distance, the easier to measure the
accuracy of the laser.
• The lock must be in the unlocked position to allow
the laser tool to self-level before checking the
accuracy.
