Installing AA Batteries
Load new AA batteries in the STHT77503-1 or
STHT77593-1 laser.
Turn the laser upside down.

batteries, making sure to position the - and +
ends of each battery as noted inside the battery
compartment (Figure
Push the battery compartment cover closed until

it snaps in place (Figure
When the laser is not in use, keep the Power/
Transport Lock switch in the left (OFF) position
(Figure ) to save battery power.

Turning the Laser On
Place the laser on a smooth, flat, level surface,

opposing wall (0º position).
Move the Power/Transport Lock switch to the

• If the laser is tilted so much that it cannot self-
level (> 4°), the laser dots will flash.
• If the laser dots flash, the laser is not level
(or plumb) and should NOT BE USED for
determining or marking level or plumb. Try
repositioning the laser on a level surface.
If ANY of the following statements are TRUE,

Accuracy BEFORE USING THE LASER for
a project.

(in case the laser was exposed to extreme
temperatures).
• The laser has not been checked for accuracy
in a while.
• The laser may have been dropped.

Checking Laser Accuracy
The laser tools are sealed and calibrated at the factory.
It is recommended that you perform an accuracy
check prior to using the laser for the first time (in
case the laser was exposed to extreme temperatures)
and then regularly to ensure the accuracy of your
work. When performing any of the accuracy checks
listed in this manual, follow these guidelines:
• 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.
• Place the laser on a smooth, flat, stable surface
that is level in both directions.
• Mark the center of the laser beam.
Plumb Dot Accuracy
Checking the plumb calibration of the laser can be
most accurately done when there is a substantial
amount of vertical height available, ideally 25' (7.5 m),
with one person on the floor positioning the laser and
another person near a ceiling to mark the dot created
by the beam on the ceiling.
Mark point P1 on the floor (Figure
1.
Turn the laser ON to display dots above, ahead,
2.
and below the laser.
Place the laser so that the down dot is centered
3.
over point P1 and mark the center of the up dot
on the ceiling as point P2 (Figure
Turn the laser 180°, making sure that the down

dot is still centered over point P1 on the floor
