2.
  Power ON the laser tool in Self-Levelling Mode 
(Figure Ⓜ ①).
3.
  Where the Plumb Up Dot laser beam is displayed 
on the ceiling, mark point A (Figure Ⓟ ①).
4.
  Rotate the laser tool 180° on the tripod 
(Figure Ⓟ ②).
5.
  Where the Plumb Up Dot laser beam is 
now displayed on the ceiling, mark point B 
(Figure Ⓟ ②).
6.
  Measure the distance between points A and B 
(Figure Ⓟ ②).
7.
  If the distance between points A and B is greater 
than the allowable distance for the corresponding 
ceiling height in the following table, calibration is 
necessary.
Ceiling Height
Allowable Distance 
Between A & B
7.5m 4.5mm
15m 9.0mm
  If calibration is required, the laser must be 
serviced at an authorized service center. To 
locate your nearest Stanley service center go to

Adjusting the Vertical Tilt
The Vertical Tilt option uses the Adjustment Knob 
(Figure Ⓑ ①) and the level vial (Figure Ⓑ ②) to 
adjust the laser tool's base up to +/- 5° along its length.
First, lock the laser.
•  To move the laser tool's base closer to the surface 
(Figure Ⓘ ③), turn the Adjustment Knob clockwise 
(Figure Ⓘ ②). As you turn the knob, the bubble on 
the level vial will move upward (Figure Ⓘ ①).
•  To move the laser tool's base away from the 
surface (Figure Ⓘ ⑥), turn the Adjustment Knob 
counterclockwise (Figure Ⓘ ⑤). As you turn 
the knob, the bubble on the level vial will move 
downward (Figure Ⓘ ④).
Using the Detector
The Detector allows you to determine the location of 
the laser bean when distance or lighting conditions 
make the laser beam difcult to see.
Detector Setup
You can hold the Detector by hand or attach it to the 
optional clamp to mount the detector to a measuring 
rod, pole, or similar object.
Using the Detector with a Clamp
1.
  Guide the clamp onto the detector using the 
alignment holes on the clamp (Figure Ⓕ ①)and 
the back of the detector (Figure Ⓕ ②.
2.
  Turn the xing screw clockwise to tighten 
(Figure Ⓕ ③).
3.
  Loosen the tightening knob (Figure Ⓕ ④) by 
turning it counterclockwise.
4.
  Place the clamp onto a level staff, pole, or similar 
object.
