Extinguished LED means the normal working state, and
the laser line will flash if out of the self-leveling range
Lighted LED means the laser is in the Tilt “Manual
Mode”. This turns off the out of level indicators
(sound and flash) and allows the operator to tilt the

6. Operating Instructions
Battery Installation
Note: Always check to be sure that the on/off switch is in the off
position before removing and replacing batteries.
1. Open the battery-box cover and put in the battery pack into the
battery case according to polarity marked in the battery-box.
2. Snap the battery cover back on.

Power Adapter Usage
By connecting to the adapter, without the battery pack, the outlet LED
light will turn green and the instrument will be powered by the
adapter. If the rechargeable batteries are in the battery box, they
will be charged in this way and the
outlet LED light will be red in the
course of charging. When the LED
light turns green, the
batteries are fully charged.
Power on/off
With the rechargeable batteries or the adapter connected, turn the
on/off switch clockwise, the power LED will light and the instrument
will project a green laser cross beam (as shown below). By turning
the on/off switch counter-clockwise, the power LED will go out
and the instrument will be powered off and the compensator will be
locked in place.
Note:
• Pay attention to the polarity of the batteries.
• Do not charge alkaline batteries to avoid explosion.
• Used (discharged) batteries are hazardous waste and should be
disposed of properly.

8. Self-Check and Calibration
IMPORTANT: It is the responsibility of the user to verify the
calibration of the instrument before each use.
1. Set the instrument on a level flat head tripod centered between two walls
(marked 1 & 2) approximately 15 feet apart. (See fig. 1).
2. Point the instrument directly at wall 1. Turn the laser on and mark the
intersection of the beams as point A.
3. Turn the instrument 180 degrees so that the laser is pointed directly at wall
2. Turn the laser and mark the intersection of the beams as point B.
4. Move the instrument and the tripod so the laser is positioned approximately
2 feet away from wall 1 (see fig. 2). Level the tripod and position the
instrument on the tripod facing wall 1. Turn the laser on and mark the
intersection of the beams as point C.
5. Turn the laser off and rotate the laser
180 degrees so that it is
facing directly to wall 2.
6. Turn on the laser and mark the inter-
section of the beams as point D.
7. Measure the distance between
points A & C.
8. Measure the distance between
points B & D.
9. If the difference between points
A & C and points B & D are less
than 1/16”, your instrument is within
its tolerance.

Calibration
Re-calibration can be performed as described below.
1. Use a level to mark a horizontal reference line on the wall.
2. Power on the unit to compare the projected horizontal line with the
reference line.
3. If the projected laser line is tilted, power off the unit and lock the compen-
sator. Screw off the calibration portal screw (figure 1) Use a 3mm hex head
wrench to calibrate the unit through its side calibration hole. Insert the hex
head wrench into the instrument and into the calibration screw. Turn the
3mm hex head wrench until the projected line is level. (figure 2) Turn the
hex head wrench clockwise if the line tilts to the right and counter-clock-
wise if the line tilts to the left.
4. If the horizontal line is too high or too low take off the rubber plugs behind
the rechargeable batteries (figure 3). Using a 3mm hex head wrench turn
the calibration screws, moving one screw at a time, clockwise to lower
the line and counter-clockwise to raise the line. Adjust the line to the cor-
rect height (figure 4).
