How to Use the Laser System

Powering the Laser

Batteries
Installing Batteries

Open the battery door using your fi ngers, a coin or a screwdriver.
Insert batteries into the housing so that the negative poles are toward the bigger battery spiral spring.
Push down on the battery door until the latch “clicks” into position.

Laser Setup

Position the laser horizontally or vertically (tripod mount and rubber feet downward!) on a stable platform, wall
mount or tripod at the desired elevation. The laser recognizes automatically whether it is used horizontally or
vertically when switched on.

Note: The laser always operates in MANUAL mode in the Vertical position.

Turning On/Off the Laser

Press the power button 1 to turn on the laser.

Note: The laser always powers up in the automatic self-leveling mode. The LEDs (2, 4 and 5) are

turned on for 2 seconds.

The laser is level when the leveling indicator 4 is no longer fl ashing (once every second).
For the fi rst fi ve minutes after the laser self levels, the LED 4 lights solid. After fi ve minuts the LED 4 starts
fl ashing every four seconds to let you know the laser is still level while conserving battery life.
If the laser is positioned beyond it´s self-leveling range of ±8%, the laser beam, and manual and leveling
indicators fl ash simultaneously. Turn the unit off, reposition the laser within the self-leveling range and turn
it on again.

Note: If the laser is out of its self-leveling range and remains out of it for more than 10 minutes, the
unit shuts down completely.

Note: After the laser has been level for more than 5 minutes in horizontal mode,
the HI (height of instrument) alert activates. If the laser is disturbed (tripod bumped,
etc.) so that when it re-levels the laser beam elevation changes by more than 3 mm
(1/8 in.), the HI alert shuts down the laser and rotor, and the red LED fl ashes two times per second
(twice the manual-mode rate). T o restore level, turn the laser off and on. After the laser has re-leveled,
check your initial reference elevation.

In order to switch the laser off, press the power button again.

Activating/Deactivating Standby Mode

Standby mode is a power-saving feature that conserves laser battery life.
Press and hold the laser’s or remote control’s manual button for 3 seconds to activate standby mode.

Note: When standby mode is activated, the laser beam, rotor, self-leveling system, and LEDs shut
down, but the HI alert remains activated.

6

To let you know that the laser is in standby mode, the battery LED fl ashes every 4 seconds.
T o deactivate standby mode and restore full operation of the laser, press and hold the laser’s or remote control’s
manual button for 3 seconds.
The laser and all other functions turn on again.

Using the Manual Mode

In horizontal mode pressing the manual button on the laser or the remote control changes the laser from
automatic self-leveling mode to Manual mode. Manual mode is indicated by the fl ashing (once every second)
red LED 5.
In Manual mode (horizontal), the Y-axis can be sloped by pressing the Up- and Down-Arrow-buttons on the
laser‘s keypad or the remote control. Additionally , the X-axis can be sloped by pressing the Left- and Right-Arrow­buttons on the remote control. To resume automatic self-leveling mode, press the manual button again.
In vertical mode, the laser is always in MANUAL mode. Pressing the up and down arrow buttons align the
laser beam to the right/left side, and the left and right arrow buttons at the remote control adjust the slope of
the laser beam.
To resume automatic self-leveling mode, press the manual button again.

Using the Y- Single Slope Mode

The Manual button on the remote control toggles the unit to Manual, the Y-axis Single Slope Mode, then
Automatic Mode. T o activate the Y-axis single slope mode, press the manual button at the remote control twice.
This is indicated by the simultaneously fl ashing red 5 and green 4 LEDs (once every second).
In Y-axis single slope mode, the Y-axis can be sloped by pressing the Up- and Down-Arrow-buttons on the
laser or the remote control, while the X-axis remains in automatic self leveling mode (e.g. when setting up
sloped ceilings or drive ways).
To resume automatic self-leveling mode from Y-axis single slope mode, press the manual button again.

APPLICATIONS

General Construction

Determining the Height of Instrument (HI)

The height of instrument (HI) is the elevation of the laser’s
beam.
The HI is determined by adding the grade-rod reading to a
benchmark or known elevation.

1. Set up the laser and place the grade rod on a job-site

HI

benchmark (BM) or known elevation.

2. Slide the receiver up/down the grade rod until it shows an

on-grade reading.

3. Add the grade-rod reading to the benchmark to determine

the height of instrument.
Example:
Benchmark = 30.55 m (100.23 ft)
Rod reading = +1.32 m (+4.34 ft)
Height of instrument = 31.87 m (104.57 ft)
Use this HI as a reference for all other elevations.

Using the Y-Axis Single Slope Mode

1. Set up the laser over the reference point (A).

2. Look over the rotor to align the laser to the desired direction hub

in the axis that is supposed to be used in automatic self-leveling

mode. Turn the laser on the tripod until it is properly aligned.

3. Attach a receiver to a grade rod. Set the grade rod on the self-leveling

axis direction hub to check the laser’s elevation (B).

Note: Use this HI as a reference for checking the alignment
of the laser after setting the slope for the other axis.

4. Activate the Y-axis single slope mode by pressing the manual button

at the remote control twice.

5. Check the laser’s elevation on the slope axis directly in front of the

laser.

6. Set the grade rod on the slope axis direction hub to adjust the laser’s elevation without changing the height

of the receiver on the grade rod (C).

7. Press the up and down arrow buttons until you get an on-grade reading on the receiver.

8. Recheck the laser’s elevation in automatic self-leveling axis using the HI in step 3 (B).
If the HI has been changed, rotate the laser on the tripod until you get an on-grade reading again. Make sure,

you DON’T change the height of the receiver on the grade rod.

CALIBRATION

Checking Calibration of the Y- and X-Axes

1. Set up the laser 30 m (100 ft) from a wall and allow it to level.

2. Raise/lower the receiver until you get an on-grade reading for the

+Y axis. Using the on-grade marking notch as a reference, make a

mark on the wall.

Note: For increased precision, use the fi ne-sensitivity setting
(1.5 mm/1/16 in.) on the receiver.

3. Rotate the laser 180° (-Y axis toward the wall) and allow the laser

to re-level.

4. Raise/lower the receiver until you get an on-grade reading for the

–Y axis. Using the on-grade marking notch as a reference, make a

mark on the wall.

5. Measure the difference between the two marks. If they differ more than

6 mm at 30 m (1/4 inch at 100 feet), the laser needs calibrating.

6. After checking the Y-axis, rotate the laser 90°. Repeat the above

starting with the + X axis facing the wall.

PROTECTING THE UNIT

Do not expose the unit to extreme temperatures or temperature changes (do not leave inside the car).
The unit is very robust and can resist damage if dropped even from tripod height. Before continuing your work,
always check the leveling accuracy. See Checking Calibration section.
The laser is water protected and can be used indoors and outdoors.

CLEANING AND MAINTENANCE

Dirt and water on the Rotor/Beam Exit (Component 11) will infl uence beam quality and operating range
considerably.
Remove dirt on the housing with a lint-free, warm, wet and smooth cloth. Do not use harsh cleansers or
solvents.
Allow the unit to air dry after cleaning it.
