MAINTENANCE

This Green Auto Leveling Rotary Laser Level has been designed to be a

low-maintenance tool.

However, in order to maintain its performance, you must always follow these simple

directions.

 Always handle the level with care. Treat it as the fine optical device it is and as

you would treat a camera or binoculars.

 Avoid exposing the level to shock, continuous vibration, or extreme hot or cold

temperatures.

 Always store the level indoors. When not in use, always store the tool in its

protective case.

 After you have finished using the level, always make sure that the level has been

turned off.

 Always keep the level free of dust and liquids. If needed, only use a soft cloth or

cotton swab and glass cleaner to clean the laser emitting window.

 Always wipe clean and thoroughly dry the level after each use.

 Check the batteries regularly to avoid deterioration.

 Always remove the batteries from the level, remote control and detector if they

are not going to be used for an extended period of time.

 Always replace the batteries when the battery icon shows empty.

 Do not disassemble this green rotary laser level. This will not only void the

warranty, but could expose the user to hazardous radiation exposure.

 Do not attempt to change any part of the laser lens.

 Tool service must be performed only by an authorized service center. Service or

maintenance performed by unqualified personnel could result in risk of injury.

CHECKING ACCURACY AND CALIBRATION

This Green Auto Leveling Rotary Laser Level is a sealed level and is calibrated to

precise accuracies at the factory. However, a calibration check is recommended

before the initial use of your laser, and then periodically from that point forward.

Be sure to allow enough time (up to 60 seconds) for the level to completely

self-level before each check.

CAUTION: When performing a calibration, always use the remote control to

adjust the level, pressing buttons on the level will bring small movements to the

accurate electronic vials inside and result in incorrect calibration.

Checking Accuracy -X Axis

1. Mount the Green Auto Leveling Rotary Laser Level on a tripod or to a level,

sturdy surface and place it approximately 100 feet (30m) away from a wall.

Face the display toward you and “X+” to the target wall (Fig. 30 and Fig. 31).

2. Press the

”button to turn on the Green Auto Leveling Rotary Laser Level

and allow the tool to self-level. Draw a plumb line on the wall; mark the

intersection of the plumb line and the laser beam as “A”.

3. Loosen the Green Auto Leveling Rotary Laser Level from the tripod and

rotate the Green Auto Leveling Rotary Laser Level 180°. Ensure that the

height of the tripod does not change, as this will affect the results. Secure the

Green Auto Leveling Rotary Laser (Fig. 32).

Fig. 31

Fig. 30

4. Allow the tool to self-level. Mark the intersection of the plumb line and the

laser beam as “B”. No adjustment is necessary if the vertical difference

between A and B is less than 1/4” (6.5mm)

Repeat the above steps to ensure a correct reading. If the distance is greater

than 1/4”, you will need to calibrate the X axis.

Calibration- X Axis

1. Keeping the Green Auto Leveling Rotary Laser Level in its current position,

turn the power off; turn the display toward you, and make X+ facing the target

(i.e. wall, detector), as shown in Fig. 30 and Fig. 31..

2. Turn on the level and remote control, press the “

” and “ ” button at

the same time to activate calibration mode.(Fig. 33a)

access the X axis for calibration (Fig. 33c).

WARNING: A wrong choice of other options may result in error. Press the back

button

to exit and re-choose the correct option.

4. You must raise or lower the beam to center it between points A and B on the

target. The level will react to “+” and “-“ input within the X+ quadrant.

If A is above B, press the

button on the remote control to move the

laser beam downward.

If A is below B, press the

button on the remote control to move the

laser beam upward.

NOTE: The parameters displayed on the display on the Green Auto Leveling

Rotary Laser Level can be ignored when performing the adjustment.

Checking Accuracy and Calibration- Y Axis

To check the Y axis, mount the Green Auto Leveling Rotary Laser Level l on a

tripod and place it approximately 100 feet (30m) away from the wall, with the Y+

quadrant facing the wall (Fig. 31); follow steps 2 through 4 of “Checking
Accuracy -X Axis”. Calibration as in “Calibration- X Axis”, choosing the “Yad” to

calibrate and adjusting “+” and “-“input as necessary within the Y+ quadrant (Fig.

34a and Fig. 34b).

Checking Accuracy - Z Axis

1. To check the Z axis, place the Green Auto Leveling Rotary Laser Level on its

back (display facing up), 100 feet (30m) from a wall on a flat, level surface

(Fig. 35).

2. Hang a plumb line down the wall at least 8 feet long.

3. Press the
