Safety Warnings and Precautions

WARNING: When using tool, basic safety precautions should always be followed to

1. Keep work area clean. Cluttered areas invite injuries.

2. Observe work area conditions. Don’t expose to rain. Keep work area well lit.

3. Keep children away. Children must never be allowed in the work area. Do not let

them handle the Laser Level.

4. Store idle equipment. When not in use, tools must be stored in a dry location to

inhibit rust. Always lock up tools and keep out of reach of children.

5. Use the right tool for the job. There are certain applications for which this tool was

designed. Do not modify and do not use this tool for a purpose for which it was not
intended.

6. Never direct the laser beam into the eyes of any person or animal. THIS MAY
CAUSE SEVERE INJURY TO THE EYE. Do not look into the beam during operation.
Make certain to switch the Laser Level to “OFF” when making adjustments or
changing the batteries. Laser light, when reflected off a mirror like surface can cause
serious eye damage.

7. Only use the type of battery recommended in this manual. Use only “AAA”
batteries for the Laser, and a 9V battery for the digital display. Do not mix old

Operation

Refer to the Assembly Drawing on Page 6.

Using the Horizontal and Vertical Vials (9 and 10).

The vials on the level can be read by observing the bubble within. If the bubble is
centered in between the lines, then the Vial is level.

Using the level with the Laser.

1. Before each use, press the Calibration Button (7) and hold it for a few seconds until

the display reads Zero. You may use a known level surface or another level to assist
you with Zero calibration.

Each Button on the unit functions as listed below:

On/Off Button (4) - This button turns on and off the LCD (3).

Preset Angle Button (5) - Pressing and holding down this button will lock the digital

reading in the display, making it easy to move the level to get a closer look at the
reading.

Gradient Button (6) - This button translates degree reading into a percentage from
Zero to 100 percent. When the degree is within 0 to 45, the percentage will be the
degree measured, divided by 45. When the degree is within the range between 45
and 90, then the percentage will be 90 minus the degree measured, divided by 45.

Hold/Display Button (8) - This button has two features. First, if you push the button
for one second, it allows the Level to emit an audible beep when the level is either at
zero or ninety degrees. Secondly, if you hold the button down for five seconds, it will
light up the display.

Laser On/Off Button (12)

Switch (18). If the Slide Switch (18) is in the upper position, the upper button will
project a vertical line and the lower button will project a horizontal line. When the
Slide Switch (18) is in the lower position, the upper button will not project a laser
beam, and the lower button will project a simple dot beam. See FIGURE 1 below.
