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 and new batteries.
8. Maintain tools with care. Keep tools clean for better and safer performance.
9. Stay alert. Watch what you are doing, use common sense. Do not operate any tool when
you are tired.

be carefully checked to determine that it will operate properly and perform its intended
function. Any part that is damaged should be properly repaired or replaced by a qualified
technician. Do not use the tool if any switch does not turn On and Off properly.

On/Off: Holding this button down for several seconds turns the LCD display on or off. The
display will automatically shut off after a period to conserve battery power.
2. Hold: This button keeps the same reading on the display, even if the level’s angle changes.
Everything on the display will flash except the number while the reading is being held. Press
the button again to stop holding the reading.
3. 0% (percent): This button switches the LCD display between displaying the angle in degrees
and displaying the angle as a percent difference from 0° or 90°.
4. Calibrate (Zero Setting): This button toggles between reading 0 at the current angle and
reading the actual angle. Press the “Calibrate” button once to change the current reading
to 0° or 0%. Press the “Calibrate” button again and hold it to restore the level to reading the
actual angle. The level will reset to reading the actual angle if it is switched off. Note:
Actual calibration of the level (changing the actual angle setting) is not done by this button
and needs to be performed by a qualified technician.

(18) is in the upper position. The vertical laser is blocked while the Slide Switch (18) is in the
lower position.
2. Horizontal/Dot Laser Button (12) - This button turns on the horizontal laser line if the Slide
Switch (18) is in the upper position. It can be used along with the vertical laser line to make
a cross. When the Slide Switch (18) is in the lower position, the laser is a dot instead.
