IMPORTANT SAFETY INFORMATION
Use Precautions
WARNING: When using tool, basic safety precautions
should always be followed to reduce the risk of personal
injury and damage to equipment.
Read all instructions before using this tool!
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 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.
10. Check for damaged parts. Before using any tool,
any part that appears damaged should 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.
11. Replacement parts and accessories. When
servicing, use only identical replacement parts.
Use of any other parts will void the warranty.
12. Do not operate tool if under the influence of
alcohol or drugs. Read warning labels if taking
prescription medicine to determine if your judgment
or reflexes are impaired while taking drugs. If
there is any doubt, do not operate the tool.
13. Maintenance. For your safety, service
and maintenance should be performed
regularly by a qualified technician.
14. Use fresh batteries. Weak batteries
could affect the visibility of this tool.

WARNING: The warnings, cautions, and instructions
discussed in this instruction manual cannot cover all
possible conditions and situations that may occur. It
must be understood by the operator that common sense
and caution are factors which cannot be built into this
product, but must be supplied by the operator.
Operating Instructions
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this document
including all text under subheadings therein before set up or use of this product.
General Instructions for Use
WARNING! Only turn Laser on when tool is on
workpiece. Do not stare directly at the laser beam.
Do not aim the beam at any person or
object other than the workpiece.
WARNING! Do not aim Laser at a workpiece
with a reflective surface, such as sheet metal.
Reflective sheet metal could direct
the beam back at the operator.
LCD Display Controls
1. 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.
5. ))) Sound: This button toggles the sound. When
the sound is on, the level will beep once when it
measures any 10° increment and more than once
when it reads 0° or 90°. A symbol – ))) – will
appear above the decimal point on the display and
the unit will beep to indicate that the sound is on.

Horizontal and Vertical Vial Use
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.
Laser Controls
1. Vertical Laser Button - This button turns on
the vertical laser line if the Slide Switch is in the
upper position. The vertical laser is blocked
while the Slide Switch is in the lower position.
2. Horizontal/Dot Laser Button - This button turns
on the horizontal laser line if the Slide Switch is
in the upper position. It can be used along with
the vertical laser line to make a cross. When the
Slide Switch is in the lower position, the laser is a
dot instead.
3. Slide Switch - The Slide Switch determines laser
operation.
WARNING! Point the end of the level away
from people’s eyes when adjusting the Slide
Switch. If the Slide Switch is in the lower
position, it can conceal an illuminated laser
beam.
If the Slide Switch is in the upper position, the
Vertical Laser Button will project a vertical line
and the Horizontal/Dot Laser Button will project
a horizontal line. When the Slide Switch is in the
lower position, the Vertical Laser Button will be
covered and the Horizontal/Dot Laser Button will
project a simple dot beam.
WARNING! To conserve battery power and
prevent accidents, move the Slide Switch to
the upper position and verify that both lasers
are off after use.
