2. afety Information
Please read and understand all of the following instructions, prior
to using this tool. Failure to do so, may result in bodily injury.
CAUTION!
Class II Laser Product
Max. Power Output: ≤1mW
Wavelength: 640-660nm
THI TOOL EMIT LA ER RADIATION.
DO NOT TARE INTO BEAM.
AVOID DIRECT EYE EXPO URE.
ATTENTION IMPORTANT
• Read all instructions prior to operating this laser tool. Do not remove any labels from tool.
• Do not stare directly at the laser beam.
• Do not project the laser beam directly into the eyes of others.
• Do not set up laser tool at eye level or operate the tool near a reflective surface as the laser beam
could be projected into your eyes or into the eyes of others.
• Do not place the laser tool in a manner that may cause someone to unintentionally stare into the
laser beam. Serious eye injury may result.
• Do not operate the tool in explosive environments, i.e. in the presence of gases or flammable liquids.
• Keep the laser tool out of the reach of children and other untrained persons.
• Do not attempt to view the laser beam through optical tools such as telescopes as serious eye
injury may result.
• Always turn the laser tool off when not in use or left unattended for a period of time.
• Remove the battery when storing the tool for an extended time (more than 3 months) to avoid
damage to the tool should the batteries deteriorate.
• Do not attempt to repair or disassemble the laser tool. If unqualified persons attempt to repair this
tool, warranty will be void.

Measuring Reference
Range
Range is specified between a minimum 20-inches to a maximum of
165-feet with an accuracy of 1/16”. Longer ranges will be found by the
instrument but a variance in the accuracy may exist. At night or dusk
the range may be greater than during daylight or if the target has poor
reflective properties.
Target urfaces
Measuring errors may occur when aiming at surfaces composed of
colorless liquids (e.g. water), glass, Styrofoam or similar semi-permeable
surfaces. Aiming at high gloss surfaces may deflect the laser beam and
lead to measurement errors.
Hazards of Use
Be aware that errors in distance measurements may occur if the
instrument is defective or has been dropped, been misused or modified.
Note
Conduct periodic test measurements to ensure the instrument is measuring
accurately and consistently. This is most important if the instrument has
been exposed to abnormal use. Always confirm accuracy before and
during important measurements. Keep the laser distance measure optic
clean and inspect for damage.

Indirect Measurements (Pythagorean Methods)
All Calculations are based on Pythagorean Theorem a2+b2=c2.
This function allows for the measurement of hard to reach jobs.
Follow the order of the flashing line for each required measurement.
Note: For Accurate measurements the instruments distance to target
must remain constant. Using a tripod with a 1/4-20 thread will facilitate
this requirement.
