Laser Safety
• Use the tool only with the specifically designated batteries.
• Store the tool out of reach of children and other
untrained persons. Laser tools are dangerous in
the hands of untrained users.
• Tool service must be performed only by qualified repair
personnel. Repairs, service or maintenance performed
by unqualified personnel will void the warranty. Only
approved and authorised service technicians can carry
out warranty repairs.
• Do not use optical tools such as a telescope or transit
to view the laser beam. Serious eye injury could result.
• Do not place the tool in a position which may cause
anyone to intentionally or unintentionally stare into
the laser beam. Serious eye injury could result.
• Do not position the tool near a reflective surface
which may reflect the laser beam toward anyone’s eyes.
Serious eye injury could result.
• Do not use the tool at a position where the
laser beam can cross any person at head height.
• Do not let children come in contact with the tool.
• Turn the tool off when it is not in use. Leaving the tool
on increases the risk of staring into the laser beam.
• Do not operate the tool around children or allow
children to operate the tool. Serious eye injury may result.
• Do not remove or deface warning labels.
Read the following safety instructions before attempting to operate
this product. Keep these instructions in a safe place for future reference.
WARNING! SAVE ALL WARNINGS
& INSTRUCTIONS FOR FUTURE REFERENCE.
Read and understand all instructions.

• Never look into the laser beam directly and intentionally.
• Do not use optical tools to view the laser beam.
• Do not use the tool at a position where the laser beam can cross
any person at head height.
• Do not let children come in contact with the laser.
There are no user serviceable parts inside. Disassembling the tool will
void all warranties on the product. Do not modify the tool in any way.
Modifying the tool may result in hazardous laser radiation exposure.
CAUTION!

Pythagoras measurement
• To calculate the unilateral distance of a triangle pythagorean mode
can be used. When taking measurements of the triangle, ensure the
length of the right side is shorter than the length of the hypotenuse.
If not, the instrument will display an error signal.
• To ensure the accuracy of measurement, take measurements from
the same starting point of the first order hypotenuse. Then follow
with the measurement of the right side. Please follow the instructions
according to the method required. (See Figs.5-8 to determine the
appropriate method).
1. Calculate the side of a right angle triangle (Fig.7)
Press the area / volume / pythagoras button three times to enter
pythagorean mode. Follow the instructions displayed on the screen as follows:
• Press the read button to measure the length (a) of the hypotenuse.
• Press the read button to measure the length (b) of the rectangular side.
• Length (x) will be calculated automatically with results shown on the
display screen.
