for future reference.

5.1 General safety rules

a) Check the condition of the tool before use. If the
tool is found to be damaged, have it repaired at a
Hilti service center.
b) The tool must be checked at a Hilti service center
after it has been dropped or subjected to other
mechanical stresses.
c) The tool is intended exclusively for indoor use.

hazards when used incorrectly by untrained per-
sonnel or when used not as directed.

6 Before use

6.1 Setting up the tool

1. Connect the mains adapter to the PTA 20 calibration
tool.
m) Take the influences of the surrounding area into
account. Do not use the tool where there is a risk
of fire or explosion.

5.2 Laser classification

The tool conforms to Laser Class 2 based on the
IEC60825-1 / EN60825-01:2007 standard and Class
II based on CFR 21 § 1040 (FDA). The eyelid closure
reflex protects the eyes when a person looks into the
beam unintentionally for a brief moment. This eyelid
closure reflex, however, may be negatively affected
by medicines, alcohol or drugs. This tool may be
used without need for further protective measures.
Nevertheless, as with the sun, one should not look
directly into sources of bright light. Do not direct the
laser beam toward persons.

5.3 Proper organization of the work area

a) Secure the area in which you are working and
take care to avoid directing the beam toward
other persons or toward yourself when setting up
the tool.
b) Take care to ensure that the tool is set up correctly
on the PTA 70 tripod adapter.
c) Use the tool only within its specified limits.

5.4 Electromagnetic compatibility

Although the tool complies with the strict requirements
of the applicable directives, Hilti cannot entirely rule out
the possibility of the tool being subject to interference
caused by powerful electromagnetic radiation, leading
to incorrect operation. Check the accuracy of the tool
by taking measurements by other means when working
under such conditions or if you are unsure. Likewise, Hilti
cannot rule out the possibility of interference with other
devices (e.g. aircraft navigation equipment).
2. Plug the supply cord into the power outlet.
