▶ Observe the national health and safety requirements.
2.2 Proper preparation of the working area
▶ Avoid awkward body positions when working from ladders. Make sure you work from a safe stance and
stay in balance at all times.
▶ Secure the site in which you are taking measurements and take care to avoid directing the beam towards
other persons or towards yourself when setting up the tool.
▶ Measurements taken through panes of glass or other objects may be inaccurate.
▶ Ensure that the tool is set up on a stable, level surface (not subject to vibration).
▶ Use the tool only within its specified limits.
▶ If several laser tools are used in the same working area, care must be taken to avoid confusing the
beams.
▶ Strong magnetic fields may affect the accuracy of the tool. Magnetic objects should thus be kept away
from the measuring tool. Hilti magnetic adapters may be used.
▶ When the tool is brought into a warm environment from very cold conditions, or vice-versa, allow it to
become acclimatized before use.
2.3 Electromagnetic compatibility
Although the device complies with the strict requirements of the applicable directives, Hilti cannot entirely
rule out the possibility of interference to the device caused by powerful electromagnetic radiation, possibly
leading to incorrect operation. Check the accuracy of the device 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).
2.4 Laser classification for laser class 2/class II tools
The tool complies with laser Class 2 as per IEC 60825-1:2007 / EN 60825-1:2008 and Class II as per
CFR 21 § 1040 (FDA). These devices can be used without further protective measures. Nevertheless, as with
the sun, do not look directly into the light source. If you do inadvertently look into the laser beam, immediately
close your eyes and move your head clear of the laser beam. Do not aim the laser beam at persons.
2.5 Careful handling and use of batteries
▶ Observe the special guidelines applicable to the transport, storage and use of lithium-ion batteries.
▶ Do not expose batteries to high temperatures, direct sunlight or fire.
▶ Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C
(176 °F).
▶ Do not use or charge batteries that have suffered mechanical impact, have been dropped from a height
or show signs of damage. In this case, always contact your Hilti Service.
▶ If the battery is too hot to touch it may be defective. Put the battery in a place where it is clearly visible
and where there is no risk of fire, at an adequate distance from flammable materials. Allow the battery to
cool down. If it is still too hot to touch after an hour, the battery is faulty. Contact Hilti Service.
