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 towards
other persons or towards yourself when setting
up the tool.
b) Avoid unfavorable body positions when working
on ladders or scaffolding. Make sure you work
from a safe stance and stay in balance at all
times.
c) Measurements taken through or from panes of
glass or through other objects may be inaccurate.
d) Ensure that the tool is set up on a steady, level
surface (not subject to vibration).
e) Use the tool only within its specified limits.
f) When working in “charging during operation”
mode, attach the mains adapter in a secure
position, e.g. on a tripod.
g) Use the appliance and its accessories etc. in ac-
cordance with these instructions and in the man-
ner intended for the particular type of appliance.
Take the working conditions and the work to be
performed into account. Use of appliances for
applications different from those intended could
result in a hazardous situation.
h) Use of the telescopic staff in the vicinity of
overhead high voltage cables is not permissible.
5.3.1 Electromagnetic compatibility
Although the tool complies with the strict require-
ments of the applicable directives, Hilti cannot en-
tirely 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 pos-
sibility of interference with other devices (e.g. aircraft
navigation equipment).
5.3.2 Laser classification for laser class II
appliances
Depending on the version purchased, the tool com-
plies with Laser Class 2 in accordance with IEC825-
3:2007 / EN60825-3:2007 and Class II in accordance
with CFR 21 § 1040 (FDA). This tool may be used
without need for further protective measures. The
eyelid closure reflex protects the eyes when a per-
son looks into the beam unintentionally for a brief
moment. This eyelid closure reflex, however, may be
negatively affected by medicines, alcohol or drugs.
Nevertheless, as with the sun, one should not look
directly into sources of bright light. Do not direct the
laser beam toward persons.
5.4 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 user must check the accuracy of the tool
after it has been dropped or subjected to other
mechanical stresses.
c) When the tool is brought into a warm environ-
ment from very cold conditions, or vice-versa,
allow it to become acclimatized before use.
d) If mounting on an adapter, check that the tool is
screwed on securely.
e) Keep the laser exit aperture clean to avoid meas-
urement errors.
f) Although the tool is designed for the tough con-
ditions of jobsite use, as with other optical and
electronic instruments (e.g. binoculars, spec-
tacles, cameras) it should be treated with care.
g) Although the tool is protected to prevent entry
of dampness, it should be wiped dry each time
before being put away in its transport container.
h) Check the tool before using it for important meas-
uring work.
i) Check the accuracy of the measurements several
times during use of the tool.
j) Use the mains adapter only for connecting to the
mains supply.
k) Check to ensure that the tool and mains adapter
do not present an obstacle that could lead to a
risk of tripping and personal injury.
l) Ensure that the workplace is well lit.
m)Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
n) Check the condition of the extension cord and
replace it if damage is found. Do not touch the
mains adapter if the extension cord or mains
adapter are damaged while working. Disconnect
the supply cord plug from the power outlet.
Damaged supply cords or extension cords present
a risk of electric shock.
