4 Safety instructions

4.1 Basic information concerning safety
In addition to the information relevant to safety given
in each of the sections of these operating instructions,
the following points must be strictly observed at all
times.
4.2 General safety rules
a) Keep other persons, especially children, away
from the area in which the work is being carried
out.
b) Check the condition of the tool before use. If the
tool is found to be damaged, have it repaired at a
Hilti service center.
c) Do not render safety devices ineffective and do
not remove information and warning notices.
d) The tool must be checked at a Hilti service center
after it has been dropped or subjected to other
mechanical stresses.
e) To avoid measurement errors, the receiving area
must be kept clean.
Although the tool is designed for the tough condi-
f)
tions of jobsite use, as with other optical and elec-
tronic instruments (e.g. binoculars, spectacles,
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) To avoid hearing damage, hold the tool as far
away as possible from your ear (and other per-
sons' ears).

5 Before use

5.1 Inserting the batteries 1
CAUTION
Do not use damaged batteries.
4.2.1 Electrical
a) Keep the batteries out of reach of children.
b) Do not allow the batteries to overheat and do not
expose them to fire. The batteries may explode or
release toxic substances.
c) Do not charge the batteries.
d) Do not solder the batteries into the tool.
e) Do not discharge the batteries by short circuiting
as this may cause them to overheat and swell up.
f) Do not attempt to open the batteries and do not
subject them to excessive mechanical stress.
4.3 Proper organization of the work area
a) 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.
b) Measurements taken through panes of glass or other
objects may be inaccurate.
c) Use the tool only within its specified limits.

4.4 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).
DANGER
Do not mix old and new batteries. Do not mix batteries
of different makes or types.
1. Remove the batteries from the package and insert
them in the tool (9).
NOTE Only batteries recommended by Hilti may be
used to power the tool.
2. Check that the battery terminals are positioned cor-
rectly as shown on the underside of each unit.
