5.3 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 or from panes of glass
or through other objects may be inaccurate.
c) Use the tool only within its specified limits.
5.4 Electromagnetic compatibility
Although the appliance complies with the strict require-
ments of the applicable directives, Hilti cannot entirely
rule out the possibility of interference to the appliance
caused by powerful electromagnetic radiation, leading to
incorrect operation. Check the accuracy of the appliance
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).
5.5 Magnetic holder
CAUTION! Although the magnetic holder is equipped
with powerful magnets, the load it is capable of carrying
is limited to 1.1 kg (2.5 lbs).
To prevent injury, take care to avoid trapping your fingers
between the magnets and the mounting surface when
bringing the magnetic holder into place.
1. Pull the cover to the side so that the charging cord
socket becomes accessible.
2. Connect the charging cord from the AC adapter or
car charging connector to the battery.
NOTE The charging status is shown by the battery
display on the tool while charging is taking place.
6.4 Setting up
Set up the rotating laser at a suitable, secure location,
taking care to ensure that there are no objects interrupting
the field of view between the rotating laser and the
machine receiver. The Hilti PRM 15 machine receiver can
be used at a radius of up to 488 m (750 ft.) (this range
also depends on the power of the rotating laser used).
WARNING
Observe all safety information given in the PRM 15 oper-
ating instructions and observe all other safety instructions
and precautions applicable to the area in which you are
working.
6.5 Repositioning the magnets
