Hilti PR 300-HV2S, Operating Instructions Manual

Page: 12 / 31

2.3 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
from ladders. Make sure you work from a safe
stance and stay in balance at all times.
c) Readings taken in the vicinity of reflective objects or
surfaces, through panes of glass or similar materials
may produce incorrect results.
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) Make sure that your PR 300-HV2S is responding only
to your PRA 300 and not to any other PRA 300 that
may be in use on the jobsite.
g) When working in “charging during operation”
mode, attach the AC adapter in a secure posi-
tion, e.g. on a tripod.
h) Use of products for applications different from those
intended could result in hazardous situations. Use
the product and its accessories etc. in accor-
dance with these instructions and in the manner
intended for the particular type of product. Take
the working conditions and the work to be per-
formed into account.
i) Use of the telescopic staff in the vicinity of over-
head high voltage cables is not permissible.
2.3.1 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).
2.3.2 Laser classification for Laser Class 2
products
According to the version purchased, the tool complies
with Laser Class 2 as per IEC60825-1:2007 / EN60825-
1:2007. 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. In the
event of direct eye contact with the laser beam, close
your eyes and move your head out of the path of the laser
beam. Do not direct the laser beam toward persons.
3 Description
3.1 Use of the product as directed
The Hilti PR 300-HV2S is a rotating laser tool with a visible rotating laser beam and a reference beam set at 90° to the
main beam. The rotating laser can be used vertically, horizontally and for inclinations in one or two planes.
The tool is designed to be used to determine, transfer and check levels, verticals, slopes and right angles. Examples of
its uses are: transferring datums and height marks, determining right angles for walls, vertical alignment on reference
points and setting out slopes.
The tool is designed for professional use and may be operated, serviced and maintained only by trained, authorized
personnel. This personnel must be informed of any special hazards that may be encountered. The tool and its ancillary
equipment may present hazards when used incorrectly by untrained personnel or when used not as directed.
Hilti supplies various accessories which allow the tool to be used with maximum efficiency.
To avoid the risk of injury, use only genuine Hilti accessories and insert tools.
3.2 Features
The tool makes it possible for a single person to level or align in any plane quickly and with great accuracy.
Leveling takes place automatically after the tool is switched on. The laser beam is activated after the tool has leveled
itself.
LEDs indicate the current operating status.
The tool is powered by a rechargeable Li‑ion battery which can be charged while the tool is in operation.
3.3 Combined use of the PRA 300 remote control / laser receiver
The PRA 300 is a combined remote control unit and laser receiver. It can be used to control the PR 300-HV2S rotating
laser over great distances. The PRA 300 also serves as a laser receiver and can thus be used to detect and indicate
the laser beam at great distance.
3.4 Digital distance measurement display
The laser receiver displays digitally the distance between the laser plane and the marking notch. This allows the user to
determine the exact position of the receiver relative to the laser plane, with millimeter accuracy, in a single operation.
