Hilti PR 2-HS A12 Manual De Instrucciones Original página 9

▶ You must check the accuracy of the tool after it has been dropped or subjected to other mechanical
stresses.
▶ When the tool is brought into a warm environment from very cold conditions, or vice-versa, allow
it to become acclimatized before use.
▶ Make sure that the tool is mounted securely when adapters or accessories are used.
▶ Keep the laser exit aperture clean to avoid measurement errors.
▶ Although the tool is designed for the tough conditions of jobsite use, as with other optical and
electronic instruments (e.g. binoculars, spectacles, cameras) it should be treated with care.
▶ 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.
▶ Check the tool before using it for important measuring work.
▶ Check the accuracy of the measurements several times during use of the tool.
▶ Ensure that the workplace is well lit.
▶ Do not expose the laser to rain or wet conditions.
▶ Avoid touching the contacts.
▶ Maintain the tool carefully. Check for misalignment or binding of moving parts, breakage of parts
and any other condition that may affect the tool's operation. Have damaged parts repaired before
using the tool. Many accidents are caused by poorly maintained tools.
2.1.3 Proper preparation of the working area
▶ Secure the area in which you will be taking measurements. Make sure that the laser beam is not
directed toward other persons or toward yourself while setting up the PR 2-HS A12.
▶ Avoid unfavorable body positions when working from ladders. Make sure you work from a safe
stance and stay in balance at all times.
▶ Readings taken in the vicinity of reflective objects or surfaces, through panes of glass or similar materials
may produce incorrect results.
▶ Ensure that the tool is set up on a stable, level surface (not subject to vibration).
▶ Use the tool only within its specified limits.
▶ Use the tool and its accessories etc. in accordance with these instructions and in the manner
intended for the particular type of tool. Take the working conditions and the task to be performed
into account. Use of tools for applications different from those intended could result in a hazardous
situation.
▶ Use of the telescopic staff in the vicinity of overhead high voltage cables is not permissible.
2.1.4 Electromagnetic compatibility
Although the tool complies with the strict requirements of the applicable directives, Hilti cannot exclude the
following possibilities:
• The tool may be negatively affected by powerful electromagnetic radiation, possibly leading to incorrect
operation.
In these cases, or if you are otherwise unsure, confirmatory measurements should be made by other
means.
• The tool may cause interference to other devices (e.g. aircraft navigation equipment).
Only for Korea:
This device is suitable for the electromagnetic radiation encountered in residential environments (Class B). It
is intended mainly for use in residential environments but may also be used in other environments.
2.1.5 Laser classification for Class 2 laser products
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.
CAUTION
Risk of injury! Do not direct the laser beam toward persons.
▶ Never look directly into the source of the laser beam. In the event of direct eye contact, close your eyes
and move your head out of the path of the laser beam.
2.1.6 Careful use of battery-powered tools
▶ Do not expose batteries to high temperatures, the direct heat of the sun, and keep them away
from fire. There is a risk of explosion.
