Hilti PM 20-CG Manual De Instrucciones Original página 29

▶ Do not operate the product in explosive atmospheres, such as in the presence of flammable
liquids, gases or dust.
▶ Keep children and other persons clear when the product is in use.
▶ Use the product only within its specified limits.
▶ Comply with your national accident prevention regulations.
Electrical safety
▶ Do not expose the product to rain or moisture. Penetrating moisture can cause short circuits, electrical
shock, burns or explosions.
▶ Although the product is protected against the entry of moisture, it should be wiped dry before
being put away in its transport container.
Personal safety
▶ Stay alert, watch what you are doing and use common sense when operating a measuring tool. Do
not use a measuring tool while you are tired or under the influence of drugs, alcohol or medication.
A moment of inattention while operating the measuring tool can result in serious personal injury.
▶ Avoid unusual body positions. Keep proper footing and balance at all times.
▶ Wear personal protective equipment. Wearing personal protective equipment reduces the risk of injury.
▶ Do not render safety devices ineffective and do not remove information and warning notices.
▶ Avoid accidental starting. Make sure that the measuring tool is switched off before connecting it
to the battery and before picking it up or carrying it.
▶ Use the product and accessories in accordance with these instructions and in the way specified for
this special type of tool. Take the working conditions and the work to be performed into account.
Use of products for applications different from those intended could result in hazardous situations.
▶ Do not lull yourself into a false sense of security and do not flout the safety rules for measuring
tools, even if you are familiar with the measuring tool after using it many times. Carelessness can
result in serious injury within a fraction of a second.
▶ Do not use the measuring tool in the vicinity of medical devices.
Using and handling the measuring tool
▶ Use the product and accessories only when they are in perfect working order.
▶ Store measuring tools out of reach of children when not in use. Do not allow persons who are not
familiar with the product or these instructions to operate it. Measuring tools are dangerous in the
hands of inexperienced persons.
▶ Measuring tools need care and attention. Check that moving parts operate satisfactorily and do
not jam, and make sure that no parts are broken or damaged in such a way that the measuring
tool might no longer function correctly. Have damaged parts repaired before using the measuring
tool. Many accidents are caused by poorly maintained measuring tools.
▶ Do not under any circumstances modify or tamper with the product. Changes or modifications not
expressly approved by Hilti may restrict the user's authorization to operate the product.
▶ Check the accuracy of the measuring tool before using it for important measurements, and if it
has been dropped or subjected to other mechanical stresses.
▶ Due to the measuring principle employed, the results of measurements can be negatively affected
by certain ambient conditions. These include, for example, the proximity of devices that produce
strong magnetic or electro-magnetic fields, vibrations and temperature changes.
▶ Rapidly changing measuring conditions can falsify the results.
▶ When the product is brought into a warm environment from very cold conditions, or vice-versa,
allow it to become acclimatized before use. Big differences in temperature can lead to incorrect
operation and incorrect results.
▶ When adapters or accessories are used, make sure they are mounted securely.
▶ The measuring tool is designed for the tough conditions of jobsite use, but as with other optical
and electrical products (e.g. binoculars, spectacles, cameras) it must be handled with care.
▶ The specified operating and storage temperatures must be observed.
2.2 Additional safety instructions for laser measuring tools
▶ Laser radiation in excess of Class 2 can be emitted if the product is opened without correct
procedure being followed. Have the product repaired only by Hilti Service.
▶ Secure the area in which you will be taking measurements. While setting up the product, make
sure that you do not direct the laser beam toward yourself or others. Laser beams should be
projected well above or well below eye height.
▶ Keep the laser exit window clean in order to avoid measurement errors.
