# Safety Instructions for Rotary Lasers and Remote Control

All instructions must be read and observed in order to enable work to be carried out safely. The integrated safeguards may be compromised if these instructions are not observed. Never make warning signs unrecognisable. STORE THESE INSTRUCTIONS IN A SAFE PLACE AND INCLUDE THEM WITH THE PRODUCT WHEN GIVING IT TO A THIRD PARTY.

- Warning! If operating or adjustment devices other than those specified here are used or other procedures are carried out, this can lead to dangerous exposure to radiation.

- The measuring tool is delivered with a laser warning sign (marked in the illustration of the measuring tool on the graphics page).

- If the text of the laser warning label is not in your national language, stick the provided warning label in your national language over it before operating for the first time.

- Do not make any modifications to the laser equipment.

- Do not use the laser goggles (accessory) as protective goggles. The laser goggles make the laser beam easier to see; they do not protect you against laser radiation.

- Do not use the laser goggles (accessory) as sunglasses or while driving. The laser goggles do not provide full UV protection and impair your ability to see colours.

- Have your product serviced only by a qualified specialist using only original replacement parts. This will ensure that the safety of the product is maintained.

- Do not let children use the laser measuring tool unsupervised. They could unintentionally blind themselves or other persons.

- Do not operate in potentially explosive atmospheres, such as in the presence of flammable liquids, gases or dusts. Sparks may be produced, which can ignite dust or fumes.

Additional Safety Instructions for GRL 250 HV :

| Do not direct the laser beam at persons or animals and do not stare into the direct or reflected laser beam yourself. You could blind somebody, cause accidents or damage your eyes.

- If laser radiation hits your eye, you must close your eyes and immediately turn your head away from the beam.

Additional Safety Instructions for GRL 300 HV, GRL 300 HVG :

- The laser exit holes on the measuring tool are marked with warning labels. Take note of their position when using the measuring tool.

- If the text of these labels is not in your national language, stick the provided warning label in your national language over it before operating for the first time.

- Comply with any applicable national regulations when using a laser from laser class 3R. Failure to comply with these regulations may cause injuries.

- The measuring tool should only be operated by people who have experience in using laser tools. According to EN 60825-1, this includes knowledge of the biological impact of the laser on eyes and skin as well as the correct application of laser safety guidelines to prevent hazards.

- Mark out the area where the measuring tool is being used with suitable laser warning signs. This will prevent people who are not using the measuring tool from entering the danger zone.

- Do not store the measuring tool in places which can be accessed by unauthorised individuals. People who are unfamiliar with the operation of the measuring tool may cause harm to themselves or others.

| Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself. This measuring tool generates laser class 3R laser radiation according to EN 60825‑1. Looking into the laser beam directly can cause eye injuries – even from far away.

- Ensure that the laser radiation area is guarded or screened. Restricting the laser radiation to controlled areas prevents eye injuries being caused to people who are not using the laser measuring tool.

- Always position the measuring tool such that the laser beams travel far above or below eye level. This ensures that no eye injuries are caused.

- Avoid laser beam reflections on smooth surfaces such as windows or mirrors. Even the reflected laser beam can cause eye injuries.
