# 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 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.

- Do not make any modifications to the laser equipment. The setting options described in these operating instructions can be used safely.

- 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.

- Protect the measuring tool and remote control from moisture and direct sunlight as well as from extreme temperatures or fluctuations in temperature. For example, do not leave them in a car for extended periods of time. In case of large variations in temperature, allow the measuring tool and the remote control to adjust to the ambient temperature before putting them into operation. Before continuing work with the measuring tool, always perform an accuracy check see Accuracy Check and Calibration of the Measuring Tool.

- Never leave the measuring tool unattended when switched on, and ensure the measuring tool is switched off after use. Others may be blinded by the laser beam.

- Avoid substantial knocks to the measuring tool and avoid dropping it. Always carry out an accuracy check before continuing work if the measuring tool has been subjected to severe external influences see Accuracy Check and Calibration of the Measuring Tool.

- Do not use any optical instruments such as binoculars or magnifying glasses to view the radiation source. Doing so can damage your eyes.

- Do not modify or open the rechargeable battery or the battery. There is a risk of short-circuiting.

- In case of damage and improper use of the battery, vapours may be emitted. The battery can set alight or explode. Ensure the area is well ventilated and seek medical attention should you experience any adverse effects. The vapours may irritate the respiratory system.

- If used incorrectly or if the battery is damaged, flammable liquid may be ejected from the battery. Contact with this liquid should be avoided. If contact accidentally occurs, rinse off with water. If the liquid comes into contact with your eyes, seek additional medical attention. Liquid ejected from the battery may cause irritation or burns.

- The battery can be damaged by pointed objects such as nails or screwdrivers or by force applied externally. An internal short circuit may occur, causing the battery to burn, smoke, explode or overheat.

- When the battery is not in use, keep it away from paper clips, coins, keys, nails, screws or other small metal objects that could make a connection from one terminal to another. A short circuit between the battery terminals may cause burns or a fire.

- Only use the Bosch rechargeable battery with products from the manufacturer. This is the only way in which you can protect the battery against dangerous overload.

- Only charge the batteries using chargers recommended by the manufacturer. A charger that is suitable for one type of battery may pose a fire risk when used with a different battery.

| Protect the rechargeable batteries against heat, e.g. against continuous sunlight, fire, dirt, water, and moisture. There is a risk of explosion and short circuit.

| Keep the magnetic accessories away from implants and other medical devices, e.g. pacemakers or insulin pumps. The magnets in the accessories generate a field that can impair the function of implants and medical devices.

- Keep the magnetic accessories away from magnetic data‌ storage media and magnetically-sensitive devices. The effect of the magnets in the accessories can lead to irreversible data loss.

- The measuring tool is equipped with a wireless interface. Local operating restrictions, e.g. in aeroplanes or hospitals, must be observed.

- Caution! When using the measuring tool with Bluetooth®, a fault may occur in other devices and systems, aeroplanes and medical devices (e.g. pacemakers, hearing aids). Also, damage to people and animals in the immediate vicinity cannot be completely excluded. Do not use the measuring tool with Bluetooth® in the vicinity of medical devices, petrol stations, chemical plants, areas with a potentially explosive atmosphere and in blasting areas. Do not use the measuring tool with Bluetooth® on aeroplanes. Avoid using the product near your body for extended periods.
