Q: Why is the laser not visible on my BOSCH Atino laser level?

If the laser of your BOSCH Atino is not visible, here are the checks to perform in order: 1. Check that the device is turned on and level Briefly press the On/Off button. The light ring should flash three times in green (sufficient battery). The laser line is only displayed if the device is tilted a maximum of 10° forward or backward . The light ring indicates the status: red = not level , yellow = almost level, green = perfectly level. Adjust the position until the green ring is achieved. 2. Check the battery status If the light ring flashes three times in yellow at startup, the battery is weak. The device uses 1 LR6 (AA) 1.5 V battery. Replace it with a new alkaline battery (lithium-ion batteries may damage the device). A weak battery can prevent the laser from displaying. 3. Check the operating temperature The device operates only between +5°C and +40°C . If the temperature is outside this range, allow the device to reach the required ambient temperature before reusing it. 4. Clean the laser lens Dirt and dust can block the laser. Regularly clean the laser output surface with a soft, dry cloth. 5. Recalibrate the device After a fall or severe shock, the laser may require recalibration. Hold the On/Off button until the laser flashes, then rotate the device more than 360° for at least 15 seconds. If the laser remains invisible after all these checks, contact BOSCH customer service, the device may have a technical defect.

Q: What does the battery symbol with a triangle displayed on the BOSCH Zamo screen mean?

The battery symbol with a triangle is the battery level alert that appears on your BOSCH Zamo screen when the batteries begin to weaken. Action timeline: At the first appearance of the symbol - you can still use the device for about 15 minutes When the symbol starts to blink - you need to replace the batteries immediately. You can no longer take measurements. How to properly replace the batteries: Use manganese alkaline batteries (do not use lithium-ion batteries) Always replace all batteries at the same time Only use batteries of the same brand and capacity Observe the polarity indicated in the compartment Once the batteries are replaced correctly, the alert symbol will disappear and you can resume your measurements (typical battery life in measurement mode: about 5 hours).

Q: Why does the laser of the BOSCH PLL 360 turn off automatically after a certain period of inactivity?

According to the manual of the BOSCH PLL 360 , this device has no programmed automatic shut-off function . The laser should remain on as long as the On/Off switch is held in the "On" position. If your device turns off by itself after a certain period of inactivity, this indicates a malfunction. Check the following points: Battery status: The PLL 360 requires 4 LR6 or HR6 (AA) batteries of 1.5 V or 1.2 V. A weak battery can cause unexpected shut-offs. Replace all four batteries simultaneously, ensuring the polarities are respected in compartment 5. Faulty switch: Check that the On/Off switch 2 is not damaged or partially pressed. Try to manipulate it gently. Electronic defect: If the problem persists after replacing the batteries, your device likely has an internal malfunction requiring intervention from BOSCH customer service. Tip: For prolonged storage, remove the batteries to prevent corrosion, which could also cause this type of problem.
