  • The working range increases depending on how well the laser light is reflected from the surface of the target (scattered, not reflective) and the increased brightness of the laser point to the ambient light intensity (interior spaces, twilight). In unfavourable conditions, e.g., with extreme interior illumination or a badly reflecting surface, the measuring range may be limited.
  • In unfavourable conditions, e.g., with extreme interior illumination, badly reflecting surface or the room temperature deviating heavily from 25 °C, the maximum deviation can be up to ±7 mm per 15 m. In favourable conditions, a deviation influence of ±0.05 mm/m must be taken into account. The measuring tool can be clearly identified with the serial number 6 on the type plate.


Inserting/Replacing the Batteries
Alkali-manganese batteries are recommended for the measuring tool. To open the battery lid 4, press the latch 5 in the direction of the arrow and remove the battery lid. Insert the batteries. When inserting, pay at-tention to the correct polarity according to the representation on the inside of the battery compartment. When the battery symbol appears for the first time on the display, measurements are still possible for approx. 15 minutes. When the battery symbol flashes, the batteries must be replaced; measurements are no longer possible. Replace all batteries at the same time. Only use same-brand batteries with identical battery capacity.

  • Remove the batteries from the measuring tool when not using it for extended periods. When storing for extended periods, the batteries can corrode and discharge themselves


Initial Operation

  • Do not leave the switched on measuring tool unattended and switch the measuring tool off after use. Other persons could be blinded by the laser beam.
  • Protect the measuring tool against moisture and direct sunlight.
  • Do not subject the measuring tool to extreme temperatures or variations in temperature. As an example, do not leave it in vehicles for a long time. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into op-eration. In case of extreme temperatures or variations in temperature, the accuracy of the measuring tool can be impaired.
  • Avoid heavy impact to or falling down of the measuring tool. After severe exterior effects to the measuring tool, it is recommended to carry out a check (see “Checking the Measuring Tool”, page 21) each time before continuing to work.

Switching On and Off
To switch on the measuring tool, push the On/Off switch 1 toward the rear. When switching on the measuring tool, the laser beam is switched on. The LASER indicator flashes on the display.
To switch off the measuring tool, push the On/Off switch 1 toward the front.

Measuring Procedure
After the measuring tool is switched on, continuous measurement takes place. Aim the laser beam at the target surface. The current measuring value g is displayed in the bottom line of the display (see figure A). During continuous measurement, the measuring tool can be moved relative to the target, whereby the current measuring value g is updated approx. every 0.5 seconds in the bottom line of the display (see figure B). In this manner, as an example, you can move a certain distance away from a wall, while the actual distance can always be read. The LASER indicator flashes on the display. The rear edge of the measuring tool is preset as the reference plane for the measurement. For a wall to wall measurement, as an example, position the measuring tool with its rear edge against the initial wall.

  • Do not point the laser beam at persons or animals and do not look into the laser beam yourself, not even from a large distance.

“HOLD” Function

Press the “HOLD” button 2 to stop the measuring procedure. The laser beam is switched off and the HOLD indication appears on the display. The current measuring value is still displayed in the bottom line of the display but is no longer continuously updated. Press the “HOLD” button 2 once more to switch the laser on again. The LASER indicator flashes on the display. The previous measuring value is displayed in the top line. The continuously updated/current measuring value is displayed in the bottom line. Press the “HOLD” button 2 once more to stop the measuring procedure again. The laser beam is switched off and the HOLD indication appears on the display. The previous measuring value is displayed in the top line. The current measuring value is displayed in the bottom line but is no longer continuously updated. When no button on the measuring tool is pressed for approx. 5 minutes, the measuring tool automatically switches off to save the batteries. When a measuring value was held using the “HOLD” function, it is retained after the automatic shut-off. After switching the measuring tool on again by pressing the “HOLD” button 2, the previous measuring value e is indicated in the top line of the display.

Working Advice

General Information
The reception lens 8 and the laser beam outlet 9 must not be covered when taking a measurement. Measurement takes place at the centre of the laser beam, even when tar-get surfaces are sighted at an incline.

Influence Effects on the Measuring Range
The measuring range depends on the light conditions and the reflection properties of the target surface.

Influence Effects on the Measuring Result
Due to physical effects, faulty measurements cannot be excluded when measuring on different surfaces. Included here are:

  • Transparent surfaces (e.g., glass, water),
  • Reflecting surfaces (e.g., polished metal, glass),
  • Porous surfaces (e.g. insulation materials),
  • Structured surfaces (e.g., roughcast, natural stone).

Also, air layers with varying temperatures or indirectly received reflections can affect the measured value.
Troubleshooting – Causes and Corrective Measures

The measuring tool monitors the proper function for each measurement. When a defect is detected, all indicators on the display flash. In this case, or when the corrective measures listed above cannot correct the error, have your dealer forward the measuring tool to an authorised Bosch after-sales service.

Checking the Measuring Tool
The accuracy of the measuring tool can be checked as follows:– Select a permanently unchangeable measuring section with a length of approx. 3 to 10 metres; its length must be precisely known (e.g. the width of a room or a door opening). The measurement should be carried out under favourable conditions, meaning, the measuring distance must be indoors and the target surface for the measurement must be smooth and reflect well. Measure the distance 10 times after another. Under favourable conditions, the deviation of the individual measurements from the mean value must not exceed ±3.5 mm (max.) over the complete measuring distance. Log the measurements, so that you can compare their accuracy at a later point of time.

Maintenance and Service

Maintenance and Cleaning
Keep the measuring tool clean at all times. Do not immerse the measuring tool in water or other fluids. Wipe off debris using a moist and soft cloth. Do not use any cleaning agents or solvents. Maintain the reception lens 8 in particular, with the same care as required for eye glasses or the lens of a camera. If the measuring tool should fail despite the care taken in manufacturing and testing procedures, repair should be carried out by an authorised af-ter-sales service centre for Bosch power tools. Do not open the measuring tool yourself. For repairs, send in the measuring tool in.
