• A) The working range increases depending on how well the laser light is reflected from the surface of the target (scattered, not reflective) and with the increased brightness of the laser point to the ambient light intensity (interior spaces, twilight). In unfavorable conditions (e.g. when measuring outdoors in intense sunlight), it may be necessary to use the target plate.
  B) In unfavorable conditions (e.g. at intense sunlight or an insufficiently reflecting surface), the maximum deviation is ±7mm per 25 m. In favorable conditions, a deviation influence of ±0.05 mm/m must be taken into account.
  C) In the continuous measurement function, the maximum operating temperature is +40 °C.
  D) Fewer measurements are possible when using 1.2 V rechargeable batteries than with 1.5 V batteries. Please observe the article number on the type plate of your measuring tool. The trade names of the individual measuring tools may vary. The measuring tool can be clearly identified with serial number 18 on the type plate.

Assembly

Inserting/Replacing the Battery
Using alkali-manganese or rechargeable batteries is recommended for the operation of the measuring tool. Less measurements are possible when using 1.2 V rechargeable batteries than with 1.5 V batteries. To open the battery lid 15, press the latch 14 in the direction of the arrow and remove the battery lid. Insert the batteries/rechargeable batteries. When inserting, pay attention 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, at least 100 measurements are still possible. When the battery symbol flashes, the batteries/ rechargeable batteries must be replaced; measurements are no longer possible. Always replace all batteries/rechargeable batteries at the same time. Do not use different brands or types of batteries/rechargeable batteries together.

• Remove the batteries/rechargeable batteries from the measuring tool when not using it for longer periods. When stored for longer periods, the batteries/rechargeable batteries can corrode and discharge themselves.

Operation

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 sun light.
• Do not subject the measuring tool to extreme temperatures or variations in temperature. As an example, do not leave it in vehicles for longer periods. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. 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 an accuracy check (see “Accuracy Check of the Measuring Tool”, page 22) each time before continuing to work.

Switching On and Off
To switch on the measuring tool, briefly press the On/Off button 1 or measuring button 9. When switching on the measuring tool, the laser beam is not switched on yet. To switch off the measuring tool, press the On/Off button 1 for a few seconds. If none of the measuring tool buttons are pressed for approx. 5minutes, the measuring tool switches off automatically in order to extend the service life of the battery. When a measured value has been stored, it is retained in automatic switch-off mode. When switching on the measuring tool again, “M” is indicated in the display.
Measuring Procedure
After switching on, the measuring tool is in the length measurement mode. Other measuring modes can be switched to by pressing the respective function/mode button (see “Measuring Functions”, page 18). After switching on, the rear edge of the measuring tool is preset as the reference level for the measurement. To change the reference level, see “Selecting the Reference Level”, page 18. Upon selection of the measuring function and the reference level, all further steps are carried out by pushing the measuring button 9. With the reference level selected, place the measuring tool against the desired measuring line (e.g. a wall). Push the measuring button 9 to switch on the laser beam.

• 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. Aim the laser beam at the target surface. Push the measuring button 9 again to initiate the measurement. In the tracking function, the measurement already starts upon first actuation of the measuring button 9. Typically, the measured value appears after 0.5 and latest after 4 seconds. The duration of the measurement depends on the distance, the light conditions and the reflection properties of the target surface. The end of the measurement is indicatedby a signal tone. The laser beam is switched off automatically upon completion of the measurement. When no measurement has taken place approx. 20 seconds after sighting, the laser beam is switched off automatically to save the batteries.

Selecting the Reference Level (see figures A–B)
Two different reference levels are available for measuring:

• The rear edge of the measuring tool (e.g. when placed against a wall),
• The front measuring-tool edge (e.g. when measuring onward from a table edge).

To change the reference level, press button 2 until the requested reference level is indicated on the display. Each time after switching on the measuring tool, the rear end of the measuring tool is preset as the reference level.

Measuring Functions

Length Measurement
For length measurement, push button 6. The indicator for length measurement appears in the display.

Push the measuring button 9 once for sighting and once more to take the measurement. The measured value is indicated at the bottom in the display.

Area Measurement
For area measurements, push button 5. The indicator for area measurement appears in the display  Afterward, measure the length and the width, one after another, in the same manner as a length measurement. The laser beam remains switched on between both measurements.
After taking the second measurement, the area/surface is automatically calculated and displayed. The last individual measured value is indicated at the bottom in the display, while the final result is shown at the top.

Volume Measurement
For volume measurements, push button 10. The indicator for volume measurement appears in the display Afterwards, measure the length, width and height, one after another, in the same manner as for a length measurement. The laser beam remains switched on
between all three measurements. After taking the third measurement, the volume is automatically calculated and displayed. The last individual measured value is indicated at the bottom in the display, while the final result is shown at the top.

Continuous Measurement (Tracking) (see figure C)
For continuous measurements, the measuring tool can be moved relative to the target, whereby the measuring value is updated approx. every 0.5 seconds. In this manner, as an example, you can move a certain distance away from a wall, while the actual distance can always be read. For continuous measurements, push button 12. The indicator for continuous measurement (tracking) appears in the display
Press the measuring button 9 to initiate the measuring procedure. Move the measuring tool until the required distance value is indicated at the bottom of the display. Pushing the measuring button 9 interrupts the continuous measurement. The current measured value is indicated in the display. Repeated pushing of the measuring button 9 starts the continuous measuring again. The continuous measurement automatically switches off after 5 minutes. The last measured value remains indicated on the display. The continuous measuring can also be ended by pushing the buttons 6, 5 or 10 which changes the measuring function.

Deleting Measured Values
Briefly pressing button 1 deletes the last individual measuring value determined in all measuring functions. Briefly pressing the button repeatedly deletes the individual measured values in reverse order.
Memory Functions
When switching off the measuring tool, the value in the memory is retained.
Storing/Adding Measured Values

Push the memory add button 4 in order to store the current measured value – a length, area or volume value, depending on the current measuring function. As soon as a value has been stored, “M” is indicated in the display and the “+” behind it briefly flashes. If a value is already stored in the memory, the new value is added to the memory contents, however, only when the measures of unit correspond. As an example, when an area value is in the memory and the current measured value is a volume value, the addition cannot take place. “Error” briefly flashes in the display.
Subtracting Measured Values
Push the memory subtraction button 3 in order to subtract the current measured value from the memory value. As soon as a value has been subtracted, “M” is indicated in the display and the “–” behind it briefly flashes. If a value is already stored in the memory, the new measured value can be subtracted only when the measures of unit correspond (see “Storing/Adding Measured Values”).
Displaying the Stored Value
Push the memory retrieve button 11 in order to display the value stored in the memory. “M=” is indicated in the display. When the memory contents “M=” is indicated in the display, it can be doubled by pushing the memory add button 4 or set to zero by pushing the memory subtract button 3. Deleting the Memory
To delete the memory contents, first push the memory retrieve button 11, so that “M=” is indicated in the display. Then briefly press button 1; “M” is no longer indicated in the display.

Working Advice

General Information
The reception lens 17 and the laser beam outlet 16 must not be covered while taking measurement. The measuring tool must not be moved while taking a measurement (with the exception of the continuous measurement function). Therefore, place the measuring tool, as far as this is possible, against or on the measuring points. Measurement takes place at the center of the laser beam, even when target surfaces are sighted at an incline.
Influence Effects on the Measuring Range
The measuring range depends upon the light conditions and the reflection properties of the target surface. For improved visibility of the laser beam when working outdoors and when the sunlight is intense, use the laser viewing glasses 19 (accessory) and the laser target plate 20 (accessory), or shade off 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).

If required, use the laser target plate 20 (accessory) on these surfaces. Also, air layers with varying temperatures or indirectly received reflections can affect the measured value. Sighting with the Alingment Aid (see figure D) With the alignment aid 8, sighting over larger distances is a lot easier. For this, look alongside the aligning aid on the top side of the measuring tool. The laser beam runs parallel to this line of sight.

Troubleshooting – Causes and Corrective Measures

The measuring tool monitors the correct function for each measurement. When a defect is determined, only the symbol shown aside flashes in the display. In this case, or when the above mentioned corrective measures cannot correct an error, have the measuring tool checked by an after-sales service agent for Bosch power tools

Accuracy Check of 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 10metres; its length must be precisely known (e.g. the width of a room or a door opening). The measuring distance must be indoors; the target surface for the measurement must be smooth and reflect well.
• Measure the distance 10 times after another.

The deviation of the individual measurements from the mean value must not exceed ±3 mm (max.). Log the measurements, so that you can compare their accuracy at a later point in time.

Maintenance and Service

Maintenance and Cleaning
Store and transport the measuring tool only in the supplied protective pouch. 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 17 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 after-sales service centre for Bosch power tools. Do not open the measuring tool yourself. In all correspondence and spare parts orders, please always include the 10-digit article number given on the type plate of the measuring tool. In case of repairs, send in the measuring tool packed in its protective pouch 21.
