Safety Notes

All instructions must be read and observed in order to work safely with the measuring tool. The integrated protections in the measuring tool may be compromised if the measuring tool is not used in accordance with the instructions provided. Never make warning signs on the measuring tool unrecognisable. STORE THESE INSTRUCTIONS IN A SAFE PLACE AND INCLUDE THEM WITH THE MEASURING TOOL WHEN GIVING IT TO A THIRD PARTY.

Caution – The use of other operating or adjusting equipment or the application of other processing methods than those mentioned here can lead to dangerous radiation exposure.
The measuring tool is provided with a warning label (marked with number 12 in the representation of the measuring tool on the graphics page).
If the text of the 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, not even from a distance. You could blind somebody, cause accidents or damage your eyes.
If laser radiation strikes your eye, you must deliberately close your eyes and immediately turn your head away from the beam.
Do not make any modifications to the laser equipment.
Do not use the laser viewing glasses as safety goggles. The laser viewing glasses are used for improved visualisation of the laser beam, but they do not protect against laser radiation.
Do not use the laser viewing glasses as sun glasses or in traffic. The laser viewing glasses do not afford complete UV protection and reduce colour perception.
Have the measuring tool repaired only through qualified specialists using original spare parts. This ensures that the safety of the measuring tool is maintained.
Do not allow children to use the laser measuring tool without supervision. They could unintentionally blind other persons or themselves.
Do not operate the measuring tool in explosive environments, such as in the presence of flammable liquids, gases or dusts. Sparks can be created in the measuring tool which may ignite the dust or fumes.
Loud audio signals will sound under certain conditions while operating the measuring tool. Therefore, keep the measuring tool away from your ear or other persons. The loud audio signal can cause hearing damage.
Keep the measuring tool, the laser target plate 18 and the universal holder 15 away from cardiac pacemakers. The magnets inside the measuring tool, the laser target plate and the universal holder generate a field that can impair the function of cardiac pacemakers.
Keep the measuring tool, the laser target plate 18 and the universal holder 15 away from magnetic data carriers and magnetically sensitive devices. The effect of the magnets inside the measuring tool, the laser target plate and the universal holder can lead to irreversible data loss.

Technical Data

Line laser	GLL 3-80
Article number	3 601 K63 S..

1) The working range can be decreased by unfavourable environmental conditions (e.g. direct sun irradiation).
The measuring tool can be clearly identified with the serial number 13 on the type plate.

Assembly

Inserting/Replacing the Batteries
Alkali-manganese batteries are recommended for the measuring tool.
To open the battery lid 11, pull on the latch 10 and remove the battery lid. Insert the batteries. When inserting, pay attention to the correct polarity according to the representation on the inside of the battery compartment.
The battery indicator 2 always indicates the current battery status:

Indication	Capacity
Continuous lighting, green	100–75 %
Continuous lighting, yellow	75–35 %
Continuous lighting, red	35–10 %
No light	Batteries empty

If the batteries are running low, the laser lines will gradually become dimmer.
Always replace all batteries at the same time. Only use batteries from one brand and with the identical 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 selfdischarge.

Operation

Initial Operation

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 a long time. 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 or falling of the measuring tool. After heavy exterior impact on the measuring tool, an accuracy check should always be carried out before continuing to work (see “Levelling Accuracy”).
Switch the measuring tool off during transport. When switching off, the levelling unit is locked. Else it can be damaged in case of intense movement.

Switching On and Off
To switch on the measuring tool, slide the On/Off switch 7 to the “ On” position (when working without automatic levelling) or to the “ On” position (when working with automatic levelling). Immediately after switching on, the measuring tool sends laser beams out of the exit openings 1.

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.
To switch off the measuring tool, slide the On/Off switch 7 to the “Off” position. When switching off, the levelling unit is locked.
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.

When exceeding the maximum permitted operating temperature of 40°C, the measuring tool switches off to protect the laser diode. After cooling down, the measuring tool is ready for operation and can be switched on again.
If the temperature of the measuring tool is approaching the maximum permissible operating temperature, the laser lines will gradually become dimmer.

Deactivating the Automatic Shut-off
When no button on the measuring tool is pressed for approx.
120 minutes, the measuring tool automatically switches off to save the batteries.
To switch the measuring tool back on after automatic shut-off, you can either slide the On/Off switch 7 to the “Off” position first and then switch the measuring tool back on, or press either the laser mode button 6 or the receiver mode button 4 once.
To deactivate the automatic shut-off function, hold down the laser mode button 6 for at least 3 s (with the measuring tool switched on). If the automatic shut-off function is deactivated, the laser beams will flash briefly as confirmation.
To activate the automatic shut-off, switch the measuring tool off and then on again.
Deactivating the Signal Tone
After the measuring tool has been switched on, the audio signal is always activated.
To deactivate or activate the audio signal, simultaneously press the laser mode button 6 and the receiver mode button 4 and hold them down for at least 3 s.
The audio signal activation and deactivation are both confirmed by three short beeps.
Operating Modes
The measuring tool has several operating modes between which you can switch at any time. These are for:

Generating a horizontal laser plane,
Generating a vertical laser plane,
Generating two vertical laser planes,
Generating a horizontal laser plane as well as two vertical laser planes.

After you switch it on, the measuring tool generates a horizontal laser plane. To change the operating mode, press the laser mode button 6.
All operating modes can be selected both with and without automatic levelling.
Receiver mode
Receiver mode must be activated to work with the laser receiver 16 – regardless of which operating mode is selected. In receiver mode the laser lines flash at very high frequency, enabling them to be detected by the laser receiver 16.
To switch on receiver mode, press button 4. Indicator 5 will light up green.
When receiver mode is switched on, the laser lines are less visible to the human eye. For this reason, switch receiver mode off by pressing button 4 again to work without a laser receiver. Indicator 5 will extinguish.

Automatic Levelling

Working with Automatic Levelling
Position the measuring tool on a level and firm support, attach it to the holder 15 or to the tripod 23.
When working with automatic levelling, push the On/Off switch 7 to the “ On” position.
After switching on, the levelling function automatically compensates irregularities within the self-levelling range of ±4°. The levelling is finished as soon as the laser beams do not move any more.
If automatic levelling is not possible, e.g. because the surface on which the measuring tool stands deviates by more than 4° from the horizontal plane, the laser lines begin to flash rapidly. When the audio signal is activated, a fast-beat signal sounds.
Set up the measuring tool in level position and wait for the self-levelling to take place. As soon as the measuring tool is within the self-levelling range of ±4°, all laser beams light up continuously and the audio signal is switched off.
In case of ground vibrations or position changes during operation, the measuring tool is automatically levelled in again. To avoid errors, check the position of the horizontal and vertical laser line with regard to the reference points upon relevelling.
Working without Automatic Levelling
For work without automatic levelling, slide the on/off switch 7 to the “ On” position. When automatic levelling is switched off, the indicator 3 lights up red and the laser lines continuously flash slowly.
When automatic levelling is switched off, you can hold the measuring tool freely in your hand or place it on an inclined surface. The laser lines no longer necessarily run perpendicular to each other.

Levelling Accuracy

Influences on Accuracy
The ambient temperature has the greatest influence. Especially temperature differences occurring from the ground upward can divert the laser beam.
Because the largest difference in temperature layers is close to the ground, the measuring tool should always be mounted on a tripod when measuring distances exceeding 20 m. If possible, also set up the measuring tool in the centre of the work area.
In addition to external influences, device-specific influences (e.g. falls or heavy impacts) can also lead to deviations. For this reason, check the levelling accuracy each time before beginning work.
Firstly, check the levelling accuracy of the horizontal laser line and then the levelling accuracy of the vertical laser lines.
Should the measuring tool exceed the maximum deviation during one of the tests, please have it repaired by a Bosch after-sales service.
Checking the Horizontal Levelling Accuracy of the Lateral Axis
For this check, a free measuring distance of 5 m on a firm surface between two walls A and B is required.

Mount the measuring tool onto a tripod, or place it on a firm and level surface close to wall A. Switch on the measuring tool to operation with automatic levelling. Select the operating mode in which a horizontal laser plane as well as a vertical laser plane in front of the measuring tool are generated.
Direct the laser against the close wall A and allow the measuring tool to level in. Mark the centre of the point where the laser lines cross each other at wall A (point I).
Turn the measuring tool by 180°, allow it to level in and mark the cross point of the laser lines on the opposite wall B (point II).
Without turning the measuring tool, position it close to wall B. Switch the measuring tool on and allow it to level in.
Align the height of the measuring tool (using a tripod or by underlaying, if required) in such a manner that the cross point of the laser lines is projected against the previously marked point II on the wall B.
Without changing the height, turn around the measuring tool by 180°. Direct it against the wall A in such a manner that the vertical laser line runs through the already marked point I. Allow the measuring tool to level in and mark the cross point of the laser lines on the wall A (point III).
The difference d of both marked points I and III on wall A results in the actual height deviation of the measuring tool alongside the lateral axis.

On the measuring distance of 2 x 5 m = 10 m, the maximum allowable deviation is: 10mx±0.2mm/m=±2mm.
Thus, the difference d between points I and III must not exceed 2 mm (max.).
Checking the Levelling Accuracy of the Vertical Lines
For this check, a door opening is required with at least 2.5 m of space (on a firm surface) to each side of the door.

Position the measuring tool on a firm, level surface (not on a tripod) 2.5 m away from the door opening. Switch on the measuring tool to operation with automatic levelling. Select an operating mode in which a vertical laser plane is generated in front of the measuring tool.
Mark the centre of the vertical laser line at the floor of the door opening (point I), at a distance of 5 m beyond the other side of the door opening (point II) and at the upper edge of the door opening (point III).
Rotate the measuring tool by 180° and position it on the other side of the door opening directly behind point II. Allow the measuring tool to level in and align the vertical laser line in such a manner that its centre runs exactly through points I and II.
Mark the centre of the laser line at the upper edge of the door opening as point IV.
The difference d of both marked points III and IV results in the actual deviation of the measuring tool to the plumb line.
Measure the height of the door opening.

Repeat the measuring procedure for the second vertical laser plane. For this, select an operating mode in which a vertical laser plane is generated aside of the measuring tool, and turn the measuring tool by 90° before beginning with the measuring procedure.
The maximum admissible deviation is calculated as follows: Doubled height of the door opening x 0.2 mm/m Example: For a door-opening height of 2 m, the maximum deviation may be 2 x 2 m x ±0.2 mm/m = ±0.8 mm. Consequently, points III and IV may be no more than 0.8 mm (max.) apart from each other for each of both measurements.

Working Advice

Always use the centre of the laser line for marking. The width of the laser line changes with the distance.
Working with the Laser Target Plate
The laser target plate 18 increases the visibility of the laser beam under unfavourable conditions and at large distances.
The reflective part of the laser target plate 18 improves the visibility of the laser line. Thanks to the transparent part, the laser line is also visible from the back side of the laser target plate.
Working with the Tripod (Accessory)
A tripod offers a stable, height-adjustable measuring support. Position the measuring tool with the 1/4″ tripod mount 8 onto the thread of the tripod 23 or a commercially available camera tripod. For fastening to a commercially available construction tripod, use the 5/8″ tripod mount 9. Tighten the measuring tool with the tripod mounting stud. Adjust the tripod roughly before switching on the measuring tool.
Fastening with the Universal Holder (Accessory)
(see figure B)
With the universal holder 15, you can fasten the measuring tool, e.g., to vertical surfaces, pipes or magnetisable materials.
The universal holder is also suitable for use as a ground tripod and makes the height adjustment of the measuring tool easier.
Adjust the universal holder roughly before 15 switching on the measuring tool.
Working with the Laser Receiver (Accessory)
(see figure B)
Use the laser receiver 16 to improve detection of the laser lines in adverse lighting conditions (bright environment, direct sunlight) and over greater distances.
Switch on receiver mode when working with the laser receiver (see “Receiver mode”, page 14).
Laser Viewing Glasses (Accessory)
The laser viewing glasses filter out the ambient light. This makes the red light of the laser appear brighter for the eyes.

Do not use the laser viewing glasses as safety goggles.
The laser viewing glasses are used for improved visualisation of the laser beam, but they do not protect against laserradiation.
Do not use the laser viewing glasses as sun glasses or in traffic. The laser viewing glasses do not afford complete UV protection and reduce colour perception.

Work Examples (see figures A – F)
Applicational examples for the measuring tool can be found on the graphics pages.
Always position the measuring tool close to the surface or edge you want to check, and allow it to level in prior to each measurement.
