Safety Notes

Manual Icon a1 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 10 in the representation of the measuring tool on the graphics page).

[ Laser Radiation Class 2
do not stare into beam ]

IEC 60825-1:2014-05 <1mW, 630-650 nm

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.
Keep the measuring tool and the rotating mount 18 away from cardiac pacemakers. The magnets inside the measuring tool and the rotating mount generate a field that can impair the function of cardiac pacemakers.
Keep the measuring tool and the rotating mount 18 away from magnetic data media and magnetically sensitive equipment. The effect of the magnets inside the measuring tool and the rotating mount can lead to irreversible data loss.

Assembly

Inserting/Replacing the Batteries

Alkali-manganese batteries are recommended for the measuring tool.

To open the battery lid 7 , press the latch of the battery lid 8 in the direction of the arrow and remove the battery lid. Insert the supplied batteries. When inserting, pay attention to the correct polarity according to the representation on the inside of the battery compartment.

When the battery indication 4 flashes, the batteries are weak. When the battery indication flashes for the first time, the measuring tool can still be operated for approx. 1 h.

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 self-discharge.

Working with the Rotating Mount RM 1

(see figures J1J2)

You can use the rotating mount 18 to rotate the measuring tool 360° around a central, always visible plumb point. This enables you to set up the laser lines precisely, without having to change the position of the measuring tool.

– Place the measuring tool with the guide groove 21 on the guide rail 22 of the rotating mount 18 and slide the measuring tool to the stop onto the platform.
To disconnect, pull the measuring tool in the opposite direction from the rotating mount.

Positioning possibilities of the rotating mount:
– standing on a flat surface,
– screwed to a vertical surface,
– on metallic surfaces using the magnets 24 ,
– on metallic ceiling strips using the ceiling clip 19.

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, which can be damaged in case of intense movement, is locked.

Switching On and Off
To switch on the measuring tool, slide the On/Off switch 2 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 2 to the “Off” position. When switching off, the levelling unit is locked.

When exceeding the maximum permitted operating temperature of 50 °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.

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 2 to position “Off” first and then switch the measuring tool back on, or press either button 5 or button 6.

Deactivating the Automatic Shut-off:
– To deactivate automatic shut-off, hold down button 5 for at least 3 s with the measuring tool switched on. If automatic shut-off is deactivated, the laser lines will flash briefly as confirmation.

Note: If the operating temperature exceeds 45 ° C, automatic shut-off can no longer be deactivated.

Activating the Automatic Shut-off:
– To activate the automatic shut-off, switch the measuring tool off and then on again.

Operation Modes (see figures A – C)
The measuring tool has three operating modes, between which you can switch at any time:
– Horizontal operation “–” : generates a horizontal laser line,
– Vertical operation “l” : generates a vertical laser line,
– Cross line operation “–” and “l” : generates a horizontal and a vertical laser line.

Once the measuring tool has been switched on, it is in crossline operation. To change the operating mode, switch the horizontal or vertical laser line using button 5 or 6.

All three operating modes can be selected either with or without automatic levelling.

Working with Automatic Levelling
Position the measuring tool on a level and firm support, attach it to the holder 20 or to the tripod 15.

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 will begin to flash quickly.

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 re-levelling.

Working without Automatic Levelling
For work without automatic levelling, slide the On/Off switch 2 to position “ on”. When automatic levelling is switched off, the laser lines flash slowly.

When the automatic levelling is switched off, the measuring tool can be held by hand or placed on an inclined surface. In cross-line operation, the two laser lines do not necessarily run at a right angle 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.

As thermal fluctuation is largest close to the ground, the measuring tool, if possible, should be mounted on a commercially available tripod and placed in the centre of the working 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.

First, check both the height as well as the levelling accuracy of the horizontal laser line, then the levelling accuracy of the vertical laser line.

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 Height Accuracy of the Horizontal Line
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 the holder or a tripod, or place it on a firm and level surface close to wall A. Switch the measuring tool on.

BOSCH GLL 2-10 - Levelling Accuracy 1

– 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 on the wall (point I).

BOSCH GLL 2-10 - Levelling Accuracy 2

– 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.

BOSCH GLL 2-10 - Levelling Accuracy 3

– 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.

BOSCH GLL 2-10 - Levelling Accuracy 4

– 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 indicates the actual height deviation of the measuring tool.

The maximum permitted deviation dmax is calculated as follows:
dmax = double distance of the walls x 0.3 mm/m
Example: With a 5 metre distance between the walls, the maximum deviation must not exceed
dmax = 2 x 5 m x 0.3 mm/m = 3 mm. Thus, the marks must not be more than 3 mm apart.

Checking the Levelling Accuracy of the Horizontal Line
For the check, a free surface of approx. 5 x 5 metres is required.

– Mount the measuring tool between both walls A and B onto the holder or a tripod, or place it on a firm and level surface. Allow the measuring tool to level in.

BOSCH GLL 2-10 - Levelling Accuracy 5

– At a distance of 2.5 metres from the measuring tool, mark the centre of the laser line (point I on wall A and point II on wall B) on both walls.

BOSCH GLL 2-10 - Levelling Accuracy 6

– Set up the measuring tool 5 metres away turned by 180° 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 centre of the laser line is projected exactly against the previously marked point II on wall B.
– Mark the centre of the laser line as point III (vertically above or below point I) on the wall A.
– The difference d of both marked points I and III on wall A indicates the actual deviation of the measuring tool from the level plane.

The maximum permitted deviation dmax is calculated as follows:
dmax = double distance of the walls x 0.3 mm/m
Example: With a 5 metre distance between the walls, the maximum deviation must not exceed
dmax = 2 x 5 m x 0.3 mm/m = 3 mm. Thus, the marks must not be more than 3 mm apart.

Checking the Levelling Accuracy of the Vertical Line
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. Direct the laser beams at the door opening and allow the measuring tool to level in.

BOSCH GLL 2-10 - Levelling Accuracy 7

– 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).

BOSCH GLL 2-10 - Levelling Accuracy 8

– Position the measuring tool 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.
– The difference d between point III and the centre of the laser line at the upper edge of the door opening results in the actual deviation of the measuring tool from the vertical plane.
– Measure the height of the door opening.

The maximum permitted deviation dmax is calculated as follows:
dmax = double height of the door opening x 0.3 mm/m
Example: With a door opening height of 2 metres, the maximum permitted deviation is
dmax = 2 x 2 m x 0.3 mm/m = 1.2 mm. Thus, the marks must not be more than 1.2 mm apart.

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 Tripod (Accessory)
A tripod offers a stable, height-adjustable measuring support. Position the measuring tool with the 1/4″ tripod mount 12 on[1]to the thread of the tripod 15 or a commercially available cam[1]era tripod. For fastening to a commercially available construc[1]tion tripod, use the 5/8″ tripod mount 11. Tighten the measuring tool with the tripod mounting stud.

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 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.

Fastening with the Universal Holder (Accessory)
(see figure D)
With the universal holder 20 , 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 20 switching on the measuring tool.

Working with the Measuring Plate (Accessory)
(see figures G–H)
With the measuring plate 16 , it is possible to project the laser mark onto the floor or the laser height onto a wall.

With the zero field and the scale, the offset or drop to the required height can be measured and projected at another location. This eliminates the necessity of precisely adjusting the measuring tool to the height to be projected.

The measuring plate 16 has a reflective coating that enhances the visibility of the laser beam at greater distances or in intense sunlight. The brightness intensification can be seen only when viewing, parallel to the laser beam, onto the measuring plate.

Work Examples (see figures D–F)
Applicational examples for the measuring tool can be found on the graphics pages.
