Safety Instructions

All instructions must be read and observed in order for the measuring tool to function safely. The safeguards integrated into the measuring tool may be compromised if the measuring tool is not used in accordance with these instructions. Never make warning signs on the measuring tool unrecognisable. SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE AND INCLUDE THEM WITH THE MEASURING TOOL WHEN TRANSFERRING IT TO A THIRD PARTY.

Warning! If operating or adjustment devices other than those specified here are used or other procedures are carried out, this can lead to dangerous exposure to radiation.
The measuring tool is delivered with a laser warning sign (marked in the illustration of the measuring tool on the graphics page).
If the text of the laser 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. You could blind somebody, cause accidents or damage your eyes. u If laser radiation hits your eye, you must 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 goggles (accessory) as protective goggles. The laser goggles make the laser beam easier to see; they do not protect you against laser radiation.
Do not use the laser goggles (accessory) as sunglasses or while driving. The laser goggles do not provide full UV protection and impair your ability to see colours.
Have the measuring tool serviced only by a qualified specialist using only original replacement parts. This will ensure that the safety of the measuring tool is maintained.
Do not let children use the laser measuring tool unsupervised. They could unintentionally blind themselves or other persons.
Do not use the measuring tool in explosive atmospheres which contain flammable liquids, gases or dust. Sparks may be produced inside the measuring tool, which can ignite dust or fumes.
Keep the measuring tool and the magnetic accessories away from implants and other medical devices, e.g. pacemakers or insulin pumps. The magnets inside the measuring tool and accessories generate a field that can impair the function of implants and medical devices.
Keep the measuring tool and the magnetic accessories away from magnetic data storage media and magnetically sensitive devices. The effect of the magnets inside the measuring tool and accessories can lead to irreversible data loss.

Assembly

Inserting/changing the batteries
It is recommended that you use alkaline manganese batteries to operate the measuring tool. To open the battery compartment cover (3), press on the locking mechanism (2) and remove the battery compartment cover. Insert the batteries. When inserting the batteries, ensure that the polarity is correct according to the illustration on the inside of the battery compartment. If the status display (15) flashes, the batteries have to be replaced. Always replace all the batteries at the same time. Only use batteries from the same manufacturer and which have the same capacity.

▶ Take the batteries out of the measuring tool when you are not using it for a prolonged period of time. The batteries can corrode and self-discharge during prolonged storage in the measuring tool.

Working with the Rotating Platform (see figure A)
You can use the rotating platform (12) 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 on the rotating platform (12) so that the fastening grooves (13) of the rotating platform fit between the corresponding fastening grooves (6) on the bottom of the measuring tool. Turn the measuring tool clockwise to lock it on the rotating platform. Unscrew the legs of the rotating platform (12) with the height adjustment screws (10). Roughly align the rotating platform using the spirit level (8). If the measuring tool is mounted on the rotating platform (12), you can use the fine adjustment screw (11) to align vertical laser lines precisely with reference points.

Operation

Starting Operation

Protect the measuring tool from moisture and direct sunlight.
Do not expose the measuring tool to any extreme temperatures or fluctuations in temperature. For example, do not leave it in a car for extended periods of time. If it has been subjected to significant fluctuations in temperature, first allow the measuring tool to adjust to the ambient temperature and then always carry out an accuracy check before continuing work (see “Accuracy Check of the Measuring Tool”, page 9). The precision of the measuring tool may be compromised if exposed to extreme temperatures or fluctuations in temperature.
Avoid substantial knocks to the measuring tool and avoid dropping it. Always carry out an accuracy check before continuing work if the measuring tool has been subjected to severe external influences (see “Accuracy Check of the Measuring Tool”, page 9).
Switch the measuring tool off when transporting it. The pendulum unit is locked when the tool is switched off, as it can otherwise be damaged by big movements.
Switching On/Off
To switch on the measuring tool, slide the on/off switch (7) to the ” On” position (for working with the pendulum lock)
or to the “ On” position (for working with automatic levelling). The status display (15) lights up. Immediately after switching on, the measuring tool sends a horizontal laser line out of the front outlet aperture (1).
Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself (even from a distance).
To switch off the measuring tool, slide the on/off switch (7) to the “Off” position. The status indicator (15) goes out. The pendulum unit is locked when the tool is switched off.
Never leave the measuring tool unattended when switched on, and ensure the measuring tool is switched off after use. Others may be blinded by the laser beam.

If the maximum permitted operating temperature of 45 °C is exceeded, the tool shuts down to protect the laser diode. Once it has cooled down, the measuring tool is operational again and can be switched back on.

Deactivating the automatic shut-off function
The measuring tool automatically switches itself off after 30 min of operation.
To deactivate the automatic shut-off, hold down either the vertical mode button (16) or the horizontal mode button (17) for 3 seconds when switching on the measuring tool. The laser beams will flash briefly after 3 seconds if the automatic shut-off function is deactivated.
To activate the automatic shut-off function, switch the measuring tool off and on again (without holding down a button).

Operating Modes
The measuring tool has several operating modes, which you can switch between at any time. The horizontal and vertical modes can be switched on and off independently of each other. After switching on, the measuring tool is in horizontal mode. All operating modes can be selected with both automatic levelling or the pendulum lock.

Horizontal mode (see figure B)
In horizontal mode, the measuring tool sends out a horizontal laser line pointing forwards. To switch the horizontal laser line off or on, press the horizontal mode button (17).

Vertical mode and plumb point (see figures CD)
The measuring tool has two vertical operation modes:
– Vertical laser line forwards
– Vertical laser line forwards and to the right-hand side A plumb point is additionally projected downwards in vertical mode. To switch the vertical mode on/off or to change the vertical mode, press the vertical mode button (16) repeatedly until the required operating mode is reached.

Automatic Levelling
Working with automatic levelling Position the measuring tool on a level, firm surface or attach it to the rotating platform (12). For work with automatic levelling, slide the on/off switch (7)
to the ” On” position. The automatic levelling function automatically compensates irregularities within the self-levelling range of ±3°. The levelling is finished as soon as the laser lines stop moving. If automatic levelling is not possible, e.g. because the surface on which the measuring tool stands deviates by more than 3° from the horizontal plane, the laser beams will flash quickly. If this is the case, set up the measuring tool in a level position and wait for the self-levelling to take place. As soon as the measuring tool is within the self-levelling range of ±3°, the laser beams will light up continuously. In case of ground vibrations or position changes during operation, the measuring tool is automatically levelled again. Upon levelling, check the position of the laser beams with regard to the reference points to avoid errors arising from a change in the measuring tool’s position.

Working with the pendulum lock
For work with the pendulum lock, slide the on/off switch (7) to the “ On” position. The pendulum lock indicator (14) lights up red and the laser lines continuously flash slowly. For work with the pendulum lock, automatic levelling is switched off. You can hold the measuring tool freely in your hand or place it on a sloping surface. This means that the laser beams are no longer levelled and no longer necessarily run perpendicular to one another.

Accuracy Check of the Measuring Tool
Influences on Accuracy
The largest influence is exerted by the ambient temperature. In particular, temperature differences that occur from the ground upwards can refract the laser beam.
Since the temperature stratification is greatest at ground level, you should mount the measuring tool on a tripod and position it in the centre of the work surface, wherever this is possible.
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 the height accuracy and 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, you will need a free measuring distance of 5 m on firm ground between two walls (designated A and B).
Mount the measuring tool close to wall A on the rotating platform (12) or a tripod (24), or place it on a firm, flat surface. Switch on the measuring tool in the mode with automatic levelling. Switch on horizontal mode and vertical mode with a laser line forwards.

Height Accuracy of the Horizontal Line BOSCH GLL
3-15 X Professional Line Laser Instruction Manual - Checking the Height
Accuracy of the Horizontal Line

- Turn the measuring tool 180° without adjusting the height. Aim it at wall A such that the vertical laser line runs through the already marked point . Allow the measuring tool to level in and mark the point where the laser lines cross on wall A (point ).
- The discrepancy d between the two marked points and on wall A reveals the actual height deviation of the measuring tool.
The maximum permitted deviation on the measuring distance of 2 × 5 m = 10 m is as follows: 10 m × ±0.2 mm/m = ±2 mm. The discrepancy d between points and must therefore amount to no more than 2 mm.

Checking the Level Accuracy of the Horizontal Line
For this check, you will need a free area of 5 × 5 m.
- Mount the measuring tool in the middle between walls A and B on the rotating platform (12) or a tripod (24), or place it on a firm, flat surface. Switch on the measuring tool in the mode with automatic levelling. Switch on horizontal mode and allow the measuring tool to level in.

BOSCH GLL 3-15 X Professional Line Laser Instruction Manual - Checking the
Level Accuracy of the Horizontal Line

- Set up the measuring tool at a 5 m distance and rotated by 180° and allow it to level in.
- Align the height of the measuring tool (using the tripod or by placing objects underneath as required) so that the centre of the laser line exactly hits the previously marked point on wall B.
- Mark the centre of the laser line on wall A as point (vertically above or below point ).
- The discrepancy d between the two marked points and on wall A reveals the actual horizontal deviation of the measuring tool.
The maximum permitted deviation on the measuring distance of 2 × 5 m = 10 m is as follows: 10 m × ±0.2 mm/m = ±2 mm. The discrepancy d between points and must therefore amount to no more than 2 mm.
Checking the Level Accuracy of the Vertical Line
For this check, you will need a door opening (on solid ground) which has at least 2.5 m of space either side of the door.
– Place the measuring tool 2.5 m away from the door opening on a firm, flat surface (not on the rotating platform (12) or a tripod). Switch on the measuring tool in the mode with automatic levelling. Switch on vertical mode with a vertical laser line forwards and aim the vertical laser line at the door opening. Allow the measuring tool to level in.

BOSCH GLL 3-15 X Professional Line Laser Instruction Manual - Checking the
Level Accuracy of the Horizontal Line - Rotate the measuring tool 180° and position it on the other side of the door opening, directly behind point . Allow the measuring tool to level in and align the vertical laser line in such a way that its centre passes through points and exactly.
- Mark the centre of the laser line on the upper edge of the door opening as point .
- The discrepancy d between the two marked points and reveals the actual vertical deviation of the measuring tool.
- Measure the height of the door opening. You can calculate the maximum permitted deviation as follows: Doubled height of the door opening × 0.3 mm/m Example: At a door opening height of 2 m, the maximum deviation amounts to 2 × 2 m × ±0.3 mm/m = ±1.2 mm. The points and must therefore be no further than 1.2 mm from each other.

Working Advice
▶ Only the centre of the laser point or laser line must be used for marking. The size of the laser point/the width of the laser line changes depending on the distance.

Working with the Laser Target Plate
The laser target plate (22) improves visibility of the laser beam in unfavourable conditions and at greater distances.
The reflective surface of the laser target plate (22) improves visibility of the laser line. The transparent surface enables the laser line to be seen from behind the laser target plate.

Working with the Tripod (Accessory) (see figure F)
A tripod offers a stable, height-adjustable support surface for measuring. Place the measuring tool on the rotating platform (12) to assemble the measuring tool on a tripod.
Assembly on a 5/8″ tripod: Place the rotating platform with the 5/8″ tripod mount (9) on the thread of a commercially available 5/8″ tripod (24) or a commercially available building tripod. Tighten the rotating platform using the locking screw of the tripod.
Assembly on a 1/4″ tripod (see figure F): Screw the tripod adapter (18) (accessory) into the 5/8″ tripod mount (9) of the rotating platform. Place the tripod adapter with the 1/4″ tripod mount on the thread of a 1/4″ tripod (19) or a commercially available camera tripod. Tighten the tripod adapter using the locking screw of the tripod. Roughly align the tripod before switching on the measuring tool.

Laser Goggles (Accessory)
The laser goggles filter out ambient light. This makes the light of the laser appear brighter to the eye.

Do not use the laser goggles (accessory) as protective goggles. The laser goggles make the laser beam easier to see; they do not protect you against laser radiation.
Do not use the laser goggles (accessory) as sunglasses or while driving. The laser goggles do not provide full UV protection and impair your ability to see colours.

Example applications (see figures BE)
Examples of possible applications for the measuring tool can be found on the graphics pages.
