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.
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.
When operating the measuring tool, loud signal tones may sound under certain circumstances. For this reason, keep the measuring tool away from your ears and from other persons. The loud sound can damage hearing.
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 (11), press on the locking mechanism (10) 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.
The battery indicator (2) always indicates the current battery status:

LED Capacity
Green continuous light 100−75 %
Yellow continuous light 75−35 %
Red continuous light 35−10 %
No light Batteries drained

If the batteries are running low, the laser lines will gradually become dimmer.
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.

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 15). 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 15).
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). As soon as it is switched on, the measuring tool emits laser lines from the outlet apertures (1).

u 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 pendulum unit is locked when the tool is switched off.
u 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 40 °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.
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 Function If no button on the measuring tool is pressed for approx. 120 min, the measuring tool will automatically switch itself off to preserve battery life.
To switch the measuring tool back on after it has been automatically switched 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 function, switch the measuring tool off and on again.
Deactivating the Signal Tone Function The signal tone function is always activated once the measuring tool is switched on.
To deactivate or activate the signal tone function, simultaneously press the laser mode button (6) and the receiver mode button (4) and hold them down for at least 3 s.
Three short signal tones will sound as confirmation both when the signal tone function is activated and deactivated.

Operating Modes
The measuring tool has several operating modes which you can switch between 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 and 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 with both automatic levelling or the pendulum lock.

Receiver Mode
Receiver mode must be activated when working with the laser receiver (18), regardless of which operating mode is selected. In receiver mode, the laser lines flash at a very high frequency, enabling them to be detected by the laser receiver (18). To switch on receiver mode, press the receiver mode button (4). The receiver mode indicator (5) will light up green. When receiver mode is switched on, the laser lines are less visible to the human eye. Therefore, switch receiver mode off by pressing the receiver mode button (4) again to work without a laser receiver. The receiver mode indicator (5) will go out.

Automatic Levelling
Working with Automatic Levelling Position the measuring tool on a level, firm surface or attach it to the universal holder (16) or the tripod (21). 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 ±4°. 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 4° from the horizontal plane, the laser lines will begin to flash quickly. If the signal tone function is activated, rapid signal tones will sound. Place the measuring tool in a horizontal position and wait for self-levelling to take place. As soon as the measuring tool is within the self-levelling range of ±4°, the laser beams will light up continuously and the signal tones will cease. In case of ground vibrations or position changes during operation, the measuring tool is automatically levelled again. Upon re-levelling, check the position of the horizontal or vertical laser line with regard to the reference points to avoid errors by moving the measuring tool.

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 (3) lights up red and the laser lines continuously flash slowly. For work with the pendulum lock, the 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 lines 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. In order to minimise thermal influences resulting from heat rising from the floor, it is recommended that you use the measuring tool on a tripod. In addition, position the measuring tool 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 levelling accuracy of the horizontal laser line, 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 Transverse Axis
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 a tripod, or place it on a firm, flat surface. Switch on the measuring tool in the mode with automatic levelling. Select the operating mode for generating a horizontal laser plane and a vertical laser plane directly in front of the measuring tool.

BOSCH GLL 3-80 Professional Instruction Manual - Accuracy Check of the
Measuring Tool

The maximum permitted deviation on the measuring distance of 2 × 5 m = 10 m is as follows: 10 m × ±0.3 mm/m = ±3 mm. The discrepancy d between points and must therefore amount to no more than 3 mm. Checking the Levelling Accuracy of the Vertical Lines
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 a tripod). Switch on the measuring tool in the mode with automatic levelling. Select the operating mode for generating a vertical laser plane directly in front of the measuring tool.

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.
Repeat the measuring process for the two vertical laser planes. To do this, select the operating mode for generating a vertical laser plane to one side of the measuring tool and rotate the measuring tool by 90° before beginning the measuring process.
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 line must be used for marking. The width of the laser line changes depending on the distance.
Working with the Laser Target Plate The laser target plate (17) improves visibility of the laser beam in unfavourable conditions and at greater distances. The reflective surface of the laser target plate (17) 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 A tripod offers a stable, height-adjustable support surface for measuring. Place the measuring tool with the 1/4″ tripod mount (8) on the thread of the tripod (21) or a conventional camera tripod. Use the 5/8″ tripod mount (9) to secure the measuring tool on a conventional building tripod. Tighten the measuring tool using the locking screw of the tripod. Roughly align the tripod before switching on the measuring tool.
Attaching with the Universal Holder (see figure B) You can secure the measuring tool, for example, on vertical surfaces or magnetisable materials using the universal holder (16). The universal holder is also suitable for use as a floor stand and facilitates the height adjustment of the measuring tool.
Keep your fingers away from the rear side of the magnetic accessory while attaching the accessory to surfaces. The strong pulling force of the magnets may jam your fingers.
Roughly align the universal holder (16) before switching on the measuring tool.
Working with the Laser Receiver (see figure B) Use the laser receiver (18) to improve detection of the laser lines in adverse lighting conditions (bright environment, direct sunlight) and over greater distances. When working with the laser receiver, switch on receiver mode (see “Receiver Mode”, page 15).
Laser Goggles 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 AF) Examples of possible applications for the measuring tool can be found on the graphics pages.
