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 (7), press the locking mechanism (8) and lift open 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 batteries become weak, the battery warning indicator (2) will flash green. The laser lines will also flash for approximately five seconds every ten minutes. The measuring tool can still be operated for approximately one hour after the first flash. If the batteries drain completely, the laser lines will flash one more time just before automatic shut-off.

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 RM 1 rotating mount (see figures A1–A3)

You can use the rotating mount (15) to rotate the measuring tool 360° around a central, always visible plumb point. This enables you to set up the laser lines without having to change the position of the measuring tool.

Place the measuring tool with the guide groove (9) on the guide rail (16) of the rotating mount (15) and slide the measuring tool all the way onto the platform.

To disconnect the measuring tool, pull it off the rotating mount in the opposite direction.

Rotating mount positioning options:

  • Standing on a flat surface,
  • Screwed to a vertical surface,
  • On metallic ceiling strips using the ceiling clip (19),
  • On metallic surfaces using the magnets (18).

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 20).

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 20).
▶ 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 (10) 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 beams from the outlet apertures (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 (10) to the Off position. 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 50^ 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.

Automatic shut-off

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 (10) 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 (5) once.

Temporarily Deactivating Automatic Shut-Off

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.

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

To activate the automatic shut-off function, switch the measuring tool off and on again.

Setting the Operating Mode

The measuring tool has several operating modes, which you can switch between at any time:

  • Cross-line and point mode: The measuring tool generates a horizontal and a vertical laser line as well as two vertical laser points, one facing up, the other down. The laser lines cross at a 90^ angle.
  • Horizontal line mode: The measuring tool generates a horizontal laser line in front of it.
  • Vertical line mode: The measuring tool generates a vertical laser line in front of it.

Positioning the measuring tool in the room displays the vertical laser line on the ceiling beyond the top laser point.

If the measuring tool is positioned directly against a wall, the vertical laser line almost encircles the entire space (360° line).

- Point mode: The measuring tool generates two vertical laser points, one facing up, the other down.

All operating modes, apart from point operation, can be selected with both automatic levelling or the pendulum lock. To change the operating mode, press the laser mode button (6).

Receiver Mode

Receiver mode must be activated when working with the laser receiver (23), 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 (23).

To switch on receiver mode, press the receiver mode button (5). The receiver mode indicator (3) 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 (5) again to work

20 | English

without a laser receiver. The receiver mode indicator (3) will go out.

Automatic Levelling

Working with Automatic Levelling (see figures B–E)

Position the measuring tool on a level, firm surface or attach it to the rotating mount (15).

For work with automatic levelling, slide the on/off switch (10) to the "bn" position.

The automatic levelling function automatically levels irregularities within the self-levelling range of ±4^ . The measuring tool has been levelled as soon as the laser beams stop flashing.

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 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 ±4^ , 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 a pendulum lock (see figure F)

For work with the pendulum lock, slide the on/off switch (10) to the "On" position. The pendulum lock indicator (4) 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 and the plumb accuracy.

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 a tripod, or place it on a firm, level surface. Switch on the measuring tool. Select cross-line mode with automatic levelling.

BOSCH GCL 250 Professional - Checking the Height Accuracy of the Horizontal Line - 1

text_image A B I 5 m

- Aim the laser at the closer wall A and allow the measuring tool to level in. Mark the middle of the point at which the laser lines cross on the wall (point I).

text_image A 180° B I II

- Turn the measuring tool 180^ , allow it to level in and mark the point where the laser lines cross on the opposite wall B (point II).

- Position the measuring tool – without rotating it – close to wall B, switch it on and allow it to level in.

BOSCH GCL 250 Professional - Checking the Height Accuracy of the Horizontal Line - 3

text_image A I B II

- Align the height of the measuring tool (using the tripod or by placing objects underneath as required) so that the point where the laser lines cross exactly hits the previously marked point II on wall B.

BOSCH GCL 250 Professional - Checking the Height Accuracy of the Horizontal Line - 4

text_image A III d I 180° B II
  • 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 I. Allow the measuring tool to level in and mark the point where the laser lines cross on wall A (point III).
  • The discrepancy d between the two marked points I and III 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 × ±0.3 mm/m = ±3 mm. The discrepancy d between points I and III must therefore amount to no more than 3 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 a tripod, or place it on a firm, level surface. Select horizontal line mode with automatic levelling and allow the measuring tool to level in.

BOSCH GCL 250 Professional - Checking the Level Accuracy of the Horizontal Line - 1

text_image A I 2.5 m 5.0 m B II

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

BOSCH GCL 250 Professional - Checking the Level Accuracy of the Horizontal Line - 2

text_image A I II III 5.0 m 2.5 m II B
  • 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 II on wall B.
  • Mark the centre of the laser line on wall A as point III (vertically above or below point I).
  • The discrepancy d between the two marked points I and III 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 × ±0.3 mm/m = ±3 mm. The discrepancy d between points I and III must therefore amount to no more than 3 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 2.5m away from the door opening on a firm, flat surface (not on a tripod). Select vertical line mode with automatic levelling. Aim the laser line at the door opening and allow the measuring tool to level in.

BOSCH GCL 250 Professional - Checking the Level Accuracy of the Vertical Line - 1

text_image III I II 2.5 m 2.5 m

22 | English

- Mark the centre of the vertical laser line on the floor of the door opening (point I), 5 m away on the other side of the door opening (point II) and on the upper edge of the door opening (point III).

BOSCH GCL 250 Professional - | English - 1

text_image III IV d 2m I II
  • Rotate the measuring tool 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 way that its centre passes through points I and II exactly.
  • Mark the centre of the laser line on the upper edge of the door opening as point IV.
  • The discrepancy d between the two marked points III and IV 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 III and IV must therefore be no further than 1.2 mm from each other.

Checking Plumb Accuracy

For this check, you will need a clear measuring space on firm ground with a distance of approx. 5 m between the floor and the ceiling.

- Mount the measuring tool onto the rotating mount (15) and place it on the floor. Select point mode and allow the measuring tool to level in.

BOSCH GCL 250 Professional - Checking Plumb Accuracy - 1

text_image I 5 m II

- Mark the centre of the top laser point on the ceiling (point I). Also mark the centre of the bottom laser point on the floor (point II).

BOSCH GCL 250 Professional - Checking Plumb Accuracy - 2

text_image d I III 180° II
  • Turn the measuring tool by 180^ . Position it so that the centre of the bottom laser point falls onto the marked point II. Allow the measuring tool to level in. Mark the centre of the top laser point (point III).
  • The discrepancy d between the two marked points I and III on the ceiling reveals the actual deviation of the measuring tool from the vertical plane.

You can calculate the maximum permitted deviation as follows:

Doubled distance between floor and ceiling × 0.7 mm/m Example: At a floor-to-ceiling distance of 5 m, the maximum deviation amounts to

2 × 5 m × ± 0.7 mm/m = ± 7 mm . The points I and III must therefore be no further than 7 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 (see figure L)

The laser target plate (21) improves visibility of the laser beam in unfavourable conditions and at greater distances. The reflective surface of the laser target plate (21) 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)

A tripod offers a stable, height-adjustable support surface for measuring. Place the measuring tool with the 1/4" tripod mount (11) on the thread of the tripod (24) or a conventional camera tripod. Use the 5/8" tripod mount (12) 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.

Securing with the universal holder (accessory) (see figure L)

Using the universal holder (20), you can secure the measuring tool on vertical surfaces, pipes or magnetizable materials, for example. The universal holder is also suitable for use

as a floor stand and facilitates height adjustment of the measuring tool.

Roughly align the universal holder (20) before switching on the measuring tool.

Working with the laser receiver (accessory)

Use the laser receiver (23) 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 19).

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 G-M)

Examples of possible applications for the measuring tool can be found on the graphics pages.

Always place the measuring tool close to the surface or edge that needs to be checked, and allow it to level in before the beginning of any measurement.

Always measure the distances between the laser beam and a surface or edge at two points that are as far from each other as possible.

Maintenance and Service

Maintenance and Cleaning

Keep the measuring tool clean at all times.

Never immerse the measuring tool in water or other liquids. Wipe off any dirt using a damp, soft cloth. Do not use any detergents or solvents.

The areas around the outlet aperture of the laser in particular should be cleaned on a regular basis. Make sure to check for lint when doing this.

Only store and transport the measuring tool in the protective bag (28) or the case (26).

If the measuring tool needs to be repaired, send it off in the protective bag (28) or the case (26).

- Postavite merni alat za 180° okrenut na 5 m udaljenosti i iznivelišite ga.

- Merni alat usmerite uvis tako (pomoću stativa ili po potrebi podmetanjem) da sredina laserske linije tačno pogađa prethodno označenu tačku II na zidu B.

- Označite na zidu A sredinu laserske linije kao tačku III (vertikalno iznad odn. ispod tačke I).

- Razlika d između obe označene tačke I i III na zidu A predstavlja stvarno odstupanje mernog alata od horizontale.

Na mernoj deonici od 2 × 5 m = 10 m maksimalno dozvoljeno odstupanje iznosi:

10 m × ±0,3 mm/m = ±3 mm. Razlika d između tačaka I i III prema tome sme da iznosi maksimalno 3 mm.

Kontrola tačnosti nivelisanja vertikalne linije

Za kontrolu potreban Vam je otvor od vrata, kod kojih (na čvrstoj zemlji) sa svake strane vrata ima najmanje 2,5 m prostora.

- Postavite merni alat na 2,5 m rastojanja od otvora vrata na čvrstu radnu podlogu (ne na stativ). Izaberite vertikalni linijski režim rada sa automatskim nivelisanjem. Usmerite lasersku liniju na otvor vrata i iznivelišite merni alat.
