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 unrecognizable.

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 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 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 accidentally dazzle someone.
Do not use the measuring tool in explosive atmospheres that contain flammable liquids, gases or dust. Sparks may be produced inside the measuring tool, which can ignite dust or fumes.
Never leave the measuring tool unattended when switched on, and ensure the measuring tool is switched off after use. Others may be dazzled by the laser beam.
Keep the magnet away from implants and other medical devices, e.g. pacemakers or insulin pumps. The magnet generates a field that can impair the function of implants and medical devices.

Assembly

Inserting/Replacing Batteries

It is recommended that you use alkaline manganese or rechargeable batteries to operate the measuring tool. To open the battery compartment cover (2), press the locking mechanism (6) and fold the battery compartment cover-up. Insert the batteries/rechargeable batteries. When doing so, ensure that the polarity is correct and corresponds to the diagram on the battery compartment cover.

Battery Indicator

The battery indicator (g) always indicates the current battery status:

BOSCH-GIM-60-L-Professional-Digital-Slope-Meter-fig-13

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.
Make sure to switch the laser off before changing the batteries. An accidentally switched on laser can blind other persons.

Operation

Starting Operation

Protect the measuring tool from moisture and direct sunlight.
Do not expose the measuring tool to any extreme temperatures or variations in temperature. For example, do not leave it in a car for extended periods of time. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. The precision of the measuring tool may be compromised if exposed to extreme temperatures or variations in temperature.
Keep the supporting surfaces and contact edges of the measuring tool clean. Protect the measuring tool against shock and impact. Dirt particles or deformations can lead to faulty measurements.
Avoid hard knocks to the measuring tool or 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 and Calibration of the Measuring Tool”.

Setting Up/Attaching the Measuring Tool

To measure or transfer grades, the measuring tool can not only be placed on or against surfaces, but can also be set up or attached in various ways.

Setting up with the Levelling Mechanics (e.g. on Uneven Floors) (see figure B):

Briefly push against the stand (13) to extend it. Press the button (3) to extend the levelling foot (12). Adjust the height of the levelling foot by turning the adjusting screw (4) so that the laser beam runs along the surface to be measured or the desired grade is displayed as the measured value (d).
For work without levelling mechanics, retract the stand (13) and levelling foot (12). For this, press both parts of the stand (➀) together and then slide the stand (13) into the measuring tool (➁) until it can be heard to engage. To retract the leveling foot (12), press the switch (5) to the side.

Fastening to the Tripod

Position the measuring tool with the 1/4″ tripod mount (11) onto the quick-change plate of the tripod or any other commercially available camera tripod. Tighten the measuring tool with the quick-change plate locking screw.

Attachment with Magnets:

Attach the measuring tool to a sufficiently magnetic object using the magnets (10).
Check that the measuring tool is firmly secured. Measuring tools that are not securely attached can fall off and injure yourself or others. The impact from a fall can damage the measuring tool or result in other forms of damage.

Attachment with Fastening Straps (see figure C):

BOSCH-GIM-60-L-Professional-Digital-Slope-Meter-fig-5

Thread the fastening straps (24) through the openings (25) and attach the measuring tool with both straps to a pipe or similar. Make sure that the hook and loop attachment of the strap end is pressed against the fastening strap. For thin pipes, thread the fastening strap through the openings with the smooth side facing outwards and wrap it once more around the measuring tool; for thick pipes, thread the fastening strap through the openings with the smooth side facing inwards.
Always secure the measuring tool with both fastening straps and check the tight seating of the straps. The retention force of the straps depends on the nature of the material that they are being fastened to. Loosely attached measuring tools can slip off and become damaged or result in other forms of damage.
Do not allow children to use the fastening straps without supervision. Misuse of the fastening straps may result in injury.

Switching On and 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.
To switch the measuring tool on or off, press the on/off button (19).
If no button on the measuring tool is pressed for approx. 30 min or the grade of the measuring tool is not changed by more than 1.5°, then grade measurement and the display are automatically switched off to save the batteries.

Switching the Laser On and Off

To switch on the laser beam, press the laser on/off button (16).
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 laser beam, press the laser on/off button again (16).
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.
When not using the laser, switch it off in order to save energy.

Changing the Measuring Unit (see figure A)

You can change between the units of measure “°”, “%” and “mm/ m” at any time. For this, press the button for changing the unit of measure (20) as many times as needed for the required unit of measure to be displayed in the indicator (c) or (f). The current measured value (d) will be automatically converted.
The unit-of-measure setting is retained when switching the measuring tool on or off.

Switching the Audio Signal On and Off

The audio signal can be switched on or off with the audio signal button (17). When the audio signal is switched on, the indicator for the audio signal (h) appears in the display.
When you switch on the measuring tool, the audio signal is switched on as standard.

Measured Value Indicator and Alignment Aids

With each movement of the measuring tool, the measured value (d) is updated. If the measuring tool has been moved significantly, wait until the measured value no longer changes before taking note of the value.
Depending on the position of the measuring tool, the measured value and the unit of measure are indicated in the display rotated by 180°. Thus, the indicator can also be read when working overhead.
The measuring tool uses alignment aids (a) on the display toshow in which direction it has to be tilted in order to reach the target value. In standard measurements, the target value is the horizontal or vertical; in the Hold/Copy function, it is the stored measured value; and when using a changed zero point, it is the stored zero point.
If the target value is reached, the arrows for the alignment aids (a) go out and, provided the audio signal is switched on, a continuous audio signal will be played.

Measuring Functions

Holding/Copying a Measured Value (see figure D)

With the button Hold/Copy (22), two functions can be controlled:

Hold a measured value, even if the measuring tool is subsequently moved (e.g. because the measuring tool is in a position in which the display is difficult to read);
Copy a measured value.

Hold function

Briefly press the button Hold/Copy (22). The current measured value (d) is held on the display and stored, and the indicator H flashes.
Press the button Hold/Copy (22) again to end the hold function. The stored value is deleted. Normal measurement is continued.

Copy function

Press and hold the button Hold/Copy (22). The current measured value (d) and the indicator H flash.
The measured value can be readjusted as long as the measured value flashes (three seconds). Press the button for changing the unit of measure (20) to increase the value and press the button Cal (21) to decrease the value.
If the measured value is not corrected, it will flash for three seconds, then it will be stored and subsequently move to the current measurement. The indicator H is shown continuously on the display.
To retrieve the copied value, briefly press the button Hold/ Copy (22) again.
Place the measuring tool in the location to which the measured value is to be transferred. When doing so, the alignment of the measuring tool is irrelevant. The alignment aids (a) show which direction the measuring tool has to be moved in to reach the grade you want to copy. When the stored grade is reached, an audio signal sounds and the alignment aids (a) go out.
Briefly press the button Hold/Copy (22) again to return to normal measurement. The indicator H is shown continuously on the display.
Press and hold the button Hold/Copy (22) to save a new value.
To delete a hold value, briefly press the on/off button (19).

Changing the Zero Point

For easier checking of grades (e.g. 45°), the zero point of a measurement can be changed. Align the measuring tool by placing it against a reference workpiece so that the desired new zero point is displayed as the measured value (e.g. 45.1°). Press the button Alt 0° (18). The measured value (d) and the indicator for a changed zero point (e) flash.

Roughly measured values can be corrected as long as the measured value (d) flashes: To increase the saved value, press the button for increasing the display value (20); to decrease the value, press the button for decreasing the display value (21) (e.g. from 45.1° to 45.0°). Three seconds after the last button actuation, the displayed grade value is saved as the new reference value.

In the measuring indicator (d), the current measured value is shown based on the new zero point, and the alignment aids and audio signals are based on the new zero point. Example: At a grade of 43.8° in relation to the horizontal surface and a stored zero point of 45°, 1.2° is shown as the measured value. To return to the standard zero point 0°, briefly press the on/off button (19). When doing so, the hold value will also be deleted.

Contact-Free Measuring/Transferring of Grades

With the laser, it is possible to measure and transfer grades contact- free, even over greater distances.

Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself (even from a distance).
Always use the centre of the laser point for marking. The size of the laser point changes with the distance.

To measure grades, align the measuring tool so that the laser beam runs alongside the surface to be measured. To transfer grades, align the measuring tool so that the desired grade is displayed as the measured value (d), and mark the grade on the target surface using the laser point.

Note: When transferring grades via the laser, take into consideration that the laser comes out 30 mm above the bottom edge of the measuring tool.

Accuracy Check and Calibration of the Measuring Tool

Checking the Measuring Accuracy (see figure E)

BOSCH-GIM-60-L-Professional-Digital-Slope-Meter-fig-7

Check the accuracy of the measuring tool prior to critical measurements, after intense variations in temperature as well as after heavy impact.

Before measuring grades < 45°, the accuracy check should take place on a level and roughly horizontal surface; before measuring grades > 45°, on a level and roughly vertical surface. Switch on the measuring tool and place it on the horizontal/vertical surface. Select the measuring unit ° (see “Changing the Measuring Unit (see figure A)”. Wait for ten seconds and note down the measured value. Rotate the measuring tool by 180° around its vertical axis. Wait again for ten seconds and note down the second measured value.

Calibrate the measuring tool only when the difference between both measured values is greater than 0.1°

Calibrate the measuring tool in the position (vertical or horizontal), in which the difference of the measured values has been determined.

Calibration for Horizontal Surfaces (see figure F)

The surface onto which you place the measuring tool must not deviate from the horizontal surface by more than 5°. If the deviation is greater, the calibration process is discontinued with the indicator ‑‑‑.

BOSCH-GIM-60-L-Professional-Digital-Slope-Meter-fig-9

Switch on the measuring tool and position it on the horizontal surface so that the spirit level for horizontal alignment (1) faces upwards and the display (7) faces you. Wait for ten seconds.
Then press the calibration button Cal (21) for approx. two seconds until CAL1 appears briefly on the display. Then the measured value will flash on the display.
Turn the measuring tool 180° around the vertical axis so that the spirit level still faces upwards but the display (7) is facing away from you. Wait for ten seconds.
Then press the calibration button Cal (21) again. CAL2 will be shown briefly on the display. Then the measured value (no longer flashing) will appear on the display. The measuring tool has now been recalibrated for this supporting surface.
Afterwards you must calibrate the measuring tool for the opposite surface. Rotate the measuring tool around the horizontal axis so that the spirit level for horizontal alignment (1) faces downwards and the display (7) faces you. Place the measuring tool on the horizontal surface. Wait for ten seconds.
Then press the calibration button Cal (21) for approx. two seconds until CAL1 appears briefly on the display. Then the measured value will flash on the display.
Turn the measuring tool 180° around the vertical axis so that the spirit level still faces downwards but the display (7) is facing away from you. Wait for ten seconds.
Then press the calibration button Cal (21) again. CAL2 will be shown briefly on the display. Then the measured value (no longer flashing) will appear on the display. The measuring tool has now been recalibrated for both horizontal supporting surfaces.

Note: If the measuring tool is not turned around the axis shown in the figure in steps ➂ and ➆, then the calibration cannot be completed (CAL2 is not indicated in the display).

Calibration for Vertical Surfaces (see figure G)

The surface onto which you place the measuring tool must not deviate from the vertical surface by more than 5°. If the deviation is greater, the calibration process is discontinued with the indicator ‑‑‑.

BOSCH-GIM-60-L-Professional-Digital-Slope-Meter-fig-11

Switch on the measuring tool and position it on the vertical surface so that the spirit level for vertical alignment (8) faces upwards and the display (7) faces you. Wait for ten seconds.
Then press the calibration button Cal (21) for approx. two seconds until CAL1 appears briefly on the display. Then the measured value will flash on the display.
Turn the measuring tool 180° around the vertical axis so that the spirit level still faces upwards but the display (7) is facing away from you. Wait for ten seconds.
Then press the calibration button Cal (21) again. CAL2 will be shown briefly on the display. Then the measured value (no longer flashing) will appear on the display. The measuring tool has now been recalibrated for this supporting surface.
Afterwards you must calibrate the measuring tool for the opposite surface. Rotate the measuring tool around the horizontal axis so that the spirit level for vertical alignment (8) faces downwards and the display (7) faces you. Place the measuring tool against the vertical surface. Wait for ten seconds.
Then press the calibration button Cal (21) for approx. two seconds until CAL1 appears briefly on the display. Then the measured value will flash on the display.
Turn the measuring tool 180° around the vertical axis so that the spirit level still faces downwards but the display (7) is facing away from you. Wait for ten seconds.
Then press the calibration button Cal (21) again. CAL2 will be shown briefly on the display. Then the measured value (no longer flashing) will appear on the display. The measuring tool has now been recalibrated for both vertical supporting surfaces.

Note: If the measuring tool is not turned around the axis shown in the figure in steps ➂ and ➆, then the calibration cannot be completed (CAL2 is not indicated in the display).
