Bosch GLM 40 Laser Measure User Manual

Introduction

This user manual provides detailed instructions for the safe and efficient operation of your Bosch GLM 40 Laser Measure. Please read this manual thoroughly before using the device to ensure proper handling and to maximize its performance. The Bosch GLM 40 is a compact and versatile laser distance meter designed for quick and accurate measurements of distances, areas, and volumes, suitable for various professional and DIY applications.

Safety Information

Always observe the following safety precautions to prevent injury and damage to the device.

Laser Safety

• CAUTION: Do not stare directly into the laser beam. The laser beam is Class 2 according to IEC 60825-1:2014.
• Do not intentionally direct the laser beam at people or animals.
• Avoid pointing the laser beam at reflective surfaces, as the reflected beam can also be harmful.
• Do not modify the laser device. Unauthorized modifications can increase the laser radiation.
• Ensure the laser is switched off when not in use.

General Safety

• Keep the device out of reach of children and unauthorized persons.
• Do not operate the device in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
• Use only the specified battery type (AAA). Ensure correct polarity when inserting batteries.
• Protect the device from moisture and direct sunlight.
• Do not open the device housing. Repairs should only be performed by authorized service personnel.

Setup

Inserting/Replacing Batteries

The Bosch GLM 40 requires two 1.5V AAA batteries. Ensure correct polarity when inserting.

1. Open the battery compartment cover on the back of the device.
2. Insert the two AAA batteries, matching the (+) and (-) symbols inside the compartment.
3. Close the battery compartment cover securely.

If the battery symbol appears on the display, the batteries are low and should be replaced soon.

Operating Instructions

Turning On/Off

• To Turn On: Press the Red Triangle button. The laser will activate immediately.
• To Turn Off: Press and hold the C/O button for approximately 2 seconds. The device will also automatically turn off after 5 minutes of inactivity to save battery.

Setting Measurement Reference Point

The GLM 40 can measure from the front edge or the rear edge of the device. The default is the rear edge.

• Press the Func button to toggle between front edge and rear edge measurement. An icon on the display will indicate the current reference point.

Single Distance Measurement

1. Turn on the device.
2. Point the laser beam at the target surface.
3. Press the Red Triangle button once. The measured distance will appear on the display.

Continuous Measurement (Tracking)

This mode allows you to see real-time distance updates as you move the device.

1. Turn on the device.
2. Press and hold the Red Triangle button for approximately 2 seconds. The device will start continuous measurement.
3. Move the device slowly towards or away from the target. The display will update the distance continuously.
4. Press the Red Triangle button again to stop continuous measurement and hold the last value.

Area Calculation

To calculate the area of a surface (e.g., a wall or floor):

1. Press the + button once. The area icon (square) will appear on the display.
2. Measure the first length (e.g., width) by pressing the Red Triangle button.
3. Measure the second length (e.g., height) by pressing the Red Triangle button again.
4. The calculated area in square meters (m²) will be displayed.

Volume Calculation

To calculate the volume of a space (e.g., a room):

1. Press the + button twice. The volume icon (cube) will appear on the display.
2. Measure the length by pressing the Red Triangle button.
3. Measure the width by pressing the Red Triangle button.
4. Measure the height by pressing the Red Triangle button.
5. The calculated volume in cubic meters (m³) will be displayed.

Indirect Height Measurement (Pythagoras Function)

This function allows you to measure heights that are difficult to access directly, using the Pythagorean theorem.

1. Press the - button once. The indirect height icon (triangle with question mark) will appear.
2. Measure the hypotenuse (distance from the device to the top of the object) by pressing the Red Triangle button. Ensure the device is level with the base of the object.
3. Measure the horizontal distance (from the device to the base of the object) by pressing the Red Triangle button again.
4. The calculated height will be displayed.

Accessing Measurement History

The GLM 40 stores the last 10 measurements.

• To view previous measurements, repeatedly press the Func button until the history icon appears.
• Use the + and - buttons to scroll through the stored values.

Maintenance

Cleaning

• Keep the device clean to ensure optimal performance.
• Wipe the device with a soft, damp cloth. Do not use harsh cleaning agents or solvents.
• Pay special attention to the laser exit aperture and receiver lens. Clean them gently with a soft, lint-free cloth, similar to cleaning camera lenses.

Storage

• Store the device in its protective pouch when not in use.
• If storing for extended periods, remove the batteries to prevent leakage.
• Store in a dry, dust-free environment, away from extreme temperatures.
