4. Setup

4.1. Battery Installation

The GRL 600 CHV supports both Bosch Professional 18V batteries and D-cell batteries via an adapter (Dual Power system).

• Open the battery compartment cover.
• Insert the charged 18V battery pack or the D-cell battery adapter with 4x D-cell batteries, ensuring correct polarity.
• Close the battery compartment cover securely.

Figure 4.1: The GRL 600 CHV features a Dual Power system, allowing use of both Li-ion battery packs and 4x D-cell batteries.

Figure 4.2: The GRL 600 CHV is part of the Bosch Professional 18V System, ensuring compatibility with other 18V tools.

4.2. Tripod Assembly (BT 170 HD)

1. Extend the tripod legs to the desired height.
2. Ensure the tripod is stable and level on the ground.
3. Adjust the height of the center column using the crank.

4.3. Mounting the Laser Level

• Place the GRL 600 CHV onto the tripod's mounting plate.
• Secure the laser level using the tripod's locking screw.
• For vertical applications, use the included wall mount/bracket if needed.

5. Operating Instructions

5.1. Powering On and Self-Leveling

• Press the On/Off button to power on the device.
• The laser will automatically self-level. This process is indicated by a flashing laser beam. Once leveled, the beam will become steady.
• If the device is outside its self-leveling range, an error indicator will appear, and the laser will not rotate. Adjust the tripod until it is within range.

5.2. Operating Modes

The GRL 600 CHV offers various operating modes:

• Horizontal Mode: Projects a continuous 360° horizontal laser plane. Ideal for general leveling tasks.
• Vertical Mode: Projects a vertical laser plane. Useful for aligning walls, plumbing, or squaring.
• Slope Mode: Allows for manual or semi-automatic setting of slopes in X and Y axes.
• Spot Mode: Projects a single laser dot for precise point transfer.

Use the buttons on the control panel or the RC 6 remote control to switch between modes and adjust settings.

5.3. Using the Laser Receiver (LR 60)

For outdoor use or over long distances, the LR 60 laser receiver is essential:

1. Turn on the LR 60 receiver.
2. Move the receiver along the measuring rod in the path of the laser beam.
3. The display and audible signals on the receiver will indicate when it is precisely at the laser plane.

5.4. Using the Measuring Rod (GR 240)

The GR 240 measuring rod is used in conjunction with the laser receiver to determine height differences and transfer levels.

• Extend the sections of the measuring rod.
• Attach the laser receiver to the clamp on the measuring rod.
• Read the measurement directly from the scale on the rod once the receiver indicates the laser plane.

6. Maintenance

6.1. Cleaning

• Keep the laser level, tripod, and accessories clean.
• Wipe off dirt and dust with a damp, soft cloth. Do not use harsh cleaning agents or solvents.
• Regularly clean the laser exit aperture to ensure optimal performance.
