Included Components

Your BOSCH GOL26 26X Automatic Optical Level package includes the following items:

• Automatic Optical Level (BOSCH GOL26)
• Plumb Bob
• Hard Carrying Case
• Tool Kit (for adjustments)
• Lens Cap

Setup

Proper setup is crucial for accurate measurements. Follow these steps to prepare your optical level for use:

1. Unpacking: Carefully remove the optical level and all accessories from the hard carrying case.
2. Mounting: Securely mount the optical level onto a stable tripod. Ensure the tripod is placed on firm ground to prevent movement during operation.
3. Rough Leveling: Adjust the tripod legs to bring the circular bubble vial as close to the center as possible. The 90-degree mirror aids in viewing the bubble from various angles.
4. Fine Leveling: Use the precise leveling screws on the base of the instrument to center the bubble precisely within the circular vial. This ensures the instrument is perfectly level for accurate readings.
5. Compensator Check: The self-leveling compensator will automatically adjust the line of sight. Ensure the transport lock is disengaged before use.

Operating Instructions

The BOSCH GOL26 is designed for straightforward operation, providing accurate measurements for various tasks.

1. Sighting: Look through the eyepiece and use the top mount quick sight for initial targeting of the leveling rod.
2. Focusing: Adjust the focus knob until the leveling rod's graduations are sharp and clear. The 26x power lens and large aperture provide excellent magnification and a bright image.
3. Reading Measurements: Use the horizontal and vertical crosshairs to align with the desired point on the leveling rod. The stadia lines can be used for estimating distances.
4. Horizontal Angle Measurement: The horizontal circle with easy-to-read graduations allows for precise angle determination in one-degree increments with fine control adjustment.
5. Magnetic Dampening System: The integrated magnetic dampening system quickly settles the compensator, reducing the effects of jobsite vibrations and ensuring stable readings.
