Included Components:

• Automatic Optical Level (GOL 32CK)
• Aluminum Tripod
• Grade Rod
• Plumb Bob
• Tool Kit
• Carrying Case
• Lens Cap

3. Setup and Assembly

Proper setup is crucial for accurate measurements. Follow these steps to assemble and prepare your optical level kit.

3.1 Setting up the Tripod

1. Extend the tripod legs to a suitable height, ensuring the tripod head is approximately at eye level when standing.
2. Spread the legs wide enough to provide a stable base, pressing the leg tips firmly into the ground if outdoors.
3. Ensure the tripod head is as level as possible by adjusting the leg lengths.

3.2 Mounting the Optical Level

1. Carefully remove the optical level from its carrying case.
2. Attach the optical level to the tripod head using the central screw. Tighten securely but do not overtighten.
3. Release the transport lock on the optical level to allow the compensator to self-level.

3.3 Initial Leveling

1. Use the circular bubble vial and its 90-degree mirror to roughly level the instrument. Adjust the three precision leveling screws on the base until the bubble is centered within the circle.
2. The self-leveling compensator will fine-tune the leveling once the bubble is within its operating range.

4. Operating Instructions

This section details the steps for operating your BOSCH GOL 32CK optical level for various measurement tasks.

4.1 Taking a Reading

1. Position the grade rod vertically at the point you wish to measure. Ensure it is held steady and plumb.
2. Look through the eyepiece of the optical level. Use the gun-sight on top of the level for initial alignment towards the grade rod.
3. Adjust the focus knob until the image of the grade rod and the crosshairs are sharp and clear.
4. Read the measurement on the grade rod where the central horizontal crosshair intersects it. Ensure you are using the correct crosshair for the reading.

4.2 Measuring Distances (Stadia Method)

The GOL 32CK features stadia lines for estimating distances. To use this method:

1. Take readings at both the upper and lower stadia lines on the grade rod.
2. Calculate the difference between the upper and lower stadia readings.
3. Multiply this difference by 100 to estimate the horizontal distance from the instrument to the rod.

4.3 Measuring Angles (Horizontal Circle)

The horizontal circle allows for measuring angles in 1-degree increments with fine-control adjustment.

1. Align the instrument with your starting point and set the horizontal circle to zero using the horizontal drive screw.
2. Rotate the instrument to your target point.
3. Read the angle indicated on the horizontal circle.

5. Maintenance and Care

Proper maintenance ensures the longevity and accuracy of your BOSCH GOL 32CK optical level.

5.1 Cleaning

• Keep the lens and optical components clean. Use a soft, lint-free cloth specifically designed for optics.
• For general cleaning of the instrument body, use a damp cloth. Avoid harsh chemicals or abrasive materials.
• Ensure no dust or debris enters the internal mechanisms.

5.2 Storage

• Always engage the transport lock before storing or transporting the optical level to protect the compensator.
• Store the instrument in its original carrying case in a dry, temperature-controlled environment.
• Avoid storing the level in direct sunlight or extreme temperatures.

5.3 Calibration Check

While the GOL 32CK is designed for durability and accuracy, it is recommended to periodically check its calibration, especially after significant impacts or prolonged use. Refer to professional surveying guides or contact Bosch service for detailed calibration procedures.
