5.2 Rotation Speeds and Scan Modes
Adjust the laser beam's rotation speed and scan mode using the control panel or remote control. Available rotation speeds are 0, 60, 120, 300, and 600 rpm. Scan modes include 0°, 10°, 45°, 90°, 180°, and 360° for precise beam control.
5.3 Dual-Slope Adjustment
For applications requiring a sloped laser line, the 8991 Prolaser allows for dual-slope adjustment of up to ±5° in both X and Y planes. Refer to the control panel diagram for the specific buttons used for slope adjustment.
5.4 Using the Laser Detector
For outdoor use or when the laser beam is not easily visible, utilize the included laser detector. The detector extends the working range of the laser level up to 300 meters (980 feet), providing audible and visual indications when the laser line is detected.

6. Manutenzione
Proper maintenance ensures the longevity and accuracy of your Kapro 8991 Prolaser.
6.1 Pulizia
Regularly clean the exterior of the laser level with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the housing or optical components. Keep the laser output window clean and free of dust or debris.
6.2 Conservazione
When not in use, store the Kapro 8991 Prolaser in its shock-resistant carrying case in a dry, cool environment. Remove batteries if the device will not be used for an extended period to prevent leakage.
6.3 Grado di protezione IP65
The Kapro 8991 Prolaser is IP65 rated, meaning it is protected against dust ingress and low-pressure water jets from any direction. While durable, it is not designed for submersion. Always ensure the battery compartment is securely closed to maintain the IP65 rating.
