5. Setup
5.1 Battery Installation and Charging
The device is powered by a removable 5200mAh Li-ion battery. Ensure the battery is fully charged before first use.
- Insert the charged Li-ion battery into the battery compartment on the side of the laser level.
- To charge, connect the provided Type-C power cord to the charging port on the battery or directly to the laser level. The battery can be charged separately.

5.2 Mounting the Laser Level
The GK011SG offers versatile mounting options:
- Tripod Mounting: The laser level has a 1/4"-20 mounting thread at the bottom, allowing it to be securely attached to a standard tripod (not included).
- Magnetic Bracket: Use the included 360° strong magnetic bracket to affix the laser tool to metallic surfaces. The bracket also features 1/4"-20 and 5/8"-11 mounting threads for compatibility with various tripods or laser pole mounts. Two nail holes on the bracket provide additional fixing methods.

6. Operating Modes
The Huepar Pro GK011SG features three primary operating modes: Self-Leveling, Manual, and Pulse Mode.
6.1 Self-Leveling Mode
When the pendulum is unlocked, the laser level will automatically self-level within a range of ±3°. If the device is outside this range, the laser beam will flash continuously to indicate it cannot self-level. Position the device on a stable, relatively level surface for accurate operation.
6.2 Manual Mode
To use the laser level at any angle, lock the pendulum. This disables the self-leveling function, allowing you to project lines at custom inclinations. The laser lines will not flash in this mode, indicating a locked pendulum.

6.3 Pulse Mode
For outdoor use or in brightly lit indoor environments, activate the pulse mode. This mode extends the working range of the laser up to 200 feet when used with a compatible Huepar laser receiver (sold separately).

6.4 Selecting Laser Line Modes
The GK011SG can project a 180° horizontal line and a 120° vertical line. Short press the power button to cycle through the following options:
- Single Horizontal Laser Line
- Single Vertical Laser Line
- Cross Laser Line (both horizontal and vertical)
Selecting a single-line mode can help conserve battery power and extend operating time.

8. Maintenance
Proper maintenance ensures the longevity and accuracy of your laser level.
- Cleaning: Use a soft, damp cloth to clean the device. Do not use abrasive cleaners or solvents.
- Storage: Store the laser level in its hard carry case when not in use. The case is designed to be waterproof, dust-proof, and shockproof, providing optimal protection.
- Battery Care: Store the Li-ion battery in a cool, dry place. If storing for extended periods, charge the battery to approximately 50% capacity.

9. Troubleshooting
If you encounter issues with your Huepar Pro GK011SG, refer to the following common solutions:
- Laser Beam Flashing: If the laser beam flashes rapidly in self-leveling mode, the device is likely outside its ±3° self-leveling range. Adjust its position until the beam becomes steady.
- No Laser Beam: Ensure the battery is charged and correctly inserted. Check that the power button has been pressed.
- Dim Laser Beam: In bright conditions, activate pulse mode and use a laser receiver for better visibility. Ensure the laser lens is clean.
- Inaccurate Lines: Verify the device is on a stable surface and within its self-leveling range. If issues persist, the device may require calibration.
