4. Setup

4.1 Battery Installation and Charging

  1. Open the battery compartment cover on the back of the laser level.
  2. Insert the detachable lithium-ion battery, ensuring correct polarity.
  3. Close the battery compartment cover securely.
  4. To charge, connect the Type-C power cord to the laser level's charging port and the power adapter, then plug into a power outlet. The battery indicator lights will show charging status.

4.2 Mounting Options

The GM120 offers versatile mounting for various applications:

  • Mini Tripod (360° Free Rotating Base): Attach the laser level to the included mini tripod using the 1/4" mounting thread. This allows for precise rotation and placement on flat surfaces.
  • Standard Tripod/Mounting Pole: The device features a 1/4" mounting thread for direct attachment to standard tripods. The rotating base also has 1/4"-20 and 5/8"-11 mounting threads for compatibility with different tripod types.

5. Operation Modes

5.1 Self-Leveling Mode

This mode is suitable for applications requiring precise horizontal and vertical alignment. The device will automatically level itself within a ±4° range.

  1. Place the laser level on a stable surface or mount it using one of the available options.
  2. Unlock the pendulum by sliding the lock switch to the "UNLOCKED" position.
  3. The laser lines will activate and self-level. If the device is outside its ±4° leveling range, the laser lines will blink rapidly to indicate it cannot self-level. Adjust the device's position until the lines become steady.

5.2 Manual/Tilt Mode

Use this mode when projecting lines at an angle, such as for staircase installations or decorative patterns.

  1. Lock the pendulum by sliding the lock switch to the "LOCKED" position.
  2. Press and hold the "V" button on the control panel (or remote) for approximately 2 seconds to enter manual mode. The indicator light will illuminate.
  3. The laser lines will now be projected at the angle the device is positioned, without self-leveling.

5.3 Pulse Mode (Outdoor Mode)

Pulse mode is designed for use with a laser receiver (sold separately) in bright light conditions or outdoors to extend the working range.

  1. Ensure the laser level is in self-leveling mode (pendulum unlocked).
  2. Press and hold the "H" button on the control panel (or remote) for approximately 2 seconds to activate pulse mode. The indicator light will turn on.
  3. The laser lines will now emit a pulsed beam, allowing detection by a compatible laser receiver.

6. Operating Instructions

6.1 Turning On/Off and Line Selection

  1. Power On: Slide the pendulum lock switch to the "UNLOCKED" position to turn on the laser level and activate self-leveling mode.
  2. Line Selection:
    • Press the "H" button to cycle through horizontal laser lines (one 360° horizontal line).
    • Press the "V" button to cycle through vertical laser lines (two 360° vertical lines).
    • Pressing both "H" and "V" buttons allows for various combinations of horizontal and vertical lines.
  3. Power Off: Slide the pendulum lock switch to the "LOCKED" position to turn off the laser level and protect the pendulum during transport.

6.2 Using the Remote Control

The included remote control allows for convenient activation and deactivation of laser lines without touching the device, preventing accidental movement.

  • Ensure the laser level is powered on.
  • Use the "H" button on the remote to control horizontal lines.
  • Use the "V" button on the remote to control vertical lines.
  • The remote can also activate/deactivate pulse mode by holding the respective button for 2 seconds.

7. Maintenance and Care

  • Cleaning: Wipe the device with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners. Keep the laser apertures clean.
  • Storage: When not in use, store the laser level in its protective carrying case with the pendulum locked. Remove the battery if storing for extended periods to prevent drainage.
  • Calibration: While the device is factory calibrated, regular checks for accuracy are recommended, especially after drops or impacts. Refer to professional calibration services if significant deviations are observed.
  • Battery Care: Charge the battery regularly, even if not in use, to maintain its lifespan. Avoid fully discharging the battery.
