Figure 4.1: TOMAHAWK TLL-S-03 Laser Level Controls.
- On/Off Switch: Powers the device on or off.
- Vertical Switch: Activates or deactivates the vertical laser lines.
- Horizontal Switch: Activates or deactivates the horizontal laser line.
- Horizontal Bubble: Assists in rough manual leveling.
- Rechargeable Battery Compartment: Houses the lithium-ion batteries.
- 360° Rotation Adjustment: Allows for fine adjustment of the laser's rotational position on its base.
5. Setup
5.1 Battery Installation and Charging
- Open the battery compartment.
- Insert the two rechargeable lithium-ion batteries, ensuring correct polarity.
- Close the battery compartment securely.
- Before first use, fully charge the batteries using the provided charger. Connect the charger to the device and a power outlet. The charging indicator will show the charging status.
5.2 Mounting the Laser Level
- On a Flat Surface: Place the laser level on a stable, flat surface.
- Magnetic Base: Utilize the integrated 360° vertical/horizontal magnetic base to attach the laser level to metallic surfaces for versatile positioning.
- Tripod Mounting: The device may include a standard tripod thread for mounting on a compatible tripod (tripod sold separately).
6. Operation
6.1 Powering On/Off
Slide the On/Off switch to the 'On' position to power on the device. Slide it to 'Off' to power it down.
6.2 Self-Leveling Mode
- When powered on, the laser level automatically enters self-leveling mode.
- The device will self-level within a range of <3°.
- If the device is tilted beyond its self-leveling range, a buzzer alarm will sound, and the laser lines may flash to indicate it is out of level. Adjust the device's position until the alarm stops and the lines are stable.

6.3 Manual Mode
To project lines at an angle, switch to manual mode. This typically involves locking the pendulum by holding down a specific button or sliding a lock switch (refer to device specific controls). In manual mode, the self-leveling function is deactivated, allowing the laser to be locked at any desired angle.
6.4 Line Selection and Brightness
- Use the Vertical Switch to activate or deactivate the vertical laser lines. The TLL-S-03 projects two vertical lines.
- Use the Horizontal Switch to activate or deactivate the horizontal laser line.
- The device features adjustable brightness for optimal visibility in various lighting conditions. Consult the device controls for brightness adjustment options.
