What Is Bosch Rotary Laser Level?

A Bosch rotary laser level is an indispensable tool for anyone who works with their hands. It’s also known as a “handyman’s tool” because it helps you measure angles and heights quickly and easily.

A rotary laser level is a device that is used for measuring the slope of various surfaces. This can make horizontal and vertical measurements.

While they are most commonly used to make levels, they can also measure distance, find centers of circles, and lay out circular objects.

Bosch rotary laser levels are used to make straight lines on the surface you’re working on. The laser vertical beam displays on the receiver, on the same plane as the laser.

An additional mirror on the receiver allows the laser beam to be reflected along the length of the receiver.

In this article, we’ll talk about what exactly a rotary laser level is, its pros, cons, and uses.

Here’s how to use Bosch's rotary laser level

Bosch self leveling rotary laser level is great for many tasks requiring a straight line. The cross beam comprises a tiny red dot laser and a crosshair.

The crosshair is a small laser plane. The size of the layout beam is around a centimeter.

To use a Bosch rotary laser level, you need to adjust the height. First, set the base of the rotary laser level on a plane or level surface, then adjust the height of the instrument.

Normally, the laser plane is positioned on the highest emission area of the laser beam.

The Bosch rotary laser level can install a baseboard or a blind slat, to set a picture or a mirror, or to level a TV or a piece of furniture.

The laser beam emitted by the Bosch laser level is visible at night (up to 50 m) and during the day (up to 30 m).

How do you set up a Bosch rotating laser level?

Setting up a wired version:

The first step in setting up your level will depend on which type of system you have. If you’re using a wired version of the product, then follow these steps:

1. Connect the power cord from the wall or battery pack into the base unit via the AC plug. The red wire goes into the positive pole while the black wire connects to ground.

2. Plug one end of the leveling cable into the connector at the top right corner of the base unit.

Note: Some models may require two different connectors depending on how many cables you connect at once. Be sure to read the manual before connecting any wires.

3. Plug the other end of the leveling rotary laser kit cable into the second connector near the middle of the bottom edge of the base unit.

4. Turn on the unit by pressing the Power button until the green light turns orange. Once it presses OK to confirm.

Setting up a wireless version:

If you’ve purchased a wireless model, then follow these simple steps instead:

Connect the transmitter to the charging dock station, and then insert the laser receiver into the base unit, following the same directions above. 

Plug the transmitter into the USB port on the rear panel of the base unit, while leaving the receiver plugged into the charger. Pressing the POWER button should turn on the transmitter.

Once the LED indicator turns blue, remove the transmitter from the computer and place it next to the receiver.

Turn off the base unit by holding down the ON/OFF switch. After turning it back on, wait for the LED indicators to show it is ready. When all LEDs are lit, press OK to complete setup.

To change between modes, simply hold down the Mode Switch button and select the desired mode.

You can access more information on each function through the user’s guide provided when purchasing the item.

Yes, they are very popular because they provide instances accuracy results with minimal effort. You don’t even need to measure out every inch.

Just point and shoot. They also come in handy when measuring odd angles and corners, as well as cutting lines across walls and ceilings.
