Yato Cross Laser Set with 4D Green Laser (YT-30415) is an advanced measuring device designed for professional use, enabling extremely accurate and efficient alignment and leveling in various construction and installation jobs. This 4D laser projects as many as sixteen (16) green laser lines, four lines for each plane. This comprehensive line system allows you to obtain horizontal and vertical lines on any wall simultaneously and in real time, which significantly speeds up and refines workflows. The green laser beam is up to four times more visible than a traditional red laser beam in bright indoor conditions, which improves user comfort and reduces eye strain.

The device’s self-leveling mechanism ensures fast and automatic alignment within a range of ±3 degrees, eliminating the need for manual adjustment and reducing the possibility of errors. If the device tilts outside the self-leveling range, a built-in alarm function notifies the user, ensuring that measurements are always made accurately and reliably. The pulse function also allows the device to be used with an optional laser receiver, which extends the working range and improves visibility in more challenging conditions or outdoors.

The Yato Cross Line Laser Set is equipped with a durable Li-Ion battery that provides up to 8 hours of operation on a single charge. The two rechargeable batteries and charger included ensure uninterrupted work for longer periods. In addition, the set includes a wide range of accessories, such as a 1-meter high aluminum tripod with adapter, remote control, wall mount and adjustable base, which increase the versatility and usability of the device in various working environments. All components are packed in a sturdy, vibration-absorbing case, which protects the device during transport and storage.

The durability of the device is emphasized by its IP52 rating, which guarantees protection against dust and splash water. This makes it suitable for demanding working conditions. The green laser has a wavelength of 520-530 nm and a power of ?1 mW, which places it in laser class 2. This ensures efficient performance while taking safety aspects into account. The Yato Cross Laser Series 4D is an excellent choice for professionals looking for a reliable, accurate and versatile solution for their alignment and measurement needs.

Yato Cross Laser Set 4D user manual:
Getting Started and Installing Batteries: The laser level package includes the laser level, batteries, charger and other accessories. Before first use, make sure that all parts are present and intact. The device is supplied with two Li-Ion batteries (YT-30416), which must be fully charged before use with the included charger. The batteries are placed in the battery compartment at the bottom of the laser, observing the correct polarity. Make sure that the battery compartment is properly closed.

Starting the device and self-leveling: The device is turned on with the ON/OFF switch. The laser level automatically starts self-leveling when it is on a horizontal surface. The self-leveling range is ±3 degrees. If the device tilts outside this range, the laser beam will flash and/or an audible signal will sound to indicate an error. Move the device to a more level surface or adjust with a tripod until it is within the self-leveling range and the lines are level.

Laser mode selection:

Horizontal planes: You can select which horizontal and vertical planes are active using the device buttons or the remote control. Yato 4D projects four horizontal planes and four vertical planes.
Pulse Mode: Pulse mode activates the laser beam to pulse, allowing the use of an optional laser receiver. This improves visibility over long distances or outdoors.
Tilt mode (manual mode): If you want to project tilted lines (e.g. to align stair railings), the self-leveling function can be turned off. In this mode, the laser will not indicate if it is not horizontal or vertical, so the accuracy of the line is the responsibility of the user.

Mounting and positioning the device: The Yato Cross Laser Set can be placed directly on a flat surface, attached to the supplied tripod with a 1/4" thread, or using the supplied wall mount or adjustable base. The tripod allows for height and angle adjustment. The wall mount is useful for marking, for example, the tops of ceilings or walls.

Maintenance and storage:

Cleaning: Clean the laser lens and housing regularly with a soft, lint-free cloth. Do not use solvents or abrasives.
Calibration: The manufacturer recommends regular calibration checks to ensure accuracy. Instructions for checking calibration can usually be found in the user manual that came with the product.
Storage: When not in use for a long period of time, remove the batteries. Store the device in a dry and dust-free place, preferably in the sturdy case provided. Avoid extreme temperatures (storage temperature range -20°C to +70°C).

How to choose the right cross laser set:
Choosing the right cross line laser set depends on many factors, including the intended use, required accuracy, working conditions, and budget. Here are some key things to consider when choosing the right device:

Laser class and power: The most common lasers used in construction are class 2. They are safe under normal operating conditions, but the laser beam should not be looked into directly. The power (usually ?1 mW) affects the brightness of the beam. Make sure the device complies with local safety regulations.
Number and type of lines (2D, 3D, 4D):

2D lasers project one horizontal and one vertical line (cross line). They are suitable for basic alignments.
3D lasers project multiple lines, usually one horizontal and two vertical lines (360° lines in total), covering the entire room. They are effective for aligning large spaces.
4D lasers (like this product) are the most advanced and project up to four 360° lines (two horizontal and two vertical lines) for exceptional alignment coverage on all surfaces simultaneously. Choose the number of lines according to your needs.

Laser beam color (red or green): A green laser beam is significantly more visible in bright light conditions and over longer distances than a red one, which can be crucial when working indoors or semi-outdoors. Green lasers tend to be more expensive, but their better visibility can improve work efficiency.
Working range and accuracy: Estimate how far you need the laser lines. The working range can vary from a few meters to tens of meters. The accuracy (e.g. ±3 mm / 10 m) tells you how much deviation is allowed for a given distance. More accurate lasers are more expensive, but essential for precision work.
Self-leveling and grade function: Most modern lasers are self-leveling, making setup quick and easy. Check the self-leveling range (e.g. ±3-4°). If you need the ability to project sloped lines (e.g. for aligning stair railings or drain pipes), make sure the device has a manual mode or grade function.
Battery and power supply: Check the battery type (e.g. Li-Ion, AA) and capacity. Long battery life and the ability to use rechargeable batteries or multiple batteries increase flexibility in your work. Some models can also operate directly from mains power.
Durability and protection class (IP rating): For use on construction sites, the device must be durable. The IP rating indicates the device's protection against dust and water (e.g. IP54, IP65). A higher IP rating means better protection.
Accessories and Compatibility: Consider what accessories you need. A tripod, wall mount, remote control, laser receiver, and goggles are common and useful accessories. Also, check if the device has a standard thread (e.g. 1/4" or 5/8") for a tripod.
User interface and ease of use: Choose a device with a clear and easy-to-use interface, even if you are an experienced professional.
