Description
The Yato cross-line laser set 4D YT-30415 is a self-levelling green line laser that projects 16 laser lines in horizontal and vertical planes. The lines are visible on several walls at the same time, so levels and plumb lines can be marked around the room from a single position of the device. The working range is 25 m and the accuracy ±3 mm / 10 m.
The device levels itself automatically up to a tilt of ±3°. If the tilt is greater, the lines flash rapidly. In manual mode, self-levelling is switched off so that the lines can be projected at an angle, for example parallel to stairs. Pulse mode is intended for a laser receiver (purchased separately) outdoors or in very bright light, and the line brightness can be adjusted with the buttons.
The power source is a Li-Ion battery 3.7 V / 2400 mAh (8.88 Wh), giving an operating time of about 8 hours. The set includes two batteries and a charger, so one battery can charge while the other is in use. The spare battery is the Yato YT-30416.
The set includes a 1.2 m tripod, remote control, wall bracket, tripod adapter, metal plate, height-adjustable base and green beam viewing glasses. The handle of the device has magnets, and the base has a 1/4″-20 UNC thread. The laser class is 2, the wavelength 520–530 nm and the power no more than 1 mW. The enclosure rating is IP52.
Intended use and suitability:
The Yato cross-line laser set 4D YT-30415 projects horizontal and vertical lines onto surfaces for marking in renovation and construction work.
- Levels: a ceiling or floor line around the whole room for suspended ceilings, cabinets and the starting level of tiling.
- Plumb lines: vertical lines for partition wall frames, door and window openings and rails.
- Sloping lines: in manual mode, markings parallel to railings and stairs.
- Mounting: tripod, wall bracket, magnets or metal plate on concrete, plasterboard or wood.

Yato cross-line laser set 4D YT-30415 instructions for use:
- Charge the battery before use: the charger indicator light is red while charging and green when the battery is full. Unplug the charger as soon as charging is complete.
- Switching on: move the power switch to ON; self-levelling switches on automatically. The tripod thread must point downwards.
- Lines: the H button selects the horizontal lines (pressing again switches between ceiling and floor mode), the V button the vertical lines.
- Manual mode: hold the * button for about 2 seconds; do the same again to exit. Pulse mode: short press on the * button.
- Switching off: move the power switch to OFF, which locks the laser unit for transport.

Warnings:
- Laser radiation, class 2: laser light is hazardous to the eyes. Do not look into the beam and do not point it at people or animals.
- Not to be handled by children. Do not dismantle the device or the laser module, do not modify the device and do not drill holes in the housing.
- Do not use in potentially explosive atmospheres or near sources of ignition. Do not immerse in water; relative humidity no more than 85% without condensation.
- Use only the supplied battery and charger. Do not leave the device unattended while connected to a power source. Remove the battery for storage.
- Protect from impacts and high temperatures, for example in a closed car. Transport the device switched off with the laser unit locked.
Frequently asked questions (FAQ):
Why do the lines flash rapidly?
The device is tilted more than ±3°. Move it to a more level surface or adjust the base until the flashing stops.
Are the lines visible outdoors?
In sunlight or strong light, the working range and the visibility of the lines are reduced. Use pulse mode and a separately purchased laser receiver.
Do the supplied glasses protect the eyes?
No. The green glasses improve the visibility of the beam but do not protect against laser radiation.
How long does the battery last?
About 8 hours per charge and about 500 charge-discharge cycles. For long-term storage, charge the battery to about 70%.
Recycling instructions:
- Device and charger: waste electrical and electronic equipment (WEEE); take them to a WEEE collection point.
- Li-Ion batteries: take them to a battery collection point; a damaged battery must not be transported.
- Tripod and metal parts: to metal recycling. The case and plastics to energy waste, cardboard to cardboard recycling.
