Safety Instructions
Please read thoroughly and comply with the Safety Instructions and User Manual before using
this product. Failure to read and follow may void the warranty.
WARNING!
Class 2 Laser Product
Max. Power Output: ≤ 1mW
Wavelength: 510nm-640nm
LASER RADIATION:
DO NOT STARE INTO BEAM.
DO NOT DIRECT EYE EXPOSURE.
ACOID VIEW WITH OPTICAL INSTRUMENTS.
ATTENTION:
Read all instructions prior to operating this laser tool. Do not remove any labels from tool.
• Do not set up laser tool at eye level or operate the tool near a reflective surface as the laser
beam could be projected into your eyes or into the eyes of others.
• While the product is in operation, be careful not to expose your eyes to the emitting laser beam
(Green/Red light source). Exposure to a laser beam for an extended time may be hazardous to
your eyes.
• Do not attempt to view the laser beam through optical tools such as telescopes as serious eye
injury may result.
• Do not disassemble or modify the laser in any way. Modifying the tool may result in hazardous
Laser Radiation Exposure.
• Do not operate the laser around children or allow children to operate the laser. Serious eye

injury may result.
• An exposure to the beam of a Class 2 laser is considered safe for a maximum of 2 seconds.
Eyelid reflexes will normally provide adequate protection.
• The following label/print samples are placed on the product to inform of the laser class for your
convenience and safety.
User Guide, Maintenance and Care
• When not in use please power OFF the tool and place the pendulum lock in its locked position.
• In Manual Mode, self-leveling is OFF. The accuracy of the beam is not ensured to be level.
• The laser tool is sealed and calibrated at the plant to the accuracy specified.
• It’s recommended to carry out an accuracy check before its first use and periodic checks during
future use especially for precise layouts.
• Do not store the laser tool in direct sunlight or expose it to high temperatures.
The housing and some internal parts are made of plastics and may become deformed at high
temperatures.
• Exterior plastic parts may be cleaned with a damp cloth. Although these parts are solvent
resistant, NEVER use solvents. Use a soft, dry cloth to remove moisture from the tool before
storage.
• Store the tool in its case when not in use. If storing for extended time, remove batteries before
storage to prevent possible damage.
• Do not dispose of this product with household waste.
• Always dispose of batteries per local code.
• Please recycle in line with local provisions for the collection and disposal of electrical and
electronic waste under the WEEE Directive.
Battery Safety
• Keep the battery away from children, and pets.
• Please pay attention to the position of the positive and negative pole.
• Please replace new alkaline batteries instead of carbon batteries. The battery capacity should
be more than 1500mA each.
• Do not mix old and new batteries. Replace all of them at the same time with new batteries of
the same brand and type.
• When the device will not be used for a long time, please remove the batteries and store them
in dry condition.

Operation Modes
Turn ON the laser tool:
•Method 1: Slide the side switch to the Unlocked Position to turn on the laser tool.
•Method 2: When the pendulum in Locked Position, press operation button and hold for ≥ 2
seconds to turn on the laser tool.
•The LED Indicator will light up when the laser tool turn on.
Lines switching:
•Short presses of the operation button repeatedly to switch the composition of different laser
lines.
• Laser line will switches in the following order:
①All lasers light up ⇒②Horizontal Line ⇒③Vertical Line ⇒④Horizontal Line + Vertical Line
⇒⑤Down Dot + Up Dot
Switch to Pulse Mode:
•Short press of the Pulse button to turn the Pulse Mode on, the LED Indicator will light up.
Note: The laser beam is dimmer in pulse mode.
Turn OFF the laser tool:
If the laser tool is in self-leveling mode: Slide the side switch to the Locked Position to turn laser
tool OFF.
If the laser tool is in manual mode:
• Method 1: Slide the side switch to the Unlocked Position, and then slide the pendulum again to
the Locked Position to turn laser tool OFF.
• Method 2: Short press of the operation button to switch the laser line in order. After “⑤Down
Dot + Up Dot”, short press of the operation button again to turn laser tool OFF.
Note: The laser level can only be turned off when the side switch is in its Locked Position.
Self-leveling Mode
• is enabled when the laser tool is switched to the unlocked position.
• the laser will blink fast when tool is out of self-leveling range (±3.5°).
Note: When using Self-leveling mode, please place this laser tool on a level surface.
Manual Mode
• Slide the side switch to the Locked Position, then press Laser button and hold for 3 seconds to
turn on the manual mode.
• The laser beam(s) will blink about every 3-5 seconds to notify the user

METSYS ML2/3 LINE LASER OPERATTING MANUAL
Pulse Mode
•Under pulse mode, Laser tool can work with a laser detector for working in a brighter
environment or a larger working distance.
Under Pulse model, the laser beam will enter into power-saving condition, which leads to
longer battery life. Users are recommended to use this model for green beam in indoor
uses.
• Turn on the laser tool, short press of the Pulse button will turn the Pulse Mode on and the LED
Indicator will light up. The laser beam is dimmer in pulse mode.
• Press and hold the Operation Button again for 3 seconds to back Normal Mode, and the
brightness of the laser line will return to normal.
• Please turn on the pulse mode when using the laser detector.
