Using a Laser Level Step by Step
Using a laser level to create straight reference lines isn’t difficult to use if you choose the right device for the job. For most home projects, like hanging artwork, shelves and wallpaper, you'll likely use a standard line generator. We’ve got general steps for using a DIY-grade line generator laser level below. However, specific instructions vary by model and level type. Follow the instructions for your device.
Step 1: Position the Level
Make sure the level is turned off. Set the device so the beams will give you the reference line you need.
- For a handheld line laser level, hold the device against the wall or hang it on the wall using the included pins, bracket or adhesive pad.
- If your device includes a stand or tripod, attach the level to the support and adjust it so it will direct the beam along the wall, workpiece or floor.
Step 2: Turn the Level On
Make sure no people or pets are in the line of the beams and turn the level on. Some levels let you project beams in different directions. Set the device for your project.
Always be aware of where the beams are pointing.
Step 3: Adjust the Level
Adjust the level so the beams give you the alignment line, horizontal level or vertical plumb line you need.
- Some levels include bubble vials like those on a standard level to help you set the device for accurate lines.
- If your model has a self-leveling feature, you might need to turn it on or off, depending on the type of reference line you need.
Step 4: Use the Reference Lines
How you use the beams depends on your project and level. For example:
- Use a horizontal beam to position and hang pictures or install shelves on a wall.
- Use a vertical beam to hang wallpaper accurately.
- Use both horizontal and vertical beams to install wall tile or hang cabinets.
- Project a beam across a floor to align tile or install laminate flooring.
Step 5: Store the Level
Turn the level off and store it out of the reach of children. Make sure the level is protected from bumps and falls.
If you're working outdoors, make sure you have a level designed for outdoor use. Green-light beams are typically easier to see outdoors.
Laser Level Safety Tips
Like any tool, you need to pay attention to safety when using a laser level. Follow the safety instructions for your level. Here are some general tips:
- Keep the device away from children.
- Don’t use the level if it appears to be damaged.
- Do not look directly into the beam or emitter inside the level.
- Don’t look at the beam using any type of magnifying lens, optical device, etc.
- Keep the beam pointed away from people, animals, vehicles, etc.
- Make sure the level is secure on the wall or a stand when you’re using it.
Other Laser Levels
In addition to the line generator laser level, there are other types for different applications and with different instructions for use:
- Cross-line laser levels project perpendicular horizontal and vertical lines.
- Plumb-point or dot laser levels project dots rather than lines.
- Rotary lasers project 360-degree planes of light.
- Combination levels have selectable modes, for example line and dot modes, for different applications.
