How to Use a Laser Level

From Johnson Level, you can choose from a wide variety of different laser levels. Depending on the length of the project, we are able to provide you with a variety of different options.

Working outside? A laser outside can be difficult to see, if not impossible, with just the naked eye. Thankfully, most modern laser levels from Johnson Level come with red or green tinted glasses or goggles that make observing laser beams outside easy. Laser levels with rotaries are the best choice for outdoor use.

Working indoors? If you need to display horizontal and vertical lines across walls within an enclosed space, you will require dot laser levels. Interested in using Johnson Level’s many different kinds of laser levels as part of your next project? Read on below for a handful of helpful guides.

How to Choose a Laser Level

  1. Indoor project? Multiple-line lasers are effective in small rooms, such as those used for aligning kitchen cupboards or framing pictures.
  2. Outdoor project? Pulsed/detector lasers can be used on uneven surfaces and long distances, as well as rotaries and line lasers.
  3. Measure the room size or the distance that the laser must travel. Light with a low rotational frequency (RPM) travels farther, but the laser does not, because it is brighter. The laser is fainter when the RPM levels are high, but it travels further.
  4. It is important to consider the wall type. Laser levels are attached with pins or suction cups. Laser levels with push pins should not be used on wallpaper or paneling.
  5. Make sure the job is stable. When you are working indoors, a laser level can be useful. For outdoor projects with uneven surfaces, you will need a self-leveling laser level.

How to Use a Laser Level

  1. A tripod or flat surface should be used for setting up the laser level.
  2. It is important to ensure the bubble vials are level when using a manual level. The small screws can be found near the vial. A level bubble vial should appear when they are adjusted.
  3. Switch on the laser level.
  4. When it is a self-leveling model, allow it to self-level for a moment.
  5. The unit emits a laser beam as a levelling device, either on a wall or across a workspace (if the unit uses dots, multiple lines, or rotary lasers, it might show level in 360 degrees horizontally or vertically).
  6. The laser can be intercepted using a laser detector if a wall is not present to “catch” it (typically outdoors).
  7. Measure the distance between the detector and the rod.
  8. The detector should be adjusted so it beeps when you lift and lower it. This means the detector has located the laser.
  9. It seems that you have found the level. Install the detector on the rod and make the necessary measurements.

How to Use a Laser Level Outdoors

  1. Put on the tinted glasses/goggles included with your laser level kit. In order to see a laser beam in an outdoor setting, you’ll need these.
  2. On the tripod, mount the laser level and turn it on.
  3. Take a reading with the laser level by aiming it in the desired direction. Using the laser level, lock the level into position after finding it.
  4. Take the laser receiver to the location where you want to take a reading. Place it several inches above the laser level, either with the magnet that came with it or on a flat surface. It is a great idea to have a second tripod on hand here.
  5. Move the laser receiver slowly until it captures the laser beam from the level. After finding the beam, lock the receiver into position (if on a tripod or grade rod) or steady it (if on a flat surface or attached by magnet).
  6. Find the alignment or state of level you want using the level and receiver.

How to Use a Laser Level to Hang Pictures

  1. Decide what height you want the picture frame to have at the top.
  2. At this height, you can leave your mark anywhere.
  3. The laser level should be turned on and the laser mark should be aligned horizontally along the wall.
  4. Using the pivot point where the laser and mark meet, adjust the level so that the bubble sits between the black lines on the vial.
  5. When the laser is level and it passes through the mark, snugly attach it to the wall. There are levels that use putty and suction cups.
  6. Observe the distance between the top of the picture frame and the unique hanging mechanism(s).
  7. The distance between the laser and where the mechanism meets the wall should be determined on the wall.
  8. A nail should be driven into the wall at the mark.
  9. Line up the top of the picture frame with the laser and place the picture frame on the nail.

How to Use a Laser Level to Level Ground

  1. Put the laser level on a tripod and place it on a stable surface.
  2. The laser level should now be on.
  3. Please give it time to level out.
  4. Find a point at the height you desire on the ground.
  5. The laser detector should be attached to a measuring rod and the rod should be positioned at this point.
  6. The laser detector should be adjusted up and down. The sound of beeping indicates that you have reached level. The detector should be tightened to the pole.
  7. The rod’s bottom is the height you want to achieve on the ground.
  8. Locate another spot on the ground and find out how high the detector intercepts the laser.
  9. A stick or pile of dirt dumped at the desired height may be used to mark the height.
  10. This process should be repeated until you have enough reference points to fill the entire area.

How to Use a Laser Level to Set Grade

  1. Install the laser level on a tripod on firm, dry ground. The tripod should be stable.
  2. Give the laser level some time to self-level.
  3. Find out your grade’s height at the start. The pitch of the grade descends from here.
  4. A leveling rod should be positioned at the desired height.
  5. The laser detector needs to be adjusted until you hear a beep.
  6. Take steps to secure the detector.
  7. The desired fall between grades should be determined. In this example, let’s assume that the fall was 10 inches.
  8. Move the laser detector 10 inches up the rod and secure it.
  9. Make your way to where the grade will be at the bottom.
  10. With the laser detector, find the level. Depending on the workspace, you will have to lift the rod (most likely) or dig in the ground.
  11. The bottom of the leveling rod corresponds to the bottom of the grade.
  12. Mark the spot with a stick indicating the desired height.
