Troubleshooting Rotary Laser Levels To Solve Problem

A rotary level is a device for professionals that give the effect of full 360 degree horizontal and vertical plane. This device spins the beam quickly enough to process the operation, projecting a horizontal plane. Some troubles might be a nightmare for you, but troubleshooting rotary laser levels is something that you can do by yourself. Basically, there are two types of rotary laser levels—the self-leveling and the manual ones. Regardless of the types, a rotary laser level is also prone to damages and several troubles.

As troubleshooting rotary laser  can be done by any users, check out several tips and tricks to fix the minor problems below.

Troubleshooting Rotary Laser Levels: Affected Leveling

If you find your rotary laser level cannot give the perfect leveling, you cannot stay quiet. Troubleshooting rotary laser levels in terms of the incorrect leveling can be done in one simple way.  Avoid placing the devices where there are large machineries are operated as the heavy vibrations will affect the leveling or the alignments, hence the lines are unsteady. If the leveling or alignments are incorrect, it will surely affect the construction.

To solve this problem, you need to place the device on a firm and sturdy floor. Use a tripod or a pole leveling ceiling to floor if necessary. If you do not have any tripod or pole, you can mount the rotary laser level units to the wall.

Battery Failure during Works

Have you ever experienced a sudden on duty battery failure which made the device stop working? It can be risky in construction areas where the works have to be finished in one go. The solution for this problem is connecting the device with a DC power source or an external power supply. Always connect the rotary laser to the external power supply by combining AC/DC converter and battery charger, which usually comes with the device equipment. Using other materials may damage the rotary laser level.

Low Visibility of Laser Beam in Normal Light

Sometimes the laser beam emitted by the device is very low which makes the alignment become less visible in normal light, causing the users not being able to achieve the accurate result. You can fix it by changing or decreasing the rotating speed of the device. Usually, the speed is set in a default rotation mode. However, you can easily change it by using the buttons provided to change the speed of the rotation when needed. Alternatively, try to stop the rotation and readjust the position of the beam when you need to transfer it to longer distances.

Low Visibility of Laser Beam in Bright Light

It is true that bright lights or sunlight may hinder the rotary laser level device from projecting a visible laser beam. The most effective way to tackle this issue is to use a laser detector. By using a laser detector, the laser beam will be visible even in bright lights. The combination of laser detector and rotary laser level enhance the effectiveness of the leveling. If the laser level device is above the head height, you can try to attach the detector at a high level to boost the results.

Dead Area

When the laser beam of the rotary laser level cannot reach some dead areas because of obstructions, troubleshooting rotary laser levels is a must. The leveling will be heavily affected when the laser beam fails to reach all directions. When you face such problem, try to change the direction of the rotation. It is possible to shift the direction of the laser rotation to clockwise or anticlockwise mode as needed. However, only change the direction when the rotation speed is zero at 0 degree rmp or at scan mode. If you cannot change the direction even in 0 degree rmp, the device might be damaged, hence it fails to project laser to several areas.

Remote Control Failure

Keep in mind that the remote controls only work when there is the direct line of sight between the remote sensor and the sensor in the rotary device is uninterrupted. The remote control should only be used within its effective range. Change the batteries of the remote regularly or when required.

Rotary Laser Device Not Responding

When the rotary laser level device stops working, you should check the whole device carefully. Check the connection and the batteries, if both of them work just fine, check the joint of the rotary laser level just in case there is any corrosion. Treat the corrosion with anti-corrosion ointments, your rotary laser device should work perfectly.

Mishandled Device

When the device is dropped and mishandled, you have to check whether the device is working properly by performing a horizontal plane calibration test. You can test it by following these steps;

  • Set the rotary device at least 50 m from the wall
  • Allow the laser to point the X-axis towards the wall before turning it on
  • Mark the point of the beam
  • Turn the rotary to 180 degree and mark the point
  • Make sure that the difference between the heights of the points is not more than 10 mm
  • Do the same steps for the y-axis

Always perform the calibration test to ensure that the rotary device is fine. Ask professional help if necessary.


Any users can perform the solutions to the minor rotary laser level problems above. Follow the steps carefully and maintain your device properly afterward. Handling rotary laser levels is complicated, but if you know the basics in troubleshooting rotary laser levels, it will not be a problem. Remember, always store the device in cool and dry place.
