The LaserMark LMH series self-leveling laser can be a timesaver for marking when used in construction projects, such as road and driveway paving, and countless site preparation tasks. Since the self-leveling laser is commonly depended on for measurement accuracy, when it malfunctions, it can affect work progress on a large or small construction site. What enables the laser to function could be the likely source to examine when it fails. Begin troubleshooting your LaserMark by inspecting its batteries and those parts that it come in closest contact to them.

Inspect the batteries to be sure that none are defective. If even one battery is flawed, performance is severely affected. Test each battery with a battery tester or voltmeter. If one is found defective, replace all batteries so that long-term performance is enhanced.
Reinstall all batteries correctly if not properly set.
Check for battery leakage. The battery box may be damaged if battery contacts are corroded. If this is the case, replace the battery box to prevent further damage to the laser tool.
Check that the battery tray is attached securely to the unit's base.
Check that the battery connections make contact with the battery prongs. Minor prong adjustments may also need to be made when different battery brands are installed at various times.
Turn the machine off and then turn it back on again to reset the internal processor.
