A rotating laser is a precision instrument that lives on the construction site – in dust, rain and frost. The IP54 protection can withstand a lot, but a few simple habits will determine whether it will measure accurately for you even in five years.
Batteries and charging
- The laser uses 4 D-size Ni-MH cells ; one charge lasts for approximately 20 hours of operation, charging takes approximately 10-12 hours.
- Charge overnight , not after an hour - a full charge extends the life of the cells.
- If you do not use the laser for a long time (e.g. during the winter), charge it at least once every 2-3 months.
- Alkaline batteries will also work in an emergency - but never charge them with a charger.
- When storing the device for a long time without batteries, remove the batteries from the device.
Cleaning the optics
The windows around the rotating head are the laser's "eyes." Dust and dried concrete droplets weaken the beam and shorten its range.
- Blow off the dust first, then wipe.
- Use a soft microfiber cloth, possibly moistened with clean water.
- Do not use solvents or rough cloths - they will scratch the window.
Transportation
- Always carry the laser in a case , never loose on the seat or in the trunk.
- Turn it off before transporting it - this will prevent strain on the self-leveling mechanism.
- Secure the suitcase in the car so it doesn't fall.
Working in winter and rain
- The laser operates from approximately −20 °C to +45 °C .
- When you bring the device from freezing to warm weather, leave it in the case with the door ajar until the temperature equalizes - this will prevent condensation inside.
- After working in the rain , dry the laser and leave the case open until it dries. A wet laser in a closed case is the most common cause of contact corrosion.
- Frost shortens the life of batteries - expect to have to charge them more frequently.
Accuracy check
After a tripod drop or once a year, check the laser with a simple test between two walls (we have a separate blog post on this). If the deviation is out of tolerance, send the laser to us for calibration - we also do it for lasers from other brands.
Spare parts
We have receivers, tripods, battens, chargers and mounts in stock. If something is working for you, you don't have to buy the whole set - just give us a call.
