Laser is level but out of level light blinks and will not spin

Here are the steps you can follow:

Set up the laser level on a flat surface or tripod and turn it on.

Place a target or receiver on a wall or surface where you want to project the laser beam.

Adjust the receiver to the same height as the laser level.

Align the laser level with the target or receiver.

Rotate the laser level 180 degrees and align it with the target or receiver again.

Check the readings on the receiver. The difference between the two readings should be less than or equal to the accuracy specification for the laser level.

If the readings are not within the specified accuracy, adjust the laser level until they are. Use the adjustment screws on the laser level to fine-tune the alignment.

Repeat the calibration process if necessary.

Note: Before calibrating your laser level, make sure it is clean and free from any debris or damage that may affect its accuracy. Additionally, consult the user manual for specific instructions and safety guidelines.

Rotate the laser to center horizontal (H) or vertical (G) bubble vials

The handhelds are not meant to be calibrated, recycle properly and invest in a PLS3 or PLS5, they have a 3 year exchange warranty: https://www.plslaser.com/pls-best-class-warranty/

Set it up and shoot 4 level points around the laser . Like at 12 -3-6and 9 o clock. Move the laser 15 or 20 ft from where it is now and re-shoot those 4 points again .if they don't read level then your laser needs calibrated

There is no "calibration mode".

To check calibration set the tool on a fixed surface. turn it on. let it autolevel, then mark the wall with a pencil at a distance of 15- 20 feet. rotate the laser on its axis 90 degrees, and see if it self levels to the same line. if it does not, send it to hilti, you'll have it back in a week.

There are two brass screws under the upper most metal plate. They are the calibration adjustment screws. The manual tells you how to do a peg test. If your peg test is out, move the corresponding screw until you reach the calibration point you want.

This is not a battery problem. It likely levels to the back corner, then to the front corner then roughly back to the middle and spins at about 150 rpm and the lights on the front blink.

There are a couple things that can cause this. the most common is the the compensator cant find the laser. 5 screws hold the main housing on to the base. Remove the housing and inspect. if the internals are coated in oil, then the unit is done. The replacement part is too expensive.
If the inside is dry, there is a small circuit board on the left side of the metal compensator frame. Resolder the pins in the board, and the connector going to the side board, located on the main board. about 30% of the time, this will get the laser running again. If not, the laser diode is likely dead, and it's not repairable.

i think its selflevelling at that moment. i heard before that its not starting after levelling. when levelled you can try to switch off and on again.

this unit does not have any replaceable parts, if the unis is covered by warranty, it would be exchange, if not then check with your local servicenter the max rate program to do so.

Could be the printhead is at the right margin. But, if you hit the return key and nothing happins, it could be a bad board, power supply or transport motor. When you turn the machine on, does the printhead move all the way to the left, spin the printwheel and move to a set position?
