Question 1

How to adjust the height of the HILTI PMC 46 laser level?

Accepted Answer

The HILTI PMC 46 laser level is equipped with an automatic self-leveling system that corrects horizontal alignment in about 3 seconds. To adjust the height of the PMC 46, start by preparing a stable and horizontal surface: place the level on a tripod (provided in the toolbox version) or on any flat and stable surface, such as a workbench or work stand. Avoid vibrating or excessively sloped surfaces, which could affect accuracy.

Securely attach the laser level to your support using the UNC ¼" threaded fixing screw. If you are not using a tripod, you can adapt the PMC 46 with compatible Hilti accessories: the PMA 74 magnetic holder for metal surfaces, the PMA 25 universal clamp for various types of fixing, or the PMA 20 adjustable holder for flexible positioning.

To adjust the precise height, use the tripod mechanism with its telescopic sections or its crank. Raise or lower the device until you reach the desired position. The PMC 46 should always be placed on a surface as horizontal as possible: its self-leveling system only corrects inclinations up to a maximum of ±5 degrees. Beyond that, the laser will blink rapidly to warn you that the device needs to be repositioned.

Once the PMC 46 is in place, turn it on by pressing the control button once. The device will self-level automatically, which takes about 3 seconds. You will then see the horizontal and vertical laser lines displayed, as well as the intersection point. The built-in LED confirms that the operation is normal.

Check the horizontality by observing the integrated pendulum visible through the device's window. For work requiring high precision, place your reference surface at an optimal distance: up to 10 m for the lines and the intersection point (accuracy ±1.5 mm), or up to 30 m for individual points (accuracy ±3 mm). The PMC 46 offers an accuracy of ±1 mm/m and operates within a temperature range of 0 to 40 °C.

Before starting your leveling or alignment work, ensure that the area is secure and never direct the laser beam towards other people. The device automatically turns off after 15 minutes of inactivity to save batteries, but you can maintain continuous operation by pressing and holding the control button for 4 seconds until the beam blinks three times in confirmation.

Question 2

Which chisels are compatible with the Hilti TE 50 drill?

Accepted Answer

The Hilti TE 50 drill is compatible with several types of chisels suitable for different demolition and drilling tasks. Here are the main types of chisels you can use with this tool:

Flat chisel: ideal for demolishing flat surfaces, removing materials, or breaking coatings.
Pointed chisel: designed for drilling or splitting hard materials, useful for precision work or starting holes.
Chisel: used for sculpting, shaping, or finishing surfaces in concrete or stone.

To ensure optimal compatibility, it is important to choose chisels specifically designed to be used with the Hilti TE 50 attachment system. These chisels are generally marked as compatible with Hilti TE 50 tools or with SDS Max drills, which is the type of attachment used by this model.

In summary, prioritize SDS Max chisels suitable for demolition and concrete work, depending on your specific needs.
