Q: How to vacuum water and liquids with the VC 40MX vacuum cleaner?

The VC 40MX is capable of vacuuming water and liquids. Its 30-liter tank has a usable water capacity of 22.8 liters , allowing it to handle a significant amount of wet waste. Preparation and use Preferably use a dedicated filter cartridge for wet debris . This protects your main filter from moisture-related damage. The VC 40MX features a water level monitoring system with automatic shut-off , which turns off the device when the tank reaches its limit. After wet vacuuming Allow the filter cartridge to dry completely before the next use. Thoroughly clean the collection tank after each wet use to avoid residues and unpleasant odors.

Question 1

How to start the HILTI VC 40MX vacuum cleaner?

Accepted Answer

Before starting, make sure that:

The appropriate dust bag is installed (mineral/wood, dry/wet according to use)
The filter cartridge is in place
The suction hose is connected
The suction head is properly locked onto the tank

Standard operation (without power tool):

Plug in the power plug
Turn the switch to the ON position (on)
The vacuum cleaner starts immediately

Operation with power tool:

Connect the power tool to the vacuum cleaner socket
Plug the vacuum cleaner into the power supply
Set the switch to Auto position
Turn on the tool - the vacuum cleaner starts automatically

In Auto mode, the vacuum cleaner stops automatically when you turn off the tool.

Question 2

How to adjust the slope (fall/slope function) on the HILTI PR 300HV2S?

Accepted Answer

The HILTI PR 300HV2S does not have a manual slope adjustment function (fall/slope). This device is a self-leveling rotary laser designed to establish a horizontal plane, not to create intentional slopes.

Self-leveling range: The device can operate automatically on slightly inclined surfaces up to ±5° maximum. If the slope exceeds this limit, the laser will blink as an error signal and will not operate.

Vertical adjustment available: You can use the arrow keys on the control panel (or the remote control if available) to move the laser plane up or down in parallel. This adjustment simply changes the height of the plane on a horizontal surface, without creating a slope.

If you need to create regular gradients: The PR 300HV2S is not suitable for sloped work. Please refer to other Hilti laser level models specifically designed for gradient measurements or applications on inclined surfaces, such as the PR 2-S or multifunction solutions.

Question 3

What is the cutting disc model for cutting steel on the HILTI SCM 22-A saw?

Accepted Answer

The HILTI SCM 22-A circular saw does not use interchangeable removable discs. This machine is equipped with a fixed, non-replaceable circular blade with a diameter of 110 mm, designed by HILTI for precise cutting operations in steel and ferrous materials.

This blade is an integrated element optimized for this saw. If you need to replace the blade due to wear, you must contact HILTI's technical service or an authorized dealer, who can offer you a repair or a complete part replacement.

For any spare parts orders, please have your device's serial number (visible on the nameplate) and contact:

Question 5

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 6

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.
